Severe thunderstorms on June 30, 2026, led to the cancellation of over 900 flights at London’s Heathrow and Gatwick airports. The adverse weather conditions forced airlines to pause operations, resulting in widespread flight disruptions across these major UK airports.
As a consequence of the cancellations, approximately 40,000 passengers were left stranded at airports across the UK, with thousands affected at both Heathrow and Gatwick. Travelers faced extended waiting times and significant delays amid the storm-related grounding of flights.
