Jet Fuel Crisis Drives Airline Price Hikes and Flight Cancellations

Airlines worldwide are slashing flight schedules and raising ticket prices as a global jet fuel shortage driven by the U.S.-Israeli war with Iran disrupts air travel, leaving passengers facing fewer options and higher costs.

The conflict, which began on Feb. 28, 2026, after the U.S. And Israel launched military strikes against Iran, has severely disrupted oil shipments from the Middle East, a critical source of jet fuel for global aviation. Approximately 75% of Europe’s jet fuel supply originates from the region, with much of it transported through the Strait of Hormuz—a key chokepoint now effectively closed due to the conflict, according to industry data cited in primary reporting.

Jet Fuel Prices Surge, Forcing Airlines to Cut Flights

The cost of jet fuel has skyrocketed since the war’s onset. In the U.S., prices have risen by nearly 70%, according to the Argus U.S. Jet Fuel Index. European benchmark prices reached an all-time high of $1,838 per tonne in early April 2026, more than doubling pre-war levels of $831 per tonne, as reported by aviation industry analysts.

The financial strain has forced airlines to take drastic measures. Major carriers, including United Airlines, Lufthansa, KLM, Delta Air Lines, and Air India, have announced significant flight cancellations. KLM, for example, will scrap 80 return flights from Amsterdam’s Schiphol Airport over the coming month, while Lufthansa has canceled 20,000 flights. United Airlines has revised its full-year earnings outlook downward, citing the fuel crisis as a primary factor.

Global flight capacity for May has already been reduced by about 3%, with nearly all of the world’s 20 largest airlines cutting schedules, according to data from aviation analytics firm Cirium. The firm had initially projected 4% to 6% growth for 2026 but now warns that a decline of up to 3% is possible under current conditions.

“It appears extremely likely that more reductions are ahead,”

Richard Evans, senior consultant at Cirium, wrote in a recent report.

Passengers Face Higher Costs and Fewer Options

The crisis has led to a sharp increase in airfare. The average cost of an international flight departing from the U.S. Has risen by approximately 37% since the war began, climbing from $776 on Feb. 23 to $1,064 by mid-April, according to travel search engine Kayak. Domestic U.S. Airfare has also increased, from $335 to $358 over the same period.

Airlines are passing fuel costs onto passengers through higher ticket prices and additional fees. United Airlines CEO Scott Kirby indicated that fares may need to rise by as much as 15% to 20% to offset the surge in fuel expenses. Delta Air Lines CEO Ed Bastian similarly warned of an industry-wide test, noting that the airline expects an additional $2.5 billion in fuel costs this quarter alone.

“Any flying that we’re doing that’s on the margin, maybe not producing the yields we’d like, is likely going to be reconsidered,” Bastian said in a recent statement.

European Measures Aim to Mitigate Shortages

The European Commission has proposed emergency measures to address the fuel shortage, including a plan to optimize jet fuel distribution across EU member states. The proposal, part of a package called AccelerateEU, aims to prevent localized shortages by ensuring more equitable access to available supplies. However, industry experts warn that the situation remains precarious, with the European Union’s Energy Commissioner describing the coming summer as “challenging” even under the best-case scenario.

For now, airlines continue to operate normally in some regions, such as the UK, where Airlines UK—representing major carriers—has stated that no immediate supply issues have been reported. However, the broader outlook remains uncertain, with analysts predicting further disruptions if the conflict persists.

What Travelers Can Do If Their Flight Is Canceled

Passengers affected by cancellations have several options. Airlines are generally required to offer refunds or rebooking without additional charges if a flight is canceled. In the U.S., for example, the Department of Transportation mandates that airlines refund the full cost of a ticket if a passenger chooses not to rebook.

Travel experts recommend the following steps to minimize disruptions:

• Monitor flight status closely through airline notifications and check for updates before heading to the airport.
• Book directly with airlines rather than third-party sites to simplify rebooking or refund processes.
• Be aware of regional differences in passenger rights—rules vary by country regarding compensation and rebooking options.

While some airlines are providing advance notice of cancellations, the situation remains fluid. Travelers are advised to prepare for potential changes and consider flexible booking options where possible.

The jet fuel crisis shows no immediate signs of resolution, with the U.S. Naval blockade of the Strait of Hormuz continuing to restrict Iranian oil shipments. As airlines grapple with soaring costs and limited supply, passengers should brace for ongoing disruptions throughout the summer travel season.
