ATLANTA, October 9, 2026 – Delta Air Lines (NYSE: DAL) today reported financial results for the September quarter and provided its outlook for the December quarter and full year 2026. Highlights of the September quarter, including both GAAP and adjusted metrics, are on page five and incorporated here.

“Demand remains strong, supported by consumers’ growing preference for experiences and travel, with air travel continuing to be one of the best values in the consumer economy. Against this backdrop, we delivered September quarter pre-tax profit of $1.5 billion, matching last year's performance, and generated $1.9 billion of free cash flow year-to-date. Our resilience reflects the structural durability we’ve built over many years, enabling us to effectively navigate one of the most elevated fuel environments in recent times. The foundation of that resilience is our people, whose commitment to delivering for our customers continues to set Delta apart," said Ed Bastian, Delta’s chief executive officer.

"For the full year, we expect to generate a pre-tax profit of roughly $4.5 billion, absorbing a $6 billion increase in fuel costs. Looking ahead, our focus remains on profitable growth and delivering against our long-term financial framework, including mid-teens margins and returns, durable free cash flow and gross leverage of approximately one times."

Guidance for the December quarter assumes fuel at the forward curve as of October 2, 2026, and includes a refinery benefit of approximately $0.40 per gallon. This results in a projected all-in fuel price for the quarter of approximately $4.25 per gallon.



Revenue Environment and Outlook

"September quarter revenue grew approximately 16 percent over prior year, on flat capacity, driven by broad demand strength and healthy yield growth as we cover higher costs and manage the business for margins,” said Joe Esposito, Delta’s chief commercial officer.

“Revenue momentum is continuing in the December quarter, with strength across all products and geographies, supporting our outlook for total revenue growth of approximately 20 percent over last year. With seats growing less than 2 percent, including a reduction in Main Cabin seats, our capacity positioning supports another quarter of sequential improvement in unit revenue with progression in both Domestic and International.”

•Broad demand strength continued in the September quarter: Delta delivered record September quarter total revenue of $17.6 billion, increasing 16 percent over the same period last year. Adjusted total unit revenue (TRASM) grew 15 percent over prior year, accelerating 3 points from the prior quarter. Main cabin unit revenue grew 17 percent over prior year on seats down low-single digits, marking another quarter of sequential progress.
•Strong revenue performance across all geographies: Domestic unit revenue grew 16 percent year-over-year on strong yields and a load factor that was 1 point higher than last year, reflecting the strength of Delta's brand and a measured approach to capacity. International unit revenue increased 12 percent, with performance led by Latin where unit revenue improved 22 percent over last year. Transatlantic unit revenue growth improved 4 points sequentially to 11 percent year-over-year. Transpacific revenue grew 13 percent over prior year on 8 percent higher capacity, supporting profitable growth through new routes to Asia.
•Continued momentum in diversified, high-margin revenue streams: Diverse revenue streams accounted for 61 percent of total revenue in the September quarter. Premium revenue grew 18 percent year-over-year with double-digit unit revenue growth driven by yield and load factor on a 6 percent increase in seats. Cargo revenue increased 29 percent year-over-year, with roughly equal growth between volume and yield. MRO revenue grew 28 percent year-over-year, bringing year-to-date revenue to $990 million.
•Growing member engagement across loyalty ecosystem: Total loyalty revenue grew 18 percent, with SkyMiles member engagement continuing to deepen in the air and beyond the flight. Co-brand card acquisitions and spend both grew double-digits, the eighth consecutive quarter of double-digit growth in cardholder spend. This momentum supported 15 percent growth in American Express remuneration in the quarter, positioning the full year to exceed $9 billion. Travel products and non-air partnership revenue increased 25 percent year-over-year.
•Corporate sales3 grew double-digits in all sectors: Corporate sales growth was led by the Banking, Technology, and Energy sectors, with particularly strong performance in Boston and Los Angeles. Recent corporate survey results indicate over 90 percent of respondents expect their corporate travel will increase or stay the same in 2027.

Cost Performance and Outlook

"Delta delivered earnings of $1.72 per share in the September quarter, in line with last year while absorbing more than $500 million of higher fuel costs compared to our guidance in early July. In the December quarter, we expect earnings of $1.15 to $1.65 per share, based on a fuel price of approximately $4.25 per gallon. This positions earnings consistent with last year at the upper end of the range," said Erik Snell, Delta’s chief financial officer.

"The Delta team continues to deliver for our customers, widening our industry lead in on-time performance and achieving record baggage results. September quarter non-fuel unit costs increased 7.3 percent over the prior year on flat capacity, driven primarily by higher crew and revenue-related costs on capacity growth that was several points below our original plan, including nearly one point of impact from summer storms. With slightly higher capacity and continued operational efficiencies, we expect December quarter non-fuel unit cost growth to improve 1 to 2 points sequentially. Looking to next year, we remain on track for low-single-digit unit cost growth as capacity normalizes, operational improvements continue and we lap higher costs in our baseline."

September Quarter 2026 Cost Performance

•Operating expense of $18.7 billion and adjusted operating expense of $15.9 billion
•Adjusted non-fuel costs of $11.1 billion
•Non-fuel CASM was 14.03¢, an increase of 7.3 percent year-over-year
•Adjusted fuel expense of $4.1 billion was up 62 percent year-over-year
•Adjusted fuel price of $3.61 per gallon increased 60 percent year-over-year with a refinery benefit of 13¢ per gallon
•Fuel efficiency, defined as gallons per 1,000 ASMs, was 14.5

Balance Sheet, Cash and Liquidity

"We generated $463 million of free cash flow in the September quarter. The strength of our cash flow generation allows us to consistently reinvest to compound our advantages while reinforcing our investment grade balance sheet. For the full year, we expect to deliver free cash flow of approximately $2.5 billion and pay down more than $2 billion of debt, positioning us to end the year with gross leverage of approximately 2.2x,” Snell said.

•Adjusted net debt of $13.4 billion at September quarter end, a reduction of $950 million from the end of 2025
•Payments on debt and finance lease obligations for the September quarter of $1.2 billion
•Adjusted operating cash flow in the September quarter of $1.7 billion, and with gross capital expenditures of $1.4 billion, free cash flow was $463 million
•Air Traffic Liability ended the quarter at $9.6 billion
•Liquidity1 of $6.9 billion at quarter-end, including $3.1 billion in undrawn revolver capacity

1 Includes cash and cash equivalents, short-term investments and undrawn revolving credit facilities

Exhibit 99.1

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 exactly 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. MTM 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 closed (i.e., settled) during the applicable period. With respect to hedges related to Monroe's inventory, settlements often occur before the related refinery inventory is sold. Beginning in 2026, settlement gains and losses related to Monroe's inventory that remains on-hand at period end are excluded from our adjusted results. These settlement gains and losses will be reflected in adjusted results during the period the inventory is sold. This change was made to match the timing of expense and revenue recognition and we have similarly adjusted the presentation of reconciliations for prior periods included here.

MTM adjustments on investments. Unrealized MTM 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.

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

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 incentive compensation programs. Free cash flow is defined as net cash from operating activities and net cash from investing activities, adjusted for (i) pension plan contributions, (ii) net cash flows related to certain airport construction projects and other, and (iii) strategic investments and related. These adjustments are made for the following reasons:

Pension plan contributions. Cash flows related to pension funding are included in our GAAP operating activities. We adjust to exclude these contributions to allow investors to understand the cash flows related to our core operations.

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.

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

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.

MRO expense. We adjust for MRO expenses because this adjustment allows investors to better understand and analyze the airline's recurring cost performance and provides a more meaningful comparison of our core operating costs to the airline industry.

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.

Adjusted Net Debt. We use adjusted gross debt, including fleet operating lease liabilities (comprised of aircraft and engine leases and regional aircraft leases embedded within our capacity purchase agreements) and unfunded pension liabilities (if applicable), in addition to adjusted debt and finance leases, to present estimated financial obligations. We reduce adjusted total debt by cash, cash equivalents, 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.
