U.K. air traffic control glitch cancels nearly 300 flights

A U.K. air traffic control glitch caused nearly 300 flight cancellations on Tuesday, September 8, 2026, disrupting travel across major airlines and airports. Britain's National Air Traffic Services said engineers implemented a fix and the system was recovering, but the issue affected departing flights at London Heathrow, Stansted, City, and airports in Manchester, Birmingham, and Scotland. Airlines including British Airways, EasyJet, KLM, and Lufthansa saw dozens of cancellations. EasyJet reported delays across Europe, while arriving flights appeared unaffected. The cause of the technical problem remained unclear, and passengers were advised to check flight status with their airlines.
