Which airlines are cutting flights amid Hormuz fuel disruption?

Scores of international airlines have issued warnings and canceled thousands of flights over fears of jet fuel shortages sparked by the Iran war and the near-total closure of the Strait of Hormuz.

Concern over tightening fuel supplies has driven prices sharply higher, forcing airlines to reassess the profitability of routes and scale back operations.

The Strait of Hormuz is critical to the global aviation industry, with an estimated 25% to 30% of the world’s jet fuel passing through the waterway before the war. European carriers are particularly exposed, relying on the strait for roughly half of their jet fuel imports, leaving them among the hardest hit by the disruption.

The International Energy Agency warned last week that Europe could run out of jet fuel within “six weeks,” as stockpiles approach critical levels.
