The global aviation industry is facing growing uncertainty over imminent flight disruptions, as a prolonged blockade of the Strait of Hormuz continues to erode jet fuel supplies across key markets in Asia and Europe. Since the closure of the critical chokepoint on February 28 following the start of US and Israeli airstrikes on Iran, nearly 20% of the world’s daily crude oil and liquefied natural gas shipments – the core input for jet fuel production – have been cut off from global markets, raising urgent alarms about looming shortages.
