Passengers sit with their luggage outside Terminal 3 of London Heathrow airport, west of London following major disruption due an issue affecting the NATS air traffic control systems. Flights to and from the UK were cancelled on September 8, due to a "technical issue" affecting UK's National Air Traffic Services, which says it is working to resolve the situation.
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".
