Delta Air Lines — Financial Results
Premium Cabin Demand Is Carrying Revenue Growth While Main Cabin Softens
| Segment | 2025 Revenue | 2024 Revenue | Change |
|---|---|---|---|
| Main cabin tickets | $23,391M | $24,497M | -5% |
| Premium product tickets | $22,097M | $20,599M | +7% |
| Total passenger revenue | $51,768M | $50,894M | +2% |
Demand for premium seats — think business class and upgraded economy — grew 7%, while standard main cabin revenue fell 5%. Delta attributes the main cabin weakness to industry-wide oversupply in a uncertain economic environment. The gap between these two trends is worth watching: Delta is deliberately configuring new aircraft with more premium seats, which suggests this is a strategic bet, not just a lucky trend.
The American Express Partnership Is a Quietly Enormous Business
Remuneration from American Express — payments Delta receives for selling miles to Amex, which then rewards cardholders — hit $8.2 billion in 2025, up 11% from 2024. Total cash sales from all loyalty marketing agreements were $8.0 billion. This loyalty revenue stream is remarkably stable compared to ticket sales and is growing double digits, making it one of the most valuable parts of the business.
Rising Labor Costs Are the Biggest Expense Pressure
| Cost Item | 2025 | 2024 | Change |
|---|---|---|---|
| Salaries and related costs | $17,520M | $16,161M | +8% |
| Aircraft fuel | $9,819M | $10,566M | -7% |
Wages rose 8% following pay increases of 4–5% for most employees and 4% for pilots. Falling jet fuel costs (down 7%, or $747 million) partially cushioned the blow. The net result was that costs grew slightly faster than revenue, trimming operating income (profit from running the airline) by $173 million to $5.8 billion.
Delta Is Aggressively Paying Down Debt and Earning Investment-Grade Status
Delta repaid $4.8 billion in debt and lease obligations during 2025 — including $2.9 billion in early repayments — and refinanced higher-cost loans at lower rates. The total debt balance stood at $14.1 billion at year-end. Moody's upgraded Delta to investment grade (Baa2) in February 2025, and both Fitch and S&P shifted their outlooks to Positive. Investment-grade status typically means lower borrowing costs going forward.
Strong Cash Generation Is Funding Both Debt Repayment and Fleet Expansion
Delta generated $8.3 billion from operations and $4.6 billion in free cash flow (cash left after capital spending, adjusted for certain items) in 2025. The company is simultaneously reducing debt and committing to roughly $5.5 billion in capital spending in 2026, primarily for new aircraft. In early 2026, Delta signed deals to acquire up to 60 Boeing 787-10s (deliveries from 2031) and up to 51 Airbus widebody jets (deliveries from 2029), signaling a significant long-term fleet renewal.
