In recent weeks, jet fuel prices have sky-rocketed in California as the ongoing conflict with Iran continues to disrupt global oil supplies and shipping through the Strait of Hormuz. Prices for jet fuel in major U.S. markets are approaching double their early-year levels of about $2.30 a gallon, hitting $4.19 a gallon as of late April 2026, with prices at Los Angeles International Airport hitting near $15 a gallon in recent spikes. California’s jet fuel inventories have plunged more than 25% to a two-year low, exacerbating the crisis as local refiners shut down and the state scrambles for scarce imports from Asia.
The rise is directly related to Middle East tensions, with fighting sharply curtailing oil flows through the vital Strait of Hormuz, a chokepoint that accounts for around one-fifth of global oil shipments. The disruption has sent prices for crude and refined products soaring around the world, hitting aviation particularly hard as jet fuel is one of the largest operating expenses for airlines. Without a quick fix or new supply agreements, experts warn the West Coast could face continuing shortages and even higher costs through the peak summer travel season.
Airlines are already taking aggressive action to protect margins and keep operations going. Norse Atlantic Airways has cancelled all its summer flights out of Los Angeles International Airport due to unsustainable fuel prices, the airline announced in California. Delta Air Lines has cut some domestic routes, including some flights from Detroit to New York. Air Canada has reduced service to some U.S. destinations. United Airlines CEO Scott Kirby said the carrier is raising fares by as much as 20% on the routes affected and proactively canceling off-peak-time flights to save fuel.
The ripple effects extend well beyond California. Lufthansa Group has announced plans to cut about 20,000 short-haul flights in its European network through October 2026, which is expected to save some 40,000 metric tons of jet fuel. The cuts are mainly concentrated on less profitable regional routes to major hubs in Frankfurt and Munich and will affect Lufthansa Airlines, Austrian Airlines, Brussels Airlines, SWISS and ITA Airways. Other airlines, including British Airways, Air France-KLM and some Asian carriers have also cut back their schedules, with aviation analytics firm Cirium saying almost all of the world’s 20 largest airlines have canceled or pared back flights in May.
Passengers are feeling the impact in the form of higher ticket prices and new fees. Major U.S. carriers including Delta, Southwest and JetBlue have increased the price for checked baggage and many have added fuel surcharges. Average domestic air fares have surged 10-15% for summer travel, with international routes to Europe soaring as much as 20%. Analysts expect more turbulence, including possible route consolidations and lower frequency on popular vacation routes.
The developments pose special problems for California travelers contemplating summer trips or international travel. Gasoline prices are 45% above the national average in the state and the added pressure from aviation could hurt tourism and business travel. Experts say prolonged instability could complicate large-scale events, including potential travel for the 2026 FIFA World Cup.
Some carriers have locked in short term fuel supplies and are looking at alternate procurement strategies, but there is a broader outlook of uncertainty. Any delay could bring Europe closer to real shortages by mid-May and keep pressure on U.S. prices moving higher, even as peace talks continue in the background. Travel experts recommend booking early, being flexible with dates and routes, and monitoring airline communications for schedule changes.
The fuel crisis is a reminder of the aviation sector’s exposure to geopolitical shocks and global energy markets. With summer approaching, the triple threat of rising costs, shrinking capacity and supply constraints are poised to turn what should be a bustling travel season into one of higher prices, fewer options and possible disruptions for millions of passengers globally.
