Revenue Environment and Outlook

“We generated record September quarter revenue, with total revenues 13 percent higher than the September quarter of 2022. With this performance, we expect to deliver a record September quarter unit revenue premium to the industry, reflecting the strength of Delta’s diverse revenue streams and continued brand momentum,” said Glen Hauenstein, Delta’s president.

“Robust demand for travel on Delta is continuing into the December quarter where we expect total revenue growth of 9 percent to 12 percent compared to the December quarter 2022 with total unit revenue (TRASM) expected to decline 2.5 percent to 4.5 percent. Within this outlook, Domestic and Transatlantic trends are consistent with the September quarter on a year-over-year basis, while unit revenue trends in the Pacific and Latin America are expected to modestly decelerate given capacity growth related to China re-opening and investment in our LATAM JV.”

· Demand for travel on Delta remains strong: Unit revenues in the September quarter were at the high-end of guidance, with adjusted total unit revenue (TRASM) down 2.5 percent year-over-year, including approximately one point of pressure from Cargo and MRO. Passenger unit revenue (PRASM) was down 1.5 percent year-over-year.

· Domestic demand environment steady: Domestic passenger revenue increased 6 percent versus 2022 on 11 percent more capacity, with domestic unit revenue down 4 percent year-over-year. Coastal hub load factors expanded year-over-year, driven by growing demand in Boston and New York. Business travel continues to improve as corporates announce return to office initiatives. Our recent corporate survey indicates that a significant majority of companies are expecting their travel volumes to increase or stay the same in the December quarter and into 2024.

· International strength extending through fall: International passenger revenue was 35 percent higher versus 2022 in the September quarter with record margins across all regions. Transatlantic revenue grew 34 percent with record PRASM on its largest schedule in Delta's history. Latin America revenue grew 20 percent versus 2022 driven by strength in South America as the LATAM JV delivers increased connectivity and synergies. For the year, we remain confident in finishing strong with record profitability across all three international entities.

· Growth in diversified revenue streams continues: Premium and other diversified revenue streams, including Loyalty, Cargo and MRO comprised 55 percent of total revenues year-to-date. Premium revenue growth of 17 percent year-over-year outpaced main cabin by 5 points, with total Loyalty revenue up 17 percent on strong co-brand acquisitions and spend growth. American Express remuneration for the September quarter was $1.7 billion, approximately 20 percent higher than September quarter 2022.

Cost Performance and Outlook

“For the December quarter, we expect non-fuel unit costs to be flat to 2% higher year-over-year as we realize the benefits of scale and efficiency while making investments in our people and operational reliability,” said Dan Janki, Delta’s chief financial officer. “Delivering operational excellence while driving efficiency remains a top priority.”

Note A: The following tables show reconciliations of non-GAAP financial measures. The reasons Delta uses these measures are described below. Reconciliations may not calculate due to rounding.

Delta sometimes uses information (“non-GAAP financial measures”) that is derived from the Consolidated Financial Statements, but that is not presented in accordance with accounting principles generally accepted in the U.S. (“GAAP”). Under the Securities and Exchange Commission rules, non-GAAP financial measures may be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for or superior to GAAP results. The tables below show reconciliations of non-GAAP financial measures used in this release to the most directly comparable GAAP financial measures.

Forward Looking Projections. Delta is not able to reconcile forward looking non-GAAP financial measures without unreasonable effort because the adjusting items such as those used in the reconciliations below will not be known until the end of the period and could be significant.

Adjustments. These reconciliations include certain adjustments to GAAP measures that are made to provide comparability between the reported periods, if applicable, and for the reasons indicated below:

Third-party refinery sales. Refinery sales to third parties, and related expenses, are not related to our airline segment. Excluding these sales therefore provides a more meaningful comparison of our airline operations to the rest of the airline industry.

MTM adjustments and settlements on hedges. Mark-to-market (“MTM”) adjustments are defined as fair value changes recorded in periods other than the settlement period. Such fair value changes are not necessarily indicative of the actual settlement value of the underlying hedge in the contract settlement period, and therefore we remove this impact to allow investors to better understand and analyze our core performance. Settlements represent cash received or paid on hedge contracts settled during the applicable period.

Loss on extinguishment of debt. This adjustment relates to early termination of a portion of our debt. Adjusting for these losses allows investors to better understand and analyze our core operational performance in the periods shown.

MTM adjustments on investments. Unrealized gains/losses result from our equity investments that are accounted for at fair value in non-operating expense. The gains/losses are driven by changes in stock prices, foreign currency fluctuations and other valuation techniques for investments in certain companies, particularly those without publicly-traded shares. Adjusting for these gains/losses allows investors to better understand and analyze our core operational performance in the periods shown.

Restructuring charges. During 2020, we recorded restructuring charges for items such as fleet impairments and voluntary early retirement and separation programs following strategic business decisions in response to the COVID-19 pandemic. During 2022, we recognized adjustments to certain of those restructuring charges, representing changes in our estimates.

Operating Cash Flow, adjusted. We present operating cash flow, adjusted because management believes adjusting for the following items provides a more meaningful measure for investors:

Net cash flows related to certain airport construction projects and other. Cash flows related to certain airport construction projects are included in our GAAP operating activities. We have adjusted for these items, which were primarily funded by cash restricted for airport construction, to provide investors a better understanding of the company's operating cash flow that is core to our operations in the periods shown.

Adjusted Net Debt. Delta uses adjusted total debt, including aircraft rent, in addition to adjusted debt and finance leases, to present estimated financial obligations. Delta reduces adjusted total debt by cash, cash equivalents, short-term investments and LGA restricted cash, resulting in adjusted net debt, to present the amount of assets needed to satisfy the debt. Management believes this metric is helpful to investors in assessing the company's overall debt profile.

Adjusted Non-Fuel Cost and Non-Fuel Unit Cost or Cost per Available Seat Mile, ("CASM-Ex")

We adjust operating expense and CASM for certain items described above, as well as the following items and reasons described below:

Aircraft fuel and related taxes. The volatility in fuel prices impacts the comparability of year-over-year financial performance. The adjustment for aircraft fuel and related taxes allows investors to better understand and analyze our non-fuel costs and year-over-year financial performance.

Profit sharing. We adjust for profit sharing because this adjustment allows investors to better understand and analyze our recurring cost performance and provides a more meaningful comparison of our core operating costs to the airline industry.

One-time pilot agreement expenses. In the March 2023 quarter, Delta pilots ratified a new four-year Pilot Working Agreement effective January 1, 2023. The agreement includes numerous work rule changes and pay rate increases during the four-year term, including an initial pay rate increase of 18%. The agreement also includes a provision for a one-time payment made upon ratification in the March 2023 quarter of $735 million. Additionally, we recorded adjustments to other benefit-related items of approximately $130 million. Adjusting for these expenses allows investors to better understand and analyze our core cost performance.

Adjusted Debt to Earnings Before Interest, Taxes, Depreciation, Amortization and Rent ("EBITDAR"). We present adjusted debt to EBITDAR because management believes this metric is helpful to investors in assessing the company's overall debt profile. Adjusted debt includes LGA bonds and operating lease liabilities. We calculate EBITDAR by adding depreciation and amortization to GAAP operating income and adjusting for the fixed portion of operating lease expense.

Gross Capital Expenditures. We adjust capital expenditures for the following items to determine gross capital expenditures for the reasons described below:

Financed aircraft acquisitions. This adjusts capital expenditures to reflect aircraft deliveries that are leased as capital expenditures. The adjustment is based on their original contractual purchase price or an estimate of the aircraft's fair value and provides a more meaningful view of our investing activities.

Net cash flows related to certain airport construction projects. Cash flows related to certain airport construction projects are included in capital expenditures. We have adjusted for these items because management believes investors should be informed that a portion of these capital expenditures from airport construction projects are either funded with restricted cash specific to these projects or reimbursed by a third party.

Free Cash Flow. We present free cash flow because management believes this metric is helpful to investors to evaluate the company's ability to generate cash that is available for use for debt service or general corporate initiatives. Free cash flow is also used internally as a component of our 2023 incentive compensation program. Free cash flow is defined as net cash from operating activities and net cash from investing activities, adjusted for (i) net redemptions of short-term investments, (ii) strategic investments and related, (iii) net cash flows related to certain airport construction projects and other and (iv) financed aircraft acquisitions. These adjustments are made for the following reasons:

Net redemptions of short-term investments. Net redemptions of short-term investments represent the net purchase and sale activity of investments and marketable securities in the period, including gains and losses. We adjust for this activity to provide investors a better understanding of the company's free cash flow generated by our operations.

Strategic investments and related. Certain cash flows related to our investments in and related transactions with other airlines and associated companies, including Wheels Up in the September 2023 quarter, are included in our GAAP investing activities. We adjust for this activity because it provides a more meaningful comparison to our airline industry peers.

Net cash flows related to certain airport construction projects and other. Cash flows related to certain airport construction projects are included in our GAAP operating activities and capital expenditures. We have adjusted for these items, which were primarily funded by cash restricted for airport construction, to provide investors a better understanding of the company's free cash flow and capital expenditures that are core to our operations in the periods shown.

Financed aircraft acquisitions. This adjustment reflects aircraft deliveries that are leased as capital expenditures. The adjustment is based on their original contractual purchase price or an estimate of the aircraft's fair value and provides a more meaningful view of our investing activities.
