“This morning’s technical issue is affecting our ability to automatically process flight plans.
“Until our engineers have resolved this, flight plans are being input manually which means we cannot process them at the same volume, hence we have applied traffic flow restrictions.
“Our technical experts are looking at all possible solutions to rectify this as quickly as possible.
“Our priority is ensuring every flight in the UK remains safe and doing everything we can to minimise the impact.
“Please contact your airline for information on how this may affect your flight. We are sincerely sorry for the disruption this is causing.”

She posted on X, formerly known as Twitter: “On a plane on the runway at Budapest airport. After almost three weeks away from home I am hours from hugging my family.

Sky’s science correspondent Thomas Moore is one of the passengers stuck on a British Airways flight at Heathrow after flying back from San Francisco overnight.
Speaking from the plane, he said the aircraft actually landed ahead of the schedule – but since then they have been stuck on the tarmac.
“The pilots told us that we are in a queue for a gate because all the aircraft giving priority to land can’t get away, so everything is stacking up now,” he said.
“We have an update saying that they’re trying to find space for all the aircraft that are coming in and having to wait, having to queue, because this is going to have a big impact.
“There are planes taking off, but what we are being told is that various aspects of computerised systems used by air traffic control aren’t talking to each to other, so everything is having to be done manually.
“That means things are taking a lot longer than they would be.
“Normally this would be one of the busiest runways in the world, but it is looking very, very quiet.”
Sky News producer Georgia Ziebart, who is stuck on a plane in Palma, Majorca that is set for London Gatwick, said passengers have been told all planes that were in the air at the time the systems went down have been diverted to other countries.
“We’re on the tarmac in Palma, Majorca – we got on the plane an hour ago and shortly after we got on the plane, the pilot made an announcement to say it doesn’t look like we’ll be leaving for a while because there are issues with air traffic control across the whole of the UK.
“We’ve been sat on the plane now for about an hour, still haven’t moved, still haven’t had much information. But staff just said there’s no point in us moving because we can’t actually go anywhere.
“There are people who have been sleeping at the airport since yesterday so it’s completely at capacity inside as well.
“There’s a lot of children on board here, a lot of babies. It’s a three-hour flight. I haven’t got any food. They’ve come around and offered water to everyone but that’s it at the moment.”
