More flight delays expected after hundreds cancelled by air traffic control glitch
Departures from a number of airports are affected by a technical problem affecting air traffic control provider Nats.
Flight delays are expected to continue on Wednesday after an air traffic control problem cancelled hundreds of flights across the UK.
Tens of thousands of passengers were affected by the disruption and tracking website FlightRadar24 said up to 1,000 flights were cancelled after a glitch affecting air traffic control provider Nats.
Its boss Martin Rolfe apologised, telling the BBC there would be a full investigation into what had gone wrong, after Nats said resolving the issue had taken "longer than hoped".
Airports across the UK said they were experiencing cancellations and delays and advised people to check their flight details before travelling.
