Airline earnings for Q3 2026: Delta, United and Southwest stayed profitable, American and Alaska lost money. Record revenue at four of them — and fuel up over 60%.
US airlines just booked record summer revenue — and two of the biggest still lost money. That is the strange headline from the third-quarter 2026 earnings season, the results covering July to September. Revenue hit records almost everywhere. Then the fuel bill arrived. Here is a plain-language roundup of who made a profit, who didn’t, and why.
People kept flying and paying more, but jet fuel cost around 60% more than a year earlier, and that ate most of the gain.
The cause is the oil shock that followed the conflict in the Middle East this year, which we covered when IATA halved its 2026 profit forecast. Q3 is the peak summer quarter. The five big US airlines below paid between $3.80 and $3.94 a gallon for fuel in the quarter; a year ago, United and Southwest were paying about $2.40.
When a cost that is roughly a quarter of your spending (23% of Delta’s operating expense this quarter) jumps by two-thirds, a 20% rise in revenue isn’t enough. That is the whole quarter in one chart.
Delta stayed solidly profitable. Revenue rose 21% to $20.2 billion, a record for the September quarter, and it earned $756 million — but that’s down from $1.4 billion last year, and its fuel bill was up 69% to $4.35 billion. Delta cut its full-year profit forecast to $5.10–$5.60 per share, from $6.50–$7.50 in July, saying it will absorb a $6 billion rise in fuel costs this year. Chief executive Ed Bastian’s explanation of why revenue held up: “Demand remains strong, supported by consumers’ growing preference for experiences and travel.”
United earned $1.0 billion on record revenue of $17.9 billion (up 17.4%), with premium revenue up 17%. Fuel cost $4.8 billion, up 61.6%. United expects another revenue record in the fourth quarter.
Southwest had the most interesting quarter. It made $270 million, up from $54 million a year ago, on record revenue of $8.4 billion (up 21.2%) — while flying slightly less (capacity down 0.4%). Its revenue per seat-mile, the airline industry’s standard measure of how much it earns from each seat it flies one mile, rose a record 21.6%. Chief executive Bob Jordan said demand stayed strong even as Southwest lapped last year’s bag fee and other commercial changes. It has trimmed its full-year capacity growth to about 1.2%, from about 1.5%.
American reported a record $16.3 billion in revenue, up 19.3% — and a $269 million net loss. Its fuel bill rose 67.5% to $4.6 billion. Chief executive Robert Isom called it “the strongest year-over-year revenue growth in my career,” but American now expects a loss for the full year. Unlike Delta and Southwest this quarter, it kept growing capacity — up 4.2% in Q3, with 5.5–6.5% planned for Q4.
Alaska Air Group lost $147 million, against a profit a year earlier, even as revenue rose 14% to $4.3 billion. Fuel came in at $3.94 a gallon, above the $3.75 it had expected, and the airline puts this year’s fuel headwind at $1.8 billion.
Three things separate the winners from the strugglers this quarter:
Fuel isn’t easing yet. Airlines are guiding fourth-quarter fuel prices higher still — for example about $4.70 a gallon at American, $4.55 at Southwest and $4.65–$4.85 at Alaska. Demand, though, still looks strong: Delta expects Q4 revenue up about 20%, and United expects growth above 20%.
Outside the US, Europe’s big airline groups — IAG, Lufthansa Group and Air France-KLM — report on their own calendars. Their summer results will show how much fuel hedging (buying fuel in advance at fixed prices) has protected them.
The lesson of Q3 is the one from our look at 2026’s capacity squeeze: when costs are out of your hands, the airline that decides where and how much to fly most carefully keeps more of its money. Those decisions live in the schedule — the thing SSIM Toolkit helps teams read, compare and check.
Figures are from each airline’s Q3 2026 earnings release (Alaska’s as reported by the Anchorage Daily News); “net income” is GAAP. Fuel prices are the airlines’ reported average cost per gallon, and fourth-quarter numbers are company guidance, not results.

IATA now sees 2026 industry net profit at $23B — roughly half of last year — as jet fuel jumps from $90 to $152 a barrel. Demand is still strong and carriers are beating estimates. For investors, the gap between the two is the whole story.
Airline stocks turn on unit revenue and unit cost — RASM and CASM per available seat mile. In 2026, carriers are posting double-digit RASM growth on ~1% more capacity. The denominator under every one of those metrics is the schedule.
While Farnborough fills with orders for jets that arrive in the 2030s, the global fleet has quietly aged to a record ~15 years. Retirements are deferred, the installed base is where the money is, and the schedule is where an aging fleet is won or lost.
