Financial Guidance¹

Revenue Environment and Outlook

"Delta generated record September quarter revenue of $15.2 billion, up 4.1 percent year-over-year, reflecting the strength of our diverse, high margin revenue streams and improving Domestic fundamentals.  Over the last 6 weeks, sales trends have accelerated across all geographies and in every advance purchase window, positioning Delta to finish the year with momentum.  For the December quarter, we expect total revenue growth of 2 percent to 4 percent over last year's record performance, with healthy sequential unit revenue improvement driven by continued Domestic strength and meaningful improvement in Transatlantic unit revenue," said Glen Hauenstein, Delta's president.

• Record September quarter revenue reflecting the strength of Delta's brand: September quarter total revenue increased 4.1 percent over prior year to a record $15.2 billion, led by premium, corporate and loyalty.  Adjusted total unit revenue (TRASM) growth improved 3.5 points sequentially, with the September quarter up 0.3 percent over prior year.  Consistent with previous disclosures, year-over-year comparisons for the September quarter benefitted from lapping last year's CrowdStrike-caused outage, including 2.6 points on total revenue growth and 1.1 points on total unit revenue growth.  The December quarter outlook for revenue growth of 2 percent to 4 percent reflects healthy sequential improvement in underlying revenue and unit revenue trends.
• Diverse, high-margin revenue streams leading growth: Delta's diversified revenue base contributed 60 percent of total revenue in the third quarter and grew double-digits year-over-year.  Premium revenue grew 9 percent compared to the September quarter of 2024, with improvement across all products.  Loyalty revenue increased 9 percent year-over-year as SkyMiles members continue to deepen engagement beyond flight.  American Express remuneration of $2 billion grew 12 percent over prior year, driven by double-digit co-brand spend growth.
• Improving Domestic revenue environment: Domestic passenger revenue grew 5 percent year-over-year, supported by an acceleration in corporate sales, continued strength in premium cabins and an inflection in main cabin unit revenue growth.  Domestic unit revenue grew 2 percent over prior year during the quarter and is expected to remain positive in the December quarter.
• Corporate sales* rebounding with sequential improvement across all sectors: Corporate sales were up 8 percent over prior year in the third quarter.  Recent corporate survey results indicate that roughly 90 percent of companies expect their travel volume to increase or remain steady in 2026, 5 points higher than last year's survey at this time.

Cost Performance and Outlook

"Our teams continue to deliver for our customers, achieving operational performance that has led the industry.  Non-fuel unit cost growth was approximately flat compared to prior year, bringing year-to-date non-fuel unit cost growth to less than 2 percent, consistent with our low-single digit guidance at the start of the year even as we reduced capacity post summer to align to demand," said Dan Janki, Delta's chief financial officer.

September Quarter 2025 Cost Performance

• Operating expense of $15.0 billion and adjusted operating expense of $13.5 billion
• Adjusted non-fuel costs of $10.6 billion
• Non-fuel CASM was 13.35¢, an increase of 0.3 percent year-over-year
• Adjusted fuel expense of $2.6 billion was down 8 percent year-over-year
• Adjusted fuel price of $2.25 per gallon decreased 11 percent year-over-year with a refinery benefit of 5¢ per gallon

Balance Sheet, Cash and Liquidity

"With strong cash generation through the year, we have paid down nearly $2 billion in debt year-to-date, bringing gross leverage to 2.4x at the end of the quarter," Janki said.  "For the full year, we expect free cash flow of $3.5 to $4 billion.  This outlook is within our long-term target range and enables us to pay down debt while continuing to reinvest in the business and return cash to shareholders."

• Adjusted net debt of $15.6 billion at September quarter end, a reduction of $2.4 billion from the end of 2024
• Payments on debt and finance lease obligations for the September quarter of $459 million
• Weighted average interest rate of 4.5 percent with 95 percent fixed rate debt and 5 percent variable rate debt

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. 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.

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.

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.

Realized gain on sale of investments. This adjustment relates to gains on the sale of investments generated in adjusted results that had previously been included in GAAP results. During the September 2024 quarter, we sold a portion of our investment in CLEAR. Adjusting for this gain allows investors to better understand and analyze our core operational performance in the periods shown.

 

 

 

 

 

Operating Cash Flow, adjusted. We present operating cash flow, adjusted because management believes adjusting for the following item 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 adjust 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 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.

 

 

 

 

Adjusted Debt to Earnings Before Interest, Taxes, Depreciation, Amortization and Rent ("EBITDAR"). We present adjusted debt to EBITDAR ("gross leverage") because management believes this metric is helpful to investors in assessing the company's overall debt profile. Adjusted debt includes total operating lease liabilities (including fleet, ground and other) and sale-leaseback financing liabilities. We calculate EBITDAR by adding depreciation and amortization to operating income, adjusted and adjusting for the fixed portion of operating lease expense.

 

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.

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

Net cash flows related to certain airport construction projects. Cash flows related to certain airport construction projects are included in capital expenditures. We adjust 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 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 (iii) net redemptions of short-term investments. 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.

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.
