PART I

ITEM 1.    BUSINESS

Overview

Spirit Airlines, Inc. ("Spirit Airlines"), headquartered in Miramar, Florida, offers affordable travel to value-conscious guests ("Guests"). Our all-Airbus fleet is one of the youngest and most fuel efficient in the United States. During 2023, we served 93 destinations in 15 countries throughout the United States, Latin America and the Caribbean. Our stock trades under the symbol "SAVE" on the New York Stock Exchange ("NYSE").

Our ultra low-cost carrier, or ULCC, business model allows us to compete principally by offering Guests unbundled base fares that remove components traditionally included in the price of an airline ticket. By offering Guests unbundled base fares, we give Guests the power to save by paying only for the À La Smarte® options they choose, such as checked and carry-on bags, advance seat assignments, priority boarding, refreshments and Wi-Fi. We record revenue related to these options as non-fare passenger revenue, which is recorded within passenger revenues in our consolidated statements of operations.

Our History

We were founded in 1964 as Clippert Trucking Company, a Michigan corporation. We began air charter operations in 1990 and renamed ourselves Spirit Airlines, Inc. in 1992. In 1994, we reincorporated in Delaware, and in 1999 we relocated our headquarters to Miramar, Florida.

HoldCo 1 and HoldCo 2 are special purpose holding companies. HoldCo 2 is a wholly-owned direct subsidiary of HoldCo 1 (other than the special share issued to the special shareholder, who granted a proxy to vote such share to the collateral agent for the 8.00% senior secured notes). HoldCo 1 is a wholly-owned subsidiary of Spirit Airlines (other than the special share issued to the special shareholder, who granted a proxy to vote such share to the collateral agent for the 8.00% senior secured notes).

Current Developments

JetBlue Merger

On July 28, 2022, we entered into an Agreement and Plan of Merger (the “Merger Agreement”) with JetBlue Airways Corporation, a Delaware corporation (“JetBlue”), and Sundown Acquisition Corp., a Delaware corporation and a direct, wholly owned subsidiary of JetBlue (“Merger Sub”), pursuant to which and subject to the terms and conditions therein, Merger Sub will merge with and into Spirit, with Spirit continuing as the surviving entity (the “Merger”). As a result of the Merger, each existing share of Spirit's common stock (except for dissenting shares, treasury stock, and shares of Spirit's common stock owned by JetBlue, Merger Sub or any of their respective wholly owned subsidiaries), will be converted into the right to receive an amount in cash per share, without interest, equal to (such amount, the “Merger Consideration”) (i) $33.50 minus (ii) (A) $2.50 (the “Approval Prepayment Amount”), paid on October 26, 2022 following the adoption by Spirit stockholders of the Merger Agreement on October 19, 2022, and (B) an additional monthly per share prepayment amount calculated as the product

4

of $0.10 and the number of additional prepayments paid (or, in the event the Closing occurs after the record date of, but before the payment date of any such additional prepayment, to the extent payable after the Closing), not to exceed $1.15 per share of Spirit common stock, by JetBlue to Spirit stockholders in accordance with the Merger Agreement (each such payment is referred to as an “Additional Prepayment” and such $0.10 amount is referred to as the “Additional Prepayment Amount”). If an aggregate of $1.15 of Additional Prepayment Amounts has been paid out before consummation or termination of the Merger, Spirit stockholders will thereafter continue to receive monthly Additional Prepayments, at the same $0.10 per month rate until the transaction closes or the Merger Agreement is terminated. The Merger Agreement becomes unilaterally terminable by either JetBlue or Spirit after July 24, 2024.

In accordance with the terms of the Merger Agreement, JetBlue is required to pay or cause to be paid the Approval Prepayment Amount to Spirit stockholders as of the record date established by Spirit for the special meeting to approve the Merger Agreement within five business days following such Spirit stockholder approval. Thereafter, on or prior to the last business day of each month beginning after December 31, 2022 until the earlier of the Closing or termination of the Merger Agreement, JetBlue will also pay or cause to be paid the Additional Prepayment Amount to Spirit stockholders as of a record date not more than five business days prior to the last business day of such month. Payments made from JetBlue to Spirit stockholders do not impact our results of operations or cash flows.

On October 19, 2022, Spirit’s stockholders approved the Merger Agreement at a special meeting of stockholders. The record date for both Spirit's special meeting and the Approval Prepayment was September 12, 2022. In accordance with the terms of the Merger Agreement, on October 26, 2022, JetBlue paid the Spirit stockholders the Approval Prepayment Amount of $2.50 per share. Additionally, beginning January 2023, JetBlue paid on a monthly basis the Additional Prepayments of $0.10 per share of common stock to all Spirit stockholders as of each record date per the agreement.

Due to the payment of the Approval Prepayment and each of the Additional Prepayment Amounts, in accordance with the terms of the respective debt indentures and warrant agreements, we announced related adjustments to the conversion rates of our convertible notes due 2025 and our convertible notes due 2026 as well as adjustments to the exercise prices and warrant shares of the outstanding warrants issued in connection with our participation in the Payroll Support Program authorized by the CARES Act (“PSP1”), as extended by the Consolidated Appropriations Act of 2021 (“PSP2”) and the American Rescue Plan Act (“PSP3”). As of December 31, 2023, the conversion rates of the convertible notes due 2025 and 2026 were 94.9262 and 24.6649 shares of voting common stock per $1,000 principal amount of convertible notes, respectively. In addition, as of December 31, 2023, the exercise prices of the PSP1, PSP2 and PSP3 warrants were $11.663, $20.229 and $30.196, respectively, and the number of warrant shares issuable upon the exercise of the PSP1, PSP2 and PSP3 warrants were adjusted to 628,725.19, 166,292.37 and 97,219.73, respectively.

Completion of the Merger is subject to the satisfaction or waiver of certain closing conditions, including, among other things: (1) approval of the transactions by Spirit’s stockholders, which was received on October 19, 2022; (2) receipt of applicable regulatory approvals, including approvals from the U.S. Federal Communications Commission, the U.S. Federal Aviation Administration and the U.S. Department of Transportation and the expiration or early termination of the statutory waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and other competition laws, and other required regulatory approvals; (3) the absence of any law or order prohibiting the consummation of the transactions; and (4) the absence of any material adverse effect (as defined in the Merger Agreement) on Spirit.

On March 7, 2023, the U.S. Department of Justice (“DOJ”) filed suit to block the Merger and a trial was held in late 2023. On January 16, 2024, the United States District Court for the District of Massachusetts (the “District Court”) granted a permanent injunction against the Merger (the "Injunction"). On January 19, 2024, Spirit and JetBlue filed a notice of appeal to reverse the District Court's decision and allow Spirit and JetBlue to complete the Merger. On January 25, 2024, JetBlue made a public filing stating that certain closing conditions required by the Merger Agreement may not be satisfied prior to the outside dates set forth in the Merger Agreement and, accordingly, the Merger Agreement may be terminable on and after January 28, 2024. We do not believe there is a basis for terminating the Merger Agreement, and we will continue to abide by all of our obligations under the Merger Agreement. On January 29, 2024, Spirit and JetBlue filed a request with the U.S. Court of Appeals for the First Circuit (the "Court of Appeals") seeking an expedited schedule for their appeal. On February 2, 2024, the Court of Appeals granted our motion, stating it would hear arguments in June 2024.

In addition, Spirit has agreed, among other things, that neither it nor any of its directors, officers, employees and representatives will (1) solicit alternative transactions, (2) participate in any discussions or negotiations relating to alternative transactions, (3) furnish any non-public information in connection with alternative transactions or (4) enter into any agreement relating to alternative transactions, except under limited circumstances described in the Merger Agreement. However, in certain circumstances, Spirit may terminate the Merger Agreement to enter into a definitive agreement for a Superior Proposal (as

5

defined in the Merger Agreement). In addition, Spirit, JetBlue and Merger Sub each make certain customary representations, warranties and covenants, as applicable, in the Merger Agreement.

The Merger Agreement contains certain termination rights for Spirit and JetBlue, including, without limitation, a right for either party to terminate if the Merger is not consummated on or before July 28, 2023 (the "Outside Date"), subject to certain automatic extensions up to July 24, 2024 if needed to obtain regulatory approvals. Since all regulatory approvals required to consummate the Merger were not obtained as of July 28, 2023 and January 28, 2024, the current Outside Date has been automatically extended to July 24, 2024. Upon termination of the Merger Agreement under specified circumstances, Spirit will be required to pay JetBlue a termination fee of $94.2 million. Upon the termination of the Merger Agreement by JetBlue because of a material uncured breach by Spirit of the Merger Agreement, Spirit will be required to pay JetBlue an amount equal to the sum of all amounts paid by JetBlue to the Spirit stockholders. Upon the termination of the Merger Agreement for failure to obtain antitrust regulatory clearance, JetBlue will be required to pay (i) to Spirit, $70.0 million, and (ii) to the Spirit stockholders, the excess of (A) $400.0 million minus (B) the sum of the Approval Prepayment Amount and all Additional Prepayment Amounts previously paid by JetBlue to the Spirit stockholders.

Pratt & Whitney

On July 25, 2023, RTX Corporation, parent company of Pratt & Whitney, announced that it had determined that a rare condition in the powdered metal used to manufacture certain engine parts will require accelerated inspection of the PW1100G-JM ("GTF") fleet, which powers our A320neo family of aircraft.

In September 2023, Pratt & Whitney notified us that all the geared turbofan GTF neo engines in our fleet, including the engines slotted for future aircraft deliveries, for a yet to be determined period, are subject to the inspection and possible replacement, of the powdered metal high-pressure turbine and compressor discs. In addition, Pratt & Whitney issued a special instruction ("SI"), requiring accelerated engine removals and inspections covering the initial tranche of operational engines, no later than September 15, 2023. As of December 31, 2023, in accordance with the SI issued by Pratt & Whitney, we have removed five engines from service, three of which are currently awaiting induction for inspection.

For the remaining engines, Pratt & Whitney has provided an initial analysis on an inspection and removal schedule for these engines. In addition, to the 5 engines removed from service, we had 12 neo aircraft grounded as of December 31, 2023 for reliability, durability, and inspection requirements combined. For 2024, we had an average of 13 grounded neo aircraft in January 2024, and we expect the average number of grounded neo aircraft will increase to approximately 40 in December 2024, averaging approximately 25 grounded for the full year. We currently estimate the majority of affected engines will require removal and inspection in 2024, but will continue through 2026, based on service bulletins ("SB") issued by Pratt & Whitney and related airworthiness directives issued by the FAA.

The temporary removal of engines from service is expected to drive a significant decrease in our near-term growth projections. We have reduced capacity in amounts and timing commensurate with the initially scheduled removal and inspection of these impacted engines; however, we continue to assess the impact on our future capacity plans. Pratt & Whitney stated that it is focused on addressing the challenges arising from the powdered metal manufacturing issue and will proactively take steps to support and mitigate the operational impact to its customers. We are in discussions with Pratt & Whitney regarding compensation for the loss of utilization; however, the amount, timing or structure of the compensation that will be agreed upon is not yet known.

Retirement of A319 Aircraft

We operate a single-fleet type of Airbus A320-family aircraft that is one of the youngest in the United States. During the fourth quarter of 2022, we made the decision to accelerate the retirement of 29 of our A319 aircraft. During the twelve months ended December 31, 2023, we completed the sale of 12 A319 airframes and 20 A319 engines. The remaining A319 aircraft had an average age of 16.9 years as of December 31, 2023. Excluding the A319 aircraft to be sold, the average age of our fleet would have been 5.5 years as of December 31, 2023. In addition, we are scheduled to take delivery of 121 new Airbus A320-family aircraft through 2029, potentially making ours the youngest fleet in the United States. Refer to “Notes to Consolidated Financial Statements— 1. Summary of Significant Accounting Policies" for additional information.

Summary Risk Factors

Our business is subject to a number of risks, including risks that may prevent us from achieving our business objectives or may adversely affect our business, financial condition, results of operations, cash flows and prospects. These risks are discussed more fully in Item 1A. Risk Factors herein. These risk factors include, but are not limited to, the following:

6

•The impact on our business of the Merger and our ability to complete the Merger in a timely manner;

•The competitiveness of our industry;

•Volatility in fuel costs or significant disruptions in the supply of fuel;

•Adverse domestic or global economic conditions on our business, results of operations and financial condition, including our ability to obtain financing or access capital markets;

•Factors beyond our control, including air traffic congestion at airports, air traffic control inefficiencies, major construction or improvements at airports, adverse weather conditions, increased security measures, new travel related taxes or the outbreak of disease;

•Increased labor costs, union disputes, employee strikes and other labor-related disruption;

•Our maintenance costs, which will increase as our fleet ages;

•The extensive regulation by the FAA, DOT, TSA and other U.S. and foreign governmental agencies to which we are subject;

•Our reliance on technology and automated systems to operate our business;

•Our reliance on third-party service providers to perform functions integral to our operations, including for ground handling, fuel, catering, passenger handling, maintenance, reservations and other services;

•Our reliance on a limited number of suppliers for our aircraft and engines;

•Reduction in demand for air transportation, or governmental reduction or limitation of operating capacity, in the domestic U.S., Caribbean or Latin American markets;

•The success of the Free Spirit Program and the Spirit Saver$ Club®; and

•Our significant amount of aircraft-related fixed obligations and additional debt that we have incurred, and may incur in the future.

Our Business Model

Our ULCC business model provides Guests low, unbundled base fares with a range of optional services, allowing Guests the freedom to choose only the options they value. The success of our model is driven by our low-cost structure, which has historically, up to 2020, allowed us to maintain high profit margins while offering low base fares. Our low-cost structure is primarily driven by having a high fleet utilization. Throughout most of 2023, we were unable to achieve historical high levels of fleet utilization primarily due to pilot and industry infrastructure constraints. In the post-pandemic period, lower utilization as well as wage and other inflationary pressures, have increased our operating costs. In addition, the industry has experienced capacity increases, leading to increased competition in the markets we serve and resulting in a decrease on our average fares.

We are focused on value-conscious travelers who pay for their own travel, and our business model is designed to deliver what our Guests want: low fares and a great experience. We use low fares to address underserved markets, which helps us to increase passenger volume and load factors on the flights we operate. We also have high-density seating configurations on our aircraft and a simplified onboard product designed to lower costs. High passenger volumes and load factors help increase our sales of ancillary products and services, which in turn allows us to reduce the base fare we offer even further. We strive to be recognized by our Guests and potential Guests as the low-fare leader in the markets we serve.

We compete based on total price. We believe that we and our Guests benefit when we allow our Guests to know the total price of their travel by breaking out the cost of optional products or services. We allow our Guests to see all available options and their respective prices prior to purchasing a ticket, and this full transparency illustrates that our total price, including the options selected is lower, on average, than other airlines.

Through branded campaigns, we educate the public on how our unbundled pricing model works, how it provides a choice on how they spend their money and how it saves them money compared to other airlines. We show our commitment to delivering the best value in the sky by continuing to make improvements to the Guest experience, including a freshly updated cabin interior with ergonomically-designed seats and self bag-tagging in most airports to reduce check-in processing time.

Our Strengths

We believe we compete successfully in the airline industry by leveraging the following demonstrated business strengths:

7

Ultra Low-Cost Structure. Our unit operating costs are among the lowest of all airlines operating in the United States. We believe this unit cost advantage helps protect our market position and enables us to offer some of the lowest base fares in our markets and support continued growth. Our operating costs per available seat mile ("CASM") of 10.52 cents in 2023 was significantly lower than those of the major domestic network carriers and among the lowest of the domestic low-cost carriers. We achieve these low unit operating costs in large part due to:

•high aircraft utilization;

•high-density seating configurations on our aircraft along with a simplified onboard product designed to lower costs;

•minimal hub-and-spoke network inefficiencies;

•highly productive workforce;

•opportunistic outsourcing of operating functions;

•operating a single-fleet type of Airbus A320-family aircraft that is one of the youngest and most fuel efficient in the United States and operated by common flight crews;

•reduced sales, marketing and distribution costs through direct-to-consumer marketing;

•efficient flight scheduling, including minimal ground times between flights; and

•a company-wide business culture that is keenly focused on driving costs lower.

Innovative Revenue Generation. We execute our innovative, unbundled pricing strategy to generate significant non-ticket revenue, which enables our passengers to identify, select and pay for only the products and services they want to use. In implementing our unbundled strategy, we have grown non-ticket revenue per passenger flight segment from approximately $5 in 2006 to $69 in 2023 generally by:

•charging for checked and carry-on baggage;

•passing through most distribution-related expenses;

•charging for premium seats and advance seat selection;

•applying dynamic pricing for ancillary products and services;

•maintaining consistent ticketing policies, including service charges for changes and cancellations;

•generating subscription revenue from our Spirit Saver$ Club®;

•deriving brand-based revenues from proprietary services, such as our Free Spirit affinity credit card program;

•offering a combination of our most popular Á La Smarte® items at a discount, such as boost-it and bundle-it combos;

•offering third-party travel products (travel packages), such as hotel rooms, ground transportation (rental and hotel shuttle products) and attractions (show or theme park tickets) packaged with air travel on our website; and

•selling third-party travel insurance through our website.

Our Network. We have developed a substantial network of destinations in U.S. domestic markets, targeted growth markets in the Caribbean and Latin America and high-volume routes flown by price-sensitive travelers. We seek to balance growth between large domestic markets, large leisure destinations and opportunities in the Caribbean and Latin America according to current economic and industry conditions.

Experienced International Operator. We believe we have substantial experience in foreign aviation, security and customs regulations, local ground operations and flight crew training required for successful international and overwater flight operations. All of our aircraft are certified for overwater operations. We believe we compete favorably against other low-cost carriers because we have been conducting international flight operations since 2003 and have developed substantial experience in complying with the various regulations and business practices in the international markets we serve. During 2023, 2022 and 2021, no revenue from any one foreign country represented greater than 4% of our total passenger revenue. We attribute operating revenues by geographic region based upon the origin and destination of each passenger flight segment.

Loyalty Programs

We operate the Spirit Saver$ Club®, which is a subscription-based loyalty program that allows members access to unpublished, extra-low fares as well as discounted prices on bags and seats, shortcut boarding and security, "Flight Flex" flight modification product, and exclusive offers on hotels, rental cars and other travel necessities. We also operate the Free Spirit

8

loyalty program (the “Free Spirit Program”), which attracts members and partners and builds customer loyalty for us by offering a variety of awards, benefits and services. Free Spirit Program members earn and accrue points for dollars spent on our flights and services from non-air partners such as retail merchants, hotels or car rental companies or by making purchases with credit cards issued by partner banks and financial services providers. Points earned and accrued by Free Spirit Program members can be redeemed for travel awards such as free (other than taxes and government-imposed fees), discounted or upgraded travel.

Route Network

During 2023, our route network included over 420 markets served by 93 airports throughout the United States, Latin America and the Caribbean. For more details on the destinations to which we fly, refer to our route map on our website, www.spirit.com/en/route-map.

Our network expansion targets underserved and/or overpriced markets. We employ a rigorous process to identify opportunities to deploy new aircraft where we believe they will be most profitable. To monitor the profitability of each route, we analyze weekly and monthly profitability reports as well as near-term forecasting.

Competition

The airline industry is highly competitive. The principal competitive factors in the airline industry are fare pricing, total price, flight schedules, aircraft type, passenger amenities, number of routes served from a city, customer service, safety record and reputation, code-sharing relationships and loyalty programs and redemption opportunities. We typically compete in markets served by traditional U.S. network airlines, and other low-cost carriers and ULCCs, and, to a lesser extent, regional airlines.

As of December 31, 2023, our top three largest network overlaps, as measured by overlapping available seat miles in metro markets, are with Southwest Airlines, American Airlines and Frontier Airlines. Our principal competitive advantage is our relative cost advantage which allows us to offer low base fares. In 2023, our unit operating costs were among the lowest in the U.S. airline industry. In most operating environments, we believe our low unit costs coupled with our relatively stable non-ticket revenues allow us to price our fares at levels where we can be profitable while our primary competitors cannot.

The airline industry is particularly susceptible to price discounting because, once a flight is scheduled, airlines incur only nominal incremental costs to provide service to passengers occupying otherwise unsold seats. The expenses of a scheduled aircraft flight do not vary significantly with the number of passengers carried and, as a result, a relatively small change in the number of passengers or in pricing could have a disproportionate effect on an airline’s operating and financial results. Price competition occurs on a market-by-market basis through price discounts, changes in pricing structures, fare matching, target promotions and loyalty initiatives. Airlines typically use discount fares and other promotions to stimulate traffic during normally slower travel periods to generate cash flow and to maximize TRASM. The prevalence of discount fares can be particularly acute when a competitor has excess capacity that it is unable to fill at higher rates. A key element to our competitive strategy is to maintain very low unit costs in order to permit us to compete successfully in price-sensitive markets.

Seasonality

Our business is subject to significant seasonal fluctuations. We generally expect demand to be greater in the second and third quarters each year due to more vacation travel during these periods, as compared to the rest of the year. The air transportation business is also volatile and highly affected by economic cycles and trends.

Distribution

The majority of our tickets are sold through direct channels, including online via www.spirit.com, our call center and our airport ticket counters, with www.spirit.com being the primary channel. We also partner with a number of third parties to distribute our tickets, including online and traditional travel agents and electronic global distribution systems.

Customers

We believe our customers are primarily leisure travelers who are paying for their own ticket and who make their purchase decision based largely on value. By maintaining a low-cost structure, we have historically been able to successfully sell tickets at lower fares while maintaining a strong profit margin. However, industry capacity increases have led to increased competition in the markets we serve and resulted in a decrease in our average fares.

Customer Service

We are committed to taking care of our customers. We believe focusing on customer service in every aspect of our operations, including personnel, flight equipment, in-flight and ancillary amenities, on-time performance, flight completion ratios, and baggage handling will strengthen customer loyalty and attract new customers. We proactively aim to improve our operations to ensure further improvement in customer service.

Our online booking process allows our customers to see all available options and their prices prior to purchasing a ticket. We maintain a campaign that illustrates our total prices are lower, on average, than those of our competitors, even when options are included.

Fleet

We fly only Airbus A320 family aircraft, which provides us significant operational and cost advantages compared to airlines that operate multiple aircraft types. By operating a single aircraft type, we avoid the incremental costs of training crews across multiple types. Flight crews are entirely interchangeable across all of our aircraft, and maintenance, spare parts inventories and other operational support remains highly simplified compared to those airlines with more complex fleets. Due to this commonality among Airbus single-aisle aircraft, we can retain the benefits of a fleet comprised of a single type of aircraft while still having the flexibility to match the capacity and range of the aircraft to the demands of each route.

As of December 31, 2023, we had a fleet of 205 Airbus single-aisle aircraft, which are commonly referred to as “A320 family” aircraft. A320 family aircraft include the A319, A320 and A321 models, which have broadly common design and equipment but differ most notably in fuselage length, service range and seat capacity. Within the A320 family of aircraft, models using existing engine technology may carry the suffix “ceo,” denoting the “current engine option,” while models equipped with new-generation engines may carry the suffix “neo,” denoting the “new engine option.” As of December 31, 2023, our fleet consisted of 19 A319ceos, 64 A320ceos, 84 A320neos, 30 A321ceos and 8 A321neos, and the average age of the fleet was 6.6 years. As of December 31, 2023, we owned 73 aircraft, of which 29 aircraft were financed through fixed-rate long-term debt, 27 aircraft were financed through enhanced equipment trust certificates ("EETCs") and 17 were purchased off lease. As of December 31, 2023, we had 132 leased aircraft, of which 117 aircraft were financed under operating leases and 15 aircraft would have been deemed finance leases resulting in failed sale-leaseback transactions. In addition, as of December 31, 2023, we had 6 spare engines financed under operating leases and owned 28 spare engines. Refer to “Notes to Consolidated Financial Statements—13. Debt and Other Obligations” and “Notes to Consolidated Financial Statements—14. Leases" for additional information.

On December 20, 2019, we entered into an A320 NEO Family Purchase Agreement with Airbus S.A.S. ("Airbus") for the purchase of 100 new Airbus A320neo family aircraft, with options to purchase up to 50 additional aircraft. This agreement included a mix of Airbus A319neo, A320neo and A321neo aircraft with such aircraft scheduled for delivery through 2027. As of December 31, 2023, our firm aircraft orders consisted of 99 A320 family aircraft with Airbus, including A320neos and A321neos, with deliveries expected through 2029. As of December 31, 2023, we had secured financing for 18 aircraft, scheduled for delivery from Airbus through 2025 which will be financed through sale-leaseback transactions. In addition, as of December 31, 2023, we had agreements in place for the delivery of 22 direct operating leases of A321neos with third-party lessors, expected through 2025.

During the third quarter of 2021, we entered into an Engine Purchase Support Agreement which requires us to purchase a certain number of spare engines in order to maintain a contractual ratio of spare engines to aircraft in the fleet. As of December 31, 2023, we are committed to purchase 19 PW1100G-JM spare engines, with deliveries through 2029. The firm aircraft orders provide for capacity growth as well as the flexibility to add to, or replace, the aircraft in our present fleet. We may elect to supplement these deliveries by additional acquisitions from the manufacturer or in the open market if demand conditions merit. We also may adjust or defer deliveries, or change models of aircraft in our delivery stream, from time to time, as a means to match our future capacity with anticipated demand and growth trends.

Consistent with our ULCC business model, each of our aircraft is configured with a high density seating configuration, which helps us maintain a lower unit cost. Our high density seating configuration accommodates more passengers than those of our competitors when comparing the same type of aircraft.

Maintenance and Repairs

We maintain our aircraft in accordance with an FAA-approved maintenance program built from the manufacturers recommended maintenance schedule and maintained by our Technical Services department. Our maintenance technicians undergo extensive initial and recurrent training to ensure the safe operation of our aircraft. For the sixth year in a row, Spirit has achieved the FAA’s highest award for Technical Training, the Diamond Award of Excellence. This award is only achieved if 100% of technicians receive the FAA’s Aircraft Maintenance Technician (“AMT”) Certificate of Training.

10

Aircraft maintenance and repair consists of routine and non-routine maintenance, and work performed is divided into three general categories: line maintenance, heavy maintenance and component service. Line maintenance consists of routine daily and weekly scheduled maintenance checks on our aircraft, including pre-flight, daily, weekly and overnight checks, and any diagnostics and routine repairs and any unscheduled items on an as needed basis. Additionally, maintenance program tasks that may take up to two years to fully complete are performed periodically in line maintenance at scheduled day visits or segmented into overnight work packages. Line maintenance events are currently serviced by in-house mechanics supplemented by contract labor and are primarily completed at airports we currently serve. Heavy airframe maintenance checks consist of a series of more complex tasks that generally can take from one to four weeks to accomplish and typically are required approximately every 36 months. Heavy engine maintenance is generally performed every six years and includes a more complex scope of work. Due to our relatively small fleet size and projected fleet growth, we believe outsourcing all of our heavy maintenance activity, such as engine servicing, heavy airframe maintenance checks, major part repair and component service repairs is more economical. Outsourcing eliminates the substantial initial capital requirements inherent in heavy aircraft maintenance. We have entered into a long-term flight hour agreement for the majority of our current fleet with International Aero Engines AG ("IAE") and Pratt & Whitney for our engine overhaul services and with various maintenance providers on an hour-by-hour basis for component services. We outsource our heavy airframe maintenance to FAA-qualified maintenance providers.

Our recent maintenance expenses have been lower than what we expect to incur in the future because of the relatively young age of our aircraft fleet. Our maintenance costs are expected to increase as the scope of repairs increases with the increasing age of our fleet. As our aircraft age, scheduled scope of work and frequency of unscheduled maintenance events is likely to increase like any maturing fleet. Our aircraft utilization rate could decrease with the increase in aircraft maintenance.

We own and operate a 126,000-square-foot maintenance hangar facility, adjacent to the airfield at the Detroit Metropolitan Wayne County Airport (DTW). In addition, we lease and operate a 63,700-square-foot maintenance hangar facility and 35,900-square-foot maintenance warehouse, adjacent to the airfield at the Houston George Bush Intercontinental Airport (IAH). These hangars and warehouse allow us to reduce our dependence on third-party facilities and contract line maintenance. Please see “Properties—Ground Facilities.”

Employees

Our business is labor intensive, with labor costs representing approximately 27.6%, 22.1% and 32.4% of our total operating costs for 2023, 2022 and 2021, respectively. As of December 31, 2023, we had 3,561 pilots, 6,208 flight attendants, 100 dispatchers, 366 ramp service agents, 284 passenger service agents, 685 aircraft maintenance technicians (a union contract with the Aircraft Mechanics Fraternal Association ("AMFA") is currently under negotiation) and 1,963 non-unionized personnel, airport agents/other and employees in administrative roles, for a total of 13,167 active employees compared to 12,025 active employees as of December 31, 2022. During the twelve months ended December 31, 2023, there were 2,345 employee terminations, including both voluntary and involuntary terminations, for an overall employee turnover rate of 19.5%. As of December 31, 2023, approximately 85% of our employees were represented by six labor unions. On an average full-time equivalent basis, for the full year 2023, we had 12,798 employees, compared to 12,102 in 2022.

FAA regulations require pilots to have commercial licenses with specific ratings for the aircraft to be flown and be medically certified as physically fit to fly. FAA and medical certifications are subject to periodic renewal requirements, including recurrent training and recent flying experience. Flight attendants must have initial and periodic competency training and qualification. For the year ended December 31, 2023, paid training hours for our pilots and flight attendants were 196,503 and 68,508 hours, representing 12.1% and 2.1% of total crew block hours, respectively. Mechanics, quality-control inspectors and dispatchers must be certificated and qualified for specific aircraft. Training programs are subject to approval and monitoring by the FAA. Management personnel directly involved in the supervision of flight operations, training, maintenance and aircraft inspection must also meet experience standards prescribed by FAA regulations. All safety-sensitive employees are subject to pre-employment, random and post-accident drug testing.

Consistent with our core values, we focus on hiring highly productive and qualified employees and ensure they have comprehensive training. Our training programs focus on and emphasize the importance of safety, customer service, productivity, and cost control. We provide continuous training for our crew members including technical training as well as regular training focused on safety and front-line training for our customer service teams. Our training programs include classroom learning, extensive real-world flying experience, and instruction in full flight simulators, as appropriate.

Our Diversity, Equity, Inclusion and Belonging ("DEI&B") journey began in 2020 with us listening, learning, and building awareness. By 2022, we had implemented a DEI&B governance structure and commitment, and had pivoted to a focus on meaningful impact. Our seven Team Member-run employee resource groups ensure all Team Members have a voice in

11

paving our path; our Supplier Diversity program ensures a focus on minority-owned business partners and diverse suppliers; and our activation plan ensures purposeful change, which includes a focus on Community Responsibility, Ensuring Equitable and Inclusive Total Rewards, Creating an Environment of Inclusion for All and Fostering Belonging Though Representation.

We believe a direct relationship between Team Members and our leadership is in the best interests of our crew members, our customers, and our shareholders. Our leadership team communicates on a regular basis with all Team Members, including crew members, in order to maintain a direct relationship and to keep them informed about news, strategy updates, and challenges affecting the airline and the industry. Effective and frequent communication throughout the organization is fostered through various means including email messages from our CEO and other senior leaders, open forum meetings across our network, periodic leadership visits to our stations, and annual Team Member engagement surveys. We also seek to build human rights awareness among our Team Members and Guests and we have recently implemented a Human Rights Policy.

The Railway Labor Act, or RLA, governs our relations with labor organizations. Under the RLA, our collective bargaining agreements (CBAs) do not expire, but instead become amendable as of a stated date, subject to standard early opener provisions. If either party wishes to modify the terms of any such agreement, they must notify the other party in the manner agreed to by the parties. Under the RLA, after receipt of such notice, the parties must meet for direct negotiations. If no agreement is reached, either party may request the National Mediation Board, or NMB, appoint a federal mediator. The RLA prescribes no set timetable for the direct negotiation and mediation process. It is not unusual for those processes to last for many months, and even several years. If no agreement is reached in mediation, the NMB in its discretion may declare at some time that an impasse exists. If an impasse is declared, the NMB proffers binding arbitration to the parties. Either party may decline to submit to arbitration. If arbitration is rejected by either party, a 30-day “cooling off” period commences. During that period (or after), a Presidential Emergency Board, or PEB, may be established, which examines the parties’ positions and recommends a solution. The PEB process lasts for 30 days and is followed by another “cooling off” period of 30 days. At the end of the “cooling off” periods, unless an agreement is reached or action is taken by Congress, the labor organization and the airline each may resort to “self-help,” including, for the labor organization, a strike or other labor action, and for the airline, the imposition of any or all of its proposed amendments and the hiring of new employees to replace any striking workers. Congress and the President have the authority to prevent “self-help” by enacting legislation that, among other things, imposes a settlement on the parties. The table below sets forth our employee groups and status of their collective bargaining agreements.

Employee Groups	Representative	Amendable Date (1)
Pilots	Air Line Pilots Association, International (ALPA)	January 2025
Flight Attendants	Association of Flight Attendants (AFA-CWA)	January 2026
Dispatchers	Professional Airline Flight Control Association (PAFCA)	October 2023
Ramp Service Agents	International Association of Machinists and Aerospace Workers (IAMAW)	November 2026
Passenger Service Agents	Transport Workers Union of America (TWU)	February 2027

(1) Subject to standard early opener provisions.

(2) Collective bargaining agreement is currently under negotiation.

During the fourth quarter of 2022, we reached an agreement with ALPA for a new two-year agreement, which was ratified by ALPA members on January 10, 2023. The ratified agreement includes increased pay rates and other enhanced benefits.

In February 2021, we entered into a Letter of Agreement with the AFA-CWA to change the amendable date of the collective bargaining agreement from May 4, 2021 to September 1, 2021. All other terms of the collective bargaining agreement remained the same. In June 2021, the AFA-CWA notified us, as required by the RLA, that it intended to submit proposed changes to the collective bargaining agreement covering our flight attendants. We commenced negotiations with the AFA-CWA on September 27, 2021. In February 2023, we reached an agreement with our flight attendants which was ratified by the flight attendants on April 13, 2023 and becomes amendable in January 2026. The ratified agreement includes increased pay rates and other enhanced benefits.

Our dispatchers are represented by PAFCA. In October 2018, we reached a tentative agreement with PAFCA for a new five-year agreement, which was ratified by the PAFCA members in October 2018. In May 2023, PAFCA provided notice that it

12

intends to amend its Collective Bargaining Agreement with our dispatchers. The parties began negotiating changes to the CBA on July 12, 2023. As of December 31, 2023, we continued to negotiate with PAFCA.

Our ramp service agents are represented by IAMAW. Representation only applies to our Fort Lauderdale station where we have direct employees in the ramp service agent classification. In February 2020, the IAMAW notified us, as required by the RLA, that it intended to submit proposed changes to the collective bargaining agreement covering our ramp service agents which became amendable in June 2020. On September 28, 2021, we filed an “Application for Mediation Services” with the NMB. We were able to reach a tentative agreement with the IAMAW with the assistance of the NMB on October 16, 2021. Our ramp service agents ratified the five-year agreement in November 2021.

In June 2018, our passenger service agents voted to be represented by the TWU, but the representation only applies to our Fort Lauderdale station where we have direct employees in the passenger service classification. We began meeting with the TWU in late October 2018 to negotiate an initial collective bargaining agreement. During February 2022, we reached a tentative agreement with the TWU. Our passenger service agents ratified the five-year agreement on February 21, 2022.

In August 2022, our aircraft maintenance technicians ("AMTs") voted to be represented by AMFA as their collective bargaining agent. As of December 31, 2023, we employed approximately 700 AMTs. In November 2022, AMFA notified us of its intent to negotiate a CBA and began negotiations. In October 2023, AMFA filed for mediation with the NMB, and we are currently waiting for mediation dates from the NMB to continue negotiating with AMFA.

Safety and Security

We are committed to the safety and security of our passengers and employees. We strive to comply with or exceed health and safety regulation standards. In pursuing these goals, we maintain an active aviation safety program. All of our personnel are expected to participate in the program and take an active role in the identification, reduction and elimination of hazards.

Our ongoing focus on safety relies on training our employees to proper standards and providing them with the tools and equipment they require so they can perform their job functions in a safe and efficient manner. Safety in the workplace targets several areas of our business, including: flight operations, maintenance, in-flight, dispatch and station operations. The Transportation Security Administration, or TSA, is charged with aviation security for both airlines and airports. We maintain active, open lines of communication with the TSA at all of our locations to ensure proper standards for security of our personnel, customers, equipment and facilities are exercised throughout our business.

Insurance

We maintain insurance policies we believe are customary in the airline industry and as required by the DOT. The policies principally provide liability coverage for public and passenger injury; damage to property; loss of or damage to flight equipment; fire and extended coverage; war risk (terrorism); directors’ and officers’ liability; advertiser and media liability; cyber risk liability; fiduciary; and workers’ compensation and employer’s liability. Renewing coverage could result in a change in premium and more restrictive terms. Although we currently believe our insurance coverage is adequate, there can be no assurance that the amount of such coverage will not be changed or that we will not be forced to bear substantial losses from accidents.

Management Information Systems

We have continued our commitment to technology improvements to support our ongoing operations and initiatives. In 2021, we focused on additional modernization capabilities to enhance the travel experience of our Guests. In cooperation with the TSA, our Automated Self Service Bag Drop project is installed and functioning in several airports. Our plan is to accelerate the deployment of this experience as well as to further enhance the customer convenience features. In addition, we have achieved a broad investment in a mobility tool for all our workforce that enhances productivity and capabilities. Furthermore, we believe the launch of our new Free Spirit Program has delivered an exceptional improvement in the Guest experience and utility. In 2021, the Azure Cloud migration of Data and Application continued. Lastly, our secondary Operations Control Center in Orlando went into production mid-year and will provide substantial improvements in disaster recovery scenarios.

In 2022, we targeted the modernization of our crew applications and technologies to accelerate the response to irregular operations. These improvements involved upgrades to the main flight operations system, enabling and enhancing chat functionality for our crews, improving crew scheduling voice response, and providing real time operational monitoring capabilities. In addition to operations, we have made significant improvements to our digital transformation for Guest experience through the implementation of our customer data platform. We have successfully migrated our maintenance and flight operation systems to the Azure cloud. Our journey to full cloud continues as we continue to seek opportunities to optimize cloud solutions.

13

In 2023, we continued our technology modernization with a new mobile workplace application for the Flight Attendant team. This application improves the experience for streamlining daily tasks such as check-in, assigning positions, viewing manifests and personal work schedules. Our digital transformation journey added capabilities providing self-service options to our Guests and employees such as refund automation, flight status, employee benefits and more. This year we matured our cyber security programs within the CIS v8 framework as we refine our environments to meet the rapidly changing cyber threat landscape. One major focus has been providing a more frequent cycle of timely and consistent cyber security awareness to our team members. The cloud strategy continues to evolve as operational and cyber security imperatives guide us, migration of services and data continues in our multi-region footprint and we have begun planning for a diverse cloud provider strategy.

Foreign Ownership

Under DOT regulations and federal law, we must be owned and controlled by U.S. citizens. In order to qualify, at least 75% of our stock must be voted by U.S. citizens, 51% of our outstanding equity must be owned by U.S. citizens, and our president and at least two-thirds of our board of directors and senior management must be U.S. citizens.

We believe we are currently in compliance with such foreign ownership rules.

Government Regulation

Operational Regulation

The airline industry is heavily regulated, especially by the federal government. Two of the primary regulatory authorities overseeing air transportation in the United States are the DOT and the FAA. The DOT has jurisdiction over economic and consumer issues affecting air transportation, such as competition, route authorizations, advertising and sales practices, baggage liability, disabled passenger transportation, reporting of mishandled bags, tarmac delays and responding to customer complaints among other areas.

In July 2021, the DOT issued a Notice of Proposed Rulemaking (NRPM) requiring airlines to refund checked bag fees for delayed bags if they are not delivered to the passenger within a specified number of hours and refunding ancillary fees for services related to air travel that passengers did not receive.

In November 2021, the DOT reopened the comment period on an NPRM regarding short-term improvements to lavatory accessibility, including new proposed requirements for onboard wheelchairs (OBWs) (Part 1). This NPRM was to gather information about all aspects of OBW design, including stowage, before issuing any final binding regulation on the topic.

In March 2022, the DOT issued a NPRM (Part 2) requiring airlines to ensure that at least one lavatory on new single-aisle aircraft with at least 125 passenger seats is large enough to permit a passenger with a disability (with the help of an assistant, if necessary) to approach, enter and maneuver within the lavatory, as necessary, to use all lavatory facilities and to leave by means of the aircraft’s on-board wheel chair. If enacted as currently proposed, this NPRM (Part 2) would apply to new aircraft ordered 18 years or delivered 20 years after the effective date of a final rule. The DOT published its Accessible Lavatories on Single-Aisle Aircraft final rule on August 1, 2023, which became effective October 2, 2023. Among other requirements, the final rule requires new single-aisle aircraft with 125 seats or more that are ordered 10 years after or delivered 12 years after October 2, 2023, to have accessible lavatories.

In July 2022, the DOT published its Airline Passengers with Disabilities Bill of Rights, applicable to U.S. and foreign carriers, and required airlines to publish the same on their websites with appropriate email notifications sent to passengers with disabilities. The DOT continues to review potential rules regarding disabled passengers, including a NPRM scheduled to be released next year regarding wheelchair handling and training initiatives.

In July 2022, the Office of Aviation Consumer Protection (OACP) issued a notice urging airlines to provide seats to children 13 years or younger with an adult on the same booking with no additional charge. In response to the OACP’s notice during 2023, the DOT added to their website a Child Seating dashboard comparing reporting carriers and their procedures on seating children 13 years or younger with an adult on a booking.

In August 2022, the DOT issued a NPRM requiring airlines and ticket agents to provide non-expiring travel vouchers or credits to consumers holding non-refundable tickets for scheduled flights to, from, or within the United States as a result of the carrier cancelling or making a significant change to a scheduled flight, a serious communicable disease or for several other reasons. The NPRM will further define the terms “significant change” and “cancellation” and will require airlines and ticket agents to provide refunds if they receive significant financial assistance from the government as a result of a public health

14

emergency. As of December 31, 2023, a final rule has not been issued; however, it is our understanding that the DOT will combine this NPRM with the July 2021 PRM, regarding refunding of certain checked bag fees and ancillary fees, and that the DOT anticipates issuing a final rule in February 2024.

At the end of August 2022, the DOT added an Airline Customer Service Dashboard to their website that compares what reporting carriers offer passengers during a significant controllable delay or cancellation.

In October 2022, the DOT issued a NRPM which would require airlines to increase disclosure of bag fees, change and cancellation fees, and family seating policies during the ticket purchase process in an effort to improve the transparency of airline pricing. The comment period closed on January 23, 2023. The DOT is expected to issue its final rule on fee disclosures in March 2024.

Additional rules and executive orders, including those pertaining to disabled passengers, may be issued. See “Risk Factors—Risks Related to Our Industry—Restrictions on, or increased taxes applicable to, charges for ancillary products and services paid by airline passengers and burdensome consumer protection regulations or laws could harm our business, results of operations and financial condition.”

The DOT has authority to issue certificates of public convenience and necessity required for airlines to provide air transportation. We hold a DOT certificate of public convenience and necessity authorizing us to engage in scheduled air transportation of passengers, property and mail within the United States, its territories and possessions and between the United States and all countries that maintain a liberal aviation trade relationship with the United States (known as “open skies” countries). We also hold DOT certificates to engage in air transportation to certain other countries with more restrictive aviation policies.

The FAA is responsible for regulating and overseeing matters relating to air carrier flight operations, including airline operating certificates, aircraft certification and maintenance and other matters affecting air safety, including rest periods and work hours for all airlines certificated under Part 121 of the Federal Aviation Regulations. The FAA requires each commercial airline to obtain and hold an FAA air carrier certificate. This certificate, in combination with operations specifications issued to the airline by the FAA, authorizes the airline to operate at specific airports using aircraft approved by the FAA. As of December 31, 2023, we had FAA airworthiness certificates for all of our aircraft, we had obtained the necessary FAA authority to fly to all of the cities we currently serve, and all of our aircraft had been certified for overwater operations. Any new or revised operational regulations in the future could result in further increased costs. We believe we hold all necessary operating and airworthiness authorizations, certificates and licenses and are operating in compliance with applicable DOT and FAA regulations, interpretations and policies.

On June 6, 2023, the FAA issued a final rule which requires aircraft manufactured two years after August 25, 2023, which are operated in domestic commercial service by Part 121 airlines to have an installed physical secondary barrier that protects the flightdeck from unauthorized intrusion when the flightdeck door is opened. We are currently evaluating the impacts, if any, of the ruling, which we do not expect to be material.

International Regulation

All international service is subject to the regulatory requirements of the foreign government involved. We generally offer international service to Aruba, Colombia, Costa Rica, Dominican Republic, Ecuador, El Salvador, Guatemala, Haiti, Honduras, Jamaica, Mexico, Nicaragua, Peru and St. Maarten, as well as Puerto Rico and the U.S. Virgin Islands. If we decide to increase our routes to additional international destinations, we will be required to obtain necessary authority from the DOT and the applicable foreign government. We are also required to comply with overfly regulations in countries that lay along our routes but which we do not serve.

International service is also subject to Customs and Border Protection, or CBP, immigration and agriculture requirements and the requirements of equivalent foreign governmental agencies. Like other airlines flying international routes, from time to time we may be subject to civil fines and penalties imposed by CBP if unmanifested or illegal cargo, such as illegal narcotics, is found on our aircraft. These fines and penalties, which in the case of narcotics are based upon the retail value of the seizure, may be substantial. We have implemented a comprehensive security program at our airports to reduce the risk of illegal cargo being placed on our aircraft, and we seek to cooperate actively with CBP and other U.S. and foreign law enforcement agencies in investigating incidents or attempts to introduce illegal cargo.

We will continue to comply with all contagious disease requirements issued by the US and foreign governments, but we cannot forecast what additional requirements may be imposed in the future or the costs or revenue impact that would be associated with complying with such requirements. See, “Risk Factors—Risks Related to Our Business—We are subject to

15

extensive and increasing regulation by the FAA, DOT, TSA and other U.S. and foreign governmental agencies, compliance with which could cause us to incur increased costs and adversely affect our business and financial results.”

Security Regulation

The TSA was created in 2001 with the responsibility and authority to oversee the implementation, and ensure the adequacy of security measures at airports and other transportation facilities. Funding for passenger security is provided in part by a per enplanement ticket tax (passenger security fee); which as of December 19, 2014, was limited to a round-trip fee of $11.20. We cannot forecast what additional security and safety requirements may be imposed in the future or the costs or revenue impact that would be associated with complying with such requirements.

Environmental Regulation

We are subject to various federal, state and local laws and regulations relating to the protection of the environment and affecting matters such as aircraft engine emissions, aircraft noise emissions and the discharge or disposal of materials and chemicals, which laws and regulations are administered by numerous state and federal agencies. The Environmental Protection Agency, or EPA, regulates operations, including air carrier operations, which affect the quality of air in the United States. We believe the aircraft in our fleet meet all emission standards issued by the EPA. Concern about climate change and greenhouse gases may result in additional regulation or taxation of aircraft emissions in the United States and abroad.

Federal law recognizes the right of airport operators with special noise problems to implement local noise abatement procedures so long as those procedures do not interfere unreasonably with interstate and foreign commerce and the national air transportation system. These restrictions can include limiting nighttime operations, directing specific aircraft operational procedures during takeoff and initial climb, and limiting the overall number of flights at an airport.

Other Regulations

We are subject to certain provisions of the Communications Act of 1934, as amended, and are required to obtain an aeronautical radio license from the Federal Communications Commission, or FCC. To the extent we are subject to FCC requirements, we will take all necessary steps to comply with those requirements. We are also subject to state and local laws and regulations at locations where we operate and the regulations of various local authorities that operate the airports we serve. In addition, we are subject to the deployment of new 5G C-band service by wireless communications providers. The DOT and the FAA are currently working with AT&T and Verizon to create appropriate safeguards in the deployment of their new 5G C-band service, which includes the installation of buffer zones around airports and other measures. The DOT and the FAA have required that all U.S. based carriers have 5G C-Band-tolerant radio altimeters or install approved filters by February 2024.

Future Regulations

The U.S. and foreign governments may consider and adopt new laws, regulations, interpretations and policies regarding a wide variety of matters that could directly or indirectly affect our results of operations. We cannot predict what laws, regulations, interpretations and policies might be considered in the future, nor can we judge what impact, if any, the implementation of any of these proposals or changes might have on our business.

Corporate Responsibility and Sustainability

We are committed to integrating environmental, social and governance (“ESG”) practices into and within our business practices and commit to sustainable operations which support the long-term success of our business, shareholders, Team Members, Guests and business partners. We have established four strategic focus areas of our ESG initiatives, practices and commitments: environment, social, workforce and governance. Recognizing the fundamental importance of ESG matters, Spirit’s Board and its committees provide guidance and oversight. The Nominating and Corporate Governance Committee is responsible for oversight of our ESG strategy and practices and periodically reports on these matters to the Board.

We recognize aviation’s impact on climate and our responsibility to help reduce the carbon footprint of air travel. Fuel burn is our greatest environmental and financial impact, and our greatest source of carbon emissions. To address the impact of our flights and operations over the short-term and long-term, our climate and emissions approach focuses on reducing emissions through both fleet and operational efficiencies that conserve fuel and improve overall fuel burn. Our all-Airbus fleet is one of the youngest in the United States and our dense seating configuration, along with our consistent focus on weight-saving measures, has made us consistently one of the most fuel-efficient carriers in the United States.

Further illustrating our commitment, during the fourth quarter of 2023, we issued our 2021/2022 Sustainability Report, showing results of our longstanding commitment to meaningful advancements in environmental sustainability, Guest and community service, Team Member support, and governance. The report highlights our plan for continued progress in

16

broadening ESG initiatives and improving communities. Refer to “Spirit’s 2021/2022 Sustainability Report” on the Investor Relations section of our website at www.spirit.com.

Risks Related to Recent Events

The pendency of the proposed Merger may cause disruption in our business.

On July 28, 2022, we entered into the Merger Agreement with JetBlue and Merger Sub, pursuant to which and subject to the terms and conditions therein, Merger Sub will merge with and into Spirit, with Spirit continuing as the surviving entity.

On March 7, 2023, the DOJ filed suit to block the Merger and a trial was held in late 2023. On January 16, 2024, the District Court granted the Injunction. On January 19, 2024, Spirit and JetBlue filed a notice of appeal to reverse the Injunction and allow Spirit and JetBlue to complete the Merger. On January 25, 2024, JetBlue informed us that certain closing conditions required by the Merger Agreement may not be satisfied prior to the outside dates set forth in the Merger Agreement and, accordingly, the Merger Agreement may be terminable on and after January 28, 2024. We do not believe there is a basis for terminating the Merger Agreement, and we will continue to abide by all of our obligations under the Merger Agreement. On January 29, 2024, Spirit and JetBlue filed a request with the Court of Appeals seeking an expedited hearing of their appeal of the Injunction. On February 2, 2024, the Court of Appeals granted our motion, stating it would hear arguments in June 2024.

The Merger Agreement restricts us from taking specified actions without JetBlue’s consent until the Merger is completed or the Merger Agreement is terminated, including amending our organizational documents, issuing shares of our common stock, divesting certain assets (including certain intellectual property rights), declaring or paying dividends, making certain significant acquisitions or investments, entering into any new lines of business, incurring certain indebtedness in excess of certain thresholds, amending or modifying certain material contracts, making non-ordinary course capital expenditures, making certain non-ordinary course changes to personnel and employee compensation, changing the cabin configuration or amenities on our aircraft and taking actions that may result in the loss of our FAA airworthiness certification or takeoff and landing slots. These restrictions and others more fully described in the Merger Agreement may affect our ability to execute our business strategies and attain our financial and other goals and may impact our business, results of operations and financial condition.

The pendency of the proposed Merger could cause disruptions to our business or business relationships, which could have an adverse impact on our results of operations. Parties with which we have business relationships, including Guests, pilots, employees, suppliers, third-party service providers and third-party distribution channels, may be uncertain as to the future of such relationships and may delay or defer certain business decisions, seek alternative relationships with third parties or seek to alter their present business relationships with us. Parties with whom we otherwise may have sought to establish business relationships may seek alternative relationships with third parties.

18

The pursuit of the Merger and the preparation for our integration with JetBlue’s business is expected to place a significant burden on our management and internal resources. The diversion of management’s attention away from day-to-day business concerns and any difficulties encountered in the transition and integration process could adversely affect our business, results of operations and financial condition.

We have incurred and will continue to incur significant costs, expenses and fees for professional services and other transaction costs in connection with the Merger. The substantial majority of these costs will be non-recurring expenses relating to the Merger, and many of these costs are payable regardless of whether or not the Merger is consummated. We also have been subject to, and may face additional, litigation related to the proposed Merger, which could prevent or delay the consummation of the Merger and result in significant costs and expenses.

Failure to complete the Merger in a timely manner or at all could negatively impact the market price of our common stock, as well as our future business and our results of operations and financial condition.

The Merger cannot be completed until conditions to closing are satisfied or (if permissible under applicable law) waived. The Merger is subject to numerous closing conditions, including among other things, (1) approval of the transactions by our stockholders (which was received on October 19, 2022); (2) receipt of applicable regulatory approvals, including approvals from the FCC, FAA and DOT and the expiration or early termination of the statutory waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and other competition laws, and other required regulatory approvals; (3) the absence of any law or order prohibiting the consummation of the transactions; and (4) the absence of any material adverse effect (as defined in the Merger Agreement) on the Company.

The failure to satisfy the required conditions could delay the completion of the Merger for a significant period of time or prevent it from occurring. There can be no assurance that the conditions to the closing of the Merger will be satisfied or waived, that our appeal of the District Court's decision will be successful or that the Merger will be completed.

Following the Injunction, and in the event the Merger is not completed in a timely manner or at all, our ongoing business may be adversely affected as follows:

•we have experienced and continue to experience negative reactions from the financial markets, and our stock price has declined and could continue to decline to the extent that the current market price reflects an assumption that the Merger will be completed;

•we may experience negative reactions from employees, Guests, suppliers or other third parties;

•we may be subject to litigation, which could result in significant costs and expenses;

•management’s focus may be diverted from day-to-day business operations and from pursuing other opportunities that could have been beneficial to the Company; and

•our costs of pursuing the Merger may be higher than anticipated.

Additionally, in approving the Merger Agreement, the Board of Directors considered a number of factors and potential benefits, including the fact that the merger consideration to be received by holders of common stock represented a significant premium over the last closing stock price prior to announcement of the Merger. If the Merger is not completed, the holders of our common stock will not realize this benefit of the Merger.

In addition to the above risks, we may be required, under certain circumstances, to pay JetBlue a breakup fee equal to $94.2 million and/or to reimburse or indemnify JetBlue for certain of its expenses. If the Merger is not consummated due to the inability to receive regulatory approval, JetBlue would be required to pay Spirit a reverse termination fee of $70 million. The reverse termination fee may not be sufficient to cover all of the expenses Spirit incurred in connection with the Merger, which may have an adverse effect on our liquidity and results of operations. If the Merger is not consummated, there can be no assurance that these risks will not materialize and will not materially adversely affect our stock price, business, results of operations and financial condition.

In order to complete the Merger, the Company and JetBlue must obtain certain governmental approvals, and if such approvals are not granted or are granted with conditions, completion of the Merger may be jeopardized or the anticipated benefits of the Merger could be reduced.

19

Although the Company and JetBlue have agreed to use reasonable best efforts, subject to certain limitations, to make certain governmental filings and obtain the required governmental approvals, including from the FCC, FAA and DOT, or expiration or earlier termination of relevant waiting periods, as the case may be, there can be no assurance that the relevant waiting periods will expire or be terminated or that the relevant approvals will be obtained. As a condition to approving the Merger, these governmental authorities may impose conditions, terms, obligations or restrictions or require divestitures or place restrictions on the conduct of the combined company's business after completion of the Merger. There can be no assurance that regulators will not impose conditions, terms, obligations or restrictions and that such conditions, terms, obligations or restrictions will not have the effect of delaying or preventing completion of the Merger or imposing additional material costs on or materially limiting the revenues of the combined company following the Merger, or otherwise adversely affecting, including to a material extent, our business, results of operations and financial condition after completion of the Merger. If we are required to divest assets or businesses, there can be no assurance that we will be able to negotiate such divestitures expeditiously or on favorable terms or that the governmental authorities will approve the terms of such divestitures. We can provide no assurance that these conditions, terms, obligations or restrictions will not result in the abandonment of the Merger.

On March 7, 2023, the DOJ filed suit to block the Merger. A trial was held in late 2023. On January 16, 2024, the District Court granted the Injunction. On January 19, 2024, Spirit and JetBlue filed a notice of appeal to reverse the District Court's decision and allow Spirit and JetBlue to complete the Merger. On January 29, 2024, Spirit and JetBlue filed a request with the Court of Appeals seeking an expedited schedule for their appeal. On February 2, 2024, the Court of Appeals granted our motion, stating it would hear arguments in June 2024. The appeal of the Injunction will be time-consuming and expensive and there can be no assurance that we or JetBlue would ultimately be successful, or that if the Injunction is reversed, that the DOJ would not further appeal. Furthermore, any of the other governmental authorities from which we need approvals may also sue us and JetBlue in U.S. federal court to prevent the Merger from being consummated. Defending any such lawsuit will be time-consuming and expensive and there can be no assurance that we and JetBlue would ultimately be successful.

Additionally, if the Merger is not consummated, Spirit stockholders and holders of Spirit's convertible notes and warrants will not receive the merger consideration that would have been paid at the closing of the Merger.

You must be a Spirit stockholder as of the specified record dates to receive the prepayments of merger consideration.

The prepayments of merger consideration by JetBlue will only be made to Spirit stockholders as of the specified record dates. If you are not a Spirit stockholder as of that record date, you will not receive the relevant prepayment even if you are a Spirit stockholder at the time of consummation of the Merger. As a result, if you are not a Spirit stockholder at each relevant time, you will receive less than $33.50 (or less than the up to $34.15 maximum amount of merger consideration, depending on the timing of Closing) in total for each share of Spirit common stock you own upon the consummation of the Merger.

Risks Related to Our Industry

We operate in an extremely competitive industry.

We face significant competition with respect to routes, fares and services. Within the airline industry, we compete with traditional network airlines, other low-cost airlines and regional airlines on many of our routes. Competition in most of the destinations we presently serve is intense, sometimes due to the large number of carriers in those markets. Furthermore, other airlines may begin service or increase existing service on routes where we currently face little competition. Most of our competitors are larger than us and have significantly greater financial and other resources than we do.

The airline industry is particularly susceptible to price discounting because once a flight is scheduled, airlines incur only nominal additional costs to provide service to passengers occupying otherwise unsold seats. Increased fare or other price competition has adversely affected, and may continue to adversely affect, our revenue generation. Moreover, many other airlines have begun to unbundle services by charging separately for services such as baggage and advance seat selection. This unbundling and other cost reducing measures could enable competitor airlines to reduce fares on routes that we serve. Beginning in 2015, and continuing through 2019, more widespread availability of low fares, including from legacy network carriers, coupled with an increase in domestic capacity led to dramatic changes in pricing behavior in many U.S. markets. Many domestic carriers began matching lower cost airline pricing, either with limited or unlimited inventory. Additionally, changes in practices, including with respect to change and cancellation fees, as a result of the COVID-19 pandemic has led to further pricing changes among our competitors.

20

Airlines increase or decrease capacity in markets based on perceived profitability, market share objectives, competitive considerations and other reasons. Decisions by our competitors that increase overall industry capacity, or capacity dedicated to a particular domestic or foreign region, market or route, could have a material adverse impact on our business. If a traditional network airline were to successfully develop a low-cost structure, compete with us on price or if we were to experience increased competition from other low-cost carriers, our business could be materially adversely affected.

Many of the traditional network airlines in the United States have on one or more occasions initiated bankruptcy proceedings in attempts to restructure their debt and other obligations and reduce their operating costs. They also have completed large mergers that have increased their scale and share of the travel market. The mergers between AMR Corporation and US Airways Group, Inc., between Delta Air Lines and Northwest Airlines, between United Airlines and Continental Airlines, between Southwest Airlines and AirTran Airways, and between Alaska Airlines and Virgin America, have created five large airlines, with substantial national and international networks which create a more challenging competitive environment for smaller airlines like us. In the future, there may be additional consolidation in our industry. For example, on December 3, 2023, Alaska Airlines and Hawaiian Airlines announced a proposed merger. Any business combination could significantly alter industry conditions and competition within the airline industry, which could have an adverse effect on our business.

Our growth and the success of our ULCC business model could stimulate competition in our markets through our competitors’ development of their own ULCC strategies, new pricing policies designed to compete with ULCCs or new market entrants. Any such competitor may have greater financial resources and access to less expensive sources of capital than we do, which could enable them to operate their business with a lower cost structure, or enable them to operate with lower marginal revenues without substantial adverse effects, than we can. If these competitors adopt and successfully execute a ULCC business model, we could be materially adversely affected. In 2015, Delta Air Lines began to market and sell a “Basic Economy” product which was designed in part to provide its customers with a low base fare similar to Spirit. In 2017, American Airlines and United Airlines announced their own “Basic Economy” product and beginning in late 2019, other airlines like Alaska Airlines and JetBlue, have followed suit.

The extremely competitive nature of the airline industry could prevent us from attaining the level of passenger traffic or maintaining the level of fares or revenues related to ancillary services required to sustain profitable operations in new and existing markets and could impede our growth strategy, which could harm our operating results. Due to our relatively small size, we are susceptible to a fare war or other competitive activities in one or more of the markets we serve, which could have a material adverse effect on our business, results of operations and financial condition.

Our low-cost structure is one of our primary competitive advantages, and many factors could affect our ability to control our costs.

Our low-cost structure is one of our primary competitive advantages. However, we have limited control over many of our costs. For example, we have limited control over the price and availability of aircraft fuel, aviation insurance, airport costs and related infrastructure taxes, the cost of meeting changing regulatory requirements and our cost to access capital or financing. In addition, the compensation and benefit costs applicable to a significant portion of our employees are established by the terms of our collective bargaining agreements. We cannot guarantee we will be able to maintain a cost advantage over our competitors. If our cost structure increases and we are no longer able to maintain a sufficient cost advantage over our competitors, it could have a material adverse effect on our business, results of operations and financial condition.

The airline industry is heavily influenced by the price and availability of aircraft fuel. Continued volatility in fuel costs or significant disruptions in the supply of fuel, including hurricanes and other events affecting the Gulf Coast in particular, could materially adversely affect our business, results of operations and financial condition.

Aircraft fuel costs represented 31.1%, 34.1% and 27.8% of our total operating expenses for 2023, 2022 and 2021, respectively. As such, our operating results are significantly affected by changes in the availability and the cost of aircraft fuel, especially aircraft fuel refined in the U.S. Gulf Coast region, on which we are highly dependent. Both the cost and the availability of aircraft fuel are subject to many meteorological, economic and political factors and events occurring throughout the world, which we can neither control nor accurately predict. For example, a major hurricane making landfall along the Gulf Coast could disrupt oil production, refinery operations and pipeline capacity in that region, possibly resulting in significant increases in the price of aircraft fuel and diminished availability of aircraft fuel supply. Any disruption to oil production, refinery operations, or pipeline capacity in the Gulf Coast region could have a disproportionate impact on our operating results compared to other airlines that have more diversified fuel sources. Fuel prices also may be affected by geopolitical and macroeconomic conditions and events that are outside of our control, including volatility in the relative strength of the U.S. dollar, the currency in which oil is denominated. Instability within major oil producing regions, such as the Middle East and Venezuela, Russia's ongoing conflict in Ukraine, the conflict in Gaza, changes in demand from major petroleum users such as China, and secular increases in competing energy sources are examples of these trends.

21

Aircraft fuel prices have been subject to high volatility, fluctuating substantially over the past several years. For example, our fuel prices spiked at a high of $3.82 per gallon, in the third quarter of 2022, and fell as low as $1.05 per gallon in the second quarter of 2020. We cannot predict the future availability, price volatility or cost of aircraft fuel. Due to the large proportion of aircraft fuel costs in our total operating cost base, even a relatively small increase or decrease in the price of aircraft fuel can have a significant negative impact on our operating costs or revenues and on our business, results of operations and financial condition.

Fuel derivative activity, if any, may not reduce fuel costs.

From time to time, we may enter into fuel derivative contracts in order to mitigate the risk to our business from future volatility in fuel prices, refining risk between the price of crude oil and the price of refined jet fuel, and to manage the risk of increasing fuel prices. Our derivatives may generally consist of United States Gulf Coast jet fuel swaps (“jet fuel swaps”) and United States Gulf Coast jet fuel options (“jet fuel options”). Both jet fuel swaps and jet fuel options can be used at times to protect the refining risk between the price of crude oil and the price of refined jet fuel, and to manage the risk of increasing fuel prices. As of December 31, 2023, we had no outstanding jet fuel derivatives, and we have not engaged in fuel derivative activity since 2015. There can be no assurance that we will be able to enter into fuel derivative contracts in the future if we are required or choose to do so. In the past we have not had, and in the future we may not have, sufficient creditworthiness or liquidity to post the collateral necessary to hedge our fuel requirements. Our liquidity and general level of capital resources impacts our ability to hedge our fuel requirements. Even if we are able to hedge portions of our future fuel requirements, we cannot guarantee that our derivative contracts will provide sufficient protection against increased fuel costs or that our counterparties will be able to perform under our derivative contracts, such as in the case of a counterparty’s insolvency. Furthermore, our ability to react to the cost of fuel, absent hedging, is limited because we set the price of tickets in advance of incurring fuel costs. Our ability to pass on any significant increases in aircraft fuel costs through fare increases could also be limited. In the event of a reduction in fuel prices compared to our hedged position, if any, our hedged positions could counteract the cost benefit of lower fuel prices and may require us to post cash margin collateral. In a falling fuel price environment, we may be required to make cash payments to our counterparties which may impair our liquidity position and increase our costs.

Please see “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Trends and Uncertainties Affecting Our Business—Aircraft Fuel.”

Restrictions on, or increased taxes applicable to, charges for ancillary products and services paid by airline passengers and burdensome consumer protection regulations or laws could harm our business, results of operations and financial condition.

During 2023, 2022 and 2021, we generated non-ticket revenues of $3,024.4 million, $2,612.6 million and $1,087.8 million, respectively. Our non-ticket revenues are generally generated from charges for, among other things, baggage, bookings through certain of our distribution channels, advance seat selection, itinerary changes and loyalty programs. The DOT has rules governing many facets of the airline-consumer relationship, including, for instance, price advertising, tarmac delays, bumping of passengers from flights, ticket refunds and the carriage of disabled passengers. If we are not able to remain in compliance with these rules, the DOT may subject us to fines or other enforcement action, including requirements to modify our passenger reservations system, which could have a material adverse effect on our business. The U.S. Congress and federal administrative agencies have investigated the increasingly common airline industry practice of unbundling the pricing of certain products and services. If new taxes are imposed on non-ticket revenues, or if other laws or regulations are adopted that make unbundling of airline products and services impermissible, or more cumbersome or expensive, our business, results of operations and financial condition could be harmed. Congressional and other government scrutiny may also change industry practice or public willingness to pay for ancillary services. See also “Risks Related to Our Business—We are subject to extensive and increasing regulation by the FAA, DOT, TSA and other U.S. and foreign governmental agencies, compliance with which could cause us to incur increased costs and adversely affect our business and financial results.”

The airline industry is particularly sensitive to changes in economic conditions. Adverse economic conditions would negatively impact our business, results of operations and financial condition.

Our business and the airline industry in general are affected by many changing economic conditions beyond our control, including, among others:

•changes and volatility in general economic conditions, including the severity and duration of any downturn in the U.S. or global economy and financial markets and the rate of inflation;

•changes in consumer preferences, perceptions, spending patterns or demographic trends, including any increased preference for higher-fare carriers offering higher amenity levels, and reduced preferences for low-fare carriers offering more basic transportation;

22

•higher levels of unemployment and varying levels of disposable or discretionary income in part due to the effect of high inflation rates and rising interest rates in the United States;

•depressed housing and stock market prices; and

•lower levels of actual or perceived consumer confidence.

These factors can adversely affect, and from time to time have adversely affected, our results of operations, our ability to obtain financing on acceptable terms and our liquidity. Unfavorable general economic conditions, such as higher unemployment rates, a constrained credit market, housing-related pressures and increased focus on reducing business operating costs, can reduce spending for price-sensitive leisure and business travel. For many travelers, in particular the price-sensitive travelers we serve, air transportation is a discretionary purchase that they may reduce or eliminate from their spending in difficult economic times. The overall decrease in demand for air transportation in the United States in 2008 and 2009 resulting from record high fuel prices and the economic recession required us to take significant steps to reduce our capacity, which reduced our revenues. Additionally, in 2020 and 2021, we were required to reduce our capacity as a result of a dramatic drop in demand due to, and restrictions imposed as a result of, the COVID-19 pandemic and demand has not fully recovered to pre-COVID-19 levels. Unfavorable economic conditions could also affect our ability to raise prices to counteract the effect of increased fuel, labor or other costs, resulting in a material adverse effect on our business, results of operations and financial condition.

The airline industry faces ongoing security concerns and related cost burdens, furthered by threatened or actual terrorist attacks or other hostilities, that could significantly harm our industry and our business.

The terrorist attacks of September 11, 2001 and their aftermath negatively affected the airline industry. The primary effects experienced by the airline industry included:

•substantial loss of revenue and flight disruption costs caused by the grounding of all commercial air traffic in or headed to the United States by the FAA for days after the terrorist attacks;

•increased security and insurance costs;

•increased concerns about future terrorist attacks;

•airport shutdowns and flight cancellations and delays due to security breaches and perceived safety threats; and

•significantly reduced passenger traffic and yields due to the subsequent dramatic drop in demand for air travel.

Since September 11, 2001, the Department of Homeland Security and the TSA have implemented numerous security measures that restrict airline operations and increase costs, and are likely to implement additional measures in the future. For example, following the widely publicized attempt of an alleged terrorist to detonate plastic explosives hidden underneath his clothes on a Northwest Airlines flight on Christmas Day in 2009, passengers became subject to enhanced random screening, which included pat-downs, explosive detection testing and body scans. Enhanced passenger screening, increased regulation governing carry-on baggage and other similar restrictions on passenger travel may further increase passenger inconvenience and reduce the demand for air travel. In addition, increased or enhanced security measures have tended to result in higher governmental fees imposed on airlines, resulting in higher operating costs for airlines, which we may not be able to pass on to consumers in the form of higher prices. Any future terrorist attacks or attempted attacks, even if not made directly on the airline industry, or the fear of such attacks or other hostilities (including elevated national threat warnings or selective cancellation or redirection of flights due to terror threats) would likely have a material adverse effect on our business, results of operations and financial condition and on the airline industry in general.

Airlines are often affected by factors beyond their control, any of which could harm our business, operating results and financial condition.

Like other airlines, our business is affected by factors beyond our control, including air traffic congestion at airports, air traffic control inefficiencies, major construction or improvements at airports at which we operate, adverse weather conditions, increased security measures, new travel-related taxes, the outbreak of disease, new regulations or policies from the presidential administration and Congress, and supply chain disruptions, in particular those causing inability to obtain, or delays in obtaining, aircraft or spare parts such as engines. Factors that cause flight delays frustrate passengers and increase costs, which in turn could adversely affect profitability. The federal government currently controls all U.S. airspace, and airlines are completely dependent on the FAA to operate that airspace in a safe, efficient and affordable manner. The air traffic control system, which is operated by the FAA, faces challenges in managing the growing demand for U.S. air travel. U.S. and foreign air-traffic controllers often rely on outdated technologies that routinely overwhelm the system and compel airlines to fly inefficient,

23

indirect routes resulting in delays. A significant portion of our operations is concentrated in markets such as South Florida, the Caribbean, Latin America and the Northeast and northern Midwest regions of the United States, which are particularly vulnerable to weather, airport traffic constraints and other delays. Adverse weather conditions and natural disasters, such as hurricanes affecting southern Florida and the Caribbean (such as Hurricanes Irma and Maria in September 2017, Hurricane Dorian in August 2019, Hurricane Laura in August 2020, Hurricane Ian in September 2022 and Hurricane Idalia in August

2023) as well as southern Texas (such as Hurricane Harvey in August 2017), winter snowstorms or earthquakes (such as the September 2017 earthquakes in Mexico City, Mexico and the December 2019 and January 2020 earthquakes in Puerto Rico) can cause flight cancellations, significant delays and facility disruptions. For example, during 2017, the timing and location of Hurricanes Irma and Maria produced a domino effect on our operations, resulting in approximately 1,400 flight cancellations and numerous flight delays, which resulted in an adverse effect on our results of operations. Cancellations or delays due to adverse weather conditions or natural disasters, air traffic control problems or inefficiencies, breaches in security, staffing shortages, or other factors may affect us to a greater degree than other, larger airlines that may be able to recover more quickly from these events, and therefore could harm our business, results of operations and financial condition to a greater degree than other air carriers. For example, during 2022, a number of adverse weather events, as well as increases in air traffic control programs and restrictions, led to a significant number of flight delays and cancellations. Because of our high utilization, point-to-point network, operational disruptions can have a disproportionate impact on our ability to recover. In addition, many airlines reaccommodate their disrupted passengers on other airlines at prearranged rates under flight interruption manifest agreements. We have been unsuccessful in procuring any of these agreements with our peers, which makes our recovery from disruption more challenging than for larger airlines that have these agreements in place. Similarly, outbreaks of pandemic or contagious diseases, such as Ebola, measles, avian flu, severe acute respiratory syndrome (SARS), H1N1 (swine) flu, Zika virus and COVID-19, could result in significant decreases in passenger traffic, the imposition of government restrictions in service, supply chain bottlenecks or issues, and staffing shortages and could have a material adverse impact on the airline industry. For example, in 2020 and 2021, the U.S. government and government authorities in other countries around the world implemented travel bans, testing requirements and other restrictions in response to the COVID-19 pandemic and recommended against air travel, which drastically reduced consumer demand for air travel. Any resurgence of COVID-19 or another pandemic or public health crisis that results in similar or other restrictions could have a material adverse effect on our business and results of operations. Air travel is continuing its resurgence following widespread adoption of vaccines, but the situation is fluid and actual capacity adjustments could be different than what we currently expect. Any increases in travel-related taxes could also result in decreases in passenger traffic. Any general reduction in airline passenger traffic could have a material adverse effect on our business, results of operations and financial condition. Moreover, U.S. federal government shutdowns may cause delays and cancellations or reductions in discretionary travel due to longer security lines, including as a result of furloughed government employees, or reductions in staffing levels, including air traffic controllers. U.S. government shutdowns may also impact our ability to take delivery of aircraft and commence operations in new domestic stations. Any extended shutdown like the one in January 2019 may have a negative impact on our operations and financial results. In addition, supply chain issues have led to delays in aircraft deliveries and negatively impacted our ability to source spare parts and complete maintenance on a timely basis, which could have an adverse effect on our business and results of operations.

Restrictions on or litigation regarding third-party membership discount programs could harm our business, operating results and financial condition.

We generate a relatively small but growing portion of our revenue from commissions, revenue share and other fees paid to us by third-party merchants for customer click-throughs, distribution of third-party promotional materials and referrals arising from products and services of the third-party merchants that we offer to our customers on our website. Some of these third-party referral-based offers are for memberships in discount programs or similar promotions made to customers who have purchased products from us, and for which we receive a payment from the third-party merchants for every customer that accepts the promotion. Certain of these third-party membership discount programs have been the subject of consumer complaints, litigation and regulatory actions alleging that the enrollment and billing practices involved in the programs violate various consumer protection laws or are otherwise deceptive. Any private or governmental claim or action that may be brought against us in the future relating to these third-party membership programs could result in our being obligated to pay damages or incurring legal fees in defending claims. These damages and fees could be disproportionate to the revenues we generate through these relationships. In addition, customer dissatisfaction or a significant reduction in or termination of the third-party membership discount offers on our website as a result of these claims could have a negative impact on our brand, and could have a material adverse effect on our business, results of operations and financial condition.

We face competition from air travel substitutes.

In addition to airline competition from traditional network airlines, other low-cost airlines and regional airlines, we also face competition from air travel substitutes. On our domestic routes, we face competition from some other transportation alternatives, such as bus, train or automobile. In addition, technology advancements may limit the demand for air travel. For example, video teleconferencing and other methods of electronic communication may reduce the need for in-person

24

communication and add a new dimension of competition to the industry as travelers seek lower-cost substitutes for air travel. If we are unable to adjust rapidly in the event the basis of competition in our markets changes, it could have a material adverse effect on our business, results of operations and financial condition.

Risks Related to Our Business

Increased labor costs, union disputes, employee strikes and other labor-related disruption may adversely affect our business, results of operations and financial conditions.

Our business is labor intensive, with labor costs representing approximately 27.6%, 22.1% and 32.4% of our total operating costs for 2023, 2022 and 2021, respectively. As of December 31, 2023, approximately 85% of our workforce was represented by labor unions. We cannot assure that our labor costs going forward will remain competitive, because in the future our labor agreements may be amended or become amendable and new agreements could have terms with higher labor costs; one or more of our competitors may significantly reduce their labor costs, thereby reducing or eliminating our comparative advantages as to one or more of such competitors; or our labor costs may increase in connection with our growth. As further described below, our aircraft maintenance technicians ("AMTs") voted to be represented by the Aircraft Mechanics Fraternal Association (the “AMFA”). We are currently negotiating a collective bargaining agreement. Any such negotiation may cause us to incur higher labor costs for our AMTs over the term of the agreement than we would have incurred absent such agreement. We may also become subject to additional collective bargaining agreements in the future given the possibility that other non-unionized workers may unionize.

Relations between air carriers and labor unions in the United States are governed by the RLA. Under the RLA, collective bargaining agreements generally contain “amendable dates” rather than expiration dates, subject to standard opener provisions, and the RLA requires that a carrier maintain the existing terms and conditions of employment following the amendable date through a multi-stage and usually lengthy series of bargaining processes overseen by the NMB. This process continues until either the parties have reached agreement on a new collective bargaining agreement or the parties have been released to “self-help” by the NMB. In most circumstances, the RLA prohibits strikes; however, after release by the NMB, carriers and unions are free to engage in self-help measures such as lockouts and strikes.

During 2017, we experienced operational disruption from pilot-related work action which adversely impacted our results. We obtained a temporary restraining order to enjoin further illegal labor action. In January 2018, under the guidance of the NMB-assigned mediators, the parties reached a tentative agreement. In February 2018, the pilot group voted to approve the current five-year agreement with us.

During the fourth quarter of 2022, we reached an agreement with ALPA for a new two-year agreement, which was ratified by ALPA members on January 10, 2023. The ratified agreement includes increased pay rates and other enhanced benefits.

In March 2016, under the supervision of the NMB, we reached a tentative agreement for a five-year contract with our flight attendants. Our flight attendants ratified the agreement in May 2016. In February 2021, we entered into a Letter of Agreement with the AFA-CWA to change the amendable date of the collective bargaining agreement from May 4, 2021 to September 1, 2021. All other terms of the collective bargaining agreement remained the same. In June 2021, the AFA-CWA notified us, as required by the RLA, that it intended to submit proposed changes to the collective bargaining agreement covering our flight attendants. We commenced negotiations with the AFA-CWA on September 27, 2021. In February 2023, we reached an agreement with our flight attendants which was ratified by the flight attendants on April 13, 2023 and becomes amendable in January 2026. The ratified agreement includes increased pay rates and other enhanced benefits.

Our dispatchers are represented by the PAFCA. In October 2018, we reached a tentative agreement with PAFCA for a new five-year agreement, which was ratified by the PAFCA members in October 2018. In May 2023, PAFCA provided notice that it intends to amend its Collective Bargaining Agreement with our dispatchers. The parties began negotiating changes to the CBA on July 12, 2023. As of December 31, 2023, we continued to negotiate with PAFCA.

Our ramp service agents are represented by IAMAW. Representation only applies to our Fort Lauderdale station where we have direct employees in the ramp service agent classification. In February 2020, the IAMAW notified us, as required by the RLA, that it intended to submit proposed changes to the collective bargaining agreement covering our ramp service agents which became amendable in June 2020. On September 28, 2021, we filed an “Application for Mediation Services” with the NMB. We were able to reach a tentative agreement with the IAMAW with the assistance of the NMB on October 16, 2021. Our ramp service agents ratified the five-year agreement in November 2021.

25

In June 2018, our passenger service agents voted to be represented by the TWU, but the representation only applies to our Fort Lauderdale station where we have direct employees in the passenger service classification. We began meeting with the TWU in late October 2018 to negotiate an initial collective bargaining agreement. During February 2022, we reached a tentative agreement with the TWU. Our passenger service agents ratified the five-year agreement on February 21, 2022.

In August 2022, our AMTs voted to be represented by AMFA as their collective bargaining agent. In November 2022, AMFA notified us of its intent to negotiate a CBA and began negotiations. In October 2023, AMFA filed for mediation with the NMB, and we are currently waiting for mediation dates from the NMB to continue negotiating with AMFA.

If we are unable to reach an agreement with any of our unionized work groups in current or future negotiations regarding the terms of their CBAs, we may be subject to work interruptions or stoppages, such as the strike by our pilots in June 2010 and the operational disruption from pilot-related work action experienced in 2017. A strike or other significant labor dispute with our unionized employees is likely to adversely affect our ability to conduct business. Any agreement we do reach could increase our labor and related expenses.

A deterioration in worldwide economic conditions may adversely affect our business, operating results, financial condition, liquidity and ability to obtain financing or access capital markets.

The general worldwide economy has in the past experienced downturns due to the effects of the COVID-19 pandemic, the European debt crisis, unfavorable U.S. economic conditions and slowing growth in certain Asian economies, including general credit market crises, collateral effects on the finance and banking industries, energy price volatility, concerns about inflation, higher interest rates, slower economic activity, decreased consumer confidence, reduced corporate profits and capital spending, adverse business conditions, geopolitical conflict, pandemic risks, government constraints on international trade and liquidity concerns. We cannot accurately predict the nature, extent, duration, effect or likelihood of any economic slowdown or the timing, strength or sustainability of a subsequent economic recovery worldwide or in the United States or the impact of the foregoing on the aviation industry.

Negative conditions in the general economy both in the United States and globally, including conditions resulting from changes in gross domestic product growth, declines in consumer confidence, labor shortages, inflationary pressures, rising interest rates, and financial and credit market fluctuations could result in decreases in spending on air travel and otherwise, increases in labor costs and delayed deliveries of aircraft, all of which could materially and adversely affect the growth of our business. In particular, although inflation in the United States has been relatively low in recent years, the U.S. economy has recently experienced a significant inflationary effect from, among other things, supply chain disruptions and governmental stimulus or fiscal policies adopted in response to the COVID-19 pandemic. While we cannot predict any future trends in the rate of inflation, there is currently significant uncertainty in the near-term economic outlook. Continued inflation would further raise our costs for labor, materials and services, which could negatively impact our profitability and cash flows. Additionally, we may be unable to raise our fares in amounts equal to the rate of inflation.

In addition, we have significant obligations for aircraft and spare engines that we have ordered from Airbus, IAE and Pratt & Whitney over the next several years, and we will need to finance these purchases. We may not have sufficient liquidity or creditworthiness to fund the purchase of aircraft and engines, including payment of pre-delivery deposit payments (“PDPs”), or for other working capital. Factors that affect our ability to raise financing or access the capital markets include market conditions in the airline industry, economic conditions, the perceived residual value of aircraft and related assets, the level and volatility of our earnings, our relative competitive position in the markets in which we operate, our ability to retain key personnel, our operating cash flows and legal and regulatory developments. Regardless of our creditworthiness, at times the market for aircraft purchase or lease financing has been very constrained due to such factors as the general state of the capital markets and the financial position of the major providers of commercial aircraft financing.

We rely on maintaining a high daily aircraft utilization rate to implement our low-cost structure, which makes us especially vulnerable to flight delays or cancellations or aircraft unavailability.

We maintain a high daily aircraft utilization rate. Our average daily aircraft utilization was 11.1 hours for 2023 and 10.7 hours for 2022. During 2021, we operated our aircraft at a slightly lower utilization level due to the COVID-19 pandemic leading to an average daily aircraft utilization of 9.7 hours, which was lower compared to prior years. Aircraft utilization is the average amount of time per day that our aircraft spend carrying passengers. Our revenue per aircraft can be increased by high daily aircraft utilization, which is achieved in part by reducing turnaround times at airports so we can fly more hours on average in a day. Aircraft utilization is reduced by delays and cancellations from various factors, many of which are beyond our control, including air traffic congestion at airports or other air traffic control problems, adverse weather conditions, increased security measures or breaches in security, international or domestic conflicts, terrorist activity, outbreaks of pandemics or contagious diseases or other changes in business conditions. A significant portion of our operations are concentrated in markets such as South Florida, the Caribbean, Latin America and the Northeast and northern Midwest regions of the United States, which are

26

particularly vulnerable to weather, airport traffic constraints and other delays. In addition, pulling aircraft out of service for unscheduled and scheduled maintenance, the occurrence of which will increase as our fleet ages, may materially reduce our average fleet utilization and require that we seek short-term substitute capacity at increased costs. Similarly, removing aircraft from service to inspect and repair the PW1100G engines could reduce our average fleet utilization. Due to the relatively small size of our fleet and high daily aircraft utilization rate, the unavailability of aircraft and resulting reduced capacity could have a material adverse effect on our business, results of operations and financial condition.

Our maintenance costs will increase as our fleet ages, and we will periodically incur substantial maintenance costs due to the maintenance schedules of our aircraft fleet.

As of December 31, 2023, the average age of our aircraft was approximately 6.6 years. Our relatively new aircraft require less maintenance now than they will in the future. Our fleet will require more maintenance as it ages and our maintenance and repair expenses for each of our aircraft will be incurred at approximately the same intervals. For our leased aircraft, we expect that the final heavy maintenance events will be amortized over the remaining lease term rather than until the next estimated heavy maintenance event, because we account for heavy maintenance under the deferral method. This will result in significantly higher depreciation and amortization expense related to heavy maintenance in the last few years of the leases as compared to the costs in earlier periods. Moreover, because our current fleet was acquired over a relatively short period, significant maintenance that is scheduled on each of these planes is occurring at roughly the same time, meaning we will incur our most expensive scheduled maintenance obligations, known as heavy maintenance, across our present fleet around the same time. These more significant maintenance activities result in out-of-service periods during which our aircraft are dedicated to maintenance activities and unavailable to fly revenue service. In addition, the terms of some of our lease agreements require us to pay maintenance reserves to the lessor in advance of the performance of major maintenance, resulting in our recording significant prepaid deposits on our consolidated balance sheet. Depending on their recoverability, these maintenance reserves may be expensed as supplemental rent. We expect scheduled and unscheduled aircraft maintenance expenses to increase over the next several years. Any significant increase in maintenance and repair expenses would have a material adverse effect on our business, results of operations and financial condition.

Our lack of marketing alliances could harm our business.

Many airlines, including the domestic traditional network airlines (American, Delta and United) have marketing alliances with other airlines, under which they market and advertise their status as marketing alliance partners. These alliances, such as OneWorld, SkyTeam and Star Alliance, generally provide for code-sharing, loyalty program reciprocity, coordinated scheduling of flights to permit convenient connections and other joint marketing activities. Such arrangements permit an airline to market flights operated by other alliance members as its own. This increases the destinations, connections and frequencies offered by the airline and provides an opportunity to increase traffic on that airline’s segment of flights connecting with alliance partners. We currently do not have any alliances with U.S. or foreign airlines. Our lack of marketing alliances puts us at a competitive disadvantage to traditional network carriers who are able to attract passengers through more widespread alliances, particularly on international routes, and that disadvantage may result in a material adverse effect on our passenger traffic, business, results of operations and financial condition.

We are subject to extensive and increasing regulation by the FAA, DOT, TSA and other U.S. and foreign governmental agencies, compliance with which could cause us to incur increased costs and adversely affect our business and financial results.

Airlines are subject to extensive and increasing regulatory and legal compliance requirements, both domestically and internationally, that involve significant costs. In the last several years, Congress has passed laws, and the DOT, FAA and TSA have issued regulations, relating to the operation of airlines that have required significant expenditures. We expect to continue to incur expenses in connection with complying with government regulations. Additional laws, regulations, taxes and increased airport rates and charges have been proposed from time to time that could significantly increase the cost of airline operations or reduce the demand for air travel. If adopted, these measures could have the effect of raising ticket prices, reducing revenue and increasing costs.

The DOT has been aggressive in enforcing regulations for violations of the tarmac delay rules, passenger with disability rules, advertising rules and other consumer protection rules that could increase the cost of airline operations or reduce revenues. In December 2020, the DOT issued a Final Rule on Traveling by Air with Service Animals. This rule limits service animals to a dog that is individually trained to do work or perform tasks for the benefit of a person with a disability, and no longer considers an emotional support animal to be a service animal. This eliminates the requirement to carry emotional support animals for free, and will likely reduce costs. Additionally, in December 2020, the DOT withdrew a Request for Information soliciting information on whether airline restrictions on the distribution or display of airline flight information constitute an

27

unfair and deceptive business practice and/or an unfair method of competition. The DOT said that decisions on how and where to sell their services should be left to the airlines.

In its first day in office, the Biden Administration issued an executive order that froze review and approval of any new rulemaking. This freeze led the DOT to withdraw the Final Rule on Tarmac Delay and the Advance Notice of Proposed Rulemaking (ANPRM) on Airfare Advertising. The ANPRM may not be reissued.

In October 2018, Congress passed the FAA Reauthorization Act of 2018, which extends FAA funds through fiscal year 2023. The legislation contains provisions which could have effects on our results of operations and financial condition. Among other provisions, the new law requires the DOT to lift the payment cap on denied boarding compensation, create new requirements for the treatment of disabled passengers, and treble the maximum civil penalty for damage to wheelchairs and other assistive devices or for injuring a disabled passenger. Under the Act, the FAA is required to issue rules establishing minimum dimensions for passenger seats, including seat pitch, width and length. The Act also establishes new rest requirements for flight attendants and requires, within one year, that the FAA issue an order mandating installation of a secondary cockpit barrier on each new aircraft.

In December 2023, Congress passed the Airport and Airway Extension Act of 2023, Part II, which extends FAA funds through March 8, 2024 while Congress works to pass a long-term extension. A five-year extension of FAA funds has passed the House of Representatives, but remains stalled in the Senate. In the event that authorization of FAA funds lapses, our operations and results of operations could be materially adversely affected.

In January 2021, the DOT issued a final rule, effective April 2021, to clarify that the maximum amount of Denied Boarding Compensation (DBC) that a carrier may provide to a passenger denied boarding involuntarily is not limited. We cannot forecast how eliminating this maximum amount of payment will affect our costs.

In 2021 and 2022, the DOT issued several NPRMs relating to air travel and airline ticketing and fees. In July 2021, the DOT issued a NRPM requiring airlines to refund checked bag fees for delayed bags if they are not delivered to the passenger within a specified number of hours and refunding ancillary fees for services related to air travel that passengers did not receive. In November 2021, the DOT reopened the comment period on a NPRM regarding short-term improvements to lavatory accessibility, including new proposed requirements for OBWs (Part 1). This NPRM was to gather information about all aspects of OBW design, including stowage, before issuing any final binding regulation on the topic. In March 2022, the DOT issued a NPRM (Part 2) requiring airlines to ensure that at least one lavatory on new single-aisle aircraft with at least 125 passenger seats is large enough to permit a passenger with a disability (with the help of an assistant, if necessary) to approach, enter and maneuver within the lavatory, as necessary, to use all lavatory facilities and to leave by means of the aircraft’s on-board wheel chair. If enacted as currently proposed, this NPRM (Part 2) would apply to new aircraft ordered 18 years or delivered 20 years after the effective date of a final rule. In August 2022, the DOT issued a NPRM requiring airlines and ticket agents to provide non-expiring travel vouchers or credits to consumers holding non-refundable tickets for scheduled flights to, from or within the United States as a result of the carrier cancelling or making a significant change to a scheduled flight, a serious communicable disease or for several other reasons. The NPRM will further define the terms “significant change” and “cancellation” and will require airlines and ticket agents to provide refunds if they receive significant financial assistance from the government as a result of a public health emergency. As of December 31, 2023, a final rule has not been issued; however, it is our understanding that the DOT will combine this NPRM with the July 2021 NPRM, regarding the refunding of certain checked bag fees ancillary fees. In October 2022, the DOT issued a NRPM which would require airlines to increase disclosure of bag fees, change and cancellation fees, and family seating policies during the ticket purchase process in an effort to improve the transparency of airline pricing. The comment period closed on January 23, 2023. If any of these NPRMs are enacted as proposed, they may increase our costs and our results of operations could be materially adversely affected.

We cannot assure that these and other laws or regulations enacted in the future will not harm our business. In addition, the TSA mandates the federalization of certain airport security procedures and imposes additional security requirements on airports and airlines, most of which are funded by a per ticket tax on passengers and a tax on airlines. We cannot forecast what additional security and safety requirements may be imposed in the future or the costs or revenue impact that would be associated with complying with such requirements.

Our ability to operate as an airline is dependent on our maintaining certifications issued to us by the DOT and the FAA. The FAA has the authority to issue mandatory orders relating to, among other things, the grounding of aircraft, inspection of aircraft, installation of new safety-related items and removal and replacement of aircraft parts that have failed or may fail in the future. A decision by the FAA to ground, or require time consuming inspections of or maintenance on, our aircraft, for any reason, could negatively affect our business and financial results. Federal law requires that air carriers operating large aircraft

28

be continuously “fit, willing and able” to provide the services for which they are licensed. Our “fitness” is monitored by the DOT, which considers factors such as unfair or deceptive competition, advertising, baggage liability and disabled passenger transportation. While the DOT has seldom revoked a carrier's certification for lack of fitness, such an occurrence would render it impossible for us to continue operating as an airline. The DOT may also institute investigations or administrative proceedings against airlines for violations of regulations.

The U.S. government is under persistent pressure to implement cost cutting and efficiency initiatives. In addition, the U.S. government has recently and may in the future experience delays in the completion of its budget process which could delay funding for government departments and agencies that regulate or otherwise are tied to the aviation industry, including the DOT and FAA. To the extent that any such initiatives or budgeting delays affect the operations of these government departments and agencies, including by forcing mandatory furloughs of government employees, our operations and results of operations could be materially adversely affected.

International routes are regulated by treaties and related agreements between the United States and foreign governments. Our ability to operate international routes is subject to change because the applicable arrangements between the United States and foreign governments may be amended from time to time. Our access to new international markets may be limited by our ability to obtain the necessary certificates to fly the international routes. In addition, our operations in foreign countries are subject to regulation by foreign governments and our business may be affected by changes in law and future actions taken by such governments, including granting or withdrawal of government approvals and restrictions on competitive practices. We are subject to numerous foreign regulations based on the large number of countries outside the United States where we currently provide service. If we are not able to comply with this complex regulatory regime, our business could be significantly harmed. Please see “Business — Government Regulation.”

Government-imposed travel requirements and entry bans from certain countries based on emerging viruses or variants of existing viruses could be imposed in the future. We will continue to comply with all contagious disease requirements issued by the U.S. and foreign governments, but we cannot forecast what additional requirements may be imposed in the future or the extent of any pre-travel testing requirements that may be under consideration in the United States and that may be in place, or renewed, in any foreign jurisdiction we serve, including the effect of such requirements on passenger demand or the costs or revenue impact that would be associated with complying with such requirements.

Changes in legislation, regulation and government policy have affected, and may in the future have a material adverse effect on, our business.

Changes in, and uncertainty with respect to, legislation, regulation and government policy at the local, state or federal level have affected, and may in the future significantly impact, our business and the airline industry. For example, the Tax Cuts and Jobs Act, enacted on December 22, 2017, limits deductions for borrowers for net interest expense on debt. Specific legislative and regulatory proposals that could have a material impact on us in the future include, but are not limited to, infrastructure renewal programs; changes to immigration policy; modifications to international trade policy, including withdrawing from trade agreements and imposing tariffs; changes to financial legislation, including the partial or full repeal of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”) or the Tax Cuts and Jobs Act; public company reporting requirements; environmental regulation and antitrust enforcement. Any such changes may make it more difficult and/or more expensive for us to obtain new aircraft or engines and parts to maintain existing aircraft or engines or make it less profitable or prevent us from flying to or from some of the destinations we currently serve.

To the extent that any such changes have a negative impact on us or the airline industry, including as a result of related uncertainty, these changes may materially and adversely impact our business, financial condition, results of operations and cash flows.

Any tariffs imposed on commercial aircraft and related parts imported from outside the United States may have a material adverse effect on our fleet, business, financial condition and our results of operations.

Certain of the products and services that we purchase, including our aircraft and related parts, are sourced from suppliers located in foreign countries, and the imposition of new tariffs, or any increase in existing tariffs, by the U.S. government on the importation of such products or services could materially increase the amounts we pay for them. In early October 2019, the World Trade Organization ruled that the United States could impose $7.5 billion in retaliatory tariffs in response to illegal European Union subsidies to Airbus. On October 18, 2019, the United States imposed these tariffs on certain imports from the European Union, including a 10% tariff on new commercial aircraft. In February 2020, the United States announced an increase to this tariff from 10% to 15%. These tariffs apply to aircraft that we are already contractually obligated to purchase. In June 2021, the United States Trade Representative announced that the United States and European Union had agreed to suspend

29

reciprocal tariffs on large civilian aircraft for five years, pending discussions to resolve their trade dispute. However, these tariffs are under continuing review and at any time could be increased, decreased, eliminated or applied to a broader range of products we use. The imposition of these tariffs may substantially increase the cost of, among other things, imported new Airbus aircraft and parts required to service our Airbus fleet, which in turn could have a material adverse effect on our business, financial condition and/or results of operations. We may also seek to postpone or cancel delivery of certain aircraft currently scheduled for delivery, and we may choose not to purchase as many aircraft as we intended in the future. Any such action could have a material adverse effect on the size of our fleet, business, financial condition and/or results of operations.

We may not be able to implement our growth strategy.

Our growth strategy includes acquiring additional aircraft, increasing the frequency of flights and size of aircraft used in markets we currently serve, and expanding the number of markets we serve where our low-cost structure would likely be successful. Effectively implementing our growth strategy is critical for our business to achieve economies of scale and to sustain or increase our profitability. We face numerous challenges in implementing our growth strategy, including our ability to:

•maintain profitability;

•acquire delivery positions of and/or financing for new or used aircraft;

•access airports located in our targeted geographic markets where we can operate routes in a manner that is consistent with our cost strategy;

•acquire new and used aircraft in accordance with our intended delivery schedule, and obtain sufficient spare parts or related support services from our suppliers on a timely basis;

•gain access to international routes;

•access sufficient gates and other services at airports we currently serve or may seek to serve; and

•maintain efficient utilization and capacity of our existing aircraft.

Our growth is dependent upon our ability to maintain a safe and secure operation and requires additional personnel, equipment and facilities. An inability to hire and retain personnel, timely secure the required equipment and facilities in a cost-effective manner, efficiently operate our expanded facilities or obtain the necessary regulatory approvals may adversely affect our ability to achieve our growth strategy, which could harm our business. In addition, expansion to new markets may have other risks due to factors specific to those markets. We may be unable to foresee all of the existing risks upon entering certain new markets or respond adequately to these risks, and our growth strategy and our business may suffer as a result. In addition, our competitors may reduce their fares and/or offer special promotions to deter our entry into a new market or to stop our growth into existing markets or new markets. We cannot assure you that we will be able to profitably expand our existing markets or establish new markets.

Some of our target growth markets in the Caribbean and Latin America include countries with less developed economies that may be vulnerable to unstable economic and political conditions, such as significant fluctuations in gross domestic product, interest and currency exchange rates, high inflation, civil disturbances, government instability, nationalization and expropriation of private assets and the imposition of taxes or other charges by governments. The occurrence of any of these events in markets served by us and the resulting instability may adversely affect our ability to implement our growth strategy.

In 2008, in response to record high fuel prices and rapidly deteriorating economic conditions, we modified our growth plans by terminating our leases for seven aircraft. We incurred significant expenses relating to our lease terminations, and have incurred additional expenses to acquire new aircraft in place of those under the terminated leases as we expanded our network. In November 2023, we announced that we will discontinue service at Denver International Airport, effective January 9, 2024, as a result of underperforming routes and Pratt & Whitney’s GTF engine availability issues. See “—We depend on a limited

number of suppliers for our aircraft and engines.” We may in the future determine to reduce further our future growth plans from previously announced levels, which may impact our business strategy and future profitability.

We rely heavily on technology and automated systems to operate our business and any failure of these technologies or systems or failure by their operators could harm our business.

We are highly dependent on technology and automated systems to operate our business and achieve low operating costs. These technologies and systems include our computerized airline reservation system, flight operations system, financial planning, management and accounting system, telecommunications systems, website, maintenance systems and check-in

30

kiosks. The performance and reliability of our technology are critical to our ability to operate and compete effectively. The execution of our strategic plans could be negatively affected by (i) our ability to timely and effectively implement, transition, and maintain related information technology systems and infrastructure; (ii) our ability to effectively balance our investment of incremental operating expenses and capital expenditures related to our strategies against the need to effectively control cost; and (iii) our dependence on third parties with respect to our ability to implement our strategic plans. We cannot assure you that our security measures, change control procedures and disaster recovery plans will be adequate to prevent disruptions or delays. Disruption in or changes to these systems could result in an interruption to our operations or loss of important data. Any of the foregoing could result in a material adverse effect on our business, reputation, results of operations and financial condition.

In order for our operations to work efficiently, our website and reservation system must be able to accommodate a high volume of traffic, maintain secure information and deliver flight information with a high degree of reliability. Substantially all of our tickets are issued to passengers as electronic tickets. We depend on our reservation system, which is hosted and maintained under a long-term contract by a third-party service provider, to be able to issue, track and accept these electronic tickets. If our third-party service provider experiences operational failures or claims that it cannot perform as a result of a force majeure, due to the effects of COVID-19 or otherwise, we may not be able to operate our reservation system. If our reservation system fails or experiences interruptions, and we are unable to book seats for any period of time, we could lose a significant amount of revenue as customers book seats on competing airlines. We have experienced short duration reservation system outages from time to time and may experience similar outages in the future. For example, in November 2010, we experienced a significant service outage with our third-party reservation service provider on the day before Thanksgiving, one of the industry’s busiest travel days and in August 2013, we experienced a 13-hour outage that affected our sales and customer service response times. We also rely on third-party service providers of our other automated systems for technical support, system maintenance and software upgrades. If our automated systems are not functioning or if the current providers were to fail to adequately provide technical support or timely software upgrades for any one of our key existing systems, we could experience service disruptions, which could harm our business and result in the loss of important data, increase our expenses and decrease our revenues. In the event that one or more of our primary technology or systems’ vendors goes into bankruptcy, ceases operations or fails to perform as promised, replacement services may not be readily available on a timely basis, at competitive rates or at all and any transition time to a new system may be significant.

In addition, our automated systems cannot be completely protected against events that are beyond our control, including natural disasters, cyber attacks, disruption of electrical grid or telecommunications failures. Substantial or sustained system failures could cause service delays or failures and result in our customers purchasing tickets from other airlines. We have implemented security measures and change control procedures and have disaster recovery plans; however, we cannot assure you that these measures are adequate to prevent disruptions. Disruption in, changes to or a breach of, these systems could result in a disruption to our business and the loss of important data. Moreover, in the event of system outages or interruptions, we may not be able to recover from our information technology and software providers all or any portion of the costs or business losses we may incur. Any of the foregoing could result in a material adverse effect on our business, results of operations and financial condition.

We are subject to cyber security risks and may incur increasing costs in an effort to minimize those risks.

Our business employs systems and websites that allow for the secure storage and transmission of proprietary or confidential information regarding our customers, employees, suppliers and others, including personal identification information, credit card data and other confidential information. Security breaches could expose us to a risk of loss or misuse of this information, litigation and potential liability. Although we take steps to secure our management information systems, and although auditors review and approve the security configurations and management processes of these systems, including our computer systems, intranet and internet sites, email and other telecommunications and data networks, the security measures we have implemented may not be effective, and our systems may be vulnerable to theft, loss, damage and interruption from a number of potential sources and events, including unauthorized access or security breaches, natural or man-made disasters, cyber attacks (including ransom attacks in which malicious persons encrypt our systems, steal data, or both, and demand payment for decryption of systems or to avoid public release of data), computer viruses, power loss or other disruptive events. We may not have the resources or technical sophistication to anticipate or prevent rapidly evolving types of cyber attacks. Attacks may be targeted at us, our customers and suppliers, or others who have entrusted us with information. In addition, attacks not targeted at us, but targeted solely at suppliers, may cause disruption to our computer systems or a breach of the data that we maintain on customers, employees, suppliers and others.

Actual or anticipated attacks may cause us (and at times have caused us) to incur increasing costs, including costs to deploy additional personnel and protection technologies, train employees and engage third-party experts and consultants, or costs incurred in connection with the notifications to employees, suppliers or the general public as part of our notification obligations to the various governments that govern our business. Advances in computer capabilities, new technological

31

discoveries, or other developments may result in the breach or compromise of technology used by us to protect transaction or other data. In addition, data and security breaches can also occur as a result of non-technical issues, including breaches by us or by persons with whom we have commercial relationships that result in the unauthorized release of personal or confidential information. Our reputation, brand and financial condition could be adversely affected if, as a result of a significant cyber event or other security issues: our operations are disrupted or shut down; our confidential, proprietary information is stolen or disclosed; we incur costs or are required to pay fines in connection with stolen customer, employee or other confidential information; we must dedicate significant resources to system repairs or increase cyber security protection; or we otherwise incur significant litigation or other costs.

Our processing, storage, use and disclosure of personal data could give rise to liabilities as a result of governmental regulation.

In the processing of our customer transactions, we receive, process, transmit and store a large volume of identifiable personal data, including financial data such as credit card information. This data is increasingly subject to legislation and regulation, such as the California Consumer Privacy Act and the Fair Accurate Credit Transparency Act and Payment Card Industry legislation, typically intended to protect the privacy of personal data that is collected, processed and transmitted. More generally, we rely on consumer confidence in the security of our system, including our website on which we sell the majority of our tickets. Our business, results of operations and financial condition could be adversely affected if we are unable to comply with existing privacy obligations or legislation or regulations are expanded to require changes in our business practices.

We may not be able to maintain or grow our non-ticket revenues.

Our business strategy includes expanding our portfolio of ancillary products and services. There can be no assurance that passengers will pay for additional ancillary products and services or that passengers will continue to choose to pay for the ancillary products and services we currently offer. Further, regulatory initiatives could adversely affect ancillary revenue opportunities. Failure to maintain our non-ticket revenues would have a material adverse effect on our results of operations and financial condition. Please see “Risks Related to Our Industry—Restrictions on, or increased taxes applicable to, charges for ancillary products and services paid by airline passengers and burdensome consumer protection regulations or laws could harm our business, results of operations and financial condition.”

Our inability to expand or operate reliably or efficiently out of our key airports where we maintain a large presence could have a material adverse effect on our business, results of operations and financial condition.

We are highly dependent on markets served from airports where we maintain a large presence. Our results of operations may be affected by actions taken by governmental or other agencies or authorities having jurisdiction over our operations at airports, including, but not limited to:

•increases in airport rates and charges;

•limitations on take-off and landing slots, airport gate capacity or other use of airport facilities;

•termination of our airport use agreements, some of which can be terminated by airport authorities with little notice to us;

•increases in airport capacity that could facilitate increased competition;

•international travel regulations such as customs and immigration;

•increases in taxes;

•changes in the law that affect the services that can be offered by airlines in particular markets and at particular airports;

•restrictions on competitive practices;

•the adoption of statutes or regulations that impact customer service standards, including security standards; and

•the adoption of more restrictive locally-imposed noise regulations or curfews.

In general, any changes or disruptions in airport operations could have a material adverse effect on our business, results of operations and financial condition.

We rely on third-party service providers to perform functions integral to our operations.

32

We have entered into agreements with third-party service providers to furnish certain facilities and services required for our operations, including ground handling, catering, passenger handling, engineering, maintenance, refueling, reservations and airport facilities as well as administrative and support services. We are likely to enter into similar service agreements in new markets we decide to enter, and there can be no assurance that we will be able to obtain the necessary services at acceptable rates.

Although we seek to monitor the performance of third parties that provide us with our reservation system, ground handling, catering, passenger handling, engineering, maintenance services, refueling and airport facilities, the efficiency, timeliness and quality of contract performance by third-party service providers are often beyond our control, and any failure by our service providers to perform their contracts, including as a result of operational failures or a force majeure, due to the effects of COVID-19 or otherwise, may have an adverse impact on our business and operations. For example, in 2008, our call center provider went bankrupt. Though we were able to quickly switch to an alternative vendor, we experienced a significant business disruption during the transition period and a similar disruption could occur in the future if we changed call center providers or if an existing provider ceased to be able to serve us. We expect to be dependent on such third-party arrangements for the foreseeable future.

We rely on third-party distribution channels to distribute a portion of our airline tickets.

We rely on third-party distribution channels, including those provided by or through global distribution systems, or GDSs, conventional travel agents and online travel agents, or OTAs, to distribute a portion of our airline tickets, and we expect in the future to rely on these channels to an increasing extent to collect ancillary revenues. These distribution channels are more expensive and at present have less functionality in respect of ancillary revenues than those we operate ourselves, such as our call centers and our website. Certain of these distribution channels also effectively restrict the manner in which we distribute our products generally. To remain competitive, we will need to successfully manage our distribution costs and rights, and improve the functionality of third-party distribution channels, while maintaining an industry-competitive cost structure. Negotiations with key GDSs and OTAs designed to manage our costs, increase our distribution flexibility, and improve functionality could be contentious, could result in diminished or less favorable distribution of our tickets, and may not provide the functionality we require to maximize ancillary revenues. Any inability to manage our third-party distribution costs, rights and functionality at a competitive level or any material diminishment in the distribution of our tickets could have a material adverse effect on our competitive position and our results of operations. Moreover, our ability to compete in the markets we serve may be threatened by changes in technology or other factors that may make our existing third-party sales channels impractical, uncompetitive or obsolete.

Our reputation and business could be materially adversely affected in the event of an emergency, accident or similar incident involving our aircraft.

We are exposed to potential significant losses in the event that any of our aircraft is subject to an emergency, accident, terrorist incident or other similar incident, and significant costs related to passenger claims, repairs or replacement of a damaged aircraft and its temporary or permanent loss from service. There can be no assurance that we will not be affected by such events or that the amount of our insurance coverage will be adequate in the event such circumstances arise and any such event could cause a substantial increase in our insurance premiums. Please see “Risks Related to Our Business—Increases in insurance costs or significant reductions in coverage could have a material adverse effect on our business, financial condition and results of operations.” In addition, any future aircraft emergency, accident or similar incident, even if fully covered by insurance or even if it does not involve our airline, may create a public perception that our airline or the equipment we fly is less safe or reliable than other transportation alternatives, or could cause us to perform time consuming and costly inspections on our aircraft or engines which could have a material adverse effect on our business, results of operations and financial condition.

Negative publicity regarding our customer service or otherwise could have a material adverse effect on our business.

In the past, we have experienced a relatively high number of customer complaints related to, among other things, our customer service and reservations and ticketing systems. In particular, we generally experience a higher volume of complaints when we make changes to our unbundling policies, such as charging for baggage. In addition, in 2009, we entered into a consent order with the DOT for our procedures for bumping passengers from oversold flights and our handling of lost or damaged baggage. Under the consent order, we were assessed a civil penalty of $375,000, of which we were required to pay $215,000 based on an agreement with the DOT and not having similar violations in the year after the date of the consent order. Further, media reports about incidents on our aircraft unrelated to customer complaints could negatively impact our reputation and our operations. If we do not meet our customers’ expectations with respect to reliability and service, customers could decide not to fly with us, which would materially adversely affect our business and reputation.

We depend on a limited number of suppliers for our aircraft and engines.

33

One of the elements of our business strategy is to save costs by operating a single-family aircraft fleet - currently Airbus A320-family, single-aisle aircraft, powered by engines manufactured by IAE and Pratt & Whitney. If any of Airbus, IAE or Pratt & Whitney become unable to perform its contractual obligations, or if we are unable to acquire or lease aircraft or engines from these or other owners, operators or lessors on acceptable terms, we would have to find other suppliers for a similar type of aircraft or engine. In late 2022, we were notified by Airbus that a number of the aircraft we originally had scheduled for delivery in 2023 will be delayed into 2024 and beyond. These delays have required us to reduce capacity expectations for the next year or so. If we have to lease or purchase aircraft from another supplier, we would lose the significant benefits we derive from our current single fleet composition. We may also incur substantial transition costs, including costs associated with retraining our employees, replacing our manuals and adapting our facilities and maintenance programs. Our operations could also be harmed by the failure or inability of aircraft, engine and parts suppliers to provide sufficient spare parts or related support services on a timely basis, particularly in connection with new-generation introductory technology. Our business would be significantly harmed if a design defect or mechanical problem with any of the types of aircraft, engines or components currently on order or that we operate were discovered that would halt or delay our aircraft delivery stream or that would ground any of our aircraft while the defect or problem was corrected, assuming it could be corrected at all. Since the addition of A320neo aircraft in 2016, we had experienced introductory issues with the new-generation PW1100G engines, designed and manufactured by Pratt & Whitney, which had previously resulted in diminished service availability of such aircraft. Beginning in the second half of 2020, the A320neo aircraft fleet reliability had stabilized and the PW1100G engine technical issues had improved. However, beginning in the second half of 2022, we began experiencing reliability issues with the PW1100G engines once again resulting in diminished service availability of aircraft. Supply chain delivery issues and limited capacity at engine maintenance, repair, and overhaul (“MRO”) shops available to service PW1100G engines have resulted in extended turnaround time to perform these inspections and the modifications required to improve the reliability of these engines. These impacts are expected to continue throughout 2024 and beyond, until supply chain and engine MRO shop capacity returns to required levels to support our growth. In addition, in July 2023, Pratt & Whitney announced that it had determined that a rare condition in the powdered metal used to manufacture certain engine parts will require accelerated inspection of the GTF fleet, which powers the A320neo aircraft. As of December 31, 2023, we have removed five engines from service, three of which are currently awaiting induction for inspection. Pratt & Whitney notified us that all GTF engines in its fleet, including the engines slotted for future aircraft deliveries, for a yet to be determined period, may be subject to the removal and inspection, or replacement, of the powdered metal high-pressure turbine and compressor discs. We currently estimate these engines will require removal and inspection in 2024, but continuing through 2026. For 2024, we estimate the average number of grounded neo aircraft will climb steadily from 13 in January 2024 to 41 in December 2024, averaging 26 grounded for the full year 2024. Lower capacity resulting from manufacturer or supplier issues may lead to significant impact on our business and operating results. For instance, partially as a result of the Pratt & Whitney engine issues, in November 2023, we announced that we will discontinue service at Denver International Airport, effective January 9, 2024.

We cannot be certain that new technical issues may be mitigated given the relatively short life these engines have been in service. We continuously work with the engine manufacturer to secure support and relief in connection with possible engine related operation disruptions. Should appropriate design or mechanical modifications not be implemented or not be effective, this could materially adversely affect our business, results of operations and financial condition. These types of events, if appropriate design or mechanical modifications cannot be implemented, and related operations disruptions, including from required inspections, could materially adversely affect our business, results of operations and financial condition. Moreover, the use of our aircraft could be suspended or restricted by regulatory authorities in the event of actual or perceived mechanical or design problems. Our business would also be significantly harmed if the public began to avoid flying with us due to an adverse perception of the types of aircraft, engines or components that we operate stemming from safety concerns or other problems, whether real or perceived, or in the event of an accident involving those types of aircraft, engines or components. Carriers that operate a more diversified fleet are better positioned than we are to manage such events.

Reduction in demand for air transportation, or governmental reduction or limitation of operating capacity, in the domestic U.S., Caribbean or Latin American markets could harm our business, results of operations and financial condition.

A significant portion of our operations are conducted to and from the domestic U.S., Caribbean or Latin American markets. Our business, results of operations and financial condition could be harmed if we lost our authority to fly to these markets, by any circumstances causing a reduction in demand for air transportation, or by governmental reduction or limitation of operating capacity, in these markets, such as adverse changes in local economic or political conditions, negative public perception of these destinations, unfavorable weather conditions, public health concerns or terrorist-related activities. Furthermore, our business could be harmed if jurisdictions that currently limit competition allow additional airlines to compete on routes we serve. Many of the countries we serve are experiencing either economic slowdowns or recessions, which may translate into a weakening of demand and could harm our business, results of operations and financial condition.

34

Increases in insurance costs or significant reductions in coverage could have a material adverse effect on our business, financial condition and results of operations.

We carry insurance for third-party liability, passenger liability, property damage and all-risk coverage for damage to our aircraft. As a result of the September 11, 2001 terrorist attacks, aviation insurers significantly reduced the amount of insurance coverage available to commercial air carriers for liability to persons other than employees or passengers for claims resulting from acts of terrorism, war or similar events (war risk insurance). Accordingly, our insurance costs increased significantly and our ability to continue to obtain certain types of insurance remains uncertain. While the price of commercial insurance has declined since the period immediately after the terrorist attacks, in the event commercial insurance carriers further reduce the amount of insurance coverage available to us, or significantly increase its cost, we would be adversely affected. We currently maintain commercial airline insurance with several underwriters. However, there can be no assurance that the amount of such coverage will not be changed, or that we will not bear substantial losses from accidents. We could incur substantial claims resulting from an accident in excess of related insurance coverage that could have a material adverse effect on our results of operations and financial condition. Renewing coverage may result in higher premiums and more restrictive terms. Our business, results of operations and financial condition could be materially adversely affected if we are unable to obtain adequate insurance.

Failure to comply with applicable environmental regulations could have a material adverse effect on our business, results of operations and financial condition.

We are subject to increasingly stringent federal, state, local and foreign laws, regulations and ordinances relating to the protection of the environment, including those relating to emissions to the air, discharges to surface and subsurface waters, safe drinking water and the management of hazardous substances, oils and waste materials. Compliance with all environmental laws and regulations can require significant expenditures and any future regulatory developments in the United States and abroad could adversely affect operations and increase operating costs in the airline industry. For example, climate change legislation was previously introduced in Congress and such legislation could be re-introduced in the future by Congress and state legislatures, and could contain provisions affecting the aviation industry, compliance with which could result in the creation of substantial additional costs to us. Similarly, the EPA issued a rule that regulates larger emitters of greenhouse gases. Future operations and financial results may vary as a result of such regulations. Compliance with these regulations and new or existing regulations that may be applicable to us in the future could increase our cost base and could have a material adverse effect on our business, results of operations and financial condition.

There is also an increasing international focus on climate change, carbon emissions and environmental regulation. The principal deputy assistant secretary for aviation and international affairs at the DOT spent the last 25 years working on international aviation climate change policy at Environmental Defense Fund. This may signal increased emphasis on new environmental regulation on commercial aviation.

Members of the International Civil Aviation Organization (“ICAO”) have been negotiating a global agreement in greenhouse gas emissions for the aviation industry. In October 2016, the ICAO adopted the Carbon Offsetting and Reduction Scheme for International Aviation (“CORSIA”), which is a global, market-based emissions offset program designed to encourage carbon-neutral growth beyond 2020. Further, in June 2018 the ICAO adopted standards pertaining to the collection and sharing of information in international aviation emissions beginning in 2019. We are a participant in the CORSIA program. The CORSIA will increase operating costs for Spirit and other U.S. airlines that operate internationally. The CORSIA is being implemented in phases beginning with a voluntary pilot which began in 2021 and will continue through 2023. The COVID-19 pandemic has depressed international aviation such that 2020 emissions will not be included in setting a baseline. Airlines will have until January 2025 to cancel eligible emissions units to comply with their total offsetting requirements for the pilot phase. From 2021, all flights will be subject to offsetting with certain exceptions. Certain details are still being developed and the impact cannot be fully predicted. Compliance with CORSIA could significantly increase our operating costs. The potential impact of CORSIA or other emissions-related requirements on our costs will ultimately depend on a number of factors, including baseline emissions, the price of emission allowances or offsets that we would need to acquire, the efficiency of our fleet and the number of flights subject to these requirements. These costs have not been completely defined and could fluctuate.

Governmental authorities in several U.S. and foreign cities are also considering or have already implemented aircraft noise reduction programs, including the imposition of nighttime curfews and limitations on daytime take-offs and landings. We have been able to accommodate local noise restrictions imposed to date, but our operations could be adversely affected if locally-imposed regulations become more restrictive or widespread.

If we are unable to attract and retain qualified personnel or fail to maintain our company culture, our business, results of operations and financial condition could be harmed.

Our business is labor intensive. We require large numbers of pilots, flight attendants, maintenance technicians and other personnel. The airline industry has from time to time experienced a shortage of qualified personnel, particularly with respect to pilots and maintenance technicians. In addition, we currently face, and may continue to face, high employee turnover, including with respect to our pilots. We may be required to increase wages and/or benefits in order to attract and retain qualified personnel. If we are unable to hire, train and retain qualified employees, our operations and business could be harmed and we may be unable to implement our growth plans. Since 2021, we have experienced a shortage of qualified workers as the U.S. labor market tightened, in particular shortages of qualified pilots. As a result, our operations were negatively impacted and our labor costs have increased substantially in 2021 and through 2023.

In addition, as we hire more people and grow, we believe it may be increasingly challenging to continue to hire people who will maintain our company culture. Our company culture, which we believe is one of our competitive strengths, is important to providing high-quality customer service and having a productive, accountable workforce that helps keep our costs low. As we continue to grow, we may be unable to identify, hire or retain enough people who meet the above criteria, including those in management or other key positions. Our company culture could otherwise be adversely affected by our growing operations and geographic diversity. If we fail to maintain the strength of our company culture, our competitive ability and our business, results of operations and financial condition could be harmed.

Our business, results of operations and financial condition could be materially adversely affected if we lose the services of our key personnel.

Our success depends to a significant extent upon the efforts and abilities of our senior management team and key financial and operating personnel. In particular, we depend on the services of our senior management team. Competition for highly qualified personnel is intense. For example, the pendency of the Merger may make it difficult to retain and hire qualified personnel. The loss of any executive officer or other key employee without adequate replacement or the inability to attract new qualified personnel could have a material adverse effect on our business, results of operations and financial condition. We do not maintain key-person life insurance on our management team.

The requirements of being a public company may strain our resources, divert management’s attention and affect our ability to attract and retain qualified board members.

As a public company, we incur significant legal, accounting and other expenses, including costs associated with public company reporting requirements. We also have incurred and will continue to incur costs associated with the Sarbanes-Oxley Act of 2002, as amended, the Dodd-Frank Act and related rules implemented or to be implemented by the SEC and the New York Stock Exchange. The expenses incurred by public companies generally for reporting and corporate governance purposes have been increasing. We expect these rules and regulations to increase our legal and financial compliance costs and to make some activities more time-consuming and costly. These laws and regulations could also make it more difficult or costly for us to obtain certain types of insurance, including director and officer liability insurance, and we may be forced to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. These laws and regulations could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors, our board committees, or as our executive officers and may divert management’s attention. Furthermore, if we are unable to satisfy our obligations as a public company, we could be subject to delisting of our common stock, fines, sanctions and other regulatory action and potentially civil litigation.

Risks Related to Our Programs

The success of the Free Spirit Program and the Spirit Saver$ Club® program depend on the success of the Company.

The Free Spirit Program and the Spirit Saver$ Club® program depend on our continued success as a commercial airline and our continued performance under certain Free Spirit Agreements. The success or failure of our business will have a direct impact the success and the value of the Free Spirit Program and the Spirit Saver$ Club® program.

Business decisions made by the Company, including with respect to ticket prices, routes, the location of hubs, cabin designs, safety procedures, any initiatives to retain customers and otherwise, could have an adverse impact on our appeal to air travelers, which could negatively affect participation in the Free Spirit Program and the Spirit Saver$ Club® program, damage

36

our reputation or harm our relationships with the Free Spirit Partners. For instance, certain business decisions may negatively adjust the rate at which points are purchased by third parties under the terms of the applicable Free Spirit Agreement, and decisions by the Company with respect to mergers, divestitures or other corporate events may provide for termination rights of third parties under Free Spirit Agreements, each of which could have a material adverse effect on the financial and operational success, as well as the appraised value of the Free Spirit Program and the Spirit Saver$ Club® program.

The success of the Free Spirit Program and the Spirit Saver$ Club® program may be harmed by decisions or actions of our partners that are beyond our control.

The Free Spirit Program and the Spirit Saver$ Club® program depend in part on the decisions or actions of our partners. For example, issuers of our co-branded credit cards have certain rights to alter terms and conditions of the credit card accounts of their customers, including finance charges and other fees and required minimum monthly payments, in order to maintain their competitive position in the credit card industry or to comply with, among other things, regulatory guidelines, relevant law or prudent business practices. Changes in the terms of such credit card accounts may reduce the number of new accounts, the volume of credit card spend or negatively impact account retention, which in turn may reduce the number of points accrued and sold or impact the Free Spirit Program. Although issuers of our co-branded credit cards may consult the Company prior to implementing any such changes, no assurance can be given that issuers of our co-branded credit cards will not take actions that adversely affect the success of Free Spirit Program and the Spirit Saver$ Club® program.

Covenant restrictions on the Free Spirit Program and the Spirit Saver$ Club® program in our debt agreements will impose restrictions on our operations, and if we are not able to comply with such covenants, our creditors could accelerate our indebtedness or exercise other remedies.

The covenants in the indenture governing the Secured Notes contains a number of provisions that impose restrictions on the Free Spirit Program and the Spirit Saver$ Club® program which, subject to certain exceptions, limit the ability of the Company to, among other things, amend the policies and procedures of the Free Spirit Program and the Spirit Saver$ Club® program in a manner that would be reasonably expected to have a material adverse effect, compete with the Free Spirit Program and the Spirit Saver$ Club® by establishing another mileage or loyalty program (subject to certain exceptions) and sell pre-paid miles in excess of $25.0 million annually and $125.0 million in the aggregate. The indenture contains additional restrictions on the Free Spirit Program and the Spirit Saver$ Club® program, including the ability to terminate or modify certain licenses and certain material Free Spirit Agreements. The indenture also requires Spirit to maintain a minimum liquidity of at least $400.0 million on a daily basis. Such covenants are in addition to the other restrictions in the indenture, such as restrictions on the ability of the issuers and guarantors of the Secured Notes to make restricted payments, incur additional indebtedness, enter into certain transactions with affiliates, create or incur certain liens on the collateral, merge, consolidate, or sell assets, sell, transfer or otherwise convey the collateral and designate certain subsidiaries as unrestricted.

Complying with these covenants and other restrictive covenants that may be contained in any future debt agreements will limit our ability to operate our business and may limit our ability to take advantage of business opportunities that are in our long-term interest.

The failure to comply with any of these covenants or restrictions could result in a default under the indenture governing the Secured Notes or any future debt agreement, which could lead to an acceleration of the debt under such instruments and, in some cases, the acceleration of debt under other instruments that contain cross-default or cross-acceleration provisions, each of which could have a material adverse effect on the Company. In the case of an event of default, or in the event of a cross-default or cross-acceleration, we may not have sufficient funds available to make the required payments under our debt agreements.

Risks Related to Our Leverage and Liquidity

We have a significant amount of aircraft-related fixed obligations and we have incurred, and may incur in the future, significant additional debt, that could impair our liquidity and thereby harm our business, results of operations and financial condition.

The airline business is capital intensive and, as a result, many airline companies are highly leveraged. As of December 31, 2023, we had $1,667.7 million in aircraft-related debt and $1,771.4 million of other long-term debt on our consolidated balance sheet. In 2023 and 2022, we made scheduled principal payments of $337.5 million and $193.0 million on our outstanding debt obligations, respectively. In addition. during the fourth quarter of 2023, the Company early extinguished $323.3 million of outstanding fixed-rate term loans. As of December 31, 2023, we had future principal debt obligations of $3.4 billion, of which $305.2 million is due in 2024.

37

In 2023 and 2022, we paid the lessors rent of $389.6 million and $286.0 million, respectively. As of December 31, 2023, we had future aircraft and spare engine operating lease obligations of approximately $5.6 billion.

In addition, we have significant obligations for aircraft and spare engines that we have ordered from Airbus, IAE, and Pratt & Whitney for delivery over the next several years.

Our ability to pay the fixed and other costs associated with our contractual obligations will depend on our operating performance, cash flow and our ability to secure adequate financing, which will in turn depend on, among other things, the success of our current business strategy, fuel price volatility, weakening or improvement in the U.S. economy, as well as general economic and political conditions and other factors that are beyond our control. From time to time and subject to market conditions and any applicable contractual requirements, we may refinance portions of our debt, including our 2025 maturities, which, at current interest rates and market conditions, may negatively impact our interest expense or result in higher dilution. The amount of our aircraft-related fixed obligations, our obligations under our other debt arrangements, and the related need to obtain financing could have a material adverse effect on our business, results of operations and financial condition and could:

•require a substantial portion of cash flow from operations for operating lease and maintenance deposit payments, and principal and interest on our indebtedness, thereby reducing the availability of our cash flow to fund working capital, capital expenditures and other general corporate purposes;

•limit our ability to make required pre-delivery deposit payments, or PDPs, including those payable to our aircraft and engine manufacturers for our aircraft and spare engines on order;

•limit our ability to obtain additional financing to support our expansion plans and for working capital and other purposes on acceptable terms or at all;

•make it more difficult for us to pay our other obligations as they become due during adverse general economic and market industry conditions because any related decrease in revenues could cause us to have insufficient cash flows from operations to make our scheduled payments;

•reduce our flexibility in planning for, or reacting to, changes in our business and the airline industry and, consequently, place us at a competitive disadvantage to our competitors with fewer fixed payment obligations or which are subject to fewer limitations or restrictions; and

•cause us to lose access to one or more aircraft and forfeit our rent deposits if we are unable to make our required aircraft lease rental and debt payments and our lessors or lenders exercise their remedies under the lease and debt agreements, including cross default provisions in certain of our leases and mortgages.

A failure to pay our operating lease, debt and other fixed cost obligations or a breach of our contractual obligations could result in a variety of adverse consequences, including the exercise of remedies by our creditors and lessors. In such a situation, it is unlikely that we would be able to cure our breach, fulfill our obligations, make required lease or debt payments or otherwise cover our fixed costs, which would have a material adverse effect on our business, results of operations and financial condition.

Downgrades in our credit ratings could increase future debt financing costs and limit the future availability of debt financing.

Our credit ratings are important to our cost and availability of capital. The major rating agencies routinely evaluate our credit profile and assign credit ratings to us. This evaluation is based on a number of factors, which include financial strength, business and financial risk, transparency with rating agencies, and timeliness of financial reporting, as well as overall industry risk. We have experienced downgrades in our credit ratings based on our increased level of credit risk as a result of the financial impacts of the COVID-19 pandemic and a continued lack of profitability.

Beginning in 2020 with the onset of the COVID-19 pandemic and through January 2024, on occasion, our corporate credit rating and the credit ratings of our Spirit Airlines Pass Through Trust Certificates have been downgraded by Fitch, S&P Global and/or Moody's. As of January 2024, our Fitch, S&P Global and Moody's credit ratings were B-, CCC+ and Caa2, respectively.

As of January 2024, the S&P Global credit ratings of our Spirit Airlines Pass Through Trust Certificates Series 2015-1 Class A and B were BB+ and B+, respectively, and the credit ratings of our Spirit Airlines Pass Through Trust Certificates Series 2017-1 Class AA, A and B were BBB, BB+ and B, respectively. As of January 2024, the Fitch credit ratings of our Spirit

38

Airlines Pass Through Trust Certificate Series 2015-1 Class B and 2017-1 Class B were BB and the Fitch credit ratings of our Spirit Airlines Pass Through Trust Certificate Series 2017-1 Class AA was A+.

If our credit ratings were to be further downgraded, or general market conditions were to ascribe higher risk to our ratings levels, the airline industry, or us, it could increase future debt financing costs and limit the future availability of debt financing, which would have an adverse effect on our business, results of operations and financial condition.

Despite our current indebtedness levels, we may incur additional indebtedness in the future, which could further increase the risks associated with our leverage.

We may be able to incur substantial additional indebtedness, including additional secured indebtedness, in the future. Our debt agreements do not prohibit us from incurring additional unsecured indebtedness or certain secured indebtedness. If other such indebtedness is incurred in the future, our debt service obligations will increase. The more leveraged we become, the more we will be exposed to the risks created by our current substantial indebtedness.

Our ability to incur secured indebtedness is subject to compliance with certain covenants in the indenture governing the Secured Notes and, in certain circumstances, the liens securing such additional indebtedness will be permitted to be pari passu with the liens securing the Secured Notes.

To the extent that the terms of our current or future debt agreements would prevent us from incurring additional indebtedness, we may be able to obtain amendments to those agreements that would allow us to incur such additional indebtedness, and such additional indebtedness could be material.

For additional information, refer to “Notes to Consolidated Financial Statements—13. Debt and Other Obligations” and “Notes to Consolidated Financial Statements—10. Equity.”

We are highly dependent upon our cash balances and operating cash flows.

As of December 31, 2023, we have a revolving credit facility, maturing in 2025, for up to $300.0 million which was undrawn and available as of December 31, 2023. For additional information, refer to “Management's Discussion and Analysis of Financial Condition and Results of Operations” and “Notes to Consolidated Financial Statements—13. Debt and Other Obligations.” This credit facility is not adequate to finance our operations, and we will continue to be dependent on our operating cash flows and cash balances to fund our operations and to make scheduled payments on our aircraft-related fixed obligations. In addition, we have sought, and may continue to seek, financing from other available sources to fund our operations. In addition, our credit card processors are entitled to withhold receipts from customer purchases from us, under certain circumstances. If we fail to maintain certain liquidity and other financial covenants, their rights to holdback would become operative, which would result in a reduction of unrestricted cash that could be material. If we fail to generate sufficient funds from operations to meet our operating cash requirements or do not obtain a line of credit, other borrowing facility or equity financing, we could default on our operating lease and fixed obligations. Our inability to meet our obligations as they become due would have a material adverse effect on our business, results of operations and financial condition.

Our net operating losses may be limited for U.S. federal income tax purposes under Section 382 of the U.S. Internal Revenue Code.

If a corporation with net operating losses (“NOLs”) undergoes an “ownership change” within the meaning of Section 382 of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), then such corporation’s use of such “pre-change” NOLs to offset income incurred following such ownership change generally will be subject to an annual limitation specified in Section 382 of the Code. Such limitation also may apply to certain losses or deductions that are “built-in” (i.e., attributable to periods prior to the ownership change, but not yet taken into account for tax purposes) as of the date of the ownership change that are subsequently recognized. An ownership change generally occurs when there is either (i) a shift in ownership involving one or more “5% shareholders,” or (ii) an “equity structure shift” and, as a result, the percentage of stock of the corporation owned by one or more 5% shareholders (based on value) has increased by more than 50 percentage points over the lowest percentage of stock of the corporation owned by such shareholders during the “testing period” (generally the three years preceding the testing date). If the use of our net operating losses to offset our income is subject to such an annual limitation, it is possible that our cash flows, business operations or financial conditions could be adversely affected.

Risks Related to Our Securities

The issuance or sale of shares of our common stock, or rights to acquire shares of our common stock, or warrants issued to the Treasury under the PSP1, PSP2 or PSP3, could depress the trading price of our common stock and Convertible Notes.

We may conduct future offerings of our common stock, preferred stock or other securities that are convertible into or exercisable for our common stock to finance our operations or fund acquisitions, or for other purposes. In connection with our participation in PSP1, PSP2 and PSP3, we issued to the Treasury 739,089 warrants which may be exercised for shares of our common stock in consideration for the receipt of funding from the Treasury.The warrants expire in five years from the date of issuance, are transferable, have no voting rights and contain customary terms regarding anti-dilution. If the Treasury or any subsequent warrant holder exercises the warrants, the interest of our holders of common stock would be diluted and we would be partially owned by the U.S. government, which could have a negative impact on our common stock price, and which could require increased resources and attention by our management. Additionally, in 2020 we issued 9,000,000 shares pursuant to our ATM Program and in 2021 we completed the registered direct placement of 10,594,073 shares of our voting common stock. Further, we reserve shares of our common stock for future issuance under our equity incentive plans, which shares are eligible for sale in the public market to the extent permitted by the provisions of various agreements and, to the extent held by affiliates, the volume and manner of sale restrictions of Rule 144. If these additional shares are sold, or if it is perceived that they will be sold, into the public market, the price of our common stock could decline substantially. The indenture for the 4.750% convertible senior notes due 2025 (the “2025 Convertible Notes”) and the 1.00% convertible senior notes due 2026 (the “2026 Convertible Notes”, and together with the 2025 Convertible Notes, the “Convertible Notes”) does not restrict our ability to issue additional equity securities in the future. If we issue additional shares of our common stock or rights to acquire shares of our common stock, if any of our existing stockholders sells a substantial amount of our common stock, or if the market perceives that such issuances or sales may occur, then the trading price of our common stock, and, accordingly, the Convertible Notes, may significantly decline. In addition, any issuance of additional shares of common stock will dilute the ownership interests of our existing common stockholders, including holders of our Convertible Notes who have received shares of our common stock upon conversion of their Convertible Notes.

Conversion of the Convertible Notes may dilute the ownership interest of existing stockholders, including holders of the Convertible Notes who have previously converted their Convertible Notes.

At our election, we may settle Convertible Notes tendered for conversion partly or, in the case of the 2025 Convertible Notes, entirely, in shares of our common stock. As a result, the conversion of some or all of the Convertible Notes may dilute the ownership interests of existing stockholders. Any sales in the public market of the common stock issuable upon such conversion of the Convertible Notes could adversely affect prevailing market prices of our common stock and, in turn, the price of the Convertible Notes. In addition, the existence of the Convertible Notes may encourage short selling by market participants because the conversion of the Convertible Notes could depress the price of our common stock.

Provisions in the indenture governing the Convertible Notes could delay or prevent an otherwise beneficial takeover of us.

Certain provisions in the Convertible Notes and the indenture governing the Convertible Notes could make the Merger or another third party attempt to acquire us more difficult or expensive. For example, if a takeover, including the Merger, constitutes a fundamental change, then holders of the Convertible Notes will have the right to require us to repurchase their notes for cash. In addition, if a takeover, including the Merger, constitutes a make-whole fundamental change, then we may be required to temporarily increase the conversion rate. In either case, and in other cases, our obligations under the Convertible Notes and the indenture governing the Convertible Notes could increase the cost of the Merger or acquiring us or otherwise discourage a third party from acquiring us or removing incumbent management, including in a transaction that holders of the Convertible Notes or holders of our common stock may view as favorable.

The market price of our common stock has been, and may continue to be, volatile, which could cause the value of an investment in our stock to decline.

The market price of our common stock may fluctuate substantially due to a variety of factors, many of which are beyond our control, including:

•announcements, media reports, analyst reports or other publications regarding the Merger or the litigation concerning the Merger;

40

•announcements concerning our competitors, the airline industry or the economy in general;

•strategic actions by us or our competitors, such as acquisitions or restructurings;

•increased price competition;

•media reports and publications about the safety of our aircraft or the aircraft type we operate;

•new regulatory pronouncements and changes in regulatory guidelines;

•changes in the price of aircraft fuel;

•announcements concerning the availability of the type of aircraft we use;

•general and industry-specific economic conditions, including the level of inflation;

•changes in financial estimates or recommendations by securities analysts or failure to meet analysts’ performance expectations;

•sales of our common stock or other actions by investors with significant shareholdings;

•trading strategies related to changes in fuel or oil prices; and

•general market, political and economic conditions.

The stock markets in general have experienced substantial volatility that has often been unrelated to the operating performance of particular companies. These types of broad market fluctuations may adversely affect the trading price of our common stock. The price of our common stock has recently declined substantially in response to the announcement of the Injunction and statements by JetBlue related to the Merger and the Injunction. Any significant future declines in the price of our common stock could have an adverse impact on investor confidence and employee retention, which could have a material adverse effect on our business, results of operations and financial condition.

In the past, stockholders have sometimes instituted securities class action litigation against companies following periods of volatility in the market price of their securities. Any similar litigation against us could result in substantial costs, divert management’s attention and resources and harm our business or results of operations.

We may be unable to purchase the Secured Notes or the Convertible Notes upon the occurrence of an applicable change of control or other event.

Upon the occurrence of a Parent Change of Control, as defined in the indenture governing the Secured Notes, the issuers of the Secured Notes would be required to offer to purchase such notes for cash at a price equal to 101% of their aggregate principal amount, plus accrued and unpaid interest, if any, to, but not including, the repurchase date. Additionally, holders of the Convertible Notes may require us to repurchase their notes following a fundamental change, as defined in the indenture governing the Convertible Notes, at a cash repurchase price generally equal to the principal amount of the Convertible Notes to be repurchased, plus accrued and unpaid interest, if any. In addition, upon conversion, we will satisfy part or all of our conversion obligation in cash unless we elect to settle conversions solely in shares of our common stock.

Applicable law, regulatory authorities and the agreements governing our other indebtedness may restrict our ability to repurchase the Secured Notes or Convertible Notes or pay the cash amounts due upon conversion of the Convertible Notes. Moreover, the exercise by holders of the Secured Notes or Convertible Notes of the right to require the issuers to repurchase their respective notes, or the failure to repurchase such notes, could cause a default under our other debt, even if the event itself does not result in a default under such debt, due to the financial effect of such repurchase. In addition, we may not have enough available cash or be able to obtain financing at the time we are required to repurchase the Convertible Notes or the Secured Notes, or pay the cash amounts due upon conversion of the Convertible Notes. Therefore, we cannot assure you that sufficient funds will be available when necessary to make any required repurchases.

In addition, the indenture governing the Secured Notes sets forth certain Mandatory Prepayment Events, as defined in the indenture governing the Secured Notes. Upon the occurrence of any such Mandatory Prepayment Event, we would be required to prepay the Secured Notes pro rata to the extent of any net cash proceeds received in connection with such event, at a price equal to 100% of the principal amount to be redeemed plus an applicable premium and accrued and unpaid interest, if any, thereon to, but excluding, the prepayment date. Our failure to complete any such mandatory prepayment would result in a

41

default under the indenture governing the Secured Notes. Such a default may, in turn, constitute a default under any other of our debt agreements that may then be outstanding.

Finally, the indenture governing the Secured Notes sets forth certain Mandatory Repurchase Offer Events, as defined in the indenture governing the Secured Notes. Upon the occurrence of any such Mandatory Repurchase Offer Event, we would be required to offer to repurchase the Secured Notes pro rata to the extent of any net cash proceeds received in connection with such event, at a price equal to 100% of the principal amount to be repurchased plus accrued and unpaid interest thereon to, but excluding, the repurchase date. Our failure to discharge this obligation would result in a default under the indenture governing the Secured Notes. Such a default may, in turn, constitute a default under other of our debt agreements that may then be outstanding.

The indenture governing the Secured Notes impose certain restrictions which may adversely affect our business and liquidity.

The indenture governing the Secured Notes imposes certain restrictions on the issuers of the Secured Notes and certain guarantors. These restrictions limit their ability to, among other things: (i) make restricted payments, (ii) incur additional indebtedness, (iii) create certain liens on the collateral, (iv) sell or otherwise dispose of the collateral and (v) consolidate, merge, sell or otherwise dispose of all or substantially all of the issuers’ assets, among other restrictions. As a result of these restrictions, we may be limited in how we conduct our business, in our ability to compete effectively or in our ability to implement changes or take advantage of business opportunities—including by making strategic acquisitions, investments or alliances, restructuring our organization or financing capital needs—that would be in our interest. We may also be unable to raise additional indebtedness or equity financing to operate during general economic or business downturns.

If securities or industry analysts do not publish research or reports about our business, or publish negative reports about our business, our stock price and trading volume could decline.

The trading market for our common stock depends in part on the research and reports that securities or industry analysts publish about us or our business. If one or more of the analysts who cover us downgrade our stock or publish inaccurate or unfavorable research about our business, our stock price would likely decline. If one or more of these analysts cease coverage of our company or fail to publish reports on us regularly, demand for our stock could decrease, which might cause our stock price and trading volume to decline.

Our anti-takeover provisions may delay or prevent a change of control, which could adversely affect the price of our common stock.

Our amended and restated certificate of incorporation and amended and restated bylaws contain provisions that may make it difficult to remove our board of directors and management and may discourage or delay “change of control” transactions, which could adversely affect the price of our common stock. These provisions include, among others:

•our board of directors is divided into three classes, with each class serving for a staggered three-year term, which prevents stockholders from electing an entirely new board of directors at an annual meeting;

•actions to be taken by our stockholders may only be effected at an annual or special meeting of our stockholders and not by written consent;

•special meetings of our stockholders can be called only by the Chairman of the Board or by our corporate secretary at the direction of our board of directors; and

•advance notice procedures that stockholders must comply with in order to nominate candidates to our board of directors and propose matters to be brought before an annual meeting of our stockholders may discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to obtain control of our company.

Our corporate charter and bylaws include provisions limiting voting by non-U.S. citizens and specifying an exclusive forum for stockholder disputes.

To comply with restrictions imposed by federal law on foreign ownership of U.S. airlines, our amended and restated certificate of incorporation and amended and restated bylaws restrict voting of shares of our common stock by non-U.S. citizens. The restrictions imposed by federal law currently require that no more than 25% of our stock be voted, directly or indirectly, by persons who are not U.S. citizens, and that our president and at least two-thirds of the members of our board of directors and senior management be U.S. citizens. Our amended and restated bylaws provide that the failure of non-U.S.

42

citizens to register their shares on a separate stock record, which we refer to as the “foreign stock record,” would result in a suspension of their voting rights in the event that the aggregate foreign ownership of the outstanding common stock exceeds the foreign ownership restrictions imposed by federal law.

Our amended and restated bylaws further provide that no shares of our common stock will be registered on the foreign stock record if the amount so registered would exceed the foreign ownership restrictions imposed by federal law. If it is determined that the amount registered in the foreign stock record exceeds the foreign ownership restrictions imposed by federal law, shares will be removed from the foreign stock record in reverse chronological order based on the date of registration therein, until the number of shares registered therein does not exceed the foreign ownership restrictions imposed by federal law. As of December 31, 2023, we believe we were in compliance with the foreign ownership rules.

As of December 31, 2023, there are no shares of non-voting common stock outstanding. When shares of non-voting common stock are outstanding, the holders of such stock may convert such shares, on a share-for-share basis, in the order reflected on our foreign stock record as shares of common stock are sold or otherwise transferred by non-U.S. citizens to U.S. citizens.

Our amended and restated certificate of incorporation also specifies that the Court of Chancery of the State of Delaware shall be the exclusive forum for substantially all disputes between us and our stockholders. Because the applicability of the exclusive forum provision is limited to the extent permitted by applicable law, we do not intend for the exclusive forum provision to apply to suits brought to enforce any duty or liability created by the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction, and acknowledge that federal courts have concurrent jurisdiction over all suits brought to enforce any duty or liability created by the Securities Act. We note that there is uncertainty as to whether a court would enforce the provision as it applies to the Securities Act and that investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder. This provision may have the effect of discouraging lawsuits against our directors and officers.

We do not intend to pay cash dividends for the foreseeable future.

We have never declared or paid cash dividends on our common stock. We currently intend to retain our future earnings, if any, to finance the further development and expansion of our business and fund share repurchases under programs approved by our Board of Directors. We do not intend to pay cash dividends in the foreseeable future. The Merger Agreement restricts us from declaring or paying dividends without JetBlue's consent until the Merger is completed or the Merger Agreement is terminated. Any future determination to pay dividends will be at the discretion of our board of directors and will depend on our financial condition, results of operations, capital requirements, restrictions contained in current or future financing instruments, business prospects and such other factors as our Board of Directors deems relevant. The timing of any share repurchases under share repurchase programs will depend upon market conditions, our capital allocation strategy and other factors. Additionally, the Merger Agreement restricts us from repurchasing shares of our common stock without JetBlue’s consent until the Merger is completed or the Merger Agreement is terminated.

ITEM 1C.    CYBERSECURITY

The Company’s cybersecurity program is designed to secure the continuity of operations and protect the privacy of company, guest and team member data. The Company uses multiple layers of security controls and unique threat intelligence within the “Center for Internet Security v8 Cybersecurity Framework” across five core security functions: Identify risks and threats, Protect, Detect, Respond and Recover. In addition, the Company requires that its employees complete annual compliance training on cybersecurity and online habits.

The Company’s cybersecurity program is managed by a dedicated cybersecurity function reporting to the Chief Information Security Officer (“CISO”) who reports to the Chief Information Officer (“CIO”) and is responsible for the Company’s cybersecurity strategy, policies, standards, architecture and process. The CISO has over 20 years of executive experience in IT operations and security, primarily in the airline industry, and maintains several active certifications in Risk and Information Security including CIPPUS, CISSP-ISSMP, CISM, CRISC, and CISSP. The program includes periodic and ad hoc reporting on relevant developments, including monitoring, prevention, detection, mitigation and remediation of the current cybersecurity landscape as well as reporting on any cybersecurity incidents to the Company’s CEO and the Safety, Security and Operations Committee of the Board of Directors, which has oversight of management’s cybersecurity function. The CISO also engages external government and commercial expertise to continuously evaluate, test and adapt the program. External vendors participate in in-depth security assessments based on the Company’s vendor management security policy.

Currently, the Company is not aware of any material risks from cybersecurity threats that have materially affected or are reasonably likely to materially affect the Company’s operations. However, the nature of potential cybersecurity risks and threats are uncertain, and any future incidents, outages or breaches could have a material adverse effect on the Company’s business strategy, results of operations or financial condition.

ITEM 2.    PROPERTIES

Aircraft

As of December 31, 2023, we operated a fleet of 205 aircraft as detailed in the following table:

Aircraft Type	Seats	Average Age (years)	Number of Aircraft	Number Owned	Number Leased(1)
A319	145	16.9	19	17	2
A320ceo	182	9.2	64	27	37
A320neo	182	2.7	84	4	80
A321ceo	228	7.0	30	25	5
A321neo	235	0.4	8	—	8
		6.6	205	73	132

(1) Includes 15 aircraft recorded as failed sale-leaseback transactions. Refer to “Notes to Consolidated Financial Statements—13. Debt and Other Obligations" and "Notes to Consolidated Financial Statements—14. Leases" for additional information.

On December 20, 2019, we entered into an A320 NEO Family Purchase Agreement with Airbus for the purchase of 100 new Airbus A320neo family aircraft, with options to purchase up to 50 additional aircraft. This agreement included a mix of Airbus A319neo, A320neo and A321neo aircraft. On July 31, 2023, we entered into Amendment No. 6 (the “Amendment”) to the A320 NEO Family Purchase Agreement. The Amendment converts the remaining A319neo aircraft to be delivered under the Airbus Purchase Agreement to A321neo aircraft. The Amendment also (i) defers certain A320neo aircraft deliveries from 2024 to 2025 and later years, (ii) extends delivery dates for certain A320neo and A321neo aircraft deliveries from 2025-2027 to 2025-2029 and (iii) adjusts the timing of option aircraft delivery dates from 2026-2028 to 2027-2029. In addition, the Amendment creates a more equal distribution of aircraft deliveries and option rights across the delivery periods. As of December 31, 2023, our firm aircraft orders consisted of 99 A320 family aircraft with Airbus, including A320neos and A321neos, with deliveries expected through 2029. As of December 31, 2023, we had secured financing for 18 aircraft, scheduled for delivery from Airbus through 2025, which will be financed through sale-leaseback transactions. In addition, we had 22 direct operating leases for A321neos with third-party lessors, with deliveries expected through 2025. During the third

44

quarter of 2021, we entered into an Engine Purchase Support Agreement which requires us to purchase a certain number of spare engines in order to maintain a contractual ratio of spare engines to aircraft in the fleet. As of December 31, 2023, we were committed to purchase 19 PW1100G-JM spare engines, with deliveries through 2029.

During the fourth quarter of 2022, we made the decision to accelerate the retirement of 29 of our A319 aircraft. During the twelve months ended December 31, 2023, we completed the sale of 12 A319 airframes and 20 A319 engines. The remaining A319 aircraft subject to the sale agreement remain in service and will continue to operate until immediately before the sale of the aircraft. Excluding the A319 aircraft to be sold, the average age of our fleet would have been 5.5 years as of December 31, 2023. In addition, we are scheduled to take delivery of 121 new Airbus A320-family aircraft through 2029, potentially making ours the youngest fleet in the United States. Refer to “Notes to Consolidated Financial Statements— 1. Summary of Significant Accounting Policies" for additional information.

Ground Facilities    

We lease all of our facilities at each of the airports we serve, with the exception of our aircraft maintenance hangar in Detroit, which we own and operate on leased land. Our leases for terminal passenger service facilities, which include ticket counter and gate space, operations support areas and baggage service offices, generally have a term ranging from month-to-month to 24 years, and contain provisions for periodic adjustments of lease rates. We also are responsible for maintenance, insurance and other facility-related expenses and services. We also have entered into use agreements at the airports we serve that provide for the non-exclusive use of runways, taxiways and other airfield facilities. Landing fees paid under these agreements are based on the number of landings and weight of the aircraft.

As of December 31, 2023, Ft. Lauderdale/Hollywood International Airport (FLL) remained our single largest airport served, with approximately 22% of our capacity operating through FLL during 2023. We operate primarily out of Terminals 3 and 4 at FLL. We currently use up to thirteen gates simultaneously at Terminal 3 and Terminal 4. We have preferential access to six of the Terminal 4 gates, preferential access to four of the Terminal 3 gates, common use access to the four airport controlled Terminal 4 gates, and common use access to the one airport controlled Terminal 3 gate. Other airports through which we conduct significant operations include Orlando International Airport (MCO), McCarran International Airport (LAS), Hartsfield-Jackson Atlanta International Airport (ATL) and Los Angeles International Airport (LAX).

Our largest maintenance facility is a hangar currently located at Detroit, Michigan. The lease with the Detroit, Michigan airport authority expires in September 2032. Our second largest maintenance facility is a hangar and warehouse currently located at Houston, Texas. As of December 31, 2023, we also conduct additional maintenance operations in leased facilities in Fort Lauderdale, Florida; Chicago, Illinois; Atlantic City, New Jersey; Dallas, Texas; Las Vegas, Nevada; Orlando, Florida; Atlanta, Georgia; Myrtle Beach, South Carolina; Philadelphia, Pennsylvania; Baltimore, Maryland; Miami, Florida; Tampa, Florida and Los Angeles, California.

Our principal executive offices and headquarters are located in a leased facility at 2800 Executive Way, Miramar, Florida 33025, consisting of approximately 56,000 square feet. The lease for this facility expires in January 2025. In January 2014, we expanded our principal executive offices and headquarters by leasing an additional facility located at 2844 Corporate Way, Miramar, Florida 33025, consisting of approximately 15,000 square feet. The lease for this facility expires in January 2025. In March 2018, we added approximately 26,000 square feet of office space at 2877-2899 N Commerce Parkway, Miramar, FL 33025 to further support the corporate headquarters. The lease on this space expires in January 2025.

During the fourth quarter of 2019, we purchased an 8.5-acre parcel of land and entered into a 99-year lease agreement for the lease of a 2.6-acre parcel of land, in Dania Beach, Florida, where we are building a new headquarters campus and a 200-unit residential building. During the first quarter of 2022, we began building our new headquarters campus and a 200-unit residential building with an expected completion during the first quarter of 2024.

ITEM 3.    LEGAL PROCEEDINGS

We are subject to commercial litigation claims and to administrative and regulatory proceedings and reviews that may be asserted or maintained from time to time. We believe the ultimate outcome of pending lawsuits, proceedings and reviews will not, individually or in the aggregate, have a material adverse effect on our financial position, liquidity, or results of operations. In making a determination regarding accruals, using available information, we evaluate the likelihood of an unfavorable outcome in legal or regulatory proceedings and assessments to which we are a party and record a loss contingency when it is probable a liability has been incurred and the amount of the loss can be reasonably estimated. These subjective determinations are based on the status of such legal or regulatory proceedings, the merits of our defenses, and consultation with legal counsel. Actual outcomes of these legal and regulatory proceedings may materially differ from our current estimates. It is possible that

45

resolution of one or more of the legal matters currently pending or threatened could result in losses material to our consolidated results of operations, liquidity or financial condition.

In 2017, a purported class action lawsuit was filed against us in the Eastern District of New York ("EDNY"), styled Cox, et al. v. Spirit Airlines, Inc., alleging state-law claims of breach of contract, unjust enrichment and fraud relating to our practice of charging fees for ancillary products and services. The original action was dismissed by the EDNY, however, following the plaintiff’s appeal to the Second Circuit, the case was remanded to the EDNY for further review on the breach of contract claim. A hearing on our Motion for Summary Judgment and plaintiff’s Motion for Class Certification was held on December 10, 2021. The EDNY granted the plaintiff’s class certification motion on March 29, 2022. We subsequently filed a motion for reconsideration on April 26, 2022 and an oral argument was held on May 19, 2022. The EDNY denied our motion for reconsideration on February 14, 2023. On April 3, 2023, we moved to compel arbitration of and/or dismiss certain class members’ claims for lack of personal jurisdiction. Trial was set to begin on January 16, 2024. However, in June 2023, we reached a tentative settlement in mediation for a maximum amount of $8.3 million. The EDNY issued a preliminary approval order on September 21, 2023, and the final approval hearing was held on December 11, 2023. The total amount paid depends on a number of factors, including participation of class members and any conditions on the settlement approved by the EDNY. Currently, our best estimate of the probable loss associated with the settlement is $6.0 million, and we have recorded this amount in other operating expenses within our consolidated statements of operations.

On February 27, 2023, ALPA filed a grievance against us claiming that we violated the collective bargaining agreement (“CBA”) by excluding its pilots from our retention award programs granted as part of the former merger agreement with Frontier Airlines (the "Former Frontier Merger Agreement") and the Merger Agreement with JetBlue. On September 8, 2023, we filed a motion to dismiss the grievance, as we do not believe that ALPA filed the grievance within the timeline set forth in the CBA. As of December 31, 2023, the potential outcomes of this claim cannot be determined and an estimate of the reasonably possible loss or range of loss cannot be made.

Following an audit by the IRS related to the collection of federal excise taxes on optional passenger seat selection charges covering the second quarter of 2018 through the fourth quarter of 2020, on March 31, 2022, we were assessed $34.9 million. On July 19, 2022, the assessment was reduced to $27.5 million. We believe we have defenses available and intend to challenge the assessment; therefore, we have not recognized a loss contingency.

ITEM 5.    MARKET FOR REGISTRANT'S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

Our common stock is listed and traded on the NYSE under the symbol "SAVE." As of January 26, 2024, there were approximately 67 holders of record of our common stock. Because many of our shares are held by brokers and other institutions on behalf of stockholders, we are unable to estimate the total number of stockholders represented by the holders.

The information under the caption “Equity Compensation Plan Information” in our 2024 Proxy Statement is incorporated herein by reference.

Dividend Policy

We have never declared or paid, and do not anticipate declaring or paying, any cash dividends on our common stock. Any future determination as to the declaration and payment of dividends, if any, will be at the discretion of our board of directors and will depend on then existing conditions, including our financial condition, operating results, contractual restrictions, capital requirements, business prospects and other factors our board of directors may deem relevant.

Our Repurchases of Equity Securities

The following table reflects our repurchases of our common stock during the fourth quarter of 2023. Repurchases of equity securities during the period include repurchases made from employees who received restricted stock awards, market share awards and performance share awards. All employee stock repurchases were made at the election of each employee pursuant to an offer to repurchase by us. In each case, the shares repurchased constituted the portion of vested shares necessary to satisfy tax withholding requirements.

ISSUER PURCHASES OF EQUITY SECURITIES
Period	Total Number of Shares Purchased	Average Price Paid per Share		Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs	Approximate Dollar Value of Shares that May Yet be Purchased Under Plans or Programs
October 1-31, 2023	1,052	$	16.31	—	$	—
November 1-30, 2023	—	—		—	—
December 1-31, 2023	55,906	16.31		—	—
Total	56,958	$	16.31	—

During the first three quarters of 2023, we repurchased approximately 85 thousand shares for a total of $1.7 million. Repurchases of equity securities during this period include repurchases made from employees who received restricted stock awards, market share awards or performance share awards.

ITEM 7.    MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

You should read the following discussion of our financial condition and results of operations in conjunction with the consolidated financial statements and the notes thereto included elsewhere in this annual report. Our discussion and analysis of fiscal year 2023 compared to fiscal year 2022 is included herein. Unless expressly stated otherwise, for discussion and analysis of fiscal year 2021 items and fiscal year 2022 compared to fiscal year 2021, please refer to Item 7 of Part II, "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022, which was filed with the United States Securities and Exchange Commission on February 6, 2023 and is incorporated herein by reference.

We evaluate our financial performance utilizing various accounting principles generally accepted in the United States of America (“GAAP”) and non-GAAP financial measures, including Adjusted CASM and Adjusted CASM ex-fuel. These non-GAAP financial measures are provided as supplemental information to the financial information presented in this annual report that is calculated and presented in accordance with GAAP and these non-GAAP financial measures are presented because management believes that they supplement or enhance management’s, analysts’ and investors’ overall understanding of our underlying financial performance and trends and facilitate comparisons among current, past and future periods.

Because the non-GAAP financial measures are not calculated in accordance with GAAP, they should not be considered superior to and are not intended to be considered in isolation or as a substitute for the related GAAP financial measures presented in this annual report and may not be the same as or comparable to similarly titled measures presented by other companies due to possible differences in the method of calculation and in the items being adjusted. We encourage investors to review our financial statements and other filings with the Securities and Exchange Commission in their entirety and not to rely on any single financial measure.

The information below provides an explanation of certain adjustments reflected in the non-GAAP financial measures and shows a reconciliation of non-GAAP financial measures reported in this annual report to the most directly comparable GAAP financial measures. Within the financial tables presented, certain columns and rows may not add due to the use of rounded numbers. Per unit amounts presented are calculated from the underlying amounts.

Operating expenses per available seat mile (“CASM”) is a common metric used in the airline industry to measure an airline’s cost structure and efficiency. We exclude loss on disposal of assets, special charges (credits) and a litigation loss contingency recorded in the second quarter of 2023 to determine Adjusted CASM. We believe that also excluding aircraft fuel and related taxes ("Adjusted CASM ex-fuel") from certain measures is useful to investors because it provides an additional measure of management’s performance excluding the effects of a significant cost item over which management has limited influence and increases comparability with other airlines that also provide a similar metric.

2023 Year in Review

JetBlue Merger

On July 28, 2022, we entered into the “Merger Agreement with JetBlue and Merger Sub, pursuant to which and subject to the terms and conditions therein, Merger Sub will merge with and into Spirit, with Spirit continuing as the surviving entity. As a result of the Merger, each existing share of Spirit's common stock (except for dissenting shares, treasury stock, and shares of Spirit's common stock owned by JetBlue, Merger Sub or any of their respective wholly owned subsidiaries), will be converted into the right to receive an amount in cash per share, without interest, equal to the Merger Consideration. If an aggregate of $1.15 of Additional Prepayment Amounts has been paid out before consummation or termination of the Merger, Spirit stockholders will thereafter continue to receive monthly Additional Prepayments, at the same $0.10 per month rate until the transaction closes or the Merger Agreement is terminated. The Merger Agreement becomes unilaterally terminable by either JetBlue or Spirit after July 24, 2024.

JetBlue will pay or cause to be paid the Approval Prepayment Amount to Spirit stockholders as of the record date established by Spirit for the special meeting to approve the Merger Agreement within five business days following such Spirit stockholder approval. Thereafter, on or prior to the last business day of each month beginning after December 31, 2022 until the earlier of the Closing or termination of the Merger Agreement, JetBlue will also pay or cause to be paid the Additional Prepayment Amount to Spirit stockholders as of a record date not more than five business days prior to the last business day of such month. Payments made from JetBlue to Spirit stockholders do not impact our results of operations or cash flows.

50

On October 19, 2022, Spirit’s stockholders approved the Merger Agreement at a special meeting of stockholders. The record date for both the Spirit’s special meeting and the Approval Prepayment was September 12, 2022. In accordance with the terms of the Merger Agreement, on October 26, 2022, JetBlue paid the Spirit stockholders the Approval Prepayment Amount of $2.50 per share. Additionally, beginning January 2023, JetBlue paid on a monthly basis the Additional Prepayments of $0.10 per share of common stock to all Spirit stockholders as of each record date per the agreement.

Due to the payment of the Approval Prepayment and each of the Additional Prepayment Amounts, in accordance with the terms of the respective debt indentures and warrant agreements, we announced related adjustments to the conversion rates of our convertible notes due 2025 and our convertible notes due 2026 as well as adjustments to the exercise prices and warrant shares of the PSP1, PSP2 and PSP3 warrants outstanding. As of December 31, 2023, the conversion rates of the convertible notes due 2025 and 2026 were 94.9262 and 24.6649 shares of voting common stock per $1,000 principal amount of convertible notes, respectively. In addition, as of December 31, 2023, the exercise prices of the PSP1, PSP2 and PSP3 warrants were $11.663, $20.229 and $30.196, respectively and the number of warrant shares issuable upon the exercise of the PSP1, PSP2 and PSP3 warrants were adjusted to 628,725.19, 166,292.37 and 97,219.73, respectively.

Completion of the Merger is subject to the satisfaction or waiver of certain closing conditions, including, among other things: (1) approval of the transactions by Spirit’s stockholders, which was received on October 19, 2022; (2) receipt of applicable regulatory approvals, including approvals from the U.S. Federal Communications Commission, the U.S. Federal Aviation Administration and the U.S. Department of Transportation and the expiration or early termination of the statutory waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and other competition laws, and other required regulatory approvals; (3) the absence of any law or order prohibiting the consummation of the transactions; and (4) the absence of any material adverse effect (as defined in the Merger Agreement) on Spirit.

On March 7, 2023, the DOJ filed suit to block the Merger and a trial was held in late 2023. On January 16, 2024, the District Court granted the Injunction. On January 19, 2024, Spirit and JetBlue filed a notice of appeal to reverse the District Court's decision and allow Spirit and JetBlue to complete the Merger. On January 25, 2024, JetBlue made a public filing stating that certain closing conditions required by the Merger Agreement may not be satisfied prior to the outside dates set forth in the Merger Agreement and, accordingly, the Merger Agreement may be terminable on and after January 28, 2024. We do not believe there is a basis for terminating the Merger Agreement, and we will continue to abide by all of our obligations under the Merger Agreement. On January 29, 2024, Spirit and JetBlue filed a request with the Court of Appeals seeking an expedited schedule for their appeal. On February 2, 2024, the Court of Appeals granted our motion, stating it would hear arguments in June 2024.

In addition, Spirit has agreed, among other things, that neither it nor any of its directors, officers, employees and representatives will (1) solicit alternative transactions, (2) participate in any discussions or negotiations relating to alternative transactions, (3) furnish any non-public information in connection with alternative transactions or (4) enter into any agreement relating to alternative transactions, except under limited circumstances described in the Merger Agreement. However, in certain circumstances, Spirit may terminate the Merger Agreement to enter into a definitive agreement for a Superior Proposal (as defined in the Merger Agreement). In addition, Spirit, JetBlue and Merger Sub each make certain customary representations, warranties and covenants, as applicable, in the Merger Agreement.

The Merger Agreement contains certain termination rights for Spirit and JetBlue, including, without limitation, a right for either party to terminate if the Merger is not consummated on or before July 28, 2023 (the "Outside Date"), subject to certain automatic extensions up to July 24, 2024 if needed to obtain regulatory approvals. Since all regulatory approvals required to consummate the Merger were not obtained as of January 28, 2023, the current Outside Date has been automatically extended to July 24, 2024. Upon the termination of the Merger Agreement under specified circumstances, Spirit will be required to pay JetBlue a termination fee of $94.2 million. Upon the termination of the Merger Agreement by JetBlue because of a material uncured breach by Spirit of the Merger Agreement, Spirit will be required to pay JetBlue an amount equal to the sum of all amounts paid by JetBlue to the Spirit stockholders. Upon the termination of the Merger Agreement for failure to obtain antitrust regulatory clearance, JetBlue will be required to pay (i) to Spirit, $70.0 million, and (ii) to the Spirit stockholders, the excess of (A) $400.0 million minus (B) the sum of the Approval Prepayment Amount and all Additional Prepayment Amounts previously paid by JetBlue to the Spirit stockholders.

Pratt & Whitney

On July 25, 2023, RTX Corporation, parent company of Pratt & Whitney, announced that it had determined that a rare condition in the powdered metal used to manufacture certain engine parts will require accelerated inspection of the GTF fleet, which powers our A320neo family of aircraft.

51

In September 2023, Pratt & Whitney notified us that all the geared turbofan GTF neo engines in our fleet, including the engines slotted for future aircraft deliveries, for a yet to be determined period, are subject to the inspection and possible replacement, of the powdered metal high-pressure turbine and compressor discs. In addition, Pratt & Whitney issued a SI, requiring accelerated engine removals and inspections covering the initial tranche of operational engines, no later than September 15, 2023. As of December 31, 2023, in accordance with the SI issued by Pratt & Whitney, we have removed five engines from service, three of which are currently awaiting induction for inspection.

For the remaining engines, Pratt & Whitney has provided an initial analysis on an inspection and removal schedule for these engines. In addition, to the 5 engines removed from service, we had 12 neo aircraft grounded as of December 31, 2023 for reliability, durability, and inspection requirements combined. For 2024, we had an average of 13 grounded neo aircraft in January 2024, and we expect the average number of grounded neo aircraft will increase to approximately 40 in December 2024, averaging approximately 25 grounded for the full year. We currently estimate the majority of affected engines will require removal and inspection in 2024, but will continue through 2026, based on SBs issued by Pratt & Whitney and related airworthiness directives issued by the FAA.

The temporary removal of engines from service is expected to drive a significant decrease in our near-term growth projections. We have reduced capacity in amounts and timing commensurate with the initially scheduled removal and inspection of these impacted engines, however, we continue to assess the impact on our future capacity plans. Pratt & Whitney stated that they are focused on addressing the challenges arising from the powdered metal manufacturing issue and will proactively take steps to support and mitigate the operational impact to its customers. We are in discussions with Pratt & Whitney regarding compensation for the loss of utilization; however, the amount, timing, or structure of the compensation that will be agreed upon is not yet known.

Summary of Results

During 2023, we generated a pre-tax loss of $558.6 million and a net loss of $447.5 million, $(4.10) per share, compared to a pre-tax loss of $700.7 million and a net loss of $554.2 million, $(5.10) per share, in 2022. The decrease in pre-tax loss was primarily driven by a decrease in special charges, year over year, as well as a decrease in aircraft fuel expense driven by a 15.8% decrease in fuel price per gallon, period over period. These decreases were partially offset by an increase in salaries, wages and benefits expense as compared to the prior year period. In addition, the reduced net loss reflects an increase in operating revenues due to a 13.7% increase in our traffic and a 14.6% increase in our capacity, as compared to 2022.

For the year ended December 31, 2023, we had a negative operating margin of 9.2% on $5,362.5 million in operating revenues. TRASM in 2023 was 9.63 cents, a decrease of 7.8% compared to the prior year. Total revenue per passenger flight segment decreased 7.7%, year over year, from $131.78 to $121.58. Fare revenue per passenger flight segment decreased 17.0%, while non-ticket revenue per passenger flight segment increased by 0.9%, as compared to the prior year.

Our operating cost structure is a primary area of focus and is at the core of our ULCC business model. Our unit operating costs continue to be among the lowest of any airline in the United States. During 2023, our Adjusted CASM ex-fuel was 7.06 cents as compared to 6.73 cents for 2022. The increase on a per-ASM basis was primarily due to increases in salaries, wages and benefits expense and aircraft rent expense, partially offset by a decrease in depreciation and amortization expense.

During 2023, we added 4 new destinations: Charleston, South Carolina, Norfolk, Virginia, San Jose, California and Tulum, Mexico. During 2023, we grew our fleet of Airbus single-aisle aircraft from 194 to 205 aircraft as we took delivery of 10 aircraft under sale-leaseback transactions and 13 aircraft under direct operating leases and sold 12 A319 aircraft. We also took delivery of 4 new engines through cash purchases. As of December 31, 2023, our 205 Airbus A320-family aircraft fleet was comprised of 19 A319ceos, 64 A320ceos, 84 A320neos, 30 A321ceos and 8 A321neos. As of December 31, 2023, we owned 73 aircraft, of which 29 aircraft were financed through fixed-rate long-term debt, 27 aircraft were financed through enhanced equipment trust certificates ("EETCs") and 17 were purchased off lease. As of December 31, 2023, we had 132 leased aircraft, of which 117 aircraft were financed under operating leases and 15 aircraft would have been deemed finance leases resulting in failed sale-leaseback transactions. As of December 31, 2023, our aircraft orders from Airbus consisted of 99 A320 family aircraft scheduled for delivery through 2029. In addition, as of December 31, 2023, we had secured financing for 22 aircraft to be leased directly from third-party lessors, scheduled for delivery through 2025.

Operating Revenues

Our operating revenues are comprised of passenger revenues and other revenues.

Passenger revenues

52

    Fare revenues. Tickets sold are initially deferred within air traffic liability on our consolidated balance sheet. Passenger fare revenues are recognized at time of departure when transportation is provided. Generally, all tickets sold by us are nonrefundable. Fare revenues are recorded within passenger revenues on our consolidated statement of operations. Refer to our disaggregated revenue table within “Notes to Consolidated Financial Statements— 1. Summary of Significant Accounting Policies."

Customers may elect to change or cancel their itinerary prior to the date of departure. For changes, a service charge is recognized at time of departure of newly scheduled travel and is deducted from the face value of the original purchase price of the ticket, and the original ticket becomes invalid. For cancellations, a service charge is assessed and the amount remaining after deducting the service charge is called a credit shell. For credit shells that we estimate are not likely to be used prior to expiration, we recognize the associated value proportionally during the period over which the remaining credit shells may be used. Estimating the amount of credits that will go unused involves some level of subjectivity and judgment and can be impacted by several factors including, but not limited to, changes to our ticketing policies, changes to our refund, exchange, and credit shell policies, and economic factors.

    Non-fare revenues. Our most significant non-fare revenues generally include revenues generated from air travel-related services paid for baggage, passenger usage fees, advance seat selection and itinerary changes. These ancillary items are deemed part of the single performance obligation of providing passenger transportation and as such, are recognized in non-fare revenues within passenger revenues on our consolidated statement of operations. Refer to our disaggregated revenue table within “Notes to Consolidated Financial Statements— 1. Summary of Significant Accounting Policies." Substantially all of our passenger non-fare revenues are recognized at time of departure when transportation is provided.

Passenger revenues are generally recognized once the related flight departs. Accordingly, the value of tickets and non-fare revenues sold in advance of travel is included under our current liabilities as “air traffic liability,” or ATL, until the related air travel is provided. An unused ticket expires at the date of scheduled travel, at which time a service charge is assessed, and is recognized as revenue at the date of scheduled travel.

Guests may earn points based on their spending with the Free Spirit affinity credit card program which we have an agreement to sell points. The contract to sell points under this agreement has multiple performance obligations, as discussed below.

Our co-branded credit card agreement provides for joint marketing where cardholders earn points for making purchases using co-branded cards. During 2023, we extended our agreement with the administrator of the Free Spirit affinity credit card program through December 31, 2028. We account for this agreement consistently with the accounting method that allocates the consideration received to the individual products and services delivered. The value is allocated based on the relative stand-alone selling prices of those products and services, which generally consists of (i) points to be awarded, (ii) airline benefits and (iii) licensing of brand and access to member lists and (iv) advertising and marketing efforts. We determined the estimate of the stand-alone selling prices by considering discounted cash flow analysis using multiple inputs and assumptions, including: (1) the expected number of points awarded and number of points redeemed, (2) the estimated stand-alone selling price of the award travel obligation and airline benefits, (3) licensing of brand and access to member lists and (4) the costs of advertising and marketing efforts. 

Other revenues

Other revenues primarily consist of the marketing component of the sale of loyalty points to our credit card partner and commissions revenue from the sale of various items such as hotels and rental cars.

Substantially all of our revenues are denominated in U.S. dollars. We recognize revenues net of certain taxes and airport passenger fees, which are collected by us on behalf of airports and governmental agencies and remitted to the applicable governmental entity or airport on a periodic basis. These taxes and fees include U.S. federal transportation taxes, federal security charges, airport passenger facility charges and foreign arrival and departure taxes. These items are collected from customers at the time they purchase their tickets, but are not included in our revenues. Upon collection from the customer, we record a liability within other current liabilities on our consolidated balance sheets and relieve the liability when payments are remitted to the applicable governmental agency or airport.

Operating Expenses

Our operating expenses consist of the following line items.

53

Aircraft Fuel. Aircraft fuel expense includes the cost of jet fuel, related federal taxes, fueling into-plane fees and transportation fees. It also includes realized and unrealized gains and losses arising from activity on our fuel derivatives, if any.

Salaries, Wages and Benefits. Salaries, wages and benefits expense includes the salaries, hourly wages, bonuses and equity compensation paid to employees for their services, as well as the related expenses associated with employee benefit plans and employer payroll taxes.

Landing Fees and Other Rents. Landing fees and other rents include both fixed and variable facilities expenses, such as the fees charged by airports for the use or lease of airport facilities, overfly fees paid to other countries and the monthly rent paid for our headquarters facility.

Aircraft Rent. Aircraft rent expense consists of all minimum lease payments under the terms of our aircraft and spare engine lease agreements recognized on a straight-line basis. Aircraft rent expense also includes supplemental rent. Supplemental rent is primarily made up of probable and estimable return condition obligations on leased aircraft. As of December 31, 2023, 117 (excluding 15 aircraft that would have been deemed finance leases resulting in failed sale-leaseback transactions) of our 205 aircraft and 6 of our 34 spare engines are financed under operating leases.

Depreciation and Amortization. Depreciation and amortization expense includes the depreciation of fixed assets we own and leasehold improvements. It also includes the amortization of capitalized software costs and heavy maintenance. Under the deferral method, the cost of our heavy maintenance is capitalized and amortized on a straight-line or usage basis until the earlier of the next estimated heavy maintenance event or the remaining lease term.

Maintenance, Materials and Repairs. Maintenance, materials and repairs expense includes parts, materials, repairs and fees for repairs performed by third-party vendors and in-house mechanics required to maintain our fleet. It excludes direct labor cost related to our own mechanics, which is included under salaries, wages and benefits. It also excludes the amortization of heavy maintenance expenses, which we defer under the deferral method of accounting and amortize as a component of depreciation and amortization expense.

Distribution. Distribution expense includes all of our direct costs, including the cost of web support, our third-party call center, travel agent commissions and related GDS fees and credit card transaction fees, associated with the sale of our tickets and other products and services.

Special Charges (Credits). Special charges and credits include legal, advisory and other fees related to the Former Frontier Merger Agreement and the JetBlue Merger Agreement, the retention bonus programs, recognition of impairment charges related to the planned acceleration of the retirement of 29 of our A319 aircraft, the grant component of the PSP2 and PSP3 agreements with the Treasury, the CARES Act Employee Retention credit and amounts paid in connection with our involuntary employee separation programs.

Loss on Disposal of Assets. Loss on disposal of assets includes the net losses on the disposal of our fixed assets, the net losses or gains resulting from our aircraft and engine sale-leaseback transactions as well as the net losses or gains resulting from sale of our A319 airframes and engines.

Other Operating Expenses. Other operating expenses include airport operations expense and fees charged by third-party vendors for ground handling services and food and liquor supply service expenses, passenger re-accommodation expense, the cost of passenger liability and aircraft hull insurance, all other insurance policies except for employee related insurance, travel and training expenses for crews and ground personnel, professional fees, personal property taxes and all other administrative and operational overhead expenses. No individual item included in this category represented more than 5% of our total operating expenses.

Other (Income) Expense

Interest Expense. Interest expense in 2023 and 2022 primarily related to the financing of purchased aircraft, the interest and accretion related to our 8.00% senior secured notes, the interest and discount amortization related to our convertible notes and favorable mark to market adjustments of the derivative liability related to our convertible notes due 2026. Interest expense in 2021 primarily related to the financing of purchased aircraft as well as the interest related to our convertible notes and the interest and accretion related to our 8.00% senior secured notes.

Loss (gain) on Extinguishment of Debt. Gain on extinguishment of debt in 2023 was primarily related to the gain recognized due to the early extinguishment of certain of our outstanding fixed-rate term loans, and was partially offset by the write-offs of related deferred financing costs. Refer to "Notes to Consolidated Financial Statements —13. Debt and Other Obligations" for more information. We had no loss (gain) on extinguishment of debt in 2022. Loss on extinguishment of debt in

54

2021 primarily related to premiums paid to early extinguish a portion of our 8.00% senior secured notes and convertible notes due 2025. In addition, it includes the write-off of related deferred financing costs and original issuance discount.

Capitalized Interest. We capitalize the interest that is primarily attributable to the outstanding PDP balances as a percentage of the related debt on which interest is incurred. Capitalized interest represents interest cost incurred during the acquisition period of a long-term asset and is the amount which theoretically could have been avoided had we not paid PDPs for the related aircraft or engines. Capitalization of interest ceases when the asset is ready for service. Capitalized interest for 2023, 2022 and 2021 primarily relates to the interest incurred on long-term debt. In addition, during 2023, we capitalized interest related to the outstanding work in progress in connection to the building of our new headquarters.

Interest Income. For 2023, 2022 and 2021, interest income represents interest income earned on cash, cash equivalents and short-term investments as well as interest earned on income tax refunds.

Other Expense. Other expense primarily includes realized gains and losses related to foreign currency transactions.

Income Taxes

We account for income taxes using the asset and liability method. We record a valuation allowance to reduce the deferred tax assets reported if, based on the weight of the evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Deferred taxes are recorded based on differences between the financial statement basis and tax basis of assets and liabilities and available tax loss and credit carryforwards. In assessing the realizability of the deferred tax assets, we consider whether it is more likely than not that some or all of the deferred tax assets will be realized. In evaluating the ability to utilize our deferred tax assets, we consider all available evidence, both positive and negative, in determining future taxable income on a jurisdiction by jurisdiction basis.

Trends and Uncertainties Affecting Our Business

We believe our operating and business performance is driven by various factors affecting airlines and their markets, trends affecting the broader travel industry and trends affecting the specific markets and customer base that we target. The following key factors may affect our future performance.

Ability to Execute our Growth Strategy and Maintain or Grow Capacity. Over recent years, we have pursued a high-growth strategy, which we expect to continue. Execution of such a strategy requires us to effectively deploy new flying into our network, as new routes or increased frequency of existing routes develop. New flying may not perform as well as expected or may result in a competitive reaction. Moreover, our growth strategy depends on the timely delivery of aircraft and engines in accordance with the intended delivery schedule in accordance with the applicable agreement. Delivery delays and engine performance issues, as we have experienced in recent years, may cause us to scale back our growth. Our growth strategy also relies in part on our ability to obtain additional facilities in airports, some of which are constrained, as well as additional flight crew, maintenance, and other personnel.

In addition, we pursue a high-growth strategy that expands revenue and maintains lower cost due to economies of scale and lower initial expense for aircraft and labor. Execution of such a strategy depends on the ability to maintain efficient utilization of existing capacity and the timely delivery of new aircraft and engines. In addition, we previously experienced aircraft operational reliability issues and delivery delays particularly regarding our PW1100G engine on our A320neo aircraft. Beginning in the second half of 2020, the A320neo aircraft fleet reliability had stabilized and the PW1100G engine technical issues had improved. However, beginning in the second half of 2022, we began experiencing reliability issues with the PW1100G engines once again resulting in diminished service availability of aircraft. Supply chain delivery issues and limited capacity at MRO shops available to service PW1100G engines have resulted in extended turnaround time to perform the modifications required to improve the reliability of these engines. These impacts are expected to continue throughout 2024 and beyond, until supply chain and engine MRO shop capacity returns to required levels to support our growth. In addition, in July 2023, Pratt & Whitney announced that it had determined that a rare condition in the powdered metal used to manufacture certain engine parts will require accelerated inspection of the GTF fleet, which powers the A320neo aircraft. As of December 31, 2023, we have removed five engines from service, three of which are currently awaiting induction for inspection. Pratt & Whitney notified us that all GTF engines in its fleet, including the engines slotted for future aircraft deliveries, for a yet to be determined period, may be subject to the removal and inspection, or replacement, of the powdered metal high-pressure turbine and compressor discs. We currently estimate these engines will require removal and inspection in 2024, but continuing through 2026. Lower capacity resulting from manufacturer or supplier issues may lead to a significant adverse impact on our financial position and results of operations.

Supply chain delivery issues and limited capacity at MRO shops available to service PW1100G engines have resulted in extended turnaround time to perform the modifications required to improve the reliability of these engines. The new generation

55

aircraft provide fuel burn and other efficiencies, as compared to the older A320ceo aircraft, and the ability to serve additional markets with greater operating range. However, ongoing or expanded reliability and delivery issues could materially impact our operations, revenues, costs and net results.

In addition to the effects of Pratt & Whitney GTF engine issues on our operations, we have experienced an overall increase in volatility in seasonality as well as a decrease in year over year unit revenue and persistently high fuel prices, which have negatively affected revenue and costs. Should these trends continue into the future, our operating results may be negatively impacted. As a result, we have assessed the impact of such trends on our liquidity requirements and expect to have sufficient liquidity to meet our future cash needs for the next twelve months with cash and cash equivalents, cash flows from operations, the implementation of discretionary cost reduction strategies, and other financing arrangements. We also expect to receive compensation from Pratt & Whitney for the loss of utilization of the GTF engines.

Competition. The airline industry is highly competitive. The principal competitive factors in the airline industry are fare pricing, total price, flight schedules, aircraft type, passenger amenities, number of routes served from a city, customer service, safety record, reputation, code-sharing relationships, loyalty programs and redemption opportunities. Price competition occurs on a market-by-market basis through price discounts, changes in pricing structures, fare matching, target promotions and loyalty program initiatives. Airlines typically use discount fares and other promotions to stimulate traffic during normally slower travel periods in efforts to maximize unit revenue. The prevalence of discount fares can be particularly acute when a competitor has excess capacity that it is under financial pressure to sell tickets.

Moreover, the network carriers have developed a fare-class pricing approach, in which a portion of available seats may be sold at or near ULCC prices, but without most product features available to their passengers paying at higher fare levels on the same flight. Broad fare discounting may have the effect of diluting the profitability of revenues of high-cost carriers but the fare-class approach may allow network carriers to continue offering a competitive price to ULCCs on some flights or routes, while maintaining higher pricing to their traditional constituencies of corporate and less price-sensitive travelers. Refer to “Risk Factors—Risks Related to Our Industry—We operate in an extremely competitive industry."

Seasonality and Volatility. Our results of operations for any interim period are not necessarily indicative of those for the entire year because the air transportation business is subject to significant seasonal fluctuations. We generally expect demand to be greater in the second and third quarters compared to the rest of the year. The air transportation business is also volatile and highly affected by economic cycles and trends. Consumer confidence and discretionary spending, fear of terrorism or war, weakening economic conditions, fare initiatives, fluctuations in fuel prices, labor actions, changes in governmental regulations on taxes and fees, weather, outbreaks of pandemic or contagious diseases and other factors have resulted in significant fluctuations in revenues and results of operations in the past. We believe demand for business travel historically has been more sensitive to economic pressures than demand for low-price travel. Finally, a significant portion of our operations are concentrated in markets such as South Florida, the Caribbean, Latin America and the Northeast and northern Midwest regions of the United States, which are particularly vulnerable to weather, airport traffic constraints and other delays.

Aircraft Fuel. Fuel costs represents one of our largest operating expenses, as it does for most airlines. Fuel costs have been subject to wide price fluctuations in recent years. Fuel availability and pricing are also subject to refining capacity, periods of market surplus, and shortage and demand for heating oil, gasoline and other petroleum products, as well as meteorological, economic and political factors and events occurring throughout the world, which we can neither control nor accurately predict. We source a significant portion of our fuel from refining resources located in the southeast United States, particularly facilities adjacent to the Gulf of Mexico. Gulf Coast fuel is subject to volatility and supply disruptions, particularly in hurricane season when refinery shutdowns have occurred, or when the threat of weather-related disruptions has caused Gulf Coast fuel prices to spike above other regional sources. Our fuel hedging practices are dependent upon many factors, including our assessment of market conditions for fuel, our access to the capital necessary to support margin requirements, the pricing of hedges and other derivative products in the market, our overall appetite for risk and applicable regulatory policies. As of December 31, 2023, we had no outstanding jet fuel derivatives and we have not engaged in fuel derivative activity since 2015. The cost and future availability of jet fuel cannot be predicted with any degree of certainty.

Labor. The airline industry is heavily unionized. The wages, benefits and work rules of unionized airline industry employees are determined by CBAs. Relations between air carriers and labor unions in the United States are governed by the RLA. Under the RLA, CBAs generally contain “amendable dates” rather than expiration dates, subject to standard early opener provisions, and the RLA requires that a carrier maintain the existing terms and conditions of employment following the amendable date through a multi-stage and usually lengthy series of bargaining processes overseen by the NMB. This process continues until either the parties have reached agreement on a new CBA, or the parties have been released to “self-help” by the NMB. In most circumstances, the RLA prohibits strikes; however, after release by the NMB, carriers and unions are free to engage in self-help measures such as strikes and lockouts.

56

We have six union-represented employee groups comprising approximately 85% of our employees at December 31, 2023. Our pilots are represented by the Air Line Pilots Association, International, or ALPA, our flight attendants are represented by the Association of Flight Attendants, or AFA-CWA, our dispatchers are represented by the Professional Airline Flight Control Association, or PAFCA, our ramp service agents are represented by the International Association of Machinists and Aerospace Workers, or IAMAW and our passenger service agents are represented by the Transport Workers Union, or TWU. In addition, our aircraft maintenance technicians are represented by the Aircraft Mechanics Fraternal Association, or AMFA. The related collective bargaining agreement is currently under negotiation. Conflicts between airlines and their unions can lead to work slowdowns or stoppages.

During the fourth quarter of 2022, we reached an agreement with ALPA for a new two-year agreement, which was ratified by ALPA members on January 10, 2023. The ratified agreement includes increased pay rates and other enhanced benefits.

In February 2021, we entered into a Letter of Agreement with the AFA-CWA to change the amendable date of the collective bargaining agreement from May 4, 2021 to September 1, 2021. All other terms of the collective bargaining agreement remained the same. In June 2021, the AFA-CWA notified us, as required by the RLA, that it intended to submit proposed changes to the collective bargaining agreement covering our flight attendants. We commenced negotiations with the AFA-CWA on September 27, 2021. In February 2023, we reached an agreement with our flight attendants which was ratified by the flight attendants on April 13, 2023 and becomes amendable in January 2026. The ratified agreement includes increased pay rates and other enhanced benefits.

Our dispatchers are represented by the PAFCA. In October 2018, we reached a tentative agreement with PAFCA for a new five-year agreement, which was ratified by the PAFCA members in October 2018. In May 2023, PAFCA provided notice that it intends to amend its Collective Bargaining Agreement with our dispatchers. The parties began negotiating changes to the CBA on July 12, 2023. As of December 31, 2023, we continued to negotiate with PAFCA.

Our ramp service agents are represented by IAMAW. Representation only applies to our Fort Lauderdale station where we have direct employees in the ramp service agent classification. In February 2020, the IAMAW notified us, as required by the RLA, that it intended to submit proposed changes to the collective bargaining agreement covering our ramp service agents which became amendable in June 2020. On September 28, 2021, we filed an “Application for Mediation Services” with the NMB. We were able to reach a tentative agreement with the IAMAW with the assistance of the NMB on October 16, 2021. Our ramp service agents ratified the five-year agreement in November 2021.

In June 2018, our passenger service agents voted to be represented by the TWU, but the representation only applies to our Fort Lauderdale station where we have direct employees in the passenger service classification. We began meeting with the TWU in late October 2018 to negotiate an initial collective bargaining agreement. During February 2022, we reached a tentative agreement with the TWU. Our passenger service agents ratified the five-year agreement on February 21, 2022.

In August 2022, our AMTs voted to be represented by AMFA as their collective bargaining agent. In November 2022, AMFA notified us of its intent to negotiate a CBA and began negotiations. In October 2023, AMFA filed for mediation with the NMB, and we are currently waiting for mediation dates from the NMB to continue negotiating with AMFA.

We believe our CBAs provide us with competitive labor costs compared to other U.S.-based low-cost carriers. If we are unable to reach agreement with any of our unionized work groups in current or future negotiations regarding the terms of their CBAs, we may be subject to work interruptions or stoppages, such as the strike by our pilots in June 2010. A strike or other significant labor dispute with our unionized employees is likely to adversely affect our ability to conduct business. Any agreement we do reach could increase our labor and related expenses.

In 2010, the Patient Protection and Affordable Care Act was passed into law. This law may be repealed in its entirety or certain aspects may be changed or replaced. If the law is repealed or modified or if new legislation is passed, such action could potentially increase our operating costs, with healthcare costs increasing at a higher rate than our employee headcount.

Maintenance Expense. Maintenance expense grew through 2023 and 2022 mainly as a result of increased aircraft utilization compared to the prior year, a growing fleet and the gradual increase of required maintenance for the older aircraft in our fleet. As our fleet ages, we expect that maintenance costs will increase in absolute terms. The amount of total maintenance costs and related amortization of heavy maintenance (included in depreciation and amortization expense) is subject to many variables such as future utilization rates, average stage length, the interval between heavy maintenance events, the size and makeup of the fleet in future periods and the level of unscheduled maintenance events and their actual costs. Accordingly, we cannot reliably quantify future maintenance expenses for any significant period of time.

57

    As a result of a majority of our fleet being acquired over a relatively short period of time, heavy maintenance scheduled on certain aircraft will overlap, meaning we will incur our most expensive scheduled maintenance obligations on certain aircraft at roughly the same time. These more significant maintenance activities will result in out-of-service periods during which our aircraft will be dedicated to maintenance activities and unavailable to fly revenue service. When accounting for maintenance expense under the deferral method, heavy maintenance is amortized over the shorter of either the remaining lease term or the next estimated heavy maintenance event. As a result, deferred maintenance events occurring closer to the end of the lease term will generally have shorter amortization periods than those occurring earlier in the lease term. This will create higher depreciation and amortization expense specific to any aircraft related to heavy maintenance during the final years of the lease as compared to earlier periods.

Critical Accounting Policies and Estimates

The following discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these consolidated financial statements requires us to make estimates and judgments that affect the reported amount of assets and liabilities, revenues and expenses and related disclosures of contingent assets and liabilities at the date of our consolidated financial statements. For a detailed discussion of our significant accounting policies, refer to “Notes to Consolidated Financial Statements—1. Summary of Significant Accounting Policies.”

Critical accounting policies are defined as those policies that reflect significant judgments or estimates about matters both inherently uncertain and material to our financial condition or results of operations.

Leased Aircraft Return Costs. Our aircraft lease agreements often contain provisions that require us to return aircraft airframes and engines to the lessor in a certain condition or pay an amount to the lessor based on the airframe and engine's actual return condition. Lease return costs include all costs that would be incurred at the return of the aircraft, including costs incurred to repair the airframe and engines to the required condition as stipulated by the lease. Lease return costs are recognized beginning when it is probable that such costs will be incurred and they can be estimated. When costs become both probable and estimable, they are accrued as a component of supplemental rent, through the remaining lease term. We expensed $14.0 million and $16.5 million of supplemental rent recorded within aircraft rent during 2023 and 2022, respectively. Supplemental rent, recorded within aircraft rent expense, is primarily made up of probable and estimable return condition obligations and lease return costs adjustments for aircraft and engines purchased off lease.

When determining the need to accrue lease return costs, there are various factors which need to be considered such as the contractual terms of the lease agreement, current condition of the aircraft, the age of the aircraft at lease expiration, and projected number of hours run on the engine at the time of return, among others. In addition, typically near the lease return date, the lessors may allow reserves to be applied as return condition consideration or pass on certain return provisions if they do not align with their current plans to remarket the aircraft. As a result of the different factors listed above, management assesses the need to accrue lease return costs periodically throughout the year or whenever facts and circumstances warrant an assessment. Lease return costs will generally be estimable closer to the end of the lease term but may be estimable earlier in the lease term depending on the contractual terms of the lease agreement and the timing of maintenance events for a particular aircraft. We expect lease return costs will increase as individual aircraft lease agreements approach their respective termination dates and we begin to accrue the estimated cost of return conditions for the corresponding aircraft. Upon a termination of the lease due to a breach by us, we would be liable for standard contractual damages, possibly including damages suffered by the lessor in connection with remarketing the aircraft or while the aircraft is not leased to another party.

Results of Operations

In 2023, we generated operating revenues of $5,362.5 million and had an operating loss of $495.8 million resulting in a negative operating margin of 9.2% and a net loss of $447.5 million. In 2022, we generated operating revenues of $5,068.4 million and had an operating loss of $598.9 million, resulting in a negative operating margin of 11.8% and a net loss of $554.2 million. The increase in operating revenues, year over year, is primarily due to an increase in traffic of 13.7%, year over year, partially offset by a decrease in average yield of 7.0%, year over year. Increased salaries, wages and benefits expense and aircraft rent expense compared to the prior year period, primarily contributed to higher operating expenses. In addition, increased operations resulted in higher operating expenses across the board.

As of December 31, 2023, our cash and cash equivalents was $865.2 million, a decrease of $481.1 million compared to the prior year. Cash and cash equivalents is generally driven by cash from our operating activities as well as capital from debt and equity financings, offset by cash used to fund PDPs and capital expenditures and principal payments related to our long-

58

term debt. In addition to cash and cash equivalents, as of December 31, 2023, we had $112.5 million in short-term investment securities.

Operating revenues increased by $294.1 million, or 5.8%, to $5,362.5 million in 2023 compared to 2022, primarily due to an increase in traffic of 13.7%, partially offset by a decrease in average yield of 7.0%, year over year.

TRASM for 2023 was 9.63 cents, a decrease of 7.8% compared to 2022. This decrease was primarily a result of a 7.0% decrease in operating yield, year over year.

Total revenue per passenger flight segment decreased 7.7% from $131.78 in 2022 to $121.58 in 2023. The decrease in total revenue per passenger flight segment was primarily due to a decrease of 7.0% in average yield, year over year. Fare revenue per passenger flight segment decreased 17.0%, as compared to the prior year period, while non-ticket revenue per passenger flight segment increased slightly by 0.9%, as compared to the prior year period.

Operating expenses increased by $190.9 million, or 3.4%, in 2023 primarily due to an increase in salaries, wages and benefits expense, aircraft rent expense, other operating expense and landing fees and other rents expense, compared to the prior year period. In addition, we had an increase in operations, as reflected by a 13.7% increase in traffic and a 14.6% increase in capacity, as a result of increased travel demand as compared to the prior year. These increases were offset by decreases in special charges, period over period, as well as a decrease of 15.8% in fuel price per gallon, of which contributed to a $108.8 million decrease in aircraft fuel expense, period over period.

Our Adjusted CASM ex-fuel for the twelve months ended December 31, 2023 was 7.06 cents, as compared to 6.73 cents for the twelve months ended December 31, 2022. The increase on a per-ASM basis was primarily due to increases in salaries, wages and benefits expense and aircraft rent expense, partially offset by a decrease in depreciation and amortization expense.

Aircraft fuel expenses includes both into-plane expense (as defined below) and realized and unrealized net gains or losses from fuel derivatives, if any. Into-plane fuel expense is defined as the price that we generally pay at the airport, including taxes and fees. Into-plane fuel prices are affected by the global oil market, refining costs, transportation taxes and fees, which can vary by region in the United States and other countries where we operate. Into-plane fuel expense approximates cash paid to the supplier and does not reflect the effect of any fuel derivatives. We had no activity related to fuel derivative instruments during 2023 and 2022.

Aircraft fuel expense decreased by 5.6% from $1,930.0 million in 2022 to $1,821.2 million in 2023. This decrease was due to a 15.8% decrease in fuel price per gallon, partially offset by a 12.2% increase in fuel gallons consumed.

The elements of the changes in aircraft fuel expense are illustrated in the following table:

	Twelve Months Ended December 31,
	2023		2022
	(in thousands, except per-gallon amounts)				Percent Change
Fuel gallons consumed	591,796		527,290		12.2	%
Into-plane fuel cost per gallon	$	3.08	$	3.66	(15.8)	%
Aircraft fuel expense (per consolidated statements of operations)	$	1,821,165	$	1,929,969	(5.6)	%

Gulf Coast Jet indexed fuel is the basis for a substantial majority of our fuel consumption and is impacted by both the price of crude oil as well as increases or decreases in refining margins associated with the conversion of crude oil to jet fuel.

Salaries, wages and benefits expense in 2023 increased by $365.6 million, or 29.2%, compared to 2022. This increase on a dollar and per-ASM basis was primarily driven by higher salaries, vacation-time expense, 401(k) expense and crew overtime. These increases were mainly driven by contractual pay rate increases related to the collective bargaining agreements with our pilots and flight attendants ratified in January 2023 and April 2023, respectively. In addition, these increases were driven by a 16.4% increase in our pilot and flight attendant workforce, period over period, as well as an increase in operations as compared to the prior year period. The increase in salaries, wages and benefits expense is also due to an increase in health insurance expense, mainly driven by higher volume of claims.

Landing fees and other rents for 2023 increased by $61.0 million, or 17.6%, compared to 2022. On a dollar basis, landing fees and other rents expense primarily increased as a result of an increase in facility rent, landing fees and station baggage rent, driven by increased operations, higher rent rates and the addition of new stations as well as new gates at our existing stations,

61

period over period. Gate charges, landing fees, as well as a portion of facility rent and station baggage rent are variable in nature and vary based on factors such as the number of departures and passengers. As compared to the prior year period, departures increased by 14.1% and passenger flight segments increased by 14.7%. On a per-ASM basis, landing fees and other rents remained relatively consistent, period over period.

Aircraft rent expense in 2023 increased by $98.8 million, or 35.0%, compared to 2022. This increase in aircraft rent expense was primarily due to an increase in the number of aircraft financed under operating leases throughout the current period, as compared to the prior year period. The increase on a dollar and per-ASM basis in aircraft rent expense was primarily due to an increase in the number of aircraft financed under operating leases throughout the current period, as compared to the prior year period. Since 2022, we have recorded 29 new operating leases related to new and previously owned aircraft.

Depreciation and amortization increased by $7.8 million, or 2.5%, compared to the prior year. The increase in depreciation and amortization expense on a dollar basis was primarily driven by an increase in spare engines and computer software, as well as amortization of new engine overhauls capitalized in the period. Since 2022, we have taken delivery of four spare engines purchased with cash. This increase was partially offset by a decrease in depreciation and amortization expense in the current period, as a result of the impact of the impairment of 29 of our A319 aircraft associated with the decision to accelerate their retirement during the fourth quarter of 2022 and the sale of 12 A319 airframes and 20 A319 engines during the twelve months ended December 31, 2023. On a per-ASM basis, depreciation and amortization expense decreased due to a change in the composition of our aircraft fleet between purchased aircraft (for which depreciation expense is recorded under depreciation and amortization) and leased aircraft (for which rent expense is recorded under aircraft rent). Since the prior year period, we have taken delivery of 23 new leased aircraft, which increased capacity but had no effect on depreciation expense.

We account for heavy maintenance under the deferral method. Under the deferral method, the cost of heavy maintenance is capitalized and amortized as a component of depreciation and amortization expense in the consolidated statements of operations until the earlier of the next heavy maintenance event or end of the lease term. The amortization of heavy maintenance costs was $79.8 million and $96.7 million for the year ended December 31, 2023 and 2022, respectively. The decrease in amortization of heavy maintenance costs, period over period, was primarily related to the impact of the impairment of 29 of our A319 aircraft, including the related net capitalized maintenance, associated with the decision to accelerate their retirement during the fourth quarter of 2022. However, as our fleet continues to age, we expect that the amount of deferred heavy maintenance events will increase and will result in an increase in the amortization of those costs. If the amortization of heavy maintenance events were recorded within maintenance, materials and repairs expense in the consolidated statements of operations, our maintenance, materials and repairs expense would have been $303.1 million and $284.5 million for the year ended December 31, 2023 and 2022, respectively.

Maintenance, materials and repairs expense increased by $35.5 million, or 18.9%, in 2023, as compared to 2022. The increase on a dollar basis was mainly due to a higher volume of aircraft and rotable maintenance events as a result of a 14.1% increase in departures in the current period as compared to the prior year period. On a per-ASM basis, maintenance, materials and repairs expense remained relatively stable since the prior year period.

Distribution expense increased by $13.3 million, or 7.5%, in 2023, compared to 2022. The increase on a dollar was primarily due to increased sales volume as well as an increase in credit card fee rates, which impacts our variable distribution costs such as credit card fees. On a per-ASM basis, distribution costs decreased primarily due to lower average fare resulting in a decrease in credit card fees, year over year, and also due to a decrease in sales from third-party travel agents.

Special charges (credits) for the year ended 2023 consisted of $50.0 million in legal, advisory and other fees related to the Merger Agreement with JetBlue, as well as $19.5 million related to the retention award program in connection with the Merger Agreement with JetBlue. Special charges (credits) for the year ended 2022 consisted of $333.7 million in impairment charges related to the purchase agreement to sell 29 of our A319 aircraft, $47.2 million in legal, advisory and other fees related to the Former Frontier Merger Agreement, JetBlue's unsolicited proposal to acquire all of our outstanding shares in an all-cash transaction and the JetBlue Merger Agreement as well as $39.3 million related to our retention award programs. For additional information, refer to "Notes to Consolidated Financial Statements— 4. Special Charges and Credits."

Loss on disposal of assets totaled $34.0 million for the year ended 2023. This loss on disposal of assets primarily consisted of a $32.1 million loss related to the 6 aircraft sale-leaseback transactions (on existing aircraft), a net loss of $1.6 million related to the sale of 12 A319 airframes and 20 A319 engines as well as a $3.3 million loss primarily related to the disposal of obsolete assets, partially offset by a net gain of $3.0 million related to 10 aircraft sale-leaseback transactions related to new aircraft deliveries completed during the twelve months ended December 31, 2023. Loss on disposal of assets totaled $46.6 million for the year ended 2022. This loss on disposal of assets primarily consisted of $38.5 million related to the loss on 16 aircraft sale-leaseback transactions completed during 2022 and $6.6 million related to the impairment of 1 spare engine during the first quarter of 2022 which was damaged beyond economic repair.

62

Other operating expenses in 2023 increased by $81.0 million, or 11.4%, compared to 2022. The increase in other operating expenses on a dollar basis was primarily due to an increase in ground handling expense, software maintenance, travel and lodging expense and other airport services expense, period over period, primarily as a result of an increase in operations. As compared to the prior year period, departures increased by 14.1%, and we had 14.7% more passenger flight segments, which drove increases in variable other operating expenses. Additionally, we recorded a litigation loss contingency of $6.0 million in the second quarter of 2023. These increases were offset by a decrease in passenger reaccommodation expense, period over period, related to a number of adverse weather events and increases in air traffic control programs and restrictions, which led to a significant number of flight delays and cancellations during the first half of 2022. In addition, these increases were partially offset by engine credits earned in the current period. On a per-ASM basis, other operating expenses decreased primarily due to a decrease in passenger reaccommodation expense compared to the prior year period as well as engine credits earned in the period, partially offset by an increase in software maintenance.

Other (Income) Expense

Other (income) expense, net decreased from $101.8 million in 2022 to $62.8 million in 2023, was primarily driven by an increase in interest income of $41.6 million as well as an increase in gain on extinguishment of debt of $15.4 million, recognized from favorable interest rate swap provisions contained in certain debt agreements extinguished during the fourth quarter of 2023, and partially offset by the write-off of related deferred financing costs. The increase in interest income was primarily due to an increase in interest rates as compared to the prior year period. These increases in interest income and gain on extinguishment of debt were partially offset by an increase in interest expense of $29.3 million, which was primarily due to the increase in interest and accretion, year over year, as a result of the additional $600.0 million 8.00% senior secured notes incurred during the fourth quarter 2022.

Income Taxes

In 2023, our effective tax rate was 19.9% compared to 20.9% in 2022. While we expect our tax rate to be fairly consistent in the near term, it will tend to vary depending on recurring items such as the amount of income we earn in each state and the state tax rate applicable to such income. Discrete items particular to a given year may also affect our effective tax rates.

Liquidity and Capital Resources

Our primary sources of liquidity generally include cash on hand, cash provided by operations and capital from debt and equity financing. Primary uses of liquidity are for working capital needs, capital expenditures, aircraft and engine pre-delivery deposit payments ("PDPs") and debt and lease obligations. We expect to meet our cash needs for the next twelve months with cash and cash equivalents, cash flows from operations, the implementation of discretionary cost reduction strategies and other financing arrangements. As of December 31, 2023, we had $1,277.7 million in liquid assets comprised of unrestricted cash and cash equivalents, short-term investment securities and funds available under our revolving credit facility. From time to time and subject to market conditions and any applicable contractual requirements, we may refinance portions of our debt, including our 2025 maturities, which, at current interest rates and market conditions, may negatively impact our interest expense or result in higher dilution. In addition, from time to time, we may decide to repurchase or otherwise retire portions of our existing indebtedness through transactions in the open market, privately negotiated transactions, tender offers, exchange offers or otherwise, or we may redeem or prepay portions of our existing indebtedness pursuant to its terms. Any such action will depend on market conditions and any applicable contractual requirements.

63

As of December 31, 2023, we had $25.1 million recorded within current maturities of long-term debt and finance leases on our consolidated balance sheets related to our convertible notes due 2025. As of December 31, 2023, the convertible notes due 2025 may be converted by noteholders through March 31, 2024. During the first quarter of 2023, $0.3 million of our convertible notes due 2025 were converted to 27,204 shares of our voting common stock. Refer to “Notes to Consolidated Financial Statements—13. Debt and Other Obligations,” for additional information.

As of December 31, 2023, we had $472.6 million, net of the related unamortized debt discount of $27.4 million, recorded within long-term debt, net and finance leases, less current maturities on our consolidated balance sheets related to our convertible notes due 2026. As of December 31, 2023, the convertible notes due 2026 did not qualify for conversion by noteholders through March 31, 2024. Refer to “Notes to Consolidated Financial Statements —13. Debt and Other Obligations” for additional information.

Currently, one of our largest capital expenditure needs is funding the acquisition costs of our aircraft. Aircraft are acquired through debt financing, cash purchases, direct leases or sale-leaseback transactions. During the twelve months ended December 31, 2023, we took delivery of 13 aircraft under direct operating leases, 10 aircraft under sale-leaseback transactions and 4 spare engines purchased with cash. During the twelve months ended December 31, 2023, we made $730.1 million in debt payments (principal, interest and fees) on our outstanding aircraft debt obligations.

Under our purchase agreements for aircraft and engines, we are required to pay PDPs relating to future deliveries at various times prior to each delivery date. During 2023, we paid $23.2 million in PDPs, net of refunds, and $21.9 million of capitalized interest for future deliveries of aircraft and spare engines. As of December 31, 2023, we had $480.7 million of pre-delivery deposits on flight equipment, including capitalized interest, on our consolidated balance sheet.

As of December 31, 2023, we had secured financing for 22 aircraft to be leased directly from third-party lessors, scheduled for delivery through 2025, and 18 aircraft which will be financed through sale-leaseback transactions, scheduled for delivery through 2025. As of December 31, 2023, we did not have financing commitments in place for the remaining 81 Airbus firm aircraft orders, scheduled for delivery through 2029. However, we have signed a financing letter of agreement with Airbus which provides backstop financing for a majority of the aircraft included in the A320 NEO Family Purchase Agreement. The agreement provides a standby credit facility in the form of senior secured mortgage debt financing. Future aircraft deliveries may be paid in cash, leased or otherwise financed based on market conditions, our prevailing level of liquidity, and capital market availability.

As of December 31, 2023, we were compliant with our credit card processing agreements, and not subject to any credit card holdbacks. The maximum potential exposure to cash holdbacks by our credit card processors, based upon advance ticket sales and Spirit Saver$ Club® memberships, as of December 31, 2023 and December 31, 2022, was $408.3 million and $468.5 million, respectively.

During the fourth quarter of 2023, we early extinguished $323.3 million of outstanding fixed-rate term loans on 16 of our aircraft. In connection with this debt extinguishment, we received $17.8 million related to favorable interest rate swap provisions contained in the debt agreements associated with these fixed-rate term loans. This amount was recorded within loss (gain) on extinguishment of debt on our consolidated statement of operations for the twelve months ended December 31, 2023. In addition, during December 2023, we completed 20 sale-leaseback transactions (on aircraft we previously owned) of which, 6 resulted in operating leases and 14 would have been deemed finance leases resulting in failed sale-leaseback transactions. Refer to “Notes to Consolidated Financial Statements — Note 14”, Leases for additional information on the 20 sale-leaseback transactions.

Net Cash Flows Provided (Used) By Operating Activities. Operating activities in 2023 used $246.7 million in cash compared to $89.0 million used in 2022. Cash used by operating activities during 2023 was primarily related to the net loss in the period as well as an increase in deferred heavy maintenance and a decrease in deferred income tax benefit in the period. The cash used in the period was partially offset by higher non-cash expense of depreciation and amortization, as well as increases in other liabilities and air traffic liability.

Operating activities in 2022 used $89.0 million in cash compared to $208.9 million provided in 2021. Cash used by operating activities during 2022 was primarily related to the net loss in the period as well as an increase in deferred heavy maintenance and a decrease in deferred income tax benefit in the period. The cash used in the period was partially offset by higher non-cash expense of fixed asset impairment and depreciation and amortization, as well as increases in other liabilities and air traffic liability.

64

Net Cash Flows Used In Investing Activities. During 2023, investing activities used $36.5 million, compared to $265.4 million used in 2022. The cash used was mainly driven by the purchase of property, plant and equipment, partially offset by proceeds from the sale of property, plant and equipment.

During 2022, investing activities used $265.4 million, compared to $352.4 million used in 2021. The cash used was mainly driven by the purchase of property, plant and equipment.

Net Cash Provided (Used) By Financing Activities. During 2023, financing activities used $198.0 million. Cash used was mainly driven by cash payments on debt obligations and payments to extinguish debt early, partially offset by the proceeds of the issuance of long-term debt. Refer to "Notes to Consolidated Financial Statements —13. Debt and Other Obligations" for additional information.

During 2022, financing activities provided $391.3 million. During the twelve months ended December 31, 2022, we received $591.0 million, net, related to the issuance of the 8.00% Additional Notes due 2025, partially offset by $193.0 million in payments on debt obligations. Refer to "Notes to Consolidated Financial Statements —13. Debt and Other Obligations" for additional information.

Commitments and Contractual Obligations

Our contractual purchase commitments consist primarily of aircraft and engine acquisitions through manufacturers and aircraft leasing companies. As of December 31, 2023, our firm aircraft orders consisted of 99 A320 family aircraft with Airbus, including A320neos and A321neos, with deliveries expected through 2029. On July 31, 2023, we entered into Amendment No. 6 (the “Amendment”) to the Airbus Purchase Agreement. The Amendment converts the A319neo aircraft to be delivered under the Airbus Purchase Agreement to A321neo aircraft. The Amendment also (i) defers certain A320neo aircraft deliveries from 2024 to 2025 and later years, (ii) extends delivery dates for certain A320neo and A321neo aircraft deliveries from 2025-2027 to 2025-2029 and (iii) adjusts the timing of option aircraft delivery dates from 2026-2028 to 2027-2029. In addition, the Amendment creates a more equal distribution of aircraft deliveries and option rights across the delivery periods. As of December 31, 2023, we had secured financing for 18 aircraft, scheduled for delivery from Airbus from through 2025, which will be financed through sale-leaseback transactions. The contractual purchase amounts for these aircraft from Airbus are included within the flight equipment purchase obligations in the table below. We did not have financing commitments in place for the remaining 81 Airbus aircraft currently on firm order, which are scheduled for delivery through 2029. However, we have signed a financing letter of agreement with Airbus which provides backstop financing for a majority of the aircraft included in the A320 NEO Family Purchase Agreement. The agreement provides a standby credit facility in the form of senior secured mortgage debt financing.

During the third quarter of 2021, we entered into an Engine Purchase Support Agreement which requires us to purchase a certain number of spare engines in order to maintain a contractual ratio of spare engines to aircraft in the fleet. As of December 31, 2023, we are committed to purchase 19 PW1100G-JM spare engines, with deliveries through 2029.

During the third quarter of 2019, the United States announced its decision to levy tariffs on certain imports from the European Union, including commercial aircraft and related parts. These tariffs include aircraft and other parts that we are already contractually obligated to purchase including those reflected below. In June 2021, the United States Trade Representative announced that the United States and European Union had agreed to suspend reciprocal tariffs on large civilian aircraft for five years, pending discussions to resolve their trade dispute. For further discussion on this topic, please refer to "Risk Factors - Risks Related to Our Business - Any tariffs imposed on commercial aircraft and related parts imported from outside the United States may have a material adverse effect on our fleet, business, financial condition and our results of operations."

65

In addition to the aircraft purchase agreement, as of December 31, 2023, we had secured financing for 22 aircraft to be leased directly from third-party lessors, scheduled for delivery through 2025. Aircraft rent commitments for future aircraft deliveries to be financed under these direct leases from third-party lessors and sale-leaseback transactions are expected to be approximately $72.4 million in 2024, $167.8 million in 2025, $183.3 million in 2026, $183.3 million in 2027, $183.3 million in 2028 and $1,409.3 million in 2029 and beyond. These future commitments are not included in the table below.

We have significant obligations for aircraft and spare engines as we had 132 leased aircraft, of which 117 aircraft were financed under operating leases and 15 aircraft would have been deemed finance leases resulting in failed sale-leaseback transactions, and 6 spare engines were financed under operating leases. Aircraft rent payments were $389.6 million and $286.0 million for 2023 and 2022, respectively, for aircraft which were financed under operating leases. Aircraft rent payments were $6.5 million and $4.3 million for 2023 and 2022, respectively, for aircraft which would have been deemed finance leases resulting in failed sale-leaseback transactions. Refer to “Notes to Consolidated Financial Statements—13. Debt and Other Obligations” and “Notes to Consolidated Financial Statements—14. Leases" for additional information.

ITEM 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market Risk-Sensitive Instruments and Positions

We are subject to certain market risks, including commodity prices (specifically aircraft fuel) and interest rates. We purchase the majority of our jet fuel at prevailing market prices and seek to manage market risk through execution of our hedging strategy and other means. However, we do not currently hold any derivative financial instruments. We have market-sensitive instruments in the form of fixed-rate debt instruments. The adverse effects of changes in these markets could pose a potential loss as discussed below. The sensitivity analysis provided below does not consider the effects that such adverse changes may have on overall economic activity, nor does it consider additional actions we may take to mitigate our exposure to such changes. Actual results may differ.

Aircraft Fuel. Our results of operations can vary materially due to changes in the price and availability of aircraft fuel. Aircraft fuel expense for the years ended December 31, 2023, represented approximately 31.1% of our operating expenses. Volatility in aircraft fuel prices or a shortage of supply could have a material adverse effect on our operations and operating results. We source a significant portion of our fuel from refining resources located in the southeast United States, particularly facilities adjacent to the Gulf of Mexico. Gulf Coast fuel is subject to volatility and supply disruptions, particularly during hurricane season when refinery shutdowns have occurred, or when the threat of weather-related disruptions has caused Gulf Coast fuel prices to spike above other regional sources. Gulf Coast Jet indexed fuel is the basis for a substantial majority of our fuel consumption. Based on our annual fuel consumption, a hypothetical 10% increase in the average price per gallon of aircraft fuel would have increased into-plane aircraft fuel cost for 2023 by $182.1 million.

Interest Rates. We have market risk associated with our short-term investment securities, which had a fair market value of $112.5 million as of December 31, 2023.

Fixed-Rate Debt. As of December 31, 2023, we had $1,667.7 million outstanding in fixed-rate debt related to 41 Airbus A320 aircraft and 30 Airbus A321 aircraft, which had a fair value of $1,611.1 million. In addition, as of December 31, 2023, we had $1,110.0 million and $136.3 million outstanding in fixed-rate debt related to our 8.00% senior secured notes and our unsecured term loans, respectively, which had fair values of $1,121.9 million and $128.3 million. As of December 31, 2023, we also had $525.1 million outstanding in convertible debt which had a fair value of $392.2 million.

Variable-Rate Debt. As of December 31, 2023, we did not have any outstanding variable-rate long term debt.

Notes to Consolidated Financial Statements

1.Summary of Significant Accounting Policies

Basis of Presentation

The accompanying consolidated financial statements include the accounts of Spirit Airlines, Inc. ("Spirit") and its consolidated subsidiaries (the "Company"). Spirit is an ultra low-cost, low-fare airline that provides affordable travel opportunities principally throughout the domestic United States, the Caribbean and Latin America and is headquartered in Miramar, Florida. Spirit manages operations on a system-wide basis due to the interdependence of its route structure in the various markets served. As only one service is offered (i.e., air transportation), management has concluded there is only one reportable segment.

Use of Estimates

The preparation of financial statements in accordance with generally accepted accounting principles in the United States of America requires the Company's management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The Company's estimates and assumptions are based on historical experience and changes in the business environment. However, actual results may differ from estimates under different conditions, sometimes materially.

Cash and Cash Equivalents

The Company considers all highly liquid investments with maturities of less than three months at the date of acquisition to be cash equivalents. Investments included in this category primarily consist of cash and money market funds. Cash and cash equivalents are stated at cost, which approximates fair value.

Restricted Cash

The Company's restricted cash is comprised of cash held in account subject to account control agreements to be used for the payment of interest and fees on the Company's 8.00% senior secured notes and cash pledged as collateral against the Company's secured letters of credit.

Short-term Investment Securities

The Company's short-term investment securities are classified as available-for-sale and generally consist of U.S. Treasury and U.S. government agency securities with contractual maturities of twelve months or less. These securities are stated at fair value within current assets on the Company's consolidated balance sheet. For all short-term investments, at each reset period or upon reinvestment, the Company accounts for the transaction as proceeds from the maturity of short-term investment securities for the security relinquished, and purchase of short-term investment securities for the security purchased, in the Company's consolidated statements of cash flows. Realized gains and losses on sales of investments, if any, are reflected in non-operating other (income) expense in the consolidated statements of operations. Unrealized gains and losses on investment securities are reflected as a component of accumulated other comprehensive income.

Accounts Receivable

Accounts receivable primarily consist of amounts due from credit card processors associated with the sales of tickets, amounts due from the Internal Revenue Service related to federal excise fuel tax and amounts expected to be received related to the CARES Employee Retention credit. The Company records an allowance for amounts not expected to be collected. The Company estimates the allowance based on historical write-offs and aging trends as well as an estimate of the expected lifetime credit losses. The allowance for doubtful accounts was immaterial as of December 31, 2023 and 2022.

In addition, the provision for doubtful accounts and write-offs for 2023, 2022 and 2021 were each immaterial.

Income Tax Receivable

Income tax receivable consists of amounts due from tax authorities for recovery of income taxes paid in prior periods.

Property and Equipment

Property and equipment is stated at cost, less accumulated depreciation and amortization. Depreciation of operating property and equipment is computed using the straight-line method applied to each unit of property. Residual values for new aircraft, new engines, major spare rotable parts, avionics and assemblies are generally estimated to be 10%. Property under

78

Notes to Consolidated Financial Statements—(Continued)

finance leases and related obligations are initially recorded at an amount equal to the present value of future minimum lease payments computed using the Company's incremental borrowing rate or, when known, the interest rate implicit in the lease. Amortization of property under finance leases is recorded on a straight-line basis over the lease term and is included in depreciation and amortization expense.

The depreciable lives used for the principal depreciable asset classifications are:

	Estimated Useful Life
Aircraft, engines and flight simulators	25
Spare rotables and flight assemblies	7 to 25 years
Other equipment and vehicles	5 to 7 years
Internal use software	3 to 10 years
Finance leases	Lease term or estimated useful life of the asset
Leasehold improvements	Lesser of lease term or estimated useful life of the improvement
Buildings	Lesser of lease term or 30 years

As of December 31, 2023, the Company had 88 aircraft (including 15 aircraft that would have been deemed finance leases resulting in failed sale-leaseback transactions), 28 spare engines and 3 flight simulators capitalized within flight equipment with depreciable lives of 25 years. As of December 31, 2023, the Company had 117 aircraft financed through operating leases with lease terms from 4 years to 18 years. In addition, the Company had 6 spare engines financed through operating leases with lease terms from 12 years to 18 years.

    The following table illustrates the components of depreciation and amortization expense:

	Year Ended December 31,
	2023		2022		2021
	(in thousands)
Depreciation	$	218,106	$	199,118	$	193,079
Amortization of heavy maintenance	79,768		96,707		91,929
Amortization of capitalized software	22,998		17,265		12,203
Total depreciation and amortization	$	320,872	$	313,090	$	297,211

The Company capitalizes certain internal and external costs associated with the acquisition and development of internal-use software for new products, and enhancements to existing products, that have reached the application development stage and meet recoverability tests. Capitalized costs include external direct costs of materials and services utilized in developing or obtaining internal-use software, and labor cost for employees who are directly associated with, and devote time, to internal-use software projects. Capitalized computer software, included as a component of ground and other equipment in the accompanying consolidated balance sheets, net of amortization, was $53.6 million and $41.1 million at December 31, 2023 and 2022, respectively.

The Company accounts for heavy maintenance and major overhaul under the deferral method whereby the cost of heavy maintenance and major overhaul is deferred and amortized until the earlier of the end of the useful life of the related asset, the end of the remaining lease term or the next scheduled heavy maintenance event.

The Company records amortization of capitalized software on a straight-line basis within depreciation and amortization expense in the accompanying consolidated statements of operations. The Company placed in service internal-use software of $35.5 million, $25.7 million and $20.5 million, during the years ended 2023, 2022 and 2021, respectively.

Operating Lease Right-of-Use Asset and Liabilities

Right-of-use assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. Right-of-use assets and lease liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. When available, the Company uses the rate implicit in the lease to discount lease payments to present value. However, the Company's leases generally do not provide a readily determinable implicit rate. Therefore, the Company estimates the incremental borrowing rate to discount lease payments based on information available at lease commencement. The Company uses publicly available data for instruments with similar characteristics when calculating its incremental borrowing rates. The Company has options to extend certain of its operating leases for an additional period of time and options to early terminate several of its

79

Notes to Consolidated Financial Statements—(Continued)

operating leases. The lease term consists of the noncancellable period of the lease, periods covered by options to extend the lease if the Company is reasonably certain to exercise the option, periods covered by an option to terminate the lease if the Company is reasonably certain not to exercise the option and periods covered by an option to extend or not terminate the lease in which the exercise of the option is controlled by the lessor. The Company's lease agreements do not contain any residual value guarantees. The Company elected to not separate non-lease components from the associated lease component for all underlying classes of assets with lease and non-lease components.

The Company elected not to apply the recognition requirements in Topic 842 to short-term leases (i.e., leases of 12 months or less) but instead recognize these lease payments in income on a straight-line basis over the lease term. The Company elected this accounting policy for all classes of underlying assets. In addition, in accordance with Topic 842, variable lease payments are not included in the recognition of a lease liability or right-of-use asset.

Pre-Delivery Deposits on Flight Equipment

The Company is required to make pre-delivery deposit payments ("PDPs") towards the purchase price of each new aircraft and engine prior to the scheduled delivery date. These deposits are initially classified as pre-delivery deposits on flight equipment on the Company's consolidated balance sheets until the aircraft or engine is delivered, at which time the related PDPs are deducted from the final purchase price of the aircraft or engine and are reclassified to flight equipment on the Company's consolidated balance sheets.

In addition, the Company capitalizes the interest that is attributable to the outstanding PDP balances as a percentage of the related debt on which interest is incurred. Capitalized interest represents interest cost incurred during the acquisition period of a long-term asset, and is the amount which theoretically could have been avoided had the Company not paid PDPs for the related aircraft or engines.

Related interest is capitalized and included within pre-delivery deposits on flight equipment through the acquisition period until delivery is taken of the aircraft or engine and the asset is ready for service. Once the aircraft or engine is delivered, the capitalized interest is also reclassified into flight equipment on the Company's consolidated balance sheets along with the related PDPs as they are included in the cost of the aircraft or engine. Capitalized interest for 2023, 2022 and 2021 was primarily related to the interest incurred on long-term debt.

Measurement of Asset Impairments

The Company records impairment charges on long-lived assets used in operations when events and circumstances indicate that the assets may be impaired, the undiscounted future cash flows estimated to be generated by those assets are less than the carrying amount of those assets, and the net book value of the assets exceeds their estimated fair value. Factors which could be indicators of impairment include but are not limited to (1) a decision to permanently remove flight equipment or other long-lived assets from operations, (2) significant changes in the estimated useful life, (3) significant changes in projected cash flows, (4) permanent and significant declines in related fair values and (5) changes to the regulatory environment. In making these determinations, the Company uses certain assumptions, including, but not limited to: (i) estimated fair value of the assets; and (ii) estimated, undiscounted future cash flows expected to be generated by these assets, which are based on additional assumptions such as asset utilization, length of service the asset will be used in the Company’s operations, and estimated salvage values.

During 2023, the Company did not recognize impairment-related charges. During the fourth quarter of 2022, the Company made the decision to accelerate the retirement of 29 of its A319 aircraft, which were owned and unencumbered, as of December 31, 2022. In January 2023, the Company executed a purchase agreement to sell these aircraft over the next two years. The Company concluded that Management’s plan to early retire and ultimately sell these 29 A319 aircraft is an impairment indicator which required the Company to test the recoverability of the related asset group as of December 31, 2022. No impairment indicators existed and no charges were necessary under applicable accounting standards as of December 31, 2022, for the remaining flight equipment, which together represent one asset group.

The Company concluded that the net book value of this specific asset group of owned A319 aircraft is not recoverable as of December 31, 2022, due to changes to the estimated future cash flows primarily driven by the significant reductions to their remaining operating lives. As a result, during 2022, the Company recognized $333.7 million in impairment-related charges for the amount by which the carrying amount of this asset group, including the related net capitalized maintenance, exceeded its estimated fair value. During 2022, the impairment charges were recorded within special charges (credits) in the Company’s consolidated statement of operations. The fair values of these assets were determined using Level 3 fair value inputs primarily based on the agreed upon sales price for each aircraft, adjusted for estimated utilization in the period of operation from December 31, 2022 to the expected future sales date. For additional information, refer to Note 4, Special Charges and Credits.

Notes to Consolidated Financial Statements—(Continued)

Passenger Revenues

    Fare revenues. Tickets sold are initially deferred within air traffic liability ("ATL") on the Company's consolidated balance sheet. Passenger fare revenues are recognized at time of departure when transportation is provided. Generally, all tickets sold by the Company are nonrefundable. As of December 31, 2023 and 2022, the Company had ATL balances of $383.8 million and $429.6 million, respectively. As of December 31, 2023, substantially all of the ATL balance as of December 31, 2022 had been recognized. Substantially all of the Company's ATL balance as of December 31, 2023 is expected to be recognized within 12 months.

Non-fare revenues. Non-fare revenues is primarily comprised of certain ancillary items such as bags, seats and other travel-related fees, which are deemed part of the single performance obligation of providing passenger transportation. These ancillary items are recognized in non-fare revenues within passenger revenues, at the time of departure. In addition, non-fare revenues related to other travel-related programs and services provided are recognized as deemed appropriate.

The following table shows disaggregated operating revenues for the twelve months ended December 31, 2023, 2022 and 2021:

	Twelve Months Ended December 31,
	2023		2022		2021
	(in thousands)
Operating revenues:
Fare	$	2,338,191	$	2,455,817	$	1,422,927
Non-fare	2,929,970		2,533,548		1,752,875
Total passenger revenues	5,268,161		4,989,365		3,175,802
Other	94,388		79,082		54,973
Total operating revenues	$	5,362,549	$	5,068,447	$	3,230,775

Changes and cancellations. An unused ticket expires at the date of scheduled travel, at which time a service charge is assessed, and is recognized as revenue at the date of scheduled travel. However, customers may elect to change or cancel their itinerary prior to the date of departure. For changes, a service charge is recognized at time of departure of newly scheduled travel and is deducted from the face value of the original purchase price of the ticket, and the original ticket becomes invalid. For cancellations, a service charge is assessed and the amount remaining after deducting the service charge is called a credit shell which generally expires 90 days from the date the credit shell is created. Credit shells can be used towards the purchase of a new ticket and the Company’s other service offerings. Both service charge and credit shell amounts are recorded as deferred revenue and amounts expected to expire unused are estimated based on historical experience.

Estimating the amount of credits that will go unused involves some level of subjectivity and judgment. Assumptions used to generate breakage estimates can be impacted by several factors including, but not limited to, changes to the Company's ticketing policies, changes to the Company’s refund, exchange, and credit shell policies, and economic factors. The amount of credit shells issued varies, primarily due to the flight delays and cancellation events throughout the year. The Company generally experiences some variability in the amount of breakage revenue recognized throughout the year and expects some variability in the amount of breakage revenue recorded in future periods, as the estimates of the portion of those funds that will expire unused may differ from historical experience.

Other Revenues

Other revenues primarily consist of the marketing component of the sale of loyalty points to the Company's credit card partner and commissions revenue from the sale of various items such as hotels and rental cars.

Loyalty Program

The Company operates the Free Spirit loyalty program (the "Free Spirit Program"), which attracts members and partners and builds customer loyalty for the Company by offering a variety of awards, benefits and services. Free Spirit Program members earn and accrue points for dollars spent on Spirit for flights and other non-fare services as well as services from non-air partners such as retail merchants, hotels or car rental companies or by making purchases with credit cards issued by partner banks and financial services providers. Points are redeemable by customers in future periods for air travel on Spirit.

81

Notes to Consolidated Financial Statements—(Continued)

    To reflect the point credits earned, the program includes two types of transactions that are considered revenue arrangements with multiple performance obligations: (1) points earned with travel and (2) points sold to its co-branded credit card partner.

    Passenger ticket sales earning points. Passenger ticket sales earning points provide customers with (1) points earned and (2) air transportation. The Company values each performance obligation on a stand-alone basis and allocates the consideration to each performance obligation based on their relative fair value. To value the point credits earned, the Company considers the quantitative value a passenger receives by redeeming points for a ticket rather than paying cash, which is referred to as equivalent ticket value ("ETV").

The Company defers revenue for the points when earned and recognizes loyalty travel awards in passenger revenue as the points are redeemed and services are provided. The Company records the air transportation portion of the passenger ticket sales in air traffic liability and recognizes passenger revenue when transportation is provided or if the ticket goes unused, at the date of scheduled travel.

    Sale of points. Customers may earn points based on their spending with the Company's co-branded credit card company with which the Company has an agreement to sell points. The contract to sell points under this agreement has multiple performance obligations, as discussed below.

The Company's co-branded credit card agreement provides for joint marketing where cardholders earn points for making purchases using co-branded cards. During 2023, the Company extended its agreement with the administrator of the Free Spirit affinity credit card program through December 31, 2028. The Company accounts for this agreement consistently with the accounting method that allocates the consideration received to the individual products and services delivered. The value is allocated based on the relative stand-alone selling prices of those products and services, which generally consists of (i) points to be awarded, (ii) airline benefits, (iii) licensing of brand and access to member lists and (iv) advertising and marketing efforts. The Company determined the estimate of the stand-alone selling prices by considering discounted cash flow analysis using multiple inputs and assumptions, including: (1) the expected number of points awarded and number of points redeemed, (2) the estimated stand-alone selling price of the award travel obligation and airline benefits, (3) licensing of brand access to member lists and (4) the cost of advertising and marketing efforts undertaken by the Company.

The Company defers the amount for award travel obligation as part of loyalty deferred revenue. These amounts that are expected to be redeemed during the following twelve months are recorded within ATL on the consolidated balance sheet and the portion that is not expected to be redeemed during the following twelve months is recorded within long-term liabilities on the consolidated balance sheet. In addition, the Company recognizes loyalty travel awards in passenger revenue as the points are used for travel. Revenue allocated to advertising and the remaining performance obligations, primarily marketing components, is recorded in other revenue over time as points are delivered. Total unrecognized revenue from future Free Spirit Program was $104.6 million and $81.3 million at December 31, 2023 and 2022, respectively. The current portion of this balance is recorded within air traffic liability and the long-term portion of this balance is recorded within deferred gains and other long-term liabilities in the accompanying consolidated balance sheets.

    The following table illustrates total cash proceeds received from the sale of points and the portion of such proceeds recognized in non-ticket revenue immediately as marketing component:

	Consideration received from credit card loyalty programs		Portion of proceeds recognized immediately as marketing component
Year Ended	(in thousands)
December 31, 2023	$	93,147	$	48,071
December 31, 2022	80,970		40,987
December 31, 2021	48,035		23,681

    Points breakage. For points that the Company estimates are not likely to be redeemed ("breakage"), the Company recognizes the associated value proportionally during the period in which the remaining points are redeemed. Management uses statistical models to estimate breakage based on historical redemption patterns. A change in assumptions as to the period over which points are expected to be redeemed, the actual redemption activity for points or the estimated fair value of points expected to be redeemed could have an impact on revenues in the year in which the change occurs and in future years.

82

Notes to Consolidated Financial Statements—(Continued)

    Current activity of loyalty program. Points are combined in one homogeneous pool and are not separately identifiable. As such, revenue is composed of points that were part of the loyalty deferred revenue balance at the beginning of the period as well as points that were issued during the period.

Airframe and Engine Maintenance

The Company accounts for heavy maintenance and major overhaul under the deferral method whereby the cost of heavy maintenance and major overhaul is deferred and amortized until the earlier of the end of the useful life of the related asset, the end of the remaining lease term or the next scheduled heavy maintenance event.

Amortization of heavy maintenance and major overhaul costs charged to depreciation and amortization expense was $79.8 million, $96.7 million and $91.9 million for the years ended 2023, 2022 and 2021, respectively. During the years ended 2023, 2022 and 2021, the Company deferred $202.9 million, $149.3 million and $74.1 million, respectively, of costs for heavy maintenance. As of December 31, 2023 and 2022, the Company had a deferred heavy maintenance balance of $529.8 million and $349.0 million, and accumulated heavy maintenance amortization of $216.2 million and $158.6 million, respectively.

The Company outsources certain routine, non-heavy maintenance functions under contracts that require payment on a utilization basis, primarily based on flight hours. Costs incurred for maintenance and repair under flight hour maintenance contracts, where labor and materials price risks have been transferred to the service provider, are expensed based on contractual payment terms. All other costs for routine maintenance of the airframes and engines are charged to expense as performed.

The table below summarizes the components of the Company’s maintenance cost:

	Year Ended December 31,
	2023		2022		2021
	(in thousands)
Utilization-based maintenance expense	$	117,458	$	97,930	$	81,591
Non-utilization-based maintenance expense	105,881		89,890		77,911
Total maintenance, materials and repairs	$	223,339	$	187,820	$	159,502

Leased Aircraft Return Costs

The Company's aircraft lease agreements often contain provisions that require the Company to return aircraft airframes, engines and other aircraft components to the lessor in a certain condition or pay an amount to the lessor based on the airframe and engine's actual return condition. Lease return costs include all costs that would be incurred at the return of the aircraft, including costs incurred to repair the airframe and engines to the required condition as stipulated by the lease. Lease return costs are recognized beginning when it is probable that such costs will be incurred and they can be estimated.

When determining the probability to accrue lease return costs, there are various estimated cost and factors which need to be considered such as the contractual terms of the lease agreement, current condition of the aircraft, the age of the aircraft at lease expiration, projected number of hours run on the engine at the time of return, and the number of projected cycles run on the airframe at the time of return, among others. Management assesses the need to accrue lease return costs periodically throughout the year or whenever facts and circumstances warrant an assessment. Lease return costs will generally be estimable closer to the end of the lease term but may be estimable earlier in the lease term depending on the contractual terms of the lease agreement and the timing of maintenance events for a particular aircraft.

Aircraft Fuel

Aircraft fuel expense includes jet fuel and associated into-plane costs, taxes, and oil, and realized and unrealized gains and losses associated with fuel derivative contracts, if any.

Advertising

The Company expenses advertising and the production costs of advertising as incurred. Marketing and advertising expenses of $9.0 million, $9.2 million and $7.1 million for the years ended 2023, 2022 and 2021, respectively, were recorded within distribution expense in the consolidated statements of operations.

Income Taxes

The Company accounts for income taxes using the asset and liability method. The Company records a valuation allowance to reduce the deferred tax assets reported if, based on the weight of the evidence, it is more likely than not that some

83

Notes to Consolidated Financial Statements—(Continued)

portion or all of the deferred tax assets will be not realized. As of December 31, 2023 and 2022, the Company had a valuation allowance of $17.7 million and $10.9 million, respectively, recorded within deferred income taxes on the Company's consolidated balance sheets. For additional information, refer to Note 16, Income Taxes.

Stock-Based Compensation

The Company recognizes cost of employee services received in exchange for awards of equity instruments based on the fair value of each instrument at the date of grant. For the majority of awards, compensation expense is recognized on a straight-line basis over the period during which an employee is required to provide service in exchange for an award. Certain awards have performance conditions that must be achieved prior to vesting and are expensed based on the expected achievement at each reporting period. The Company has issued restricted stock awards, performance share awards, market share awards and performance and market share awards. Restricted stock awards are valued at the fair value of the shares on the date of grant. The fair value of performance share awards based on a market condition and the market share awards are estimated through the use of a Monte Carlo simulation model. The fair value of performance share awards based on a performance condition is based on the fair value of the shares on the date of grant. The performance share awards based on a performance condition are evaluated at each report date and adjustments are made to stock-based compensation expense based on the number of shares deemed probable of issuance upon vesting. The fair value of the market and performance share awards are estimated through the use of a Monte Carlo simulation model and adjusted based on the number of shares deemed probable of issuance upon vesting. For additional information, refer to Note 11, Stock-Based Compensation.

Payroll Support Program

During 2020 and 2021, in order to assist the Company to pay for salaries, wages and benefits for its employees, the Company entered into three separate Payroll Support Program Agreements under the CARES Act (“PSP1”), as extended by the Consolidated Appropriations Act of 2021 (“PSP2”) and the American Rescue Plan Act (“PSP3”) with the Treasury. The agreements provided the Company with grants (refer to Note 4, Special Charges and Credits for additional information), unsecured term loans (refer to Note 13, Debt and Other Obligations for additional information) and warrants (refer to Note 10, Equity for additional information). The funds provided were used exclusively to pay for salaries, wages and benefits for the Company's employees. As of December 31, 2023, the Company is in compliance with the terms of the PSP1, PSP2 and PSP3.

Concentrations of Risk

The Company’s business may be adversely affected by increases in the price of aircraft fuel, the volatility of the price of aircraft fuel, or both. Aircraft fuel, one of the Company’s largest expenditures, represented approximately 31%, 34% and 28% of total operating expenses in 2023, 2022 and 2021, respectively.

The Company’s operations are largely concentrated in the southeast United States with Fort Lauderdale being the highest volume fueling point in the system. Gulf Coast Jet indexed fuel is the basis for a substantial majority of the Company’s fuel consumption. Any disruption to the oil production or refinery capacity in the Gulf Coast, as a result of weather or any other disaster, or disruptions in supply of jet fuel, dramatic escalations in the costs of jet fuel and/or the failure of fuel providers to perform under fuel arrangements for other reasons could have a material adverse effect on the Company’s financial condition and results of operations.

The Company’s operations will continue to be vulnerable to weather conditions (including hurricane season or snow and severe winter weather), which could disrupt service or create air traffic control problems. These events may result in decreased revenue and/or increased costs.

The Company relies on a limited number of vendors for the delivery of additional aircraft and engines - currently Airbus A320-family, single-aisle aircraft, powered by engines manufactured by IAE and Pratt & Whitney. Due to the relatively small size of the Company's fleet and high utilization rate, the unavailability of aircraft and engines, as well as the reduced capacity, resulting from delivery delays or performance issues from these vendors, could have a material adverse effect on the Company’s business, results of operations and financial condition. Refer to Note 3, Current Developments, for additional information on the Pratt & Whitney engine performance issues.

As of December 31, 2023, the Company had six union-represented employee groups that together represented approximately 85% of all employees. The Company's aircraft maintenance technicians are represented by AMFA. The related collective bargaining agreement is currently under negotiation. A strike or other significant labor dispute with the Company’s unionized employees is likely to adversely affect the Company’s ability to conduct business. Additional disclosures are included in Note 17, Commitments and Contingencies.

3.Current Developments

JetBlue Merger

On July 28, 2022, Spirit entered into an Agreement and Plan of Merger (the “Merger Agreement”) with JetBlue Airways Corporation, a Delaware corporation (“JetBlue”), and Sundown Acquisition Corp., a Delaware corporation and a direct, wholly owned subsidiary of JetBlue (“Merger Sub”), pursuant to which and subject to the terms and conditions therein, Merger Sub will merge with and into Spirit, with Spirit continuing as the surviving entity (the “Merger”). As a result of the Merger, each outstanding share of Spirit's common stock (except for dissenting shares, treasury stock, and shares of Spirit's common stock owned by JetBlue, Merger Sub or any of their respective wholly owned subsidiaries), will be converted into the right to receive an amount in cash per share, without interest, equal to (such amount, the “Merger Consideration”) (i) $33.50 minus (ii) (A) $2.50 (the “Approval Prepayment Amount”), paid on October 26, 2022 following the adoption by Spirit stockholders of the Merger Agreement on October 19, 2022 and (B) an additional monthly per share prepayment amount calculated as the product of $0.10 and the number of additional prepayments paid (or, in the event the Closing occurs after the record date of, but before the payment date of any such additional prepayment, to the extent payable after the Closing), not to exceed $1.15 per share of Spirit common stock, by JetBlue to Spirit stockholders in accordance with the Merger Agreement (each such payment is referred to as an “Additional Prepayment” and such $0.10 amount is referred to as the “Additional Prepayment Amount”). If an aggregate of $1.15 of Additional Prepayment Amounts has been paid out before consummation or termination of the Merger, Spirit stockholders will thereafter continue to receive monthly Additional Prepayments, at the same $0.10 per month rate, until the transaction closes or the Merger Agreement is terminated. The Merger Agreement becomes unilaterally terminable by either JetBlue or Spirit after July 24, 2024.

In accordance with the terms of the Merger Agreement, JetBlue is required to pay or cause to be paid the Approval Prepayment Amount to Spirit stockholders as of the record date established by Spirit for the special meeting to approve the Merger Agreement within five business days following such Spirit stockholder approval. Thereafter, on or prior to the last business day of each month beginning after December 31, 2022 until the earlier of the Closing or termination of the Merger Agreement, JetBlue will also pay or cause to be paid the Additional Prepayment Amount to Spirit stockholders as of a record date not more than five business days prior to the last business day of such month. Payments made from JetBlue to Spirit stockholders do not impact the Company's results of operations or cash flows.

On October 19, 2022, Spirit’s stockholders approved the Merger Agreement at a special meeting of stockholders. The record date for both the Company’s special meeting and the Approval Prepayment was September 12, 2022. In accordance with the terms of the Merger Agreement, on October 26, 2022, JetBlue paid the Spirit stockholders the Approval Prepayment Amount of $2.50 per share. Additionally, beginning January 2023, JetBlue paid on a monthly basis the Additional Prepayments of $0.10 per share of common stock to all Spirit stockholders as of each record date, per the Merger Agreement.

Due to the payment of the Approval Prepayment and each of the Additional Prepayment Amounts, in accordance with the terms of the respective debt indentures and warrant agreements, the Company announced related adjustments to the conversion rates of its convertible notes due 2025 and its convertible notes due 2026 as well as adjustments to the exercise prices and warrant shares of the PSP1, PSP2 and PSP3 warrants outstanding. As of December 31, 2023, the conversion rates of the convertible notes due 2025 and 2026 were 94.9262 and 24.6649 shares of voting common stock per $1,000 principal

85

Notes to Consolidated Financial Statements—(Continued)

amount of convertible notes, respectively. In addition, as of December 31, 2023, the exercise prices of the PSP1, PSP2 and PSP3 warrants were $11.663, $20.229 and $30.196, respectively, and the number of warrant shares issuable upon the exercise of the PSP1, PSP2 and PSP3 warrants were adjusted to 628,725.19, 166,292.37 and 97,219.73, respectively.

Completion of the Merger is subject to the satisfaction or waiver of certain closing conditions, including, among other things: (1) approval of the transactions by Spirit’s stockholders, which was received on October 19, 2022; (2) receipt of applicable regulatory approvals, including approvals from the U.S. Federal Communications Commission, the U.S. Federal Aviation Administration and the U.S. Department of Transportation ("DOT") and the expiration or early termination of the statutory waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and other competition laws, and other required regulatory approvals; (3) the absence of any law or order prohibiting the consummation of the transactions; and (4) the absence of any material adverse effect (as defined in the Merger Agreement) on Spirit.

On March 7, 2023, the U.S. Department of Justice (“DOJ”) filed suit to block the Merger and a trial was held in late 2023. On January 16, 2024, the United States District Court for the District of Massachusetts (the “District Court”) granted a permanent injunction against the Merger (the "Injunction"). On January 19, 2024, Spirit and JetBlue filed a notice of appeal to reverse the District Court's decision and allow Spirit and JetBlue to complete the Merger. On January 25, 2024, JetBlue made a public filing stating that certain closing conditions required by the Merger Agreement may not be satisfied prior to the outside dates set forth in the Merger Agreement and, accordingly, the Merger Agreement may be terminable on and after January 28, 2024. The Company does not believe there is a basis for terminating the Merger Agreement, and will continue to abide by all of its obligations under the Merger Agreement. On January 29, 2024, Spirit and JetBlue filed a request with the U.S. Court of Appeals for the First Circuit (the "Court of Appeals") seeking an expedited schedule for their appeal. On February 2, 2024, the Court of Appeals granted our motion, stating it would hear arguments in June 2024.

In addition, Spirit has agreed, among other things, that neither it nor any of its directors, officers, employees and representatives will (1) solicit alternative transactions, (2) participate in any discussions or negotiations relating to alternative transactions, (3) furnish any non-public information in connection with alternative transactions or (4) enter into any agreement relating to alternative transactions, except under limited circumstances described in the Merger Agreement. However, in certain circumstances, Spirit may terminate the Merger Agreement to enter into a definitive agreement for a Superior Proposal (as defined in the Merger Agreement). In addition, Spirit, JetBlue and Merger Sub each make certain customary representations, warranties and covenants, as applicable, in the Merger Agreement.

The Merger Agreement contains certain termination rights for Spirit and JetBlue, including, without limitation, a right for either party to terminate if the Merger is not consummated on or before July 28, 2023 (the "Outside Date"), subject to certain automatic extensions up to July 24, 2024 if needed to obtain regulatory approvals. Since all regulatory approvals required to consummate the Merger were not obtained as of July 28, 2023 and January 28, 2024, the current Outside Date has been automatically extended to July 24, 2024. Upon the termination of the Merger Agreement under specified circumstances, Spirit will be required to pay JetBlue a termination fee of $94.2 million. Upon the termination of the Merger Agreement by JetBlue because of a material uncured breach by Spirit of the Merger Agreement, Spirit will be required to pay JetBlue an amount equal to the sum of all amounts paid by JetBlue to the Spirit stockholders. Upon the termination of the Merger Agreement for failure to obtain antitrust regulatory clearance, JetBlue will be required to pay (i) to Spirit, $70.0 million, and (ii) to the Spirit stockholders, the excess of (A) $400.0 million minus (B) the sum of the Approval Prepayment Amount and all Additional Prepayment Amounts previously paid by JetBlue to the Spirit stockholders.

Pratt & Whitney

On July 25, 2023, RTX Corporation, parent company of Pratt & Whitney, announced that it had determined that a rare condition in the powdered metal used to manufacture certain engine parts will require accelerated inspection of the PW1100G-JM ("GTF") fleet, which powers the Company's A320neo family of aircraft.

In September 2023, Pratt & Whitney notified the Company that all the GTF neo engines in its fleet, including the engines slotted for future aircraft deliveries, for a yet to be determined period, are subject to the inspection and possible replacement, of the powdered metal high-pressure turbine and compressor discs. In addition, Pratt & Whitney issued a special instruction ("SI"), requiring accelerated engine removals and inspections covering the initial tranche of operational engines, no later than September 15, 2023. As of December 31, 2023, in accordance with the SI issued by Pratt & Whitney, the Company has removed five engines from service, three of which are currently awaiting induction for inspection. For the remaining engines, Pratt & Whitney has provided an initial analysis on an inspection and removal schedule for these engines.

In addition, to the 5 engines removed from service, the Company had 12 neo aircraft grounded as of December 31, 2023 for reliability, durability, and inspection requirements combined. The Company currently estimates the majority of the affected

86

Notes to Consolidated Financial Statements—(Continued)

engines will require removal and inspection in 2024, but continuing through 2026, based on service bulletins ("SB") issued by Pratt & Whitney and related airworthiness directives issued by the FAA.

The temporary removal of engines from service is expected to drive a significant decrease in the Company's near-term growth projections. The Company has reduced capacity in amounts and timing commensurate with the initially scheduled removal and inspection of these impacted engines, however, the Company continues to assess the impact on its future capacity plans. Pratt & Whitney stated that they are focused on addressing the challenges arising from the powdered metal manufacturing issue and will proactively take steps to support and mitigate the operational impact to its customers. The Company has begun discussions with Pratt & Whitney regarding compensation for the loss of utilization; however, the amount, timing, or structure of the compensation that will be agreed upon is not yet known.

4.Special Charges and Credits

During the twelve months ended December 31, 2023, the Company recorded $50.0 million within special charges (credits) on the Company's consolidated statements of operations, in legal, advisory and other fees related to the Merger Agreement with JetBlue entered into on July 28, 2022. In addition, as part of the Merger Agreement with JetBlue, the Company implemented an employee retention award program (the "JetBlue Retention Award Program") during the third quarter of 2022. The target retention award is payable to the Company's employees upon the successful close of the Merger. In the event the Merger fails or is abandoned, 50% of the target retention award will be paid to the Company's employees. This amount will be paid to the Company's employees in two installments. The first installment was paid in July 2023 and the second installment is payable in July 2024 or upon termination or abandonment of the Merger, whichever comes first. During the twelve months ended December 31, 2023, the Company recorded $19.5 million within special charges (credits) on the Company's consolidated statements of operations, related to the JetBlue Retention Award Program.

During the twelve months ended December 31, 2022, the Company recorded $333.7 million within special charges (credits) on the Company's consolidated statements of operations in impairment charges related to the planned acceleration of the retirement of 29 of its A319 aircraft.

As part of the Former Frontier Merger Agreement, the Company implemented an employee retention award program (the "Frontier Retention Award Program"). On July 27, 2022, the Frontier Merger Agreement was mutually terminated; therefore, 50% of the target retention bonus was awarded to the Company's employees during the third quarter of 2022. In addition, as part of the JetBlue Merger Agreement, the Company implemented the JetBlue Retention Award Program during the third quarter of 2022.

During the twelve months ended December 31, 2021, the Company recorded a $342.2 million credit, net of the related costs, within special charges (credits) on the Company’s consolidated statements of operations related to the grant component of the PSP2 and PSP3 agreements with the Treasury.

In addition, during the twelve months ended December 31, 2021, the Company recorded a credit of $37.5 million related to the CARES Act Employee Retention credit within special charges (credits) on the Company’s consolidated statements of operation. These special credits were partially offset by $2.0 million in special charges recorded during the twelve months ended December 31, 2021 related to salaries, wages and benefits paid to rehired employees, previously terminated with the Company's involuntary employee separation program, in compliance with the restrictions of PSP2 and PSP3.

5. Loss on Disposal of Assets

During the twelve months ended December 31, 2023, the Company recorded $34.0 million in loss on disposal of assets in the consolidated statement of operations. During December 2023, the Company completed 20 sale-leaseback transactions (on aircraft previously owned by the Company) of which, 6 resulted in operating leases and 14 would have been deemed finance leases resulting in failed sale-leaseback transactions. As a result of the 6 sale-leaseback transactions that resulted in operating leases, the Company recorded a related loss of $32.1 million within loss on disposal of assets. Refer to Note 14, Leases for additional information on the 20 sale-leaseback transactions. Loss on disposal of assets for the twelve months ended December 31, 2023 also included a $3.0 million net gain recorded as a result of 10 aircraft sale-leaseback transactions related to new aircraft deliveries completed during the twelve months ended December 31, 2023.

In addition, during the fourth quarter 2022, the Company made the decision to accelerate the retirement of 29 of its A319 aircraft and, in January 2023, the Company executed a sale agreement to sell these aircraft over the next two years. During the twelve months ended December 31, 2023, the Company completed the sale of 12 A319 airframes and 20 A319 engines and recorded a related net loss of $1.6 million. The remaining A319 aircraft and engines subject to the sale agreement remain in service and will continue to operate until immediately before the sale of the aircraft. In addition, the Company recorded a $3.3 million loss primarily related to the disposal of obsolete assets.

During the twelve months ended December 31, 2022, the Company recorded $46.6 million in loss on disposal of assets in the consolidated statement of operations. This loss on disposal of assets mainly consisted of $38.5 million related to the loss on 16 aircraft sale-leaseback transactions completed during 2022 and $6.6 million related to the impairment of 1 spare engine during the first quarter of 2022 which was damaged beyond economic repair.

During the twelve months ended December 31, 2021, the Company recorded $3.3 million in loss on disposal of assets in the consolidated statement of operations. This loss on disposal of assets mainly consisted of $2.3 million related to the loss on five aircraft sale-leaseback transactions completed during 2021 and $1.1 million related to the loss on the sale of auxiliary power units ("APUs").

6.Letters of Credit

As of December 31, 2023, the Company had $85.0 million in standby letters of credit secured by $75.0 million of restricted cash, of which $55.9 million were issued letters of credit. As of December 31, 2022, the Company had a $85.0 million standby letters of credit secured by $75.0 million restricted cash, of which $31.0 million were issued letters of credit.

7.Credit Card Processing Arrangements

The Company has agreements with organizations that process credit card transactions arising from the purchase of air travel, baggage charges and other ancillary services by customers. As it is standard in the airline industry, the Company's contractual arrangements with credit card processors permit them, under certain circumstances, to retain a holdback or other collateral, when future air travel and other future services are purchased via credit card transactions. The required holdback is the percentage of the Company's overall credit card sales that its credit card processors hold to cover refunds to customers if the Company fails to fulfill its flight obligations.

The Company's credit card processors do not require the Company to maintain cash collateral provided that the Company satisfies certain liquidity and other financial covenants. Failure to meet these covenants would provide the processors the right to place a holdback, resulting in a commensurate reduction of unrestricted cash. As of December 31, 2023 and 2022, the Company was in compliance with such liquidity and other financial covenants in its credit card processing agreements, and the processors were holding back no remittances.

The maximum potential exposure to cash holdbacks by the Company's credit card processors, based upon advance ticket sales and Spirit Saver$ Club® memberships as of December 31, 2023 and 2022, was $408.3 million and $468.5 million, respectively.

These securities are stated at fair value within current assets on the Company's consolidated balance sheet. Realized gains and losses on sales of investments, if any, are reflected in non-operating other (income) expense in the consolidated statements of operations. Unrealized gains and losses on investment securities are reflected as a component of accumulated other comprehensive income, ("AOCI").

As of December 31, 2023 and December 31, 2022, the Company had $112.5 million and $107.1 million, respectively, in short-term available-for-sale investment securities.

The 739,089 warrants issued in connection with the PSP1, PSP2 and PSP3 agreements represent less than 1% of the outstanding shares of the Company's common stock as of December 31, 2023.

The Company concluded that the PSP1, PSP2 and PSP3 warrant agreement are a derivative contract classified within equity, at fair value upon issuance, within the Company’s consolidated balance sheet.

Stock-based compensation cost amounted to $12.0 million, $11.5 million and $12.5 million for 2023, 2022 and 2021, respectively. During 2023, 2022 and 2021 there was a $2.4 million, $2.4 million and $1.2 million tax benefit recognized in income related to stock-based compensation.

Restricted Stock and Restricted Stock Units

Restricted stock and restricted stock unit awards are valued at the fair value of the shares on the date of grant. Generally, granted shares and units vest over a two to four year graded vesting period. Each restricted stock unit represents the right to receive one share of common stock upon vesting of such restricted stock unit. Vesting of restricted stock units is based on time-based service conditions. In order to vest, the participant must still be employed by the Company, with certain contractual exclusions, at each vesting event. Generally, within 30 days after vesting, the shares underlying the award will be issued to the participant. In the event a successor corporation in a change in control situation fails to assume or substitute for the restricted stock units, the restricted stock units will automatically vest in full as of immediately prior to the consummation of such change in control. In the event of death or permanent disability of a participant, the restricted stock units will automatically vest in full. Compensation expense is recognized on a straight-line basis over the requisite service period.

A summary of the status of the Company’s restricted stock shares (restricted stock awards and restricted stock unit awards) as of December 31, 2023 and changes during the year ended December 31, 2023 is presented below:

	Number of Shares	Weighted-Average Grant Date Fair Value ($)
Outstanding at December 31, 2022	624,452	24.76
Granted	500,648	19.58
Vested	(372,788)	25.53
Forfeited	(46,424)	21.04
Outstanding at December 31, 2023	705,888	20.93

There were 500,648 and 404,062 restricted stock shares granted during the years ended December 31, 2023 and December 31, 2022, respectively. As of December 31, 2023 and December 31, 2022, there was $8.4 million and $8.6 million, respectively, of total unrecognized compensation cost related to nonvested restricted stock to be recognized over 1.8 years and 1.7 years, respectively.

The weighted-average fair value of restricted stock granted during the years ended December 31, 2023, 2022 and 2021 was $19.58, $23.48 and $25.17, respectively. The total fair value of restricted stock shares vested during the years ended December 31, 2023, 2022 and 2021 was $7.2 million, $7.5 million and $4.6 million, respectively.

Performance and Market Share Awards

The Company grants certain executives performance and market stock units that vest based on either market, performance or market and performance conditions as part of a long-term incentive plan. The number of shares of common stock underlying each award is determined at the end of the performance period. In order to vest, the executive must still be employed by the Company, with certain contractual exclusions, at the end of the performance period.

Stock-based compensation cost related to these awards amounted to $3.0 million, $1.5 million and $3.5 million for 2023, 2022 and 2021, respectively. As of December 31, 2023 and 2022, there was $3.9 million and $3.0 million, respectively, of total unrecognized compensation cost related to nonvested performance and market share awards expected to be recognized over 1.8 years and 1.6 years, respectively.

13. Debt and Other Obligations

Long-term debt

    As of December 31, 2023, the Company had outstanding public and non-public debt instruments.

Revolving credit facility due in 2025

As of both December 31, 2023 and December 31, 2022, the Company had $300.0 million undrawn and available under its revolving credit facility. Any amounts drawn on this facility are included in long-term debt and finance leases, less current maturities, on the Company's consolidated balance sheets. During the fourth quarter 2023, the Company amended the agreement to extend the final maturity of the facility to September 30, 2025 and adjust other terms.

The Company may pledge the following types of assets as collateral to secure its obligations under the revolving credit facility: (i) certain take-off and landing rights of the Company at LaGuardia Airport, (ii) certain eligible aircraft spare parts and ground support equipment, (iii) aircraft, spare engines and flight simulators, (iv) real property assets and (v) cash and cash equivalents. The revolving credit facility bears variable interest based on SOFR, plus a 2.00% margin per annum, or another rate, at the Company's election, based on certain market interest rates, plus a 1.00% margin per annum, in each case with a floor of 0%.

The 2025 revolving credit facility requires the Company to maintain (i) so long as any loans or letters of credit are outstanding under the 2025 revolving credit facility, unrestricted cash, cash equivalents, short-term investment securities and unused commitments available under all revolving credit facilities (including the 2025 revolving credit facility) aggregating not less than $450.0 million, of which no more than $300.0 million may be derived from unused commitments under the 2025 revolving credit facility, (ii) a minimum ratio of the borrowing base of the collateral described above (determined as the sum of a specified percentage of the appraised value of each type of such collateral) to outstanding obligations under the 2025 revolving credit facility of not less than 1.0 to 1.0 (if the Company does not meet the minimum collateral coverage ratio, it must either provide additional collateral to secure its obligations under the 2025 revolving credit facility or repay the loans under the 2025 revolving credit facility by an amount necessary to maintain compliance with the collateral coverage ratio), and (iii) the pledged take-off and landing rights of the Company at LaGuardia Airport and a specified number of spare engines in the collateral described above so long as any loans or letters of credit are outstanding under the 2025 revolving credit facility.

Convertible senior notes due 2025

On May 12, 2020, the Company completed the public offering of $175.0 million aggregate principal amount of 4.75% convertible senior notes due 2025 ("convertible notes due 2025").

Notes to Financial Statements—(Continued)

Noteholders may convert their notes at their option only in the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on June 30, 2020 (and only during such calendar quarter), if the last reported sale price per share of the Company’s common stock exceeds 130% of the conversion price for each of at least 20 trading days (whether or not consecutive) during the 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter; (2) during the five consecutive business days immediately after any five consecutive trading day period (such five consecutive trading day period, the “measurement period”) in which the trading price per $1,000 principal amount of notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price per share of the Company’s common stock on such trading day and the conversion rate on such trading day; (3) upon the occurrence of certain corporate events or distributions on the Company’s common stock; and (4) at any time from, and including, February 18, 2025 until the close of business on the second scheduled trading day immediately before the maturity date. As of December 31, 2023, the notes may be converted by noteholders through March 31, 2024.

Based on the terms of the indenture, upon conversion, the Company will pay or deliver, as the case may be, cash, shares of the Company’s common stock or a combination of cash and shares of common stock, at the Company’s election. However, based on the terms of Merger Agreement with JetBlue, upon conversion of any convertible notes due 2025 through the closing or termination of the Merger Agreement with JetBlue, the conversion value, including the principal amount, will be paid all in shares of the Company's common stock. The initial conversion rate was 78.4314 shares of voting common stock per $1,000 principal amount of convertible notes (equivalent to an initial conversion price of approximately $12.75 per share of common stock). The conversion rate will be subject to adjustment in some events but will not be adjusted for any accrued and unpaid interest. Due to the payment of the Approval Prepayment and Additional Prepayment Amounts paid by JetBlue to the Company's stockholders, in accordance with the terms of the indenture, the Company has announced related adjustments to the conversion rate of its convertible senior notes due 2025. As of December 31, 2023, the conversion rate was 94.9262 shares of voting common stock per $1,000 principal amount of convertible notes (equivalent to a conversion price of approximately $10.53 per share of common stock). Refer to Note 3, Current Developments for additional information on the Approval Prepayment and Additional Prepayment Amounts.

During the first quarter of 2023, $0.3 million of the Company's convertible notes due 2025 were converted to 27,204 shares of the Company's voting common stock. As of December 31, 2023, the Company had recorded $0.3 million, net of issuance costs and common stock, in additional paid-in-capital on its consolidated balance sheets related to the conversion of these notes. Since the notes are currently convertible in accordance with the terms of the indenture governing such notes, the Company had $25.1 million recorded within current maturities of long-term debt and finance leases on its consolidated balance sheets as of December 31, 2023 related to its convertible notes due 2025. As of December 31, 2023, the if-converted value exceeds the principal amount of the convertible notes due 2025 by $14.2 million using the average stock price for the twelve months ended December 31, 2023.

Convertible senior notes due 2026

On April 30, 2021, the Company completed the public offering of $500.0 million aggregate principal amount of 1.00% convertible senior notes due 2026 ("convertible notes due 2026").

Noteholders may convert their notes at their option only in the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on June 30, 2021 (and only during such calendar quarter), if the last reported sale price per share of the Company’s common stock exceeds 130% of the conversion price for each of at least 20 trading days (whether or not consecutive) during the 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter; (2) during the five consecutive business days immediately after any five consecutive trading day period (such five consecutive trading day period, the “measurement period”) in which the trading price per $1,000 principal amount of notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price per share of the Company’s common stock on such trading day and the conversion rate on such trading day; (3) upon the occurrence of certain corporate events or distributions on the Company’s common stock; (4) if the Company calls such notes for redemption; and (5) at any time from, and including, February 17, 2026 until the close of business on the second scheduled trading day immediately before the maturity date. As of December 31, 2023, the notes did not qualify for conversion by noteholders through March 31, 2024.

Based on the terms of the indenture, the Company will have the right to elect to settle conversions in cash, shares of the Company's common stock or a combination of cash and shares of common stock. Upon conversion of any notes, the Company will pay the conversion value in cash up to at least the principal amount of the notes being converted. However, based on the terms of the Merger Agreement with JetBlue, upon conversion of any convertible notes due 2026 through the closing or termination of the Merger Agreement with JetBlue, the conversion value, including the principal amount, will be paid all in cash. The conversion value will be determined over an observation period consisting of 40 trading days. The initial conversion rate

94

Notes to Financial Statements—(Continued)

was 20.3791 shares of voting common stock per $1,000 principal amount of convertible notes (equivalent to an initial conversion price of approximately $49.07 per share of common stock). The conversion rate will be subject to adjustment in some events but will not be adjusted for any accrued and unpaid interest. Due to the payment of the Approval Prepayment and Additional Prepayment Amounts paid by JetBlue to the Company's stockholders, in accordance with the terms of the indenture, the Company has announced related adjustments to the conversion rate of its convertible senior notes due 2026. As of December 31, 2023, the conversion rate was 24.6649 shares of voting common stock per $1,000 principal amount of convertible notes (equivalent to a conversion price of approximately $40.54 per share of common stock). Refer to Note 3, Current Developments for additional information on the Approval Prepayment and Additional Prepayment Amounts.

The Merger Agreement with JetBlue includes settlement terms for any conversion of the convertible notes due 2026, as described above, that cause the conversion option, which is an embedded derivative, not to qualify for the derivative accounting scope exception provided under ASC 815. As such, the Company bifurcated the fair value of the conversion option of the convertible senior notes due 2026 as a derivative liability with subsequent changes in fair value recorded in earnings. The Company recorded the fair value of the embedded derivative of $49.5 million as a derivative liability within deferred gains and other long-term liabilities and a debt discount within long-term debt and finance leases, less current maturities on its consolidated balance sheets. The debt discount will continue to be amortized through interest expense, using the effective interest rate method, over the remaining life of the instrument.

Since the notes are currently not convertible in accordance with the terms of the indenture governing such notes, the Company had $472.6 million, net of the related unamortized debt discount of $27.4 million, recorded within long-term debt and finance leases, less current maturities on the Company's consolidated balance sheets as of December 31, 2023 related to its convertible notes due 2026. For additional information, refer to Note 18, Fair Value Measurements.

Adoption of ASU No. 2020-06

In August 2020, the FASB issued ASU No. 2020-06, "Accounting for Convertible Instruments and Contracts in an Entity's Own Equity." This standard simplifies and adds disclosure requirements for the accounting and measurement of convertible instruments. It eliminates the treasury stock method for convertible instruments and requires application of the “if-converted” method for certain agreements when computing earnings per share. In addition, the standard eliminates the beneficial conversion and cash conversion accounting models that require separate accounting for embedded conversion features and the recognition of a debt discount and related amortization to interest expense of those embedded features.

The Company elected to early adopt this standard effective January 1, 2021 using the modified retrospective approach transition method. Therefore, the consolidated financial statements for the years ended December 31, 2023, 2022 and 2021 are presented under the new standard.

In connection with the adoption of this standard, the Company recognized a cumulative effect adjustment, net of tax, of $6.1 million to retained earnings on the Company's consolidated balance sheet as of January 1, 2021. This adjustment was primarily driven by the derecognition of interest expense related to the accretion of the debt discount associated with the embedded conversion option recorded in the prior period as required under the legacy guidance. In addition, the Company reclassified $75.6 million, less related tax of $17.1 million and issuance costs of $2.9 million, from additional paid-in-capital ("APIC") to long-term debt and finance leases on the Company's consolidated balance sheet as of January 1, 2021. The reclassification was recorded in order to combine the two legacy units of account into a single instrument classified as a liability since bifurcation of the instrument into two units of account is no longer required under this standard.

14.Leases

The Company leases aircraft, engines, airport terminals, maintenance and training facilities, aircraft hangars, commercial real estate and office and computer equipment, among other items. Certain of these leases include provisions for variable lease payments which are based on several factors, including, but not limited to, relative leases square footage, enplaned passengers, and airports' annual operating budgets. Due to the variable nature of the rates, these leases are not recorded on the Company's consolidated balance sheets as a right-of-use asset and lease liability. Lease terms are generally 4 to 18 years for aircraft and up to 99 years for other leased equipment and property.

As of December 31, 2023, the Company had a fleet consisting of 205 A320 family aircraft. As of December 31, 2023, the Company had 117 aircraft financed under operating leases with lease term expirations between 2025 and 2041. In addition, the Company owned 73 aircraft of which, as of December 31, 2023, 17 were unencumbered. The Company also had 15 aircraft that would have been deemed finance leases resulting in failed sale-leaseback transactions. The related finance obligation is recorded within long-term debt in the Company's consolidated balance sheets. Refer to Note 13, Debt and Other Obligations for additional information. The related asset is recorded within flight equipment in the Company's consolidated balance sheets. As of December 31, 2023, the Company also had 6 spare engines financed under operating leases with lease term expiration dates ranging from 2024 to 2033 and owned 28, of which, as of December 31, 2023, 4 were unencumbered and 24 were pledged as collateral under the Company's revolving credit facility maturing in 2025.

Total rent expense for the years ended 2023, 2022 and 2021 was $673.2 million, $537.9 million and $449.4 million, respectively. Total rental expense for aircraft and engine operating leases for the years ended December 31, 2023, 2022 and 2021 was $381.2 million, $282.4 million and $246.6 million, respectively.

Under the terms of the lease agreements, the Company will continue to operate and maintain the aircraft. Payments under the majority of the lease agreements are fixed for the term of the lease. The lease agreements contain standard termination events, including termination upon a breach of the Company's obligations to make rental payments and upon any other material breach of the Company's obligations under the leases, and standard maintenance and return condition provisions. These return provisions are evaluated at inception of the lease and throughout the lease terms and are accounted for as either fixed or variable lease payments (depending on the nature of the lease return condition) when it is probable that such amounts will be incurred. When determining probability and estimated cost of lease return obligations, there are various other factors that need to be considered such as the contractual terms of the lease, the ability to swap engines or other aircraft components, current condition of the aircraft, the age of the aircraft at lease expiration, utilization of engines and other components, the extent of repairs needed at return, return locations, current configuration of the aircraft and cost of repairs and materials at the time of return. Management assesses the factors listed above and the need to accrue lease return costs throughout the lease as facts and circumstances warrant an assessment. The Company expects lease return costs will increase as individual aircraft lease agreements approach their respective termination dates and the Company begins to accrue the estimated cost of return conditions for the corresponding aircraft. Upon a termination of the lease due to a breach by the Company, the Company would be liable for standard contractual damages, possibly including damages suffered by the lessor in connection with remarketing the aircraft or while the aircraft is not leased to another party.

Aircraft rent expense consists of monthly lease rents for aircraft and spare engines under the terms of the Company's aircraft and spare engine lease agreements recognized on a straight-line basis. Supplemental rent, recorded within aircraft rent expense, is primarily made up of probable and estimable return condition obligations, lease return costs adjustments for aircraft and engines purchased off lease or lease extensions or amendments. The Company expensed $14.0 million, $16.5 million and $31.7 million of supplemental rent recorded within aircraft rent during 2023, 2022 and 2021, respectively.

Notes to Financial Statements—(Continued)

During the fourth quarter of 2019, the Company purchased an 8.5-acre parcel of land for $41.0 million and entered into a 99-year lease agreement for the lease of a 2.6-acre parcel of land, in Dania Beach, Florida, where the Company is building its new headquarters campus and a 200-unit residential building. During the first quarter of 2022, the Company began building its new headquarters campus and its 200-unit residential building with an expected completion during the first quarter of 2024. As of December 31, 2023, the 8.5-acre parcel of land and $184.6 million in related construction costs were capitalized within ground property and equipment on the Company's consolidated balance sheets. The 99-year lease was determined to be an operating lease and is recorded within operating lease right-of-use asset and operating lease liability on the Company's consolidated balance sheets. Operating lease commitments related to this lease are included in the table below within property facility leases.

The following table provides details of the Company's future minimum lease payments under finance lease liabilities and operating lease liabilities recorded on the Company's consolidated balance sheets as of December 31, 2023. The table does not include commitments that are contingent on events or other factors that are currently uncertain and unknown.

15. Defined Contribution 401(k) Plan

The Company sponsors three defined contribution 401(k) plans, Spirit Airlines, Inc. Employee Retirement Savings Plan (first plan), Spirit Airlines, Inc. Pilots’ Retirement Savings Plan (second plan) and Spirit Airlines, Inc. Puerto Rico Retirement Savings Plan (third plan). The first plan is for all employees that are not covered by the pilots’ collective bargaining agreement, who have at least 60 days of service and have attained the age of 21.

The second plan is for the Company’s pilots, and contains the same service requirements as the first plan. Beginning on March 1, 2018, the Company contributed 11% of the individual pilot's annual compensation, regardless of the pilot's contributions to the plan. The Company's contribution increased by 1% on an annual basis each March until 2022, at which time the contribution was 15%. Beginning on January 1, 2024, the Company's contribution increased to 16%.

Employer contributions made to all plans were $112.4 million, $88.9 million and $72.3 million in 2023, 2022 and 2021, respectively, and were included within salaries, wages and benefits in the accompanying consolidated statements of operations.

Total income tax expense (benefit)	19.9	%	20.9	%	9.2	%

The Company accounts for income taxes using the asset and liability method. Deferred taxes are recorded based on differences between the consolidated financial statement basis and tax basis of assets and liabilities and available tax loss and credit carryforwards. At December 31, 2023 and 2022, the significant components of the Company's deferred taxes consisted of the following:

	December 31,
	2023		2022
	(in thousands)
Deferred tax assets:
Income tax credits	$	4,298	$	4,306
Net operating losses	328,977		340,023
Deferred revenue	25,924		20,751
Nondeductible accruals	32,899		25,738
Deferred manufacturing credits	14,556		14,054
Loan liability	115,161		11,404
Operating lease liability	797,778		598,097
Interest expense	51,305		38,327
Other	38,910		27,190
Valuation allowance	(17,654)		(10,852)
Deferred tax assets	1,392,154		$	1,069,038
Deferred tax liabilities:
Property, plant and equipment	612,571		634,018
Accrued aircraft and engine maintenance	70,997		38,755
Right-of-use asset	803,232		608,176
Other	13,115		14,932
Deferred tax liabilities	1,499,915		1,295,881
Net deferred tax assets (liabilities)	$	(107,761)	$	(226,843)

In assessing the realizability of the deferred tax assets, management considered whether it is more likely than not that some or all of the deferred tax assets would be realized. In evaluating the Company’s ability to utilize its deferred tax assets, it considered all available evidence, both positive and negative, in determining future taxable income on a jurisdiction by jurisdiction basis. As of December 31, 2023 and 2022, the Company had a valuation allowance of $17.7 million and $10.9 million, respectively, against certain deferred tax assets related to equity compensation for executives due to changes in tax law resulting from the Tax Cuts and Jobs Act ("TCJA"), state net operating loss carryforwards and foreign tax credits.

As of December 31, 2023, the Company had $2.8 million of foreign tax credits, $1.4 million of general business tax credits, $1.4 billion of federal net operating loss and $643.5 million of state net operating loss available, that may be applied against future tax liabilities. The foreign tax credits will begin to expire in 2025, the state net operating losses will begin to expire in 2027, the general business credits will begin to expire in 2038 and there is no expiration of federal net operating losses.

101

Notes to Financial Statements—(Continued)

For tax years ended December 31, 2023, 2022 and 2021, the Company did not recognize any liabilities for uncertain tax positions nor any interest and penalties on unrecognized tax benefits.

For tax years 2023, 2022 and 2021, all income for the Company is subject to domestic income taxes.

The Company files its tax returns as prescribed by the tax laws of the jurisdictions in which it operates. The Company's federal income tax returns for 2020 through 2022 tax years are still subject to examination in the United States Various state and foreign jurisdiction tax years also remain open to examination. The Company believes that any potential assessment would be immaterial to its consolidated financial statements.

17. Commitments and Contingencies

Aircraft-Related Commitments and Financing Arrangements

The Company’s contractual purchase commitments consist primarily of aircraft and engine acquisitions through manufacturers and aircraft leasing companies. As of December 31, 2023, the Company's firm aircraft orders consisted of 99 A320 family aircraft with Airbus, including A320neos and A321neos, with deliveries expected through 2029. On July 31, 2023, the Company entered into Amendment No. 6 (the “Amendment”) to the A320 NEO Family Purchase Agreement, dated as of December 20, 2019 (the “Airbus Purchase Agreement”) with Airbus S.A.S. (“Airbus”). The Amendment converts the remaining A319neo aircraft to be delivered under the Airbus Purchase Agreement to A321neo aircraft. The Amendment also (i) defers certain A320neo aircraft deliveries from 2024 to 2025 and later years, (ii) extends delivery dates for certain A320neo and A321neo aircraft deliveries from 2025-2027 to 2025-2029 and (iii) adjusts the timing of option aircraft delivery dates from 2026-2028 to 2027-2029. In addition, the Amendment creates a more equal distribution of aircraft deliveries and option rights across the delivery periods. As of December 31, 2023, the Company had secured financing for 18 aircraft, scheduled for delivery from Airbus through 2025, which will be financed through sale-leaseback transactions. The Company did not have financing commitments in place for the remaining 81 Airbus aircraft currently on firm order, which are scheduled for delivery through 2029. However, the Company has signed a financing letter of agreement with Airbus which provides backstop financing for a majority of the aircraft included in the A320 NEO Family Purchase Agreement. The agreement provides a standby credit facility in the form of senior secured mortgage debt financing. The contractual purchase amounts for these aircraft are included within the purchase commitments below.

During the third quarter of 2021, the Company entered into an Engine Purchase Support Agreement which requires the Company to purchase a certain number of spare engines in order to maintain a contractual ratio of spare engines to aircraft in the fleet. As of December 31, 2023, the Company is committed to purchase 19 PW1100G-JM spare engines, with deliveries through 2029.

As of December 31, 2023, committed expenditures for these aircraft and spare engines, including estimated amounts for contractual price escalations and pre-delivery payments, are expected to be $507.6 million in 2024, $1,018.6 million in 2025, $1,034.3 million in 2026, $1,100.0 million in 2027, $1,035.2 million in 2028, and $923.8 million in 2029 and beyond.

During the third quarter of 2019, the United States announced its decision to levy tariffs on certain imports from the European Union, including commercial aircraft and related parts. These tariffs include aircraft and other parts that the Company is already contractually obligated to purchase including those reflected above. In June 2021, the United States Trade Representative announced that the United States and European Union had agreed to suspend reciprocal tariffs on large civilian aircraft for five years, pending discussions to resolve their trade dispute. For further discussion on this topic, please refer to "Risk Factors - Risks Related to Our Business - Any tariffs imposed on commercial aircraft and related parts imported from outside the United States may have a material adverse effect on our fleet, business, financial condition and our results of operations."

In addition to the aircraft purchase agreement, as of December 31, 2023, the Company had secured financing for 22 aircraft to be leased directly from third-party lessors, scheduled for delivery through 2025. As of December 31, 2023, aircraft rent commitments for future aircraft deliveries to be financed under direct leases from third-party lessors and sale-leaseback transactions are expected to be approximately $72.4 million in 2024, $167.8 million in 2025, $183.3 million in 2026, $183.3 million in 2027, $183.3 million in 2028, and $1,409.3 million in 2029 and beyond.

Interest commitments related to the secured debt financing of 71 aircraft as of December 31, 2023 are $80.2 million in 2024, $73.6 million in 2025, $67.3 million in 2026, $60.2 million in 2027, $51.7 million in 2028, and $204.5 million in 2029 and beyond. As of December 31, 2023, interest commitments related to the Company's 8.00% senior secured notes, convertible debt financing, unsecured term loans and revolving credit facility are $96.7 million in 2024, $89.4 million in 2025, $5.9 million in 2026, $3.4 million in 2027, $3.4 million in 2028, and $7.1 million in 2029 and beyond. For principal commitments related to the Company's outstanding debt obligations, refer to Note 13, Debt and Other Obligations.

102

Notes to Financial Statements—(Continued)

The Company is contractually obligated to pay the following minimum guaranteed payments for its reservation system, construction commitments related to its new headquarters campus and residential building and other miscellaneous subscriptions and services as of December 31, 2023: $65.0 million in 2024, $27.5 million in 2025, $18.1 million in 2026, $18.0 million in 2027, $1.9 million in 2028, and none in 2029 and beyond. During the first quarter of 2018, the Company entered into a contract renewal with its reservation system provider which expires in 2028.

Litigation

The Company is subject to commercial litigation claims and to administrative and regulatory proceedings and reviews that may be asserted or maintained from time to time. The Company believes the ultimate outcome of such lawsuits, proceedings and reviews will not, individually or in the aggregate, have a material adverse effect on its financial position, liquidity or results of operations. In making a determination regarding accruals, using available information, the Company evaluates the likelihood of an unfavorable outcome in legal or regulatory proceedings and assessments to which the Company is a party and records a loss contingency when it is probable a liability has been incurred and the amount of the loss can be reasonably estimated. These subjective determinations are based on the status of such legal or regulatory proceedings, the merits of the Company's defenses, and consultation with legal counsel. Actual outcomes of these legal and regulatory proceedings may materially differ from the Company's current estimates. It is possible that resolution of one or more of the legal matters currently pending or threatened could result in losses material to the Company's consolidated results of operations, liquidity, or financial condition.

In 2017, the Company was sued in the Eastern District of New York ("EDNY") in a purported class action, Cox, et al. v. Spirit Airlines, Inc., alleging state-law claims of breach of contract, unjust enrichment and fraud relating to the Company's practice of charging fees for ancillary products and services. The original action was dismissed by the EDNY; however, following the plaintiff's appeal to the Second Circuit, the case was remanded to the EDNY for further review on the breach of contract claim. A hearing on the Company's Motion for Summary Judgment and plaintiff's Motion for Class Certification was held on December 10, 2021. The EDNY granted the plaintiff's class certification motion and denied Spirit’s summary judgment motion on March 29, 2022. The Company subsequently filed a motion for reconsideration on April 26, 2022, and an oral argument was held on May 19, 2022. The EDNY denied Spirit’s motion for reconsideration on February 14, 2023. On April 3, 2023, Spirit moved to compel arbitration of and/or dismiss certain class members’ claims for lack of personal jurisdiction. Trial was set to begin on January 16, 2024. In June 2023, the Company reached a tentative settlement in mediation for a maximum amount of $8.3 million. The EDNY issued a preliminary approval order on September 21, 2023, and the final approval hearing was held on December 11, 2023. The total amount paid depends on a number of factors, including participation of class members and any conditions on the settlement approved by the EDNY. Currently, the Company's best estimate of the probable loss associated with the settlement is $6.0 million, and the Company has recorded this amount in other operating expenses within its consolidated statements of operations.

On February 27, 2023, ALPA filed a grievance against the Company claiming that it violated the collective bargaining agreement (“CBA”) by excluding its pilots from the Company's retention award programs granted as part of the Former Frontier Merger Agreement and the Merger Agreement with JetBlue. On September 8, 2023, the Company filed a motion to dismiss the grievance, as it does not believe that ALPA filed the grievance within the timeline set forth in the CBA. As of December 31, 2023, the potential outcomes of this claim cannot be determined and an estimate of the reasonably possible loss or range of loss cannot be made.

Following an audit by the Internal Revenue Service ("IRS") related to the collection of federal excise taxes on optional passenger seat selection charges covering the period of the second quarter 2018 through the fourth quarter 2020, on March 31, 2022, the Company was assessed $34.9 million. On July 19, 2022, the assessment was reduced to $27.5 million. The Company believes a loss in this matter is not probable and has not recognized a loss contingency.

(1) Subject to standard early opener provisions.

(2) Collective bargaining agreement is currently under negotiation.

During the fourth quarter of 2022, the Company reached an agreement with ALPA for a new two-year agreement, which was ratified by ALPA members on January 10, 2023. The ratified agreement includes increased pay rates and other enhanced benefits.

In February 2023, the Company and AFA-CWA reached an agreement with the Company's flight attendants which was ratified by the flight attendants on April 13, 2023 and becomes amendable in January 2026. The ratified agreement includes increased pay rates and other enhanced benefits.

In August 2022, the Company's aircraft maintenance technicians ("AMTs") voted to be represented by the Aircraft Mechanics Fraternal Association ("AMFA") as their collective bargaining agent. As of December 31, 2023, the Company employed approximately 700 AMTs. In November 2022, AMFA notified the Company of its intent to negotiate a CBA and began negotiations. In October 2023, AMFA filed for mediation with the National Mediation Board (“NMB”). The Company is currently waiting for mediation dates from the NMB to continue negotiating with AMFA.

In May 2023, PAFCA provided notice to the Company that it intends to amend its Collective Bargaining Agreement with its dispatchers. The parties began negotiating changes to the CBA on July 12, 2023. As of December 31, 2023, the Company continued to negotiate with PAFCA.

The Company is self-insured for health care claims, subject to a stop-loss policy, for eligible participating employees and qualified dependent medical claims, subject to deductibles and limitations. The Company’s liabilities for claims incurred but not reported are determined based on an estimate of the ultimate aggregate liability for claims incurred. The estimate is calculated from actual claim rates and adjusted periodically as necessary. The Company has accrued $9.1 million and $11.0 million, for health care claims as of December 31, 2023, and 2022, respectively, recorded within other current liabilities on the Company's consolidated balance sheet.

18.Fair Value Measurements

Under ASC 820, Fair Value Measurements and Disclosures, disclosures relating to how fair value is determined for assets and liabilities are required, and a hierarchy for which these assets and liabilities must be grouped is established, based on significant levels of inputs, as follows:

Level 1—Quoted prices in active markets for identical assets or liabilities.

Level 2—Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

104

Notes to Financial Statements—(Continued)

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company utilizes several valuation techniques in order to assess the fair value of the Company’s financial assets and liabilities.

Long-term Debt

    The estimated fair value of the Company's secured notes, term loan debt agreements and revolving credit facilities has been determined to be Level 3 as certain inputs used to determine the fair value of these agreements are unobservable. The Company utilizes a discounted cash flow method to estimate the fair value of the Level 3 long-term debt. The estimated fair value of the Company's publicly and non-publicly held EETC debt agreements and the Company's convertible notes has been determined to be Level 2 as the Company utilizes quoted market prices in markets with low trading volumes to estimate the fair value of its Level 2 long-term debt.

    The carrying amounts and estimated fair values of the Company's long-term debt at December 31, 2023 and December 31, 2022, were as follows:

	As of December 31,
	2023				2022
	Carrying Value		Estimated Fair Value		Carrying Value		Estimated Fair Value		Fair value level hierarchy
	(in millions)
8.00% senior secured notes	$	1,110.0	$	1,121.9	$	1,110.0	$	1,085.0	Level 3

Total long-term debt	$	3,439.1	$	3,253.5	$	3,642.4	$	3,355.0

Cash and Cash Equivalents

Cash and cash equivalents at December 31, 2023 and December 31, 2022 are comprised of liquid money market funds and cash and are categorized as Level 1 instruments. The Company maintains cash with various high-quality financial institutions.

Restricted Cash

Restricted cash is comprised of cash held in account subject to account control agreements or otherwise pledged as collateral against the Company's letters of credit and is categorized as a Level 1 instrument. As of December 31, 2023, the Company had a $85.0 million standby letter of credit secured by $75.0 million of restricted cash, of which $55.9 million were issued letters of credit. In addition, the Company had $44.4 million of restricted cash held in accounts subject to control agreements to be used for the payment of interest and fees on the Company's 8.00% senior secured notes. For additional information on the Company's 8.00% senior secured notes, refer to Note 13, Debt and Other Obligations.

Short-term Investment Securities

Short-term investment securities at December 31, 2023 and December 31, 2022 are classified as available-for-sale and generally consist of U.S. Treasury and U.S. government agency securities with contractual maturities of twelve months or less.

105

Notes to Financial Statements—(Continued)

The Company's short-term investment securities are categorized as Level 1 instruments, as the Company uses quoted market prices in active markets when determining the fair value of these securities. For additional information, refer to Note 8, Short-term Investment Securities.

Derivative Liability

The Merger Agreement with JetBlue modified the settlement terms for any conversions of the convertible notes due 2026 (as defined below) that caused the conversion option, which is an embedded derivative, not to qualify for the derivative accounting scope exception provided under ASC 815. As such, the Company bifurcated the fair value of the conversion option of the convertible notes due 2026 as a derivative liability with subsequent changes in fair value recorded in earnings.

The Company records the fair value of the embedded derivative as a derivative liability within deferred gains and other long-term liabilities on its consolidated balance sheets. The fair value of the derivative liability was estimated as the difference in value of the traded price of the convertible notes, including the conversion option and the value of the convertible notes in the absence of the conversion option (the debt component). The value of the debt component was estimated using a discounted cash flow analysis with a yield calibrated to the traded price of the convertible notes. The change in fair value of the derivative liability is recorded within interest expense on the Company's consolidated statements of operations and is included in other liabilities within operating activities in the Company's consolidated statements of cash flows. During the twelve months ended December 31, 2023 and 2022, the Company recorded $18.1 million and $20.3 million, respectively, in a favorable mark to market adjustment, related to the change in fair value of the derivative liability. The fair value of the derivative liability has been determined to be Level 2 as observable inputs were used to determine the fair value of derivative liability. For additional information, refer to Note 13, Debt and Other Obligations.

Assets and liabilities measured at gross fair value on a recurring basis are summarized below:

The Company attributes operating revenues by geographic region based upon the origin and destination of each passenger flight segment. The Company’s tangible assets consist primarily of flight equipment, which are mobile across geographic markets and, therefore, have not been allocated.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Directors of Spirit Airlines, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Spirit Airlines, Inc. (the Company) as of December 31, 2023 and 2022, the related consolidated statements of operations, comprehensive income (loss), shareholders' equity and cash flows for each of the three years in the period ended December 31, 2023, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated February 9, 2024 expressed an unqualified opinion thereon.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

108

Notes to Financial Statements—(Continued)

Description of the Matter

As explained in Notes 1 and 14 to the financial statements, the Company’s lease agreements often contain provisions that require the Company to return aircraft airframes, engines and other aircraft components to the lessor in a certain condition or pay an amount to the lessor based on the actual return condition. Management assesses the need to accrue lease return costs throughout the year or whenever facts and circumstances warrant an assessment. For the year ended December 31, 2023, the Company recorded $14 million of supplemental rent, which is made up of probable and estimable lease return costs. Auditing the estimate of lease return costs for engines was complex because of the significant judgment involved in determining the timing of future maintenance events.

How We Addressed the Matter in Our Audit

We obtained an understanding, evaluated the design and tested the operating effectiveness of the Company’s controls that address the risks of material misstatement relating to the measurement of lease return costs. For example, we tested controls over management’s review of the estimated timing of future maintenance events. To test the estimate of lease return costs, our audit procedures included, among others, testing the assumptions used and the accuracy and completeness of the underlying data used in the calculations. For example, to test the assumptions related to the timing of future maintenance events, we compared projected event timing to the time interval between recently completed maintenance events, regulatory requirements for aircraft and engine maintenance, current and projected utilization metrics for the aircraft, and changes to the fleet plan, including the anticipated effect of the accelerated inspections required due to manufacturing defects in engines. We also tested the historical accuracy of management’s forecasts of maintenance events by comparing when recent maintenance events occurred to management’s initial projections.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Directors of Spirit Airlines, Inc.

Opinion on Internal Control Over Financial Reporting

We have audited Spirit Airlines, Inc.’s internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Spirit Airlines, Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2023 and 2022, the related consolidated statements of operations, comprehensive income (loss), shareholders' equity and cash flows for each of the three years in the period ended December 31, 2023, and the related notes and our report dated February 9, 2024 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management's Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

None.

ITEM 9A.    CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Management, with the participation of our Chief Executive Officer and our Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2023. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to our management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure.

Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of December 31, 2023, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Management's Annual Report on Internal Control Over Financial Reporting

Evaluation of Disclosure Controls and Procedures

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies may deteriorate.

Management conducted an evaluation of the effectiveness of our internal control over financial reporting based on the 2013 framework established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO Framework). Based on that evaluation, management believes that our internal control over financial reporting was effective as of December 31, 2023.

The effectiveness of our internal control over financial reporting as of December 31, 2023 has been audited by Ernst & Young LLP, an independent registered public accounting firm, which also audited our Consolidated Financial Statements for the year ended December 31, 2023. Ernst & Young LLP's report on our internal control over financial reporting is included herein.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

ITEM 9B.    OTHER INFORMATION

Exhibit 4.67

BRIEF DESCRIPTION OF ALL SECURITIES REGISTERED UNDER SECTION 12 OF THE EXCHANGE ACT

General

As of February 1, 2024, there were 111,602,429 shares of our voting common stock issued, 109,477,999 shares of our voting common stock outstanding and no shares of our non-voting common stock issued and outstanding.

Our amended and restated certificate of incorporation authorizes us to issue up to 240,000,000 shares of voting common stock, $0.0001 par value per share, 50,000,000 shares of non-voting common stock, $0.0001 par value per share, and 10,000,000 shares of preferred stock, $0.0001 par value per share. All of our issued and outstanding shares of common stock and preferred stock, if any, are duly authorized, validly issued, fully paid and non-assessable. Our shares of voting common stock and non-voting common stock are not redeemable and do not have preemptive rights.

The remaining shares of authorized and unissued capital stock are available for future issuance, subject to our amended and restated certificate of incorporation, amended and restated bylaws and applicable law, including any regulations governing the exchange on which our shares of capital stock are then listed. While the additional shares are not designed to deter or prevent a change of control, under some circumstances we could use the additional shares to create voting impediments or to frustrate persons seeking to effect a takeover or otherwise gain control by, for example, issuing those shares in private placements to purchasers who might side with our board of directors in opposing a hostile takeover bid.

The following description of our capital stock and provisions of our amended and restated certificate of incorporation and amended and restated bylaws summarize the material terms and provisions of our capital stock. Such descriptions are qualified by reference to the amended and restated certificate of incorporation and the amended and restated bylaws, copies of which have been filed with the Securities and Exchange Commission (the “SEC”).

Voting Common Stock

Dividend Rights. Holders of our voting common stock are entitled to receive dividends, if any, as may be declared from time to time by our board of directors out of legally available funds ratably with shares of our non-voting common stock, subject to preferences that may be applicable to any then outstanding preferred stock and limitations under the Delaware General Corporation Law.

Voting Rights. Each holder of our voting common stock is entitled to one vote for each share on all matters submitted to a vote of the stockholders, including the election of directors. Our

stockholders do not have cumulative voting rights in the election of directors. Accordingly, holders of a majority of the voting shares are able to elect all of the directors properly up for election at any given stockholders’ meeting.

Liquidation. In the event of our liquidation, dissolution or winding up, holders of our voting common stock will be entitled to share ratably with shares of our non-voting common stock in the net assets legally available for distribution to stockholders after the payment of all of our debts and other liabilities and the satisfaction of any liquidation preference granted to the holders of any then outstanding shares of preferred stock.

Rights and Preferences. Holders of our voting common stock have no preemptive, conversion, subscription or other rights, and there are no redemption or sinking fund provisions applicable to our voting common stock. The rights, preferences and privileges of the holders of our voting common stock are subject to and may be adversely affected by, the rights of the holders of shares of any series of our preferred stock that we may designate in the future.

Non-Voting Common Stock

Dividend Rights. Holders of our non-voting common stock are entitled to receive dividends, if any, as may be declared from time to time by our board of directors out of legally available funds ratably with shares of our voting common stock, subject to preferences that may be applicable to any then outstanding preferred stock and limitations under the Delaware General Corporation Law.

Voting Rights. Shares of our non-voting common stock are not entitled to vote on any matters submitted to a vote of the stockholders, including the election of directors, except to the extent required under the Delaware General Corporation Law.

Conversion Rights. Shares of our non-voting common stock are convertible on a share-for-share basis into voting common stock at the election of the holder. Please see “—Limited Voting by Foreign Owners.”

Liquidation. In the event of our liquidation, dissolution or winding up, holders of our non-voting common stock will be entitled to share ratably with shares of our voting common stock in the net assets legally available for distribution to stockholders after the payment of all of our debts and other liabilities and the satisfaction of any liquidation preference granted to the holders of any then outstanding shares of preferred stock.

Rights and Preferences. Holders of our non-voting common stock have no preemptive, subscription or other rights, and there are no redemption or sinking fund provisions applicable to our non-voting common stock. The rights, preferences and privileges of the holders of our non-

voting common stock are subject to and may be adversely affected by, the rights of the holders of shares of any series of our preferred stock that we may designate in the future.

Preferred Stock

Under our amended and restated certificate of incorporation, our board of directors has the authority, without further action by our stockholders, to issue up to 10,000,000 shares of preferred stock, par value $0.0001 per share, in one or more series and to fix the rights, preferences, privileges and restrictions thereof. These rights, preferences and privileges could include dividend rights, conversion rights, voting rights, terms of redemption, liquidation preferences, sinking fund terms and the number of shares constituting any series or the designation of such series, any or all of which may be greater than the rights of common stock. Our issuance of preferred stock could adversely affect the voting power of holders of common stock and the likelihood that such holders will receive dividend payments and payments upon liquidation. In addition, the issuance of preferred stock could have the effect of delaying, deferring or preventing a change of control of our company or other corporate action.

Anti-Takeover Provisions of Our Certificate of Incorporation and Bylaws

Our amended and restated certificate of incorporation provides for our board of directors to be divided into three classes, with staggered three-year terms. Only one class of directors will be elected at each annual meeting of our stockholders, with the other classes continuing for the remainder of their respective three-year terms. Because our stockholders do not have cumulative voting rights, our stockholders holding a majority of the shares of voting common stock outstanding will be able to elect all of our directors up for election at any given stockholders’ meeting. At any given stockholders’ meeting for the election of directors at which a quorum is present, a plurality of the votes cast shall be sufficient to elect a director up for election. Except as otherwise required by applicable law or the rights and preferences of any then-outstanding preferred stock, our amended and restated certificate of incorporation and amended and restated bylaws provide that a director may be removed from the board of directors with cause by a majority vote of the shares of voting common stock outstanding, but vacancies may only be filled by the board of directors. Our amended and restated certificate of incorporation and amended and restated bylaws provide that all stockholder action must be effected at a duly called meeting of stockholders and not by a consent in writing, and that only our corporate secretary, upon the direction of our board of directors, or the Chairman of the Board may call a special meeting of stockholders. Our amended and restated bylaws also establish advance notice procedures with regard to all stockholder proposals to be brought before meetings of our stockholders, including proposals for the nomination of candidates for election as directors, all of which must be brought in a timely manner. Timely, for purposes of our amended and restated bylaws, generally means delivery of notice to us not less than 90 days nor more than 120 days prior to the first anniversary of the prior year’s annual meeting date.

Our amended and restated certificate of incorporation and amended and restated bylaws requires a 66 2/3% stockholder vote for the amendment, repeal or modification of certain provisions of our amended and restated certificate of incorporation and amended and restated bylaws including, among other things, relating to the classification of our board of directors, the requirement that stockholder actions be effected at a duly called meeting, and the designated parties entitled to call a special meeting of the stockholders. The combination of the classification of our board of directors, the lack of cumulative voting and the 66 2/3% stockholder voting requirements make it more difficult for our stockholders to replace our board of directors as well as for another party to obtain control of us by replacing our board of directors. Because our board of directors has the power to retain and discharge our officers, these provisions could also make it more difficult for stockholders or another party to effect a change in management. In addition, the authorization of undesignated preferred stock makes it possible for our board of directors to issue preferred stock with voting or other rights or preferences that could impede the success of any attempt to change our control.

These provisions may have the effect of deterring hostile takeovers or delaying changes in our control or management. These provisions are intended to enhance the likelihood of continued stability in the composition of our board of directors and its policies and to discourage certain types of transactions that may involve an actual or threatened acquisition of us. These provisions are designed to reduce our vulnerability to an unsolicited acquisition proposal. The provisions also are intended to discourage certain tactics that may be used in proxy fights. However, such provisions could have the effect of discouraging others from making tender offers for our shares and, as a consequence, they also may inhibit fluctuations in the market price of our shares that could result from actual or rumored takeover attempts. Such provisions may also have the effect of preventing changes in our management.

Section 203 of the Delaware General Corporation Law. We are subject to Section 203 of the Delaware General Corporation Law, which prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years after the date that such stockholder became an interested stockholder, with the following exceptions:

•before such date, the board of directors of the corporation approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder;

•upon completion of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction began, excluding for purposes of determining the voting stock outstanding (but not the outstanding voting stock owned by the interested stockholder) those shares owned (i) by

persons who are directors and also officers and (ii) employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or

•on or after such date, the business combination is approved by the board of directors and authorized at an annual or special meeting of the stockholders, and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding voting stock that is not owned by the interested stockholder.

In general, Section 203 defines business combination to include the following:

•any merger or consolidation involving (i) the corporation or any majority-owned subsidiary of the corporation and (ii) the interested stockholder or any other corporation, partnership, unincorporated association or other entity if the merger or consolidation is caused by the interested stockholder;

•any sale, lease, exchange, mortgage, pledge, transfer or other disposition of 10% or more of the assets of the corporation involving the interested stockholder;

•subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation or by any majority-owned subsidiary of the corporation of any stock of the corporation to the interested stockholder;

•any transaction involving the corporation or any majority-owned subsidiary of the corporation that has the effect of increasing the proportionate share of the stock or any class or series, or securities convertible into the stock of any class or series, of the corporation, or of any such subsidiary, beneficially owned by the interested stockholder; or

•the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or through the corporation or any majority-owned subsidiary.

In general, Section 203 defines an “interested stockholder” as an entity or person who, together with the person’s affiliates and associates, beneficially owns, or within three years prior to the time of determination of interested stockholder status did own, 15% or more of the outstanding voting stock of the corporation.

Limited Voting by Foreign Owners

To comply with restrictions imposed by federal law on foreign ownership of U.S. airlines, our amended and restated certificate of incorporation and amended and restated bylaws restrict voting of shares of our capital stock by non-U.S. citizens. The restrictions imposed by federal law currently require that no more than 25% of our voting stock be voted, directly or indirectly, by persons who are not U.S. citizens, and that our president and at least two-thirds of the members of our board of directors and senior management be U.S. citizens. Our amended and restated bylaws provide that no shares of our capital stock may be voted by or at the direction of non-U.S. citizens unless such shares are registered on a separate stock record, which we refer to as the foreign stock record. Our amended and restated bylaws further provide that no shares of our capital stock will be registered on the foreign stock record if the amount so registered would exceed the foreign ownership restrictions imposed by federal law.

Delaware as Sole and Exclusive Forum

Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware shall be the sole and exclusive forum for (a) any derivative action or proceeding brought on behalf of us, (b) any action asserting a claim of breach of a fiduciary duty owed by any of our directors or officers to us or our stockholders, (c) any action asserting a claim against us arising pursuant to any provision of the Delaware General Corporation Law or our amended and restated certificate of incorporation or amended and restated bylaws or (d) any action asserting a claim against us governed by the internal affairs doctrine. As a result, any action brought by any of our stockholders with regard to any of these matters will need to be filed in the Court of Chancery of the State of Delaware and cannot be filed in any other jurisdiction.

Limitations of Liability and Indemnification

Our amended and restated certificate of incorporation contains provisions that limit the liability of our directors for monetary damages to the fullest extent permitted by the Delaware General Corporation Law. Consequently, our directors will not be personally liable to us or our stockholders for monetary damages for any breach of fiduciary duties as directors, except liability for:

•any breach of the director’s duty of loyalty to us or our stockholders;

•any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;

•unlawful payments of dividends or unlawful stock repurchases or redemptions as provided in Section 174 of the Delaware General Corporation Law; or

•any transaction from which the director derived an improper personal benefit.

Our amended and restated certificate of incorporation provides that we may indemnify our directors and officers, in each case to the fullest extent permitted by the Delaware General Corporation Law. Our amended and restated bylaws also provide that we are obligated to indemnify our directors and officers to the fullest extent permitted by the Delaware General Corporation Law and advance expenses incurred by a director or officer in advance of the final disposition of any action or proceeding, and they permit us to secure insurance on behalf of any officer, director, employee or other agent for any liability arising out of his or her actions in that capacity regardless of whether we would otherwise be permitted to indemnify him or her under the provisions of the Delaware General Corporation Law. We have entered into agreements to indemnify our directors, executive officers and other employees as determined by our board of directors. With specified exceptions, these agreements provide for indemnification for related expenses including, among other things, attorneys’ fees, judgments, fines and settlement amounts incurred by any of these individuals in any action or proceeding. We believe that these limitation of liability provisions and indemnification agreements are necessary to attract and retain qualified persons as directors and officers. We also maintain directors’ and officers’ liability insurance.

The limitation of liability and indemnification provisions in our amended and restated certificate of incorporation, amended and restated bylaws and indemnification agreements may discourage stockholders from bringing a lawsuit against our directors and officers for breach of their fiduciary duty.

Our amended and restated certificate of incorporation provides that any such lawsuit must be brought in the Court of Chancery of the State of Delaware. However, because the applicability of the exclusive forum provision is limited to the extent permitted by applicable law, we do not intend for the exclusive forum provision to apply to suits brought to enforce any duty or liability created by the Securities Exchange Act of 1934, as amended, or any other claim for which the federal courts have exclusive jurisdiction, and acknowledge that federal courts have concurrent jurisdiction over all suits brought to enforce any duty or liability created by the Securities Act. We note that there is uncertainty as to whether a court would enforce the provision as it applies to the Securities Act of 1933, as amended (the "Securities Act") and that stockholders cannot waive compliance with the federal securities laws and the rules and regulations thereunder. The foregoing provisions may also reduce the likelihood of derivative litigation against our directors and officers, even though an action, if successful, might benefit us and other stockholders.

Further, a stockholder’s investment may be adversely affected to the extent that we pay the costs of settlement and damage awards against directors and officers as required by these indemnification provisions. Insofar as indemnification for liabilities arising under the Securities

Act may be permitted to our directors, officers and controlling persons pursuant to the foregoing provisions, or otherwise, we have been advised that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act, and is, therefore, unenforceable. At present, there is no pending litigation or proceeding involving any of our directors, officers or employees for which indemnification is sought, and we are not aware of any threatened litigation that may result in claims for indemnification.

Market Listing

Our common stock is listed and traded on the New York Stock Exchange under the symbol “SAVE.”

If the Buyer experiences any technical problem in the operation of an Aircraft or its systems due to a malfunction, the cause of which, after due and reasonable investigation, is not readily identifiable by the Buyer but which the Buyer reasonably believes to be attributable to the design characteristics of one or more components of the Aircraft ("Interface Problem"), the Seller shall, if so requested by the Buyer,[***], promptly conduct or have conducted an investigation and analysis of such problem to determine, if possible, the cause or causes of the problem and to recommend such corrective action as may be feasible.

If the Seller determines, acting reasonably, that the Interface Problem is attributable partially to the design of a Warranted Part and partially to the design of any Supplier Part, the Seller shall, if so requested by the Buyer, seek a solution to the Interface Problem through cooperative efforts of the Seller and any Supplier involved.

The Seller shall promptly advise the Buyer of such corrective action as may be proposed by the Seller and any such Supplier. Such proposal shall be consistent with any then existing obligations of the Seller hereunder and of any such Supplier towards the Buyer.[***]

IAE shall, upon written request from Spirit and subject to the permission of the appropriate governmental authorities, arrange for Spirit to have reasonable access to the appropriate premises in order to examine the Spare Engines prior to the issue of conformance documentation and to witness Engine acceptance tests.

Page 7 of 7

Those parts which do not lend themselves to automatic control due to supercedure, unusual usage or conversion requirements are under the direct manual control of Spares Planning personnel. As additional protection against changes in production lead time or unpredicted demand, certain raw materials are also inventoried. Successful inventory management is keyed to accurate requirements planning. In support of the requirements planning effort, a wide ranging data retrieval and analysis program is offered. This program concerns itself both with the customer logistics and technical considerations as follows:

Page 45 of 45

• Forecasts of life limited parts requirements are requested and received semi-annually from major customers. Based on the size of Spirit's order, Spirit shall be considered a major customer.

• Engine technical conferences are held frequently within IAE to assess the impact of technical problems on parts.

• For a selected group of parts a provisioning conference system is offered which considers actual part inventory change, including usage and receipts, as reported monthly by participating customers.

5.1.5 Packaging

All material is packaged in general compliance with Air Transport Association of America (ATA) Specification No. 300.

5.1.6 World Airline Supplier's Guide:

IAE subscribes to the supply objectives set forth in the World Airlines Supplier's Guide published by the Air Transport Association of America (ATA). IAE requires that its proprietary component vendors also perform in compliance with the precepts of the World Airline Suppliers' Guide.

15.1 Excusable Delays

IAE shall not be charged with any liability for delay in the performance of any of its obligations when such delay is caused by acts of God or the public enemy, compliance in good faith with any applicable foreign or domestic governmental regulation or order whether or not it proves to be invalid, fires, riots, labor disputes, unusually severe weather, or any cause beyond the reasonable control of IAE, or by delays of IAE's suppliers for any of the same or similar causes. To the extent that such causes actually delay performance on the part of IAE, the time for the performance shall be extended for as many days as are required to obtain removal of such causes. This provision shall not, however, relieve IAE from using its

reasonable efforts to avoid or remove such causes and continue performance with reasonable dispatch whenever such causes are removed ("Excusable Delay").

If Spirit fails to comply with the requirements set forth in Section9, and such failure or non-approval, as applicable causes the Maintenance Center to reasonably reschedule or delay the induction or completion of a Shop Visit for an Eligible Engine, then such delay shall constitute an Excusable Delay for IAE.

16. Duplicate Benefits

Spirit and IAE agree that it is not the intention to provide duplicate benefits under the terms of this Agreement and the GTA or under any other arrangement between IAE or

IAE's suppliers or Airbus and Spirit. In the event of any such duplication of benefits, Spirit may, at the relevant time in respect of the relevant circumstances receive any one such benefit (at Spirit's discretion) to the exclusion of all duplicate benefits.

IAE will either settle such claim or pay all damages and costs awarded in a non-appealable judgment, excluding indirect, incidental, special, consequential, and punitive damages. If the use or resale of such goods or part(s) is finally enjoined, IAE will, at its option: (a) procure for Spirit the right to use or resell such goods or parts;(b) replace such goods or parts with equivalent non-infringing parts;(c) modify such goods or parts so they become non-infringing but equivalent; or(d) remove such goods or part(s) and refund the purchase price (less a reasonable allowance for use, damage or obsolescence).

17.2 The preceding provision is applicable only if the following conditions are met: (a) the goods, part(s), services, or process involved in the suit, claim, or action must have been provided under this Agreement during Maintenance Services in accordance with this Agreement, as applicable;(b) the alleged infringement must be an infringement of any patents of the nation in which Spirit's principal place of business is located or a jurisdiction within which the relevant Supplies were manufactured or delivered to Spirit;(c) Spirit must provide IAE with timely notice of such suit, claim, or action and the full opportunity to assume the entire defense thereof; and(d) Spirit must provide IAE with all information available to Spirit and other defendants pertaining to the alleged infringement.

Exhibit IFHA Rate Adjustment Tables

The FHA Rates have been calculated based on Spirit meeting the General Conditions detailed in Section 10.6 of the Agreement.

To the extent that any operating parameters vary, the applicable charges shall be generated from the rate change tables contained in this Exhibit I. In the event that Spirit's actual operating conditions fall between points in the FHA Rate Adjustment Matrices, IAE shall use the Microsoft Excel spreadsheets referenced in Exhibit I hereto to calculate the applicable FHA Rate using linear interpolation (the "FHA Rate Interpolation Tool"). If the actual utilization parameters fall between two separate tables, the table with the higher factor shall apply.

If any of the actual operating parameters fall outside the coverage of the tables contained in this Exhibit I, the Parties shall agree a rate adjustment based on the same method of calculation used to derive the tables (and not based on simple extrapolation).

NAVITAIRE may utilize subcontractors to perform its obligations under this Agreement provided, however, that (a) any such subcontracting to be performed on Customer's premises will be subject to Customer's prior written consent, not to be unreasonably consent withheld, (b) any such subcontracting will not relieve NAVITAIRE of any liability hereunder, and (c) any such subcontractors will be subject to a duty of confidentiality for which (i) Customer is an intended third party beneficiary, and (ii) is sufficient such that such subcontracting allows NAVITAIRE's performance hereunder to remain in compliance with applicable privacy laws.

3.2 On a rolling three (3) year basis, as measured from the time each record is created, NAVITAIRE will keep complete and accurate books, records and documents from which may be determined the basis for billing Customer and for compliance with this Agreement. Such books will be maintained in a fashion acceptable under Generally Accepted Accounting Practices. Such books, records, and accounts will be open for inspection, examination, audit and copying by the Customer or the Customer's auditors. Client and its auditors will use commercially reasonable efforts to conduct such audits in a manner that will result in a minimum of inconvenience and disruption to NAVITAIRE's business operations. Audits may be conducted only during normal business hours and no more frequently than annually unless material issues are discovered. Customer and its auditors will not be entitled to audit: (i) data or information of other customers of NAVITAIRE; (ii) any NAVITAIRE proprietary data including cost information unless such is the basis of a reimbursable or pass-through expense; or (iii) any other Confidential Information of NAVITAIRE that is not directly relevant for the purposes of the audit. Customer will provide NAVITAIRE with reasonable prior written notice of an audit. NAVITAIRE will use commercially reasonable efforts to cooperate in the audit, will make available on a timely basis the information reasonably required to conduct the audit and will assist the designated employees of customers or its auditors as reasonably necessary. Any

4

request for additional assistance will constitute a new service request. All information learned or exchanged in connection with the conduct of an audit, as well as the results of any audit, constitutes Confidential Information of Customer and NAVITAIRE and will be subject to Section 99 below. Customer will not use any competitors or NAVITAIRE to conduct such audit. Upon the request of Customer, NAVITAIRE will promptly identify any such competitors. The auditors and other representatives of Customer will execute and deliver such confidentiality and non-disclosure agreements (naming NAVITAIRE as a third party beneficiary of such confidentiality obligations) and comply with such security and confidentiality requirements as NAVITAIRE may reasonably request in connection with such audits. All audits will be conducted at Customer's expenses.

3.3 In the performance of this Agreement, NAVITAIRE will comply with statutes, regulations, ordinances, and orders of the Federal Government and other a jurisdictions applicable to NAVITAIRE as a provider of Hosted Services in respect to non-discrimination in employment and facilities including, without limitation, the provisions contained in Executive Order 11246, as amended and as it may be further amended in the future, titled "Equal Employment Opportunity" and in 41 C.F.R. §§ 60-1.4(a), 60-250.4 and 60-741.5(a) which are incorporated herein by reference. NAVITAIRE further agrees that it will complete and return such forms and respond to such inquires as the Customer may provide or ask, at Customer's expense, in connection or related to NAVITAIRE's being or use of small, HUBZone, small disadvantaged, and women-owned small businesses for the services under this Agreement and otherwise.

4 Customer Obligations

4.1 General Obligations. Customer shall comply with the obligations set forth herein including, but not limited to, those set forth in Exhibits A, B, F, G, H and J.

4.2 Access and Cooperation. Customer will provide NAVITAIRE with access to and use of its data, internal resources, and facilities, and shall otherwise cooperate with NAVITAIRE as reasonably required by NAVITAIRE, in connection with the implementation and provision of Hosted Services. NAVITAIRE will reasonably coordinate such requirements with Customer.

4.3 Notice of Increased Usage and Hosted Services Processing Capacity. NAVITAIRE'S Hosted Services capacity available to Customer is based on a calculation of three (3) times the volume of Passengers Boarded listed as Monthly Minimum Passengers Boarded Guarantees, as defined in Exhibit A, Section 8.1 that result divided by two hundred forty (240) business hours in the month (based on twenty (20) business days times twelve (12) business hours per day) to equal the number of peak hour Segment bookings per hour during a calendar month. Correspondingly, the peak hour capacity available to Customer for "Availability Requests" is three (3) times the Look to Book ratio as outlined in Exhibit A, Section 8.1. NAVITAIRE will not be obligated to fulfill service level parameters, as outlined in Exhibit A, Section 9 and Exhibit F, Section 9, when Customer's volume exceeds the peak hour capacity as defined in this paragraph, but will make commercially reasonable efforts to do so.

5

Costumer agrees to use commercially reasonably efforts to provide NAVITAIRE, on a confidential basis and according to a NAVITAIRE pre-defined process, at least thirty (30) days advance written notice of any marketing initiatives, acquisitions, alliances, schedule changes, or promotions that may materially increase Customer's usage of the Hosted Services or otherwise adversely impact the Hosted Services System performance. Examples of this are: free ticket/$0 fare promotions, new hub announcements, significant additional aircraft purchases, etc. For the purposes of this Section, increases that may adversely impact the Hosted Services are defined as increases that generate a response greater than the peak hour capacity as defined in this paragraph. NAVITAIRE will work with the Customer to attempt to reasonably provide additional capacity. If Customer requires additional capacity above three (3) times the peak hour Segment bookings per hour for bookings and/or Availability Requests, NAVITAIRE will provide a quote to Customer based on the requirements and scope desired, and the timeline on which such additional capacity can be made available to Customer.

NAVITAIRE provides Customer with completed travel historical data storage capacity equal to                                                                Three (3) months of historical PNR level booking activity detail available on-line and accessible from the Hosted System interfaces. Data storage requirements in excess of three (3) months are included as an additional service for the fees as outlined in Exhibit A Section 8.1.4.

4.4 Annual Segment Forecast Update. Customer agrees to provide NAVITAIRE each October with preliminary projected annual segment volume forecast for the following year, and will provide more accurate projections when a board-approved plan is available. NAVITAIRE will use Customer's segment forecast for business planning purposes for providing Hosted Services. It is acknowledged that such projections will not be binding on Customer and are intended for planning purposes only.

4.5 Customer Contacts. Customer initially designates the person set forth in Exhibit D, Section 2 as the Customer Account Liaison, being the primary authorized contact for account management, project funding, performance, payment, and other commercial issues with respect to the Hosted Services. Customer further initially designates the person(s) set forth in Exhibit D, Section 5 as the Customer Authorized Support Contact(s), being the authorized contact(s) to utilize the telephone support and Internet technical support system. Customer will ensure that all Customer Authorized Support Contact(s) will have received adequate training on the Hosted Services.

4.6 Omitted.

4.7 Use by Customer. Hosted Services and Confidential Information of NAVITAIRE are for the sole and exclusive use of Customer. Customer may, however, permit agents hired by Customer or Customer's subcontractors and their employees to access the Hosted Services solely for the purpose of procuring Hosted Services for and on behalf of Customer; provided that: (a) Customer will be responsible for ensuring such agents and subcontractors comply with the terms hereof, including confidentiality obligations; and (b) such agents and

6

subcontractors are not competitors of NAVITAIRE, it being acknowledged that Customer may reveal a mutually agreed redacted copy of this Agreement to such agents as reasonably required in connection with the foregoing. From time to time, at NAVITAIRE's request, Customer shall provide a list of the entities to which such access has been provided and Customer will respond to each such request within fifteen (15) days. Customer will cooperate with NAVITAIRE in investigating any alleged misuse of the Hosted Services. Customer may not transfer any Confidential Information of NAVITAIRE, in any form whatsoever without the prior written consent of NAVITAIRE, except as reasonably required to use the Hosted Service as permitted under the foregoing, provided that in no event may Confidential information be shared with direct competitors of NAVITAIRE. Any transfer of or access to the Hosted Services or Confidential Information of NAVITAIRE in violation of this Section shall constitute a material breach of this Agreement.

4.8 Training.

6.4 Fee Adjustment

6.4.1 Service Fees. During the Initial Term as stated in Section 5.1 hereof, NAVITAIRE will not increase the Service Fees for the Hosted Services functionality specified in Exhibit A, Section 6, Exhibit B, Section 7, Exhibit F, Section 7, Exhibit G, Section 7, Exhibit H, Section 7, and Exhibit J, Section 7.

6.4.2 NAVITAIRE reserves the right to offer a Major Release which may include additional significant enhancements such as APIs, code-share, and GDS Type A connectivity, at an additional charge above the fees described in Exhibits A B, F, G, H and J of this Agreement.

In the event that Customer accepts a significant enhancement which will incur additional Service Fees, such fees will be communicated to Customer in advance, in writing, and upon Customer's written acceptance, will be added to the applicable Service Fees.

6.4.3 Support Fees. The Support Fees described in Exhibits A, B, F, G, H and J shall be adjusted annually on January 1 of each year to account for inflation. During the term, if the Employment Cost Index for Professional, Specialty and Technical Occupations, as published by the United States Bureau of Labor Statistics of the Department of Labor ("ECI"), shall, commencing the first January 1 following the Effective Date, on any January 1 (the "Current Index") be higher than the ECI twelve (12) months prior thereto, (the "Base Index"), then, effective as of such then current January 1, the Support Fees then in effect shall be increased by the percentage that the Current Index increased from the Base Index. In such event, NAVITAIRE shall provide to Customer a recalculation of the affected amounts. If the Bureau of Labor Statistics ceases the publication of the ECI or substantially changes or alters the content and format of the ECI, then NAVITAIRE may substitute another comparable measure published by a mutually agreeable source. If such change is merely to redefine the base year for the ECI from one year to another year, Customer and NAVITAIRE shall continue to use the ECI but shall, if necessary, convert either the Base Index or the Current Index to the same basis as the other by multiplying such index by the appropriate conversion factor. In no event will the increase for Support Fees exceed [***] in any one year period.

6.4.4 Material Change. If there is a material change in the environment affecting the cost of operation or market price of airline reservation systems then, at the time of the seven year anniversary of the agreement, both parties agree to, in good faith, review the commercial details of this agreement for the remaining 3 year period with the objective of mutually agreeing any changes to the commercial details of this agreement for the remaining 3 year period in order to reflect such material change.

11

6.4.5 Notice. NAVITAIRE shall give Customer not less than ninety (90) days prior written notice of any changes to any Service Fees or Support Fees.

6.5 Failure to Pay. If Customer fails to pay any sum not in dispute within thirty (30) calendar days of the date due, NAVITAIRE may provide written reminder notice of such failure to Customer (this notice also constitutes the notice described in Section 5.2.1(b)). If, within ten (10) calendar days of delivery of such written notice such sum remains unpaid, NAVITAIRE may, without breach of this Agreement, discontinue performing under this Agreement until all due but unpaid payments are received.

6.6 Taxes. Customer shall pay, or if NAVITAIRE so requires reimburse NAVITAIRE for, for all taxes in connection with this Agreement including, but not limited to, sales, use, excise, value-added, goods and services, consumption, and other similar taxes or duties. Should any payment for service, product or technology provided by NAVITAIRE be subject to withholding tax by any government, Customer shall reimburse NAVITAIRE such withholding. Each Party shall provide and make available to the other Party any resale, exemption, multiple points of use certificates, treaty certification and other exemption information reasonably requested by the other Party. If Customer shall pay any tax incurred in connection with this Agreement; Customer agrees to remit to NAVITAIRE within 30 days of issue, tax documents which support the payment of such taxes.

Each party shall defend the other party from any third party claims that any product, service, information, materials or other item provided by such party under this Agreement infringes any presently existing third party patent or copyright; and indemnify such party for any damages awarded in relation to such claim; provided that, however, a party shall have no defense or indemnity obligation under this Section 8.1 to the extent any such infringement results from: (a) the use of any software provided by the party seeking indemnification in combination, operation or use with software or hardware not provided by such indemnifying party; provided that, however, such exclusion shall not apply to the use by the Customer of the Hosted Services System in connection with the hardware and software identified on the applicable Exhibit hereto; (b) the use of any Hosted Services System in a modified state which was not authorized by the indemnifying party; or (c) use of a version of the software included in the Hosted Services System without having implemented all of the updates within a reasonable period after such updates were provided by the indemnifying party and the indemnifying party was advised that such update was

15

intended to address an alleged infringement. Without limiting the foregoing indemnification obligations, if any product, service, information, material or other item of the indemnifying party is, or in the indemnifying party's opinion is likely to be held to be, an infringing material, then the indemnifying party will, at its option: (a) procure the right to continue using it; (b) replace it with a non-infringing equivalent acceptable to the other; (c) modify it to make it non-infringing in a fashion acceptable to the other; or (d) if none of the foregoing can be accomplished in a commercially reasonable manner, cease using, and require the indemnified party to cease using such item, and if such cessation renders it impractical to continue the contractual relationship contemplated hereby, either party may also terminate this Agreement. The foregoing remedies constitute the indemnified party's sole and exclusive remedies and the indemnifying party's entire liability with respect to infringement.

8.2 Except for claims covered by Section 8.1, Customer agrees to indemnify and hold NAVITAIRE harmless from third party claims arising out of Customer's use of the Hosted Services and reimburse NAVITAIRE for all expenses (including counsel fees and court costs) incurred by NAVITAIRE in connection with such claim.

The indemnifying party shall have the right, at its sole cost, expense, and liability, to appoint counsel of its choice and to litigate, defend, settle or otherwise attempt to resolve any such claim, provided that the indemnified party shall have the right to consent to any settlement, which consent will not be unreasonably withheld.

NAVITAIRE further agrees to initiate, mutually with the Customer, project-scope-analysis and project-planning communication to establish the final schedule for Implementation Services.

• Airport facility use agreements.

• Credit card settlement and authorization agreements.

• Extract. An extract process will retrieve all reservations that have a flight record with an open future travel date. Only complete, or valid, reservations will be extracted from the previous reservation system data file.

• Conversion. After a 'block' of reservation data is extracted, the corresponding output file will be transferred to the new environment. A data validations routine will perform audits of the data quality.

• Import. Upon completion of the first extract file of clean data, an import routine will transfer the clean data to the New Skies compliant databases in segmented extracts. While the first is transferring, a concurrent process will commence on the second extract, transfer and import to expedite data transfer.

8.6 Payment of Implementation Fees. Immediately upon signing this Agreement, all Implementation Fees are due and payable. The Implementation Fee due on signing is USD [***]. Any remaining balances of all Implementation Fees are due and payable on the earlier of: (a) the day the first production reservation is made using the Hosted Reservation Services; or (b) the Target Date as detailed in Exhibit A, Section 3.9.1 provided, however, that NAVITAIRE does not request a delay as described in this Exhibit A, Sections 8.7.2 and 8.7.4.

8.7 Fee Commencement after Implementation. The following four (4) scenarios will determine the commencement schedule for the monthly recurring Service Fees as outlined in Section 8.1 of this Exhibit and the due date for the remaining balances of the implementation fees:

8.7.1 Implementation by Target Date. Upon availability of the Hosted Reservation Services for use by Customer, effective on the Target Date as detailed in Exhibit A, Section 3.9.1, all remaining implementation fees are due and applicable monthly recurring Service Fees will commence. These fees will commence regardless of actual use of Hosted Reservation Services or subsequent delay by Customer.

8.7.2 Requested Delay by NAVITAIRE. In the event that NAVITAIRE requests a delay in order to complete remaining Implementation Services, the remaining implementation fees will be due and applicable monthly recurring Service Fees will commence only on the commencement of Customer's use of the Hosted Services. NAVITAIRE will provide written notice of the new planned Target Date and outline remaining Implementation Services.

58

8.7.3 Requested Delay by Customer. In the event the Customer requests a delay in the completion of Implementation Services past the Target Date, remaining implementation fees are due and any monthly recurring Service Fees will remain effective for the duration of the customer-initiated delay. If such requested delay results in rescheduling portions or all of the remaining Implementation Services to the next available timeframe as evaluated by NAVITAIRE, no Service Fees will be in effect for the duration delay due solely to NAVITAIRE'S resource availability.

NAVITAIRE reserves the right to apply additional implementation fees as are necessary and mutually agreed on when rescheduling the Implementation Services due to Customer request. All fees as described in the Agreement and Exhibit A, Section 8.2 are to be applied based on the scheduled Target Date.

8.7.4 Mutual Agreement for Delay. In the event that both NAVITAIRE and the Customer agree to delay in order to complete the required Implementation Services, the remaining implementation fees will be due and the applicable monthly recurring Service Fees will commence on the newly agreed Target Date for the Implementation Services.

59

9 Service Levels and Service Level Targets

9.1 Service Level Scope. The Service Levels contained in this Section represent the target service performance for the provision of the Hosted Reservation Services. Metrics, measurement, and reporting will create performance assessment measures that apply to operations services in the following three service categories:

• System availability targets.

• Metrics, measurement, and reporting.

• Remedies and corrective action.

9.2 Service Level Targets

9.2.1 System Availability. NAVITAIRE will seek to provide Customer with an overall Minimum System Availability Target of ninety-nine point eight percent (99.8%) of all Reporting Period Minutes for the applicable Reporting Period. Interrupted Service Minutes will be measured and used to determine the percentage of monthly Hosted Services System availability,

(a) Interrupted Service will be defined as a complete system availability outage, including:

• NAVITAIRE controlled primary circuit network line being down and will be considered a 100% outage for the purposes of calculating any applicable service credit.

• NAVITAIRE controlled server or router being down and will be considered a 100% outage for the purposes of calculating any applicable service credit.

• System Error which causes the system to be completely unavailable and will be considered a 100% outage for the purposes of calculating any applicable service credit.

• Also included for the purposes of calculating the Service Credits will be the following partial outages (Service Credits not to exceed 100%) that are due to NAVITAIRE'S sole cause and under NAVITAIRE'S sole control.

a) the inability of booking a reservation at the Customer call center which will be considered a twenty percent (20%) outage for the purposes of calculating any applicable service credit.

b) the ability of checking in passengers at a single airport at the same time which will be considered a ten percent (10%) outage for the purposes of calculating any applicable service credit.

60

c) the ability of checking in passengers at all airports at the same time which will be considered a forty percent (40%) outage for the purposes of calculating any applicable service credit.

d) the inability of booking a reservation on the Customers booking web site which will be considered a seventy five percent (75%) outage for the purposes of calculating any applicable service credit.

(b) Network Responsibilities. The diagram below shows those hardware components, network components (excluding the internet), and the software that resides on those components that are owned from a service level perspective by NAVITAIRE and those items that are owned by the Customer. Items that are contained within the dotted-line (in the upper left corner) are the responsibility of Customer. During the event of an Interrupted Service, NAVITAIRE is responsible for errors that occur involving the hardware components, network components, and the software that reside outside of the dotted-line area.

(c) Planned Downtime. NAVITAIRE acknowledges that the system will be operated, maintained, and upgraded in such a fashion as to minimize the incidents in which the system will be unavailable. It is the expectation that under normal conditions that this Planned Downtime will be less that 60 minutes per week, NAVITAIRE will make reasonable efforts to perform such activities during Customer off-peak hours. In doing so, it is acknowledged that, for temporary periods coordinated with Customer so as to ensure that they occur when Customer's required capacity is expected to be below that

61

which will be available, NAVITAIRE will be permitted to reduce the available capacity of the system. NAVITAIRE will coordinate with Customer to determine the best time for Customer for when the system can be unavailable. It is however, acknowledged and understood that in the event that NAVITAIRE reasonably determines that a critical System Change is required, NAVITAIRE can inform Customer of any required Planned Downtime. NAVITAIRE acknowledges that a precondition to any such activities will be a recovery plan to immediately restore the services to full operations.

9.2.2 Incident Problem Request (IPR) Service Response. NAVITAIRE will commit ton the Emergency response targets below for each IPR logged System Error.

	Emergency IPR Response
Customer Communication	Emergency
Acknowledgement and Initial Response	15 minutes
Update	Every 30 minutes

9.2.3 In the event that the overall achieved Minimum System Availability Target in any Reporting Period falls below ninety-nine point nine (99.9%), It is agreed that the parties will engage in an Executive Review Meeting for which a senior officer of NAVITAIRE as well those with knowledge of the cause for such failure will meet at the offices of Customer with the relevant personnel from Customer and will present NAVITAIRE's plan that it will implement to seek to ensure that a Minimum System Availability Target of ninety-nine point nine (99.9%) will be achieved in future Reporting Periods.

9.3 System Errors and Emergencies

9.3.1 System Error Reporting. Customer may report an identified Hosted Reservation Services System Error at no additional cost using the Remedy IPR schema. A System Error is defined in Section 9.4.4 of this Exhibit A.

9.3.2 System Error Classification. When Customer reports an IPR for a System Error, it will be assigned a priority based on the severity of the issue. These priorities will be assigned using the following table:

Impact Analysis	Business Functionality
	No loss of business function	Partial loss of business function. Work-around exists	Partial loss of business function. No work-around exists.	Complete loss of business function. Work-around exists.	Complete loss of business function. No work-around exists.
Immediate Impact is significant. Affects many and/or critical users.	NA	Emergency	Emergency	Emergency	Emergency
Immediate impact is moderate. Affects few and/or non-critical users.	Low	Medium	High	High	Emergency
Immediate impact is marginal, Affects few or no users.	Low	Medium	High	Medium	High

62

An example of an "Emergency" System Error might include:

• Hosted Reservation Services are totally unavailable due to a NAVITAIRE controlled communication line.

An example of a "High" System Error might include:

• Cannot change any airline schedules through Schedule Manager.

• Cannot load new fares through Fares Manager.

• Unable to generate confirmation itineraries for Internet customers.

• Settlement files are delayed by one day in being sent to the settlement bank.

An example of a "Medium" System Error might include:

• Slow system response for specific tasks.

9.3.3 Emergency Response Procedure. In the event of a Customer Emergency, the NAVITAIRE Support Centre may be contacted for assistance, according to the procedures outlined in Section 5.4 of this Exhibit.

9.3.4 NAVITAIRE Support Communication Targets. For High, Medium, and Low IPRs, NAVITAIRE will set the response times as response target times, and these will be measured during the initial months of the Hosted Reservation Services. NAVITAIRE's resolution targets are provided in the Support User Guide, available on NAVITAIRE's Customer Care web site.

	IPR Severity Classification and Response Targets
Customer Communication	High	Medium	Low
Acknowledgement and Initial Routing	4 hours	24 hours	48 hours
Updates	Customer will receive electronic notification whenever data is needed or incident is resolved, status changed, or notes updated.

9.4 System Changes

9.4.1 Change Control. All events that impact application software, custom software, systems software, or hardware could be covered by Change Control. The Change Control process effectively plans and facilitates changes to the Hosted Services System, including ownership for mitigating problems that may occur with a change to minimize any

63

associated downtime. This function is responsible for coordinating and controlling all change administration activities (i.e., document, impact, authorize, schedule, implementation control), and determining if and when a change will be implemented in the enterprise environment.

9.4.2 Enhancements. An "Enhancement" is a request for a new report or application or an improvement to an existing application related to usability, performance, additional functionality, or flexibility, Enhancements will be logged in the Software Change Request (SCR) schema in Remedy. Such requests can be in response to:

Mandates controlled by external third parties including governments, governing industry bodies such as International Air Transport Association [IATA], Société Internationale de Télécommunications Aéronautiques [SITA], or airport authorities. Examples include:

• Taxes, fees, security issues, immigration.

• Airport technology issues that impact airlines such as bag tag, Common Use Terminal Emulator (CUTE), or CUBE.

Customer requests that are initiated through a direct request, user conference, or through Customer's NAVITAIRE Account Manager. Examples include:

• Competitive advantage.

• improved passenger services.

• Specific client requirements.

• Improved business management.

Internal requests that are initiated through the sales cycle, Technology, Development, or NAVITAIRE line of business. Examples include:

• Cost reduction initiatives.

• Product obsolescence.

• Corporate business plan objective.

9.4.3 Urgency Classifications for Enhancements. Enhancements will be assigned a priority according to the criteria in the table below. If there is a disagreement as to the priority of the requested Enhancements, these will be decided between NAVITAIRE Account Manager and Customer Account Liaison. If this cannot be resolved at this level, it will be escalated to the respective Executive Sponsors for determination

64

Customer Urgency		Description
Very High (Emergency)	A requirement from a business critical third party or other outside influence such as an airline buyout, purchase of another airline, a new government regulation, or a requirement that cannot be completed in a manual nature without severe negative impact. Such requests are Urgent only if a third party controls the requirement, it is non-discretionary to the customer, and the third party places an immediate time constraint on the customer. Note: Documentation from the governing entity, which clearly states the nature of the requirement, the time frame allowed for implementation, and the penalties for noncompliance may be required. Due to the nature of an Emergency request, we expect to receive no more than 2-3 such requests per month. Every attempt will be made to meet the established regulatory deadline communicated in these instances; however should the deadline be compromised NAVITAIRE will communicate specific issues that may make this deadline unattainable with an estimate of when it can be completed. Examples: Adding Security Watch - a government or industry requirement that would inflict severe financial penalties if not met and demanded a quick implementation. Adding the EURO as a form of currency - a specific governmental requirement that was dictated to the customers and demanded a quick implementation.
High	A requirement from a business critical third party or outside influence such as an airline buyout, purchase of another airline, a new government regulation, or a requirement that cannot be completed in a manual nature without severe negative impact, but DOES NOT have an immediate time constraint placed on the customer by the third party.
	Note:	Such requests are classified as High to prevent them from becoming Very High/Emergencies. A new business requirement that cannot be completed in a manual nature without severe negative impact. Such requests are not Emergencies because the request is discretionary to the customer.
	Examples:	Printing French Itineraries for domestic French flights - a governmental requirement that provided sufficient time to respond to the need. Changing to a new bank - a customer-driven requirement that is critical to customer daily operations.
Medium	Supports all required Hosted Services System operations; the request is required eventually but could wait until a later release if necessary. Would enhance the product, but the product is not unacceptable if absent. More of a want than a need, but would provide benefit to the customer.
	Examples:	Adding support for additional auxiliary services, such as car-hire or insurance. Adding support of seat assignment capability for Computerized Reservation System (CRS) bookings. Adding new check-in commands or short-cuts that would save time and effort for the agents. Adding new features or functions in the Irregular Operations (IROP) program to increase efficiency of passenger handling.
Low	A functional or quality enhancement that corrects an aesthetic problem or improves usability from the customer's perspective. It does not greatly affect or alter core functionality.
	Examples:	Enabling a pop-up message of "Are you sure" for bags weighing > 100Kg. Adding the ability to alter the 'flow' of the SkySpeed booking process as a user configurable option. Adding support for additional languages for SkySpeed (localization). Adding more feeds (imports or exports) to third party packages for data sharing. Making minor adjustments to screen layouts or design to increase readability. Adjusting reports to increase readability and decrease questions to support.

65

9.4.4 System Errors. A System Error occurs when functionality that is included in the NAVITAIRE product user documentation is currently not working on Customer's site in the manner that it is described in the documentation that shall be reasonably up to date.

Note: The Customer must refer to the documentation that matches the version of software they are running. If Customer wants a feature that is not currently included in their software version, but the feature is included in a

later software version, Customer must upgrade their software to that version to be able to take advantage of the new features and functionality.

System Errors detected during testing in the Customer's test environment should also be logged through Remedy with a reference to the test database code. NAVITAIRE will respond to all Emergency IPRs for the test environment within five (5) business days.

No failure of any reconfiguration by Customer of a Configurable Template shall be deemed to be or can create a System Error.

9.4.5 Releases. NAVITAIRE software changes are bundled into work units called releases. The type and content of each release will vary according to criteria listed in the chart below.

Criteria	Releases
	Major	Minor	Emergency
Driven by	Strategy and product direction	Bug fixes to previous releases of software	Severity 1 bug fixes or emergency enhancements
Target content	Enhancement - 60% Bug Fix - 25% Emergency - 15%	Enhancement - 25% Bug Fix - 60% Emergency - 15%	Enhancement - 0% Bug Fix - 0% Emergency - 100%
Description	Changes in the architecture, to the database, or that affect many different products in the NAVITAIRE product suite	Bug fixes, new reports, new stand-alone programs or features. Data structure changes that do not impact, the database or architecture	Critical changes to the software stemming from Severity 1 bug fixes or emergency enhancements
Approximate schedule	Annual	Quarterly to monthly	As needed or in the next available release
Implementation requirement	Downtime as required.	Downtime as required.	Downtime as required.

66

9.4.6 Release Stabilization Period. Following a Major Release as defined in Section 9.4.5 of this Exhibit, Hosted Services System performance for all or some of the Minimum System Availability Targets are subject to a reduction to ninety five percent (95%) during periods of time identified as Stabilization Periods. A Stabilization Period is defined as follows:

• As used herein, the term "Stabilization Period" means the first thirty (30) days following a Major Release. During the Stabilization Period incidents related to the functionality added for a particular third party service in the release that are directly related to that third party service are exempted from the Service Levels performance target. The Stabilization Period will not apply to Major Release 'sub-releases' or fixes.

During this time NAVITAIRE will work with Customer to periodically evaluate and refine the service level measures applicable to such third party service offerings,

9.5 Notification of Increased Usage. As previously stated in Section 4.3 of this Agreement, Customer agrees to use commercially reasonable efforts to provide NAVITAIRE with the designated advance notice of significant volume increases, according to a NAVITAIRE defined process.

9.6 Service Levels Reporting

9.6.1 General. Regular, standardized Service Levels reporting provides a common denominator, which measures and evaluates service performance. This provides a basis on which conclusions can more easily be drawn as to the actual Service Levels achieved. NAVITAIRE will monitor and measure performance of specified Service Levels items and send a Monthly Performance Report to Customer for review and approval. The report will be structured for Customer's internal use and metrics will be generated and distributed on a monthly basis.

9.6.2 Report Information

• Monthly Performance Report. The NAVITAIRE Account Manager will submit a Monthly Performance Report by the sixth business day of the subsequent month following the Reporting Period to the Customer Account Liaison. The report will contain the monthly indicator of Service Levels statistics and will be transmitted via email unless otherwise requested by the Customer. The report will also summarize all Interrupted Service Reports for the Reporting Period.

• Interrupted Service Report. The NAVITAIRE Account Manager will provide an Interrupted Service Report, created by the Global Support Centre, following an outage or Interrupted Service. This report will summarize circumstances, identified cause (if known)

67

and will outline any identified corrective action. Each Interrupted Service Report will be given a tracking number for reference on the Monthly Performance Report.

9.6.3 Report Follow Up. If Customer has any questions or objections to the report, they will notify their NAVITAIRE Account Manager within ten (10) business days of receiving the report and NAVITAIRE shall respond within ten (10) business days of notification. If the parties cannot agree on the measurements reported, the matter will be escalated to the respective Executive Sponsors, and, if still unresolved, will be escalated as outlined in Section 19.5 of this Agreement (dispute resolution procedures).

9.7 Review and Correction

9.7.1 NAVITAIRE Account Manager Review. In addition to Support Centre Support and Emergency services, the NAVITAIRE Account Manager will coordinate a teleconference with the Customer Account Liaison within twenty-four (24) hours of the Interrupted Service to discuss the details outlined in the Interrupted Service Report and to update the Customer on any identified cause or status. The NAVITAIRE Account Manager will close the Interrupted Service Report with the Customer Account Liaison upon final report of identified cause and any outline of corrective action.

9.7.2 Executive Review. Upon the request of the NAVITAIRE or Customer Account Liaison, an Executive Sponsor teleconference and a further escalation to the CEO or President level of each company may be made depending on the severity of the Interrupted Service.

9.8 Remedies and Corrective Action. The remedies and corrective action described below will be applied with respect to each Reporting Period, which commences sixty (60) days following completion of Implementation Services. Conflict and Exhaustion of Provisions as stated at the beginning of this Exhibit will apply to this Section,

9.8.1 Corrective Action. The NAVITAIRE Account Manager shall monitor corrective action and report to the Executive Sponsors. In the event that Minimum System Availability Targets are not met during the Reporting Period, the NAVITAIRE Account Manager shall initiate corrective action during the subsequent Reporting Period. NAVITAIRE shall, at its own expense, use commercially reasonable efforts to correct the deficiency in order to meet future Minimum System Availability Targets.

9.8.2 Failure Notification. Upon a second failure of NAVITAIRE to meet Minimum System Availability Targets, the issue shall be escalated to the CEO or President level of each company. Customer may notify NAVITAIRE, in writing, of the failure to meet Minimum System Availability Targets. Upon receipt of such notice, NAVITAIRE will begin reporting System Availability in weekly Reporting Periods and

68

will communicate to Customer within five (5) business days and in writing the status of improvement in performance. Subject to the remaining terms hereof, if NAVITAIRE fails to meet the Minimum System Availability Target for the Hosted Reservations Services in any given calendar month (Reporting Period) in any consecutive twelve (12) month period, NAVITAIRE will provide Customer a credit of the Monthly Recurring Service Fees for such month according to the following schedule:

(i) First Month Service Level is missed - [***] of the Monthly Recurring Service Fees for the Hosted Reservations Services as multiplied by the applicable percentage of outage as detailed in Section 9.2.1 of this Exhibit A.

(ii) Second Month Service Level is missed - [***] of the Monthly Recurring Service Fees for the Hosted Reservations Services as multiplied by the applicable percentage of outage as detailed in Section 9.2.1 of this Exhibit A.

(iii) Third Month Service Level is missed - [***] of the Monthly Recurring Service Fees for the Hosted Reservations Services as multiplied by the applicable percentage of outage as detailed in Section 9.2.1 of this Exhibit A.

(iv) Fourth Month Service Level is missed - [***] of the Monthly Recurring Service Fees for the Hosted Reservations Services as multiplied by the applicable percentage of outage as detailed in Section 9.2.1 of this Exhibit A.

Additionally, in the event that the NAVITAIRE fails to meets a 2ndtier of the Minimum System Availability Target, which is ninety nine point five (99.5%), an additional [***] of the Monthly Recurring Service Fees for the Hosted Reservations Services will be added to the applicable credit due Customer as defined above.

Additionally, in the event that the NAVITAIRE fails to meets a 3rd tier of the Minimum System Availability Target, which is ninety eight percent (98%), an additional [***] of the Monthly Recurring Service Fees for the Hosted Reservations Services will be added to the applicable credit due Customer as defined above.

User Interface
SkyLedger provides a user interface for: a) viewing and managing accounts, b) viewing journals and account mappings to allow customization accounts, and c) viewing journal entries to track how transactions are applied to those specific accounts. The following six user interfaces will be included in SkyLedger:
•	Accounts. The accounts user interface will be used to insert, update, and delete entries from the SkyLedger account table, center table, and company account center table. These tables in turn are used to validate entries to the SkyLedger account mapping table.
•	Journal Maintenance. The journal maintenance user interface will be used to insert, update, and delete entries on the SkyLedger journal entry table. This table in turn will be used to validate entries to the SkyLedger account mapping table.
•	Journal Approval. The journal approval user interface will be used to approve the debit/credit balance for each journal entry. Please note that this interface is intended to be used in conjunction with the SkyLedger journal entry detail report. Quality Assurance and management approval of a journal entry is required before data related to this journal entry may be bridged to the user via the automated monthly G/L feed (where the carrier has requested user-approval of the journal entry balance).
•	Mappings. The mappings user interface will be used to insert, update, and delete entries from the SkyLedger account mapping table. This table in turn will be used to assign a debit account/center and credit account/center to accounting transactions based upon the type of accounting event (account event/account code) and the specific characteristics of the transaction (mapping fields). The account mapping table also enables individual accounting transactions to be classified under the proper company code and journal entry.
•	Currency Maintenance. This user interface will allow the user to enter the exchange rate from each currency to the host currency at the company level with an effective date for each exchange rate.

93

•	Service Types. This user interface will allow the carrier to identify each service type and specify whether or not the revenue related to that service will be earned at the time of booking or the time of flight.
Revenue Accounting System Data Storage and Access
General Features
•	Online access for historical revenue accounting system data up to 12 months from current date.
•	Access to historical revenue accounting system data more than 12 months prior is available via archive database application or standard media (e.g. tape) stored offsite. Access to data more than 12 months prior is provided upon request through Internet based customer support facility at a price to be quoted upon receipt of such request.

10 System Errors and System Changes

10.1 System Errors

10.1.1 System Error Definition. A System Error occurs when functionality that is included in the NAVITAIRE product user documentation is currently not working on Customer's site in the manner that it is described in the documentation.

Note: Customer must refer to the documentation that matches the version of software they are running. If Customer wants a feature that is not currently included in their software version, but the feature is included in a later software version, Customer must upgrade their software to that version to be able to take advantage of the new features and functionality.

System Errors detected during testing in the Customer's test environment should also be logged through the NAVITAIRE internet support tool with a reference to the test database code. NAVITAIRE will respond to all Emergency IPRs for the test environment within five (5) business days.

10.1.2 System Error Reporting. Customer may report an identified Hosted Revenue Accounting Services System Error at no additional cost using the Remedy IPR schema. A System Error is defined in Section 10.1.1 above.

99

10.1.3 System Error Classification. When Customer reports an IPR for a System Error, it will be assigned a priority based on the severity of the issue. These priorities will be assigned using the following table:

Impact Analysis	Business Functionality
	No loss of business function	Partial loss of business function. Work- around exists	Partial loss of business function. No work- around exists.	Complete loss of business function. Work- around exists.	Complete loss of business function. No work- around exists.
Immediate impact is significant. Affects many and/or critical users.	NA	Emergency	Emergency	Emergency	Emergency
Immediate impact is moderate. Affects few and/or non-critical users.	Low	Medium	High	High	Emergency
Immediate impact is marginal. Affects few or no users	Low	Medium	High	Medium	High

Examples of an "Emergency" System Error might include:

• Hosted Revenue Accounting Services are totally unavailable due to NAVITAIRE controlled communication line.

• Customer did not receive the daily Postings Report.

An example of a "High" System Error might include:

• Reporting Services is not displaying data accurately.

An example of a "Medium" System Error might include:

• Slow system response for specific tasks.

100

10.1.4 Emergency Response Procedure. In the event of a Customer Emergency, the NAVITAIRE Support Centre may be contacted for assistance, according to the procedures outlined in Section 5.4 of this Exhibit.

10.2 System Changes

10.2.1 Change Control. All events that impact application software, custom software, systems software, or hardware could be covered by Change Control. The Change Control process effectively plans and facilitates changes to the Hosted Revenue Accounting Services system, including ownership for mitigating problems that may occur with a change to minimize any associated downtime. This function is responsible for coordinating and controlling all change administration activities (i.e., document, impact, authorize, schedule, implementation control), and determining if and when a change will be implemented in the enterprise environment.

10.2.2 Enhancements. An "Enhancement" is a request for a new report or application or an improvement to an existing application related to usability, performance, additional functionality, or flexibility. Enhancements will be logged in the Support Centre Support tool. Such requests can be in response to:

(a) Mandates controlled by external third parties including governments, governing industry bodies such as International Air Transport Association [IATA], Société Internationale de Télécommunications Aéronautiques [SITA], or airport authorities.

(b) Customer requests that are initiated through a direct request, user conference, or through Customer's NAVITAIRE Account Manager. Examples include:

• Competitive advantage

• Improved passenger services

• Specific client requirements

• Improved business management

(c) Internal requests that are initiated through the sales cycle, Technology, Development, or NAVITAIRE line of business. Examples include:

• Cost reduction initiatives

• Product obsolescence

• Corporate business plan objective

10.2.3 Urgency Classifications for Enhancements. Enhancements will be assigned a priority according to the criteria in the table below. If there is a disagreement as to the priority of the requested Enhancements, these will be decided between NAVITAIRE Account Manager and

101

Customer Account Liaison. If this cannot be resolved at this level, it will be escalated to the respective Executive Sponsors for determination.

Customer Urgency		Description
Very High (Emergency)	A requirement from a business critical third party or other outside influence such as an airline buyout, purchase of another airline, a new government regulation, or a requirement that cannot be completed in a manual nature without severe negative impact. Such requests are Urgent only if a third party controls the requirement, it is non-discretionary to the customer, and the third party places an immediate time constraint on the customer.
	Note:	Documentation from the governing entity, which clearly states the nature of the requirement, the time frame allowed for implementation, and the penalties for non-compliance may be required. Due to the nature of an Emergency request, we expect to receive no more than 2-3 such requests per year. Every attempt will be made to meet the established regulatory deadline communicated in these instances; however should the deadline be compromised NAVITAIRE will communicate specific issues that may make this deadline unattainable with an estimate of when it can be completed.
High	A requirement from a business critical third party or outside Influence such as an airline buyout, purchase of another airline, a new government regulation, or a requirement that cannot be completed in a manual nature without severe negative impact, but DOES NOT have an immediate time constraint placed on the customer by the 3rd party.
	Note:	Such requests are classified as High to prevent them from becoming Very High/Emergencies. A new business requirement that cannot be completed in a manual nature without severe negative impact. Such requests are not Emergencies because the request is discretionary to the customer.
Medium	Supports all required Hosted Services System operations; the request is required eventually but could wait until a later release if necessary. Would enhance the product, but the product is not unacceptable if absent. More of a want than a need, but would provide benefit to the customer.

102

Low A functional or quality enhancement that corrects an aesthetic problem or improves usability from the customer's perspective. It does not greatly affect or alter core functionality. Examples: Adding more feeds (imports or exports) to 3rd party packages for data sharing. Making minor adjustments to screen layouts or design to increase readability. Adjusting reports to increase readability and decrease questions to support.

10.2.4 Releases. NAVITAIRE software changes are bundled into work units called releases. The type and content of each release will vary.

10.2.5 Month End Closure. SkyLedger operates with two (2) accounting periods open at all times. Prior to closing the accounting month end, Customers must ensure that following are managed:

• All flights for that month have been set to "Close" within the NAVITAIRE Reservation system.

• All no-show passengers on all flights for the month have been set to "No-Show".

• Balance in the SkyLedger Suspense account has been cleared to "Nil" balance or to a reasonable level.

Customers are required to close the accounting period within the first five (5) working days of the next month (e.g. July 2007 accounting month would be set to close by August 7th, 2007). Customers are requested to log an IPR to request NAVITAIRE Operations to close the accounting month. For example:

• July and August 2007 accounting periods are open

• July accounting period is closed no later than Monday, August 7th, 2007

• As soon as July 2007 is closed September 2007 accounting period will be open

In the event Customer has not requested the earliest accounting to be closed prior to the start of the third month (in the example above this is September 2007) the NAVITAIRE Operations will close the accounting period (July in the above example). The Customer will be provided 24 hours notice that the accounting period will be scheduled for closure. This is to ensure that September booking data can be loaded and accounting is generated without any delays.

If NAVITAIRE Operations confirms the accounting close is to be scheduled and the Customer does not accept this, the Customer will be responsible for any incurred costs associated with holding back and the loading of data for subsequent months. Effort is chargeable based on time and materials at the rates listed in Section 9.3 of this Exhibit.

The Data Store Workbench (DSW) offers customers read only access to the Historical Operational Data Store (HODS) and Data Warehouse (DW) data, as well as read/write access to the Data Store Workbench (DSW) database, for custom reporting, extraction, transformation, and loading.

Customers can create and store custom objects in the DSW database, located on the same physical server as the HODS and DW, but cannot create custom objects in or modify the HODS or DW data.

The DSW database size is capped at 50GB.

Database user privileges are limited to DDL_ADMIN.

NAVITAIRE IT staff provides basic database administration services for the DSW Database which include standard data backup and recovery support.

Job scheduling is not permitted on the DSW database server. If implemented, customers will host scheduling services on their servers at their location (e.g., SQL Server Integration Services packages).

Standard New Skies reports continue to run against the HODS.

NAVITAIRE provides the following services for the Data Store Workbench:

Delivery of data committed to the New Skies database via replication articles, typically within thirty (30) minutes

Transactional Data Integrity where the data committed to the New Skies database are replicated to the DS.

Documentation includes the data model, training curriculum, and explanations of the data store architecture, replication, and support processes.

Note: This product is designed for light custom reporting and moving reservations data to another database, data warehouse, or other system outside of the New Skies environment for processing.

[6.2.36] [U.S. Bank - Signatory Agreement.pdf]

3.1 [***] If Carrier chooses to accept only one of the categories of products but later submits a Transaction outside of the selected category, Servicer and Member are not required to reject the Transaction and Carrier will be charged standard fees and expenses for that category of products. Further, if Carrier chooses a limited acceptance option, it must still honor all international cards presented for payment. If Carrier decides to implement a limited acceptance policy, it shall display appropriate signage to communicate that policy to Cardholders. Except as may be permitted by applicable local law and Operating Regulations, Carrier will not impose a surcharge for purchases made with the Card nor shall Carrier establish minimum or maximum transaction amounts as a condition for honoring Cards.

3.2 Carrier shall use reasonable efforts to cause all Agents to permit Cardholders to charge Travel Costs only in accordance with the terms and conditions of the Agreement and in compliance with applicable Operating Regulations. Carrier shall use reasonable efforts to cause compliance by Agents with all of the terms and conditions of the Agreement to be performed by Carrier or Agents. Notwithstanding any such reasonable efforts by Carrier, Carrier shall be responsible for: (i) any failure by any Agent in performing the applicable provisions of the Agreement; and (ii) the settlement of Sales Records and Credit Records completed by Agents.

3.3 Before honoring a Card, Carrier shall do the following to determine whether the Card is valid: (a) where possible, examine the format of each Card presented in connection with a purchase for authenticity and confirm, by checking the effective date and the expiration date as stated on the face of the Card, that the Card has become effective and has not expired; and (b) obtain Authorization. Neither Carrier nor any Agent shall impose a requirement on Cardholders to provide any personal information such as a home or business telephone number, home or business address, driver's license number, or a photocopy of a driver's license as a condition for honoring Cards unless such information is required or permitted under specific circumstances cited in the Agreement.

Notwithstanding the foregoing, with respect to Transactions that are not conducted face-to-face, Carrier may request from a Cardholder the information necessary to complete an address verification service request. Neither Carrier nor any Agent shall make a photocopy of a Card under any circumstances, nor shall a Cardholder be required to provide a photocopy of the Card as a condition for honoring the Card. Neither Carrier nor any Agent shall require a Cardholder, as

7

[6.2.36] [U.S. Bank - Signatory Agreement.pdf]

a condition for honoring the Card, to sign a statement that in any way waives the Cardholder's rights to dispute the Transaction. Carrier may require passengers to present personal information, including a driver's license, passport, or other picture identification, for purposes of complying with Carrier's policy or applicable law.

3.4 (a) Carrier or Agent shall obtain Authorization for the total amount of the Travel Costs before completing any Card sales Transaction (which in the case of Transactions involving paper submissions pursuant to Section 6.2(d) may require telephone Authorization). Such Authorization may be provided by any third party provider acceptable to Servicer. Authorization verifies that the Card number is valid, the Card has not been reported lost or stolen at the time of the Card sales Transaction, and confirms that the amount of credit or funds requested for the Card sales Transaction is available. Carrier or Agent will follow any instructions received during Authorization. Upon receipt of Authorization, Carrier or Agent may consummate only the Card sales Transaction authorized and must note the Authorization code on the Sales Record. For all ticket by mail, telephone or internet Card sales, Carrier must obtain the Card expiration date and forward that date as part of the Authorization.

(b) Authorization does not: (i) guarantee Carrier final payment for a Card sales Transaction; (ii) guarantee that the Card sales Transaction will not be disputed later by the Cardholder as any Card sales Transaction is subject to Chargeback; or (iii) protect Carrier in the event of a Chargeback regarding unauthorized Card sales Transactions or disputes involving the quality of goods or services. Authorization will not waive any provision of the Agreement or otherwise validate a fraudulent sales Transaction or a sales Transaction involving the use of an expired Card.

(c) In a Card sales Transaction in which a Card is presented electronically, if Carrier's Terminal is unable to read the magnetic stripe on the Card, Carrier must key-enter the Transaction into the POS Device for processing and obtain: (i) a physical imprint of the Card using a manual imprinter; and (ii) the Cardholder's signature on the imprinted Sales Record.

3.5 Neither Carrier nor any Agent shall make any Card sale to any customer in any of the following circumstances (with the exception of ticket by mail, internet or telephone pursuant to Section 3.8 permitted by the Agreement and ticket by automated machine pursuant to Section 3.9 or purchased through other CNP Transactions): (a) a Card is not presented at the time of sale; (b) the signature on the Sales Record does not appear to correspond to the signature appearing in the signature panel on the reverse side of the Card, or the Cardholder does not resemble the person depicted in any picture which appears on the Card; (c) the signature panel on the Card is blank and is not signed in accordance with the procedures specified in Section 3.6; and (d) no Authorization is received. Any Carrier or Agent completing a Transaction under the conditions in this Section 3.5 shall be responsible for such Sales Record or Credit Record regardless of any Authorization.

3.6 If the signature panel of the Card is blank, in addition to requesting Authorization, Carrier or Agent must: (a) review positive identification to determine that the user is the Cardholder; (b) indicate such positive identification (including any serial number and expiration date) on the Sales Record; and (c) require that the Cardholder sign the signature panel of the Card prior to completing the Transaction. If a Cardholder presents a Card that bears an embossed "valid from" date and the Transaction Date is prior to the "valid from" date, Carrier or Agent shall not complete the Transaction. A card embossed with a

8

[6.2.36] [U.S. Bank - Signatory Agreement.pdf]

"valid from" date in month/year format shall be considered valid on the first day of the embossed month and year. A card embossed with a "valid from" date in month/day/year format is considered valid on the embossed date

Each Sales Record shall be imprinted with the Card unless: (i) the Sales Record results from a Transaction involving Terminals which produce electronic Transaction records; (ii) the Card Transaction is a CNP Transaction; (iii) an imprinter is not available; or (iv) if for any other reason the Sales Record cannot be imprinted with a Card (if Authorization is obtained), including Card Transactions by mail, telephone or automated machine. If an imprinter is not available, the information on the Card

(c) Each Sales Record shall include on its face the items needed to complete the Settlement File required by the Servicer. Each Sales Record shall be signed by the Cardholder (except where the sale is made pursuant to CNP Transaction or automated machine transaction), which signature shall appear to be the same as the signature on the Card presented, as determined by Carrier or Agent. The Cardholder shall not be required to sign a Sales Record until the final Transaction amount is known and indicated in the "Total" column.

(d) Carrier shall not effect a Transaction for only part of the amount due on a single Sales Record except when the balance of the amount due is paid by the Cardholder at the time of sale in cash, by check, with another card or Card, or any combination thereof.

(e) If Carrier or Agent honors the Card, Carrier or Agent honoring the Card will deliver to the customer a true and completed copy of the Sales Record. The Card account number must be truncated on all Cardholder-activated copies of Sales Records. Truncated digits should be replaced with a fill character such as "x," "*," or "#," and not with blank spaces or numeric characters. All POS Devices must suppress all but the last four digits of the Card account number and the entire expiration date on the Cardholder's copy of the Electronic Sales Records generated from POS Devices (including Cardholder activated).

3.8 Carrier or Agent may enter into Card Transactions in accordance with Carrier's or such Agent's ticket by CNP Transaction program. In each such case, Carrier or Agent will complete the Sales Record (in accordance with Section 3.7) and include on the Sales Record the effective date and expiration date of the Card as obtained from the Cardholder together with words to reflect "mail order" or the letters "MO" or "telephone order" or the letters "TO," or "internet order" or the letters "IO," as appropriate. Carrier must obtain an Authorization code for all such Card Transactions. If a Carrier or Agent completes a Transaction without imprinting of the Card or using a Terminal, Carrier shall be deemed to warrant the true identity of the Cardholder as the authorized holder of such Card unless

9

[6.2.36] [U.S. Bank - Signatory Agreement.pdf]

Carrier or Agent has obtained independent evidence of the Cardholder's true identity and has noted such evidence on the applicable Sales Record.

POS Devices are prohibited from printing or displaying more information than that which is permitted by Operating Regulations and applicable laws and regulations.

Carrier may, at its option, pursue payment from the customer outside the Card Association system. Should Carrier exercise this option and the Cardholder acknowledge the debt, and choose to pay the amount in full using its Card, Carrier may present a Sales Record in such amount to Servicer for processing.

(d) Carrier or Agent shall submit to Servicer for processing each Sales Record in accordance with the timeframes required by the applicable Operating Regulations. The method of billing for all Electronic Sales Records and Electronic Credit Records processed through any Billing Settlement Processor must be by electronic transmission and shall include itinerary records consisting of departure dates. If Carrier is unable to submit Sales Records and Credit Records originating at Carrier's sales locations, including airport locations, ticket-by-mail centers, and other sales locations, by means of a summary electronically transmitted as provided in Sections 6.5 and 7.1, Carrier may submit such Sales Records and Credit Records to Servicer by means of a paper summary and detail thereof to Servicer's designated processing center, or by means of a Terminal that generates an electronic transmission to Servicer's designated Terminal processor.

(e) Member or Servicer will deposit, or cause to be deposited, on each Business Day, via federal wire transfer, in the case of U.S. dollar Transactions, and SWIFT, in the case of Canadian dollar Transactions, into the applicable Settlement Account for each applicable currency, an amount equal to the amount of Net Activity relating to such currency for each Business Day, subject to Servicer's receipt of the incoming transmission of Sales Records and Credit Records by the time and on the day specified in Exhibit A.

(f) At any time that the aggregate amount of Net Activity results in an amount due Member or Servicer, the aggregate amount due to each of them may be deducted, recouped or set off from amounts subsequently payable to Carrier under this Agreement on account of Sales Records irrespective of the currency in which payment to Carrier is to be made; provided, that, Member or Servicer may, at its option (i) require an immediate wire transfer from Carrier in the amount due, or (ii) apply, set off against or recoup from any Deposit amount maintained pursuant to this Agreement the amount due from Carrier under this Agreement. Carrier will, upon demand by Member or Servicer, pay interest on the amount due from Carrier under this Agreement for the period such amount remains unpaid calculated at a per annum rate equal to the Applicable Rate. Carrier acknowledges that this Agreement is a "net payment agreement" and that the right of Member or Servicer to net out obligations due from Carrier under this Agreement from amounts payable to Carrier hereunder (including from or as represented by the Deposit amount) is a right of recoupment. Carrier further acknowledges that Member and Servicer have entered into each Agreement in reliance upon such right.

(g) Amounts deposited in a Settlement Account or otherwise credited to Carrier (including, without limitation, amounts credited against Carrier's obligations to Member or Servicer for fees, costs and expenses hereunder) in respect of any Sales Record pursuant to this Agreement and Carrier's right to payment of Reserved Funds

14

[6.2.36] [U.S. Bank - Signatory Agreement.pdf]

shall be provisional until the payment made to Member by the Card Association in respect of such Sales Record shall become final (i.e., all rights of Chargeback or other rights of the Cardholder or Card issuer to obtain reimbursement of such payment from Member shall have expired).

(h) Submissions and payment from any location must be handled in compliance with all applicable government laws, rules and regulations.

(i) The Signatory Agreement that is part of this Agreement may specify the location of the originating source of submission of any file.

6.3 Processing fees shall be as set forth in the Fee Schedule attached to the Signatory Agreement that is part of this Agreement.

6.4 Servicer will provide Carrier with Transaction reports each Business Day that correspond to Net Activity for such Business Day and that will summarize sales, returns (refunds), Chargebacks, processing fees, and adjustments with adequate detail to allow Carrier to perform account reconciliation.

6.5 Carrier shall cause Agents to submit Electronic Sales Records and Electronic Credit Records to Servicer in the form of the Settlement File by electronic transmission as provided in Sections 6.2(d) and 7.1 through Carrier's accounting office or the appropriate processing center of the area or Billing Settlement Processor of which Carrier is a member. Carrier or the appropriate processing center, as the case may be, shall submit the Electronic Sales Records and Electronic Credit Records to Servicer in accordance with the terms of the Agreement.

6.6 If Carrier utilizes Electronic Data Capture services pursuant to this Section 6.6 to transmit Electronic Sales Records and Electronic Credit Records for Card Transactions through a Terminal, Carrier agrees to utilize such EDC services in accordance with applicable Operating Regulations. Carrier may designate a third person as its agent to deliver to Servicer or directly to Card Associations Transactions captured at the point of sale by such agent. If Carrier elects to designate such an agent, Carrier must provide Servicer prior written notice of such election. Carrier understands and agrees that Member or Servicer is responsible to make payment to Carrier for only those Transaction amounts delivered by such agent to the Card Associations, less amounts withheld by Member or Servicer pursuant to the Agreement, and Carrier is responsible for any failure by such agent to comply with any Operating Regulations, including any such failure that results in a Chargeback.

SECTION 7. ELECTRONIC TRANSMISSION.

7.1 (a) When Electronic Sales Records and Electronic Credit Records are submitted to Servicer electronically, other than Electronic Sales Records and Electronic Credit Records originating from Terminals, as provided in Section 6.6, and processed by Servicer's Terminal processor, such Electronic Sales Records and Electronic Credit Records shall be submitted to Servicer by means of a summary of all Travel Costs by electronic transmission compatible with the computer system of Servicer and shall comply with Section 6.2 of the Agreement. Each such electronic transmission shall contain, at a minimum, the information required for each Electronic Sales Record by Section 3.7 and shall be made in the form of the Settlement File or any other format acceptable to Servicer in its sole discretion, provided, however, that (i) Carrier will not change the format of such electronic submissions

15

[6.2.36] [U.S. Bank - Signatory Agreement.pdf]

without first obtaining Servicer's consent, which consent shall not be unreasonably withheld or delayed and (ii) if Carrier requests a change in format with respect to such electronic submissions, Servicer may test such electronic submissions (in the requested format) prior to consenting to such change in format, and such testing by Servicer shall not constitute consent to such format change and shall not in any way limit Servicer's right to reasonably withhold consent with respect to such format change.

(b) If an electronic transmission of Travel Costs does not meet the requirements of the approved format, Servicer shall use reasonable efforts to advise Carrier within eight hours of receipt of same.

(c) Any acceptance by Servicer of an electronic transmission of Travel Costs which does not comply with the appropriate format or, if in the appropriate format, does not contain the information in respect to each Travel Cost summarized therein required by the terms of the Agreement, shall not constitute a waiver of, or preclude Member or Servicer from exercising, the right of Chargeback.

7.2 Carrier shall retain, or cause to be retained, each original Sales Record and Credit Record and any other documentation necessary for Member or Servicer to satisfy applicable Operating Regulations ("Retained Documents") relating to those Transactions transmitted to Servicer directly by Carrier, in each case for at least eighteen (18) months from the date each such Retained Document is submitted to Servicer for processing. Promptly upon Carrier's receipt of Servicer's request for the same, but in no event later than fourteen (14) calendar days following Carrier's receipt of such request, Carrier shall deliver, or cause to be delivered, to Servicer a copy, or the original if specifically requested by Servicer, of the requested document.

Notwithstanding the foregoing, either Carrier or Servicer may elect to hold in its custody Retained Documents for no more than 180 days provided such Party retains a microfilmed or microfiched (or other mutually acceptable medium) copy of such documents for at least eighteen (18) months from the date on which each such document is submitted to Servicer for processing.

SECTION 8. CHARGEBACKS.

8.1 Neither Member nor Servicer is obligated to accept any Sales Record which does not comply in every respect with the terms and conditions of this Agreement, or which does not comply in all respects with the applicable Operating Regulations.

8.2 Carrier agrees to pay Member (or if notified by Servicer to do so, to pay Servicer) the amount of each Chargeback and, in the case of amounts that have not been paid to Carrier, acknowledges Carrier has no right to receive amounts attributable to Chargebacks. Member or Servicer may deduct and retain any amount due to Member or Servicer from Carrier on account of Chargebacks from amounts otherwise payable to Carrier under this Agreement. The provisions of Section 6.2 with respect to payment of Carrier's obligations to Member and Servicer will apply in the event the amount of Net Activity results in an amount due Member or Servicer.

8.3 So long as a Chargeback claim is in the process of dispute resolution pursuant to the Operating Regulations, Carrier shall not make any other claim or take any proceedings

16

[6.2.36] [U.S. Bank - Signatory Agreement.pdf]

against the Cardholder in relation to the related Card Transaction or the underlying contract of sale or service.

8.4 In connection with the processing of Chargeback claims, Servicer and Member shall be entitled to rely and act on any agreements, requests, instructions, permissions, approvals, demands or other communications given on behalf of Carrier (whether via email or otherwise in writing) and Servicer shall not be liable to Carrier for any loss or damage incurred or suffered by it as a result of such action.

27

[6.2.36] [U.S. Bank - Signatory Agreement.pdf]

to other potential parties to such dealings or transactions or their professional advisors, subject to confidentiality agreements no less protective than these confidentiality provisions, (iii) in connection with the enforcement of the rights of Member or Servicer hereunder or otherwise in connection with applicable litigation, and (iv) as may otherwise be required by any court or law enforcement or regulatory authority having jurisdiction over Member or Servicer or by any applicable law, rule, regulation or judicial process, the opinion of legal advisors to Member or Servicer concerning the making of such disclosure to be binding on the parties hereto; provided, that in the event that Member or Servicer determines that it is required to disclose any such information whether pursuant to a judicial order or to applicable law, Member or Servicer, as applicable, to the extent legally permissible, agrees to provide Carrier with ten (10) days' prior written notice (or such shorter prior notice as shall be reasonable and practicable in the circumstances) of such determination and the basis for such determination prior to making disclosure so that Carrier may consider whether to seek an appropriate protective order or to waive compliance with the requirements of this Section 24.

SECTION 26. ASSOCIATION OBLIGOR.

For the avoidance of doubt, it is understood and agreed that in the case of any such obligation, Carrier shall only be obligated to pay the obligation once, unless payment is made to an entity other than Member, Servicer, an Association Obligor, Card Association or other Secured Party, and the obligation to the Card Association is not extinguished or satisfied on account of such payment or otherwise. Member or Servicer shall act reasonably on behalf of an Association Obligor in such circumstances and Carrier may rely upon any actions taken or directions given by Member or Servicer as having been authorized by an Association Obligor.

If Carrier fails to pay a judgment as described in the preceding sentence, Carrier agrees to indemnify Member and Servicer against any loss incurred by Member or Servicer as a result of the rate of exchange at which any amount recovered against Carrier (by way of recoupment, setoff or otherwise) is converted to the Judgment Currency. The foregoing indemnity shall constitute a separate and independent obligation of Carrier and shall apply irrespective of any indulgence granted to Carrier from time to time and shall continue in full force and effect notwithstanding any such judgment or order as aforesaid. The term "rate of exchange" shall include any premiums and costs of exchange payable in connection with the purchase of, or conversion into, the relevant currency.

SECTION 28. WAIVER OF SOVEREIGN IMMUNITY.

2. Exposure Protection

(a) Upon commencement of the Agreement, Member or Servicer may retain and hold all funds paid to Member by a Card Association on account of Sales Records submitted by Carrier to Servicer or Member as Reserved Funds until the amount of the Aggregate Protection equals the Required Amount, as determined in accordance with Sections 3 and 8 of this Exposure Protection Schedule.

The Deposit amount shall be

(U.S. Transactions)

44

[6.2.36] [U.S. Bank - Signatory Agreement.pdf]

subject to adjustment as provided in Section 3 of this Exposure Protection Schedule. Member, Servicer or any Secured Party will hold the Deposit as security for the due and punctual payment of and performance by Carrier of the Obligations.

(b) To the extent Carrier has or may at any time acquire any rights in Carrier's Rights, Carrier grants to each of Servicer, Member, and all other Secured Parties a Lien on the Deposit and all other Carrier's Rights to secure the payment and performance by Carrier of all Obligations. Each Secured Party shall act as agent for all Secured Parties to the extent that any such Secured Party controls or possesses the Deposit or any collateral hereunder or is named as Secured Party on any filing, registration or recording. Carrier hereby acknowledges that notwithstanding the foregoing grant of a Lien, Reserved Funds represent only a future right to payment owed to Carrier under the Agreement, payment of which is subject to the terms and conditions of the Agreement and to Carrier's complete and irrevocable fulfillment of its obligations and duties under the Agreement and do not constitute funds of Carrier.

(c) Carrier further agrees that during the term of the Agreement, Carrier shall not grant, or attempt to grant, to any other Person or suffer to exist in favor of any other Person any Lien or other interest in Carrier's Rights (if any) or in any proceeds thereof unless any such Lien or other interest and the priority thereof are subject to a subordination agreement in favor of Member, Servicer and all other Secured Parties and reasonably satisfactory to Servicer. This prohibition against the granting of any liens does not include a prohibition against the granting of liens in Carrier's right to payment under this Agreement from Member or Servicer after Member or Servicer has setoff any amounts that may be owing from Carrier to Member or Servicer under this Agreement (a "Right to Payment") and Member and Servicer acknowledge that they have received notice that Carrier has granted a lien in its Right to Payment in favor of Goldman Sachs Credit Partners LP ("Goldman") and certain other lenders pursuant to that certain Security Agreement and Chattel Mortgage, dated as of July 25, 2005, between Carrier and Wells Fargo Bank Northwest, National Association, as collateral agent on behalf of Goldman (the "Goldman Lien")

(d) Carrier hereby acknowledges that Member and Servicer dispute the existence of any interest of Carrier in any rights to payment from Cardholders or Card Issuers arising out of the Sales Records and further acknowledges that to the extent it may have an interest therein, such interest is subordinate to the interests of the Secured Parties and of any of their respective subrogees.

(e) Carrier will do all acts and things, and will execute, endorse, deliver, file, register or record all instruments, statements, declarations or agreements (including pledges, assignments, security agreements, financing statements, continuation statements, etc.) reasonably requested by Servicer, in form reasonably satisfactory to Servicer, to establish, perfect, maintain and continue the perfection and priority of the security interest and hypothec of Secured Parties in all Carrier's Rights and in all proceeds of the foregoing, as granted by Carrier pursuant to Section 2(b) and 2(d) of this Exposure Protection

(U.S. Transactions)

45

[6.2.36] [U.S. Bank - Signatory Agreement.pdf]

Schedule. Carrier will pay the reasonable costs and expenses of all filings and recordings, including taxes thereon or fees with respect thereto and all searches reasonably necessary or deemed necessary by Servicer, to establish and determine the validity and the priority of such security granted in favor of Servicer. Carrier hereby irrevocably appoints Servicer (and all persons, officers, employees or agents designated by Servicer), its agent and attorney-in-fact to do all such acts and things contemplated by this paragraph in the name of Carrier. Without limiting the foregoing, Carrier hereby authorizes Servicer to file one or more financing statements or continuation statements in respect hereof, and amendments thereto, relating to any part of the collateral described herein without the signature of Carrier. A carbon, photographic or other reproduction of the Agreement or of a financing statement shall be sufficient as a financing statement and may be filed in lieu of the original in any or all jurisdictions which accept such reproductions.

3. Adjustments to Deposit

(a) Servicer will use the Methodology described in Section 8 of this Exposure Protection Schedule (the "Methodology") to calculate Gross Exposure each Business Day. Carrier acknowledges that Servicer has explained to it and it understands Servicer's Methodology for determining Gross Exposure and the amount of the Aggregate Protection and hereby agrees to be bound by such Methodology and the determinations made by Servicer as a result thereof, absent manifest error. Among other things, Carrier understands that Gross Exposure includes the value of Travel Costs for goods or services sold to Cardholders who used their Cards to purchase such goods or services with respect to which Carrier has not yet provided such goods or services. Servicer and Carrier may change the Methodology by mutual agreement.

(b) The amount of the Deposit shall be increased or decreased each Business Day, as appropriate, based on the Methodology so that the amount of the Aggregate Protection will at all times equal the Required Amount. Any necessary increases to the Deposit may be made, at Servicer's sole discretion by Member or Servicer withholding as Reserved Funds an amount up to [***] of amounts otherwise payable to Carrier under Section 6.2 of the MTOS until the amount of the Aggregate Protection is at least equal to the Required Amount, or by federal wire transfer of immediately available funds from Carrier to an account designated by Servicer, on the first (1st) Business Day after Carrier's receipt of notice from Servicer that an increase is required and the amount thereof. If the Servicer agrees to permit increases to the amount of the Deposit by wire transfer and the funds required to increase the amount of the Deposit so that the Aggregate Protection is equal to the Required Amount are not transferred to Servicer as required by this Section 3, Member or Servicer may immediately withhold on a daily basis as Reserved Funds an amount up to [***] of amounts otherwise payable to Carrier under Section 6.2 of the MTOS until the amount of the Aggregate Protection at least equals the Required Amount. Member or Servicer shall remit to Carrier from the Deposit the amount necessary to reduce the amount of the Aggregate Protection to equal the Required Amount on each Business Day in accordance with Section 6.2 of the MTOS.

(U.S. Transactions)

46

[6.2.36] [U.S. Bank - Signatory Agreement.pdf]

(c) The amount of the Deposit to be maintained hereunder may be reduced in accordance with Section 9 of this Exposure Protection Schedule pursuant to which Servicer accepts Letter of Credit in lieu of all or a portion of the Deposit so long as the Aggregate Protection equals the Required Amount. Similarly, Servicer shall accept a Letter of Credit meeting the terms contained herein in replacement of an existing Letter of Credit that is either (i) within 120 days of expiration or (ii) may, after the expiration of the appropriate time frame set forth in Section 9, be subject to a draw due to a downgrade of the bank that issued such Letter of Credit.

(d) Although Servicer has the right at all times to require that the amount of the Aggregate Protection equal the Required Amount, Servicer may, from time to time, in its sole discretion make remittances to Carrier or release portions of any Letter of Credit such that the Aggregate Protection is less than the Required Amount. The duration of any such reduction is within the sole discretion of Servicer. At any time that the amount of the Aggregate Protection is less than the Required Amount Servicer, in its sole discretion, may again require that the amount of the Aggregate Protection equal the Required Amount. Any required increase may be made as provided in Section 3(b) of this Exposure Protection Schedule as determined by Servicer. Any reductions in the amount of the Aggregate Protection as described in this paragraph shall not be deemed a course of dealing nor give rise to any rights by Carrier in the future to require that the amount of the Aggregate Amount be less than the Required Amount.

(e) If an event or series of events occurs that can reasonably be determined to have a materially positive effect on Carrier's present and prospective financial condition, then within ten days of each anniversary date of the Commencement Date Carrier may submit a written request to Servicer to review the Required Amount for consideration of a reduction in the percentage of Gross Exposure required to be maintained as the amount of the Aggregate Protection (a "Modification Request"). Servicer shall review the Modification Request and information presented by Carrier and attempt to respond to such request within thirty (30) days. Any determination of whether to agree to the Modification Request shall be made in the sole discretion of Servicer. If Servicer does not agree to the Modification Request, then Carrier shall have a period of fifteen (15) days from such response by Servicer to provide written notice to Servicer of Carrier's election to terminate the Agreement ninety days from the date Carrier's notice to terminate is delivered to Servicer. Carrier shall have no right to terminate the Agreement prior to its then current term (other than as a result of Servicer or Member's breach) if it fails to (i) deliver a Modification Request within the time frame stated in this Section or (ii) provide notice of termination as a result of a negative response by Servicer to a Modification Request within the time frame stated in this Section.

4. Control of Deposit

Carrier acknowledges that (i) funds remitted to Member or Servicer by Carrier and (ii) funds paid by Card Associations and held by Member, Servicer or any Secured Party as the Deposit may be commingled with other funds of Member, Servicer or

(U.S. Transactions)

47

[6.2.36] [U.S. Bank - Signatory Agreement.pdf]

such Secured Party, and further acknowledges that all such funds, and any investment of funds shall be in the name and control of Member, Servicer or such Secured Party, and Carrier shall have no interest in any securities, instruments or other contracts or any interest, dividends or other earnings accruing thereon or in connection therewith. It is the understanding of the Parties that, notwithstanding any other provision of the Agreement to the contrary, (a) the sole obligation of Member or Servicer with respect to the Deposit shall be the obligation to pay to Carrier amounts equal to the amounts attributable to Travel Costs with respect to which Carrier has provided goods or services net of any Obligations owed Carrier to any Secured Party, (b) such obligation to make payment to Carrier is at all times subject to the terms of the Agreement, and (c) such payment shall only be due and payable upon complete and irrevocable fulfillment by Carrier of all of its obligations and duties under the Agreement.

5. Investment

(a) To the extent permitted by applicable law or regulation, all amounts held as the Deposit will be deemed to earn a yield equal to the Applicable Rate. The amount so earned shall be credited to the Deposit.

6. Right of Offset; Recoupment; Application

At any time that an amount is due Member, Servicer or any other Secured Party from Carrier, and Member, Servicer or such other Secured Party does not obtain payment of such amount due as provided in the Agreement, Member or Servicer (each on behalf of itself and any other Secured Party) shall have the right to apply, recoup or set off any amounts otherwise owed by Member, Servicer or any other Secured Party to Carrier hereunder, including, without limitation, any amounts attributable to the Deposit, to the amount owed by Carrier. Servicer may exercise any such right for its benefit or the benefit of Member or any other Secured Party. Where any application, recoupment or set off requires the conversion of one currency into another, Servicer or Member shall be entitled to effect such conversion in accordance with its prevailing practice and Carrier shall bear all exchange risks, losses, commissions and other bank charges which may thereafter arise.

7. Retention of Deposit After Cessation

Notwithstanding any other provision of the Agreement to the contrary, during the period not to exceed [***] months from the earlier of termination of this Agreement or the date upon which Carrier permanently ceases flight operations, Member and Servicer may retain the Deposit and Letters of Credit so that the Aggregate Protection at least equals the Required Amount on each day. As the Required Amount is reduced because Gross Exposure has been reduced, Servicer is obligated to remit sufficient funds from the Deposit and/or return the Letter of Credit to Carrier within two (2) business days of such determination so that the Aggregate

Protection does not exceed the Required Amount. Subject to the foregoing and the eighteen month time frame, Servicer shall continue to hold the Deposit and/or Letters of Credit until Servicer has determined that Carrier has no further Obligations or potential Obligations and Servicer shall be without any obligation to remit funds to Carrier until such time.

9. Standby Letter of Credit

(a) The amount of the Aggregate Protection which Servicer or Member may maintain pursuant to this Exposure Protection Schedule shall include the sum of (a) the amount remaining to be drawn upon any valid and outstanding Letter of Credit and (b) the proceeds of any previous draw on a Letter of Credit held by Servicer or Member and not applied. At such time as the Servicer or Member may no longer draw on the Letters of Credit, Servicer may require that the amount of the Deposit plus proceeds of any draw on the Letters of Credit held by Servicer or Member and not applied equal the Required Amount.

(b) Upon the occurrence of any event that gives rise to Servicer's right under this Agreement to make demand on Carrier for payment to Servicer or Member of any Obligations and after (i) application of all amounts held as part of the Deposit and (ii) application of all amounts that would otherwise be payable to Carrier from Member or Servicer under the Agreement on such date, if any, then the Servicer, at its option, may draw on any Letter of Credit issued for its benefit with respect to the Agreement to pay such Obligations in an amount that does not exceed the sum of (A) the amount the Servicer has a right to demand that the Carrier pay the Servicer or Member under this Agreement on such date plus (B) the amounts the Servicer reasonably believes it will have a right to demand that the Carrier pay the Servicer or Member as Obligations during the following seven day period.

(c) Notwithstanding anything to the contrary contained in this Section 9 to the contrary, Servicer may draw upon the full amount of a Letter of Credit if sixty (60) days have passed since Servicer delivered written notice to Carrier that

the rating of the bank that issued the Letter of Credit has fallen below (A) [***] under the Moody's Investors Service rating system or (B) [***] under the Standard and Poor's rating system, or (C) if ratings from either of those services are unavailable, the equivalent rating of any of the foregoing under any similar rating system.

(d) Notwithstanding anything to the contrary contained in this Section 9 to the contrary, Servicer may draw upon the full amount of a Letter of Credit if (i) five (5) Business Days have passed since the rating of the bank that issued the Letter of Credit has fallen below (A) [***] under the Moody's Investors Service rating system or (B) [***] under the Standard and Poor's rating system, or (C) if ratings from either of those services are unavailable, the equivalent rating of any of the foregoing under any similar rating system, (ii) an Insolvency Proceeding is commenced by or against Carrier or (iii) the Letter of Credit is set to expire within 60 days and Servicer has not received notice of renewal of the Letter of Credit or an replacement letter of credit acceptable as to form and issuer in the sole discretion of Servicer.

(e) Carrier acknowledges that subject to its right to receive payments under this Agreement, it has no interest in any proceeds of any draw on any Letter of Credit issued for the benefit of Servicer or Member and that upon any valid draw on any Letter of Credit, Servicer or Member shall be entitled to hold the proceeds thereof for payment of the Obligations under the Agreement and apply such proceeds in payment thereof as and when Servicer reasonably deems appropriate, subject to the provisions of Section 7 of this Exposure Protection Schedule. Neither Servicer nor Member shall have any obligation to remit to any Person any excess proceeds of any draw on any Letter of Credit until expiration of the period specified in Section 7 of this Exposure Protection Schedule. In the event of any dispute between Carrier and the issuer of a Letter of Credit or any subrogee thereof, or any other Person with respect to entitlement to any proceeds of a Letter of Credit, Servicer or Member may retain all such proceeds until final resolution of such dispute by a court of competent jurisdiction, subject to the right of Servicer or Member to retain and apply proceeds in payment of the Obligations. In the event that Servicer or Member draws on a Letter of Credit and holds the proceeds thereof at a time when Carrier is conducting normal flight operations, Servicer or Member, at its option, may include such proceeds in its calculation of coverage for the Required Amount and remittances to Carrier may be made in accordance with Section 2 of this Exposure Protection Schedule as if the proceeds were part of the Deposit. Carrier further agrees that at Servicer's option, any excess proceeds of a Letter of Credit, as determined by Servicer in good faith after taking into account all obligations of the Carrier to the Secured Parties, may be remitted to the issuer of a Letter of Credit, or if the issuer has been reimbursed in full for all amounts owed to it on account of the draw on the Letter of Credit, to the account party thereof.

10. Fare Club Exposure

(a) The "Fare Club Exposure," as determined in accordance with this Section 10 shall be added to the calculation of Gross Exposure at all times; provided,

(U.S. Transactions)

51

[6.2.36] [U.S. Bank - Signatory Agreement.pdf]

however, (i) the Fare Club Exposure will first be added to the calculation of Gross Exposure on the last Business Day of the first full month after the Commencement Date and (ii) the amount of the Fare Club Exposure will only be modified as of the last Business Day of each month.

(b) The initial calculation of the Fare Club Exposure shall be based upon the assumption that (i) the Fare Club memberships are only for a [***] period and (ii) sales of Fare Club membership average [***] per month.

(c) During the initial six month period beginning with the first full month after the Commencement Date, the following amounts shall constitute the Fare Club Exposure:

Month No.	1	2	3	4	5	6
Fare Club Exposure Amount	[***]	[***]	[***]	[***]	[***]	[***]

(d) Within 10 days of the end of each month, Carrier shall provide Servicer with a report of its Fare Club membership sales for the preceding month made through the use of a Card (the "Fare Club Sales Report"). The first Fare Club Sales Report shall cover the first full calendar month after the Commencement Date.

(e) At the conclusion of each six month period, Servicer shall complete a reconciliation between the actual Fare Club Exposure then held and the actual exposure based upon the Fare Club Sales Reports (the "Reconciled Exposure"). The actual exposure for determining the Reconciled Exposure shall be determined by taking the fare club sales for any particular month and reducing such amount by [***] of the original monthly sale amount in each month after such sale until the amount reaches zero, with the first [***] reduction occurring in the month the fare club sale occurs (the "Exposure Reduction Methodology"). Based upon such reconciliation, the amount of Fare Club Exposure will modified to be equal to the Reconciled Exposure.

(f) During each successive six month period, the Fare Club Exposure will be determined by (i) using the most recent Reconciled Exposure and reducing such amount in each successive month in accordance with the Exposure Reduction Methodology and (ii) adding to the Fare Club Exposure each month an amount equal to the average monthly amount of fare club sales as determined by the most recent six Fare Club Sales Reports, but subtracting from the Fare Club Exposure an amount determined by applying the Exposure Reduction Methodology in succeeding months to the amounts added to the Fare Club Exposure.

(g) Servicer reserves the right to modify the Fare Club Exposure to the extent that Carrier sells fare club memberships with a term longer than one year. Carrier may request that Servicer adjust the calculation of Fare Club Exposure if at any time more the 40% of the fare club memberships then outstanding, when originally sold, were for terms materially shorter than one year.

FIRST AMENDMENT TO SIGNATORY AGREEMENT

THIS FIRST AMENDMENT TO SIGNATORY AGREEMENT (this "Amendment") is entered into as of January 18 , 2010, by and between Spirit Airlines, Inc., a company organized under the laws of the state of Delaware ("Carrier"), and U.S. Bank National Association ("Bank").

RECITALS

A. Bank and Carrier are parties to a Signatory Agreement (U.S. VISA and MasterCard Transactions) dated as of May 21, 2009 (as the same has been amended, restated or otherwise modified from time to time, the "Card Processing Agreement") pursuant to which Bank processes certain payments made to Carrier using Cards (as such term is defined in the Card Processing Agreement) bearing the servicemark of Visa International, Visa U.S.A. Inc. or MasterCard International Incorporated.

B. Carrier and Bank each desire to make certain changes to the Card Processing Agreement and have therefore agreed to enter into this amendment.

AGREEMENT

NOW, THEREFORE, for good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties hereto hereby covenant and agree to be bound as follows:

Section 1. Capitalized Terms. Capitalized terms used herein and not otherwise defined herein shall have the meanings assigned to them in the MTOS attached to the Card Processing Agreement, unless the context shall otherwise require.

Section 2. Amendments. The Card Processing Agreement is hereby amended to add a new Section 16 to the Signatory Agreement portion of the Card Processing Agreement to read as follows:

Section 16 Internet Debit Card Processing. Notwithstanding anything else contained in this Agreement, Carrier may submit for processing hereunder PIN-based Internet Transactions involving Debit Cards provided Bank has notified Carrier that Bank or its affiliates agrees to accept such Transactions. Cartier understands and agrees that Bank's ability to accept PIN-based Internet Debit Card Transactions under this Agreement is dependent upon Bank or its affiliate having agreements in place with certain third party vendors, such as Acculynk. Carrier acknowledges that even if Bank agrees to accept PIN-based Internet Debit Card Transactions, Bank may not be able to accept Transactions for Debit Cards on all the EFT Networks. Carrier may not submit any other PIN-based Debit Card Transactions under this Agreement other than PIN-based Internet Debit Card Transactions. If Bank can no longer process PIN-based Internet Debit Card Transactions because it does not have the required enforceable contracts with third party vendors, no such Transactions may be submitted hereunder. Bank shall not be deemed in breach of the Agreement or otherwise have any liability to Carrier as a result of its inability to process PIN-based Internet Debit Card Transactions due to the lack of the required contracts with third party vendors.

During any period in which Bank can accept PIN-based Internet Debit Card Transactions, the following additional terms shall apply:

16.1 Section 1 of the MTOS is hereby amended by adding the following definitions in the correct alphabetical order:

Credit Card Associations - Visa U.S.A. Inc., Visa International, Inc., MasterCard International Incorporated and any other national card association designated by Bank.

Debit Card - A card or device bearing the symbol(s) of one or more EFT Networks or Credit Card Associations, which may be used to purchase goods and services from Carrier and to pay the amount due to Carrier by an electronic debit to the Cardholder's designated deposit account.

EFT Networks - (i) Interlink Network, Inc., Maestro U.S.A., Inc., STAR Networks, Inc., NYCE Payments Network, LLC, PULSE Network LLC, ACCEL/Exchange Network, Alaska Option Services Corporation, Armed Forces Financial Network, Credit Union 24, Inc., NETS, Inc. and SHAZAM, Inc. and (ii) any other organization or association that hereinafter authorizes Bank or its affiliates to authorize, capture, and/or settle Transactions effected with Debit Cards, and any successor organization or association to any of the foregoing.

Internet PIN Pad - A secure program that displays and allow entry on an alphanumeric keyboard which conforms with the Operating Regulations and requirements established from time to time by Bank, and through which a Cardholder may enter a PIN.

PIN - A Personal Identification Number.

16.2 The definitions of "Card" and "Card Associations" contained in Section 1 of the MTOS are amended and restated in their entirety to read as follows:

Card - (i) Any card (other than a Debit Card) with respect to MasterCard International Incorporated, Visa U.S.A., Inc. or Visa International or other cards bearing the service mark of MasterCard International Inc., Visa U.S.A., Inc. or Visa International or any other national card association designated by Bank and (ii) any Debit Card.

Card Associations - The Credit Card Associations and the EFT Networks and any other card association that may in the future be designated by mutual agreement of Bank and Carrier.

16.3 Fees for PIN-based Internet Debit Card Transactions shall be based upon Debit Card Fee Schedule to the Agreement, attached as Exhibit A to the First Amendment to Signatory Agreement, and the Fee Schedule attached to the Agreement shall not apply to such PIN-based Internet Debit Card Transactions.

16.4 If requested by Bank or required by any EFT Network, Carrier shall prominently display the most current versions of the EFT Network's names, symbols, and/or service marks, as appropriate, on its Internet website and may display such

2

marks on promotional materials to inform the public that such Debit Cards will be honored by Carrier. Carrier's use of such marks must comply with the requirements of each mark's owner. Carrier's right to use or display such marks shall continue only long as the Agreement remains in effect and such right shall automatically terminate upon termination of the Agreement.

16.5 In submitting PIN-based Internet Debit Card Transactions to Bank, Carrier agrees as follows:

a. A Cardholder's Debit Card information and PIN are confidential.

b. During the Transaction process, Carrier will employ an Internet PIN Pad with appropriate technology to maintain the confidentiality of the Cardholder's Debit Card information and PIN.

c. Carrier shall use appropriate technology when initiating every Debit Card Transaction so as to prevent the unauthorized recording or disclosure of a Cardholder's PIN.

d. Carrier shall require that each holder of a Debit Card enter his or her PIN on a Internet PIN Pad when initiating a PIN-based Internet Debit Card Transaction.

16.6 Carrier shall support PIN-based Internet Debit Card Transactions for purchases and refunds, but may not support purchases with cashback or balance inquiries.

16.7 At the time of any PIN-based Internet Debit Card Transaction, Carrier shall make available for each Cardholder to print a Transaction receipt containing, at a Minimum, the following information:

• Amount of the Debit Card Transaction,

• Date of the Debit Card Transaction,

• Truncated Debit Card number or another account number or code that uniquely identifies the Cardholder,

• Carrier's name, and

• Reference number or authorization number.

16.8 Carrier may electronically perform a refund Transaction (if permitted by the applicable EFT Network) for a PIN-based Internet Debit Card Transaction only if original PIN-based Debit Card Transaction was initiated by Carrier.

16.9 When requested by any EFT Network, in its sole discretion, Carrier will immediately take action to: (i) eliminate any fraudulent or improper Transactions, (ii) suspend processing of PIN-based Internet Debit Card Transactions; or (iii) entirely discontinue acceptance of PIN-based Internet Debit Card Transactions.

16.10 Carrier understands that PIN-based Internet Debit Card Transactions conducted with a Internet PIN Pad are high risk and there is a significant risk that a Cardholder's PIN may be tracked or improperly disclosed if appropriate security technology is not employed with the Internet PIN Pad. Carrier understands that Bank

3

does not provide such security technology and that it is solely Carrier's responsibility to employ such technology. Carrier indemnifies Bank against any claims made by a holder of a Debit Card regarding the unauthorized disclosure of such Cardholder's PIN in any Transactions submitted to Bank for processing.

16.11 All PIN-based Internet Debit Card Transactions shall be included in the flight calendar under the Exposure Protection Schedule to the Agreement and otherwise included when determining Gross Exposure. Carrier shall be responsible for submitting to Bank the flight data information for each PIN-based Internet Debit Card Transaction necessary to allow Bank to include such Transactions in the Gross Exposure calculation.

16.12 Carrier recognizes that the rules for Chargebacks on PIN-based Internet Debit Card Transactions under the EFT Networks and applicable law may differ from the rules applicable to transactions under the Credit Card Associations and agrees that any rules contained under this Agreement applicable to Chargebacks shall be deemed modified to account for such differences under the EFT Networks and applicable law.

Section 3.Representations and Warranties of Carrier. Carrier hereby represents and warrants to Bank that on and as of the date hereof and after giving effect to this Amendment:

3.1 All of Carrier's representations and warranties contained in the Card Processing Agreement are true, correct and complete in all respects as of the date hereof as though made on and as of such date; provided, that references in Section 9.1(e) of the MTOS to financial statements shall be to the most recent financial statements of such type delivered to Bank by Carrier.

3.2 Carrier has the power and legal right and authority to enter into this Amendment and has duly authorized as appropriate the execution and delivery of this Amendment and none of the agreements contained herein contravene or constitute a default under any agreement, instrument or indenture to which the Carrier is a party or a signatory or a provision of Carrier's Certificate or Articles of Incorporation or, to the best of the Carrier's knowledge, any other agreement or requirement of law, or result in the imposition of any lien on any of its property under any agreement binding on or applicable to Carrier or any of its property except, if any, in favor of Bank.

3.3 Carrier is duly organized and in good standing under the laws of the state of its organization and is qualified to do business in each state where the nature of its activities or the character of its properties makes such qualification necessary or desirable and the failure to so qualify would have a material adverse effect on the assets or operations of Carrier.

3.4 Upon the effective date of this Amendment, this Amendment and the Card Processing Agreement, as supplemented and amended hereby, will constitute the legal, valid and binding obligations of Carrier enforceable in accordance with their terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium and other laws affecting the rights of creditors generally, and to the exercise of judicial discretion in accordance with general principles of equity.

4

Section 4. Representations and Warranties of Bank. Bank represents and warrants to Carrier that Bank has full and complete power and authority to enter into and perform under this Amendment and has obtained, and there remain in effect, all necessary licenses, resolutions and filings which are necessary for Bank to perform its obligations under this Amendment.

Section 5. Ratification of Agreement; Acknowledgment. Except as expressly modified under this Amendment, all of the terms, conditions, provisions, agreements, requirements, promises, obligations, duties, covenants and representations of Carrier and Bank, respectively, under the Card Processing Agreement are hereby ratified by Carrier and Bank, respectively. All references contained in the Card Processing Agreement and the Schedules thereto to "Agreement" shall mean the Card Processing Agreement as supplemented and amended hereby.

Section 6. Effective Date. This Amendment shall become effective upon execution and delivery to Bank of duly executed counterparts hereof by Bank and Carrier.

Section 7. Merger and Integration, Superseding Effect . This Amendment, from and after the date hereof, embodies the entire agreement and understanding between the parties hereto, and supersedes and has merged into it all prior oral and written agreements, on the same subjects by and between the parties hereto with the effect that this Amendment shall control with respect to the specific subjects hereof and thereof.

Section 8. Governing Law. This Amendment shall be governed by and construed in accordance with the laws of the State of Minnesota.

Section 9. Counterparts. This Amendment may be executed in any number of counterparts, each of which when so executed and delivered shall be deemed to be an original, and all of which counterparts of this Amendment when taken together, shall constitute one and the same instrument.

EXHIBIT A

DEBIT CARD TRANSACTION FEE SCHEDULE

Carrier agrees to pay Bank charges for PIN-based Internet Debit Card Transactions according to the following processing fee schedule.

A. A fee for all PIN-based Internet Debit Card Transactions equal to [***] of all Gross Card Sales during such period. "Gross Card Sales" means the total gross dollar amount of Debit Card sales transactions submitted by Carrier in an applicable period. In addition, Carrier shall be charged a [***] per item fee based upon Gross Card Transactions. "Gross Card Transactions" means the total gross number of transaction items, including sales and refunds submitted by Carrier in an applicable period.

B. Card Authorization costs, data capture costs, and equipment rental or purchase costs (to the extent Carrier requests such equipment) will be paid directly by Carrier.

C. Bank will assess a [***] handling fee for each and every Chargeback received by Bank during any 30 calendar day period in which there is at least a [***] ratio of Chargebacks received by Bank to net sales volume. Carrier acknowledges and agrees that such fees constitute reasonable compensation to Bank for the services provided by Bank in connection with the handling of Chargebacks, taking into account, among other things, the costs and expenses, whether direct or indirect, and whether out-of-pocket or attributable to an increased administrative burden, incurred or suffered by Bank as a result of such Chargeback activity. As an accommodation to Carrier, Bank will charge the handling fee specified herein only when the ratio of Chargebacks to net sales volume equals or exceeds [***] during any applicable period.

D. The rate specified in paragraph A for Gross Card Sales above may be adjusted from time to time to reflect and correspond to: (1) increases or decreases in applicable rates, fees and assessments established and levied by the applicable Card Associations and (2) increases or decreases in Bank's transaction processing costs.

E. Upon the upgrade of Bank's systems, Carrier and Bank shall endeavor to amend this Debit Card Transaction Fee Schedule to convert from the flat rate pricing to a pricing model in which interchange and assessments from the EFT Networks and the Credit Card Associations are passed through at cost and (i) a mark up as Bank's fee equal to [***], plus (ii) Acculynk's fee equal to [***] plus [***] for Acculynk's fee, each assessed on Gross Card Sales.

L. Rights; Delays. All rights and remedies of the parties are cumulative and not alternative and do not exclude any rights under law or in equity. A failure or delay by either party to enforce at any time any of its rights shall not be construed as a waiver thereof.

M. Saving Clause.

• you have not been notified by us of the cancellation or other invalidity of the Card

having Extended Payment with us. You should not ask a Cardmember if he wishes to elect Extended Payment, but if he indicates he does, record the Cardmember's election by an entry on the Charge Record and on the Transmission, if you submit electronically.

D. Future Technology. If in the future you use any ticketing or sales method not described in this Agreement, you agree to notify us in advance of implementation so that we can assess its feasibility for Card acceptance and determine what changes to our terms, conditions and procedures, if any, are needed.

All Authorization requests must meet the Authorization Minimum Data Standards provided by us.

"Authorization" simply means you have contacted us and we consent to your proceeding to the next step of the transaction, subject to your complying with all other terms of this Agreement. It is not a guarantee of payment or that the person making the Charge is the right Cardmember, and it does not cure any failure by you to comply with any part of this Agreement or impair any right to Full Recourse we may have with respect to that Charge.

A. No Cash Refunds. When a Cardmember is due a refund for a Charge, you will issue a credit promptly to his/her Card account as described below ("Credit") and not give any cash refunds.

B. Creating Credit Records. Whether or not you submit Credits electronically, you must create a record of each Credit using a credit record agreed upon by you and us ("Credit Record"), a copy of which you will give or send to the Cardmember at the time of refund. Credits must be prepared in the currency in which the original Charge was submitted to us.

C. Submitting Credits. A Credit must be submitted to us promptly but no later than 7 days after the Credit is issued.

A. Responding to Inquiries. If we contact you regarding a claim, complaint or question about any Charge ("Disputed Charge"), you agree to respond to us in writing or electronically within 25 days of your receipt of our request.

B. Cardmember Rights under Law. If a Cardmember, despite your reply within or after the 25 day period, continue to withhold payment for the Disputed Charge and we believe, in good faith, that the Cardmember has the right under applicable law to withhold such payment, then we will have Full Recourse for the amount in dispute.

C. Disproportionate Disputed Charges. In addition, if we are receiving a disproportionate number of Disputed Charges or Charges without Authorization due to downtime of your systems, we will have the right to Full Recourse with respect to all such Charges irrespective of the time periods specified above, and we may withhold additional amounts from payments due you as reserve to protect against future Disputed Charges.

D. Delayed Disputed Charges. As a courtesy to you, and without prejudice to our rights, if a Disputed Charge arises more than 12 months after the Charge was posted to the Cardmember's account, our normal practice is not to send it to you, unless we believe it may involve any fraud or intentional wrongdoing on your part or unless you agree to accept it. We reserve the right to change this practice with respect to you if it results in unacceptable losses or customer dissatisfaction. For the avoidance of doubt, the above deadline will not apply where efforts to investigate or otherwise find a solution to a Disputed Charge began prior to such 12 month period.

10. CHARGEBACKS

A. Currency. When we exercise the right to Full Recourse (see Section 6 of main part of this Agreement), the amount charged back to you will be calculated in the currency in which the Charge was submitted.

B. Cardmember Collections. If you decide to pursue collection from a Cardmember of any Charge for which we exercised Full Recourse, you agree to do so only if permitted by applicable law and only if the Cardmember has authorized the Charge. If you request, we will provide you such reasonable information or documentation relevant to the Disputed Charge as permitted by our company policies and applicable law.

13

middle appraisal, the low appraisal and/or the high appraisal shall be disregarded.

Spirit Airlines - A320 FAMILY - PA 31

(iv) arising from failure to conform to the Specification, except as to those portions of the Specification that are expressly stated in the Specification to be estimates or approximations or design aims.

For the purposes of this Agreement, the term "Warranted Part" will mean any Seller proprietary component, equipment, accessory or part, which is installed on an Aircraft at Delivery and (a) which is manufactured to the detail design of the Seller or a subcontractor of the Seller and (b) which bears a part number of the Seller at the time of Delivery.

12.1.2 Exceptions

The warranties set forth in Clause 12.1.1 will not apply to Buyer Furnished Equipment, Propulsion Systems, or to any component, accessory, equipment or part purchased by the Buyer that is not a Warranted Part, provided, however, that:

(i) any defect in the Seller's workmanship in respect of the installation of such items in the Aircraft, including any failure by the Seller to conform to the installation instructions of the manufacturers of such items that invalidates any applicable warranty from such manufacturers, will constitute a defect in workmanship for the purpose of this Clause 12.1 and be covered by the warranty set forth in Clause 12.1.1(ii), and

(ii) any defect inherent in the Seller's design of the installation, considering the state of the art at the date of such design, that impairs the use of such items will constitute a defect in design for the purposes of this Clause 12.1 and be covered by the warranty set forth in Clause 12.1.1(iii).

The Buyer will in no event be credited for repair costs (labor and material) for any Warranted Part exceeding [***] of the Seller's current catalog price for a replacement of such defective Warranted Part or (exceeding those costs that would have resulted if repairs had been carried out at the Seller's facilities.

The Seller will substantiate these costs in writing on reasonable request by the Buyer.

(vii) Scrapped Material

The Buyer may, with the agreement of the Seller's Resident Customer Support Representative, scrap any such defective parts that are beyond economic repair and not required for technical evaluation.

If the Buyer does not obtain the agreement of the Seller's Resident Customer Support Representative to scrap a Warranted Part defective beyond economic repair, then the Buyer will retain such Warranted Part and any defective part removed from a Warranted Part during repair for a period of either [***] after the date of completion of repair or [***] after submission of a claim for In-house Warranty credit relating thereto, whichever is longer. Such parts will be returned to the Seller at Seller's cost within [***] of receipt of the Seller's request to that effect.

Scrapped Warranted Parts will be evidenced by a record of scrapped material certified by an authorized representative of the Buyer, which will be kept in the Buyer's file for the longer of (i) the duration of the Warranty Period or (ii) the period required under the applicable regulations of the Aviation Authority.

21.1.3 Actual or liquidated damages shall be payable by Buyer promptly, and in any event within ten (10) days of the date of written notice and demand therefor from Seller, such demand to set forth in reasonable detail the calculation of such actual or liquidated damages and shall identify the Termination Event upon which the Seller is relying. The parties agree that the remedy of liquidated damages is not to be denied to the Seller due to the inability of Seller to deliver a notice and demand for payment thereof due to the operation of law following a bankruptcy or other Termination Event under Sub-clause 21.1(1) - (4). The parties further agree that in circumstances where a Termination Event has occurred and the Seller does not cancel this Agreement as to any or all Aircraft, but instead seeks to recover its actual damages resulting therefrom, the amount of actual damages payable by the Buyer shall not exceed the amount of liquidated damages that could have been claimed by Seller pursuant to Clause 21.2 (2) had the Seller elected to claim, as a result of such Termination Event, liquidated damages pursuant to Clause 21.2(2).

21.1.4 The parties to this Agreement are commercially sophisticated parties represented by competent counsel. The parties expressly agree and declare that damages for material breach of this Agreement by the Buyer resulting in a Termination of this Agreement as to any or all Aircraft have been liquidated at amounts which are reasonable in light of the anticipated or actual harm caused by the Buyer's breach, the difficulties of proof of loss and the nonfeasibility of otherwise obtaining an adequate remedy. It is understood and agreed by the parties that the amount of liquidated damages set forth herein is the total amount of monetary damages, no more and no less, to which the Seller will be entitled for and with respect to any Aircraft as recovery for material breach of this Agreement by Buyer resulting in a Termination by the Seller of this Agreement as to such Aircraft.

21.1.5 The terms "Affected Aircraft", "Applicable Date and "Escalated Price" are defined as follows:

(i) "Affected Aircraft" - (a) any or all Aircraft with respect to which the Seller has cancelled or terminated this Agreement pursuant to Sub-clause 21.1.2(1)(iv).

(ii) "Applicable Date" - for any Affected Aircraft the date of the Termination Event which the Seller specifies in its notice and demand for payment of liquidated damages delivered under Sub-Clause 21.1(3).

(iii) "Escalated Price" -·the sum of (i) the Base Price of the Airframe (set forth in Clause 3.1.1 hereof), (ii) the Base Price of SCNs and MSCNs entered into after the date of this Agreement, and (iii) the reference Price of the Propulsion systems, all as escalated to the Applicable Date in accordance with the provisions of Clause 4 of this Agreement.

21.1.6 Promptly upon obtaining knowledge of the occurrence of a Termination Event by the Buyer, the Buyer will notify the Seller of such occurrence in writing, provided, that

Spirit Airlines - A320 FAMILY - PA 88

any failure by the Buyer to notify the Seller will not prejudice the Seller's rights or remedies hereunder.

21.2 If at any time prior to Scheduled Delivery Date of an Aircraft, the Seller has reasonable grounds for insecurity as to the ability of the Buyer to perform its obligation to take Delivery of such Aircraft, then the Seller will send the Buyer a written demand for adequate assurance of performance. If adequate assurance acceptable to the Seller is not received within thirty days following the date of such written demand, then the Seller will have the right to either (a) exercise the remedies provided under Section 2-609 of the Uniform Commercial Code or (b) exercise any of its remedies under Clause 21.2 of this Agreement.

If the US Department of Labor substantially revises the methodology of calculation or discontinues any of the indexes referred to hereabove, AVSA will reflect the substitute for the revised or discontinued index selected by INTERNATIONAL AERO ENGINES, such substitute index to lead in application to the same adjustment result, insofar as possible, as would have been achieved by continuing the use of the original index as it may have fluctuated had it not been revised or discontinued.

Appropriate revision of the formula will be made to accomplish this result.

5.4 Annulment of Formula

Should the above escalation provisions become null and void by action of the US Government, the price will be adjusted due to increases in the costs of labor and material which have occurred from the period represented by the applicable Reference

Price Indexes to average of the fifth (5th), sixth (6th) and seventh (7th) months prior to the scheduled Aircraft delivery.

12. LEASING OF SPARE PARTS

12.1 Applicable Terms

The terms and conditions of this Paragraph 12 will apply to the Lease of Seller Parts listed in Appendix "A" to this Paragraph 12 ("Leased Parts") and will form a part of each lease of any Leased Part by the Buyer from the Seller after the date hereof. Except for the description of the Leased Part, the Lease Term, the Leased Part delivery and return locations and the Lease Charges (defined below in Paragraph 12.4), all other terms and conditions appearing on any order form or other document pertaining to Leased Parts will be deemed inapplicable, and in lieu thereof the terms and conditions of this Paragraph 12 will prevail. For

Spirit Airlines - A320 Family Aircraft LA1-21

purposes of this Paragraph 12, the term "Lessor" refers to the Seller and the term "Lessee" refers to the Buyer. Parts not included in Appendix "A" to this Paragraph 12 may be supplied under a separate lease agreement between the Seller and the Buyer or as mutually agreed by the parties.

12.2 Lease Procedure: Spare Parts Leased

At the Lessee's request by telephone (to be confirmed promptly in writing), facsimile, letter or other written instrument, the Lessor will lease Leased Parts, which will be made available in accordance with Paragraph 4.2.3 of this Letter Agreement 1, to the Lessee as substitutes for parts removed from an Aircraft for repair or overhaul. Each lease of Leased Parts will be evidenced by a lease document ("Lease") issued by the Lessor to the Lessee no later than seven (7) business days after delivery of the Leased Part.

12.3 Lease Term: Return

The term of the lease ("Lease Term") will commence on the date of receipt of the Leased Part by the Lessee or its agent at the Lessor's facility and will end on the date on which such Leased Part is returned to the Lessor. The Lease Term will not exceed thirty (30) days, unless extended by written agreement between Lessor and Lessee within such thirty (30)-day period (no one such extension to exceed an additional thirty (30) days). Notwithstanding the foregoing, the Lease Term will end in the event, and upon the date, of exercise of the Lessee's option to either purchase or exchange the Leased Part, as provided herein.

12.4 Lease Charges and Taxes

The Lessee will pay the Lessor (a) [***], (b) any reasonable additional costs which may be incurred by the Lessor as a direct result of such Lease, such as inspection, test, repair, and repacking costs as required to place the Leased Part in satisfactory condition for Lease to a subsequent customer, (c) all transportation and insurance charges and (d) any taxes, charges or customs duties imposed upon the Lessor or its property as a result of the lease, sale, delivery, storage or transfer of any Leased Part (the "Lease Charges"). All payments due hereunder will be made in accordance with Paragraph 6 of this Letter Agreement 1.

Spirit Airlines - A320 Family Aircraft LA1-22

In the event that the Leased Part has not been returned to the Lessor's designated facilities within the time period provided in Paragraph 12.3 above, the Lessor will be entitled, in addition to any other remedy it may have at law or under this Paragraph 12, to charge to the Lessee, and the Lessee will pay, the charges referred to in this Paragraph 12.4 accruing for each day after the end of the Lease Term and for as long as such Leased Part is not returned to the Lessor and as though the Lease Term were extended to the period of such delay.

12.5 Title

Title to each Leased Part will remain with the Lessor at all times unless the Lessee exercises its option to purchase it in accordance with Paragraph 12.8 of this Letter Agreement 1, in which case title will pass to the Lessee in accordance with Paragraph 7 of this Letter Agreement 1.

12.6 Risk of Loss

Except for normal wear and tear, each Leased Part will be returned to the Lessor in the same condition as when delivered to the Lessee. The Lessee will not without the Lessor's prior written consent, modify or alter any Leased Part. Risk of loss or damage to each Leased Part will remain with the Lessee until such Leased Part is redelivered to the Lessor at the return location specified in the applicable Lease. If a Leased Part is lost or damaged beyond repair, the Lessee will be deemed to have exercised its option to purchase the part in accordance with Paragraph 12.8 of this Letter Agreement 1, as of the date of such loss or damage.

12.7 Record of Flight Hours

All flight hours accumulated by the Lessee on each Leased Part during the Lease Term will be documented by the Lessee. Records will be delivered to the Lessor upon return of such Leased Part to the Lessor. In addition, all documentation pertinent to inspection, maintenance and/or rework of the Leased Part as maintained serviceable in accordance with the standards of the Lessor will be delivered to the Lessor upon return of the Leased Part to the Lessor on termination of the Lease.

Spirit Airlines - A320 Family Aircraft LA1-23

Such documentation will include but not be limited to evidence of incidents such as hard landings, abnormalities of operation and corrective action taken by the Lessee as a result of such incidents.

12.8 Option to Purchase

12.8.1 Option to Purchase

The Lessee may at its option, exercisable by written notice given to the Lessor, elect during or at the end of the Lease Term to purchase the Leased Part, in which case the then current purchase price for such Leased Part as set forth in the Seller's Spare Parts Price List will be paid by the Lessee to the Lessor. The immediately preceding sentence will apply to new Leased Parts only. In the event the Leased Part is used, [***] of the then current catalog price for the new part with a part number corresponding to such Leased Part will be paid by the Lessee to the Lessor. Such option will be contingent upon the Lessee providing the Lessor with evidence satisfactory to the Lessor that the original part fitted to the Aircraft is beyond economical repair. Should the Lessee exercise such option, [***] of the Lease rental charges already invoiced pursuant to Paragraph 12.4(a) will be credited to the Lessee against the said purchase price of the Leased Part.

In the event that the removed part is beyond economic repair and the Leased Part is a used part, the Buyer may elect to order a new part from the Seller and continue to lease the Leased Part under the conditions of Paragraph 12.4 until such time as the new part is delivered. The purchase price of the new part will be discounted by [***] of the lease charges paid in respect of the Leased Part. Should the Lessee fail to return the Leased Part to the Lessor at the end of the Lease Term, such failure will be deemed to be an election by the Lessee to purchase the Leased Part.

12.8.2 In the event of purchase, the Leased Part will be warranted in accordance with Paragraph 11 of this Letter Agreement 1 as though such Leased Part were a Seller Part; provided, however, that (i) the Seller will prorate the full Warranty Period granted to the Buyer according to the actual usage of such Leased Part and (ii) in no event will such Warranty period be less than [***] from the date of purchase of such Leased Part. A warranty granted under this Paragraph 12.8.2 will be in substitution for the warranty granted under Paragraph 12.9 at the commencement of the Lease Term.

12.9.5 Limitation of Warranty

7 - CERTIFICATION

Except as set forth in this Clause 7, the Seller will not be required to obtain any certificate or approval with respect to the Aircraft.

7.1 Type Certification

The Aircraft have been type certificated under EASA procedures for joint certification in the transport category. The Seller will obtain or cause to be obtained an FAA type certificate (the "Type Certificate") to allow the issuance of the Export Certificate of Airworthiness.

7.2 Export Certificate of Airworthiness

Subject to the provisions of Clause 7.3, each Aircraft will be delivered to the Buyer with an Export Certificate of Airworthiness issued by the DGAC, or the LBA, as applicable, and in a condition enabling the Buyer (or an eligible person under then applicable law) to obtain immediately and without repair, maintenance or modification at the time of Delivery a Standard Airworthiness Certificate issued pursuant to Part 21 of the US Federal Aviation Regulations. [***] However, the Seller will have no obligation, whether before, at or after Delivery of any Aircraft, to make any alterations (including all related costs) to such Aircraft to enable such Aircraft to meet FAA or U.S. Department of Transportation requirements for specific operation on the Buyer's routes, except as may be provided for in this Agreement.

If the FAA requires a modification to comply with additional aircraft import requirements and/or supply of additional data before the issuance of the Export Certificate of Airworthiness, the parties hereto will sign an SCN for such modification which, the Seller will incorporate as specified in such modification and/or the Seller will provide such data, in either case, at costs to be borne by the Buyer.

7.3 Specification Changes Before Delivery

7.3.1 If, any time before the date on which the Aircraft is Ready for Delivery, any law, rule or regulation is enacted, promulgated, becomes effective and/or an interpretation of any law, rule or regulation is issued by the EASA that requires any change to the Specification for the purposes of obtaining the Export Certificate of Airworthiness (a "Change in Law"), the Seller will make the required modification and the parties hereto will sign an SCN.

Spirit Airlines - A320 Family Aircraft LA11-3

7.3.2 The Seller will as far as practicable, but at its sole discretion, take into account the information available to it concerning any proposed law, rule or regulation or interpretation that could become a Change in Law, in order to minimize the costs of changes to the Specification as a result of such proposed law, regulation or interpretation becoming effective.

7.3.3 [***]

7.3.4 Notwithstanding the provisions of Clauses 7.3.3, if a Change in Law relates to an item of BFE or to the Propulsion Systems (and, in particular, to engine accessories, quick engine change units or thrust reversers) the costs will be borne in accordance with such arrangements as may be made separately between the Buyer and the manufacturer of the BFE or the Propulsion Systems, as applicable, and the Seller will have no obligation with respect thereto.

7.3.5 [***]

Spirit Airlines - A320 Family Aircraft LA11-4

7.4 Specification Changes After Delivery

Nothing in Clause 7.3 will require the Seller to make any changes or modifications to, or to make any payments or take any other action with respect to, any Aircraft that is Ready for Delivery before the compliance date of any law or regulation referred to in Clause 7.3. Any such changes or modifications made to an Aircraft after it is Ready for Delivery will be at the Buyer's expense.

APPENDIX 1

18 Buyer Furnished Equipment

18.1 Administration

18.1.1.1 In accordance with the Specification, the Seller shall install those items of equipment that are identified in the Specification as being furnished by the Buyer ("Buyer Furnished Equipment" or "BFE"), provided that the BFE and the supplier of such BFE (the "BFE Supplier") are referred to in the Airbus BFE Product Catalog valid at the time the BFE Supplier is selected.

18.1.1.2 Notwithstanding the foregoing and without prejudice to Clause 2.4, if the Buyer wishes to install BFE manufactured by a supplier who is not referred to in the Airbus BFE Product Catalog, the Buyer shall so inform the Seller and the Seller shall conduct a feasibility study of the Buyer's request, in order to consider approving such supplier, provided that such request is compatible with the Seller's industrial planning and the associated Scheduled Delivery Month for the Buyer's Aircraft. In addition, it is a prerequisite to such approval that the considered supplier be qualified by the Seller's Aviation Authorities to produce equipment for installation on civil aircraft. Any approval of a supplier by the Seller shall be performed at the Buyer's expense. The Buyer shall cause any BFE supplier approved under this Clause 18.1.1.2 (each an "Approved BFE Supplier") to comply with the conditions set forth in this Clause 18 and specifically Clause 18.2.

Except for the specific purposes of this Clause 18.1.1.2, the term "BFE Supplier" shall be deemed to include Approved BFE Suppliers.

18.1.2.1 The Seller shall advise the Buyer of the dates by which, in the planned release of engineering for the Aircraft, the Seller requires a written detailed engineering definition, encompassing a Declaration of Design and Performance (the "BFE Engineering Definition"). The Seller shall provide to the Buyer and/or the BFE Supplier(s), within an appropriate timeframe, the necessary interface documentation to enable the development of the BFE Engineering Definition.

The BFE Engineering Definition shall include the description of the dimensions and weight of BFE, the information related to its certification and the information necessary for the installation and operation thereof, including when applicable 3D models compatible with the Seller's systems. The Buyer shall furnish, or cause the BFE Suppliers to furnish, the BFE Engineering Definition by the dates specified.

Thereafter, the BFE Engineering Definition shall not be revised, except through an SCN executed in accordance with Clause 2.

APPENDIX 1

18.1.2.2 The Seller shall also provide in due time to the Buyer a schedule of dates and the shipping addresses for delivery of the BFE and, where requested by the Seller, additional spare BFE to permit installation in the Aircraft and Delivery of the Aircraft in accordance with the Aircraft delivery schedule. The Buyer shall provide, or cause the BFE Suppliers to provide, the BFE by such dates in a serviceable condition, in order to allow performance of any assembly, installation, test or acceptance process in accordance with the Seller's industrial schedule. In order to facilitate the follow-up of the timely receipt of BFE, the Buyer shall, upon the Seller's request, provide to the Seller dates and references of all BFE purchase orders placed by the Buyer.

The Buyer shall also provide, when requested by the Seller, at Airbus Operations S.A.S. works in Toulouse, France, at Airbus Operations GmbH Works in Hamburg, Germany and/or the Airbus Americas Inc. facility in Mobile, Alabama, as applicable, adequate field service including support from BFE suppliers to act in a technical advisory capacity to the Seller in the installation, calibration and possible repair of any BFE.

18.1.3 Without prejudice to the Buyer's obligations hereunder, in order to facilitate the development of the BFE Engineering Definition, the Seller shall organize meetings between the Buyer and BFE Suppliers. The Buyer hereby agrees to participate in such meetings and to provide adequate technical and engineering expertise to reach decisions within the defined timeframe.

In addition, throughout the development phase and up to Delivery of the Aircraft to the Buyer, the Buyer agrees:

• to monitor the BFE Suppliers and ensure that they shall enable the Buyer to fulfil its obligations, including but not limited to those set forth in the Customization Milestone Chart;

• that, should a timeframe, quality or other type of risk be identified at a given BFE Supplier, the Buyer shall allocate resources to such BFE Supplier so as not to jeopardize the industrial schedule of the Aircraft;

• for major BFE, including, but not being limited to, seats, galleys and IFE ("Major BFE") to participate on a mandatory basis in the specific meetings that take place between BFE Supplier selection and BFE delivery, namely:

◦ Preliminary Design Review ("PDR"),

◦ Critical Design Review ("CDR");

• to attend the First Article Inspection ("FAI") for the first shipset of all Major BFE. Should the Buyer not attend such FAI, the Buyer shall delegate the FAI

APPENDIX 1

to the BFE Supplier and confirmation thereof shall be supplied to the Seller in writing;

• to attend the Source Inspection ("SI") that takes place at the BFE Supplier's premises prior to shipping, for each shipset of all Major BFE. Should the Buyer not attend such SI, the Buyer shall delegate the SI to the BFE Supplier and confirmation thereof shall be brought to the Seller in writing. Should the Buyer not attend the SI, the Buyer shall be deemed to have accepted the conclusions of the BFE Supplier with respect to such SI.

The Seller shall be entitled to attend the PDR, the CDR and the FAI. In doing so, the Seller's employees shall be acting in an advisory capacity only and at no time shall they be deemed to be acting as Buyer's employees or agents, either directly or indirectly.

18.1.4.1 The BFE shall be imported into FRANCE or into GERMANY by the Buyer under a suspensive customs system ("Régime de l'entrepôt douanier ou régime de perfectionnement actif " or "Zollverschluss") without application of any French or German tax or customs duty, and shall be Delivered At Place (DAP) according to the Incoterms, to the following shipping addresses:

AIRBUS OPERATIONS S.A.S.

316 Route de Bayonne

31300 TOULOUSE

GERMANY

or such other location as may be specified by the Seller.

18.1.4.2 BFE delivered to the Seller's Affiliate in Mobile, Alabama, as may be specified by the Seller pursuant to Clause 18.1.4.1, will be shipped according to the Incoterms 2010 "Delivered Duty Paid" Airbus Americas, Inc., Mobile, Alabama.

18.1.5 If the Buyer requests the Seller to supply directly certain items that are considered BFE according to the Specification, and if such request is notified to the Seller in due time in order not to affect the delivery date of the Aircraft, the Seller will agree to order such items subject to the execution of an SCN reflecting the effect on price, escalation adjustment, and any other conditions of the Agreement including a handling charge in the amount of [***] of the cost of the BFE item for any items up

APPENDIX 1

to [***]. If the cost of the BFE item exceeds [***] the Buyer and the Seller will execute an SCN reflecting the cost of such BFE and a handling charge to be mutually agreed upon execution of such SCN. The Seller will bear no liability in respect of delay and product support commitments for such items.

18.2 Requirements

The Buyer is responsible for ensuring, at its expense, and warrants that the BFE shall:

• be manufactured by a qualified BFE Supplier, and

• meet the requirements of the applicable Specification of the Aircraft, and

• be delivered with the relevant certification documentation, including but not limited to the DDP, and

• comply with the BFE Engineering Definition, and

• comply with applicable requirements incorporated by reference to the Type Certificate and listed in the Type Certificate Data Sheet, and

• be approved by the Aviation Authority issuing the Export Airworthiness Certificate and by the Buyer's Aviation Authority for installation and use on the Aircraft at the time of Delivery of the Aircraft, and

• not infringe any patent, copyright or other intellectual property right of the Seller or any third party, and

• not be subject to any legal obligation or other encumbrance that may prevent, hinder or delay the installation of the BFE in the Aircraft and/or the Delivery of the Aircraft.

The Seller shall be entitled to refuse any item of BFE that it considers incompatible with the Specification, the BFE Engineering Definition or the certification requirements.

18.3 Buyer's Obligation and Seller's Remedies

18.3.1 Any delay or failure in

(i) furnishing the BFE in serviceable condition at the requested delivery date,

(ii) complying with Clause 18.2 or in providing the descriptive information or service representatives required by Clause 18.1.1, or

APPENDIX 1

(iii) obtaining any required approval for such equipment under the Aviation Authorities' regulations

may delay the performance of any act to be performed by the Seller, and cause the Final Contract Price of the Aircraft to be adjusted in accordance with the updated delivery schedule and the provisions of Clause 10. The additional costs the Seller incurs that are attributable in any material degree to such delay for storage, taxes, insurance and out of sequence installation shall be for the Buyer's account. The Seller shall use its reasonable efforts to minimize or mitigate such delay.

18.3.2 The Buyer will use reasonable commercial efforts to monitor the manufacturing, inspection and timely availability of BFE to meet the Seller's delivery requirements.

(i) if the Buyer discovers that the BFE delivery program is behind schedule and determines in conjunction with the BFE manufacturer that the Seller's delivery requirements cannot be met, the Buyer will, without delay, notify the Seller of the situation and of the expected delivery dates. The Buyer and Seller will mutually agree on a plan to minimize any additional costs for changes to the Seller's production program to accommodate the delay in BFE delivery. Any such additional costs will be borne by the Buyer.

(ii) provided such delay is in excess of [***] and a mutual agreement with respect to a recovery plan referred to in (i) above has not been reached, in addition to the consequences outlined in Clause 18.3.1, in the event of a delay or failure described in 18.3.1, the Seller, using reasonable efforts to mitigate cost, may select, purchase and install equipment similar to the BFE at issue, in which event the Final Contract Price of the affected Aircraft will also be increased by the actual purchase price of such equipment, plus handling charge in the amount of [***] of the purchase price of the BFE item and the cost of transportation, insurance, packaging and, if required and not already provided for in the price of the Aircraft, for inspection, acceptance, adjustment and calibration; or

(iii) if the BFE is delayed more than [***] beyond, or unapproved within, [***] of the date referenced in Clause 18.1.1, then the Seller may deliver or the Buyer may elect to have the Aircraft delivered without the installation of such BFE, notwithstanding the terms of Clause 7.2 insofar as it may otherwise have applied, whereon the Seller will be relieved of all obligations to install such equipment.

18.4 Title and Risk of Loss

Title to and risk of loss of BFE will at all times remain with the Buyer, except that risk of loss (limited to cost of replacement of said BFE and excluding in particular

APPENDIX 1

loss of use) will be with the Seller for as long as the BFE is in the care, custody and control of the Seller.

18.5 Disposition of BFE Following Termination

18.5.1 If a termination of this Agreement pursuant to the provisions of Clause 21 hereof occurs with respect to an Aircraft in which all or any part of the BFE has been installed prior to the date of such termination, the Seller will be entitled, but not required, to remove all items of BFE which can be removed without damage to the Aircraft and to undertake commercially reasonable efforts to facilitate the sale of such items of BFE to other customers, retaining and applying the proceeds of such sales to reduce Seller's damages resulting from the termination.

18.5.2 The Buyer will cooperate with the Seller in facilitating the sale of BFE pursuant to Clause 18.5.1 above and will be responsible for all reasonable costs incurred by the Seller in removing and facilitating the sale of such BFE. The Buyer will reimburse the Seller for all such reasonable costs within [***] of receiving documentation substantiating such costs from the Seller.

18.5.3 The Seller will notify the Buyer as to those items of BFE not sold by the Seller pursuant to Clause 18.5.1 above and, at the Seller's request, the Buyer will undertake to remove such items from the Seller' facility within [***] of the date of such notice. The Buyer will have no claim against the Seller for damage or destruction of any item of BFE removed from the Aircraft and not removed from Seller's facility within such period.

18.5.4 The Buyer will have no claim against the Seller for damage to or destruction of any item of BFE damaged or destroyed in the process of being deinstalled from the Aircraft, provided that the Seller shall have used reasonable care in such deinstallation.

18.5.5 The Buyer at no cost to the Seller will grant title to the Seller for any BFE items that cannot be removed from the Aircraft without causing damage to the Aircraft or rendering any system in the Aircraft unusable.

18.5.6 If the termination was not a result of an Excusable Delay attributable to the Buyer or a Buyer Termination Event, the Seller shall pay the Buyer for the cost of such BFE.

Member, Servicer or any Secured Party will hold the Deposit as security for the due and punctual payment of and performance by Carrier of the Obligations.

(U.S. Transactions)

6

(b) To the extent Carrier has or may at any time acquire any rights in Carrier's Rights, Carrier grants to each of Servicer, Member, and all other Secured Parties a Lien on the Deposit and all other Carrier's Rights to secure the payment and performance by Carrier of all Obligations. Each Secured Party shall act as agent for all Secured Parties to the extent that any such Secured Party controls or possesses the Deposit or any collateral hereunder or is named as Secured Party on any filing, registration or recording. Carrier hereby acknowledges that notwithstanding the foregoing grant of a Lien, Reserved Funds represent only a future right to payment owed to Carrier under the Agreement, payment of which is subject to the terms and conditions of the Agreement and to Carrier's complete and irrevocable fulfillment of its obligations and duties under the Agreement and do not constitute funds of Carrier.

(c) Carrier further agrees that during the term of the Agreement, Carrier shall not grant, or attempt to grant, to any other Person or suffer to exist in favor of any other Person any Lien or other interest in Carrier's Rights (if any) unless any such Lien or other interest and the priority thereof are subject to a subordination agreement in favor of Member, Servicer and all other Secured Parties and reasonably satisfactory to Servicer.

(d) Carrier hereby acknowledges that Member and Servicer dispute the existence of any interest of Carrier in any rights to payment from Cardholders or Card Issuers arising out of the Sales Records and further acknowledges that to the extent it may have an interest therein, such interest is subordinate to the interests of the Secured Parties and of any of their respective subrogees.

(e) Carrier will do all acts and things, and will execute, endorse, deliver, file, register or record all instruments, statements, declarations or agreements (including pledges, assignments, security agreements, financing statements, continuation statements, etc.) reasonably requested by Servicer, in form reasonably satisfactory to Servicer, to establish, perfect, maintain and continue the perfection and priority of the security interest and hypothec of Secured Parties in all Carrier's Rights and in all proceeds of the foregoing, as granted by Carrier pursuant to Section 2(b) and 2(d) of this Exposure Protection Schedule.

Without limiting the foregoing, Carrier hereby authorizes Servicer to file one or more financing statements or continuation statements in respect hereof, and amendments thereto, relating to any part of the collateral described herein without the signature of Carrier. A carbon, photographic or other reproduction of the Agreement or of a financing statement shall be sufficient as a financing statement and may be filed in lieu of the original in any or all jurisdictions which accept such reproductions.

3. Adjustments to Deposit

(a) Servicer will use the Methodology described in Section 8 of this Exposure Protection Schedule (the "Methodology") to calculate Gross Exposure each Business Day. Carrier acknowledges that Servicer has explained to it and it understands Servicer's Methodology for determining Gross Exposure and the amount of the Aggregate Protection and hereby agrees to be bound by such Methodology and the determinations made by Servicer as a result thereof, absent manifest error. Among other things, Carrier understands that Gross Exposure includes the value of Travel Costs for goods or services sold to Cardholders who used their Cards to purchase such goods or services with respect to which Carrier has not yet provided such goods or services. Servicer and Carrier may change the Methodology by mutual agreement.

(U.S. Transactions)

7

(b) The amount of the Deposit shall be increased or decreased each Business Day, as appropriate, based on the Methodology so that the amount of the Aggregate Protection will at all times equal the Required Amount. Any necessary increases to the Deposit may be made, at Servicer's sole discretion by Member or Servicer withholding as Reserved Funds an amount up to [***] of amounts otherwise payable to Carrier under Section 6.2 of the MTOS until the amount of the Aggregate Protection is at least equal to the Required Amount, or by federal wire transfer of immediately available funds from Carrier to an account designated by Servicer, on the second (2nd) Business Day after Carrier's receipt of notice from Servicer that an increase is required and the amount thereof. If the Servicer agrees to permit increases to the amount of the Deposit by wire transfer and the funds required to increase the amount of the Deposit so that the Aggregate Protection is equal to the Required Amount are not transferred to Servicer as required by this Section 3, Member or Servicer may immediately withhold on a daily basis as Reserved Funds an amount up to [***] of amounts otherwise payable to Carrier under Section 6.2 of the MTOS until the amount of the Aggregate Protection at least equals the Required Amount. Member or Servicer shall remit to Carrier from the Deposit the amount necessary to reduce the amount of the Aggregate Protection to equal the Required Amount on each Business Day in accordance with Section 6.2 of the MTOS.

(c) The amount of the Deposit to be maintained hereunder may be reduced in accordance with Section 9 of this Exposure Protection Schedule pursuant to which Servicer accepts Letter of Credit in lieu of all or a portion of the Deposit so long as the Aggregate Protection equals the Required Amount.

(d) Although Servicer has the right at all times to require that the amount of the Aggregate Protection equal the Required Amount, Servicer may, from time to time, in its sole discretion make remittances to Carrier or release portions of any Letter of Credit such that the Aggregate Protection is less than the Required Amount. The duration of any such reduction is within the sole discretion of Servicer. At any time that the amount of the Aggregate Protection is less than the Required Amount Servicer, in its sole discretion, may again require that the amount of the Aggregate Protection equal the Required Amount. Any required increase may be made as provided in Section 3(b) of this Exposure Protection Schedule as determined by Servicer. Any reductions in the amount of the Aggregate Protection as described in this paragraph shall not be deemed a course of dealing nor give rise to any rights by Carrier in the future to require that the amount of the Aggregate Amount be less than the Required Amount.

4. Control of Deposit

Carrier acknowledges that (i) funds remitted to Member or Servicer by Carrier and (ii) funds paid by Card Associations and held by Member, Servicer or any Secured Party as the Deposit may be commingled with other funds of Member, Servicer or such Secured Party, and further acknowledges that all such funds, and any investment of funds shall be in the name and control of Member, Servicer or such Secured Party, and Carrier shall have no interest in any securities, instruments or other contracts or any interest, dividends or other earnings accruing thereon or in connection therewith. It is the understanding of the Parties that, notwithstanding any other provision of the Agreement to the contrary, (a) the sole obligation of Member or Servicer with respect to the Deposit shall be the obligation to pay to Carrier amounts equal to the amounts attributable to Travel Costs with respect to which Carrier has provided goods or services net of any Obligations owed Carrier to any Secured Party, (b) such obligation to make payment to Carrier is at all times subject to the terms of the Agreement, and (c) such payment shall only be due and payable upon complete and irrevocable fulfillment by Carrier of all of its obligations and duties under the Agreement.

5. Investment

To the extent permitted by applicable law or regulation, all amounts held as the Deposit will be deemed to earn a yield equal to the Applicable Rate. The amount so earned shall be credited to the Deposit.

6. Right of Offset; Recoupment; Application

At any time that an amount is due Member, Servicer or any other Secured Party from Carrier, and Member, Servicer or such other Secured Party does not obtain payment of such amount due as provided in the Agreement, Member or Servicer (each on behalf of itself and any other Secured Party) shall have the right to apply, recoup or set off any amounts otherwise owed by Member, Servicer or any other Secured Party to Carrier hereunder, including, without limitation, any amounts attributable to the Deposit, to the amount owed by Carrier. Servicer may exercise any such right for its benefit or the benefit of Member or any other Secured Party. Where any application, recoupment or set off requires the conversion of one currency into another, Servicer or Member shall be entitled to effect such conversion in accordance with its prevailing practice and Carrier shall bear all exchange risks, losses, commissions and other bank charges which may thereafter arise.

7. Retention of Deposit After Cessation of Flight Operations

Notwithstanding any other provision of the Agreement to the contrary, during the period not to exceed [***] months from the earlier of termination of this Agreement or the date upon which Carrier permanently ceases flight operations, Member and Servicer may retain the Deposit and Letters of Credit so that the Aggregate Protection at least equals the Required Amount on each day. As the Required Amount is reduced because Gross Exposure has been reduced in a means acceptable to Servicer, Servicer is obligated to remit sufficient funds from the Deposit and/or return the Letter of Credit to Carrier within two (2) business days of such determination so that the Aggregate Protection does not exceed the Required Amount (except with respect to the Projected Exposure set forth in Section 11). Subject to the foregoing and the eighteen month time frame, Servicer shall continue to hold the Deposit and/or Letters of Credit until Servicer has determined that Carrier has no further Obligations or potential Obligations and Servicer shall be without any obligation to remit funds to Carrier until such time.

8. Methodology

[***]

9. Standby Letter of Credit

(a) The amount of the Aggregate Protection which Servicer or Member may maintain pursuant to this Exposure Protection Schedule shall include the sum of (a) the amount remaining to be drawn upon any valid and outstanding Letter of Credit and (b) the proceeds of any previous draw on a Letter of Credit held by Servicer or Member and not applied. At such time as the Servicer or Member may no longer draw on the Letters of Credit, Servicer may require that the amount of the Deposit plus proceeds of any draw on the Letters of Credit held by Servicer or Member and not applied equal the Required Amount.

(b) Upon the occurrence of any event that gives rise to Servicer's right under this Agreement to make demand on Carrier for payment to Servicer or Member of any Obligations and after (i) application of all amounts held as part of the Deposit and (ii) application of all amounts that would otherwise be payable to Carrier from Member or Servicer under the Agreement on such date, if any, then the Servicer, at its option, may draw on any Letter of Credit issued for its benefit with respect to the Agreement to pay such Obligations in an amount that does not exceed the sum of (A) the amount the Servicer has a right to demand that the Carrier pay the Servicer or Member under this Agreement on such date plus (B) the amounts the Servicer reasonably believes it will have a right to demand that the Carrier pay the Servicer or Member as Obligations during the following seven day period.

(c) Notwithstanding anything to the contrary contained in this Section 9 to the contrary, Servicer may draw upon the full amount of a Letter of Credit if sixty (60) days have passed since Servicer delivered written notice to Carrier that the rating of the bank that issued the Letter of Credit has fallen below (A) [***] under the Moody's Investors Service rating system or (B) [***] under the Standard and Poor's rating system, or (C) if ratings from either of those services are unavailable, the equivalent rating of any of the foregoing under any similar rating system.

(U.S. Transactions)

9

(d) Notwithstanding anything to the contrary contained in this Section 9 to the contrary, Servicer may draw upon the full amount of a Letter of Credit if (i) five (5) Business Days have passed since the rating of the bank that issued the Letter of Credit has fallen below (A) [***] under the Moody's Investors Service rating system or (B) [***] under the Standard and Poor's rating system, or (C) if ratings from either of those services are unavailable, the equivalent rating of any of the foregoing under any similar rating system, (ii) an Insolvency Proceeding is commenced by or against Carrier or (iii) the Letter of Credit is set to expire within 60 days and Servicer has not received notice of renewal of the Letter of Credit or an replacement letter of credit acceptable as to form and issuer in the sole discretion of Servicer.

(e) Carrier acknowledges that subject to its right to receive payments under this Agreement, it has no interest in any proceeds of any draw on any Letter of Credit issued for the benefit of Servicer or Member and that upon any valid draw on any Letter of Credit, Servicer or Member shall be entitled to hold the proceeds thereof for payment of the Obligations under the Agreement and apply such proceeds in payment thereof as and when Servicer reasonably deems appropriate, subject to the provisions of Section 7 of this Exposure Protection Schedule. Neither Servicer nor Member shall have any obligation to remit to any Person any excess proceeds of any draw on any Letter of Credit until expiration of the period specified in Section 7 of this Exposure Protection Schedule. In the event of any dispute between Carrier and the issuer of a Letter of Credit or any subrogee thereof, or any other Person with respect to entitlement to any proceeds of a Letter of Credit, Servicer or Member may retain all such proceeds until final resolution of such dispute by a court of competent jurisdiction, subject to the right of Servicer or Member to retain and apply proceeds in payment of the Obligations. In the event that Servicer or Member draws on a Letter of Credit and holds the proceeds thereof at a time when Carrier is conducting normal flight operations, Servicer or Member, at its option, may include such proceeds in its calculation of coverage for the Required Amount and remittances to Carrier may be made in accordance with Section 2 of this Exposure Protection Schedule as if the proceeds were part of the Deposit. Carrier further agrees that at Servicer's option, any excess proceeds of a Letter of Credit, as determined by Servicer in good faith after taking into account all obligations of the Carrier to the Secured Parties, may be remitted to the issuer of a Letter of Credit, or if the issuer has been reimbursed in full for all amounts owed to it on account of the draw on the Letter of Credit, to the account party thereof.

10. Fare Club Exposure

(a) Notwithstanding anything to the contrary contained in the Letters dated on or about February 10, 2010 or June 13, 2011, the "Fare Club Exposure," as determined in accordance with this Section 10 shall be added to the calculation of Gross Exposure at all times; provided, however, the amount of the Fare Club Exposure will only be modified as of the last Business Day of each month.

(b) Within 10 days of the end of each month, Carrier shall provide Servicer with a report of its Fare Club membership sales for the preceding month made through the use of a Card (the "Fare Club Sales Report").

(c) At the conclusion of each six month period, Servicer shall complete a reconciliation between the actual Fare Club Exposure then held and the actual exposure based upon the Fare Club Sales Reports (the "Reconciled Exposure"). The actual exposure for determining the Reconciled Exposure shall be determined by taking the fare club sales for any particular month and reducing such amount by [***] of the original monthly sale amount in each month after such sale until the amount reaches zero, with the first [***] reduction occurring in the month the fare club sale occurs (the "Exposure Reduction Methodology"). Based upon such reconciliation, the amount of Fare Club Exposure will modified to be equal to the Reconciled Exposure.

(U.S. Transactions)

10

(d) During each successive six month period, the Fare Club Exposure will be determined by (i) using the most recent Reconciled Exposure and reducing such amount in each successive month in accordance with the Exposure Reduction Methodology and (ii) adding to the Fare Club Exposure each month an amount equal to the average monthly amount of fare club sales as determined by the most recent six Fare Club Sales Reports, but subtracting from the Fare Club Exposure an amount determined by applying the Exposure Reduction Methodology in succeeding months to the amounts added to the Fare Club Exposure.

(e) Servicer reserves the right to modify the Fare Club Exposure to the extent that Carrier sells fare club memberships with a term longer than one year. Carrier may request that Servicer adjust the calculation of Fare Club Exposure if at any time more the 40% of the fare club memberships then outstanding, when originally sold, were for terms materially shorter than one year.

11. Deposit Upon Termination of the Agreement.

In the event that any Party gives notice to the other Party of termination of the Agreement or non-renewal, or in the absence of a notice, the Agreement is terminated or a Party attempts to terminate the Agreement, and at such time the Aggregate Protection maintained is less than 100% of Gross Exposure, Servicer may make a reasonable determination based upon historical information with respect to Carrier of Chargebacks and other obligations of Carrier under the Agreement that may arise or be asserted from and after such date ("Projected Exposure"). If the amount of Projected Exposure plus the then applicable Required Amount exceeds the amount of the Aggregate Protection then held or posted, Servicer may, in its sole discretion, demand that Carrier, and Carrier shall upon such demand, immediately remit to Servicer in immediately available funds for Servicer to hold as part of the Aggregate Protection an amount sufficient to cause the amount of the Aggregate Protection to equal Projected Exposure plus the then applicable Required Amount. Upon failure by Carrier to remit such funds by the close of business on the first Business Day after any such demand is made, Servicer in its sole discretion may withhold as Reserved Funds an amount up to [***] of amounts otherwise payable to Carrier under Section 6.2 of the MTOS until the amount of the Aggregate Protection is at least equal to Projected Exposure plus the then applicable Required Amount. Servicer may retain the Aggregate Protection pursuant to the provisions of Section 7 of this Exposure Protection Schedule, except that during such period (i) the amount of the Aggregate Protection shall equal Projected Exposure plus the then applicable Required Amount and (ii) payments shall be remitted to Carrier on each Business Day in the amount by which the amount of the Aggregate Protection exceeds the sum of the Projected Exposure and the then applicable Required Amount. Upon and after the occurrence of an event that would cause the Required Amount to increase, even if the same shall occur after termination or non-renewal, the amount of the Aggregate Protection shall not be less than the new Required Amount plus the Projected Exposure. The provisions of Section 3 of this Exposure Protection Schedule with respect to increases to the Aggregate Protection shall apply in any such circumstance.

12. Compliance Certificate and Monthly Unrestricted Cash Report

Carrier shall furnish Servicer, as soon as practicable, and in any event no later than [***] days after the end of each fiscal quarter, (i) a compliance certificate in the form attached hereto as Attachment 1, and (ii) the quarterly unaudited consolidating financial statements of Carrier. Carrier shall also, promptly upon Servicer's reasonable request for the same, provide any additional financial information requested by Servicer. The compliance certificate shall be signed by the chief financial officer, controller, or an authorized officer of Carrier reasonably acceptable to Servicer.

As soon as available, and in any event within [***] days after the end of each fiscal month, Carrier shall provide Servicer with (i) its unaudited financial statements and (ii) a report, which may be in the form of an electronic mail transmission, of the Cash to Cash Expense Percentage. Upon delivery of each such report, Carrier shall be deemed to have certified to Servicer that all information in such report is true and correct in all material respects as of the date of such report.

Exhibit 97.3

SPIRIT AIRLINES, INC.

Dodd-Frank Clawback Policy

The Board of Directors (the “Board”) of Spirit Airlines, Inc., a Delaware corporation (the “Company”) believes that it is in the best interests of the Company and its shareholders to adopt this Dodd-Frank Clawback Policy (the “Policy”), which provides for the recovery of certain incentive compensation in the event of an Accounting Restatement (as defined below). This Policy is designed to comply with, and shall be interpreted consistent with, Section 10D of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), Rule 10D-1 promulgated under the Exchange Act (“Rule 10D-1”) and Section 303A.14 of the New York Stock Exchange Listed Company Manual (the “Listing Standards”).

1.Administration

Except as specifically set forth herein, this Policy shall be administered by the Board or, if so designated by the Board, the Compensation Committee (the Board or the Compensation Committee, the “Administrator”). The Administrator is authorized to interpret and construe this Policy and to make all determinations necessary, appropriate, or advisable for the administration of this Policy. Any determinations made by the Administrator shall be final and binding on all affected individuals and need not be uniform with respect to each individual covered by the Policy. In the administration of this Policy, the Administrator is authorized and directed to consult with the full Board or such other committees of the Board as may be necessary or appropriate as to matters within the scope of such other committee’s responsibility and authority. Subject to any limitation at applicable law, the Administrator may authorize and empower any officer or employee of the Company to take any and all actions necessary or appropriate to carry out the purpose and intent of this Policy (other than with respect to any recovery under this Policy involving such officer or employee).

2.Definitions

As used in this Policy, the following definitions shall apply:

•“Accounting Restatement” means an accounting restatement of the Company’s financial statements due to the Company’s material noncompliance with any financial reporting requirement under the securities laws, including any required accounting restatement to correct an error in previously issued financial statements that is material to the previously issued financial statements, or that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period.

•“Administrator” has the meaning set forth in Section 1 hereof.

•“Applicable Period” means the three completed fiscal years immediately preceding the date on which the Company is required to prepare an Accounting Restatement, as well as any transition period (that results from a change in the Company’s fiscal year) within or immediately following those three completed fiscal years (except that a transition period that comprises a

period of at least nine months shall count as a completed fiscal year). The “date on which the Company is required to prepare an Accounting Restatement” is the earlier to occur of (a) the date the Board concludes, or reasonably should have concluded, that the Company is required to prepare an Accounting Restatement, or (b) the date a court, regulator, or other legally authorized body directs the Company to prepare an Accounting Restatement, in each case regardless of if or when the restated financial statements are filed.

•“Covered Executives” means the Company’s current and former executive officers, as determined by the Administrator in accordance with the definition of “executive officer” set forth in Rule 10D-1 and the Listing Standards.

•“Erroneously Awarded Compensation” has the meaning set forth in Section 5 of this Policy.

•A “Financial Reporting Measure” is any measure that is determined and presented in accordance with the accounting principles used in preparing the Company’s financial statements, and any measure that is derived wholly or in part from such measure. Financial Reporting Measures include but are not limited to the following (and any measures derived from the following): Company stock price; total shareholder return (“TSR”); revenues; net income; operating income; profitability of one or more reportable segments; financial ratios (e.g., accounts receivable turnover and inventory turnover rates); earnings before interest, taxes, depreciation and amortization (“EBITDA”); funds from operations and adjusted funds from operations; liquidity measures (e.g., working capital, operating cash flow); return measures (e.g., return on invested capital, return on assets); earnings measures (e.g., earnings per share); sales per square foot or same store sales, where sales is subject to an Accounting Restatement; revenue per user, or average revenue per user, where revenue is subject to an Accounting Restatement; cost per employee, where cost is subject to an Accounting Restatement; any of such financial reporting measures relative to a peer group, where the Company’s financial reporting measure is subject to an Accounting Restatement; and tax basis income. A Financial Reporting Measure need not be presented within the Company’s financial statements or included in a filing with the Securities Exchange Commission.

•“Incentive-Based Compensation” means any compensation that is granted, earned, or vested based wholly or in part upon the attainment of a Financial Reporting Measure. Incentive-Based Compensation is “received” for purposes of this Policy in the Company’s fiscal period during which the Financial Reporting Measure specified in the Incentive-Based Compensation award is attained, even if the payment or grant of such Incentive-Based Compensation occurs after the end of that period.

3.Covered Executives; Incentive-Based Compensation

This Policy applies to Incentive-Based Compensation received by a Covered Executive (a) after beginning services as a Covered Executive; (b) if that person served as a Covered Executive at any time during the performance period for such Incentive-Based

2

Compensation; and (c) while the Company had a listed class of securities on a national securities exchange.

4.Required Recoupment of Erroneously Awarded Compensation in the Event of an Accounting Restatement

In the event the Company is required to prepare an Accounting Restatement, the Company shall promptly recoup the amount of any Erroneously Awarded Compensation received by any Covered Executive, as calculated pursuant to Section 5 hereof, during the Applicable Period.

5.Erroneously Awarded Compensation: Amount Subject to Recovery

The amount of “Erroneously Awarded Compensation” subject to recovery under the Policy, as determined by the Administrator, is the amount of Incentive-Based Compensation received by the Covered Executive that exceeds the amount of Incentive-Based Compensation that would have been received by the Covered Executive had it been determined based on the restated amounts.

Erroneously Awarded Compensation shall be computed by the Administrator without regard to any taxes paid by the Covered Executive in respect of the Erroneously Awarded Compensation.

By way of example, with respect to any compensation plans or programs that take into account Incentive-Based Compensation, the amount of Erroneously Awarded Compensation subject to recovery hereunder includes, but is not limited to, the amount contributed to any notional account based on Erroneously Awarded Compensation and any earnings accrued to date on that notional amount.

For Incentive-Based Compensation based on stock price or TSR: (a) the Administrator shall determine the amount of Erroneously Awarded Compensation based on a reasonable estimate of the effect of the Accounting Restatement on the stock price or TSR upon which the Incentive-Based Compensation was received; and (b) the Company shall maintain documentation of the determination of that reasonable estimate and provide such documentation to the New York Stock Exchange (the “NYSE”).

6.Method of Recoupment

The Administrator shall determine, in its sole discretion, the timing and method for promptly recouping Erroneously Awarded Compensation hereunder, which may include, without limitation (a) seeking reimbursement of all or part of any cash or equity-based award, (b) cancelling prior cash or equity-based awards, whether vested or unvested or paid or unpaid, (c) canceling or offsetting against any planned future cash or equity-based awards, (d) forfeiture of deferred compensation, subject to compliance with Section 409A of the Internal Revenue Code and the regulations promulgated thereunder, and (e) any other method authorized by applicable law or contract. Subject to compliance with any applicable law, the Administrator may affect recovery under this Policy from any amount otherwise payable to the Covered Executive, including amounts payable to such individual under any otherwise applicable Company plan or program, including base salary, bonuses or commissions and compensation previously deferred by the Covered Executive.

3

The Company is authorized and directed pursuant to this Policy to recoup Erroneously Awarded Compensation in compliance with this Policy unless the Compensation Committee of the Board has determined that recovery would be impracticable solely for the following limited reasons, and subject to the following procedural and disclosure requirements:

•The direct expense paid to a third party to assist in enforcing the Policy would exceed the amount to be recovered. Before concluding that it would be impracticable to recover any amount of Erroneously Awarded Compensation based on expense of enforcement, the Administrator must make a reasonable attempt to recover such erroneously awarded compensation, document such reasonable attempt(s) to recover, and provide that documentation to the NYSE;

•Recovery would violate home country law of the issuer where that law was adopted prior to November 28, 2022. Before concluding that it would be impracticable to recover any amount of Erroneously Awarded Compensation based on violation of home country law of the issuer, the Administrator must satisfy the applicable opinion and disclosure requirements of Rule 10D-1 and the Listing Standards; or

•Recovery would likely cause an otherwise tax-qualified retirement plan, under which benefits are broadly available to employees of the Company, to fail to meet the requirements of 26 U.S.C. 401(a)(13) or 26 U.S.C. 411(a) and regulations thereunder.

7.No Indemnification of Covered Executives

Notwithstanding the terms of any indemnification or insurance policy or any contractual arrangement with any Covered Executive that may be interpreted to the contrary, the Company shall not indemnify any Covered Executives against the loss of any Erroneously Awarded Compensation, including any payment or reimbursement for the cost of third-party insurance purchased by any Covered Executives to fund potential clawback obligations under this Policy.

8.Administrator Indemnification

Any members of the Administrator, and any other members of the Board who assist in the administration of this Policy, shall not be personally liable for any action, determination or interpretation made with respect to this Policy and shall be fully indemnified by the Company to the fullest extent under applicable law and Company policy with respect to any such action, determination or interpretation. The foregoing sentence shall not limit any other rights to indemnification of the members of the Board under applicable law or Company policy.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Basis of Presentation

The accompanying consolidated financial statements include the accounts of Spirit Airlines, Inc. ("Spirit") and its consolidated subsidiaries (the "Company"). Spirit is an ultra low-cost, low-fare airline that provides affordable travel opportunities principally throughout the domestic United States, the Caribbean and Latin America and is headquartered in Miramar, Florida. Spirit manages operations on a system-wide basis due to the interdependence of its route structure in the various markets served. As only one service is offered (i.e., air transportation), management has concluded there is only one reportable segment.

Use of Estimates

The preparation of financial statements in accordance with generally accepted accounting principles in the United States of America requires the Company's management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The Company's estimates and assumptions are based on historical experience and changes in the business environment. However, actual results may differ from estimates under different conditions, sometimes materially.

Cash and Cash Equivalents

The Company considers all highly liquid investments with maturities of less than three months at the date of acquisition to be cash equivalents. Investments included in this category primarily consist of cash and money market funds. Cash and cash equivalents are stated at cost, which approximates fair value.

Restricted Cash

The Company's restricted cash is comprised of cash held in account subject to account control agreements to be used for the payment of interest and fees on the Company's 8.00% senior secured notes and cash pledged as collateral against the Company's secured letters of credit.

Short-term Investment Securities

The Company's short-term investment securities are classified as available-for-sale and generally consist of U.S. Treasury and U.S. government agency securities with contractual maturities of twelve months or less. These securities are stated at fair value within current assets on the Company's consolidated balance sheet. For all short-term investments, at each reset period or upon reinvestment, the Company accounts for the transaction as proceeds from the maturity of short-term investment securities for the security relinquished, and purchase of short-term investment securities for the security purchased, in the Company's consolidated statements of cash flows. Realized gains and losses on sales of investments, if any, are reflected in non-operating other (income) expense in the consolidated statements of operations. Unrealized gains and losses on investment securities are reflected as a component of accumulated other comprehensive income.

Accounts Receivable

Accounts receivable primarily consist of amounts due from credit card processors associated with the sales of tickets, amounts due from the Internal Revenue Service related to federal excise fuel tax and amounts expected to be received related to the CARES Employee Retention credit. The Company records an allowance for amounts not expected to be collected. The Company estimates the allowance based on historical write-offs and aging trends as well as an estimate of the expected lifetime credit losses. The allowance for doubtful accounts was immaterial as of December 31, 2023 and 2022.

In addition, the provision for doubtful accounts and write-offs for 2023, 2022 and 2021 were each immaterial.

Income Tax Receivable

Income tax receivable consists of amounts due from tax authorities for recovery of income taxes paid in prior periods.

Property and Equipment

Property and equipment is stated at cost, less accumulated depreciation and amortization. Depreciation of operating property and equipment is computed using the straight-line method applied to each unit of property. Residual values for new aircraft, new engines, major spare rotable parts, avionics and assemblies are generally estimated to be 10%. Property under

finance leases and related obligations are initially recorded at an amount equal to the present value of future minimum lease payments computed using the Company's incremental borrowing rate or, when known, the interest rate implicit in the lease. Amortization of property under finance leases is recorded on a straight-line basis over the lease term and is included in depreciation and amortization expense.

The depreciable lives used for the principal depreciable asset classifications are:

	Estimated Useful Life
Aircraft, engines and flight simulators	25
Spare rotables and flight assemblies	7 to 25 years
Other equipment and vehicles	5 to 7 years
Internal use software	3 to 10 years
Finance leases	Lease term or estimated useful life of the asset
Leasehold improvements	Lesser of lease term or estimated useful life of the improvement
Buildings	Lesser of lease term or 30 years

As of December 31, 2023, the Company had 88 aircraft (including 15 aircraft that would have been deemed finance leases resulting in failed sale-leaseback transactions), 28 spare engines and 3 flight simulators capitalized within flight equipment with depreciable lives of 25 years. As of December 31, 2023, the Company had 117 aircraft financed through operating leases with lease terms from 4 years to 18 years. In addition, the Company had 6 spare engines financed through operating leases with lease terms from 12 years to 18 years.

    The following table illustrates the components of depreciation and amortization expense:

	Year Ended December 31,
	2023		2022		2021
	(in thousands)
Depreciation	$	218,106	$	199,118	$	193,079
Amortization of heavy maintenance	79,768		96,707		91,929
Amortization of capitalized software	22,998		17,265		12,203
Total depreciation and amortization	$	320,872	$	313,090	$	297,211

The Company capitalizes certain internal and external costs associated with the acquisition and development of internal-use software for new products, and enhancements to existing products, that have reached the application development stage and meet recoverability tests. Capitalized costs include external direct costs of materials and services utilized in developing or obtaining internal-use software, and labor cost for employees who are directly associated with, and devote time, to internal-use software projects. Capitalized computer software, included as a component of ground and other equipment in the accompanying consolidated balance sheets, net of amortization, was $53.6 million and $41.1 million at December 31, 2023 and 2022, respectively.

The Company accounts for heavy maintenance and major overhaul under the deferral method whereby the cost of heavy maintenance and major overhaul is deferred and amortized until the earlier of the end of the useful life of the related asset, the end of the remaining lease term or the next scheduled heavy maintenance event.

The Company records amortization of capitalized software on a straight-line basis within depreciation and amortization expense in the accompanying consolidated statements of operations. The Company placed in service internal-use software of $35.5 million, $25.7 million and $20.5 million, during the years ended 2023, 2022 and 2021, respectively.

Operating Lease Right-of-Use Asset and Liabilities

Right-of-use assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. Right-of-use assets and lease liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. When available, the Company uses the rate implicit in the lease to discount lease payments to present value. However, the Company's leases generally do not provide a readily determinable implicit rate. Therefore, the Company estimates the incremental borrowing rate to discount lease payments based on information available at lease commencement. The Company uses publicly available data for instruments with similar characteristics when calculating its incremental borrowing rates. The Company has options to extend certain of its operating leases for an additional period of time and options to early terminate several of its

operating leases. The lease term consists of the noncancellable period of the lease, periods covered by options to extend the lease if the Company is reasonably certain to exercise the option, periods covered by an option to terminate the lease if the Company is reasonably certain not to exercise the option and periods covered by an option to extend or not terminate the lease in which the exercise of the option is controlled by the lessor. The Company's lease agreements do not contain any residual value guarantees. The Company elected to not separate non-lease components from the associated lease component for all underlying classes of assets with lease and non-lease components.

The Company elected not to apply the recognition requirements in Topic 842 to short-term leases (i.e., leases of 12 months or less) but instead recognize these lease payments in income on a straight-line basis over the lease term. The Company elected this accounting policy for all classes of underlying assets. In addition, in accordance with Topic 842, variable lease payments are not included in the recognition of a lease liability or right-of-use asset.

Pre-Delivery Deposits on Flight Equipment

The Company is required to make pre-delivery deposit payments ("PDPs") towards the purchase price of each new aircraft and engine prior to the scheduled delivery date. These deposits are initially classified as pre-delivery deposits on flight equipment on the Company's consolidated balance sheets until the aircraft or engine is delivered, at which time the related PDPs are deducted from the final purchase price of the aircraft or engine and are reclassified to flight equipment on the Company's consolidated balance sheets.

In addition, the Company capitalizes the interest that is attributable to the outstanding PDP balances as a percentage of the related debt on which interest is incurred. Capitalized interest represents interest cost incurred during the acquisition period of a long-term asset, and is the amount which theoretically could have been avoided had the Company not paid PDPs for the related aircraft or engines.

Related interest is capitalized and included within pre-delivery deposits on flight equipment through the acquisition period until delivery is taken of the aircraft or engine and the asset is ready for service. Once the aircraft or engine is delivered, the capitalized interest is also reclassified into flight equipment on the Company's consolidated balance sheets along with the related PDPs as they are included in the cost of the aircraft or engine. Capitalized interest for 2023, 2022 and 2021 was primarily related to the interest incurred on long-term debt.

Measurement of Asset Impairments

The Company records impairment charges on long-lived assets used in operations when events and circumstances indicate that the assets may be impaired, the undiscounted future cash flows estimated to be generated by those assets are less than the carrying amount of those assets, and the net book value of the assets exceeds their estimated fair value. Factors which could be indicators of impairment include but are not limited to (1) a decision to permanently remove flight equipment or other long-lived assets from operations, (2) significant changes in the estimated useful life, (3) significant changes in projected cash flows, (4) permanent and significant declines in related fair values and (5) changes to the regulatory environment. In making these determinations, the Company uses certain assumptions, including, but not limited to: (i) estimated fair value of the assets; and (ii) estimated, undiscounted future cash flows expected to be generated by these assets, which are based on additional assumptions such as asset utilization, length of service the asset will be used in the Company’s operations, and estimated salvage values.

During 2023, the Company did not recognize impairment-related charges. During the fourth quarter of 2022, the Company made the decision to accelerate the retirement of 29 of its A319 aircraft, which were owned and unencumbered, as of December 31, 2022. In January 2023, the Company executed a purchase agreement to sell these aircraft over the next two years. The Company concluded that Management’s plan to early retire and ultimately sell these 29 A319 aircraft is an impairment indicator which required the Company to test the recoverability of the related asset group as of December 31, 2022. No impairment indicators existed and no charges were necessary under applicable accounting standards as of December 31, 2022, for the remaining flight equipment, which together represent one asset group.

The Company concluded that the net book value of this specific asset group of owned A319 aircraft is not recoverable as of December 31, 2022, due to changes to the estimated future cash flows primarily driven by the significant reductions to their remaining operating lives. As a result, during 2022, the Company recognized $333.7 million in impairment-related charges for the amount by which the carrying amount of this asset group, including the related net capitalized maintenance, exceeded its estimated fair value. During 2022, the impairment charges were recorded within special charges (credits) in the Company’s consolidated statement of operations. The fair values of these assets were determined using Level 3 fair value inputs primarily based on the agreed upon sales price for each aircraft, adjusted for estimated utilization in the period of operation from December 31, 2022 to the expected future sales date. For additional information, refer to Note 4, Special Charges and Credits.

Passenger Revenues

    Fare revenues. Tickets sold are initially deferred within air traffic liability ("ATL") on the Company's consolidated balance sheet. Passenger fare revenues are recognized at time of departure when transportation is provided. Generally, all tickets sold by the Company are nonrefundable. As of December 31, 2023 and 2022, the Company had ATL balances of $383.8 million and $429.6 million, respectively. As of December 31, 2023, substantially all of the ATL balance as of December 31, 2022 had been recognized. Substantially all of the Company's ATL balance as of December 31, 2023 is expected to be recognized within 12 months.

Non-fare revenues. Non-fare revenues is primarily comprised of certain ancillary items such as bags, seats and other travel-related fees, which are deemed part of the single performance obligation of providing passenger transportation. These ancillary items are recognized in non-fare revenues within passenger revenues, at the time of departure. In addition, non-fare revenues related to other travel-related programs and services provided are recognized as deemed appropriate.

The following table shows disaggregated operating revenues for the twelve months ended December 31, 2023, 2022 and 2021:

	Twelve Months Ended December 31,
	2023		2022		2021
	(in thousands)
Operating revenues:
Fare	$	2,338,191	$	2,455,817	$	1,422,927
Non-fare	2,929,970		2,533,548		1,752,875
Total passenger revenues	5,268,161		4,989,365		3,175,802
Other	94,388		79,082		54,973
Total operating revenues	$	5,362,549	$	5,068,447	$	3,230,775

Changes and cancellations. An unused ticket expires at the date of scheduled travel, at which time a service charge is assessed, and is recognized as revenue at the date of scheduled travel. However, customers may elect to change or cancel their itinerary prior to the date of departure. For changes, a service charge is recognized at time of departure of newly scheduled travel and is deducted from the face value of the original purchase price of the ticket, and the original ticket becomes invalid. For cancellations, a service charge is assessed and the amount remaining after deducting the service charge is called a credit shell which generally expires 90 days from the date the credit shell is created. Credit shells can be used towards the purchase of a new ticket and the Company’s other service offerings. Both service charge and credit shell amounts are recorded as deferred revenue and amounts expected to expire unused are estimated based on historical experience.

Estimating the amount of credits that will go unused involves some level of subjectivity and judgment. Assumptions used to generate breakage estimates can be impacted by several factors including, but not limited to, changes to the Company's ticketing policies, changes to the Company’s refund, exchange, and credit shell policies, and economic factors. The amount of credit shells issued varies, primarily due to the flight delays and cancellation events throughout the year. The Company generally experiences some variability in the amount of breakage revenue recognized throughout the year and expects some variability in the amount of breakage revenue recorded in future periods, as the estimates of the portion of those funds that will expire unused may differ from historical experience.

Other Revenues

Other revenues primarily consist of the marketing component of the sale of loyalty points to the Company's credit card partner and commissions revenue from the sale of various items such as hotels and rental cars.

Loyalty Program

The Company operates the Free Spirit loyalty program (the "Free Spirit Program"), which attracts members and partners and builds customer loyalty for the Company by offering a variety of awards, benefits and services. Free Spirit Program members earn and accrue points for dollars spent on Spirit for flights and other non-fare services as well as services from non-air partners such as retail merchants, hotels or car rental companies or by making purchases with credit cards issued by partner banks and financial services providers. Points are redeemable by customers in future periods for air travel on Spirit.

    To reflect the point credits earned, the program includes two types of transactions that are considered revenue arrangements with multiple performance obligations: (1) points earned with travel and (2) points sold to its co-branded credit card partner.

    Passenger ticket sales earning points. Passenger ticket sales earning points provide customers with (1) points earned and (2) air transportation. The Company values each performance obligation on a stand-alone basis and allocates the consideration to each performance obligation based on their relative fair value. To value the point credits earned, the Company considers the quantitative value a passenger receives by redeeming points for a ticket rather than paying cash, which is referred to as equivalent ticket value ("ETV").

The Company defers revenue for the points when earned and recognizes loyalty travel awards in passenger revenue as the points are redeemed and services are provided. The Company records the air transportation portion of the passenger ticket sales in air traffic liability and recognizes passenger revenue when transportation is provided or if the ticket goes unused, at the date of scheduled travel.

    Sale of points. Customers may earn points based on their spending with the Company's co-branded credit card company with which the Company has an agreement to sell points. The contract to sell points under this agreement has multiple performance obligations, as discussed below.

The Company's co-branded credit card agreement provides for joint marketing where cardholders earn points for making purchases using co-branded cards. During 2023, the Company extended its agreement with the administrator of the Free Spirit affinity credit card program through December 31, 2028. The Company accounts for this agreement consistently with the accounting method that allocates the consideration received to the individual products and services delivered. The value is allocated based on the relative stand-alone selling prices of those products and services, which generally consists of (i) points to be awarded, (ii) airline benefits, (iii) licensing of brand and access to member lists and (iv) advertising and marketing efforts. The Company determined the estimate of the stand-alone selling prices by considering discounted cash flow analysis using multiple inputs and assumptions, including: (1) the expected number of points awarded and number of points redeemed, (2) the estimated stand-alone selling price of the award travel obligation and airline benefits, (3) licensing of brand access to member lists and (4) the cost of advertising and marketing efforts undertaken by the Company.

The Company defers the amount for award travel obligation as part of loyalty deferred revenue. These amounts that are expected to be redeemed during the following twelve months are recorded within ATL on the consolidated balance sheet and the portion that is not expected to be redeemed during the following twelve months is recorded within long-term liabilities on the consolidated balance sheet. In addition, the Company recognizes loyalty travel awards in passenger revenue as the points are used for travel. Revenue allocated to advertising and the remaining performance obligations, primarily marketing components, is recorded in other revenue over time as points are delivered. Total unrecognized revenue from future Free Spirit Program was $104.6 million and $81.3 million at December 31, 2023 and 2022, respectively. The current portion of this balance is recorded within air traffic liability and the long-term portion of this balance is recorded within deferred gains and other long-term liabilities in the accompanying consolidated balance sheets.

    The following table illustrates total cash proceeds received from the sale of points and the portion of such proceeds recognized in non-ticket revenue immediately as marketing component:

	Consideration received from credit card loyalty programs		Portion of proceeds recognized immediately as marketing component
Year Ended	(in thousands)
December 31, 2023	$	93,147	$	48,071
December 31, 2022	80,970		40,987
December 31, 2021	48,035		23,681

    Points breakage. For points that the Company estimates are not likely to be redeemed ("breakage"), the Company recognizes the associated value proportionally during the period in which the remaining points are redeemed. Management uses statistical models to estimate breakage based on historical redemption patterns. A change in assumptions as to the period over which points are expected to be redeemed, the actual redemption activity for points or the estimated fair value of points expected to be redeemed could have an impact on revenues in the year in which the change occurs and in future years.

    Current activity of loyalty program. Points are combined in one homogeneous pool and are not separately identifiable. As such, revenue is composed of points that were part of the loyalty deferred revenue balance at the beginning of the period as well as points that were issued during the period.

Airframe and Engine Maintenance

The Company accounts for heavy maintenance and major overhaul under the deferral method whereby the cost of heavy maintenance and major overhaul is deferred and amortized until the earlier of the end of the useful life of the related asset, the end of the remaining lease term or the next scheduled heavy maintenance event.

Amortization of heavy maintenance and major overhaul costs charged to depreciation and amortization expense was $79.8 million, $96.7 million and $91.9 million for the years ended 2023, 2022 and 2021, respectively. During the years ended 2023, 2022 and 2021, the Company deferred $202.9 million, $149.3 million and $74.1 million, respectively, of costs for heavy maintenance. As of December 31, 2023 and 2022, the Company had a deferred heavy maintenance balance of $529.8 million and $349.0 million, and accumulated heavy maintenance amortization of $216.2 million and $158.6 million, respectively.

The Company outsources certain routine, non-heavy maintenance functions under contracts that require payment on a utilization basis, primarily based on flight hours. Costs incurred for maintenance and repair under flight hour maintenance contracts, where labor and materials price risks have been transferred to the service provider, are expensed based on contractual payment terms. All other costs for routine maintenance of the airframes and engines are charged to expense as performed.

The table below summarizes the components of the Company’s maintenance cost:

	Year Ended December 31,
	2023		2022		2021
	(in thousands)
Utilization-based maintenance expense	$	117,458	$	97,930	$	81,591
Non-utilization-based maintenance expense	105,881		89,890		77,911
Total maintenance, materials and repairs	$	223,339	$	187,820	$	159,502

Leased Aircraft Return Costs

The Company's aircraft lease agreements often contain provisions that require the Company to return aircraft airframes, engines and other aircraft components to the lessor in a certain condition or pay an amount to the lessor based on the airframe and engine's actual return condition. Lease return costs include all costs that would be incurred at the return of the aircraft, including costs incurred to repair the airframe and engines to the required condition as stipulated by the lease. Lease return costs are recognized beginning when it is probable that such costs will be incurred and they can be estimated.

When determining the probability to accrue lease return costs, there are various estimated cost and factors which need to be considered such as the contractual terms of the lease agreement, current condition of the aircraft, the age of the aircraft at lease expiration, projected number of hours run on the engine at the time of return, and the number of projected cycles run on the airframe at the time of return, among others. Management assesses the need to accrue lease return costs periodically throughout the year or whenever facts and circumstances warrant an assessment. Lease return costs will generally be estimable closer to the end of the lease term but may be estimable earlier in the lease term depending on the contractual terms of the lease agreement and the timing of maintenance events for a particular aircraft.

Aircraft Fuel

Aircraft fuel expense includes jet fuel and associated into-plane costs, taxes, and oil, and realized and unrealized gains and losses associated with fuel derivative contracts, if any.

Advertising

The Company expenses advertising and the production costs of advertising as incurred. Marketing and advertising expenses of $9.0 million, $9.2 million and $7.1 million for the years ended 2023, 2022 and 2021, respectively, were recorded within distribution expense in the consolidated statements of operations.

Income Taxes

The Company accounts for income taxes using the asset and liability method. The Company records a valuation allowance to reduce the deferred tax assets reported if, based on the weight of the evidence, it is more likely than not that some

portion or all of the deferred tax assets will be not realized. As of December 31, 2023 and 2022, the Company had a valuation allowance of $17.7 million and $10.9 million, respectively, recorded within deferred income taxes on the Company's consolidated balance sheets. For additional information, refer to Note 16, Income Taxes.

Stock-Based Compensation

The Company recognizes cost of employee services received in exchange for awards of equity instruments based on the fair value of each instrument at the date of grant. For the majority of awards, compensation expense is recognized on a straight-line basis over the period during which an employee is required to provide service in exchange for an award. Certain awards have performance conditions that must be achieved prior to vesting and are expensed based on the expected achievement at each reporting period. The Company has issued restricted stock awards, performance share awards, market share awards and performance and market share awards. Restricted stock awards are valued at the fair value of the shares on the date of grant. The fair value of performance share awards based on a market condition and the market share awards are estimated through the use of a Monte Carlo simulation model. The fair value of performance share awards based on a performance condition is based on the fair value of the shares on the date of grant. The performance share awards based on a performance condition are evaluated at each report date and adjustments are made to stock-based compensation expense based on the number of shares deemed probable of issuance upon vesting. The fair value of the market and performance share awards are estimated through the use of a Monte Carlo simulation model and adjusted based on the number of shares deemed probable of issuance upon vesting. For additional information, refer to Note 11, Stock-Based Compensation.

Payroll Support Program

During 2020 and 2021, in order to assist the Company to pay for salaries, wages and benefits for its employees, the Company entered into three separate Payroll Support Program Agreements under the CARES Act (“PSP1”), as extended by the Consolidated Appropriations Act of 2021 (“PSP2”) and the American Rescue Plan Act (“PSP3”) with the Treasury. The agreements provided the Company with grants (refer to Note 4, Special Charges and Credits for additional information), unsecured term loans (refer to Note 13, Debt and Other Obligations for additional information) and warrants (refer to Note 10, Equity for additional information). The funds provided were used exclusively to pay for salaries, wages and benefits for the Company's employees. As of December 31, 2023, the Company is in compliance with the terms of the PSP1, PSP2 and PSP3.

Concentrations of Risk

The Company’s business may be adversely affected by increases in the price of aircraft fuel, the volatility of the price of aircraft fuel, or both. Aircraft fuel, one of the Company’s largest expenditures, represented approximately 31%, 34% and 28% of total operating expenses in 2023, 2022 and 2021, respectively.

The Company’s operations are largely concentrated in the southeast United States with Fort Lauderdale being the highest volume fueling point in the system. Gulf Coast Jet indexed fuel is the basis for a substantial majority of the Company’s fuel consumption. Any disruption to the oil production or refinery capacity in the Gulf Coast, as a result of weather or any other disaster, or disruptions in supply of jet fuel, dramatic escalations in the costs of jet fuel and/or the failure of fuel providers to perform under fuel arrangements for other reasons could have a material adverse effect on the Company’s financial condition and results of operations.

The Company’s operations will continue to be vulnerable to weather conditions (including hurricane season or snow and severe winter weather), which could disrupt service or create air traffic control problems. These events may result in decreased revenue and/or increased costs.

The Company relies on a limited number of vendors for the delivery of additional aircraft and engines - currently Airbus A320-family, single-aisle aircraft, powered by engines manufactured by IAE and Pratt & Whitney. Due to the relatively small size of the Company's fleet and high utilization rate, the unavailability of aircraft and engines, as well as the reduced capacity, resulting from delivery delays or performance issues from these vendors, could have a material adverse effect on the Company’s business, results of operations and financial condition. Refer to Note 3, Current Developments, for additional information on the Pratt & Whitney engine performance issues.

As of December 31, 2023, the Company had six union-represented employee groups that together represented approximately 85% of all employees. The Company's aircraft maintenance technicians are represented by AMFA. The related collective bargaining agreement is currently under negotiation. A strike or other significant labor dispute with the Company’s unionized employees is likely to adversely affect the Company’s ability to conduct business. Additional disclosures are included in Note 17, Commitments and Contingencies.

JetBlue Merger

On July 28, 2022, Spirit entered into an Agreement and Plan of Merger (the “Merger Agreement”) with JetBlue Airways Corporation, a Delaware corporation (“JetBlue”), and Sundown Acquisition Corp., a Delaware corporation and a direct, wholly owned subsidiary of JetBlue (“Merger Sub”), pursuant to which and subject to the terms and conditions therein, Merger Sub will merge with and into Spirit, with Spirit continuing as the surviving entity (the “Merger”). As a result of the Merger, each outstanding share of Spirit's common stock (except for dissenting shares, treasury stock, and shares of Spirit's common stock owned by JetBlue, Merger Sub or any of their respective wholly owned subsidiaries), will be converted into the right to receive an amount in cash per share, without interest, equal to (such amount, the “Merger Consideration”) (i) $33.50 minus (ii) (A) $2.50 (the “Approval Prepayment Amount”), paid on October 26, 2022 following the adoption by Spirit stockholders of the Merger Agreement on October 19, 2022 and (B) an additional monthly per share prepayment amount calculated as the product of $0.10 and the number of additional prepayments paid (or, in the event the Closing occurs after the record date of, but before the payment date of any such additional prepayment, to the extent payable after the Closing), not to exceed $1.15 per share of Spirit common stock, by JetBlue to Spirit stockholders in accordance with the Merger Agreement (each such payment is referred to as an “Additional Prepayment” and such $0.10 amount is referred to as the “Additional Prepayment Amount”). If an aggregate of $1.15 of Additional Prepayment Amounts has been paid out before consummation or termination of the Merger, Spirit stockholders will thereafter continue to receive monthly Additional Prepayments, at the same $0.10 per month rate, until the transaction closes or the Merger Agreement is terminated. The Merger Agreement becomes unilaterally terminable by either JetBlue or Spirit after July 24, 2024.

In accordance with the terms of the Merger Agreement, JetBlue is required to pay or cause to be paid the Approval Prepayment Amount to Spirit stockholders as of the record date established by Spirit for the special meeting to approve the Merger Agreement within five business days following such Spirit stockholder approval. Thereafter, on or prior to the last business day of each month beginning after December 31, 2022 until the earlier of the Closing or termination of the Merger Agreement, JetBlue will also pay or cause to be paid the Additional Prepayment Amount to Spirit stockholders as of a record date not more than five business days prior to the last business day of such month. Payments made from JetBlue to Spirit stockholders do not impact the Company's results of operations or cash flows.

On October 19, 2022, Spirit’s stockholders approved the Merger Agreement at a special meeting of stockholders. The record date for both the Company’s special meeting and the Approval Prepayment was September 12, 2022. In accordance with the terms of the Merger Agreement, on October 26, 2022, JetBlue paid the Spirit stockholders the Approval Prepayment Amount of $2.50 per share. Additionally, beginning January 2023, JetBlue paid on a monthly basis the Additional Prepayments of $0.10 per share of common stock to all Spirit stockholders as of each record date, per the Merger Agreement.

Due to the payment of the Approval Prepayment and each of the Additional Prepayment Amounts, in accordance with the terms of the respective debt indentures and warrant agreements, the Company announced related adjustments to the conversion rates of its convertible notes due 2025 and its convertible notes due 2026 as well as adjustments to the exercise prices and warrant shares of the PSP1, PSP2 and PSP3 warrants outstanding. As of December 31, 2023, the conversion rates of the convertible notes due 2025 and 2026 were 94.9262 and 24.6649 shares of voting common stock per $1,000 principal

amount of convertible notes, respectively. In addition, as of December 31, 2023, the exercise prices of the PSP1, PSP2 and PSP3 warrants were $11.663, $20.229 and $30.196, respectively, and the number of warrant shares issuable upon the exercise of the PSP1, PSP2 and PSP3 warrants were adjusted to 628,725.19, 166,292.37 and 97,219.73, respectively.

Completion of the Merger is subject to the satisfaction or waiver of certain closing conditions, including, among other things: (1) approval of the transactions by Spirit’s stockholders, which was received on October 19, 2022; (2) receipt of applicable regulatory approvals, including approvals from the U.S. Federal Communications Commission, the U.S. Federal Aviation Administration and the U.S. Department of Transportation ("DOT") and the expiration or early termination of the statutory waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and other competition laws, and other required regulatory approvals; (3) the absence of any law or order prohibiting the consummation of the transactions; and (4) the absence of any material adverse effect (as defined in the Merger Agreement) on Spirit.

On March 7, 2023, the U.S. Department of Justice (“DOJ”) filed suit to block the Merger and a trial was held in late 2023. On January 16, 2024, the United States District Court for the District of Massachusetts (the “District Court”) granted a permanent injunction against the Merger (the "Injunction"). On January 19, 2024, Spirit and JetBlue filed a notice of appeal to reverse the District Court's decision and allow Spirit and JetBlue to complete the Merger. On January 25, 2024, JetBlue made a public filing stating that certain closing conditions required by the Merger Agreement may not be satisfied prior to the outside dates set forth in the Merger Agreement and, accordingly, the Merger Agreement may be terminable on and after January 28, 2024. The Company does not believe there is a basis for terminating the Merger Agreement, and will continue to abide by all of its obligations under the Merger Agreement. On January 29, 2024, Spirit and JetBlue filed a request with the U.S. Court of Appeals for the First Circuit (the "Court of Appeals") seeking an expedited schedule for their appeal. On February 2, 2024, the Court of Appeals granted our motion, stating it would hear arguments in June 2024.

In addition, Spirit has agreed, among other things, that neither it nor any of its directors, officers, employees and representatives will (1) solicit alternative transactions, (2) participate in any discussions or negotiations relating to alternative transactions, (3) furnish any non-public information in connection with alternative transactions or (4) enter into any agreement relating to alternative transactions, except under limited circumstances described in the Merger Agreement. However, in certain circumstances, Spirit may terminate the Merger Agreement to enter into a definitive agreement for a Superior Proposal (as defined in the Merger Agreement). In addition, Spirit, JetBlue and Merger Sub each make certain customary representations, warranties and covenants, as applicable, in the Merger Agreement.

The Merger Agreement contains certain termination rights for Spirit and JetBlue, including, without limitation, a right for either party to terminate if the Merger is not consummated on or before July 28, 2023 (the "Outside Date"), subject to certain automatic extensions up to July 24, 2024 if needed to obtain regulatory approvals. Since all regulatory approvals required to consummate the Merger were not obtained as of July 28, 2023 and January 28, 2024, the current Outside Date has been automatically extended to July 24, 2024. Upon the termination of the Merger Agreement under specified circumstances, Spirit will be required to pay JetBlue a termination fee of $94.2 million. Upon the termination of the Merger Agreement by JetBlue because of a material uncured breach by Spirit of the Merger Agreement, Spirit will be required to pay JetBlue an amount equal to the sum of all amounts paid by JetBlue to the Spirit stockholders. Upon the termination of the Merger Agreement for failure to obtain antitrust regulatory clearance, JetBlue will be required to pay (i) to Spirit, $70.0 million, and (ii) to the Spirit stockholders, the excess of (A) $400.0 million minus (B) the sum of the Approval Prepayment Amount and all Additional Prepayment Amounts previously paid by JetBlue to the Spirit stockholders.

Pratt & Whitney

On July 25, 2023, RTX Corporation, parent company of Pratt & Whitney, announced that it had determined that a rare condition in the powdered metal used to manufacture certain engine parts will require accelerated inspection of the PW1100G-JM ("GTF") fleet, which powers the Company's A320neo family of aircraft.

In September 2023, Pratt & Whitney notified the Company that all the GTF neo engines in its fleet, including the engines slotted for future aircraft deliveries, for a yet to be determined period, are subject to the inspection and possible replacement, of the powdered metal high-pressure turbine and compressor discs. In addition, Pratt & Whitney issued a special instruction ("SI"), requiring accelerated engine removals and inspections covering the initial tranche of operational engines, no later than September 15, 2023. As of December 31, 2023, in accordance with the SI issued by Pratt & Whitney, the Company has removed five engines from service, three of which are currently awaiting induction for inspection. For the remaining engines, Pratt & Whitney has provided an initial analysis on an inspection and removal schedule for these engines.

In addition, to the 5 engines removed from service, the Company had 12 neo aircraft grounded as of December 31, 2023 for reliability, durability, and inspection requirements combined. The Company currently estimates the majority of the affected

engines will require removal and inspection in 2024, but continuing through 2026, based on service bulletins ("SB") issued by Pratt & Whitney and related airworthiness directives issued by the FAA.

The temporary removal of engines from service is expected to drive a significant decrease in the Company's near-term growth projections. The Company has reduced capacity in amounts and timing commensurate with the initially scheduled removal and inspection of these impacted engines, however, the Company continues to assess the impact on its future capacity plans. Pratt & Whitney stated that they are focused on addressing the challenges arising from the powdered metal manufacturing issue and will proactively take steps to support and mitigate the operational impact to its customers. The Company has begun discussions with Pratt & Whitney regarding compensation for the loss of utilization; however, the amount, timing, or structure of the compensation that will be agreed upon is not yet known.

Credit Card Processing Arrangements

7.Credit Card Processing Arrangements

The Company has agreements with organizations that process credit card transactions arising from the purchase of air travel, baggage charges and other ancillary services by customers. As it is standard in the airline industry, the Company's contractual arrangements with credit card processors permit them, under certain circumstances, to retain a holdback or other collateral, when future air travel and other future services are purchased via credit card transactions. The required holdback is the percentage of the Company's overall credit card sales that its credit card processors hold to cover refunds to customers if the Company fails to fulfill its flight obligations.

The Company's credit card processors do not require the Company to maintain cash collateral provided that the Company satisfies certain liquidity and other financial covenants. Failure to meet these covenants would provide the processors the right to place a holdback, resulting in a commensurate reduction of unrestricted cash. As of December 31, 2023 and 2022, the Company was in compliance with such liquidity and other financial covenants in its credit card processing agreements, and the processors were holding back no remittances.

The maximum potential exposure to cash holdbacks by the Company's credit card processors, based upon advance ticket sales and Spirit Saver$ Club® memberships as of December 31, 2023 and 2022, was $408.3 million and $468.5 million, respectively.

Voting Rights. Each holder of the Company’s common stock is entitled to one vote for each share on all matters submitted to a vote of the stockholders, including the election of directors. The Company’s stockholders do not have cumulative voting

Share-Based Payment Arrangement [Abstract]

Stock-Based Compensation

Stock-Based Compensation

The Company has stock plans under which directors, officers, key employees and consultants of the Company may be granted restricted stock, stock options, performance share awards and other equity-based instruments as a means of promoting the Company’s long-term growth and profitability. The plans are intended to encourage participants to contribute to, and participate in the success of the Company.

On December 16, 2014, the Company's Board of Directors approved the 2015 Incentive Award Plan, or 2015 Plan, which was subsequently approved by the Company's stockholders on June 16, 2015. On March 10, 2021, the Company's Board of Directors approved an amendment of the Company's 2015 Incentive Award Plan to increase the number of authorized shares of common stock available for issuance by 3.2 million shares. The amendment was subsequently approved by the Company's stockholders on May 20, 2021. As of December 31, 2023 and December 31, 2022, 3,123,563 and 3,712,123 shares of the Company’s common stock, respectively, remained available for future issuance under the 2015 Plan, as amended.

Stock-based compensation cost amounted to $12.0 million, $11.5 million and $12.5 million for 2023, 2022 and 2021, respectively. During 2023, 2022 and 2021 there was a $2.4 million, $2.4 million and $1.2 million tax benefit recognized in income related to stock-based compensation.

Restricted Stock and Restricted Stock Units

Restricted stock and restricted stock unit awards are valued at the fair value of the shares on the date of grant. Generally, granted shares and units vest over a two to four year graded vesting period. Each restricted stock unit represents the right to receive one share of common stock upon vesting of such restricted stock unit. Vesting of restricted stock units is based on time-based service conditions. In order to vest, the participant must still be employed by the Company, with certain contractual exclusions, at each vesting event. Generally, within 30 days after vesting, the shares underlying the award will be issued to the participant. In the event a successor corporation in a change in control situation fails to assume or substitute for the restricted stock units, the restricted stock units will automatically vest in full as of immediately prior to the consummation of such change in control. In the event of death or permanent disability of a participant, the restricted stock units will automatically vest in full. Compensation expense is recognized on a straight-line basis over the requisite service period.

A summary of the status of the Company’s restricted stock shares (restricted stock awards and restricted stock unit awards) as of December 31, 2023 and changes during the year ended December 31, 2023 is presented below:

	Number of Shares	Weighted-Average Grant Date Fair Value ($)

Forfeited	(46,424)	21.04
Outstanding at December 31, 2023	705,888	20.93

There were 500,648 and 404,062 restricted stock shares granted during the years ended December 31, 2023 and December 31, 2022, respectively. As of December 31, 2023 and December 31, 2022, there was $8.4 million and $8.6 million, respectively, of total unrecognized compensation cost related to nonvested restricted stock to be recognized over 1.8 years and 1.7 years, respectively.

The weighted-average fair value of restricted stock granted during the years ended December 31, 2023, 2022 and 2021 was $19.58, $23.48 and $25.17, respectively. The total fair value of restricted stock shares vested during the years ended December 31, 2023, 2022 and 2021 was $7.2 million, $7.5 million and $4.6 million, respectively.

Performance and Market Share Awards

The Company grants certain executives performance and market stock units that vest based on either market, performance or market and performance conditions as part of a long-term incentive plan. The number of shares of common stock underlying each award is determined at the end of the performance period. In order to vest, the executive must still be employed by the Company, with certain contractual exclusions, at the end of the performance period.

Stock-based compensation cost related to these awards amounted to $3.0 million, $1.5 million and $3.5 million for 2023, 2022 and 2021, respectively. As of December 31, 2023 and 2022, there was $3.9 million and $3.0 million, respectively, of total unrecognized compensation cost related to nonvested performance and market share awards expected to be recognized over 1.8 years and 1.6 years, respectively.

Debt and Other Obligations

Long-term debt

    As of December 31, 2023, the Company had outstanding public and non-public debt instruments.

Revolving credit facility due in 2025

As of both December 31, 2023 and December 31, 2022, the Company had $300.0 million undrawn and available under its revolving credit facility. Any amounts drawn on this facility are included in long-term debt and finance leases, less current maturities, on the Company's consolidated balance sheets. During the fourth quarter 2023, the Company amended the agreement to extend the final maturity of the facility to September 30, 2025 and adjust other terms.

The Company may pledge the following types of assets as collateral to secure its obligations under the revolving credit facility: (i) certain take-off and landing rights of the Company at LaGuardia Airport, (ii) certain eligible aircraft spare parts and ground support equipment, (iii) aircraft, spare engines and flight simulators, (iv) real property assets and (v) cash and cash equivalents. The revolving credit facility bears variable interest based on SOFR, plus a 2.00% margin per annum, or another rate, at the Company's election, based on certain market interest rates, plus a 1.00% margin per annum, in each case with a floor of 0%.

The 2025 revolving credit facility requires the Company to maintain (i) so long as any loans or letters of credit are outstanding under the 2025 revolving credit facility, unrestricted cash, cash equivalents, short-term investment securities and unused commitments available under all revolving credit facilities (including the 2025 revolving credit facility) aggregating not less than $450.0 million, of which no more than $300.0 million may be derived from unused commitments under the 2025 revolving credit facility, (ii) a minimum ratio of the borrowing base of the collateral described above (determined as the sum of a specified percentage of the appraised value of each type of such collateral) to outstanding obligations under the 2025 revolving credit facility of not less than 1.0 to 1.0 (if the Company does not meet the minimum collateral coverage ratio, it must either provide additional collateral to secure its obligations under the 2025 revolving credit facility or repay the loans under the 2025 revolving credit facility by an amount necessary to maintain compliance with the collateral coverage ratio), and (iii) the pledged take-off and landing rights of the Company at LaGuardia Airport and a specified number of spare engines in the collateral described above so long as any loans or letters of credit are outstanding under the 2025 revolving credit facility.

Convertible senior notes due 2025

On May 12, 2020, the Company completed the public offering of $175.0 million aggregate principal amount of 4.75% convertible senior notes due 2025 ("convertible notes due 2025").

Noteholders may convert their notes at their option only in the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on June 30, 2020 (and only during such calendar quarter), if the last reported sale price per share of the Company’s common stock exceeds 130% of the conversion price for each of at least 20 trading days (whether or not consecutive) during the 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter; (2) during the five consecutive business days immediately after any five consecutive trading day period (such five consecutive trading day period, the “measurement period”) in which the trading price per $1,000 principal amount of notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price per share of the Company’s common stock on such trading day and the conversion rate on such trading day; (3) upon the occurrence of certain corporate events or distributions on the Company’s common stock; and (4) at any time from, and including, February 18, 2025 until the close of business on the second scheduled trading day immediately before the maturity date. As of December 31, 2023, the notes may be converted by noteholders through March 31, 2024.

Based on the terms of the indenture, upon conversion, the Company will pay or deliver, as the case may be, cash, shares of the Company’s common stock or a combination of cash and shares of common stock, at the Company’s election. However, based on the terms of Merger Agreement with JetBlue, upon conversion of any convertible notes due 2025 through the closing or termination of the Merger Agreement with JetBlue, the conversion value, including the principal amount, will be paid all in shares of the Company's common stock. The initial conversion rate was 78.4314 shares of voting common stock per $1,000 principal amount of convertible notes (equivalent to an initial conversion price of approximately $12.75 per share of common stock). The conversion rate will be subject to adjustment in some events but will not be adjusted for any accrued and unpaid interest. Due to the payment of the Approval Prepayment and Additional Prepayment Amounts paid by JetBlue to the Company's stockholders, in accordance with the terms of the indenture, the Company has announced related adjustments to the conversion rate of its convertible senior notes due 2025. As of December 31, 2023, the conversion rate was 94.9262 shares of voting common stock per $1,000 principal amount of convertible notes (equivalent to a conversion price of approximately $10.53 per share of common stock). Refer to Note 3, Current Developments for additional information on the Approval Prepayment and Additional Prepayment Amounts.

During the first quarter of 2023, $0.3 million of the Company's convertible notes due 2025 were converted to 27,204 shares of the Company's voting common stock. As of December 31, 2023, the Company had recorded $0.3 million, net of issuance costs and common stock, in additional paid-in-capital on its consolidated balance sheets related to the conversion of these notes. Since the notes are currently convertible in accordance with the terms of the indenture governing such notes, the Company had $25.1 million recorded within current maturities of long-term debt and finance leases on its consolidated balance sheets as of December 31, 2023 related to its convertible notes due 2025. As of December 31, 2023, the if-converted value exceeds the principal amount of the convertible notes due 2025 by $14.2 million using the average stock price for the twelve months ended December 31, 2023.

Convertible senior notes due 2026

On April 30, 2021, the Company completed the public offering of $500.0 million aggregate principal amount of 1.00% convertible senior notes due 2026 ("convertible notes due 2026").

Noteholders may convert their notes at their option only in the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on June 30, 2021 (and only during such calendar quarter), if the last reported sale price per share of the Company’s common stock exceeds 130% of the conversion price for each of at least 20 trading days (whether or not consecutive) during the 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter; (2) during the five consecutive business days immediately after any five consecutive trading day period (such five consecutive trading day period, the “measurement period”) in which the trading price per $1,000 principal amount of notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price per share of the Company’s common stock on such trading day and the conversion rate on such trading day; (3) upon the occurrence of certain corporate events or distributions on the Company’s common stock; (4) if the Company calls such notes for redemption; and (5) at any time from, and including, February 17, 2026 until the close of business on the second scheduled trading day immediately before the maturity date. As of December 31, 2023, the notes did not qualify for conversion by noteholders through March 31, 2024.

Based on the terms of the indenture, the Company will have the right to elect to settle conversions in cash, shares of the Company's common stock or a combination of cash and shares of common stock. Upon conversion of any notes, the Company will pay the conversion value in cash up to at least the principal amount of the notes being converted. However, based on the terms of the Merger Agreement with JetBlue, upon conversion of any convertible notes due 2026 through the closing or termination of the Merger Agreement with JetBlue, the conversion value, including the principal amount, will be paid all in cash. The conversion value will be determined over an observation period consisting of 40 trading days. The initial conversion rate

was 20.3791 shares of voting common stock per $1,000 principal amount of convertible notes (equivalent to an initial conversion price of approximately $49.07 per share of common stock). The conversion rate will be subject to adjustment in some events but will not be adjusted for any accrued and unpaid interest. Due to the payment of the Approval Prepayment and Additional Prepayment Amounts paid by JetBlue to the Company's stockholders, in accordance with the terms of the indenture, the Company has announced related adjustments to the conversion rate of its convertible senior notes due 2026. As of December 31, 2023, the conversion rate was 24.6649 shares of voting common stock per $1,000 principal amount of convertible notes (equivalent to a conversion price of approximately $40.54 per share of common stock). Refer to Note 3, Current Developments for additional information on the Approval Prepayment and Additional Prepayment Amounts.

The Merger Agreement with JetBlue includes settlement terms for any conversion of the convertible notes due 2026, as described above, that cause the conversion option, which is an embedded derivative, not to qualify for the derivative accounting scope exception provided under ASC 815. As such, the Company bifurcated the fair value of the conversion option of the convertible senior notes due 2026 as a derivative liability with subsequent changes in fair value recorded in earnings. The Company recorded the fair value of the embedded derivative of $49.5 million as a derivative liability within deferred gains and other long-term liabilities and a debt discount within long-term debt and finance leases, less current maturities on its consolidated balance sheets. The debt discount will continue to be amortized through interest expense, using the effective interest rate method, over the remaining life of the instrument.

Since the notes are currently not convertible in accordance with the terms of the indenture governing such notes, the Company had $472.6 million, net of the related unamortized debt discount of $27.4 million, recorded within long-term debt and finance leases, less current maturities on the Company's consolidated balance sheets as of December 31, 2023 related to its convertible notes due 2026. For additional information, refer to Note 18, Fair Value Measurements.

Adoption of ASU No. 2020-06

In August 2020, the FASB issued ASU No. 2020-06, "Accounting for Convertible Instruments and Contracts in an Entity's Own Equity." This standard simplifies and adds disclosure requirements for the accounting and measurement of convertible instruments. It eliminates the treasury stock method for convertible instruments and requires application of the “if-converted” method for certain agreements when computing earnings per share. In addition, the standard eliminates the beneficial conversion and cash conversion accounting models that require separate accounting for embedded conversion features and the recognition of a debt discount and related amortization to interest expense of those embedded features.

The Company elected to early adopt this standard effective January 1, 2021 using the modified retrospective approach transition method. Therefore, the consolidated financial statements for the years ended December 31, 2023, 2022 and 2021 are presented under the new standard.

In connection with the adoption of this standard, the Company recognized a cumulative effect adjustment, net of tax, of $6.1 million to retained earnings on the Company's consolidated balance sheet as of January 1, 2021. This adjustment was primarily driven by the derecognition of interest expense related to the accretion of the debt discount associated with the embedded conversion option recorded in the prior period as required under the legacy guidance. In addition, the Company reclassified $75.6 million, less related tax of $17.1 million and issuance costs of $2.9 million, from additional paid-in-capital ("APIC") to long-term debt and finance leases on the Company's consolidated balance sheet as of January 1, 2021. The reclassification was recorded in order to combine the two legacy units of account into a single instrument classified as a liability since bifurcation of the instrument into two units of account is no longer required under this standard.

Long-term debt is comprised of the following:

Leases [Abstract]

Leases

Leases

The Company leases aircraft, engines, airport terminals, maintenance and training facilities, aircraft hangars, commercial real estate and office and computer equipment, among other items. Certain of these leases include provisions for variable lease payments which are based on several factors, including, but not limited to, relative leases square footage, enplaned passengers, and airports' annual operating budgets. Due to the variable nature of the rates, these leases are not recorded on the Company's consolidated balance sheets as a right-of-use asset and lease liability. Lease terms are generally 4 to 18 years for aircraft and up to 99 years for other leased equipment and property.

As of December 31, 2023, the Company had a fleet consisting of 205 A320 family aircraft. As of December 31, 2023, the Company had 117 aircraft financed under operating leases with lease term expirations between 2025 and 2041. In addition, the Company owned 73 aircraft of which, as of December 31, 2023, 17 were unencumbered. The Company also had 15 aircraft that would have been deemed finance leases resulting in failed sale-leaseback transactions. The related finance obligation is recorded within long-term debt in the Company's consolidated balance sheets. Refer to Note 13, Debt and Other Obligations for additional information. The related asset is recorded within flight equipment in the Company's consolidated balance sheets. As of December 31, 2023, the Company also had 6 spare engines financed under operating leases with lease term expiration dates ranging from 2024 to 2033 and owned 28, of which, as of December 31, 2023, 4 were unencumbered and 24 were pledged as collateral under the Company's revolving credit facility maturing in 2025.

Total rent expense for the years ended 2023, 2022 and 2021 was $673.2 million, $537.9 million and $449.4 million, respectively. Total rental expense for aircraft and engine operating leases for the years ended December 31, 2023, 2022 and 2021 was $381.2 million, $282.4 million and $246.6 million, respectively.

Under the terms of the lease agreements, the Company will continue to operate and maintain the aircraft. Payments under the majority of the lease agreements are fixed for the term of the lease. The lease agreements contain standard termination events, including termination upon a breach of the Company's obligations to make rental payments and upon any other material breach of the Company's obligations under the leases, and standard maintenance and return condition provisions. These return provisions are evaluated at inception of the lease and throughout the lease terms and are accounted for as either fixed or variable lease payments (depending on the nature of the lease return condition) when it is probable that such amounts will be incurred. When determining probability and estimated cost of lease return obligations, there are various other factors that need to be considered such as the contractual terms of the lease, the ability to swap engines or other aircraft components, current condition of the aircraft, the age of the aircraft at lease expiration, utilization of engines and other components, the extent of repairs needed at return, return locations, current configuration of the aircraft and cost of repairs and materials at the time of return. Management assesses the factors listed above and the need to accrue lease return costs throughout the lease as facts and circumstances warrant an assessment. The Company expects lease return costs will increase as individual aircraft lease agreements approach their respective termination dates and the Company begins to accrue the estimated cost of return conditions for the corresponding aircraft. Upon a termination of the lease due to a breach by the Company, the Company would be liable for standard contractual damages, possibly including damages suffered by the lessor in connection with remarketing the aircraft or while the aircraft is not leased to another party.

Aircraft rent expense consists of monthly lease rents for aircraft and spare engines under the terms of the Company's aircraft and spare engine lease agreements recognized on a straight-line basis. Supplemental rent, recorded within aircraft rent expense, is primarily made up of probable and estimable return condition obligations, lease return costs adjustments for aircraft and engines purchased off lease or lease extensions or amendments. The Company expensed $14.0 million, $16.5 million and $31.7 million of supplemental rent recorded within aircraft rent during 2023, 2022 and 2021, respectively.

During the twelve months ended December 31, 2023, the Company took delivery of 13 new aircraft under direct operating leases, 10 new aircraft under sale-leaseback transactions and 4 engines purchased with cash.

Under Topic 842, gains and losses on sale-leaseback transactions, subject to adjustment for off-market terms, are recognized immediately and recorded within gain/loss on disposal of assets on the Company's consolidated statements of operations. Refer to Note 5, Loss on Disposal of Assets for additional information on the losses recorded related to the sale-leaseback transactions entered into during the twelve months ended December 31, 2023, 2022 and 2021.

As of December 31, 2023, the Company's finance lease obligations relate to the lease of computer equipment used by the Company's flight crew and office equipment. Payments under these finance lease agreements are fixed for terms ranging from 4 to 5 years. Finance lease assets are recorded within property and equipment and the related liabilities are recorded within long-term debt and finance leases in the Company's consolidated balance sheets.

During the fourth quarter of 2019, the Company purchased an 8.5-acre parcel of land for $41.0 million and entered into a 99-year lease agreement for the lease of a 2.6-acre parcel of land, in Dania Beach, Florida, where the Company is building its new headquarters campus and a 200-unit residential building. During the first quarter of 2022, the Company began building its new headquarters campus and its 200-unit residential building with an expected completion during the first quarter of 2024. As of December 31, 2023, the 8.5-acre parcel of land and $184.6 million in related construction costs were capitalized within ground property and equipment on the Company's consolidated balance sheets. The 99-year lease was determined to be an operating lease and is recorded within operating lease right-of-use asset and operating lease liability on the Company's consolidated balance sheets. Operating lease commitments related to this lease are included in the table below within property facility leases.

The following table provides details of the Company's future minimum lease payments under finance lease liabilities and operating lease liabilities recorded on the Company's consolidated balance sheets as of December 31, 2023. The table does not include commitments that are contingent on events or other factors that are currently uncertain and unknown.

During the fourth quarter of 2019, the Company purchased an 8.5-acre parcel of land for $41.0 million and entered into a 99-year lease agreement for the lease of a 2.6-acre parcel of land, in Dania Beach, Florida, where the Company is building its new headquarters campus and a 200-unit residential building. During the first quarter of 2022, the Company began building its new headquarters campus and its 200-unit residential building with an expected completion during the first quarter of 2024. As of December 31, 2023, the 8.5-acre parcel of land and $184.6 million in related construction costs were capitalized within ground property and equipment on the Company's consolidated balance sheets. The 99-year lease was determined to be an operating lease and is recorded within operating lease right-of-use asset and operating lease liability on the Company's consolidated balance sheets. Operating lease commitments related to this lease are included in the table below within property facility leases.

The following table provides details of the Company's future minimum lease payments under finance lease liabilities and operating lease liabilities recorded on the Company's consolidated balance sheets as of December 31, 2023. The table does not include commitments that are contingent on events or other factors that are currently uncertain and unknown.

The Company accounts for income taxes using the asset and liability method. Deferred taxes are recorded based on differences between the consolidated financial statement basis and tax basis of assets and liabilities and available tax loss and credit carryforwards. At December 31, 2023 and 2022, the significant components of the Company's deferred taxes consisted of the following:

	December 31,
	2023		2022
	(in thousands)
Deferred tax assets:
Income tax credits	$	4,298	$	4,306
Net operating losses	328,977		340,023

Deferred tax liabilities	1,499,915		1,295,881
Net deferred tax assets (liabilities)	$	(107,761)	$	(226,843)

In assessing the realizability of the deferred tax assets, management considered whether it is more likely than not that some or all of the deferred tax assets would be realized. In evaluating the Company’s ability to utilize its deferred tax assets, it considered all available evidence, both positive and negative, in determining future taxable income on a jurisdiction by jurisdiction basis. As of December 31, 2023 and 2022, the Company had a valuation allowance of $17.7 million and $10.9 million, respectively, against certain deferred tax assets related to equity compensation for executives due to changes in tax law resulting from the Tax Cuts and Jobs Act ("TCJA"), state net operating loss carryforwards and foreign tax credits.

As of December 31, 2023, the Company had $2.8 million of foreign tax credits, $1.4 million of general business tax credits, $1.4 billion of federal net operating loss and $643.5 million of state net operating loss available, that may be applied against future tax liabilities. The foreign tax credits will begin to expire in 2025, the state net operating losses will begin to expire in 2027, the general business credits will begin to expire in 2038 and there is no expiration of federal net operating losses.

For tax years ended December 31, 2023, 2022 and 2021, the Company did not recognize any liabilities for uncertain tax positions nor any interest and penalties on unrecognized tax benefits.

For tax years 2023, 2022 and 2021, all income for the Company is subject to domestic income taxes.

The Company files its tax returns as prescribed by the tax laws of the jurisdictions in which it operates. The Company's federal income tax returns for 2020 through 2022 tax years are still subject to examination in the United States Various state and foreign jurisdiction tax years also remain open to examination. The Company believes that any potential assessment would be immaterial to its consolidated financial statements.

Commitments and Contingencies

Commitments and Contingencies

Aircraft-Related Commitments and Financing Arrangements

The Company’s contractual purchase commitments consist primarily of aircraft and engine acquisitions through manufacturers and aircraft leasing companies. As of December 31, 2023, the Company's firm aircraft orders consisted of 99 A320 family aircraft with Airbus, including A320neos and A321neos, with deliveries expected through 2029. On July 31, 2023, the Company entered into Amendment No. 6 (the “Amendment”) to the A320 NEO Family Purchase Agreement, dated as of December 20, 2019 (the “Airbus Purchase Agreement”) with Airbus S.A.S. (“Airbus”). The Amendment converts the remaining A319neo aircraft to be delivered under the Airbus Purchase Agreement to A321neo aircraft. The Amendment also (i) defers certain A320neo aircraft deliveries from 2024 to 2025 and later years, (ii) extends delivery dates for certain A320neo and A321neo aircraft deliveries from 2025-2027 to 2025-2029 and (iii) adjusts the timing of option aircraft delivery dates from 2026-2028 to 2027-2029. In addition, the Amendment creates a more equal distribution of aircraft deliveries and option rights across the delivery periods. As of December 31, 2023, the Company had secured financing for 18 aircraft, scheduled for delivery from Airbus through 2025, which will be financed through sale-leaseback transactions. The Company did not have financing commitments in place for the remaining 81 Airbus aircraft currently on firm order, which are scheduled for delivery through 2029. However, the Company has signed a financing letter of agreement with Airbus which provides backstop financing for a majority of the aircraft included in the A320 NEO Family Purchase Agreement. The agreement provides a standby credit facility in the form of senior secured mortgage debt financing. The contractual purchase amounts for these aircraft are included within the purchase commitments below.

During the third quarter of 2021, the Company entered into an Engine Purchase Support Agreement which requires the Company to purchase a certain number of spare engines in order to maintain a contractual ratio of spare engines to aircraft in the fleet. As of December 31, 2023, the Company is committed to purchase 19 PW1100G-JM spare engines, with deliveries through 2029.

As of December 31, 2023, committed expenditures for these aircraft and spare engines, including estimated amounts for contractual price escalations and pre-delivery payments, are expected to be $507.6 million in 2024, $1,018.6 million in 2025, $1,034.3 million in 2026, $1,100.0 million in 2027, $1,035.2 million in 2028, and $923.8 million in 2029 and beyond.

During the third quarter of 2019, the United States announced its decision to levy tariffs on certain imports from the European Union, including commercial aircraft and related parts. These tariffs include aircraft and other parts that the Company is already contractually obligated to purchase including those reflected above. In June 2021, the United States Trade Representative announced that the United States and European Union had agreed to suspend reciprocal tariffs on large civilian aircraft for five years, pending discussions to resolve their trade dispute. For further discussion on this topic, please refer to "Risk Factors - Risks Related to Our Business - Any tariffs imposed on commercial aircraft and related parts imported from outside the United States may have a material adverse effect on our fleet, business, financial condition and our results of operations."

In addition to the aircraft purchase agreement, as of December 31, 2023, the Company had secured financing for 22 aircraft to be leased directly from third-party lessors, scheduled for delivery through 2025. As of December 31, 2023, aircraft rent commitments for future aircraft deliveries to be financed under direct leases from third-party lessors and sale-leaseback transactions are expected to be approximately $72.4 million in 2024, $167.8 million in 2025, $183.3 million in 2026, $183.3 million in 2027, $183.3 million in 2028, and $1,409.3 million in 2029 and beyond.

Interest commitments related to the secured debt financing of 71 aircraft as of December 31, 2023 are $80.2 million in 2024, $73.6 million in 2025, $67.3 million in 2026, $60.2 million in 2027, $51.7 million in 2028, and $204.5 million in 2029 and beyond. As of December 31, 2023, interest commitments related to the Company's 8.00% senior secured notes, convertible debt financing, unsecured term loans and revolving credit facility are $96.7 million in 2024, $89.4 million in 2025, $5.9 million in 2026, $3.4 million in 2027, $3.4 million in 2028, and $7.1 million in 2029 and beyond. For principal commitments related to the Company's outstanding debt obligations, refer to Note 13, Debt and Other Obligations.

The Company is contractually obligated to pay the following minimum guaranteed payments for its reservation system, construction commitments related to its new headquarters campus and residential building and other miscellaneous subscriptions and services as of December 31, 2023: $65.0 million in 2024, $27.5 million in 2025, $18.1 million in 2026, $18.0 million in 2027, $1.9 million in 2028, and none in 2029 and beyond. During the first quarter of 2018, the Company entered into a contract renewal with its reservation system provider which expires in 2028.

Litigation

The Company is subject to commercial litigation claims and to administrative and regulatory proceedings and reviews that may be asserted or maintained from time to time. The Company believes the ultimate outcome of such lawsuits, proceedings and reviews will not, individually or in the aggregate, have a material adverse effect on its financial position, liquidity or results of operations. In making a determination regarding accruals, using available information, the Company evaluates the likelihood of an unfavorable outcome in legal or regulatory proceedings and assessments to which the Company is a party and records a loss contingency when it is probable a liability has been incurred and the amount of the loss can be reasonably estimated. These subjective determinations are based on the status of such legal or regulatory proceedings, the merits of the Company's defenses, and consultation with legal counsel. Actual outcomes of these legal and regulatory proceedings may materially differ from the Company's current estimates. It is possible that resolution of one or more of the legal matters currently pending or threatened could result in losses material to the Company's consolidated results of operations, liquidity, or financial condition.

In 2017, the Company was sued in the Eastern District of New York ("EDNY") in a purported class action, Cox, et al. v. Spirit Airlines, Inc., alleging state-law claims of breach of contract, unjust enrichment and fraud relating to the Company's practice of charging fees for ancillary products and services. The original action was dismissed by the EDNY; however, following the plaintiff's appeal to the Second Circuit, the case was remanded to the EDNY for further review on the breach of contract claim. A hearing on the Company's Motion for Summary Judgment and plaintiff's Motion for Class Certification was held on December 10, 2021. The EDNY granted the plaintiff's class certification motion and denied Spirit’s summary judgment motion on March 29, 2022. The Company subsequently filed a motion for reconsideration on April 26, 2022, and an oral argument was held on May 19, 2022. The EDNY denied Spirit’s motion for reconsideration on February 14, 2023. On April 3, 2023, Spirit moved to compel arbitration of and/or dismiss certain class members’ claims for lack of personal jurisdiction. Trial was set to begin on January 16, 2024. In June 2023, the Company reached a tentative settlement in mediation for a maximum amount of $8.3 million. The EDNY issued a preliminary approval order on September 21, 2023, and the final approval hearing was held on December 11, 2023. The total amount paid depends on a number of factors, including participation of class members and any conditions on the settlement approved by the EDNY. Currently, the Company's best estimate of the probable loss associated with the settlement is $6.0 million, and the Company has recorded this amount in other operating expenses within its consolidated statements of operations.

On February 27, 2023, ALPA filed a grievance against the Company claiming that it violated the collective bargaining agreement (“CBA”) by excluding its pilots from the Company's retention award programs granted as part of the Former Frontier Merger Agreement and the Merger Agreement with JetBlue. On September 8, 2023, the Company filed a motion to dismiss the grievance, as it does not believe that ALPA filed the grievance within the timeline set forth in the CBA. As of December 31, 2023, the potential outcomes of this claim cannot be determined and an estimate of the reasonably possible loss or range of loss cannot be made.

Following an audit by the Internal Revenue Service ("IRS") related to the collection of federal excise taxes on optional passenger seat selection charges covering the period of the second quarter 2018 through the fourth quarter 2020, on March 31, 2022, the Company was assessed $34.9 million. On July 19, 2022, the assessment was reduced to $27.5 million. The Company believes a loss in this matter is not probable and has not recognized a loss contingency.

Employees

The Company has six union-represented employee groups that together represent approximately 85% of all employees at December 31, 2023. The table below sets forth the Company's employee groups and status of the collective bargaining agreements as of December 31, 2023. 

Employee Groups	Representative	Amendable Date (1)	Percentage of Workforce
Pilots	Air Line Pilots Association, International (ALPA)	January 2025	27%
Flight Attendants	Association of Flight Attendants (AFA-CWA)	January 2026	47%
Dispatchers	Professional Airline Flight Control Association (PAFCA)	October 2023	1%
Ramp Service Agents	International Association of Machinists and Aerospace Workers (IAMAW)	November 2026	3%
Passenger Service Agents	Transport Workers Union of America (TWU)	February 2027	2%
Aircraft Maintenance Technicians	Aircraft Mechanics Fraternal Association (AMFA) (2)	N/A (2)	5%

(1) Subject to standard early opener provisions.

(2) Collective bargaining agreement is currently under negotiation.

During the fourth quarter of 2022, the Company reached an agreement with ALPA for a new two-year agreement, which was ratified by ALPA members on January 10, 2023. The ratified agreement includes increased pay rates and other enhanced benefits.

In February 2023, the Company and AFA-CWA reached an agreement with the Company's flight attendants which was ratified by the flight attendants on April 13, 2023 and becomes amendable in January 2026. The ratified agreement includes increased pay rates and other enhanced benefits.

In August 2022, the Company's aircraft maintenance technicians ("AMTs") voted to be represented by the Aircraft Mechanics Fraternal Association ("AMFA") as their collective bargaining agent. As of December 31, 2023, the Company employed approximately 700 AMTs. In November 2022, AMFA notified the Company of its intent to negotiate a CBA and began negotiations. In October 2023, AMFA filed for mediation with the National Mediation Board (“NMB”). The Company is currently waiting for mediation dates from the NMB to continue negotiating with AMFA.

In May 2023, PAFCA provided notice to the Company that it intends to amend its Collective Bargaining Agreement with its dispatchers. The parties began negotiating changes to the CBA on July 12, 2023. As of December 31, 2023, the Company continued to negotiate with PAFCA.

The Company is self-insured for health care claims, subject to a stop-loss policy, for eligible participating employees and qualified dependent medical claims, subject to deductibles and limitations. The Company’s liabilities for claims incurred but not reported are determined based on an estimate of the ultimate aggregate liability for claims incurred. The estimate is calculated from actual claim rates and adjusted periodically as necessary. The Company has accrued $9.1 million and $11.0 million, for health care claims as of December 31, 2023, and 2022, respectively, recorded within other current liabilities on the Company's consolidated balance sheet.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

Under ASC 820, Fair Value Measurements and Disclosures, disclosures relating to how fair value is determined for assets and liabilities are required, and a hierarchy for which these assets and liabilities must be grouped is established, based on significant levels of inputs, as follows:

Level 1—Quoted prices in active markets for identical assets or liabilities.

Level 2—Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company utilizes several valuation techniques in order to assess the fair value of the Company’s financial assets and liabilities.

Long-term Debt

    The estimated fair value of the Company's secured notes, term loan debt agreements and revolving credit facilities has been determined to be Level 3 as certain inputs used to determine the fair value of these agreements are unobservable. The Company utilizes a discounted cash flow method to estimate the fair value of the Level 3 long-term debt. The estimated fair value of the Company's publicly and non-publicly held EETC debt agreements and the Company's convertible notes has been determined to be Level 2 as the Company utilizes quoted market prices in markets with low trading volumes to estimate the fair value of its Level 2 long-term debt.

    The carrying amounts and estimated fair values of the Company's long-term debt at December 31, 2023 and December 31, 2022, were as follows:

	As of December 31,
	2023				2022

Cash and Cash Equivalents

Cash and cash equivalents at December 31, 2023 and December 31, 2022 are comprised of liquid money market funds and cash and are categorized as Level 1 instruments. The Company maintains cash with various high-quality financial institutions.

Restricted Cash

Restricted cash is comprised of cash held in account subject to account control agreements or otherwise pledged as collateral against the Company's letters of credit and is categorized as a Level 1 instrument. As of December 31, 2023, the Company had a $85.0 million standby letter of credit secured by $75.0 million of restricted cash, of which $55.9 million were issued letters of credit. In addition, the Company had $44.4 million of restricted cash held in accounts subject to control agreements to be used for the payment of interest and fees on the Company's 8.00% senior secured notes. For additional information on the Company's 8.00% senior secured notes, refer to Note 13, Debt and Other Obligations.

Short-term Investment Securities

Short-term investment securities at December 31, 2023 and December 31, 2022 are classified as available-for-sale and generally consist of U.S. Treasury and U.S. government agency securities with contractual maturities of twelve months or less.

The Company's short-term investment securities are categorized as Level 1 instruments, as the Company uses quoted market prices in active markets when determining the fair value of these securities. For additional information, refer to Note 8, Short-term Investment Securities.

Derivative Liability

The Merger Agreement with JetBlue modified the settlement terms for any conversions of the convertible notes due 2026 (as defined below) that caused the conversion option, which is an embedded derivative, not to qualify for the derivative accounting scope exception provided under ASC 815. As such, the Company bifurcated the fair value of the conversion option of the convertible notes due 2026 as a derivative liability with subsequent changes in fair value recorded in earnings.

The Company records the fair value of the embedded derivative as a derivative liability within deferred gains and other long-term liabilities on its consolidated balance sheets. The fair value of the derivative liability was estimated as the difference in value of the traded price of the convertible notes, including the conversion option and the value of the convertible notes in the absence of the conversion option (the debt component). The value of the debt component was estimated using a discounted cash flow analysis with a yield calibrated to the traded price of the convertible notes. The change in fair value of the derivative liability is recorded within interest expense on the Company's consolidated statements of operations and is included in other liabilities within operating activities in the Company's consolidated statements of cash flows. During the twelve months ended December 31, 2023 and 2022, the Company recorded $18.1 million and $20.3 million, respectively, in a favorable mark to market adjustment, related to the change in fair value of the derivative liability. The fair value of the derivative liability has been determined to be Level 2 as observable inputs were used to determine the fair value of derivative liability. For additional information, refer to Note 13, Debt and Other Obligations.

Assets and liabilities measured at gross fair value on a recurring basis are summarized below:

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2023

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The accompanying consolidated financial statements include the accounts of Spirit Airlines, Inc. ("Spirit") and its consolidated subsidiaries (the "Company"). Spirit is an ultra low-cost, low-fare airline that provides affordable travel opportunities principally throughout the domestic United States, the Caribbean and Latin America and is headquartered in Miramar, Florida. Spirit manages operations on a system-wide basis due to the interdependence of its route structure in the various markets served. As only one service is offered (i.e., air transportation), management has concluded there is only one reportable segment.

Use of Estimates

Use of Estimates

The preparation of financial statements in accordance with generally accepted accounting principles in the United States of America requires the Company's management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The Company's estimates and assumptions are based on historical experience and changes in the business environment. However, actual results may differ from estimates under different conditions, sometimes materially.

Cash and Cash Equivalents, Restricted Cash

Cash and Cash Equivalents

The Company considers all highly liquid investments with maturities of less than three months at the date of acquisition to be cash equivalents. Investments included in this category primarily consist of cash and money market funds. Cash and cash equivalents are stated at cost, which approximates fair value.

Restricted Cash

The Company's restricted cash is comprised of cash held in account subject to account control agreements to be used for the payment of interest and fees on the Company's 8.00% senior secured notes and cash pledged as collateral against the Company's secured letters of credit.

Short-term Investment Securities

Short-term Investment Securities

The Company's short-term investment securities are classified as available-for-sale and generally consist of U.S. Treasury and U.S. government agency securities with contractual maturities of twelve months or less. These securities are stated at fair value within current assets on the Company's consolidated balance sheet. For all short-term investments, at each reset period or upon reinvestment, the Company accounts for the transaction as proceeds from the maturity of short-term investment securities for the security relinquished, and purchase of short-term investment securities for the security purchased, in the Company's consolidated statements of cash flows. Realized gains and losses on sales of investments, if any, are reflected in non-operating other (income) expense in the consolidated statements of operations. Unrealized gains and losses on investment securities are reflected as a component of accumulated other comprehensive income.

Accounts Receivable

Accounts Receivable

Accounts receivable primarily consist of amounts due from credit card processors associated with the sales of tickets, amounts due from the Internal Revenue Service related to federal excise fuel tax and amounts expected to be received related to the CARES Employee Retention credit. The Company records an allowance for amounts not expected to be collected. The Company estimates the allowance based on historical write-offs and aging trends as well as an estimate of the expected lifetime credit losses.

Income Tax Receivable

Income Tax Receivable

Income tax receivable consists of amounts due from tax authorities for recovery of income taxes paid in prior periods.

Income Taxes

The Company accounts for income taxes using the asset and liability method. The Company records a valuation allowance to reduce the deferred tax assets reported if, based on the weight of the evidence, it is more likely than not that some

portion or all of the deferred tax assets will be not realized.

Property and Equipment

Property and Equipment

Property and equipment is stated at cost, less accumulated depreciation and amortization. Depreciation of operating property and equipment is computed using the straight-line method applied to each unit of property. Residual values for new aircraft, new engines, major spare rotable parts, avionics and assemblies are generally estimated to be 10%. Property under

finance leases and related obligations are initially recorded at an amount equal to the present value of future minimum lease payments computed using the Company's incremental borrowing rate or, when known, the interest rate implicit in the lease. Amortization of property under finance leases is recorded on a straight-line basis over the lease term and is included in depreciation and amortization expense.

The depreciable lives used for the principal depreciable asset classifications are:

	Estimated Useful Life
Aircraft, engines and flight simulators	25
Spare rotables and flight assemblies	7 to 25 years
Other equipment and vehicles	5 to 7 years
Internal use software	3 to 10 years
Finance leases	Lease term or estimated useful life of the asset
Leasehold improvements	Lesser of lease term or estimated useful life of the improvement
Buildings	Lesser of lease term or 30 years

The Company capitalizes certain internal and external costs associated with the acquisition and development of internal-use software for new products, and enhancements to existing products, that have reached the application development stage and meet recoverability tests. Capitalized costs include external direct costs of materials and services utilized in developing or obtaining internal-use software, and labor cost for employees who are directly associated with, and devote time, to internal-use software projects.

The Company accounts for heavy maintenance and major overhaul under the deferral method whereby the cost of heavy maintenance and major overhaul is deferred and amortized until the earlier of the end of the useful life of the related asset, the end of the remaining lease term or the next scheduled heavy maintenance event.

The Company records amortization of capitalized software on a straight-line basis within depreciation and amortization expense in the accompanying consolidated statements of operations.

Operating Lease Right-of-Use Asset and Liabilities

Operating Lease Right-of-Use Asset and Liabilities

Right-of-use assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. Right-of-use assets and lease liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. When available, the Company uses the rate implicit in the lease to discount lease payments to present value. However, the Company's leases generally do not provide a readily determinable implicit rate. Therefore, the Company estimates the incremental borrowing rate to discount lease payments based on information available at lease commencement. The Company uses publicly available data for instruments with similar characteristics when calculating its incremental borrowing rates. The Company has options to extend certain of its operating leases for an additional period of time and options to early terminate several of its

operating leases. The lease term consists of the noncancellable period of the lease, periods covered by options to extend the lease if the Company is reasonably certain to exercise the option, periods covered by an option to terminate the lease if the Company is reasonably certain not to exercise the option and periods covered by an option to extend or not terminate the lease in which the exercise of the option is controlled by the lessor. The Company's lease agreements do not contain any residual value guarantees. The Company elected to not separate non-lease components from the associated lease component for all underlying classes of assets with lease and non-lease components.

The Company elected not to apply the recognition requirements in Topic 842 to short-term leases (i.e., leases of 12 months or less) but instead recognize these lease payments in income on a straight-line basis over the lease term. The Company elected this accounting policy for all classes of underlying assets. In addition, in accordance with Topic 842, variable lease payments are not included in the recognition of a lease liability or right-of-use asset.

Pre-Delivery Deposits On Flight Equipment

Pre-Delivery Deposits on Flight Equipment

The Company is required to make pre-delivery deposit payments ("PDPs") towards the purchase price of each new aircraft and engine prior to the scheduled delivery date. These deposits are initially classified as pre-delivery deposits on flight equipment on the Company's consolidated balance sheets until the aircraft or engine is delivered, at which time the related PDPs are deducted from the final purchase price of the aircraft or engine and are reclassified to flight equipment on the Company's consolidated balance sheets.

In addition, the Company capitalizes the interest that is attributable to the outstanding PDP balances as a percentage of the related debt on which interest is incurred. Capitalized interest represents interest cost incurred during the acquisition period of a long-term asset, and is the amount which theoretically could have been avoided had the Company not paid PDPs for the related aircraft or engines.

Related interest is capitalized and included within pre-delivery deposits on flight equipment through the acquisition period until delivery is taken of the aircraft or engine and the asset is ready for service. Once the aircraft or engine is delivered, the capitalized interest is also reclassified into flight equipment on the Company's consolidated balance sheets along with the related PDPs as they are included in the cost of the aircraft or engine. Capitalized interest for 2023, 2022 and 2021 was primarily related to the interest incurred on long-term debt.

Measurement of Asset Impairments

Measurement of Asset Impairments

The Company records impairment charges on long-lived assets used in operations when events and circumstances indicate that the assets may be impaired, the undiscounted future cash flows estimated to be generated by those assets are less than the carrying amount of those assets, and the net book value of the assets exceeds their estimated fair value. Factors which could be indicators of impairment include but are not limited to (1) a decision to permanently remove flight equipment or other long-lived assets from operations, (2) significant changes in the estimated useful life, (3) significant changes in projected cash flows, (4) permanent and significant declines in related fair values and (5) changes to the regulatory environment. In making these determinations, the Company uses certain assumptions, including, but not limited to: (i) estimated fair value of the assets; and (ii) estimated, undiscounted future cash flows expected to be generated by these assets, which are based on additional assumptions such as asset utilization, length of service the asset will be used in the Company’s operations, and estimated salvage values.

During 2023, the Company did not recognize impairment-related charges. During the fourth quarter of 2022, the Company made the decision to accelerate the retirement of 29 of its A319 aircraft, which were owned and unencumbered, as of December 31, 2022. In January 2023, the Company executed a purchase agreement to sell these aircraft over the next two years. The Company concluded that Management’s plan to early retire and ultimately sell these 29 A319 aircraft is an impairment indicator which required the Company to test the recoverability of the related asset group as of December 31, 2022. No impairment indicators existed and no charges were necessary under applicable accounting standards as of December 31, 2022, for the remaining flight equipment, which together represent one asset group.

The Company concluded that the net book value of this specific asset group of owned A319 aircraft is not recoverable as of December 31, 2022, due to changes to the estimated future cash flows primarily driven by the significant reductions to their remaining operating lives. As a result, during 2022, the Company recognized $333.7 million in impairment-related charges for the amount by which the carrying amount of this asset group, including the related net capitalized maintenance, exceeded its estimated fair value. During 2022, the impairment charges were recorded within special charges (credits) in the Company’s consolidated statement of operations. The fair values of these assets were determined using Level 3 fair value inputs primarily based on the agreed upon sales price for each aircraft, adjusted for estimated utilization in the period of operation from December 31, 2022 to the expected future sales date. For additional information, refer to Note 4, Special Charges and Credits.

Revenues

Passenger Revenues

    Fare revenues. Tickets sold are initially deferred within air traffic liability ("ATL") on the Company's consolidated balance sheet. Passenger fare revenues are recognized at time of departure when transportation is provided. Generally, all tickets sold by the Company are nonrefundable.

Non-fare revenues. Non-fare revenues is primarily comprised of certain ancillary items such as bags, seats and other travel-related fees, which are deemed part of the single performance obligation of providing passenger transportation. These ancillary items are recognized in non-fare revenues within passenger revenues, at the time of departure. In addition, non-fare revenues related to other travel-related programs and services provided are recognized as deemed appropriate.

The following table shows disaggregated operating revenues for the twelve months ended December 31, 2023, 2022 and 2021:

	Twelve Months Ended December 31,
	2023		2022		2021
	(in thousands)
Operating revenues:
Fare	$	2,338,191	$	2,455,817	$	1,422,927
Non-fare	2,929,970		2,533,548		1,752,875
Total passenger revenues	5,268,161		4,989,365		3,175,802
Other	94,388		79,082		54,973
Total operating revenues	$	5,362,549	$	5,068,447	$	3,230,775

Changes and cancellations. An unused ticket expires at the date of scheduled travel, at which time a service charge is assessed, and is recognized as revenue at the date of scheduled travel. However, customers may elect to change or cancel their itinerary prior to the date of departure. For changes, a service charge is recognized at time of departure of newly scheduled travel and is deducted from the face value of the original purchase price of the ticket, and the original ticket becomes invalid. For cancellations, a service charge is assessed and the amount remaining after deducting the service charge is called a credit shell which generally expires 90 days from the date the credit shell is created. Credit shells can be used towards the purchase of a new ticket and the Company’s other service offerings. Both service charge and credit shell amounts are recorded as deferred revenue and amounts expected to expire unused are estimated based on historical experience.

Estimating the amount of credits that will go unused involves some level of subjectivity and judgment. Assumptions used to generate breakage estimates can be impacted by several factors including, but not limited to, changes to the Company's ticketing policies, changes to the Company’s refund, exchange, and credit shell policies, and economic factors. The amount of credit shells issued varies, primarily due to the flight delays and cancellation events throughout the year. The Company generally experiences some variability in the amount of breakage revenue recognized throughout the year and expects some variability in the amount of breakage revenue recorded in future periods, as the estimates of the portion of those funds that will expire unused may differ from historical experience.

Other Revenues

Other revenues primarily consist of the marketing component of the sale of loyalty points to the Company's credit card partner and commissions revenue from the sale of various items such as hotels and rental cars.

Loyalty Program

The Company operates the Free Spirit loyalty program (the "Free Spirit Program"), which attracts members and partners and builds customer loyalty for the Company by offering a variety of awards, benefits and services. Free Spirit Program members earn and accrue points for dollars spent on Spirit for flights and other non-fare services as well as services from non-air partners such as retail merchants, hotels or car rental companies or by making purchases with credit cards issued by partner banks and financial services providers. Points are redeemable by customers in future periods for air travel on Spirit.

    To reflect the point credits earned, the program includes two types of transactions that are considered revenue arrangements with multiple performance obligations: (1) points earned with travel and (2) points sold to its co-branded credit card partner.

    Passenger ticket sales earning points. Passenger ticket sales earning points provide customers with (1) points earned and (2) air transportation. The Company values each performance obligation on a stand-alone basis and allocates the consideration to each performance obligation based on their relative fair value. To value the point credits earned, the Company considers the quantitative value a passenger receives by redeeming points for a ticket rather than paying cash, which is referred to as equivalent ticket value ("ETV").

The Company defers revenue for the points when earned and recognizes loyalty travel awards in passenger revenue as the points are redeemed and services are provided. The Company records the air transportation portion of the passenger ticket sales in air traffic liability and recognizes passenger revenue when transportation is provided or if the ticket goes unused, at the date of scheduled travel.

    Sale of points. Customers may earn points based on their spending with the Company's co-branded credit card company with which the Company has an agreement to sell points. The contract to sell points under this agreement has multiple performance obligations, as discussed below.

The Company's co-branded credit card agreement provides for joint marketing where cardholders earn points for making purchases using co-branded cards. During 2023, the Company extended its agreement with the administrator of the Free Spirit affinity credit card program through December 31, 2028. The Company accounts for this agreement consistently with the accounting method that allocates the consideration received to the individual products and services delivered. The value is allocated based on the relative stand-alone selling prices of those products and services, which generally consists of (i) points to be awarded, (ii) airline benefits, (iii) licensing of brand and access to member lists and (iv) advertising and marketing efforts. The Company determined the estimate of the stand-alone selling prices by considering discounted cash flow analysis using multiple inputs and assumptions, including: (1) the expected number of points awarded and number of points redeemed, (2) the estimated stand-alone selling price of the award travel obligation and airline benefits, (3) licensing of brand access to member lists and (4) the cost of advertising and marketing efforts undertaken by the Company.

The Company defers the amount for award travel obligation as part of loyalty deferred revenue. These amounts that are expected to be redeemed during the following twelve months are recorded within ATL on the consolidated balance sheet and the portion that is not expected to be redeemed during the following twelve months is recorded within long-term liabilities on the consolidated balance sheet. In addition, the Company recognizes loyalty travel awards in passenger revenue as the points are used for travel. Revenue allocated to advertising and the remaining performance obligations, primarily marketing components, is recorded in other revenue over time as points are delivered. Total unrecognized revenue from future Free Spirit Program was $104.6 million and $81.3 million at December 31, 2023 and 2022, respectively. The current portion of this balance is recorded within air traffic liability and the long-term portion of this balance is recorded within deferred gains and other long-term liabilities in the accompanying consolidated balance sheets.

Points breakage. For points that the Company estimates are not likely to be redeemed ("breakage"), the Company recognizes the associated value proportionally during the period in which the remaining points are redeemed. Management uses statistical models to estimate breakage based on historical redemption patterns. A change in assumptions as to the period over which points are expected to be redeemed, the actual redemption activity for points or the estimated fair value of points expected to be redeemed could have an impact on revenues in the year in which the change occurs and in future years.

    Current activity of loyalty program. Points are combined in one homogeneous pool and are not separately identifiable. As such, revenue is composed of points that were part of the loyalty deferred revenue balance at the beginning of the period as well as points that were issued during the period.

Airframe and Engine Maintenance

Airframe and Engine Maintenance

The Company accounts for heavy maintenance and major overhaul under the deferral method whereby the cost of heavy maintenance and major overhaul is deferred and amortized until the earlier of the end of the useful life of the related asset, the end of the remaining lease term or the next scheduled heavy maintenance event.

The Company outsources certain routine, non-heavy maintenance functions under contracts that require payment on a utilization basis, primarily based on flight hours. Costs incurred for maintenance and repair under flight hour maintenance contracts, where labor and materials price risks have been transferred to the service provider, are expensed based on contractual payment terms. All other costs for routine maintenance of the airframes and engines are charged to expense as performed.

Leased Aircraft Return Costs

Leased Aircraft Return Costs

The Company's aircraft lease agreements often contain provisions that require the Company to return aircraft airframes, engines and other aircraft components to the lessor in a certain condition or pay an amount to the lessor based on the airframe and engine's actual return condition. Lease return costs include all costs that would be incurred at the return of the aircraft, including costs incurred to repair the airframe and engines to the required condition as stipulated by the lease. Lease return costs are recognized beginning when it is probable that such costs will be incurred and they can be estimated.

When determining the probability to accrue lease return costs, there are various estimated cost and factors which need to be considered such as the contractual terms of the lease agreement, current condition of the aircraft, the age of the aircraft at lease expiration, projected number of hours run on the engine at the time of return, and the number of projected cycles run on the airframe at the time of return, among others. Management assesses the need to accrue lease return costs periodically throughout the year or whenever facts and circumstances warrant an assessment. Lease return costs will generally be estimable closer to the end of the lease term but may be estimable earlier in the lease term depending on the contractual terms of the lease agreement and the timing of maintenance events for a particular aircraft.

Aircraft Fuel

Aircraft Fuel

Aircraft fuel expense includes jet fuel and associated into-plane costs, taxes, and oil, and realized and unrealized gains and losses associated with fuel derivative contracts, if any.

Advertising

Advertising

The Company expenses advertising and the production costs of advertising as incurred.

Income Taxes

Income Tax Receivable

Income tax receivable consists of amounts due from tax authorities for recovery of income taxes paid in prior periods.

Income Taxes

The Company accounts for income taxes using the asset and liability method. The Company records a valuation allowance to reduce the deferred tax assets reported if, based on the weight of the evidence, it is more likely than not that some

portion or all of the deferred tax assets will be not realized.

Stock-Based Compensation

Stock-Based Compensation

The Company recognizes cost of employee services received in exchange for awards of equity instruments based on the fair value of each instrument at the date of grant. For the majority of awards, compensation expense is recognized on a straight-line basis over the period during which an employee is required to provide service in exchange for an award. Certain awards have performance conditions that must be achieved prior to vesting and are expensed based on the expected achievement at each reporting period. The Company has issued restricted stock awards, performance share awards, market share awards and performance and market share awards. Restricted stock awards are valued at the fair value of the shares on the date of grant. The fair value of performance share awards based on a market condition and the market share awards are estimated through the use of a Monte Carlo simulation model. The fair value of performance share awards based on a performance condition is based on the fair value of the shares on the date of grant. The performance share awards based on a performance condition are evaluated at each report date and adjustments are made to stock-based compensation expense based on the number of shares deemed probable of issuance upon vesting. The fair value of the market and performance share awards are estimated through the use of a Monte Carlo simulation model and adjusted based on the number of shares deemed probable of issuance upon vesting.

Concentrations of Risk

Concentrations of Risk

The Company’s business may be adversely affected by increases in the price of aircraft fuel, the volatility of the price of aircraft fuel, or both. Aircraft fuel, one of the Company’s largest expenditures, represented approximately 31%, 34% and 28% of total operating expenses in 2023, 2022 and 2021, respectively.

The Company’s operations are largely concentrated in the southeast United States with Fort Lauderdale being the highest volume fueling point in the system. Gulf Coast Jet indexed fuel is the basis for a substantial majority of the Company’s fuel consumption. Any disruption to the oil production or refinery capacity in the Gulf Coast, as a result of weather or any other disaster, or disruptions in supply of jet fuel, dramatic escalations in the costs of jet fuel and/or the failure of fuel providers to perform under fuel arrangements for other reasons could have a material adverse effect on the Company’s financial condition and results of operations.

The Company’s operations will continue to be vulnerable to weather conditions (including hurricane season or snow and severe winter weather), which could disrupt service or create air traffic control problems. These events may result in decreased revenue and/or increased costs.

The Company relies on a limited number of vendors for the delivery of additional aircraft and engines - currently Airbus A320-family, single-aisle aircraft, powered by engines manufactured by IAE and Pratt & Whitney. Due to the relatively small size of the Company's fleet and high utilization rate, the unavailability of aircraft and engines, as well as the reduced capacity, resulting from delivery delays or performance issues from these vendors, could have a material adverse effect on the Company’s business, results of operations and financial condition. Refer to Note 3, Current Developments, for additional information on the Pratt & Whitney engine performance issues.
