Recovery from disruptions to flights leaving the UK caused by an air traffic control issue will “take some time”, Nats has said, after more than 400 flights were cancelled.
Birmingham Airport said the issue was affecting airspace in the south of the UK and was “impacting a significant number of departing flights across the country”.
Heathrow Airport, the UK’s largest airport in west London, confirmed it was among those impacted but said arriving flights were “currently not affected” in a statement on Tuesday afternoon.
