UK flights disrupted by major air traffic control glitch, affecting thousands of travelers.

Airlines are struggling to recover from a major air traffic control glitch that disrupted flights across the UK on Wednesday, affecting thousands of passengers. Nats, the ATC provider, reported that its systems are now operational, but many flights were delayed or cancelled, causing ongoing issues for travelers. Ryanair called for Nats' CEO to resign, citing past failures. Passengers may be entitled to food or hotel stays but not compensation, as the issue is considered beyond airlines' control.
