NEW YORK, August 4, 2026, 10:08 EDT (U.S. markets open)
- American shares rose 2.2% to $16.39, extending Monday’s 5% increase.
- Brent crude declined 4.7% to $79.82, weighed down by diplomatic optimism.
- For American, each 10-cent shift in annual fuel prices amounts to around $450 million.
American Airlines shares climbed 2.2% on Tuesday morning, marking a two-day advance of approximately 7.3%. Airlines benefited from declining oil prices after diplomatic remarks fueled optimism about increased passage through the Strait of Hormuz.
From an investor perspective, American’s earnings margin is notably thin. According to the airline, every one-cent shift in yearly fuel costs impacts expenses by around $45 million.
A consistent drop of 10 cents would cut yearly costs by about $450 million. This figure is close to American’s total operating profit of $446 million for the second quarter.
Airline shares made broad gains soon after the market opened. American and United led the way over Delta, but each of the three stocks moved up.
| Company | Price at 09:53 EDT | Tuesday move | Intraday range | Market value |
|---|---|---|---|---|
| American Airlines Group Inc. NASDAQ:AAL | $16.39 | up 2.2% | $15.94–$16.76 | $10.9 billion |
| Delta Air Lines Inc. NYSE:DAL | $92.78 | rising 1.3% | $91.13–$94.25 | $61.0 billion |
| United Airlines Holdings Inc. NASDAQ:UAL | $131.51 | adding 2.4% | $127.43–$133.54 | $42.7 billion |
American held the lowest operating margin of the three major U.S. network airlines as it moved into the oil reversal, reporting a GAAP margin of 2.7% for the second quarter. By comparison, Delta posted a margin of 9.4%, while United reported 6.2%.
| Second-quarter 2026 GAAP results | Revenue | Operating profit | Operating margin |
|---|---|---|---|
| American | $16.74 billion | $446 million | 2.7% |
| Delta | $19.76 billion | $1.86 billion | 9.4% |
| United | $17.67 billion | $1.10 billion | 6.2% |
American reported a 16.3% rise in revenue compared with the previous year. Fuel costs surged 83.3% to $4.88 billion. Operating income dropped 60.7%.
The numbers show the significance of Tuesday’s crude reversal. Despite record revenue, American had less insulation from fuel price swings compared to its main competitors.
Brent dropped to its lowest level in three weeks following remarks by Qatar and U.S. Treasury Secretary Scott Bessent that boosted optimism over diplomatic efforts. UBS Group AG NYSE:UBS analyst Giovanni Staunovo referenced reports stating that “a potential U.S.-Iran resolution has been drafted.” Reuters
The airlines’ current outlooks remain based on differing fuel assumptions and calculation timing, making them not directly comparable.
| Current guidance | Q3 fuel assumption | Q3 adjusted EPS | Full-year adjusted EPS |
|---|---|---|---|
| American | Roughly $3.75 per gallon | Negative $0.70 to negative $0.10 | Negative $0.65 to positive $0.65 |
| Delta | Approximately $3.15 per gallon | $2.00 to $2.50 | $6.50 to $7.50 |
| United | Roughly $3.69 per gallon | $2.50 to $3.50 | $9.00 to $11.00 |
American relied on the July 21 forward curve for its projections. Delta factored in July 2 data and a five-cent refinery benefit, whereas United referenced July 14. The drop in crude prices on Tuesday will not result in an exact equivalent drop in jet-fuel costs.
Nonetheless, American’s revealed sensitivity underlines the possible magnitude. The preliminary math below uses the carrier’s $45 million-per-point figure against its $10.9 billion market capitalization on Tuesday.
| Annual fuel price movement | Estimated effect on pretax costs | Portion of market value |
|---|---|---|
| 1 cent for each gallon | $45 million | 0.4% |
| 10 cents for each gallon | $450 million | 4.1% |
| 25 cents for each gallon | $1.13 billion | 10.3% |
| 50 cents for each gallon | $2.25 billion | 20.7% |
The figures shown are illustrative annualized values and do not represent profit forecasts. They do not include fare recovery, taxes, fuel-basis fluctuations or changes in flight activity.
American reported notable gains in revenue drivers. Premium passenger unit revenue climbed 13.4%, while managed corporate revenue advanced 26%.
AAdvantage sign-ups rose over 30% during the second quarter, while expenditure via the co-branded credit card partnership climbed 8%.
The increase has not entirely offset the impact of higher fuel costs. Chief Financial Officer Devon May noted the anticipated recovery rate was “obviously not 100%” after the forecast for second-half fuel expenses climbed by almost $1.6 billion. Reuters
Risks: Diplomatic challenges have the potential to swiftly halt oil’s drop. Jet fuel prices may move independently from crude, and ongoing fare hikes risk curbing demand. American’s slimmer margin offers little buffer against unexpected events.
The rally on Tuesday points to possible cost easing, but the company’s earnings outlook remains unchanged. American continues to project full-year results between a 65-cent loss and a 65-cent gain, keeping breakeven as the midpoint.
