Jet-fuel crunch threatens summer travel as Hormuz disruption bites supply

A looming jet fuel shortage in Europe and Asia tied to the Iran war and the closure of the Strait of Hormuz could raise airfares and trigger flight cancellations if supplies don’t resume soon. The IEA says Europe may have about six weeks of jet fuel left, and prices have roughly doubled, potentially forcing longer routings, less scheduling flexibility, and fewer low‑fare options, with carriers like KLM, EasyJet, Lufthansa, and Delta already adjusting operations and fees.
