U.S. Flight Fares Jump 31% as Fuel Costs Rise on Iran War

Summary
KAYAK search data show average fares for U.S.-origin flights are up as much as 31% for domestic trips and 22% for international travel versus the same weeks in 2025.
Fuel costs have been a key driver alongside broader inflation, with prices pushed higher since late February by the U.S.-Israeli war on Iran; fuel can account for up to a quarter of airline operating expenses.
Summer demand is colliding with those higher costs as warmer weather and a recent European heatwave spur travel planning, making budget trips harder to pull off.
Rather than canceling outright, travelers are adjusting by booking later, switching to trains, or taking road trips closer to home despite high gasoline prices.
