Jet Fuel Has Doubled. Here’s Why I’m Still Bullish on Airlines

Since the U.S. and Israel launched strikes on Iran on February 28, jet fuel prices in the U.S. have more than doubled. According to data from the Energy Information Administration (EIA), the year-to-date percent change in U.S. jet fuel prices stood above 120% as of the end of March.

Oil markets reacted swiftly to President Donald Trump’s address to the nation this week, with U.S. crude surging 12% to over $113 per barrel and Brent jumping 8% above $109. The national average for a gallon of gasoline crossed $4.00, the highest since Russia’s invasion of Ukraine in 2022.

There’s no sugarcoating it: for the aviation industry, which was on track for a record $41 billion in global profits in 2026, this is a serious headwind.

But it’s important that I point out that this isn’t the first shock airlines have had to face. As I see it, the industry’s long-term investment case remains firmly intact.

The Fuel Problem

Jet fuel typically accounts for somewhere between 20% and 40% of an airline’s total operating costs, depending on the carrier, its routes and the efficiency of its fleets. Unlike labor costs or lease payments, fuel prices are set by global commodity markets. They’re beyond any single airline’s control, and they can change very fast, as we saw in March.

What makes the current situation particularly impactful, of course, is the closure of the Strait of Hormuz, which handles an enormous share of the world’s seaborne oil trade. Looking just at China, the world’s number one oil importer, about 38% of its supply originates in the Persian Gulf, according to CLSA research.
