On June 30, 2026, London’s Heathrow and Gatwick airports experienced significant operational disruption as more than 900 flights were cancelled. This disruption resulted in roughly 40,000 passengers being stranded across the two major airports, causing substantial travel interruptions.
These widespread cancellations were directly linked to severe thunderstorms impacting the London area on the same day. The adverse weather conditions affected both airports’ ability to maintain normal flight schedules, leading to extended delays and cancellations.
