Strait of Hormuz closure triggers global jet fuel crisis, airlines ground planes

The closure of the Strait of Hormuz has created the largest oil supply shock on record, disrupting aviation globally as of April 2026. Airlines across Asia, Europe, and beyond are cancelling routes, raising fares, and grounding aircraft due to jet fuel shortages. Carriers including Ryanair, Lufthansa, and SAS are implementing emergency measures. This supply crisis directly affects American travelers, fuel prices, and global commerce, with May expected to see peak disruptions as European airlines face acute fuel scarcity.
