A NATIONWIDE air traffic control issue has affected all outbound flights from the UK this afternoon.
Flightradar, which monitors air traffic at all time, said the issue affected southern parts of the UK, adding that the greatest impact would have been felt at Heathrow Airport, which is the biggest airport in the country.
Travellers were advised to check with their airline on the status of flights.
After about 30 minutes since the initial alert, air traffic control provider Nats engineers had fixed the problem and it was "in the process of restoring normal operations."
A statement from Nats, previously said: “As a result of a technical issue at Nats Swanwick air traffic control centre, we are limiting the number of aircraft flying in the London control area in order to ensure safety, which is always our first priority.
“We apologise for any delays this may cause."
They added: “Our engineers are working hard to resolve the problem as quickly as possible and we are working closely with airlines to help minimise disruption.
“At this stage we cannot say how long it will be before operations are back to normal.
“Please check with your airline on the status of your flight.”
What are airports across the UK saying?
Edinburgh Airport held all flights while awaiting further information.
Birmingham airport said “departing flights from many UK airports" had been suspended.
Newcastle Airport also confirmed all departures were suspended.
In a statement, Gatwick Airport also said the technical issue meant there were no departures while the situation was being resolved.
“A technical issue impacting Nats is affecting all outbound flights across the UK,” the airport said on X.
“There are currently no departures from London Gatwick while the situation is being resolved.
“We are working with Nats to resume flights as quickly as possible. Inbound flights are still landing at the airport.
“Passengers should check the status of their flights with their airline.”
