US Airfares May Stay High Despite Declining Jet Fuel Prices

U.S. travelers may continue to face high airfares even if jet fuel prices fall, as volatile costs and airline scheduling decisions slow any pass-through of savings. Fuel prices surged after the Iran war began, then dropped sharply in the spring before rising again; meanwhile, average domestic fares climbed from $405 in late 2025 to $436 in April-June 2026, excluding optional fees. Airlines set schedules months ahead and sell seats earlier, limiting their ability to adjust quickly when costs change, and they cannot raise prices on tickets already sold to recoup sudden fuel increases. Carriers have also raised fares and fees and cut less-profitable flights, reducing available seats and potentially keeping prices elevated. Industry analysts say uncertainty itself makes airlines cautious about lowering fares, while some carriers have signaled schedule or growth reductions.
Jet fuel rose faster than oil during the war, partly because supplies of refined fuel were tight, adding pressure beyond the increase in crude prices.
Major U.S. airlines said that higher passenger revenue initially covered only part of their sharply increased fuel costs.
United removed some December flights, while American indicated its growth could slow in 2027, illustrating how fuel costs have affected specific airline plans.
Brett House said, “It’s not just the level of fuel costs that is a problem or a challenge for airlines. It’s also the volatility.”
