Major U.S. Airlines Favor Higher Fares Over Fuller Planes

An empty seat doesn’t necessarily mean an airline is ready to offer you a deal. Major U.S. carriers are choosing higher ticket prices over fuller planes as soaring jet fuel costs put pressure on profits, according to Fortune.

The price jump is substantial: U.S. airfares were 22.4% higher in September than a year earlier, Fortune reported, citing the Bureau of Labor Statistics’ consumer price index. Overall inflation was 3.7%.

The strategy is bringing in more money. Delta Air Lines, United Airlines, American Airlines, Southwest Airlines and Alaska Air Group collectively generated nearly $8.8 billion more passenger revenue in Q3 2026 than in Q3 2025, an 18% increase, Fortune reported, citing Reuters. Passenger traffic grew less than 1%.

But there’s a catch for the airlines, and little comfort for travelers paying those fares: more revenue hasn’t been enough to keep rising fuel costs from squeezing profits.

Why airlines are accepting emptier seats

Airlines have long balanced ticket prices against the number of seats they can sell. The current approach puts more weight on what each passenger pays, rather than filling the cabin through discounts, according to Reuters’ analysis published by the Miami Herald.

Two industry terms explain the trade-off. Load factor measures how much of an aircraft’s available seating is occupied. Yield is the revenue an airline collects for each mile passengers fly, Reuters explained. Airlines are increasingly willing to accept a lower load factor if higher yields make the flying more financially worthwhile.

“If fuel stays elevated, we have to continue to push yield up so that we can make a bit of money,” said Devon May, chief financial officer at American Airlines, according to Fortune, citing his comments to Reuters.

It isn’t simply a matter of charging more for the same mix of tickets. Reuters reported that premium products and changes in passenger mix also contributed to the revenue gains. The combined passenger-revenue increase therefore shouldn’t be read as a direct measure of how much more every traveler paid.

American, United and Southwest show the trade-off

American reported record Q3 revenue of $16.3 billion, according to Fortune. Its chief commercial officer, Nathaniel Pieper, said the airline deliberately accepted lower seat occupancy in exchange for higher passenger yields. Reuters added that American’s passenger yields jumped more than 18% while its planes flew less full.

United made a similar calculation. Its leisure load factor declined 1.3 percentage points in Q3, Fortune reported. Chief commercial officer Andrew Nocella acknowledged that higher ticket prices had prompted some sensitivity among travelers, but United considered the exchange worthwhile.

Southwest’s fare increases were particularly pronounced. According to Fortune, its average passenger fare rose 21.6% in the first nine months of the year, with the third-quarter increase reaching 26.9%.

Those results point to a distinction worth keeping in mind when shopping: airlines can be pleased with their pricing even when their planes aren’t as full. A softer occupancy figure, on its own, doesn’t establish that a carrier is preparing to cut fares.

Jet fuel is consuming the revenue gains

The cost pressure behind the strategy is steep. Gulf Coast spot jet fuel prices rose from $2.43 per gallon before the war with Iran began in February to $4.63 in October, Fortune reported, citing U.S. Energy Information Administration data. Fortune described that as an increase of roughly 91%, driven mainly by disruptions to oil supplies and refining capacity associated with the conflict.

Fuel is also taking a larger share of airline spending. The International Air Transport Association projects that it will account for nearly one-third of airline operating expenses in 2026, compared with about one-quarter in 2025, according to Fortune.

Timing makes recovering that expense harder. Airlines typically sell tickets months before departure and cannot raise the price of seats passengers have already purchased, Fortune explained. That leaves unsold tickets as the opportunity to collect higher fares as costs rise.

Even then, the extra revenue doesn’t necessarily preserve earnings. Delta cut its annual earnings forecast and expects roughly $4.5 billion in pre-tax profit while absorbing a $6 billion increase in fuel costs, Fortune reported. Reuters reported that Southwest also cut its annual earnings forecast, while American expects a full-year loss despite sharply higher passenger revenue.

Holiday travelers are already facing higher fares

For anyone still pricing a holiday trip, the pressure isn’t confined to airline earnings reports. Thanksgiving airfares are up about 30% compared with last year, while Christmas tickets are up more than 20%, according to Hopper lead economist Hayley Berg in NPR reporting published by Texas Public Radio.

Berg said travelers were shopping around more and booking earlier to secure reasonable prices. Hopper had already seen an increase in customers booking holiday travel in September, according to that report. Berg also said travelers were unlikely to make major changes to traditional holiday trips despite higher prices.

Fare increases were still being attempted beyond the quarterly results. Reuters reported that JetBlue initiated a $10 one-way increase in domestic published fares during the week of its Oct. 23 report, citing JP Morgan. That followed a similar United-led increase the previous week that Southwest subsequently matched.

Will more flights bring price relief?

More capacity could test the strategy, but the schedules aren’t guarantees. Reuters reported that six major U.S. airlines planned year-over-year domestic capacity growth of 3.0% in the fourth quarter and 3.8% in the first quarter of 2027, compared with 0.2% in the third quarter, citing Airlines for America and Cirium data.

At the same time, American intends to slow growth considerably next year, and United executives cautioned that published 2027 capacity plans may not materialize, Reuters reported.

For travelers, the important shift is straightforward: these carriers are willing to leave seats empty rather than discount simply to fill them. Waiting for a less-full plane to produce a bargain looks like a shaky assumption when the airline is explicitly choosing higher fares over higher occupancy.
