As the war in Iran strangles the flow of oil around the globe, California’s jet fuel reservoirs are running low.
The state — which refines much of its own fuel in El Segundo and elsewhere but still relies on crude oil imports — has seen its jet fuel stock decline by more than 25% from last year’s peak to a level not seen since 2023, according to data from the California Energy Commission.
The supply is shrinking as a global shortage is already affecting travelers’ summer plans with canceled flights and higher fares. It could even affect plans for people coming to Los Angeles for the 2026 World Cup, which starts in June, said Mike Duignan, a hospitality expert and professor at Paris 1 Panthéon-Sorbonne University.
“People don’t know exactly how this is going to escalate,” he said. “There’s a huge black cloud over the sea for the World Cup and the travel slump that we’re seeing is all linked to this oil shortage.”
As fuel supplies shrink, flight prices are rising. Airlines are adding baggage surcharges to cover fuel costs. Several routes leaving from smaller California hubs, including Sacramento and Burbank, have already been canceled.
Air Canada has suspended flights for this summer, cutting routes from JFK to Toronto and Montreal.
“Jet fuel prices have doubled since the start of the Iran conflict, affecting some lower profitability routes and flights which now are no longer economically feasible,” the airline said in a statement last week.
Europe had just more than a month’s supply of jet fuel left last week, the International Energy Agency said. In an effort to cut costs, the German airline Lufthansa slashed 20,000 flights from its summer schedule this week.
Without a fresh oil supply flowing through the Strait of Hormuz, the situation is unlikely to improve, experts said. The oil reserves countries and companies have in storage are helping fill shortfalls, but the squeezed supply chain could still wreak economic havoc.
“When there’s a shortage somewhere, everything is affected,” said Alan Fyall, an associate dean of the University of Central Florida Rosen College of Hospitality Management. “Airlines are being cautious, and I would say that is a very wise strategy at the moment.”
California’s jet fuel stock reached its lowest levels in two and a half years at 2.6 million barrels last week, down from a peak of more than 3.5 million barrels last year.
The California Energy Commission, which tracks fuel inventory, said the state’s current jet fuel stock is sill sufficient.
“Current production and inventory levels of jet fuel are within historical ranges,” a spokesperson said. “Although supply is tight, no structural deficit has emerged yet. The present tightness reflects short‑term global market stress. As long as refinery operations remain stable, California is positioned to meet regional jet fuel needs.”
Europe has been affected more directly because it relies on the Middle East for the vast majority of its crude oil and many refined products, experts said. California gets crude oil from the Middle East but also from Canada, Argentina and Guyana.
The state has the capacity to refine around 200,000 barrels of jet fuel per day, most of it from refineries in El Segundo and Richmond.
The amount of crude oil originating in the state has been declining since the early 2000s, as state regulations and drilling costs have led to more imports.
California has become particularly vulnerable to supply-chain shocks like the war in Iran, says Chevron, one of the companies that provides jet fuel in the state.
“The conflict in the Mideast Gulf has exposed the danger of California’s decision to offshore energy production,” said Ross Allen, a Chevron spokesperson. “Taxes, red tape and burdensome regulations cost the state nearly 18% of its refinery capacity in just the past year, and we urge policymakers to protect the remaining manufacturing capacity.”
In 2025, 61% of crude oil supply to California’s refineries came from foreign sources, according to the California Energy Commission. Around 23% came from inside the state, down from 35% five years ago.
The state’s refining capacity has also been declining, said Jesus David, senior vice president of Energy at IIR Energy. The West Coast region’s refining capacity has decreased from 2.9 million to 2.3 million barrels a day since 2019, he said.
“California’s had issues prior to the war,” David said. “Nothing new has been built over the past 30 years, and California has closed a lot of capacity.”
The result is higher prices for both gasoline and jet fuel in the state. Jet fuel at LAX costs close to $15 per gallon this week, compared with almost $10 at Denver International Airport and $11 at Newark International Airport.
Gasoline prices have also been hit hard by the global conflict. Average gas prices in California are close to $6 a gallon, around $2 higher than the national average.
The West Coast is a “fuel island” because it’s not connected by pipelines to the rest of the country, United Airlines chief executive Scott Kirby said in an interview last month. That means oil and refined products have to be brought in by ships.
“Fuel price is more susceptible to supply weakness on the West Coast than anywhere else in the country,” Kirby said.
Some airlines might not survive the turmoil if oil prices don’t level out soon, he said. Spirit Airlines, a budget carrier based in Florida, is reportedly facing imminent liquidation if it isn’t bailed out by the Trump administration.
