Airline fares surge 26.7% as travel prices outpace inflation

Airline fares jumped 26.7% in May, even after jet fuel prices had fallen roughly 35% from an early-April peak near $4.88 a gallon. The biggest squeeze landed on international trips: average round-trip fares reached $1,097 on April 20, up 42% from Feb. 23 and 14% from a year earlier, while domestic round trips averaged $361, up 8% from Feb. 23 and 19% year over year.

That split shows how unevenly higher costs are landing on travelers. The U.S. Travel Association said the Travel Price Index rose 9.8% year over year in May 2026, but airline fares climbed far faster, pointing to ticket prices that continued rising even as fuel eased from its spring spike. The association said the elevated prices still reflected energy costs tied to the conflict in the Middle East that began in late February.

The pressure is showing up in airline profits too. On June 7, the International Air Transport Association cut its 2026 profit forecast to $23.0 billion from a prior $41 billion estimate, saying the industry’s net margin would fall to 2.0% and net profit per passenger to $4.50, down from $9.10 in 2025. Total revenue was still expected to reach $1.165 trillion, but the group said war-related disruptions in the Middle East and high fuel prices would erase much of the expected gain. The airline trade group, led by Willie Walsh, also said 2026 oil price increases had outpaced those seen in the 1973 and 1979 supply shocks.

Carriers have already been passing some of that burden through in higher fares, fuel surcharges and schedule cuts. The Bureau of Transportation Statistics said its latest Air Fares database covers the first quarter of 2026, and the Department of Transportation shifted in July 2025 to a 40% sample of domestic carrier tickets, giving analysts a broader read on where prices are moving.

Airline fares have been part of the consumer price index since December 1963, and the U.S. Bureau of Labor Statistics said they carried a relative importance of 0.881 in December 2025. That makes flights a small slice of household budgets, but one that is moving quickly enough to reshape what travelers pay on the routes where airlines still have the most pricing power.
