100s of flights cancelled at UK airports due to ATC issue

Hundreds of flights across UK airports were cancelled due to a technical glitch in air traffic control provider Nats' "flight processing system," with major hubs like Heathrow, Manchester, and Gatwick severely affected. While Nats deployed a fix, recovery was proceeding slower than expected, leaving tens of thousands of passengers delayed by up to eight hours and creating a backlog of aircraft across Europe. Airlines including Ryanair and Wizz Air criticized the recurring system failures and called for urgent reforms to the critical infrastructure provider.
