US Airlines Hit by Fuel-Driven Financial Struggles

• United Airlines is modeling Brent oil at $175/barrel through 2027, which would increase its annual fuel bill by $11 billion—more than twice its best-ever annual profit
• Moody's estimates that if Brent had averaged $80/barrel instead of $69 last year, operating profit across rated U.S. airlines would have fallen by roughly half to about $6 billion
• Spirit Airlines warned the fuel spike poses 'immediate and substantial negative impact' that could derail creditor talks and force liquidation, while JetBlue is expected to burn cash in 2025 with only $2.5 billion in liquidity and no fuel hedges

US Airlines Face Fuel-Driven Financial Pressure

Surging fuel prices are creating a significant stress test for U.S. airlines, threatening to widen the competitive gap between strong and weak carriers. Jet fuel prices jumped to $4.24 per gallon from $2.50 before U.S.-Israeli strikes on Iran, with Brent crude trading around $112 per barrel as of March 30.

Key Impact and Figures

United Airlines CEO Scott Kirby is modeling Brent oil at $175 per barrel, remaining above $100 through 2027. Under this scenario, United's annual fuel bill would increase by approximately $11 billion—more than double its best-ever annual profit. American Airlines reported the fuel surge added $400 million to first-quarter costs, with each 1-cent fuel price increase costing $50 million annually.

Moody's estimates that if Brent had averaged $80 per barrel (versus $69) last year, operating profits across rated U.S. airlines would have dropped by half to $6 billion.

Winners and Losers

Strong Position: Delta Air Lines and United Airlines are best positioned due to high operating margins, strong liquidity, and low leverage. Both can absorb prolonged shocks without abandoning strategic plans.

Vulnerable Carriers: Low-cost and ultra-low-cost carriers face the greatest risk. JetBlue, Spirit, and Frontier were already unprofitable before the spike. Spirit Airlines, currently in bankruptcy, warned that sustained high fuel prices could force liquidation. JetBlue has $2.5 billion in liquidity but no fuel hedges and expects to burn cash through 2027. Frontier posted a net loss with just $874 million in liquidity.

Market Implications

Analysts predict a potential industry shakeout similar to 2008, with weaker carriers likely to cut capacity, defer spending, or seek additional borrowing. J.P. Morgan suggests this could ultimately benefit larger airlines post-2027 through reduced competition.
