Jet fuel prices in Europe have roughly doubled and reserves may only last about six weeks, warning of imminent flight disruptions, IEA head said.

The shortage matters because airlines could raise ticket prices, reduce routes, and cancel flights, hitting travelers and the continent’s tourism‑dependent economies – a ripple effect that may reach businesses beyond aviation.

The International Energy Agency confirmed that jet fuel costs have climbed to about twice their pre‑war level, a surge linked to the ongoing conflict in Iran that has strained global oil supplies[1].

"Jet fuel prices have roughly doubled since the war in Iran began," the Euronews report said the agency’s analysis[1].

The agency’s head said that Europe has "maybe six weeks or so of jet fuel left," indicating that existing stockpiles could be exhausted within a month and a half[2].

The war in Iran has squeezed global oil output, reducing the feedstock for jet fuel and driving up prices while depleting European reserves[1].

Airlines are already bracing for the impact. "Possible flight cancellations soon if oil supplies remain throttled," the IEA chief said in a statement to MSN Canada[2]. Carriers may resort to curbing less profitable routes, and passing higher fuel costs onto passengers.

**What this means** The jet‑fuel crunch underscores how geopolitical conflicts can quickly translate into consumer‑level disruptions. With only weeks of fuel on hand, European airlines face a tight window to secure alternative supplies or cut capacity, meaning travelers should expect higher fares and possible itinerary changes in the coming weeks.

The rapid price rise and dwindling reserves illustrate the vulnerability of Europe's aviation sector to external supply shocks, likely prompting airlines to adjust schedules, raise fares and seek new fuel sources, while travelers should prepare for potential disruptions.
