Flights delayed after air traffic control hit by technical fault Flights from Scottish airports are facing delays after the UK's air traffic control system was hit by a technical fault. The problem, which emerged on Saturday morning, is affecting the NATS control centre in Swanwick, Hampshire. A spokesman for NATS, which operates the country's air traffic control services, said: "Due to a technical problem at Swanwick we are currently experiencing some difficulty switching from night time to daytime operation. This may result in some delays for which we apologise. Engineers are working to rectify the problem as soon as possible. So far, two Scottish airports have warned passengers to expect delays. Glasgow Airport tweeted: "A technical issue with air traffic control is resulting in some flight delays. Pls check with your airline for specific flight info. A spokesman for the airport told STV News that flights could be delayed for up to three hours. Edinburgh Airport tweeted: "Due to a technical fault with @NATSPressOffice there are delays on southbound flights. Contact your airline if intending to fly. A spokesman said flight delays as of 9am ranged from one and a half hours to three and a half hours. A spokesman for Aberdeen Airport said easyjet and British Airways flights out of the airport were experiencing delays. On its website, Ryanair apologised for any inconvenience, writing: "Ryanair has been advised of an equipment failure within UK air traffic control which will cause significant flight delays and possible cancellations." EasyJet advised passengers to check in for flights as normal "as the situation can improve," but suggested they refer to the airline's flight tracker page for updates. A message on its website read: "Although this is beyond easyJet's control, we apologise for any inconvenience that you may experience today."
