Thousands of travelers, including celebrities like Rebel Wilson, Benedict Cumberbatch, Elizabeth Hurley, and Olivia Attwood, have been caught in a significant travel disruption across the United Kingdom. The chaos stems from a failure in the air traffic control (ATC) system operated by National Air Traffic Services (NATS), which led to hundreds of flight cancellations and extensive delays on September 8 and 9, 2026.
On September 9, hundreds more flights in and out of Britain were axed, affecting an estimated 250,000 travelers at major airports including Heathrow, Gatwick, Manchester, and Stansted. Rebel Wilson, who was at Heathrow, shared videos of the crowded terminals, describing the situation as "nightmare" and "Heathrow awesomeness," and indicated she was "escaping" the airport rather than departing.
Benedict Cumberbatch was observed arriving at Heathrow with luggage, seemingly attempting to catch a flight, while Elizabeth Hurley and her son Damian were also spotted at the same airport. Olivia Attwood arrived at Heathrow after attending the National Television Awards.
System Failure and Impact
NATS, the UK's air traffic control provider, experienced a major technical issue that resulted in around 1,750 flights being cancelled on September 8. By 6 a.m. on September 9, Heathrow had seen 246 cancellations, with Gatwick reporting 33. Passengers faced prolonged waits, with some sleeping on the floor at airports and others stranded on planes for hours.
Martin Rolfe, NATS chief executive, was summoned to speak with Transport Secretary Heidi Alexander. Rolfe apologized for the disruption but defended the UK's air traffic control system, stating that significant investments had been made in technology over the years. He ruled out a cyber attack as the cause and suggested the failure was a novel incident that had not occurred in NATS' 50-year history.
Airline representatives expressed frustration. Ryanair's chief operating officer, Neal McMahon, called for Rolfe's resignation, citing the disruption as a failure of NATS' backup systems, which he argued did not perform as expected. He noted that a similar issue in August 2023, also attributed to a flight planning processing failure, had caused widespread disruption, and questioned why lessons had not been learned.
Ryanair reported over 250 flight cancellations and estimated the costs to the company to be in the millions. British Airways also confirmed over 100 cancellations on September 8. McMahon stated that the UK problem, where backup systems fail to activate, is not seen in other European countries.
Passenger Experiences
Passengers shared accounts of the difficulties. Patrick Weston, who planned to fly from Heathrow to Gothenburg, described the situation as "absolute chaos" and expressed a feeling of helplessness. Clara Nguyen and Lihan Chen, students from Leeds, had their flight to Ho Chi Minh City delayed and spent the night in a self-funded Airbnb due to poor information from the airline.
Engineer Felix Abrams described his treatment as "demeaning" and criticized the lack of preparation and information provided by airport authorities. Another passenger, flying from Malaga to Manchester, experienced a lengthy delay and subsequent return to the terminal, with difficulties rebooking and retrieving luggage, leading to a "nightmare" scenario concerning medication and work commitments.
Regulatory Scrutiny
Transport Secretary Heidi Alexander was expected to address Members of Parliament regarding the Civil Aviation Bill. NATS indicated that its systems were back to normal operation, but acknowledged the significant knock-on effects for travelers. The company committed to a thorough investigation into the incident. Passengers affected by cancellations or significant delays are entitled to assistance, including food, drink, and accommodation if an overnight stay is required, as well as refunds or rebooking options, according to UK consumer law, though claims for compensation may be limited if the cause is deemed outside airline control.
