A sharp rise in jet fuel prices is pushing three of the largest U.S. airlines — American Airlines, United Airlines and Southwest Airlines — to scale back planned flight schedules as carriers work to protect profitability.
American Airlines says higher fuel prices are adding roughly $1 billion to its fourth-quarter costs alone. The airline plans to continue adjusting capacity, particularly where higher operating costs make routes less attractive.
United Airlines is also removing some flights planned for December, with executives warning that additional schedule changes could extend into the first quarter of 2027 if fuel prices remain elevated.
Southwest Airlines has already reduced its planned 2026 capacity growth by roughly half. The carrier says further cuts could follow if fuel costs stay high for longer.
Despite the capacity reductions, executives at all three airlines say travel demand remains strong. United reported robust fourth-quarter bookings, while premium, corporate and economy travel continue to show resilience. American also expects significant revenue growth, helping offset much of the increased fuel expense.
The strategy is becoming clearer across the industry: airlines are looking to preserve fares and revenue where demand remains strong while removing flights on routes that no longer make economic sense.
The latest fuel surge highlights how quickly energy costs can reshape airline schedules, fares and profitability — even when passengers continue to fly in large numbers.
