Major airlines cut flights as higher jet fuel prices hit carriers

• American Airlines' Q4 jet fuel costs are running $1 per gallon higher than projected in July, adding roughly $1 billion to its fuel bill
• United Airlines is canceling some December flights and may make further capacity adjustments into Q1 2027 if fuel prices remain elevated
• Southwest Airlines has already cut about half of its planned year-over-year capacity growth for 2026, though executives report fall bookings remain stronger than expected across all carriers

Summary

Major U.S. airlines are cutting flight capacity in response to surging jet fuel prices, according to executives speaking at Morgan Stanley's 14th Annual Laguna Conference. The global average jet fuel price increased 6.1% week-over-week to $181.46 per barrel last week, according to IATA.

Key Financial Impacts:

American Airlines: Fourth-quarter jet fuel prices are running approximately $1 per gallon above July projections, adding roughly $1 billion to fuel costs. Despite this, the carrier expects third-quarter revenue to rise 16-19% year-over-year, with CFO Devon May indicating capacity adjustments will continue through Q4.

United Airlines: CFO Michael Leskinen confirmed some December flights will be canceled due to elevated fuel costs, with potential further adjustments into Q1 and 2027 if prices remain high. However, Q4 bookings remain "tremendously strong" across premium, corporate, and economy segments, with minimal evidence of demand destruction.

Southwest Airlines: CFO Tom Doxey revealed the carrier has already reduced about half of its planned 2026 year-over-year capacity growth, though a company spokesperson clarified adjustments have been minimal to date. Stronger-than-expected fall bookings are helping offset higher fuel costs, allowing Southwest to maintain Q3 earnings guidance.

Market Implications:

The airline sector faces margin pressure from fuel cost inflation, though demand remains resilient across all cabin classes and traveler types. Carriers are prioritizing capacity discipline over market share, potentially leading to reduced seat availability and higher ticket prices in late 2025 and 2026. The industry's ability to pass fuel costs to consumers will be critical for maintaining profitability.
