What happened

American Airlines (AAL) stock fell 5% on Monday as Brent crude topped $104 a barrel, hammering carriers with zero fuel hedges and prompting United's CEO to warn fares will rise up to 20%. Oil has surged 55% over the past year after a February Strait of Hormuz disruption cut crude flows from 9 million barrels a day to under 2 million. Jet fuel has jumped 100% since January — twice crude's pace — as refineries pay up for scarce supply. American Airlines and United carry zero fuel hedges, so each one-cent rise in jet fuel costs AAL about $46 million a year.

Why it matters

Airline stocks are a direct window into what surging oil does to everyday consumer costs: when jet fuel doubles, airlines either absorb the hit or pass it on as higher ticket prices. That is already happening — August airfares were 23% higher than a year ago, and Thanksgiving fares are running 31% higher. Unlike past oil shocks, U.S. carriers hold no financial hedges to cushion the blow, so as long as crude stays above $100 a barrel, high fares are likely to stick.
