Severe thunderstorms that struck London on June 30, 2026, resulted in the cancellation of over 900 flights at two of the city’s principal airports, Heathrow and Gatwick. These cancellations have left roughly 40,000 passengers stranded, leading to widespread disruption across the region’s air travel network.
The adverse weather conditions triggered considerable delays and disrupted schedules throughout the day, heavily affecting travelers’ plans. Passengers at both airports experienced difficulties as flights were halted or indefinitely delayed amid the storm activity. The intense thunderstorm occurrences underscored the vulnerability of flight operations to extreme weather at these major UK hubs.
