UNITED AIRLINES HOLDINGS, INC. AND UNITED AIRLINES, INC.

COMBINED NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

United Airlines Holdings, Inc. (together with its consolidated subsidiaries, "UAL" or the "Company") is a holding company, and its principal, wholly-owned subsidiary is United Airlines, Inc. (together with its consolidated subsidiaries, "United"). This Quarterly Report on Form 10-Q is a combined report of UAL and United, including their respective consolidated financial statements. As UAL consolidates United for financial statement purposes, disclosures that relate to activities of United also apply to UAL, unless otherwise noted. United's operating revenues and operating expenses comprise nearly 100% of UAL's revenues and operating expenses. In addition, United comprises approximately the entire balance of UAL's assets, liabilities and operating cash flows. When appropriate, UAL and United are named specifically for their individual contractual obligations and related disclosures and any significant differences between the operations and results of UAL and United are separately disclosed and explained. We sometimes use the words "we," "our," "us," and the "Company" in this report for disclosures that relate to all of UAL and United.

The UAL and United unaudited condensed consolidated financial statements shown here have been prepared as required by the U.S. Securities and Exchange Commission (the "SEC"). Some information and footnote disclosures normally included in financial statements that comply with accounting principles generally accepted in the United States ("GAAP") have been condensed or omitted as permitted by the SEC. The financial statements include all adjustments, including normal recurring adjustments and other adjustments, which are considered necessary for a fair presentation of the Company's financial position and results of operations. The UAL and United financial statements should be read together with the information included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2020 (the "2020 Form 10-K"). The Company's quarterly financial data is subject to seasonal fluctuations. Historically its second and third quarter financial results have reflected higher travel demand, and were better than its first and fourth quarter financial results; however, see Part I, Item 2 of this report for additional discussion regarding trends associated with the matters discussed in the "Impact of the COVID-19 Pandemic" section below.

Impact of the COVID-19 Pandemic

The novel coronavirus (COVID-19) pandemic, together with the measures implemented or recommended by governmental authorities and private organizations in response to the pandemic, has had an adverse impact that has been material to the Company's business, operating results, financial condition and liquidity. The full extent of the ongoing impact of COVID-19 on the Company's longer-term operational and financial performance will depend on future developments, including those outside our control related to the efficacy and speed of vaccination programs in curbing the spread of the virus in different markets, the introduction and spread of new variants of the virus that may be resistant to currently approved vaccines and the continuation of existing or implementation of new government travel restrictions.

Capacity. The Company began experiencing a significant decline in international and domestic travel demand related to COVID-19 during the first quarter of 2020, and this reduction in demand has continued through the date of this report. However, since March 2021, the Company has seen increasing demand for travel both domestically and in countries where entry is permitted. The Company cut, relative to second quarter 2019 capacity, approximately 46% of its scheduled capacity for the second quarter of 2021 and expects its third quarter scheduled capacity to be down approximately 26% versus the third quarter of 2019. The Company will continue to monitor booking trends for future travel and adjust its capacity as needed.

Cost Reductions. The Company has identified various permanent structural cost reductions including improvements in labor efficiencies. During the first quarter of 2021, the Company offered voluntary leaves of absences to certain U.S.-based front-line employees. This program included (based on employee group, age and completed years of service) a partially-paid leave of absence with active health care coverage and travel privileges. Employees who separate from the Company after the end of such program receive certain separation benefits, such as post-employment health benefits and travel privileges. Approximately 4,500 employees elected to participate in this program, and it is expected that the majority of them will separate from employment at the end of their leave of absence. See Note 5 and Note 9 of this report for additional information on charges related to these programs.

Liquidity. The Company entered into a number of transactions to improve its liquidity and manage its capital. In the first half of 2021, the Company:

•issued, through a private offering to eligible purchasers, $4.0 billion in aggregate principal amount of two series of notes, consisting of $2.0 billion in aggregate principal amount of 4.375% senior secured notes due 2026 (the "2026 Notes") and $2.0 billion in aggregate principal amount of 4.625% senior secured notes due 2029 (the "2029 Notes" and, together with the 2026 Notes, the "Notes," and each a "series" of Notes);

•entered into a new Term Loan Credit and Guaranty Agreement (the "New Term Loan Facility") initially providing term loans (the "New Term Loans") up to an aggregate amount of $5.0 billion and a new Revolving Credit and

15

Guaranty Agreement (the "New Revolving Credit Facility" and, together with the New Term Loan Facility, the "New Loan Facilities") initially providing revolving loan commitments of up to $1.75 billion;

•repaid in full the $1.4 billion aggregate principal amount outstanding under the term loan facility (the "2017 Term Loan Facility") included in the Amended and Restated Credit and Guaranty Agreement, dated as of March 29, 2017 (the "Existing Credit Agreement");

•repaid in full the $1.0 billion aggregate principal amount outstanding under the revolving credit facility (the "2017 Revolving Credit Facility") included in the Existing Credit Agreement;

•repaid in full the $520 million aggregate principal amount outstanding under the Loan and Guarantee Agreement, dated as of September 28, 2020, among United, UAL, the U.S. Treasury Department ("Treasury") and the Bank of New York Mellon, as administrative agent, as amended (the "CARES Act Loan" and, together with the 2017 Term Loan Facility and the 2017 Revolving Credit Facility, the "Existing Loan Facilities"), which was entered into pursuant to the loan program established pursuant to the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act");

•entered into approximately $0.6 billion in new enhanced equipment trust certificates ("EETC"); and

•raised approximately $0.5 billion in net cash proceeds from the issuance and sale of UAL common stock.

In addition to the foregoing transactions, United entered into the following agreements with Treasury:

PSP2. On January 15, 2021, United entered into a Payroll Support Program Extension Agreement (the "PSP2 Agreement") with Treasury providing the Company with total funding of approximately $3.0 billion, pursuant to the Payroll Support Program established under Subtitle A of Title IV of Division N of the Consolidated Appropriations Act, 2021. These funds were used to pay for the wages, salaries and benefits of United employees, including the payment of lost wages, salaries and benefits to returning employees. Approximately $2.1 billion was provided as a direct grant and $870 million as indebtedness evidenced by a 10-year senior unsecured promissory note (the "PSP2 Note"). See Note 2 of this report for additional information on the warrants issued in connection with the PSP2 Note and Note 8 of this report for a discussion of the PSP2 Note. As a result of the PSP2 Agreement, the Company offered an opportunity to return to active employment to U.S. employees who were impacted by involuntary furloughs.

PSP3. On April 29, 2021, in connection with the Payroll Support Program established under Section 7301 of the American Rescue Plan Act of 2021, United entered into a Payroll Support Program 3 Agreement (the "PSP3 Agreement") with Treasury providing the Company with total funding of approximately $2.8 billion. Approximately $2.0 billion was provided as a direct grant and $810 million as indebtedness evidenced by a 10-year senior unsecured promissory note (the "PSP3 Note"). These funds will be used by United exclusively for the continuation of payment of its employee wages, salaries and benefits. See Note 2 of this report for additional information on the warrants issued in connection with the PSP3 Note and Note 8 of this report for a discussion of the PSP3 Note.

United Next. On June 27, 2021, United entered into a supplemental agreement to that certain Purchase Agreement, dated May 15, 2018 with The Boeing Company ("Boeing") for a firm narrowbody aircraft order of 200 Boeing 737 MAX aircraft. The order consists of 150 Boeing 737 MAX 10s and 50 Boeing 737 MAX 8s. Also on June 27, 2021, United entered into an amendment to that certain Purchase Agreement, dated December 3, 2019 with Airbus S.A.S ("Airbus") for a firm narrowbody aircraft order of 70 Airbus A321neo aircraft. The firm orders of 200 Boeing 737 MAX aircraft and 70 Airbus A321neo aircraft are expected to be delivered starting in 2023 through 2028 and 2026, respectively.

NOTE 1 - REVENUE

Revenue by Geography. The table below presents the Company's operating revenue by principal geographic region (as defined by the U.S. Department of Transportation) (in millions):

	Three Months Ended June 30,				Six Months Ended June 30,
	2021		2020		2021		2020
Domestic (U.S. and Canada)	$	3,767	$	925	$	5,878	$	6,003
Atlantic	585		219		995		1,434
Pacific	392		258		700		1,064
Latin America	727		73		1,119		953
Total	$	5,471	$	1,475	$	8,692	$	9,454

Advance Ticket Sales. All tickets sold at any given point in time have travel dates through the next 12 months. The Company defers amounts related to future travel in its Advance ticket sales liability account. The Company's Advance ticket sales liability also includes credits issued to customers on electronic travel certificates ("ETCs") and future flight credits ("FFCs"), primarily for ticket cancellations, which can be applied towards a purchase of a new ticket. In February 2021, the Company extended the expiration dates for all tickets issued between May 1, 2019 and March 31, 2021 to March 31, 2022. As of June 30, 2021, the Company's Advance ticket sales liability included $2.6 billion related to these ETCs and FFCs. The Company is unable to estimate the amount of the ETCs and FFCs that will be used within the next 12 months and has classified the entire amount of the Advance ticket sales liability in current liabilities even though some of the ETCs could be used after the next 12 months. Also, the Company is unable to estimate the amount of the June 30, 2021 Advance ticket sales that will be recognized in revenue in 2021 compared to amounts refunded to customers or exchanged into ETCs.

The Company records breakage revenue on the travel date for its estimate of tickets that will expire unused. To determine breakage, the Company uses its historical experience with refundable and nonrefundable expired tickets and other facts, such as recent aging trends, program changes and modifications that could affect the ultimate expiration patterns of tickets. Given the uncertainty of travel demand caused by COVID-19, a significant portion of the ETCs and FFCs may expire unused in future periods and get recognized as breakage. The Company will update its breakage estimates as future information is received.

In the three and six months ended June 30, 2021, the Company recognized approximately $1.5 billion and $1.4 billion, respectively, of passenger revenue for tickets that were included in Advance ticket sales at the beginning of those periods. In the three and six months ended June 30, 2020, the Company recognized approximately $0.5 billion and $2.8 billion, respectively, of passenger revenue for tickets that were included in Advance ticket sales at the beginning of those periods.

Ancillary Fees. The Company charges fees, separately from ticket sales, for certain ancillary services that are directly related to passengers' travel, such as baggage fees, premium seats, inflight amenities and other ticket-related fees. These ancillary fees are part of the travel performance obligation and, as such, are recognized as passenger revenue when the travel occurs. The Company recorded $499 million and $807 million of ancillary fees within passenger revenue in the three and six months ended June 30, 2021, respectively. The Company recorded $71 million and $776 million of ancillary fees within passenger revenue in the three and six months ended June 30, 2020, respectively.

Frequent Flyer Accounting. The table below presents a roll forward of Frequent flyer deferred revenue (in millions):

	Three Months Ended June 30,				Six Months Ended June 30,
	2021		2020		2021		2020
Total Frequent flyer deferred revenue - beginning balance	$	6,109	$	5,488	$	5,975	$	5,276
Total miles awarded	360		228		632		787
Travel miles redeemed (Passenger revenue)	(267)		(34)		(390)		(356)
Non-travel miles redeemed (Other operating revenue)	(17)		(12)		(32)		(37)
Total Frequent flyer deferred revenue - ending balance	$	6,185	$	5,670	$	6,185	$	5,670

In the three and six months ended June 30, 2021, the Company recognized, in Other operating revenue, $449 million and $811 million, respectively, related to the marketing, advertising, non-travel miles redeemed (net of related costs) and other travel-related benefits of the mileage revenue associated with our various partner agreements including, but not limited to, our JPMorgan Chase Bank, N.A. co-brand agreement. The Company recognized $339 million and $869 million, respectively, in the three and six months ended June 30, 2020, related to those agreements. The portion related to the MileagePlus miles awarded of the total amounts received from our various partner agreements is deferred and presented in the table above as an increase to the frequent flyer liability. We determine the current portion of our frequent flyer liability based on expected redemptions in the

17

next 12 months. Given the uncertainty in travel demand caused by COVID-19, we currently estimate a large percentage of award redemptions will occur beyond 12 months; however, this estimate may change as travel demand and award redemptions become clearer in future periods.

NOTE 2 - LOSS PER SHARE

The computations of UAL's basic and diluted loss per share are set forth below (in millions, except per share amounts):

	Three Months Ended June 30,				Six Months Ended June 30,
	2021		2020		2021		2020
Loss available to common stockholders	$	(434)	$	(1,627)	$	(1,791)	$	(3,331)
Weighted-average shares outstanding, basic and diluted	323.6		280.7		320.1		264.6
Loss per share, basic and diluted	$	(1.34)	$	(5.79)	$	(5.60)	$	(12.59)

During the first quarter of 2021, UAL entered into a warrant agreement with Treasury pursuant to which UAL issued to Treasury warrants to purchase up to approximately 2.0 million shares of UAL common stock (the "PSP2 Warrants"). The PSP2 Warrants have a strike price of $43.26 per share. The PSP2 Warrants will expire five years after issuance and are exercisable either through net share settlement in cash or in shares of UAL common stock, at UAL's option. The relative fair value of the PSP2 Warrants was calculated using a Black-Scholes options pricing model, and approximately $56 million was recorded within stockholders' equity with an offset to the CARES Act grant credit. During the second quarter of 2021, UAL also entered into a warrant agreement with Treasury, pursuant to which UAL issued to Treasury warrants to purchase up to approximately 1.5 million shares of UAL common stock (the "PSP3 Warrants"). The PSP3 Warrants have a strike price of $53.92 per share. The PSP3 Warrants will expire five years after issuance and are exercisable either through net share settlement in cash or in shares of UAL common stock, at UAL's option. The relative fair value of the PSP3 Warrants was calculated using a Black-Scholes options pricing model, and approximately $43 million was recorded within stockholders' equity with an offset to the CARES Act grant credit.

The PSP2 Warrants and PSP3 Warrants contain customary anti-dilution provisions and registration rights and are freely transferable. Pursuant to the terms of the PSP2 Warrants and PSP3 Warrants, warrant holders do not have any voting rights. As of June 30, 2021, the Company had the following warrants outstanding:

Warrant Description		Number of Shares of UAL Common Stock (in millions)	Exercise Price		Expiration Dates
PSP1 Warrants (a)		4.8	$	31.50	4/20/2025	—	9/30/2025
CARES Act Loan Warrants		1.7	31.50		9/28/2025
PSP2 Warrants		2.0	43.26		1/15/2026	—	4/29/2026
PSP3 Warrants		1.5	53.92		4/29/2026	—	6/10/2026
Total		10.0
(a)	Warrants issued in connection with the $1.5 billion 10-year senior unsecured promissory note with Treasury provided under the Payroll Support Program of the CARES Act ("PSP1").

On June 15, 2020, UAL entered into an equity distribution agreement with Citigroup Global Markets Inc., BofA Securities, Inc. and J.P. Morgan Securities LLC, relating to the issuance and sale from time to time by UAL (the "2020 ATM Offering"), of up to 28 million shares of UAL common stock. In the first quarter of 2021, the Company sold approximately 7 million shares at an average price of $42.98 per share, with net proceeds to the Company of approximately $282 million. With these sales, the Company sold all of the shares authorized under the 2020 ATM Offering.

On March 3, 2021, the Company entered into an equity distribution agreement (the "Distribution Agreement") with Morgan Stanley & Co. LLC, AmeriVet Securities, Inc., Barclays Capital Inc., BofA Securities, Inc., BBVA Securities Inc., BNP Paribas Securities Corp., Citigroup Global Markets Inc., Credit Agricole Securities (USA) Inc., Credit Suisse Securities (USA) LLC, Deutsche Bank Securities Inc., Goldman Sachs & Co. LLC, J.P. Morgan Securities LLC, Loop Capital Markets LLC and Wells Fargo Securities, LLC (collectively, the "Managers"), relating to the issuance and sale from time to time by UAL (the "2021 ATM Offering"), through the Managers, of up to 37 million shares of UAL common stock (the "2021 ATM Shares"). Sales of the 2021 ATM Shares under the Distribution Agreement may be made in any transactions that are deemed to be "at the market

18

offerings" as defined in Rule 415 under the Securities Act of 1933, as amended. Under the terms of the Distribution Agreement, UAL may also sell the 2021 ATM Shares to any Manager, as principal for its own account, at a price agreed upon at the time of sale. If UAL sells the 2021 ATM Shares to a Manager as principal, UAL will enter into a separate terms agreement with such Manager. During the six months ended June 30, 2021, approximately 4 million shares were sold in the 2021 ATM Offering at an average price of $57.50 per share, with net proceeds to the Company totaling approximately $250 million.

In 2020 and 2021, the Company offered several voluntary leave programs and voluntary separation programs ("Voluntary Programs") to certain eligible employees, which in some cases included a partially-paid leave of absence with active health benefits and travel privileges. Under these Voluntary Programs, employees generally separated (or will separate) from employment with certain post-employment health benefits and travel privileges.

Included in the Voluntary Programs offered during the first quarter of 2021, the Company offered special separation benefits in the form of additional subsidies for retiree medical costs for certain U.S.-based front-line employees. The subsidies are in the form of a one-time contribution to a notional Retiree Health Account of $125,000 for full-time employees and $75,000 for part-time employees. As a result, the Company recorded $46 million for those additional benefits in the three months ended March 31, 2021.

During the second quarter of 2020, the Company offered Voluntary Programs to its U.S.-based front-line employees, excluding pilots, and management and administrative employees. Included in these Voluntary Programs, the Company offered special separation benefits in the form of additional years of pension service and additional subsidies for retiree medical costs (based on employee group, age and completed years of service). As a result, the Company recorded, in the second quarter of 2020, $35 million and $125 million, respectively, for those additional benefits. Also, the Company recognized a $71 million settlement loss related to the defined benefit pension plan covering certain U.S. non-pilot employees in the second quarter of 2020.

Share-Based Compensation. During the six months ended June 30, 2021, UAL's Board of Directors and stockholders approved the United Airlines Holdings, Inc. 2021 Incentive Compensation Plan (the "2021 Plan"). The 2021 Plan is an incentive compensation plan that allows the Company to use different forms of equity incentives to attract, retain and reward officers and employees. Under the 2021 Plan, the Company may grant: nonqualified stock options; incentive stock options (within the

20

meaning of Section 422 of the Internal Revenue Code of 1986); stock appreciation rights ("SARs"); restricted shares; restricted stock units ("RSUs"); performance units; cash incentive awards and other equity-based and equity-related awards. An award (other than an option, SAR or cash incentive award) may provide the holder with dividends or dividend equivalents. The 2021 Plan replaces the United Continental Holdings, Inc. 2017 Incentive Compensation Plan (the "2017 Plan"). Any awards granted under the 2017 Plan prior to the approval of the 2021 Plan remain in effect pursuant to their terms. Awards may not be granted under the 2021 Plan after May 26, 2031.

During the six months ended June 30, 2021, UAL granted share-based compensation awards pursuant to both the 2017 Plan and the 2021 Plan. These share-based compensation awards included 2.9 million RSUs, consisting of 1.3 million time-vested RSUs and 1.6 million short-term performance-based RSUs. A majority of the time-vested RSUs vest equally in 25% increments every 6 months over a two-year period from the date of grant. The short-term performance-based RSUs vest upon the achievement of established goals based on financial and customer satisfaction metrics for the performance period January 1, 2021 to December 31, 2021. RSUs are generally equity awards settled in stock for domestic employees and liability awards settled in cash for international employees. The cash payments are based on the 20-day average closing price of UAL common stock immediately prior to the vesting date.

The table below presents information related to share-based compensation (in millions):

Investments presented in the table above have the same fair value as their carrying value.

Restricted cash - current — Primarily includes $217 million of cash collateral for a standby letter of credit associated with guarantees related to the BRW Term Loan (as defined below). See Note 7 of this report for additional information on the BRW Term Loan and guarantees. The balance also includes amounts to be used for the payment of fees, principal and interest on senior secured notes and a secured term loan facility (the "MileagePlus Financing") secured by substantially all of the assets of Mileage Plus Holdings, LLC, a direct wholly-owned subsidiary of United.

Restricted cash - non-current — Primarily includes collateral associated with the MileagePlus Financing, collateral for letters of credit and collateral associated with facility leases and other insurance-related obligations.

Short-term investments — The short-term investments shown in the table above are classified as available-for-sale. As of June 30, 2021, corporate debt securities have remaining maturities of less than two years, asset-backed securities have remaining maturities of less than one year to approximately nine years and U.S. government and agency notes have maturities of less than one year.

21

Equity securities — Equity securities represent United's investment in Azul Linhas Aéreas Brasileiras S.A. ("Azul"), consisting of approximately 8% of Azul's outstanding preferred shares (representing approximately 2% of the total capital stock of Azul), and United's ownership of less than 1% of the outstanding Class A common shares of Clear Secure, Inc. (formerly, Alclear, Inc.) ("Clear"). As of June 30, 2021, the carrying value of United's investment in Azul and Clear was $238 million and $31 million, respectively.

Warrants — Represents vested warrants for the purchase of 2.4 million shares of Class A common shares of Clear and for the purchase of 4.7 million common shares from Archer Aviation Inc. ("Archer"). The initial value of the warrants received from Archer is recorded as a deferred credit that will be recognized as a reduction to the cost of the aircraft received in future periods.

Other fair value information. The table below presents the carrying values and estimated fair values of financial instruments not presented in the tables above (in millions). Carrying amounts include any related discounts, premiums and issuance costs:

	June 30, 2021										December 31, 2020
	Carrying Amount		Fair Value								Carrying Amount		Fair Value
			Total		Level 1		Level 2		Level 3				Total		Level 1		Level 2		Level 3
Long-term debt	$	34,184	$	35,798	$	—	$	30,268	$	5,530	$	26,747	$	27,441	$	—	$	21,985	$	5,456

Fair value of the financial instruments included in the tables above was determined as follows:

Description	Fair Value Methodology
Cash and cash equivalents	The carrying amounts approximate fair value because of the short-term maturity of these assets.
Short-term investments, Equity securities and Restricted cash (current and non-current)	Fair value is based on (a) the trading prices of the investment or similar instruments, (b) an income approach, which uses valuation techniques to convert future amounts into a single present amount based on current market expectations about those future amounts when observable trading prices are not available, or (c) broker quotes obtained by third-party valuation services.
Other assets	Fair value is determined utilizing the Black-Scholes options pricing model or observable market prices.
Long-term debt	Fair values were based on either market prices or the discounted amount of future cash flows using our current incremental rate of borrowing for similar liabilities or assets.

Avianca Loan. Avianca Holdings S.A. ("AVH") and certain of its affiliates filed voluntary reorganization proceedings under Chapter 11 of the United States Bankruptcy Code in the U.S. Bankruptcy Court for the Southern District of New York on May 10, 2020 (the "AVH Reorganization Proceedings"). As part of the AVH Reorganization Proceedings, the Company has a debtor-in-possession ("DIP") term loan ("DIP Loan") receivable under the terms of the DIP credit agreement. The DIP Loan is not convertible. It bears paid-in-kind interest at a rate of 14.5% per annum and has a scheduled maturity date in November 2021. The DIP Loan becomes immediately payable upon AVH's emergence from bankruptcy, in either cash or shares of AVH stock, at AVH's election. As of June 30, 2021, the DIP Loan had a balance of $170 million and was recorded in Receivables on the Company's consolidated balance sheet.

Investments in Regional Carriers. United holds investments in several regional carriers that fly or used to fly for the Company as United Express under its capacity purchase agreements ("CPAs"). The combined carrying value of the investments was approximately $152 million as of June 30, 2021. United accounts for each investment using the equity method. Each investment and United's ownership stake are listed below.

•Champlain Enterprises, LLC ("Champlain"). United owns a 40% minority ownership stake in Champlain. Champlain does business as CommutAir. CommutAir currently operates 70 regional aircraft under a CPA that has a term through 2026.

•Republic Airways Holdings Inc. ("Republic"). United holds a 19% minority interest in Republic. Republic is the parent company of Republic Airways Inc. Republic currently operates 66 regional aircraft under a CPA that has a term through 2029.

•ManaAir, LLC ("ManaAir"). United holds a 49.9% minority ownership stake in ManaAir. ManaAir is the parent company of ExpressJet Airlines LLC ("ExpressJet"). The Company terminated its CPA with ExpressJet. ExpressJet flew its last commercial flight, on behalf of United, on September 30, 2020.

22

Other Investments. United holds other investments that are recorded at cost less impairment, adjusted for observable price changes in orderly transactions for an identical or similar investment of the same issuer. As of June 30, 2021, United held these major investments:

•Fulcrum BioEnergy, Inc. ("Fulcrum"). United owns approximately 7% of the preferred shares (representing approximately 6% of the total capital stock) of Fulcrum, a company that is developing a process for transforming municipal solid waste into transportation fuels, including jet fuel and diesel. As of June 30, 2021, the carrying value of United's investment was $51 million.

The values of the warrants and the note are recorded as deferred credits that will be recognized as a reduction to the cost of the aircraft received in future periods.

NOTE 7 - COMMITMENTS AND CONTINGENCIES

Commitments. As of June 30, 2021, United had firm commitments and options to purchase aircraft from Boeing and Airbus as presented in the table below:

		Scheduled Aircraft Deliveries
Aircraft Type	Number of Firm  Commitments (a)	Last Six Months of 2021	2022	2023	After 2023
Airbus A321XLR	50	—	—	—	50
Airbus A321neo	70	—	—	16	54
Airbus A350	45	—	—	—	45
Boeing 737 MAX	380	13	40	122	205
Boeing 787	8	8	—	—	—
(a) United also has options and purchase rights for additional aircraft.

The aircraft listed in the table above are scheduled for delivery through 2030. To the extent the Company and the aircraft manufacturers with whom the Company has existing orders for new aircraft agree to modify the contracts governing those orders, or to the extent rights are exercised pursuant to the relevant agreements to modify the timing of deliveries, the amount and timing of the Company's future capital commitments could change.

United also has an agreement to purchase six used Boeing 737-700 aircraft, which it intends to sell, with expected delivery dates in 2021. In addition, United has an agreement to purchase 11 used Airbus A319 aircraft, which it intends to sell, with expected delivery dates in 2021 and 2022.

In 2020, United entered into agreements with third parties to finance through sale and leaseback transactions new Boeing model 787 aircraft and Boeing model 737 MAX aircraft subject to purchase agreements between United and Boeing. In connection with the delivery of each aircraft from Boeing, United assigned its right to purchase such aircraft to the buyer, and simultaneous with the buyer's purchase from Boeing, United entered into a long-term lease for such aircraft with the buyer as lessor. Eleven Boeing model aircraft were delivered in the first half of 2021 under these transactions (and each is presently subject to a long-term lease to United). Remaining aircraft in the agreements are scheduled to be delivered in the last six months of 2021. Upon delivery of aircraft in these sale and leaseback transactions in 2021, the Company accounted for seven of these aircraft, which have a repurchase option at a price other than fair value, as part of Flight equipment on the Company's consolidated balance sheet and the related obligation recorded in Other current liabilities and Other financial liabilities from sale-leasebacks (noncurrent) since they do not qualify for sale recognition. The remaining four aircraft that qualified for sale recognition were recorded as Operating lease right-of-use assets and Current/Long-term obligations under operating leases on the Company's consolidated balance sheet after recognition of related gains on such sale.

The table below summarizes United's commitments as of June 30, 2021, which include aircraft and related spare engines, aircraft improvements and all non-aircraft capital commitments (in billions):

Last six months of 2021	$	3.1

Regional CPAs. The table below summarizes the Company's expected future payments through the end of the terms of our CPAs, excluding aircraft ownership costs and variable pass-through costs such as fuel and landing fees, among others. Our future commitments under our CPAs are dependent on numerous variables, and are, therefore, difficult to predict. We have set forth below estimates based on our current assumptions of our anticipated level of flight activity or any contractual minimum utilization levels if applicable, whichever is higher. Based on these assumptions as of June 30, 2021, our estimated future payments through the end of the terms of our CPAs are presented in the table below (in billions):

Last six months of 2021	$	1.1
2022	2.1
2023	1.9
2024	1.8
2025	1.5
After 2025	3.7
	$	12.1

Guarantees. As of June 30, 2021, United is the guarantor of approximately $1.9 billion in aggregate principal amount of tax-exempt special facilities revenue bonds and interest thereon. These bonds, issued by various airport municipalities, are payable solely from rentals paid under long-term agreements with the respective governing bodies. The leasing arrangements associated with these obligations are accounted for as operating leases recognized on the Company's consolidated balance sheet with the associated expense recorded on a straight-line basis over the expected lease term. All of these bonds are due between 2023 and 2038.

In November 2018, United, as lender, entered into a Term Loan Agreement (the "BRW Term Loan Agreement") with, among others, BRW Aviation Holding LLC and BRW Aviation LLC ("BRW"), as guarantor and borrower, respectively. BRW Aviation Holding LLC and BRW are affiliates of Synergy Aerospace Corporation, and BRW is the majority shareholder of AVH. Pursuant to the BRW Term Loan Agreement, United provided to BRW a $456 million term loan (the "BRW Term Loan"). In November 2018, in connection with funding the BRW Term Loan Agreement, the Company entered into an agreement with Kingsland Holdings Limited ("Kingsland"), AVH's largest minority shareholder, pursuant to which, in return for Kingsland's pledge of its 144.8 million common shares of AVH (which are eligible to be converted into the same number of preferred shares, which may be deposited with the depositary for AVH's American Depositary Receipts ("ADRs"), the class of AVH securities that trades on the NYSE, in exchange for 18.1 million ADRs) and its consent to BRW's pledge of its AVH common shares to United under the BRW Term Loan Agreement and related agreements, United (1) granted to Kingsland the right to put its AVH common shares to United at market price on the fifth anniversary of the BRW Term Loan Agreement or upon certain sales of AVH common shares owned by BRW, including upon a foreclosure of United's security interest, and (2) guaranteed BRW's obligation to pay Kingsland the difference if the market price of AVH common shares on the fifth anniversary, or upon any such sale, as applicable, is less than $12 per ADR on the NYSE, for an aggregate maximum possible combined put payment and guarantee amount on the fifth anniversary of $217 million. Due to AVH's financial uncertainty and subsequent bankruptcy filing in 2019, the Company recorded the full amount of the guarantee as a liability. Additionally, the Company posted $217 million as cash collateral for a standby letter of credit in favor of Citibank, N.A. that serves as security for a loan from Citibank to Kingsland (recorded in Restricted cash – current on the Company's consolidated balance sheet). Any drawings under the letter of credit would offset the Company's maximum possible put and guarantee payment to Kingsland by an equal amount. The posting of this collateral, and any potential credit against the Company's put and guarantee payment, are entirely related to the original transactions entered in 2018 and do not represent any new or incremental investment.

As of June 30, 2021, United is the guarantor of $113 million of aircraft mortgage debt issued by one of United's regional carriers. The aircraft mortgage debt is subject to similar increased cost provisions as described below for the Company's debt, and the Company would potentially be responsible for those costs under the guarantees.

24

Increased Cost Provisions. In United's financing transactions that include loans in which United is the borrower, United typically agrees to reimburse lenders for any reduced returns with respect to the loans due to any change in capital requirements and, in the case of loans with respect to which the interest rate is based on the London Interbank Offered Rate (LIBOR), for certain other increased costs that the lenders incur in carrying these loans as a result of any change in law, subject, in most cases, to obligations of the lenders to take certain limited steps to mitigate the requirement for, or the amount of, such increased costs. At June 30, 2021, the Company had $13.4 billion of floating rate debt with remaining terms of up to approximately 11 years that are subject to these increased cost provisions. In several financing transactions involving loans or leases from non-U.S. entities, with remaining terms of up to approximately 11 years and an aggregate balance of $10.2 billion, the Company bears the risk of any change in tax laws that would subject loan or lease payments thereunder to non-U.S. entities to withholding taxes, subject to customary exclusions.

Labor Negotiations. As of June 30, 2021, the Company had approximately 84,400 employees, of whom approximately 85% were represented by various U.S. labor organizations. This total includes approximately 4,500 front-line employees who elected to voluntarily separate from the Company pursuant to the first quarter 2021 Company-offered Voluntary Programs but who still remained on pay and benefit continuation as of June 30, 2021.

Credit Card Processing Agreements. The Company has agreements with financial institutions that process customer credit card transactions for the sale of air travel and other services. Under certain of the Company's credit card processing agreements, the financial institutions in certain circumstances have the right to require that the Company maintain a reserve equal to a portion of advance ticket sales that has been processed by that financial institution, but for which the Company has not yet provided the air transportation. Such financial institutions may require cash or other collateral reserves to be established or withholding of payments related to receivables to be collected, including if the Company does not maintain certain minimum levels of unrestricted cash, cash equivalents and short-term investments.

NOTE 8 - DEBT

On April 21, 2021, United paid all amounts outstanding under the 2017 Revolving Credit Facility and the 2017 Term Loan Facility, terminated the 2017 Revolving Credit Facility and the 2017 Term Loan Facility and entered into the New Loan Facilities described below. As of June 30, 2021, United had $1.75 billion available for borrowing under the New Revolving Credit Facility at any time until April 21, 2025.

EETCs. In February 2021, United created EETC pass-through trusts which issued pass-through certificates. The proceeds from the issuance of the pass-through certificates are used to purchase equipment notes issued by United and secured by its aircraft financed with the proceeds of such notes. The Company records the debt obligation upon issuance of the equipment notes rather than upon the initial issuance of the pass-through certificates. The pass-through certificates represent fractional undivided interests in the respective pass-through trusts and are not obligations of United. The payment obligations under the equipment notes are those of United. Proceeds received from the sale of pass-through certificates are initially held by a depositary in escrow for the benefit of the certificate holders until United issues equipment notes to the trust, which purchases such notes with a portion of the escrowed funds. These escrowed funds are not guaranteed by United and are not reported as debt on our consolidated balance sheet because the proceeds held by the depositary are not United's assets. Certain details of the pass-through trusts with proceeds received from issuance of debt in 2021 are as follows (in millions, except stated interest rate):

EETC Issuance Date	Class	Face Amount		Stated interest rate	Total proceeds received from issuance of debt		Total debt recorded as of June 30, 2021
February 2021	B	$	600	4.88%	$	600	$	600

PSP2 Note. During the six months ended June 30, 2021, UAL issued an $870 million PSP2 Note to Treasury evidencing senior unsecured indebtedness of UAL. The PSP2 Note is guaranteed by United and will mature ten years after issuance on January 15, 2031 (the "PSP2 Note Maturity Date"). If any subsidiary of UAL (other than United) guarantees other unsecured indebtedness of UAL with a principal balance in excess of a specified amount, then such subsidiary shall be required to guarantee the obligations of UAL under the PSP2 Note. UAL may, at its option, prepay the PSP2 Note, at any time, and from time to time, at par. UAL is required to prepay the PSP2 Note upon the occurrence of certain change of control triggering events. The PSP2 Note does not require any amortization and is to be repaid in full on the PSP2 Note Maturity Date. Interest on the PSP2 Note is payable semi-annually in arrears on the last business day of March and September of each year, beginning on March 31, 2021, at a rate of 1.00% in years 1 through 5, and at the Secured Overnight Financing Rate (SOFR) plus 2.00% in years 6 through 10.

PSP3 Note. During the second quarter of 2021, UAL issued an $810 million PSP3 Note to Treasury evidencing senior unsecured indebtedness of UAL. The PSP3 Note is guaranteed by United and will mature ten years after issuance on April 29, 2031 (the "PSP3 Note Maturity Date"). If any subsidiary of UAL (other than United) guarantees other unsecured indebtedness

25

of UAL with a principal balance in excess of a specified amount, then such subsidiary shall be required to guarantee the obligations of UAL under the PSP3 Note. UAL may, at its option, prepay the PSP3 Note, at any time, and from time to time, at par. UAL is required to prepay the PSP3 Note upon the occurrence of certain change of control triggering events. The PSP3 Note does not require any amortization and is to be repaid in full on the PSP3 Note Maturity Date. Interest on the PSP3 Note is payable semi-annually in arrears on the last business day of March and September of each year, beginning on September 30, 2021, at a rate of 1.00% in years 1 through 5, and at the Secured Overnight Financing Rate (SOFR) plus 2.00% in years 6 through 10.

Notes. On April 21, 2021, United issued, through a private offering to eligible purchasers, $4.0 billion in aggregate principal amount of two series of Notes, consisting of $2.0 billion in aggregate principal amount of the 2026 Notes and $2.0 billion in aggregate principal amount of the 2029 Notes. The 2026 Notes, issued at a price of 100% of their principal amount, bear interest at a rate of 4.375% per annum and will mature on April 15, 2026. The 2029 Notes, issued at a price of 100% of their principal amount, bear interest at a rate of 4.625% per annum and will mature on April 15, 2029. The Notes are guaranteed on an unsecured basis by UAL.

New Loan Facilities. Concurrently with the closing of the offering of the Notes, United also entered into the New Loan Facilities, consisting of the New Term Loan Facility initially providing New Term Loans up to an aggregate amount of $5.0 billion and the New Revolving Credit Facility initially providing revolving loan commitments of up to $1.75 billion. United borrowed the full amount of the New Term Loans on April 21, 2021, which bear interest at a variable rate equal to LIBOR (but not less than 0.75% per annum) plus a margin of 3.75% per annum. The principal amount of the New Term Loan Facility must be repaid in consecutive quarterly installments of 0.25% of the original principal amount thereof with the balance due at maturity. Borrowings under the New Revolving Credit Facility bear interest at a variable rate equal to LIBOR plus a margin of 3.00% to 3.50% per annum. United pays a commitment fee equal to 0.75% per annum on the undrawn amount available under the New Revolving Credit Facility.

United used the net proceeds from the offering of the Notes and borrowings under the New Term Loan Facility (i) to repay in full all of the Existing Loan Facilities, including the $1.4 billion aggregate principal amount outstanding under the 2017 Term Loan Facility, the $1.0 billion aggregate principal amount outstanding under the 2017 Revolving Credit Facility and the $520 million aggregate principal amount outstanding under the CARES Act Loan, (ii) to pay fees and expenses relating to the offering of the Notes and (iii) for United's general corporate purposes. As a result of such repayments, the Existing Loan Facilities were terminated on April 21, 2021 and no further borrowings may be made thereunder.

The Notes and the New Loan Facilities are secured on a senior basis by security interests granted by United to the collateral trustee for the benefit of the holders of the Notes and the lenders under the New Loan Facilities, among other parties, on the following: (i) all of United's route authorities granted by the U.S. Department of Transportation to operate scheduled service between any international airport located in the United States and any international airport located in any country other than the United States (except Cuba), (ii) United's rights to substantially all of its landing and take-off slots at foreign and domestic airports, including at John F. Kennedy International Airport, LaGuardia Airport and Ronald Reagan Washington National Airport (subject to certain exclusions), and (iii) United's rights to use or occupy space at airport terminals, each to the extent necessary at the relevant time for servicing scheduled air carrier service authorized by an applicable route authority.

As of June 30, 2021, UAL and United were in compliance with their respective debt covenants.

2021

CARES Act grant. During the six months ended June 30, 2021, the Company received approximately $5.8 billion in funding pursuant to the PSP2 Agreement and the PSP3 Agreement, which included an approximately $1.7 billion unsecured loan. The Company recorded $1.1 billion and $2.9 billion as grant income in Special charges (credits) during the three and six months ended June 30, 2021, respectively. The Company also recorded $52 million and $99 million for the PSP2 Warrants and PSP3 Warrants issued to Treasury as part of the PSP2 Agreement and PSP3 Agreement, within stockholders' equity, as an offset to the grant income in the three and six months ended June 30, 2021, respectively. The Company deferred recognition of $1.1 billion of the funds received under the PSP3 Agreement as of June 30, 2021 as the funds can only be used for the payment of eligible salaries, wages and benefits. The Company expects the remainder of the PSP3 Agreement funds will be recognized as income in the third quarter of 2021.

Impairment of assets. During the three and six months ended June 30, 2021, the Company recorded $59 million of impairments primarily related to 64 Embraer EMB 145LR aircraft and related engines that United retired from its regional aircraft fleet. The decision to retire these aircraft was triggered by the United Next aircraft order. In February 2021, the Company voluntarily and temporarily removed all 52 Boeing 777-200/200ER aircraft powered by Pratt & Whitney 4000 series engines from its schedule due to an engine failure incident with one of its aircraft. The Company viewed this incident as an indicator of potential impairment. Accordingly, as required under relevant accounting standards, United performed forecasted cash flow analyses and determined that the carrying value of the Boeing 777-200/200ER fleet is expected to be recoverable from future cash flows expected to be generated by that fleet and, consequently, no impairment was recorded.

Severance and benefit costs. During the three and six months ended June 30, 2021, the Company recorded charges of $11 million and $428 million, respectively, related to pay continuation and benefits-related costs provided to employees who chose to voluntarily separate from the Company. The Company offered, based on employee group, age and completed years of service, pay continuation, health care coverage, and travel benefits. Approximately 4,500 employees elected to voluntarily separate from the Company.

(Gains) losses on sale of assets and other special charges. During the three and six months ended June 30, 2021, the Company recorded charges of $61 million and $77 million, respectively, primarily related to incentives for certain of its front-line employees to receive a COVID-19 vaccination and the termination of the lease associated with three floors of its headquarters at the Willis Tower in Chicago in the first quarter of 2021.

Nonoperating unrealized losses on investments, net. During the three and six months ended June 30, 2021, the Company recorded $90 million of gains related to its equity investments and warrants in the equity of Clear. Clear undertook its initial public stock offering in June 2021. Also during the three and six months ended June 30, 2021, the Company recorded gains of $57 million and $35 million, respectively, primarily for the change in the market value of its investment in Azul.

27

Nonoperating debt extinguishment and modification fees. During the three and six months ended June 30, 2021, the Company recorded $62 million of charges for fees and discounts related to the issuance of the New Loan Facilities and the prepayment of the Existing Loan Facilities.

Nonoperating special termination benefits. During the six months ended June 30, 2021, as part of the first quarter Voluntary Programs, the Company recorded $46 million of special termination benefits in the form of additional subsidies for retiree medical costs for certain U.S.-based front-line employees. The subsidies were in the form of a one-time contribution into the employee's Retiree Health Account of $125,000 for full-time employees and $75,000 for part-time employees.

2020

CARES Act grant. During the three and six months ended June 30, 2020, the Company received approximately $4.5 billion in funding pursuant to PSP1, which consisted of a $3.2 billion grant and a $1.3 billion unsecured loan. The Company recognized $1.6 billion of the grant as a credit to Special charges (credit) and $57 million in warrants issued to Treasury, within stockholder's equity, as an offset to the grant income.

Impairment of assets. During the three and six months ended June 30, 2020, the Company recorded impairment charges of $80 million and $130 million, respectively, for its China routes, which was primarily caused by the COVID-19 pandemic and the Company's subsequent suspension of flights to China.

Severance and benefit costs. During the three and six months ended June 30, 2020, the Company recorded $63 million related to pay continuation and benefits provided to employees who chose to voluntarily separate from the Company.

Nonoperating unrealized losses on investments, net. During the three and six months ended June 30, 2020, the Company recorded gains of $9 million and losses of $310 million, respectively. The losses in the six months ended June 30, 2020 were primarily due to the $284 million decrease in the market value of the Company's investment in Azul and the $24 million decrease in the fair value of the AVH share call options, AVH share appreciation rights and AVH share-based upside sharing agreement.

Nonoperating special termination benefits and settlement losses. During the three and six months ended June 30, 2020, the Company recorded $231 million of settlement losses related to the Company's primary defined benefit pension plans covering certain U.S. non-pilot employees, and special termination benefits offered under voluntary leave programs to certain front-line U.S. based employees participating in the non-pilot defined benefit pension plan and postretirement medical programs.

Nonoperating credit loss on BRW Term Loan and related guarantee. During the six months ended June 30, 2020, the Company recorded a $697 million expected credit loss allowance for the BRW Term Loan and related guarantee. AVH is currently in bankruptcy. See Notes 6 and 7 of this report for additional information.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

Overview

United Airlines Holdings, Inc. (together with its consolidated subsidiaries, "UAL" or the "Company") is a holding company, and its principal, wholly-owned subsidiary is United Airlines, Inc. (together with its consolidated subsidiaries, "United"). This Quarterly Report on Form 10-Q is a combined report of UAL and United, including their respective consolidated financial statements. As UAL consolidates United for financial statement purposes, disclosures that relate to activities of United also apply to UAL, unless otherwise noted. United's operating revenues and operating expenses comprise nearly 100% of UAL's revenues and operating expenses. In addition, United comprises approximately the entire balance of UAL's assets, liabilities and operating cash flows. When appropriate, UAL and United are named specifically for their individual contractual obligations and related disclosures and any significant differences between the operations and results of UAL and United are separately disclosed and explained. We sometimes use the words "we," "our," "us," and the "Company" in this report for disclosures that relate to all of UAL and United.

The Company transports people and cargo through its mainline operations, which utilize jet aircraft with at least 126 seats, and regional operations, which utilize smaller aircraft that are operated under contract by United Express carriers. The Company serves virtually every major market around the world, either directly or through participation in Star Alliance®, the world's largest airline alliance.

Impact of the COVID-19 Pandemic and Outlook

The novel coronavirus (COVID-19) pandemic, together with the measures implemented or recommended by governmental authorities and private organizations in response to the pandemic, has had an adverse impact that has been material to the Company's business, operating results, financial condition and liquidity. The full extent of the ongoing impact of COVID-19 on the Company's longer-term operational and financial performance will depend on future developments, including those outside our control related to the efficacy and speed of vaccination programs in curbing the spread of the virus in different markets, the introduction and spread of new variants of the virus that may be resistant to currently approved vaccines and the continuation of existing or implementation of new government travel restrictions.

Capacity. The Company began experiencing a significant decline in international and domestic travel demand related to COVID-19 during the first quarter of 2020, and this reduction in demand has continued through the date of this report. However, since March 2021, the Company has seen increasing demand for travel both domestically and in countries where entry is permitted. The Company cut, relative to second quarter 2019 capacity, approximately 46% of its scheduled capacity for the second quarter of 2021 and expects its third quarter scheduled capacity to be down approximately 26% versus the third quarter of 2019. The Company will continue to monitor booking trends for future travel and adjust its capacity as needed.

Cost Reductions. The Company has identified over $2.0 billion of annual permanent structural cost reductions including improvements in labor efficiencies. During the first quarter of 2021, the Company offered voluntary leaves of absences to certain U.S.-based front-line employees. This program included (based on employee group, age and completed years of service) a partially-paid leave of absence with active health care coverage and travel privileges. Employees who separate from the Company after the end of such program receive certain separation benefits, such as post-employment health benefits and travel privileges. Approximately 4,500 employees elected to participate in this program, and it is expected that the majority of them will separate from employment at the end of their leave of absence. See Note 5 and Note 9 to the financial statements included in Part I, Item 1 of this report for additional information on charges related to these programs.

Liquidity. The Company entered into a number of transactions to improve its liquidity and manage its capital. In the first half of 2021, the Company:

•issued, through a private offering to eligible purchasers, $4.0 billion in aggregate principal amount of two series of notes, consisting of $2.0 billion in aggregate principal amount of 4.375% senior secured notes due 2026 (the "2026 Notes") and $2.0 billion in aggregate principal amount of 4.625% senior secured notes due 2029 (the "2029 Notes" and, together with the 2026 Notes, the "Notes," and each a "series" of Notes);

•entered into a new Term Loan Credit and Guaranty Agreement (the "New Term Loan Facility") initially providing term loans up to an aggregate amount of $5.0 billion and a new Revolving Credit and Guaranty Agreement (the "New Revolving Credit Facility" and, together with the New Term Loan Facility, the "New Loan Facilities") initially providing revolving loan commitments of up to $1.75 billion;

•repaid in full the $1.4 billion aggregate principal amount outstanding under the term loan facility (the "2017 Term Loan Facility") included in the Amended and Restated Credit and Guaranty Agreement, dated as of March 29, 2017 (the "Existing Credit Agreement");

29

•repaid in full the $1.0 billion aggregate principal amount outstanding under the revolving credit facility (the "2017 Revolving Credit Facility") included in the Existing Credit Agreement;

•repaid in full the $520 million aggregate principal amount outstanding under the Loan and Guarantee Agreement, dated as of September 28, 2020, among United, UAL, the U.S. Treasury Department ("Treasury") and the Bank of New York Mellon, as administrative agent, as amended (the "CARES Act Loan"), which was entered into pursuant to the loan program established pursuant to the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act");

•entered into approximately $0.6 billion in new enhanced equipment trust certificates ("EETC"); and

•raised approximately $0.5 billion in net cash proceeds from the issuance and sale of UAL common stock.

In addition to the foregoing transactions, United entered into the following agreements with Treasury:

PSP2. On January 15, 2021, United entered into a Payroll Support Program Extension Agreement (the "PSP2 Agreement") with Treasury providing the Company with total funding of approximately $3.0 billion, pursuant to the Payroll Support Program established under Subtitle A of Title IV of Division N of the Consolidated Appropriations Act, 2021. These funds were used to pay for the wages, salaries and benefits of United employees, including the payment of lost wages, salaries and benefits to returning employees. Approximately $2.1 billion was provided as a direct grant and $870 million as indebtedness evidenced by a 10-year senior unsecured promissory note (the "PSP2 Note"). See Note 2 to the financial statements included in Part I, Item 1 of this report for additional information on the warrants issued in connection with the PSP2 Note and Note 8 of this report for a discussion of the PSP2 Note. As a result of the PSP2 Agreement, the Company offered an opportunity to return to active employment to U.S. employees who were impacted by involuntary furloughs.

PSP3. On April 29, 2021, in connection with the Payroll Support Program established under Section 7301 of the American Rescue Plan Act of 2021, United entered into a Payroll Support Program 3 Agreement (the "PSP3 Agreement") with Treasury providing the Company with total funding of approximately $2.8 billion. Approximately $2.0 billion was provided as a direct grant and $810 million as indebtedness evidenced by a 10-year senior unsecured promissory note (the "PSP3 Note"). These funds will be used by United exclusively for the continuation of payment of its employee wages, salaries and benefits. See Note 2 to the financial statements included in Part I, Item 1 of this report for additional information on the warrants issued in connection with the PSP3 Note and Note 8 of this report for a discussion of the PSP3 Note.

United Next. On June 27, 2021, United entered into a supplemental agreement to that certain Purchase Agreement, dated May 15, 2018 with The Boeing Company ("Boeing") for a firm narrowbody aircraft order of 200 Boeing 737 MAX aircraft. The order consists of 150 Boeing 737 MAX 10s and 50 Boeing 737 MAX 8s. Also on June 27, 2021, United entered into an amendment to that certain Purchase Agreement, dated December 3, 2019 with Airbus S.A.S. ("Airbus") for a firm narrowbody aircraft order of 70 Airbus A321neo aircraft. The firm orders of 200 Boeing 737 MAX aircraft and 70 Airbus A321neo aircraft are expected to be delivered starting in 2023 through 2028 and 2026, respectively.

The "United Next" plan will have a transformational effect on the customer experience and is expected to increase the total number of available seats per domestic departure by almost 30% by 2026 and significantly lower carbon emissions per seat.

The new aircraft order will come with a new signature interior that includes seat-back entertainment in every seat, larger overhead bins for every passenger's carry-on bag and the industry's fastest available in-flight WiFi, as well as a bright look-and-feel with LED lighting. Adding these new 737 MAX and Airbus A321neo aircraft means the Company will replace older, smaller mainline jets and at least 200 single-class regional jets with larger aircraft, which we expect will lead to significant sustainability benefits compared to older planes: an expected 11% overall improvement in fuel efficiency and an expected 17-20% lower carbon emission per seat compared to older planes.

RESULTS OF OPERATIONS

The following discussion provides an analysis of our results of operations and reasons for material changes therein for the three months ended June 30, 2021 as compared to the corresponding period in 2020.

Passenger revenue increased $3.7 billion, or 541.1%, in the second quarter of 2021 as compared to the year-ago period, primarily due to improvements in demand for air travel as COVID-19 vaccinations are increasingly available in the United States and certain other jurisdictions and as more governments are lifting travel and quarantine restrictions.

Cargo revenue increased $204 million, or 50.7%, in the second quarter of 2021 as compared to the year-ago period, primarily due to an increase in cargo-only flights as a result of increased demand for critical goods during the COVID-19 pandemic and continued capacity growth across markets.

Other operating revenue increased $107 million, or 27.3%, in the second quarter of 2021 as compared to the year-ago period, primarily due to an increase in mileage revenue from non-airline partners, including the co-branded credit card partner, JPMorgan Chase Bank, N.A.

Salaries and related costs increased $106 million, or 4.9%, in the second quarter of 2021 as compared to the year-ago period, despite the 8.1% decrease in headcount, primarily due to several factors including an increase in front-line employees' salaries from higher flight capacity, prior year schedule reductions for management and administrative employees, prior year Company offered leaves of absence by front-line employees and $34 million in lower tax credits provided by the Employee Retention Credit under the CARES Act.

Aircraft fuel expense increased by $992 million, or 413.3%, in the second quarter of 2021 as compared to the year-ago period, due to both higher average price per gallon and increased consumption. The table below presents the significant changes in

32

Landing fees and other rent increased $135 million, or 31.5%, in the second quarter of 2021 as compared to the year-ago period, primarily due to an increase in capacity-based rent and landing fees.

Regional capacity purchase increased $159 million, or 41.0%, in the second quarter of 2021 as compared to the year-ago period, primarily due to increased regional flying and increased pass-through maintenance costs.

Aircraft maintenance materials and outside repairs increased $192 million, or 174.5%, in the second quarter of 2021 as compared to the year-ago period, primarily due to higher volumes of flying and the timing of airframe maintenance events.

Distribution expenses increased $108 million, or 348.4%, in the second quarter of 2021 as compared to the year-ago period, primarily due to higher credit card fees, commissions and higher volume of global distribution fees as a result of the overall increase in passenger revenue.

Details of the Company's special charges (credits) include the following for the three months ended June 30 (in millions):

	2021		2020

Interest expense increased $230 million, or 117.3%, in the second quarter of 2021 as compared to the year-ago period, primarily due to the issuance of new debt to provide additional liquidity to the Company during the COVID-19 pandemic.

Unrealized gains on investments, net, was $147 million in the second quarter of 2021 as compared to $9 million in the year-ago period, primarily due to the change in the market value of the Company's equity investment in Azul Linhas Aéreas Brasileiras S.A. ("Azul") and Clear Secure, Inc. (formerly Alclear, Inc.) ("Clear"). See Note 6 to the financial statements included in Part I, Item 1 of this report for information related to these equity investments.

Miscellaneous, net decreased $158 million in the second quarter of 2021 as compared to the year-ago period, primarily due to $231 million of special termination benefits and settlement losses related to voluntary separation programs under the Company's postretirement medical programs and defined benefit plans recorded in the second quarter of 2020. See Notes 5, 6, 7 and 9 to the financial statements included in Part I, Item 1 of this report for additional information.

Passenger revenue in the first six months of 2021 decreased $1.1 billion, or 13.7%, as compared to the year-ago period, primarily due to the impacts of the worldwide spread of COVID-19 and travel restrictions that started in the latter part of the first quarter of 2020.

Cargo revenue increased $437 million, or 65.6%, in the first six months of 2021 as compared to the year-ago period, primarily due to an increase in cargo-only flights as a result of increased demand for critical goods during the COVID-19 pandemic. With long haul passenger demand now increasing we will cease most cargo-only flights for the remainder of 2021 although we continue to project strong cargo yields for the remainder of the year.

Other operating revenue decreased $135 million, or 13.0%, in the first six months of 2021 as compared to the year-ago period, primarily due to lower passenger volumes, lower United Club lounge usage, and a decline in mileage revenue from non-airline partners, including the co-branded credit card partner, JPMorgan Chase Bank, N.A.

Operating Expenses. The table below includes data related to the Company's operating expenses for the six months ended June 30 (in millions, except for percentage changes):

Total operating expenses	$	10,343	$	12,063	$	(1,720)	(14.3)

Salaries and related costs decreased $625 million, or 12.2%, in the first six months of 2021 as compared to the year-ago period, primarily due to lower headcount as a result of various employee voluntary separation programs since the start of the COVID-19 pandemic and a $206 million increase in tax credits provided by the Employee Retention Credit under the CARES Act.

Aircraft fuel expense increased $117 million, or 6.0%, in the first six months of 2021 as compared to the year-ago period, primarily due to the higher average price per gallon of fuel. The table below presents the significant changes in aircraft fuel cost

35

per gallon in the six months ended June 30, 2021 as compared to the year-ago period:

	(In millions)						Average price per gallon
	2021		2020		% Change		2021		2020		% Change
Fuel expense	$	2,083	$	1,966	6.0	%	$	1.87	$	1.76	6.3	%
Fuel consumption (gallons)	1,115		1,114		0.1	%

Regional capacity purchase decreased $99 million, or 8.8%, in the first six months of 2021 as compared to the year-ago period, primarily due to reduced regional flying in the first half of 2021 as a result of COVID-19 compared to the first half of 2020 which did not experience significantly reduced flying until March of that time period.

Distribution expenses decreased $102 million, or 31.3%, in the first six months of 2021 as compared to the year-ago period, primarily due to lower credit card fees, commissions and lower volume of global distribution fees as a result of the overall decrease in passenger revenue due to the COVID-19 pandemic.

Details of the Company's special charges (credits) include the following for the six months ended June 30 (in millions):

	2021		2020
CARES Act grant	$	(2,889)	$	(1,589)
Impairment of assets	59		130
Severance and benefit costs	428		63

Special charges (credits)	$	(2,325)	$	(1,386)

See Note 9 to the financial statements included in Part I, Item 1 of this report for additional information on the Company's special charges (credits).

Other operating expenses decreased $150 million, or 7.6%, in the first six months of 2021 as compared to the year-ago period, primarily due to the impacts of COVID-19 on our catering and crew-related expenses, as well as lower advertising and other discretionary spend.

Nonoperating Income (Expense). The following table illustrates the year-over-year dollar and percentage changes in the Company's nonoperating income (expense) for the six months ended June 30 (in millions, except for percentage changes):

	2021		2020		Increase (Decrease)		% Change
Interest expense	$	(779)	$	(367)	$	412	112.3
Interest capitalized	39		38		1		2.6
Interest income	19		37		(18)		(48.6)
Unrealized gains (losses) on investments, net	125		(310)		435		NM
Miscellaneous, net	(68)		(906)		(838)		(92.5)
Total	$	(664)	$	(1,508)	$	(844)	(56.0)

Interest expense increased $412 million, or 112.3%, in the first six months of 2021 as compared to the year-ago period, primarily due to the issuance of new debt to provide additional liquidity to the Company during the COVID-19 pandemic.

Unrealized gains on investments, net, was $125 million in the first six months of 2021 as compared to $310 million in unrealized losses in the year-ago period, primarily due to the change in the market value of the Company's equity investment in Azul. See Note 6 to the financial statements included in Part I, Item 1 of this report for information related to this equity investment.

Miscellaneous, net decreased $838 million in the first six months of 2021 as compared to the year-ago period, primarily due to the $697 million of credit loss allowances associated with the Company's Term Loan Agreement, with, among others, BRW Aviation Holding LLC and BRW Aviation LLC, and the related guarantee recorded in the first quarter of 2020, and lower special termination benefits related to voluntary separation programs under the Company's non-pilot U.S. defined benefit pension plan and postretirement medical programs. See Notes 5, 6, 7 and 9 to the financial statements included in Part I, Item 1 of this report for additional information.

Income Taxes. See Note 4 to the financial statements included in Part I, Item 1 of this report for information related to income taxes.

LIQUIDITY AND CAPITAL RESOURCES

Current Liquidity

As of June 30, 2021, the Company had $21.1 billion in unrestricted cash, cash equivalents and short-term investments, as compared to $11.7 billion at December 31, 2020. As of June 30, 2021, the Company also had $1.75 billion available for borrowing under the New Revolving Credit Facility at any time until April 21, 2025.

The Company has taken a number of actions in response to the significant decline in international and domestic demand for air travel related to the COVID-19 pandemic, as discussed under "Impact of the COVID-19 Pandemic and Outlook" above. The Company continues to focus on reducing expenses and managing its liquidity but has also begun preparing for an eventual recovery from the COVID-19 pandemic. Since March 2021, we have seen increasing demand for travel both domestically and in countries where entry is permitted, and we are taking steps, which include making certain investments in the recovery, to be prepared if demand for travel continues to increase in line with recent customer booking trends. However, the timing of demand recovery will be dependent on a number of factors outside of our control, and we expect to continue to modify our cost management structure and capacity as the timing of demand recovery becomes more certain.

On January 15, 2021, United entered into the PSP2 Agreement with Treasury, providing the Company with total funding of approximately $3.0 billion, consisting of approximately $2.1 billion as a direct grant and $870 million as indebtedness evidenced by the PSP2 Note. See Note 8 to the financial statements included in Part I, Item 1 of this report for a discussion of the PSP2 Note.

On April 29, 2021, United entered into a PSP3 Agreement with Treasury, providing the Company with total funding of approximately $2.8 billion, consisting of approximately $2.0 billion as a direct grant and $810 million as indebtedness evidenced by the PSP3 Note. See Note 8 to the financial statements included in Part I, Item 1 of this report for a discussion of the PSP3 Note.

Several of the Company's debt agreements contain covenants that, among other things, restrict the ability of the Company and its subsidiaries to incur additional indebtedness and pay dividends or repurchase stock. As of June 30, 2021, UAL and United were in compliance with their respective debt covenants.

We have a significant amount of fixed obligations, including debt, leases of aircraft, airport and other facilities, and pension funding obligations. As of June 30, 2021, the Company had approximately $41.8 billion of debt, finance lease, operating lease and sale-leaseback obligations, including $2.6 billion that will become due in the next 12 months. In addition, we have substantial noncancelable commitments for capital expenditures, including the acquisition of certain new aircraft and related spare engines.

As of June 30, 2021, United had firm commitments and options to purchase aircraft from Boeing and Airbus as presented in the table below:

		Scheduled Aircraft Deliveries
Aircraft Type	Number of Firm  Commitments (a)	Last Six Months of 2021	2022	2023	After 2022
Airbus A321XLR	50	—	—	—	50
Airbus A321neo	70	—	—	16	54
Airbus A350	45	—	—	—	45
Boeing 737 MAX	380	13	40	122	205
Boeing 787	8	8	—	—	—
(a) United also has options and purchase rights for additional aircraft.

The aircraft listed in the table above are scheduled for delivery through 2030. To the extent the Company and the aircraft manufacturers with whom the Company has existing orders for new aircraft agree to modify the contracts governing those orders, or to the extent rights are exercised pursuant to the relevant agreements to modify the timing of deliveries, the amount and timing of the Company's future capital commitments could change.

37

United also has an agreement to purchase six used Boeing 737-700 aircraft, which it intends to sell, with expected delivery dates in 2021. In addition, United has an agreement to purchase 11 used Airbus A319 aircraft, which it intends to sell, with expected delivery dates in 2021 and 2022.

In 2020, United entered into agreements with third parties to finance through sale and leaseback transactions new Boeing model 787 aircraft and Boeing model 737 MAX aircraft subject to purchase agreements between United and Boeing. In connection with the delivery of each aircraft from Boeing, United assigned its right to purchase such aircraft to the buyer, and simultaneous with the buyer's purchase from Boeing, United entered into a long-term lease for such aircraft with the buyer as lessor. Eleven Boeing model aircraft were delivered in 2021 under these transactions (and each is presently subject to a long-term lease to United). Remaining aircraft in the agreements are scheduled to be delivered in the last six months of 2021.

As of June 30, 2021, UAL and United have total capital commitments related to the acquisition of aircraft and related spare engines, aircraft improvements and non-aircraft capital commitments for approximately $35.3 billion, of which approximately $3.1 billion, $3.4 billion, $7.4 billion, $4.7 billion, $4.3 billion and $12.4 billion are due in the last six months of 2021 and for the full years 2022, 2023, 2024, 2025 and thereafter, respectively. To the extent the Company and Boeing agree to modify the timing of Boeing 737 MAX deliveries, the amount and timing of the Company's future capital commitments could change.

We expect that our 2021 liquidity needs will be met through our existing liquidity levels. While we have been able to access the capital markets to meet our significant long-term debt and finance lease obligations and future commitments for capital expenditures, including the acquisition of aircraft and related spare engines, we must return to profitability in order to service our debt and maintain appropriate liquidity levels for our long-term operating needs. We may also pursue financing options for our firm order aircraft and other related capital expenditures consistent with our historical practice prior to the onset of the COVID-19 pandemic. The Company has backstop financing commitments available from certain of its aircraft manufacturers for a limited number of its future aircraft deliveries, subject to certain customary conditions.

See Note 8 to the financial statements included in Part I, Item 1 of this report for additional information on aircraft financing and other debt instruments.

As of June 30, 2021, a substantial portion of the Company's assets, principally aircraft and certain related assets, its loyalty program, certain route authorities and airport slots, was pledged under various loan and other agreements. As of April 21, 2021, the Company pledged as collateral for the Notes and the New Loan Facilities the following: (i) all of United's route authorities granted by the U.S. Department of Transportation to operate scheduled service between any international airport located in the United States and any international airport located in any country other than the United States (except Cuba), (ii) United's rights to substantially all of its landing and take-off slots at foreign and domestic airports, including at John F. Kennedy International Airport, LaGuardia Airport and Ronald Reagan Washington National Airport (subject to certain exclusions), and (iii) United's rights to use or occupy space at airport terminals, each to the extent necessary at the relevant time for servicing scheduled air carrier service authorized by an applicable route authority.

Credit Ratings. As of the filing date of this report, UAL and United had the following corporate credit ratings:

	S&P	Moody's	Fitch
UAL	B+	Ba2	B+
United	B+	*	B+
* The credit agency does not issue corporate credit ratings for subsidiary entities.

These credit ratings are below investment grade levels; however, the Company has been able to secure financing with investment grade credit ratings for certain enhanced equipment trust certificates ("EETCs"), term loans and secured bond financings. Downgrades from current rating levels, among other things, could restrict the availability and/or increase the cost of future financing for the Company.

Sources and Uses of Cash

Operating Activities. Cash flows provided by operations were $3.1 billion for the six months ended June 30, 2021 compared to cash flows used in operations of $67 million for the same period in 2020. The increase is primarily attributable to improvements in the demand for passenger travel as well as government grant funding provided under the PSP2 Agreement and PSP3 Agreement of $4.1 billion partially offset by continuing operating losses as a result of the COVID-19 pandemic.

Investing Activities. Capital expenditures were approximately $1.3 billion and $2.0 billion in the six months ended June 30, 2021 and 2020, respectively. Capital expenditures for the six months ended June 30, 2021 were primarily attributable to advance deposits for future aircraft purchases.

38

Financing Activities. Significant financing events in the six months ended June 30, 2021 were as follows:

Debt, Finance Lease and Other Financing Liability Principal Payments. During the six months ended June 30, 2021, the Company made payments for debt, finance leases and other financing liabilities of $4.1 billion, primarily for repayments of $1.4 billion aggregate principal amount outstanding under the 2017 Term Loan Facility, $1.0 billion aggregate principal amount outstanding under the 2017 Revolving Credit Facility and $520 million aggregate principal amount outstanding under the CARES Act Loan.

Debt Issuances. During the six months ended June 30, 2021, United received and recorded:

•$870 million from the PSP2 Note;

•$600 million of proceeds as debt from the EETC pass-through trusts established in February 2021;

•$810 million from the PSP3 Note;

•$5.0 billion from the New Term Loan Facility; and

•$4.0 billion from the 2026 Notes and 2029 Notes.

See Note 8 to the financial statements included in Part I, Item 1 of this report for additional information.

Share Issuance. During the six months ended June 30, 2021, the Company raised approximately $532 million in net cash proceeds from the issuance and sale of UAL common stock through "at the market offerings" under equity distribution agreements entered into in June 2020 and March 2021. During the quarter ended June 30, 2021, approximately 8,300 shares were sold through "at the market offerings" under such equity distribution agreements at an average price of $55.13 per share, with net proceeds to the Company totaling approximately $0.5 million.

Commitments, Contingencies and Liquidity Matters. As described in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2020 (the "2020 Form 10-K"), the Company's liquidity may be adversely impacted by a variety of factors, including, but not limited to, pension funding obligations, reserve requirements associated with credit card processing agreements, guarantees, commitments, contingencies and the ongoing impact of the COVID-19 pandemic.

See the 2020 Form 10-K and Notes 5, 6, 7, 8 and 9 to the financial statements contained in Part I, Item 1 of this report for additional information.

Risk Factor Summary

The following is a summary of the principal risks that could adversely affect, or have adversely affected, the Company's business, operating results and financial condition:

•The adverse impacts of the ongoing COVID-19 global pandemic, and possible outbreaks of another disease or similar public health threat in the future, on our business, operating results, financial condition, liquidity and near-term and long-term strategic operating plan, including possible additional adverse impacts resulting from the duration and spread of the pandemic;

Risks Relating to COVID-19

The global pandemic resulting from a novel strain of coronavirus has had an adverse impact that has been material to the Company's business, operating results, financial condition and liquidity, and the duration and spread of the pandemic could result in additional adverse impacts. The outbreak of another disease or similar public health threat in the future could also have an adverse effect on the Company's business, operating results, financial condition and liquidity.

The novel coronavirus (COVID-19) pandemic, together with the measures implemented or recommended by governmental authorities and private organizations in response to the pandemic, has had an adverse impact that has been material to the Company's business, operating results, financial condition and liquidity. Measures such as "shelter in place" or quarantine requirements, international and domestic travel restrictions or advisories, limitations on public gatherings, social distancing recommendations, remote work arrangements and closures of tourist destinations and attractions, as well as consumer perceptions of the safety, ease and predictability of air travel, contributed to a precipitous decline in passenger demand and bookings for both business and leisure travel.

The Company began experiencing a significant decline in international and domestic demand related to COVID-19 during the first quarter of 2020. The decline in demand caused a material deterioration in our revenues in 2020, resulting in a net loss of $7.1 billion. The full extent of the ongoing impact of COVID-19 on the Company's longer-term operational and financial performance will depend on future developments, including those outside our control related to the efficacy and speed of vaccination programs in curbing the spread of the virus in different markets, the introduction and spread of new variants of the virus that may be resistant to currently approved vaccines, passenger testing requirements, mask mandates or other restrictions on travel, all of which are highly uncertain and cannot be predicted with certainty. In response to decreased demand, the Company cut, relative to 2019 capacity, approximately 57% of its scheduled capacity for 2020. In the second quarter of 2021, scheduled capacity was down approximately 46% versus the second quarter of 2019. However, since March 2021, the Company has seen increasing demand for travel both domestically and in countries where entry is permitted. The Company currently expects scheduled capacity for the third quarter of 2021 to be down 26% compared to the third quarter of 2019. However, as noted above, the full extent of the ongoing impact of COVID-19 on the Company's longer-term operational and

43

financial performance will depend on future developments, including vaccination programs, new variants of the virus and government-imposed travel restrictions. As such, the Company's actual flown capacity may differ materially from its currently scheduled capacity.

The Company has taken a number of actions in response to the decreased demand for air travel, including those described in Part I. Item 2, Management's Discussion and Analysis of Financial Condition and Results of Operations, of this report and in Part II, Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations, of the 2020 Form 10-K. The grants and loans under the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act"), as extended, subject the Company and its business to certain restrictions, including, but not limited to, restrictions on the payment of dividends and the ability to repurchase UAL's equity securities; requirements to maintain certain levels of scheduled service, requirements to recall certain furloughed employees and maintain U.S. employment levels through September 30, 2021 or the date on which the Company has expended all of the support, whichever is later and certain limitations on executive compensation. These restrictions and requirements have materially affected and will continue to materially affect the Company's operations, and the Company may not be successful in managing these impacts for the duration of the restrictions. In particular, limitations on executive compensation may impact the Company's ability to attract and retain senior management or attract other key employees during this critical time.

The full extent of the ongoing impact of COVID-19 on the Company's longer-term operational and financial performance and liquidity position will depend on future developments, including the effectiveness of the mitigation strategies discussed above in offsetting decreased demand so long as demand remains suppressed, the duration and spread of COVID-19 in different markets and related governmental actions, the impact of COVID-19 on overall long-term domestic and international demand for air travel, including the impact on overall demand for business travel as a result of increased usage of teleconferencing and other technologies, and the impact of COVID-19 on the financial health and operations of the Company's business partners. All of these future developments are highly uncertain and cannot be predicted with certainty. The COVID-19 pandemic has had a material impact on the Company, and the continuation of reduced demand could have a material adverse effect on the Company's business, operating results, financial condition and liquidity.

In addition, an outbreak of another disease or similar public health threat, or fear of such an event, that affects travel demand, travel behavior or travel restrictions could have a material adverse impact on the Company's business, financial condition and operating results. Outbreaks of other diseases could also result in increased government restrictions and regulation, such as those actions described above or otherwise, which could adversely affect our operations.

COVID-19 materially disrupted our strategic operating plans in the near-term, and there are risks to our business, operating results and financial condition associated with adjusting and executing our strategic operating plans in the long-term.

COVID-19 materially disrupted our strategic operating plans in the near-term, and there are risks to our business, operating results and financial condition associated with adjusting and executing our strategic operating plans in the long-term. In recent years, we have announced several strategic operating plans, including several revenue-generating initiatives and plans to optimize our revenue, such as our plans to add capacity, including international expansion and new or increased service to mid-size airports, initiatives and plans to optimize and control our costs and opportunities to enhance our segmentation and improve the customer experience at all points in air travel. In the second quarter of 2021, we announced the "United Next" plan, including firm orders of 200 Boeing 737 MAX aircraft and 70 Airbus A321neo aircraft, plans to retrofit the remaining mainline, narrow-body fleet to transform the customer experience and create a new signature interior and plans to increase the number of mainline daily departures and available seats across our North American network. In developing our strategic operating plans, we make certain assumptions, including, but not limited to, those related to customer demand, competition, market consolidation, the availability of aircraft and the global economy. Actual economic, market and other conditions have been and may continue to be different from our assumptions. Most significantly in 2020, the precipitous decline in demand for air travel required us to cut, rather than grow, capacity, and materially and adversely impacted our ability to execute our strategic operating plans. We have since adjusted our strategic operating plans based on our expectations for increased customer demand with the "United Next" plan. If we do not successfully execute or adjust our strategic operating plans in the long-term, or if actual results continue to vary significantly from our assumptions, our business, operating results and financial condition could be materially and adversely impacted.

Risks Relating to Our Business and Industry

Unfavorable economic and political conditions, in the United States and globally, may have a material adverse effect on our business, operating results and financial condition.

The Company's business and operating results are significantly impacted by U.S. and global economic and political conditions. The airline industry is highly cyclical, and the level of demand for air travel is correlated to the strength of the U.S.

44

and global economies. Robust demand for the Company's air transportation services depends largely on favorable economic conditions, including the strength of the domestic and foreign economies, low unemployment levels, strong consumer confidence levels and the availability of consumer and business credit. Air transportation is often a discretionary purchase that leisure travelers may limit or eliminate during difficult economic times. Short-haul travelers, in particular, have the option to replace air travel with surface travel. In addition, during periods of unfavorable economic conditions, business travelers historically have reduced the volume of their travel, either due to cost-saving initiatives, the replacement of travel with alternatives such as videoconferencing, or as a result of decreased business activity requiring travel. During such periods, the Company's business and operating results may be adversely affected due to significant declines in industry passenger demand, particularly with respect to the Company's business and premium cabin travelers, and a reduction in fare levels.

As a global business with operations outside of the United States from which it derives significant operating revenues, volatile conditions in certain international regions may have a negative impact on the Company's operating results and its ability to achieve its business objectives. The Company's international operations are a vital part of its worldwide airline network. Political disruptions and instability in certain regions can negatively impact the demand and network availability for air travel. Additionally, any deterioration in global trade relations, such as increased tariffs or other trade barriers, could result in a decrease in the demand for international air travel.

Stagnant or weakening global economic conditions either in the United States or in other geographic regions may have a material adverse effect on the Company's revenues, operating results and liquidity.

The global airline industry is highly competitive and susceptible to price discounting and changes in capacity, which could have a material adverse effect on our business, operating results and financial condition.

The airline industry is highly competitive, marked by significant competition with respect to routes, fares, schedules (both timing and frequency), services, products, customer service and frequent flyer programs. Consolidation in the airline industry, the rise of well-funded government sponsored international carriers, changes in international alliances and the creation of immunized joint business arrangements ("JBAs") have altered and are expected to continue to alter the competitive landscape in the industry, resulting in the formation of airlines and alliances with increased financial resources, more extensive global networks and services and competitive cost structures.

Airlines also compete by increasing or decreasing their capacity, including route systems and the number of destinations served. Several of the Company's domestic and international competitors have increased their international capacity by including service to some destinations that the Company currently serves, causing overlap in destinations served, and therefore, increasing competition for those destinations. This increased competition in both domestic and international markets may have a material adverse effect on the Company's business, operating results and financial condition.

The Company's U.S. operations are subject to competition from traditional network carriers, national point-to-point carriers, and discount carriers, including low-cost carriers and ultra-low-cost carriers. Such carriers may have lower costs and provide service at lower fares to destinations also served by the Company. The significant presence of low-cost carriers and ultra-low-cost carriers, which engage in substantial price discounting, may diminish our ability to achieve sustained profitability on domestic and international routes. This level of discounted pricing has also caused us to reduce fares for certain routes, resulting in lower yields on many domestic markets. Our ability to compete in the domestic market effectively depends, in part, on our ability to maintain a competitive cost structure. If we cannot maintain our costs at a competitive level, then our business, operating results and financial condition could continue to be materially and adversely affected. In addition, our competitors have established new routes and destinations, including some at our hub airports, in light of the expansion opportunities presented by the COVID-19 pandemic, which may compete with our existing routes and destinations and expansion plans.

Our international operations are subject to competition from both foreign and domestic carriers. Competition is significant from government subsidized competitors from certain Middle East countries. These carriers have large numbers of international widebody aircraft on order and are increasing service to the U.S. from their hubs in the Middle East. The government support provided to these carriers has allowed them to grow quickly, reinvest in their product, invest in other airlines and expand their global presence. We also face competition from foreign carriers operating under "fifth freedom" rights permitted under international treaties that allow certain carriers to provide service to and from stopover points between their home country and ultimate destination, including points in the United States, in competition with service provided by us.

Through alliance and other marketing and codesharing agreements with foreign carriers, U.S. carriers have increased their ability to sell international transportation, such as services to and beyond traditional global gateway cities. Similarly, foreign carriers have obtained increased access to interior U.S. passenger traffic beyond traditional U.S. gateway cities through these relationships. In addition, several JBAs among U.S. and foreign carriers have received grants of antitrust immunity allowing the participating carriers to coordinate schedules, pricing, sales and inventory. If we are not able to continue

45

participating in these types of alliance and other marketing and codesharing agreements in the future, our business, operating results and financial condition could be materially and adversely affected.

Our MileagePlus frequent flyer program benefits from the attractiveness and competitiveness of United Airlines as a material purchaser of award miles, and the majority recipient for mileage redemption. If we are not able to maintain a competitive and attractive airline business, our ability to acquire, engage and retain customers in the loyalty program may be adversely affected, which could adversely affect the loyalty program's operating results and financial condition.

Further our MileagePlus frequent flyer program also faces significant and increasing direct competition from the frequent flyer programs offered by other airlines, as well as from similar loyalty programs offered by banks and other financial services companies. Competition among loyalty programs is intense regarding customer acquisition incentives, the value and utility of program currency, rewards range and value, fees, required usage, and other terms and conditions of these programs. If we are not able to maintain a competitive frequent flyer program, our ability to attract and retain customers to MileagePlus and United alike may be adversely affected, which could adversely affect our enterprise operating results and financial condition.

High and/or volatile fuel prices or significant disruptions in the supply of aircraft fuel could have a material adverse impact on the Company's strategic plans, operating results, financial condition and liquidity.

Aircraft fuel is critical to the Company's operations and is one of our largest operating expenses. During the year ended December 31, 2020, the Company's fuel expense was approximately $3.2 billion. The timely and adequate supply of fuel to meet operational demand depends on the continued availability of reliable fuel supply sources, as well as related service and delivery infrastructure. Although the Company has some ability to cover short-term fuel supply and infrastructure disruptions at some major demand locations, it depends significantly on the continued performance of its vendors and service providers to maintain supply integrity. Consequently, the Company can neither predict nor guarantee the continued timely availability of aircraft fuel throughout the Company's system.

Aircraft fuel has historically been the Company's most volatile operating expense due to the highly unpredictable nature of market prices for fuel. The Company generally sources fuel at prevailing market prices. Market prices for aircraft fuel have historically fluctuated substantially in short periods of time and continue to be highly volatile due to a dependence on a multitude of unpredictable factors beyond the Company's control. These factors include changes in global crude oil prices, the balance between aircraft fuel supply and demand, natural disasters, prevailing inventory levels and fuel production and transportation infrastructure. Prices of fuel are also impacted by indirect factors, such as geopolitical events, economic growth indicators, fiscal/monetary policies, fuel tax policies, changes in regulations, environmental concerns and financial investments in energy markets. Both actual changes in these factors, as well as changes in related market expectations, can potentially drive rapid changes in fuel prices in short periods of time.

Given the highly competitive nature of the airline industry, the Company may not be able to increase its fares and fees sufficiently to offset the full impact of increases in fuel prices, especially if these increases are significant, rapid and sustained. Further, any such fare or fee increase may not be sustainable, may reduce the general demand for air travel and may also eventually impact the Company's strategic growth and investment plans for the future. In addition, decreases in fuel prices for an extended period of time may result in increased industry capacity, increased competitive actions for market share and lower fares or surcharges. If fuel prices were to then subsequently rise quickly, there may be a lag between the rise in fuel prices and any improvement of the revenue environment.

To protect against increases in the market prices of fuel, the Company may hedge a portion of its future fuel requirements. The Company does not currently hedge its future fuel requirements. However, to the extent the Company decides to start a hedging program, such hedging program may not be successful in mitigating higher fuel costs, and any price protection provided may be limited due to the choice of hedging instruments and market conditions, including breakdown of correlation between hedging instrument and market price of aircraft fuel and failure of hedge counterparties. To the extent that the Company decides to hedge a portion of its future fuel requirements and uses hedge contracts that have the potential to create an obligation to pay upon settlement if fuel prices decline significantly, such hedge contracts may limit the Company's ability to benefit fully from lower fuel prices in the future. If fuel prices decline significantly from the levels existing at the time the Company enters into a hedge contract, the Company may be required to post collateral (margin) beyond certain thresholds. There can be no assurance that the Company's hedging arrangements, if any, will provide any particular level of protection against rises in fuel prices or that its counterparties will be able to perform under the Company's hedging arrangements. Additionally, deterioration in the Company's financial condition could negatively affect its ability to enter into new hedge contracts in the future.

The Company relies heavily on technology and automated systems to operate its business and any significant failure or disruption of, or failure to effectively integrate and implement, the technology or these systems could materially harm its business.

46

The Company depends on automated systems and technology to operate its business, including, but not limited to, computerized airline reservation systems, electronic tickets, electronic airport kiosks, demand prediction software, flight operations systems, in-flight wireless internet, cloud-based technologies, revenue management systems, accounting systems, technical and business operations systems, telecommunication systems and commercial websites and applications, including www.united.com and the United Airlines app. United's website and other automated systems must be able to accommodate a high volume of traffic, maintain secure information and deliver important flight and schedule information, as well as process critical financial transactions. These systems could suffer substantial or repeated disruptions due to various events, some of which are beyond the Company's control, including natural disasters, power failures, terrorist attacks, equipment or software failures, cybersecurity attacks or other security breaches. We have initiatives in place to prevent disruptions and disaster recovery plans, and we continue to invest in improvements to these initiatives and plans; however, these measures may not be adequate to prevent or mitigate disruptions. Substantial or repeated systems failures or disruptions, including failures or disruptions related to the Company's complex integration of systems, could reduce the attractiveness of the Company's services versus those of our competitors, materially impair our ability to market our services and operate our flights, result in the unauthorized release of confidential or otherwise protected information, negatively impact our reputation among our customers and the public, subject us to liability to third parties, regulatory action or contract termination, result in other increased costs, lost revenue and the loss or compromise of important data. As a result, substantial or repeated systems failures or disruptions may adversely affect the Company's business, operating results and financial condition.

The Company may also face challenges in integrating, implementing and modifying the automated systems and technology required to operate its business. As a result of the complexity of such automated systems and technology, the integration, implementation and modification process may require significant expenditures, human resources, the development of effective internal controls and the transformation of business and financial processes. If the Company is unable to timely or effectively integrate, implement or modify its systems and technology, the Company's operations could be adversely affected.

The Company's business relies extensively on third-party service providers, including certain technology providers. Failure of these parties to perform as expected, or interruptions in the Company's relationships with these providers or their provision of services to the Company, could have a material adverse effect on the Company's business, operating results and financial condition.

The Company has engaged third-party service providers to perform a large number of functions that are integral to its business, including regional operations, operation of customer service call centers, distribution and sale of airline seat inventory, provision of information technology infrastructure and services, transmitting or uploading of data, provision of aircraft maintenance and repairs, provision of various utilities and performance of airport ground services, aircraft fueling operations and catering services, among other vital functions and services. The Company does not directly control these third-party service providers, although generally it does enter into agreements that define expected service performance and compliance requirements, such as compliance with legal requirements, including anti-corruption laws; however, there can be no assurance that our third-party service providers will adhere to these requirements.

Any of these third-party service providers, however, may materially fail to meet its service performance commitments to the Company or may suffer disruptions to its systems that could impact its services. For example, failures in certain third-party technology or communications systems may cause flight delays or cancellations. The failure of any of the Company's third-party service providers to perform its service obligations adequately, or other interruptions of services, may reduce the Company's revenues and increase its expenses, prevent the Company from operating its flights and providing other services to its customers or result in adverse publicity or harm to our brand. We may also be subject to consequences from any illegal conduct of our third-party service providers, including for their failure to comply with anti-corruption laws, such as the U.S. Foreign Corrupt Practices Act. In addition, the Company's business and financial performance could be materially harmed if its customers believe that its services are unreliable or unsatisfactory.

The Company may also have disagreements with such providers or such contracts may be terminated or may not be extended or renewed. For example, the number of flight reservations booked through third-party GDSs or online travel agents ("OTAs") may be adversely affected by disruptions in the business relationships between the Company and these suppliers. Such disruptions, including a failure to agree upon acceptable contract terms when contracts expire or otherwise become subject to renegotiation, may cause the Company's flight information to be limited or unavailable for display by the affected GDS or OTA operator, significantly increase fees for both the Company and GDS/OTA users and impair the Company's relationships with its customers and travel agencies. Any such disruptions or contract terminations may adversely impact our operations and financial results.

If we are not able to negotiate or renew agreements with third-party service providers, or if we renew existing agreements on less favorable terms, our operations and financial results may be adversely affected.

47

The Company could experience adverse publicity, harm to its brand, reduced travel demand, potential tort liability and voluntary or mandatory operational restrictions as a result of an accident, catastrophe or incident involving its aircraft or its operations, the aircraft or operations of its regional carriers, the aircraft or operations of its codeshare partners, or the aircraft or operations of another airline, which may result in a material adverse effect on the Company's business, operating results and financial condition.

An accident, catastrophe or incident involving an aircraft that the Company operates, or an aircraft that is operated by a codeshare partner, one of the Company's regional carriers or another airline, or an incident involving the Company's operations, or the operations of a codeshare partner, Original Equipment Manufacturers, one of the Company's regional carriers or of another airline, could have a material adverse effect on the Company if such accident, catastrophe or incident created a public perception that the Company's operations, or the operations of its codeshare partners or regional carriers, are not safe or reliable, or are less safe or reliable than other airlines. Additionally, any accident, catastrophe or incident involving an aircraft type that is operated by the Company, its codeshare partners or regional carriers could have a material adverse effect on the Company if such accident, catastrophe or incident creates a public perception that such aircraft type was not safe or reliable. Further, any such accident, catastrophe or incident involving the Company, its regional carriers or its codeshare partners could expose the Company to significant tort liability. Although the Company currently maintains liability insurance in amounts and of the type the Company believes to be consistent with industry practice to cover damages arising from any such accident, catastrophe or incident, and the Company's codeshare partners and regional carriers carry similar insurance and generally indemnify the Company for their operations, if the Company's liability exceeds the applicable policy limits or the ability of another carrier to indemnify it, the Company could incur substantial losses from an accident, catastrophe or incident which may result in a material adverse effect on the Company's operating results and financial condition. In addition, any such accident, catastrophe or incident involving the Company, its regional carriers or its codeshare partners could result in operational restrictions on the Company, including voluntary or mandatory groundings of aircraft. For example, the Company decided to voluntarily ground its Boeing 737 aircraft following certain electrical issues, and in February 2021, the FAA issued an Emergency Airworthiness Directive regarding certain Boeing 777 Pratt & Whitney powered aircraft. The resulting public perceptions of the safety of our operations and the reliability of certain Boeing 777 Pratt & Whitney powered aircraft and Boeing 737 aircraft, including the new Boeing 737 MAX 8 aircraft and Boeing 737 MAX 10 aircraft that the Company ordered in the second quarter of 2021, could adversely affect our business. A prolonged period of time operating a reduced fleet in these circumstances could result in a material adverse effect on the Company's operating results and financial condition.

In addition, the outbreak and spread of the COVID-19 pandemic have adversely impacted customer perceptions of the health and safety of travel and these negative perceptions could continue even after the pandemic subsides. Actual or perceived risk of infection on our flights, at airports and during other travel-related activities has had, and may continue to have, a material adverse effect on the public's perception of us, which has harmed, and may continue to harm, our reputation and business. We have incurred, and expect that we will continue to incur, COVID-19-related costs as we sanitize aircraft, implement additional hygiene-related protocols and take other actions to limit the threat of infection among our employees and passengers and combat negative customer perceptions of the health and safety of travel on our aircraft and at our terminals. Negative public perceptions could, in turn, result in adverse publicity for the Company, cause harm to the Company's brand and reduce travel demand on the Company's flights, or the flights of its codeshare partners or regional carriers.

Terrorist attacks, international hostilities or other security events, or the fear of terrorist attacks or hostilities, even if not made directly on the airline industry, could negatively affect the Company and the airline industry.

Terrorist attacks or international hostilities, even if not made on or targeted directly at the airline industry, or the fear of or the precautions taken in anticipation of such attacks (including elevated national threat warnings, travel restrictions, selective cancellation or redirection of flights and new security regulations) could materially and adversely affect the Company and the airline industry. Security events pose a significant risk to our passenger and cargo operations. These events could include acts of violence in public areas that we cannot control. The Company's financial resources may not be sufficient to absorb the adverse effects of any future terrorist attacks, international hostilities or other security events. Any such events could have a material adverse impact on the Company's financial condition, liquidity and operating results. In addition, due to threats against the aviation industry, the Company has incurred, and may continue to incur, significant expenditures to comply with security-related requirements to mitigate the threats and ensure the safety of our employees and customers. With the need to implement proper security measures, and the need to ensure the efficacy and efficiency of security inspection throughput to support the pace of our operations, it is unlikely that we will be able to capture all security-related costs through increased fares, which could adversely affect our operating results.

Increasing privacy and data security obligations or a significant data breach may adversely affect the Company's business.

In our regular business operations, we collect, process, store and transmit to commercial partners sensitive data, including personal information of our customers and employees such as payment processing information and information of our

48

business partners. The Company depends on the ability to use information we collect to provide our services and operate our business.

The Company must manage increasing legislative, regulatory and consumer focus on privacy issues and data security in a variety of jurisdictions across the globe. For example, the EU's General Data Protection Regulation imposes significant privacy and data security requirements, as well as potential for substantial penalties for non-compliance that have resulted in substantial adverse financial consequences to non-compliant companies. Also, some of the Company's commercial partners, such as credit card companies, have imposed data security standards that the Company must meet. These standards continue to evolve. The Company will continue its efforts to meet its privacy and data security obligations; however, it is possible that certain new obligations or customer expectations may be difficult to meet and could require changes in the Company's operating processes and increase the Company's costs.

Additionally, the Company must manage the increasing threat of continually evolving cybersecurity risks. Our network, systems and storage applications, and those systems and applications maintained by our third-party commercial partners (such as credit card companies and international airline partners), may be subject to attempts to gain unauthorized access, breach, malfeasance or other system disruptions, including those involving criminal hackers, denial of service attacks, hacktivists, state-sponsored actors, corporate espionage, employee malfeasance and human or technological error. In some cases, it is difficult to anticipate or to detect immediately such incidents and the damage caused thereby. In addition, as attacks by cybercriminals become more sophisticated, frequent and intense, the costs of proactive defense measures have increased and may continue to increase. In addition, several large organizations recently have been affected by "ransomware" attacks, and these highly publicized events may embolden individuals or groups to target our systems or the third party systems on which we rely. Furthermore, the Company's remote work arrangements make it more vulnerable to targeted activity from cybercriminals and significantly increase the risk of cyberattacks or other security breaches. While we continually work to safeguard our internal network, systems and applications, including through risk assessments, system monitoring, cybersecurity and data protection security policies, processes and technologies and employee awareness and training, and require third-party security standards, there is no assurance that such actions will be sufficient to prevent cyberattacks or data breaches.

Any such cyberattacks or data breaches could result in significant costs, including monetary damages, operational impacts, including service interruptions and delays, and reputational harm. Furthermore, the loss, disclosure, misappropriation of or access to sensitive Company information, customers', employees' or business partners' information or the Company's failure to meet its privacy obligations could result in legal claims or proceedings, penalties and remediation costs. A significant data breach or the Company's failure to meet its obligations may adversely affect the Company's operations, reputation, relationships with our business partners, business, operating results and financial condition.

Disruptions to our regional network and United Express flights provided by third-party regional carriers could adversely affect our business, operating results and financial condition.

The Company has contractual relationships with various regional carriers to provide regional aircraft service branded as United Express. These regional operations are an extension of the Company's mainline network and complement the Company's operations by carrying traffic that connects to mainline service and allows flights to smaller cities that cannot be provided economically with mainline aircraft. The Company's business and operations are dependent on its regional flight network, with regional capacity accounting for approximately 14.6% of the Company's total capacity for the year ended December 31, 2020.

Although the Company has agreements with its regional carriers that include contractually agreed performance metrics, each regional carrier is a separately certificated commercial air carrier, and the Company does not control the operations of these carriers. A number of factors may impact the Company's regional network, including weather-related effects, seasonality and any significant declines in demand for air travel services, including as a result of the on-going COVID-19 pandemic.

In addition, the decrease in qualified pilots driven by changes to federal regulations has adversely impacted and could continue to affect the Company's regional flying. For example, the FAA's expansion of minimum pilot qualification standards, including a requirement that a pilot have at least 1,500 total flight hours, as well as the FAA's revised pilot flight and duty time requirements under Part 117 of the Federal Aviation Regulations, have contributed to a smaller supply of pilots available to regional carriers. The decrease in qualified pilots resulting from the regulations as well as factors including a decreased student pilot population and a shrinking U.S. military from which to hire qualified pilots, could adversely impact the Company's operations and financial condition, and could also require the Company to reduce regional carrier flying.

If, as a result of the COVID-19 pandemic, the pilot shortage or another significant disruption to our regional network, one or more of the regional carriers with which the Company has relationships is unable to perform its obligations over an

49

extended period of time, there could be a material adverse effect on the Company's business, operating results and financial condition.

Our significant investments in other airlines, equipment manufacturers and other aviation industry participants, and the commercial relationships that we have with those entities, may not produce the returns or results we expect.

An important part of the Company's strategy to expand its global network has included making significant investments in other airlines, both domestically and in other parts of the world, as well as in other aviation industry participants, including producers of sustainable aviation fuel, manufacturers of electric and other new generation aircraft. The Company recently announced the formation of United Airlines Ventures ("UAV"), a corporate venture fund through which the Company intends to continue to invest in emerging companies that have the potential to influence the future of travel, concentrating on sustainability concepts that will complement United's goal of net zero emissions by 2050 as well as aerospace developments and innovative technologies. The Company has made investments in participants in various aspects of the aviation industry, including Archer Aviation Inc., Boom Technology Inc., Heart Aerospace, 1PointFive, Inc., Fulcrum BioEnergy, Inc., Journera, Inc. and Clear.

In addition to these investments, the Company has also invested in other airlines and expanded its commercial relationships with these carriers. For example, in January 2019, the Company completed the acquisition of a 49.9% interest in ManaAir LLC ("ManaAir"), which, as of immediately following the closing of that investment, owns 100% of the equity interests in ExpressJet Airlines, LLC ("ExpressJet"). The Company also has minority equity interests in CommutAir and Republic Airways Holdings Inc. See Note 9 to the financial statements included in Part II, Item 8 of the 2020 Form 10-K and Note 6 to the financial statements included in Part I, Item I of this report for additional information regarding the Company's investments in regional airlines. The Company also has significant investments in several Latin American airlines, including in Avianca Holdings, S.A. ("AVH") and BRW Aviation LLC ("BRW"), an affiliate of Synergy Aerospace Corporation and the majority shareholder of AVH, and in Azul Linhas Aéreas Brasileiras S.A. ("Azul"). In the future, the Company's regional and global business strategy could include entering into JBAs, commercial agreements and strategic alliances with other carriers, and possibly making loan transactions with, and non-controlling investments in, such carriers.

These transactions and relationships involve significant challenges and risks. Many of the companies in which the Company has invested are developing new and unproved technology. In addition, the Company faces competition in forming and maintaining relationships with other carriers, since there are a limited number of potential arrangements, and other airlines and industry participants are looking to enter into similar relationships. With regard to some of the airline investments, the Company is dependent on these other carriers for significant aspects of its network in the regions in which they operate. While the Company works closely with these carriers, each is a separately certificated commercial air carrier, and the Company does not have control over their operations, strategy, management or business methods. And not only are these airlines subject to a number of the same risks as the Company's business, which are described elsewhere in this Part II, Item 1A. Risk Factors, including the impact of the COVID-19 pandemic, competitive pressures on pricing, demand and capacity, changes in aircraft fuel pricing, and the impact of global and local political and economic conditions on operations and customer travel patterns, among others, they are also subject to their own distinct financial and operational risks.

As a result of these and other factors, the Company has not received, and may in the future not receive, satisfactory or expected returns on certain of its investments or repayment of invested or loaned funds. For example, we recorded a full credit loss allowance for the Company's $456 million term loan to BRW following BRW's default on such loan and the subsequent bankruptcy filing of BRW's subsidiary AVH, the parent of Aerovías del Continente Americano S.A. ("Avianca"), and the Company expects to pay $217 million to Kingsland Holdings Limited if, as expected, BRW defaults on the cooperation payment owed to Kingsland and guaranteed by the Company. In addition, the Company's $150 million senior secured convertible term loan to AVH, which was subsequently refinanced, or "rolled up", as a Tranche B loan in AVH's $2 billion debtor-in-possession financing, may not be repaid, and/or may be converted into new equity of AVH, if and when it emerges from bankruptcy. Finally, as the Company exercised its right to withdraw all aircraft from its capacity purchase agreement with ExpressJet, and, as of October 1, 2020 ExpressJet no longer provides regional capacity services to United, the Company's investment in ManaAir may not be recovered in full or at all. See Notes 8, 9, 11 and 13 to the financial statements included in Part II, Item 8 of the 2020 Form 10-K and Notes 6 and 7 to the financial statements included in Part I, Item I of this report for additional information regarding the Company's investments in AVH and Azul, its capacity purchase arrangements with ExpressJet and the Company's guarantee of the cooperation payment referenced above, respectively.

Further, the Company's investments, including its investments through UAV, may not generate the revenue or operational synergies the Company expects, and they may distract management focus from the Company's operations or other strategic options. The Company may also be subject to consequences from any illegal conduct of JBA partners, including for failure to comply with anti-corruption laws such as the U.S. Foreign Corrupt Practices Act. Furthermore, the Company's relationships with these entities may be subject to the laws and regulations of non-U.S. jurisdictions in which these entities are

50

located or conduct business. In addition, any political or regulatory change in these jurisdictions that negatively impacts or prohibits the Company's arrangements with these entities could have an adverse effect on the Company's operating results or financial condition. Finally, the Company's reliance on other carriers in the regions in which they operate may negatively impact the Company's regional and global operations and results if those carriers continue to be impacted by the COVID-19 pandemic and other general business risks discussed above or perform below the Company's expectations or needs and are not able to effectively mitigate these impacts or restore performance levels.

Any one or more of these events could have a material adverse effect on the Company's operating results or financial condition.

The airline industry may undergo further change with respect to alliances and JBAs or due to consolidations, any of which could have a material adverse effect on the Company.

The Company faces, and may continue to face, strong competition from other carriers due to the modification of alliances and formation of new JBAs. Carriers may improve their competitive positions through airline alliances, slot swaps and/or JBAs. Certain types of airline JBAs further competition by allowing multiple airlines to coordinate routes, pool revenues and costs, and enjoy other mutual benefits, achieving many of the benefits of consolidation. Open Skies agreements, including the longstanding agreements between the United States and each of the EU, Canada, Japan, Korea, New Zealand, Australia, Colombia and Panama, as well as the more recent agreements between the United States and each of Mexico and Brazil, may also give rise to better integration opportunities among international carriers. Movement of airlines between current global airline alliances could reduce joint network coverage for members of such alliances while also creating opportunities for JBAs and bilateral alliances that did not exist before such realignment. Further airline and airline alliance consolidations or reorganizations could occur in the future. The Company routinely engages in analyses and discussions regarding its own strategic position, including current and potential alliances, asset acquisitions and divestitures and may have future discussions with other airlines regarding strategic activities. If other airlines participate in such activities, those airlines may significantly improve their cost structures or revenue generation capabilities, thereby potentially making them stronger competitors of the Company and potentially impairing the Company's ability to realize expected benefits from its own strategic relationships.

Orders for new aircraft typically must be placed years in advance of scheduled deliveries, and changes in the Company's network strategy over time or other factors outside of the Company's control may make aircraft on order less economic for the Company, result in costs related to modification or termination of aircraft orders or cause the Company to enter into orders for new aircraft on less favorable terms, and any inability to accept or integrate new aircraft into the Company's fleet as planned could increase costs or affect the Company's flight schedules.

The Company's orders for new aircraft are typically made years in advance of actual delivery of such aircraft, and the financial commitment required for purchases of new aircraft is substantial. As of June 30, 2021, the Company had firm commitments to purchase 553 new aircraft from The Boeing Company ("Boeing") and Airbus S.A.S. ("Airbus"), as well as related agreements with engine manufacturers, maintenance providers and others. As of June 30, 2021, the Company's commitments relating to the acquisition of aircraft and related spare engines, aircraft improvements and other related obligations aggregated to a total of approximately $35.3 billion.

Subsequent to the Company placing an order for new aircraft, the Company's network strategy may change. As a result, the Company's preference for a particular aircraft that it has ordered, often years in advance, may be decreased or eliminated. If the Company were to modify or terminate any of its existing aircraft order commitments, it may be responsible for material liabilities to its counterparties arising from any such modification. In particular, during the second quarter of 2021, we announced the firm orders of 200 Boeing 737 MAX aircraft and 70 Airbus A321neo aircraft, which was the largest order in the Company's history, as part of the Company's "United Next" strategy. If future market conditions are not consistent with our expectations for increased customer demand, resulting in a modification or termination of these orders, we could incur significant contractual liabilities, and our financial condition could be adversely impacted.

Additionally, the Company may have a need for additional aircraft that are not available under its existing orders. In such cases, the Company may seek to acquire aircraft from other sources, such as through lease arrangements, which may result in higher costs or less favorable terms, or through the purchase or lease of used aircraft. The Company may not be able to acquire such aircraft when needed on favorable terms or at all. Furthermore, if, for any reason, the Company is unable to accept deliveries of new aircraft or integrate such new aircraft into its fleet as planned, the Company may face higher financing and operating costs than planned, or be required to seek extensions of the terms for certain leased aircraft or otherwise delay the exit of other aircraft from its fleet. Such unanticipated extensions or delays may require the Company to operate existing aircraft beyond the point at which it is economically optimal to retire them, resulting in increased maintenance costs, or reductions to the Company's schedule, thereby reducing revenues.

51

The imposition of new tariffs, or any increase in existing tariffs, on the importation of commercial aircraft that the Company orders may result in higher costs. For example, in October 2019, the United States imposed tariffs on certain imports from the EU, including a customs duty at an ad valorem rate of 10% on new commercial aircraft, which rate, in February 2020, was increased to 15%. These tariffs apply to certain new Airbus aircraft that we have on order. Additionally, in December 2020, the United States imposed tariffs on certain aircraft components from France and Germany. In June 2021, the United States and the EU reached an understanding in principle relating to commercial airlines to guide their cooperation with respect to their intent to suspend such tariffs for a period of five years. While the scope and rate of these tariffs are subject to change, if and to the extent these tariffs are imposed on us, they could increase the effective cost of, among other things, new Airbus aircraft and aircraft components.

A majority of the Company's aircraft and certain parts are sourced from single suppliers; therefore, the Company would be materially and adversely affected if it were unable to obtain timely deliveries, additional equipment or support from any of these suppliers.

The Company currently sources the majority of its aircraft and many related aircraft parts from Boeing. In addition, our aircraft suppliers are dependent on other suppliers for certain other aircraft parts. Therefore, if the Company is unable to acquire additional aircraft from Boeing, or if Boeing fails to make timely deliveries of aircraft (whether as a result of any failure or delay in obtaining regulatory approval or certification for new model aircraft, such as the 737 MAX 10 aircraft, which has not yet been certified, or manufacturing delays or otherwise) or to provide adequate support for its products, including with respect to the aircraft subject to firm orders under our "United Next" plan, the Company's operations could be materially and adversely affected. The Company is also dependent on a limited number of suppliers for aircraft engines and certain other aircraft parts and could, therefore, also be materially and adversely affected in the event of the unavailability of these engines and other parts.

Union disputes, employee strikes or slowdowns, and other labor-related disruptions could adversely affect the Company's operations and could result in increased costs that impair its financial performance.

United is a highly unionized company. As of June 30, 2021, the Company and its subsidiaries had approximately 84,400 employees, of whom approximately 85% were represented by various U.S. labor organizations. See Part I, Item 1. Business-Human Capital, of the 2020 Form 10-K for additional information on our represented employee groups and collective bargaining agreements.

There is a risk that unions or individual employees might pursue judicial or arbitral claims arising out of changes implemented as a result of the Company entering into collective bargaining agreements with its represented employee groups. There is also a possibility that employees or unions could engage in job actions such as slowdowns, work-to-rule campaigns, sick-outs or other actions designed to disrupt the Company's normal operations, in an attempt to pressure the Company in collective bargaining negotiations. Although the RLA makes such actions unlawful until the parties have been lawfully released to self-help, and the Company can seek injunctive relief against premature self-help, such actions can cause significant harm even if ultimately enjoined. Similarly, if the operations of our third-party regional carriers, ground handlers or other vendors are impacted by labor-related disruptions, our operations could be adversely affected. In addition, collective bargaining agreements with the Company's represented employee groups increase the Company's labor costs, which increase could be material.

Extended interruptions or disruptions in service at major airports where we operate could have a material adverse impact on our operations.

The airline industry is heavily dependent on business models that concentrate operations in major airports in the United States and throughout the world. An extended interruption or disruption at an airport where we have significant operations could have a material impact on our business, financial condition and results of operation.

We operate principally through our domestic hubs in Newark, Chicago O'Hare, Denver, Houston Bush, LAX, Guam, SFO and Washington Dulles. Substantially all of our flights either originate in or fly into one of these locations. A significant interruption or disruption in service at one of our hubs or other airports where we have a significant presence resulting from ATC delays, weather conditions, natural disasters, growth constraints, relations with third-party service providers, failure of computer systems, disruptions to government agencies or personnel (including as a result of government shutdowns), disruptions at airport facilities or other key facilities used by us to manage our operations, labor relations, power supplies, fuel supplies, terrorist activities, international hostilities or otherwise could result in the cancellation or delay of a significant portion of our flights and, as a result, could have a material impact on our business, operating results and financial condition. We have minimal control over the operation, quality or maintenance of these services or whether vendors will improve or continue to provide services that are essential to our business.

52

The Company's operating results fluctuate due to seasonality and other factors associated with the airline industry, many of which are beyond the Company's control.

Due to greater demand for air travel during the spring and summer months, revenues in the airline industry in the second and third quarters of the year are generally stronger than revenues in the first and fourth quarters of the year, which are periods of lower travel demand. The Company's operating results generally reflect this seasonality, but have also been impacted by numerous other factors that are not necessarily seasonal, including, among others, extreme or severe weather, outbreaks of disease or pandemics, ATC congestion, geological events, political instability, terrorism, natural disasters, changes in the competitive environment due to industry consolidation, tax obligations, general economic conditions and other factors. As a result, the Company's quarterly operating results are not necessarily indicative of operating results for an entire year and historical operating results in a quarterly or annual period are not necessarily indicative of future operating results.

The Company may never realize the full value of its intangible assets or its long-lived assets causing it to record impairments that may negatively affect its financial condition and operating results.

In accordance with applicable accounting standards, the Company is required to test its indefinite-lived intangible assets for impairment on an annual basis, or more frequently where there is an indication of impairment. In addition, the Company is required to test certain of its other assets for impairment where there is any indication that an asset may be impaired.

The Company may be required to recognize losses in the future due to, among other factors, extreme fuel price volatility, tight credit markets, government regulatory changes, decline in the fair values of certain tangible or intangible assets, such as aircraft, route authorities, airport slots and frequent flyer database, unfavorable trends in historical or forecasted results of operations and cash flows and an uncertain economic environment, as well as other uncertainties. For example, in 2021, the Company recorded $59 million of impairments primarily related to 64 Embraer EMB 145LR aircraft and related engines that United is retiring from its regional aircraft fleet, and in 2020, the Company recorded impairment charges of $130 million for its China routes, primarily as a result of the COVID-19 pandemic and the Company's subsequent suspension of flights to China, $38 million for its right-of-use asset associated with an embedded aircraft lease under a CPA, primarily as a result of reduced cash flows from the COVID-19 pandemic, and $94 million related to certain of the Company's fleet of Boeing 757 aircraft, and $56 million with respect to various cancelled facility, aircraft induction and information technology capital projects as a result of the COVID-19 pandemic's impact on our operations. In addition, in 2019, the Company recorded impairment charges of $90 million associated with its Hong Kong routes, resulting in the full impairment of these assets. The Company can provide no assurance that a material impairment loss of tangible or intangible assets will not occur in a future period. The value of the Company's aircraft could be impacted in future periods by changes in supply and demand for these aircraft. Such changes in supply and demand for certain aircraft types could result from the grounding of aircraft. An impairment loss could have a material adverse effect on the Company's financial condition and operating results.

Any damage to our reputation or brand image could adversely affect our business or financial results.

We operate in a public-facing industry and maintaining a good reputation is critical to our business. The Company's reputation or brand image could be adversely impacted by any failure to maintain satisfactory practices for all of our operations and activities, any failure to achieve and/or make progress toward our environmental and sustainability goals or our diversity, equity and inclusion goals, public pressure from investors or policy groups to change our policies, customer perceptions of our advertising campaigns, sponsorship arrangements or marketing programs, customer perceptions of our use of social media, or customer perceptions of statements made by us, our employees and executives, agents or other third parties. Damage to our reputation or brand image or loss of customer confidence in our services could adversely affect our business and financial results, as well as require additional resources to rebuild our reputation.

The Company's ability to use its net operating loss carryforwards and certain other tax attributes to offset future taxable income for U.S. federal income tax purposes may be significantly limited due to various circumstances, including certain possible future transactions involving the sale or issuance of UAL common stock, or if taxable income does not reach sufficient levels.

As of December 31, 2020, UAL reported consolidated U.S. federal net operating loss ("NOL") carryforwards of approximately $11.0 billion.

The Company's ability to use its NOL carryforwards and certain other tax attributes will depend on the amount of taxable income it generates in future periods. As a result, certain of the Company's NOL carryforwards and other tax attributes may expire before it can generate sufficient taxable income to use them in full.

53

In addition, the Company's ability to use its NOL carryforwards and certain other tax attributes to offset future taxable income may be limited if it experiences an "ownership change" as defined in Section 382 of the Internal Revenue Code of 1986, as amended ("Section 382"). An ownership change generally occurs if certain stockholders increase their aggregate percentage ownership of a corporation's stock by more than 50 percentage points over their lowest percentage ownership at any time during the testing period, which is generally the three-year period preceding any potential ownership change.

In general, a corporation that experiences an ownership change will be subject to an annual limitation on its pre-ownership change NOLs and certain other tax attribute carryforwards equal to the value of the corporation's stock immediately before the ownership change, multiplied by the applicable long-term, tax-exempt rate posted by the IRS. Any unused annual limitation may, subject to certain limits, be carried over to later years, and the limitation may, under certain circumstances, be increased by built-in gains in the assets held by such corporation at the time of the ownership change. This limitation could cause the Company's U.S. federal income taxes to be greater, or to be paid earlier, than they otherwise would be, and could cause a portion of the Company's NOLs and certain other tax attributes to expire unused. Similar rules and limitations may apply for state income tax purposes.

For purposes of determining whether there has been an "ownership change," the change in ownership as a result of purchases by "5-percent shareholders" will be aggregated with certain changes in ownership that occurred over the three-year period ending on the date of such purchases. Potential future transactions involving the sale or issuance of UAL common stock may increase the possibility that the Company will experience a future ownership change under Section 382. Such transactions may include the exercise of warrants issued in connection with the CARES Act programs, the issuance of UAL common stock upon the conversion of any convertible debt that UAL may issue in the future, the repurchase of any debt with UAL common stock, any issuance of UAL common stock for cash, and the acquisition or disposition of any stock by a stockholder owning 5% or more of the outstanding shares of UAL common stock, or a combination of the foregoing. If we were to experience an "ownership change," it is possible that the Company's NOLs and certain other tax attribute carryforwards could expire before we would be able to use them to offset future income tax obligations.

On December 4, 2020, the board of directors of the Company adopted a tax benefits preservation plan (the "Plan") in order to preserve the Company's ability to use its NOLs and certain other tax attributes to reduce potential future income tax obligations. At the Company's annual meeting of stockholders held on May 26, 2021, the Company's stockholders approved the Plan. The Plan is designed to reduce the likelihood that the Company experiences an "ownership change" by deterring certain acquisitions of Company securities. There is no assurance, however, that the deterrent mechanism in the Plan will be effective, and such acquisitions may still occur. In addition, the Plan may adversely affect the marketability of UAL common stock by discouraging existing or potential investors from acquiring UAL common stock or additional shares of UAL common stock because any non-exempt third party that acquires 4.9% or more of the then-outstanding shares of UAL common stock would suffer substantial dilution of its ownership interest in the Company.

Risks Relating to Legal and Regulatory Compliance

The airline industry is subject to extensive government regulation, which imposes significant costs and may adversely impact our business, operating results and financial condition.

Airlines are subject to extensive regulatory and legal oversight. Compliance with U.S. and international regulations imposes significant costs and may have adverse effects on the Company. Laws, regulations, taxes and airport rates and charges, both domestically and internationally, have been proposed from time to time that could significantly increase the cost of airline operations or reduce airline revenue. The airline industry is heavily taxed, and additional taxation could negatively impact our business.

United provides air transportation under certificates of public convenience and necessity issued by the DOT. If the DOT altered, amended, modified, suspended or revoked these certificates, it could have a material adverse effect on the Company's business. The DOT also regulates consumer protection and, through its investigations or rulemaking authority (including, for example, any rulemakings or initiatives in response to the Executive Order on Promoting Competition in the American Economy issued by the President on July 9, 2021), could impose restrictions that materially impact the Company's business. The FAA regulates the safety of United's operations. United operates pursuant to an air carrier operating certificate issued by the FAA. The FAA's regulations include stringent pilot flight and duty time requirements under Part 117 of the Federal Aviation Regulations, as well as minimum qualifications for air carrier first officers. From time to time, the FAA also issues orders, airworthiness directives and other regulations relating to the maintenance and operation of aircraft that require material expenditures or operational restrictions by the Company. These FAA orders and directives have resulted in the temporary grounding of an entire aircraft type if the FAA identifies design, manufacturing, maintenance or other issues requiring immediate corrective action (including the FAA Emergency Airworthiness Directive grounding our Boeing 777 Pratt & Whitney powered aircraft). These FAA directives or requirements could have a material adverse effect on the Company.

54

In 2018, the U.S. Congress approved a five-year reauthorization for the FAA, which encompasses significant aviation tax and policy-related issues. The law includes a range of policy changes related to airline customer service and aviation safety. Implementation of some items continues into the Biden Administration and, depending on how they are implemented, could impact our operations and costs. U.S. Congressional action in response to the COVID-19 pandemic has provided funding for U.S. airlines, in both grants and loans. The U.S. Congress has imposed limited conditions on airlines accepting funding, including workforce retention and minimum service requirements. With the change in control of the U.S. Congress, under the Biden Administration, any future funding or other pandemic relief could include additional requirements that could impact our operations and costs. Additionally, the U.S. Congress may consider legislation related to environmental issues or increases to the U.S. federal corporate income tax rate, as outlined in the Biden Administration's tax plan or otherwise, which could impact the Company and the airline industry.

The Company's operations may also be adversely impacted due to the existing antiquated ATC system utilized by the U.S. government and regulated by the FAA. During peak travel periods in certain markets, the current ATC system's inability to handle demand has led to short-term capacity constraints imposed by government agencies and resulted in delays and disruptions of air traffic. In addition, the current system will not be able to effectively handle projected future air traffic growth. The outdated technologies also cause the ATC to be less resilient in the event of a failure, causing flight cancellations and delays. Imposition of these ATC constraints on a long-term basis may have a material adverse effect on the Company's operations. Failure to update the ATC system in a timely manner and the substantial funding requirements of a modernized ATC system that may be imposed on air carriers may have an adverse impact on the Company's financial condition or operating results.

Access to landing and take-off rights, or "slots," at several major U.S. airports and many foreign airports served by the Company are, or recently have been, subject to government regulation. Certain of the Company's major hubs are among the most congested airports in the United States and have been or could be the subject of regulatory action that might limit the number of flights and/or increase costs of operations at certain times or throughout the day. The DOT (including FAA) may limit the Company's airport access by limiting the number of departure and arrival slots at high density traffic airports, which could affect the Company's ownership and transfer rights, and local airport authorities may have the ability to control access to certain facilities or the cost of access to their facilities, which could have an adverse effect on the Company's business. The DOT historically has taken actions with respect to airlines' slot holdings that airlines have challenged; if the DOT were to take actions that adversely affect the Company's slot holdings, the Company could incur substantial costs to preserve its slots or may lose slots. If slots are eliminated at an airport, or if the number of hours of operation governed by slots is reduced at an airport, the lack of controls on take-offs and landings could result in greater congestion both at the affected airport or in the regional airspace (e.g., the New York City metropolitan region airspace) and could significantly impact the Company's operations. In addition, as airports around the world become more congested, space, facility, and infrastructure constraints may prevent the Company from maintaining existing service and/or implementing new service in a commercially viable manner. Further, the Company's operating costs at airports, including the Company's major hubs, may increase significantly because of capital improvements at such airports that the Company may be required to fund, directly or indirectly. Such costs could be imposed by the relevant airport authority without the Company's approval and may have a material adverse effect on the Company's financial condition. Because of airport infrastructure updates and other factors, the Company has experienced increased space rental rates at various airports in its network. Further, the Company cannot control decisions by other airlines to reduce their capacity. When this occurs, certain fixed airport costs are allocated among fewer total flights, which can result in increased landing fees and other costs for the Company. In light of constraints on existing facilities, there is presently a significant amount of capital spending underway at major airports in the United States, including large projects underway at a number of airports where we have significant operations, such as Chicago O'Hare International Airport (ORD), Los Angeles International Airport (LAX), LaGuardia Airport (LGA) and Ronald Reagan Washington National Airport (DCA). This spending is expected to result in increased costs to airlines and the traveling public that use those facilities as the airports seek to recover their investments through increased rental, landing and other facility costs. In some circumstances, such costs could be imposed by the relevant airport authority without our approval. Accordingly, our operating costs are expected to increase significantly at many airports at which we operate, including a number of our hubs and gateways, as a result of capital spending projects currently underway and additional projects that we expect to commence over the next several years.

The ability of carriers to operate flights on international routes between the United States and other countries is highly regulated. Applicable arrangements between the United States and foreign governments may be amended from time to time, government policies with respect to airport operations may be revised, and the availability of appropriate slots or facilities may change. The Company currently operates a number of flights on international routes under government arrangements, regulations or policies that designate the number of carriers permitted to operate on such routes, the capacity of the carriers providing services on such routes, the airports at which carriers may operate international flights, or the number of carriers allowed access to particular airports. In addition, the pandemic has resulted in, and created the potential for, increased regulatory burdens in the U.S. and around the globe. These include but are not limited to closure of international borders to

55

flights and/or passengers from specific countries, passenger and crew quarantine requirements, and other regulations promulgated to protect public health but that have a negative impact on travel and airline operations. Any limitations, additions or modifications to such arrangements, regulations or policies could have a material adverse effect on the Company's financial condition and operating results. Additionally, a change in law, regulation or policy for any of the Company's international routes, such as Open Skies, could have a material adverse impact on the Company's financial condition and operating results and could result in the impairment of material amounts of related tangible and intangible assets. In addition, competition from revenue-sharing JBAs and other alliance arrangements by and among other airlines could impair the value of the Company's business and assets on the Open Skies routes. The Company's plans to enter into or expand U.S. antitrust immunized alliances and JBAs on various international routes are subject to receipt of approvals from applicable U.S. federal authorities and obtaining other applicable foreign government clearances or satisfying the necessary applicable regulatory requirements. There can be no assurance that such approvals and clearances will be granted or will continue in effect upon further regulatory review or that changes in regulatory requirements or standards can be satisfied.

See Part I, Item 1. Business-Industry Regulation, of the 2020 Form 10-K for additional information on government regulation impacting the Company.

We are subject to many forms of environmental regulation and liability and risks associated with climate change, and may incur substantial costs as a result.

Many aspects of the Company's operations are subject to increasingly stringent federal, state, local and international laws protecting the environment, including those relating to emissions to the air, water discharges, safe drinking water, the use and management of hazardous materials and wastes, and noise emissions. Compliance with existing and future environmental laws and regulations can require significant expenditures and violations can lead to significant fines and penalties. In addition, from time to time we are identified as a responsible party for environmental investigation and remediation costs under applicable environmental laws due to the disposal of hazardous substances generated by our operations. We could also be subject to environmental liability claims from various parties, including airport authorities, related to our operations at our owned or leased premises or the off-site disposal of waste generated at our facilities.

We may incur substantial costs as a result of changes in weather patterns due to climate change. Increases in the frequency, severity or duration of severe weather events such as thunderstorms, hurricanes, flooding, typhoons, tornados and other severe weather events could result in increases in delays and cancellations, turbulence-related injuries and fuel consumption to avoid such weather, any of which could result in significant loss of revenue and higher costs. In addition, we could incur significant costs to improve the climate resiliency of our infrastructure and supply chain and otherwise prepare for, respond to, and mitigate the effects of climate change. We are not able to predict accurately the materiality of any potential losses or costs associated with the effects of climate change.

To mitigate climate change risks, CORSIA has been developed by ICAO, a UN specialized agency. CORSIA is intended to create a single global market-based measure to achieve carbon-neutral growth for international aviation after 2020 through airline purchases of carbon offset credits. The voluntary pilot and first phases of the program are expected to run from 2021 through 2023, and 2024 through 2026, respectively, with airlines having until January 2025 to cancel eligible emissions units to comply with their total offsetting requirements for the pilot phase. Certain CORSIA program aspects could potentially be affected by the results of the pilot phase of the program, and thus the impact of CORSIA cannot be fully predicted. However, CORSIA is expected to result in increased operating costs for airlines that operate internationally, including the Company.

In addition to CORSIA, in December 2020 the EPA adopted its own aircraft and aircraft engine GHG emissions standards, which are aligned with the 2017 ICAO airplane carbon dioxide emission standards. Other jurisdictions in which United operates have adopted or are considering GHG emissions reduction initiatives, which could impact various aspects of the Company's business. The final standards have been challenged by several states and environmental groups, and the Biden Administration has issued an executive order requiring a review of these final standards along with others issued by the prior presidential administration. On February 17, 2021, the United States Court of Appeals for the District of Columbia Circuit ordered to hold the challenge by the states and environmental groups in abeyance pending the EPA's review. The outcome of the legal challenge and administrative review cannot be predicted at this time. Furthermore, while the Company has voluntarily pledged to reduce 100% of our GHG emissions by 2050, the precise nature of future requirements and their applicability to the Company are difficult to predict, and the financial impact to the Company and the aviation industry would likely be adverse and could be significant if they vary significantly from the Company's own plans and strategy with respect to reducing GHG emissions.

See Part I, Item 1. Business-Industry Regulation-Environmental Regulation, of the 2020 Form 10-K for additional information on environmental regulation impacting the Company.

Risks Relating to Our Indebtedness

56

The Company has a significant amount of financial leverage from fixed obligations and may seek material amounts of additional financial liquidity in the short-term, and insufficient liquidity may have a material adverse effect on the Company's financial condition and business.

The Company has a significant amount of financial leverage from fixed obligations, including aircraft lease and debt financings, leases of airport property, secured loan facilities and other facilities, and other material cash obligations. In addition, the Company has substantial noncancelable commitments for capital expenditures, including for the acquisition of new and used aircraft and related spare engines.

As of June 30, 2021, we had total long-term debt of $34.2 billion and $1.75 billion available for borrowing under our revolving credit facility.

The Company's substantial level of indebtedness, the Company's non-investment grade credit ratings and the availability of Company assets as collateral for loans or other indebtedness, which available collateral has been reduced as a result of the financings in April 2021 secured by liens on certain international route authorities and related airport take-off and landing slots and gate leaseholds, may make it difficult for the Company to raise additional capital if needed to meet its liquidity needs on acceptable terms, or at all.

Although the Company's cash flows from operations and its available capital, including the proceeds from financing transactions, have been sufficient to meet its obligations and commitments to date, the Company's liquidity has been, and may in the future be, negatively affected by the risk factors discussed elsewhere in this Part II, Item 1A. Risk Factors, including risks related to future results arising from the COVID-19 pandemic. If the Company's liquidity is materially diminished, the Company's cash flow available for general corporate purposes may be materially and adversely affected. In particular, with respect to the $6.8 billion of senior secured notes and a secured term loan facility (the "MileagePlus Financing") secured by substantially all of the assets of Mileage Plus Holdings, LLC, a direct wholly-owned subsidiary of United ("MPH"), and Mileage Plus Intellectual Property Assets, Ltd., an indirect wholly-owned subsidiary of MPH ("MIPA"), the cash flows generated by the MileagePlus business are required to first satisfy interest and principal due thereunder. Therefore, the cash generated by the MileagePlus program is not fully available for our operations or to satisfy our other indebtedness obligations for the seven-year term of the MileagePlus Financing debt. This limitation on our cash flows could have a material adverse effect on our operations and flexibility.

A material reduction in the Company's liquidity could also result in the Company not being able to timely pay its leases and debts or comply with material provisions of its contractual obligations, including covenants under its financing and credit card processing agreements. Moreover, as a result of the Company's financing activities in response to the COVID-19 pandemic, the number of financings with respect to which such covenants and provisions apply has increased, thereby subjecting the Company to more substantial risk of default, cross-default and cross-acceleration in the event of breach, and additional covenants and provisions could become binding on the Company in the event it continues to seek additional liquidity. In addition, several of the Company's debt agreements contain covenants that, among other things, restrict the ability of the Company and its subsidiaries to incur additional indebtedness. The Company has agreements with financial institutions that process customer credit card transactions for the sale of air travel and other services. Under certain of the Company's credit card processing agreements, the financial institutions in certain circumstances have the right to require that the Company maintain a reserve equal to a portion (or potentially all) of advance ticket sales that have been processed by that financial institution, but for which the Company has not yet provided the air transportation. Such financial institutions may require cash or other collateral reserves to be established or withholding of payments related to receivables to be collected, including if the Company does not maintain certain minimum levels of unrestricted cash, cash equivalents and short-term investments. In light of the effect COVID-19 is having on demand and, in turn, capacity, the Company has seen an increase in demand from consumers for refunds on their tickets, and we anticipate some level of increased demand for refunds on tickets will continue to be the case for the near future. Refunds lower our liquidity and put us at risk of triggering liquidity covenants in these processing agreements and, in doing so, could force us to post cash collateral with the credit card companies for advance ticket sales. The Company also maintains certain insurance- and surety-related agreements under which counterparties have required, and may require, additional collateral.

In addition to the foregoing, the degree to which we are leveraged could have important consequences to holders of our securities, including the following:

•we must dedicate a substantial portion of cash flow from operations to the payment of principal and interest on applicable indebtedness, which, in turn, reduces funds available for operations and capital expenditures;

•our flexibility in planning for, or reacting to, changes in the markets in which we compete may be limited;

•we may be at a competitive disadvantage relative to our competitors with less indebtedness;

57

•we are rendered more vulnerable to general adverse economic and industry conditions;

•we are exposed to increased interest rate risk given that a portion of our indebtedness obligations are at variable interest rates; and

•our credit ratings may be reduced and our debt and equity securities may significantly decrease in value.

Finally, as of June 30, 2021, the Company had $13.2 billion in variable rate indebtedness, all or a portion of which uses London interbank offered rates ("LIBOR") as a benchmark for establishing applicable rates. As most recently announced in November 30, 2020, LIBOR is expected to be phased out starting on January 1, 2022 for the one-week and two-month USD LIBOR settings and starting on July 1, 2023 for the remaining USD LIBOR settings. Although many of our LIBOR-based obligations provide for alternative methods of calculating the interest rate payable if LIBOR is not reported, the extent and manner of any future changes with respect to methods of calculating LIBOR or replacing LIBOR with another benchmark are unknown and impossible to predict at this time and, as such, may result in interest rates that are materially higher than current interest rates. If interest rates applicable to the Company's variable interest indebtedness increase, the Company's interest expense will also increase, which could make it difficult for the Company to make interest payments and fund other fixed costs and, in turn, adversely impact our cash flow available for general corporate purposes.

See Part I, Item 2., Management's Discussion and Analysis of Financial Condition and Results of Operations, of this report for additional information regarding the Company's liquidity as of June 30, 2021.

If we are not able to comply with the covenants in the MileagePlus Financing agreements, our lenders could accelerate the MileagePlus indebtedness, foreclose upon the collateral securing the MileagePlus indebtedness or exercise other remedies, which would have a material adverse effect on our business, results of operations and financial condition.

The covenants in the agreements governing the MileagePlus Financing contain a number of provisions that limit our ability to modify aspects of the MileagePlus program if such modifications would be reasonably expected to have a material adverse effect on the MileagePlus program or on our ability to pay the obligations under the MileagePlus Financing agreements. Moreover, the terms of such agreements also place certain restrictions on our establishing or owning another mileage or loyalty program and our ability to make material modifications to our agreements with certain MileagePlus partners. Furthermore, the MileagePlus Financing may also negatively affect certain material business relationships, and if any such relationship were to be materially impaired and/or terminated, we could experience a material adverse effect on our business, results of operations and financial condition.

The agreements governing the MileagePlus Financing restrict our ability to terminate or modify the intercompany agreements governing the relationship between United and the MileagePlus program, including the agreement governing the rate that United must pay MPH for the purchase of miles and United's obligation to make certain seat inventory available to MPH for redemption. Such restrictions are in addition to restrictions on the ability of the obligors under the MileagePlus indebtedness to make restricted payments, incur additional indebtedness, dispose of, create or incur certain liens on, or transfer or convey, the collateral securing the MileagePlus indebtedness, enter into certain transactions with affiliates, merge, consolidate, or sell assets, or designate certain subsidiaries as unrestricted. Complying with these covenants may restrict our ability to make material changes to the operation of the MPH business and may limit our ability to take advantage of business opportunities that may be in our long-term interest. We may also take actions, or omit to take actions, to comply with such covenants that could have a material adverse effect on our business and operations.

Our failure to comply with any of these covenants or restrictions could result in a default under the agreements governing the MileagePlus Financing, 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 us. In the case of an event of default under the agreements governing the MileagePlus Financing agreements, or a cross-default or cross-acceleration under our other indebtedness, we may not have sufficient funds available to make the required payments. If we are unable to repay amounts owed under the agreements governing the MileagePlus Financing, the lenders or noteholders thereunder may choose to exercise their remedies in respect of the collateral securing such indebtedness, including foreclosing upon the MileagePlus collateral, in which case we would lose the right to operate the MileagePlus program thereafter. The exercise of such remedies, especially the loss of the MileagePlus program, would have a material adverse effect on our business, results of operations and financial condition.

In connection with the MileagePlus Financing, we were required to contribute certain assets, including certain MileagePlus intellectual property, including brands and member data, to Mileage Plus Intellectual Property Assets, Ltd., an indirect wholly-owned subsidiary of MPH structured to be bankruptcy remote that serves as a co-issuer of the MileagePlus Financing indebtedness, the assets of which subsidiary are collateral for such indebtedness. United and MPH will have the right to use the contributed intellectual property pursuant to a license agreement with MIPA. Such license agreement will be

58

terminated, and our right to use such intellectual property will cease, upon specified termination events, including, but not limited to, our failure to assume the license agreement and various related intercompany agreements in a restructuring process. The termination of the license agreement would be an event of default under the agreements governing the MileagePlus Financing and in certain circumstances would trigger a liquidated damages payment in an amount that is several multiples of the principal amount of the MileagePlus Financing debt. Thus, the terms of the MileagePlus Financing limit our flexibility to manage our capital structure going forward, and as a result, in the future we may take actions to ensure that the MileagePlus Financing debt is satisfied or that the lenders' remedies under such debt are not exercised, potentially to the detriment of our other creditors.

Agreements governing our other debt include financial and other covenants. Failure to comply with these covenants could result in events of default.

In addition to the covenants in the MileagePlus Financing agreements discussed above, our other financing agreements include various financial and other covenants. Certain of these covenants require UAL or United, as applicable, to maintain minimum liquidity and/or minimum collateral coverage ratios. UAL's or United's ability to comply with these covenants may be affected by events beyond its control, including the overall industry revenue environment, the level of fuel costs and the appraised value of the collateral. In addition, our financing agreements contain other negative covenants customary for such financings. These covenants are subject to important exceptions and qualifications. If we fail to comply with these covenants and are unable to remedy or obtain a waiver or amendment, an event of default would result.

If an event of default were to occur, the lenders could, among other things, declare outstanding amounts immediately due and payable. In addition, an event of default or declaration of acceleration under one financing agreement could also result in an event of default under other of our financing agreements due to cross-default and cross-acceleration provisions. The acceleration of significant amounts of debt could require us to renegotiate, repay or refinance the obligations under our financing arrangements.

General Risk Factors

If we experience changes in, or are unable to retain, our senior management team or other key employees, our operating results could be adversely affected.

Much of our future success depends on the continued availability of skilled personnel with industry experience and knowledge, including our senior management team and other key employees. If we are unable to attract and retain talented, highly qualified senior management and other key employees, or if we are unable to effectively provide for the succession of senior management, our business may be adversely affected.

Current or future litigation and regulatory actions, or failure to comply with the terms of any settlement, order or arrangement relating to these actions, could have a material adverse impact on the Company.

From time to time, we are subject to litigation and other legal and regulatory proceedings relating to our business or investigations or other actions by governmental agencies, including as described in Part I, Item 3, Legal Proceedings, of the 2020 Form 10-K. No assurances can be given that the results of these or new matters will be favorable to us. An adverse resolution of lawsuits, arbitrations, investigations or other proceedings or actions could have a material adverse effect on our financial condition and operating results, including as a result of non-monetary remedies, and could also result in adverse publicity. Defending ourselves in these matters may be time-consuming, expensive and disruptive to normal business operations and may result in significant expense and a diversion of management's time and attention from the operation of our business, which could impede our ability to achieve our business objectives. Additionally, any amount that we may be required to pay to satisfy a judgment, settlement, fine or penalty may not be covered by insurance. If we fail to comply with the terms contained in any settlement, order or agreement with a governmental authority relating to these matters, we could be subject to criminal or civil penalties, which could have a material adverse impact on the Company. Under our charter and certain indemnification agreements that we have entered into (and may in the future enter into) with our officers, directors and certain third parties, we could be required to indemnify and advance expenses to them in connection with their involvement in certain actions, suits, investigations and other proceedings. There can be no assurance that any of these payments will not be material.

Increases in insurance costs or inadequate insurance coverage may materially and adversely impact our business, operating results and financial condition.

The Company could be exposed to significant liability or loss if its property and/or operations were to be affected by a natural catastrophe, aircraft accident or other event. The Company maintains insurance policies, including, but not limited to, terrorism, aviation hull and liability, workers' compensation and property and business interruption insurance, but we are not fully insured against all potential hazards and risks incident to our business. If the Company is unable to obtain sufficient

59

insurance with acceptable terms, the costs of such insurance increase materially, or if the coverage obtained is unable to pay or is insufficient relative to actual liability or losses that the Company experiences, whether due to insurance market conditions, policy limitations and exclusions or otherwise, our operations, operating results and financial condition could be materially and adversely affected.
