Nearly 300 flights were cancelled on September 8, 2026, across multiple UK airports including Heathrow, Stansted, City, Manchester, Birmingham, and various airports in Scotland. Airlines affected by the disruptions included British Airways, EasyJet, KLM, and Lufthansa. The cancellations predominantly impacted departing flights.
Technical Fault in UK’s Air Traffic Control System
The widespread flight disruptions were caused by a technical fault in the UK’s air traffic control system managed by National Air Traffic Services (NATS). Engineers at NATS worked urgently to address the problem throughout the day. The specific cause of the system failure was not immediately identified.
Impact on Passengers and Flight Operations
The technical issue resulted in many cancellations and delays, especially affecting
short-haul departures from Heathrow to European destinations. EasyJet reported some of its flights were unable to operate, with delays extending across Europe. Passengers were advised to check flight statuses directly with their airlines. Arriving flights at UK airports reportedly did not experience delays.
Heathrow Airport’s official website indicated cancellations and delays mostly concentrated on European routes, while other airports like Stansted and City also confirmed operational disruptions. The fault caused delays beyond the UK, extending disruptions to flights throughout Europe.
Recovery Efforts and Official Statements
National Air Traffic Services issued an update in the afternoon, stating they had implemented a fix and that the flight
system was beginning to recover. NATS apologized for the operational disruptions caused by the technical issue. Airlines including British Airways, EasyJet, KLM, and Lufthansa had to adjust their schedules in response to the evolving situation.
