LONDON, Sept. 9 (Xinhua) -- Up to 1,300 flights were canceled to and from airports in Britain on Tuesday, and 177 flights have been canceled so far on Wednesday, nearly all at London's Heathrow Airport, according to air traffic tracker Flightradar24.
National Air Traffic Services (NATS) said on Tuesday afternoon that it identified a technical issue with its flight processing system, disrupting departures across the country and causing delays and cancellations.
NATS said they had implemented a fix but recovery had taken longer than expected.
"Our system issue is now resolved," it said. "We are operating normally and working as hard as possible to clear the backlog of flights."
