A major air traffic control disruption swept across the UK, triggering widespread flight cancellations and leaving passengers stranded at airports nationwide.
The UK’s National Air Traffic Services confirmed that a technical issue with its air traffic control system began on Tuesday, September 8. While the issue was resolved that same night, delays continued rippling through the system into Wednesday, September 9, according to the Associated Press, reported Thursday, September 10, 2026.
The Scale of the Disruption
The delays spread across 15 airports in the UK and surrounding regions, according to flight tracking service Flightradar24. Heathrow Airport was hit hardest.
“So far, 177 flights have been canceled on Wednesday, with the vast majority occurring at Heathrow Airport,” the tracking service reported.
Passengers Describe a Chaotic Experience
One passenger, Josie Donoghue, spent three hours stuck aboard a plane at Gatwick Airport before her Ryanair flight to Ireland was ultimately canceled.
“Getting out of that airport felt like trying to escape Alcatraz,” she said, referencing the notoriously inescapable former island prison in San Francisco Bay. “The situation there was an absolute nightmare. That’s really the only word I can use to describe it.”
Departures at Heathrow eventually resumed, but the busy airport halted incoming flights for the rest of that evening due to the disruption, warning of further delays to come.
Passengers on a British Airways flight bound for Baltimore disembarked after being held on the runway for four hours. During the extended delay, cabin crew served pasta and chicken curry while patient passengers watched movies or walked the aisles to pass the time.
The Trouble Didn’t End on the Plane
Unfortunately, passengers soon discovered their ordeal wasn’t over. Chaos followed at baggage claim, where travelers were reportedly told no one could assist them and were instructed to file claims for their luggage separately.
British Airways was ultimately forced to cancel or divert more than 100 flights. Ryanair reported that more than 65,000 of its passengers were affected by the disruption, with more than 50 flight schedules canceled outright.
“The severity of this issue means there will be significant knock-on effects,” a British Airways spokesperson said.
Several passengers took to social media to voice frustration over being stuck aboard aircraft for hours, along with what they described as poor communication from airline staff throughout the ordeal.
“This incident was completely outside of our control and has been deeply frustrating for both our customers and our staff, as aircraft and crew positioning fell out of sync with the planned schedule,” the spokesperson added.
Budget carrier EasyJet stated that several of its flights were unable to operate, and that the system disruption caused “flight delays across Europe.”
Which Airports Were Affected
Airports impacted by the disruption include Stansted, London City, Manchester, Birmingham, Gatwick, and several airports across Scotland. Airport authorities are urging passengers to check their flight status directly with their respective airlines.
What This Means If You’re Flying Through the UK Soon
If you have a flight booked through any UK airport in the near future, it’s wise to check your flight status well before heading to the airport, as knock-on delays from disruptions like this can linger for days after the initial issue is resolved. Given how quickly baggage claim and rebooking situations can turn chaotic during large-scale disruptions, building in extra time and having a backup plan for connecting flights is strongly advised.
