The number of passengers screened at US airport checkpoints is heading for its first year-on-year decline since 2020, yet major carriers say they are comfortable with that, preferring to capture higher fares than fill every seat.
American Airlines' load factor, a measure of how full its planes fly, fell to 83.4% in the third quarter from 86% a year earlier. "We're actively prioritizing yield versus load factor and really happy as we see it. It fits right in with the premium investments that we're making," American's chief commercial officer, Nat Pieper, said on the company's earnings call.
Fares keep climbing
Ticket prices have climbed sharply as airlines pass on higher jet fuel costs, their biggest expense after labour. September fares were up more than 22% from a year earlier, and fare tracker Hopper expects this holiday season to bring the most expensive tickets in years.
Southwest Airlines' average third-quarter fare was US$231.69, up almost US$50 on a year earlier, excluding the airline's new fees for checked bags and front-of-cabin seats. Its passenger count fell 3.2% to about 33.5 million, though both figures beat the carrier's forecasts. "Passenger fares came in about $3 above what our forecast was and the more important thing is that passenger volumes also exceeded our expectations," chief executive Bob Jordan said.
Since April, about 9.3 million fewer people have been screened at US checkpoints compared with the same period of 2025, according to the Transportation Security Administration, a drop of under 2%. Jet fuel prices are more than double year-ago levels, with US Gulf Coast spot prices at US$4.63 a gallon.
Not every carrier is shrinking
United Airlines flew 2.4% more passengers in the third quarter and lifted unit revenue by 16%, its biggest increase since the pandemic. "I've been pleasantly surprised at the industry's ability this year to raise yields and pass through much of the increase in fuel prices," chief executive Scott Kirby said. "So it's possible that airlines will continue to focus on yields at the expense of load factor and that alone could get us to double-digit margins next year."
American, United, Delta Air Lines and Southwest all cut their 2026 profit forecasts this month, and American is the only one of the four expecting to post a loss this year. Carriers are also trimming growth plans, which could keep seats scarcer and fares elevated. Demand for premium cabins remains strong.
Budget carriers Frontier Airlines and Allegiant Air, which cater to more price-sensitive travellers, report results in the coming weeks. Bank of America noted that some customers of Spirit Airlines, which went out of business in early May, may simply have stopped flying.
