- Around 1,300 flights were cancelled on Tuesday due to a technical issue with the National Air Traffic Control Service (Nats), with further cancellations on Wednesday morning.
- Tens of thousands of passengers experienced severe delays and travel chaos at major UK airports, including Heathrow and Gatwick; a further 279 cancellations were recorded early on Wednesday at Heathrow and Gatwick.
- Nats confirmed the technical fault was resolved approximately four hours after it started, but warned it will take time for schedules to return to normal.
- Passengers travelling on Wednesday have been advised to check the status of their flight with their airline before arriving at the airport.
- The Transport Secretary has summoned Nats chief executive Martin Rolfe to explain the cause of the system failure and the organisation's response.
