What happens to flights if the world runs out of oil? Well, obviously they will be grounded. To be more specific, is it possible, if the war in Iran does not resolve and the strait of Hormuz remains blocked, that airlines will simply run out of aviation fuel?
It’s not a question anyone has had to ask before. Air travel has hit some hurdles this century that nobody could have seen coming – Covid, of course, but also the Icelandic volcano in 2010, which closed much of European airspace for eight days, cost an estimated €3.75bn (£3.2bn) and caused untold supply chain chaos. There have been problems contained within a country or region – the Heathrow substation outage and the Iberian energy crisis, both last year, both closing airports – but since air travel began, it has never been globally impeded by a fuel shortage.
