Disruption to jet fuel supply is expected from “early May” if the US-Israel war on Iran continues beyond April, Ryanair chief executive Michael O’Leary said on Wednesday, giving rise to fears the air fares could be about to skyrocket ahead of the summer. Jet fuel prices have roughly doubled in major markets since the onset of the war, driven by an effective blockade of the Strait of Hormuz, through which about 20 per cent of the world’s traded jet fuel supply normally passes.

International Energy Agency head Fatih Birol said on Wednesday the lack of jet fuel and diesel will hit Europe “in April or May”. Trump has in all likelihood correctly predicted the price of oil will shoot down when the Iran crisis comes to an end, and the same is likely true of jet fuel.
