IEA Warns Six-Week Jet Fuel Cushion as Airlines Start Cutting Routes
The International Energy Agency warned Europe may have only six weeks of jet fuel as airlines begin cutting routes amid Iran war supply disruptions. IEA Director Fatih Birol told the AP Europe has "maybe six weeks" of jet fuel if disruptions continue. Argus Media says about 40% of Europe's jet fuel imports transit the Strait of Hormuz and none has passed since the war began.
Jet fuel now makes up roughly 25-30% of airline operating costs, and prices have roughly doubled since the Iran war started, squeezing profits and prompting fare and fee increases. Carriers including Delta, Air Canada, KLM and Lufthansa have announced route cuts, suspensions and groundings for this summer and beyond. The IEA report found some countries have under 20 days of jet fuel cover and warned that falling below 23 days could trigger airport shortages and cancellations.
Coverage has shifted as short-term signs of easing emerged during a 10-day Israel-Lebanon ceasefire when Iran declared the Strait of Hormuz "completely open" and U.S. leaders echoed that message. The Wall Street Journal linked that declaration to a sharp one-day drop in oil benchmarks and a market rally, but the IEA and other analysts caution reopening must be durable to prevent renewed shocks. Industry groups and social posts warned that even with the strait open, backlogs, damaged infrastructure and tanker transit times will keep supplies tight for weeks or months, and the International Air Transport Association said normalization could take months.

đź“Ś Key Facts
- IEA Director Fatih Birol warned Europe has "maybe six weeks" of jet fuel left and described the situation as potentially the global economy's "largest energy crisis"; the IEA reported some European countries have under 20 days of jet‑fuel coverage and that falling below about 23 days could trigger physical shortages and flight cancellations.
- Argus Media estimates the Strait of Hormuz supplies roughly 40% of Europe’s jet‑fuel imports, and no jet fuel has transited the strait since the war began.
- Iran declared the Strait of Hormuz "completely open" during a 10‑day Israel‑Lebanon ceasefire through at least April 26, but that reopening is explicitly time‑limited; U.S. and Iranian signals were mixed (Trump said the strait "is fully open" while the U.S. reportedly kept a blockade on Iranian ports).
- Markets reacted to the easing signals: Brent crude fell about 9.1% to $90.38/barrel and the main U.S. crude benchmark fell about 11% to $83.85, while the S&P 500 and Nasdaq closed at record highs on perceived easing of tensions.
- Jet fuel prices have roughly doubled since the Iran war began on Feb. 28; fuel makes up roughly 25–30% of airline operating costs (about 30% cited in some reports).
- Airlines are cutting routes and raising fares/fees in response: Delta announced several seasonal route cancellations; Air Canada suspended Toronto and Montreal service to JFK June 1–Oct 25 citing doubled jet‑fuel costs; KLM and Lufthansa have adjusted schedules, shut a regional carrier and grounded planes.
- Industry analysts warn U.S. and other travelers may face diversions, added stops or other disruptions on transatlantic and overseas flights if European jet‑fuel shortages persist, with the IEA "six weeks" warning framed as a particular risk for summer travel.
- The fuel shock is rippling through the broader economy: U.S. retail gasoline prices are about 21% higher than a month earlier (BLS), the U.S. Postal Service plans an 8% shipping‑price increase and UPS has imposed a fuel surcharge, food banks report rising demand, and a U.N. report says countries such as Thailand, the Philippines and India are curbing or reallocating fuel—affecting production and exports.

- Air Canada is suspending Toronto and Montreal routes to New York JFK from June 1 through October 25 explicitly because jet fuel prices have doubled since the start of the Iran conflict.
- KLM Royal Dutch Airlines is adjusting its schedule and dropping routes it calls no longer financially viable, and Lufthansa is shutting down a regional airline and grounding planes over higher kerosene prices.
- Industry analyst Henry Harteveldt told CBS he has never seen disruptions "on such a large scale" and warned U.S. travelers could face diversions or added stops on Europe flights due to fuel shortages.
