UK travellers faced more misery on Wednesday with more than 150 flights scrapped across the country, as Britain's air traffic control service scrambled to recover from a technical glitch that sparked chaos. Aircraft tracking website FlightRadar24 said 177 flights scheduled for Wednesday had already been axed, following 1,300 cancellations to and from UK airports a day before. Nearly all the latest affected flights were at Britain's busiest airport Heathrow in London, FlightRadar24 wrote on X. The National Air Traffic Services (NATS) said it was still working to resolve disruption following a "system issue". "This has been a very complex recovery and has created difficulties for the whole aviation network, from which it will take time to recover," said NATS in an X post late Tuesday.

Rolfe told UK outlet Sky News he accepted "full responsibility" but declined to say if he was considering quitting his job. Transport Secretary Alexander said earlier on X she was "seeking assurances that lessons will be learned and systems that support aviation are up to the job". But Ryanair COO Neal McMahon repeated his calls for Rolfe to be fired, accusing him of having again "failed UK travellers". "Enough is enough, it's time for the UK government to intervene ... and put somebody in charge who can do the job." 'Knock-on impact'
