Q3 2026 U.S. airlines’ earnings

• Corporate and premium travel led the quarter. Every airline reported double-digit growth or record results in its managed or contracted business, and premium revenue rose between 17 and 23 percent at Delta, United and American.
  
  
• Fares rose sharply. Average yield, the price paid for each mile flown, was up between 14 and 23 percent across the four carriers. All have said they intend to keep fares high to recover fuel costs.
  
  
• Since the pandemic, fuel surcharges have grown from less than 10 percent of the total ticket price to close to 20 percent, passing more of the fuel risk on to customers.
  
  
• All four airlines cut their 2026 earnings outlook and expect revenue to keep growing strongly in the fourth quarter.

Third-quarter earnings showed the four largest U.S. airlines generating record revenue from higher fares, while rising fuel costs continued to erode profitability. Delta Air Lines retained its lead on revenue quality, while United Airlines reported the highest GAAP net income. Southwest Airlines continued to improve its margins, and American Airlines grew its corporate and premium business strongly but returned to a loss.

Fuel again dominated every earnings announcement. Jet fuel prices were more than 60 percent higher than a year earlier, adding $1.9 billion to American’s costs, about $1.8 billion each at United and Delta and $821 million at Southwest. In terms of GAAP net income, United earned $1.03 billion, Delta $756 million and Southwest $270 million, while American lost $269 million. However, one-off items can distort these figures. United’s result included $215 million of special credits, mostly sale-leaseback gains, and Delta’s was reduced by $218 million of losses on its equity investments. On an adjusted basis, Delta earned about $1.13 billion and United $833 million.

Most of the revenue growth came with little or no extra flying. Delta grew adjusted revenue 16 percent on flat capacity, United grew revenue 17.4 percent on 1.3 percent more capacity, and Southwest grew revenue 21.2 percent with capacity down 0.4 percent. American took a different approach, growing capacity 4.2 percent while its load factor fell 2.6 points.

For corporate buyers, fourth-quarter guidance points to higher fares. Between October and December, Delta expects revenue to grow about 20 percent, United more than 20 percent and American 19.5 to 22.5 percent. Southwest guides on unit revenue, which it expects to rise 19 to 21 percent on 3 to 4 percent more capacity.

Takeaways

Delta kept its lead on revenue quality. It again produced the highest unit revenue, the highest load factor and, on an adjusted basis, the strongest operating margin at 9.4 percent. Premium revenue grew 18 percent on 6 percent more seats, and corporate sales grew by double digits in every sector, led by banking, technology and energy. GAAP net income fell 47 percent because of fuel and investment losses. Delta also reported the lowest fuel price of the four, at $3.61 a gallon on an adjusted basis, about 7 percent below the average of the other three airlines. Its GAAP fuel price of $3.80 was much closer to its rivals.

United delivered the highest headline profit. Revenue rose 17.4 percent to $17.9 billion, contracted business revenue grew 26 percent and premium revenue grew 17 percent. Its GAAP operating margin was 8.1 percent, and its adjusted operating margin, which excludes $215 million of net special credits made up mostly of sale-leaseback gains, was 6.9 percent. It had the lowest non-fuel unit cost of the three network carriers, at 13.09 cents. Its unit revenue of 20.19 cents was the lowest of the three, just behind American and well behind Delta, which makes growing revenue, and corporate revenue in particular, its biggest opportunity. Its renewed Sabre agreement should help it reach more corporate customers by making a broader range of United fares available through travel agencies. United recovered 72 percent of its higher fuel bill through revenue, short of the 80 to 90 percent it forecast in July.

Southwest continued to improve. Revenue rose 21.2 percent and net income increased from $54 million to $270 million, with the operating margin up 4 points to 4.5 percent. Managed business revenue set a third-quarter record, and the airline added NDC connectivity and a Business Priority product for corporate customers. It carried 3.2 percent fewer revenue passengers, as its average fare rose almost 27 percent.

American’s commercial recovery continued, but it returned to a loss. Managed corporate revenue grew 27.6 percent, the sixth consecutive quarter of double-digit growth, and premium revenue grew 22.9 percent. After reporting a $71 million profit in the second quarter, American recorded a $269 million loss in Q3.

The American conundrum. The DFW-headquartered airline’s problems run deeper than fuel. Domestic flying produced about 70 percent of its passenger revenue, and it has fewer widebody aircraft than its rivals, with 137 at the end of 2025 against 158 at Delta and 230 at United. That limits its growth in international markets, where its unit revenue rose 16.4 percent against 13.6 percent at home. To meet its heavy domestic schedule, it flies its aircraft hard and turns them around quickly, which adds to its maintenance bill. Maintenance costs rose 6.2 percent to $1.09 billion, and its non-fuel unit cost of 14.34 cents is the highest of the three network carriers.

American carries $29.6 billion of debt and finance leases, the most of the four, which makes the new widebodies that would break the cycle harder to pay for, and the extra maintenance uses up more of the cash it has. Earlier this year, it was reported that the airline had asked Boeing and Airbus to bid for a large widebody order, reportedly of 50 to 70 aircraft, and expects to make a decision this year. Deliveries are reported to start around 2030, so the gap with Delta and United will take years to close.

Fuel exposed the underlying strength of each airline again. Delta and United had enough margin to absorb the higher fuel bill and stay profitable, and Southwest grew its earnings with it. American’s thin margin pushed it into a loss, and it now expects a full-year adjusted loss of $1.00 to $1.60 per share.

Fares are set to keep rising into 2027. Fourth-quarter fuel assumptions range from about $4.25 per gallon at Delta to about $4.80 at United, well above third-quarter prices. United said it expects to recover the full increase through fares, with a lag. Capacity plans differ. Delta expects seats to grow less than 2 percent in the fourth quarter, American plans growth of 5.5 to 6.5 percent and United expects industry capacity to increase through 2027. The question is how much further fares can rise before travelers trade down to cheaper tickets or companies cut back on trips.

In short

Delta produced the strongest underlying result and remains the benchmark for revenue quality, load factor, premium travel and loyalty.

United reported the highest GAAP profit and, on an adjusted basis, held a strong second place, with corporate demand and pricing supporting another profitable quarter.

Southwest showed again that its commercial overhaul is paying off, and it is becoming a more serious option for domestic corporate travel. Its 4.5 percent operating margin is still well below Delta’s 7.2 percent and United’s 8.1 percent, which shows how far it has to go in winning premium and corporate business from the two leaders.

American posted strong commercial numbers and the weakest margin of the four. It is adding capacity faster than its rivals while losing money, which leaves it the most exposed if fuel stays high.

Higher fuel costs contributed to weaker earnings across the industry, but they do not fully explain the differences in profitability. Those differences reflect investment choices made over many years, and American has fallen further behind since the second quarter.

Airline comparison (Q3 2026)

Revenue per available seat mile (RASM) figures are based on the metrics reported by each airline. Delta’s adjusted figures exclude third-party refinery sales and certain other adjustments. Other figures are reported on a GAAP basis unless identified as adjusted.

Revenue quality and cost 

Comparing reported revenue per available seat mile (RASM) with cost per available seat mile (CASM) gives a simple view of how efficiently each airline converted capacity into revenue relative to its operating costs. It is a useful indicator of commercial performance and should be read alongside the operating margins above.

Delta again produced the widest revenue-cost spread, up from about 1.99 cents in the second quarter. United’s spread grew to 1.63 cents, helped by special credits that lowered its unit costs by 0.24 cents. Southwest’s spread rose to 0.83 cents. American’s narrowed from about 0.55 cents to 0.15 cents, leaving very little to cover a quarterly interest bill of $435 million.

What buyers should watch in Q4 2026 and into 2027

• How much of the fare increases behind this quarter’s revenue growth will carry into 2027 corporate fares?
• If fuel prices fall, will airlines pass the savings back to customers or treat today’s fares as the new baseline?
• Will industry capacity growth in 2027 give buyers more negotiating room, or will airlines cut schedules to protect yields?
• Given its debt and weak profits, will American have the money to grow its international network and keep improving its product?
• Will Southwest’s NDC connectivity and Business Priority product win it a larger share of managed travel programs?
• How much of the growth in corporate revenue reflects higher fares and premium purchases, and how much reflects more trips?
• Will Delta’s refinery provide meaningful protection if fuel stays above $4 a gallon, after an outage left it with an operating loss this quarter?
