A technical failure in the United Kingdom’s air traffic control system operated by National Air Traffic Services (NATS) caused a multi-hour outage on Tuesday, September 8, 2026. The disruption led to the cancellation of approximately 2,000 flights across major airports including London Heathrow, Gatwick, Stansted, and Manchester, impacting more than 330,000 passengers.
Ongoing Delays and Cancellations on September 9, 2026
Flight operations resumed on Wednesday, September 9, but the UK aviation network continued to experience delays and cancellations. According to Cirium, 291 additional flights were canceled on the second day, with main airports such as Heathrow reporting persistent disruptions. Airlines have been repositioning aircraft and crews, prolonging recovery
efforts.
Airlines Report Major Impact and Passenger Disruptions
Ryanair canceled over 50 scheduled flights on September 8 and reported that 65,000 of its passengers were affected, leading to immediate losses estimated at $4.06 million. British Airways cancelled more than 190 flights due to the outage. Air India confirmed multiple flights to and from UK airports were diverted, delayed, or canceled, while Qatar Airways warned of possible re-routing and delays. Wizz Air publicly criticized NATS, describing it as “simply not fit for purpose” after repeated failures.
Official Responses and Investigation Calls
NATS CEO Martin Rolfe apologized and stated that operations were stable by Wednesday, promising a full investigation into the outage. UK Transport
Secretary Heidi Alexander met with Rolfe on September 9, expressing “significant concerns at the scale of disruption” and requesting an investigation. Airlines UK’s chief executive wrote to the Transport Secretary emphasizing concerns over the NATS system failure. Ryanair’s COO Neal McMahon demanded Rolfe’s resignation, blaming repeated NATS failures for passenger hardships.
Passenger Experiences and Compensation
Passengers endured long waits and cancellations, with some forced to sleep on airport floors due to fully booked hotels near Heathrow. One traveler described the experience as “the single most stressful and disappointing” transport event. Another, stranded at Gatwick, compared navigating the airport to escaping “Alcatraz.” Airline staff received
praise for their assistance amid the chaos. Passengers affected by the disruption may qualify for refunds or compensation under UK Civil Aviation Authority rules, depending on airline policies.
History of Air Traffic Disruptions in UK
This September 8 outage follows several recent major incidents in UK airspace management, including a significant NATS system glitch in 2023 and a global IT software failure in 2024 that caused delays worldwide, including UK airports. In 2023, Heathrow faced a shutdown after a nearby fire triggered a power outage, resulting in extensive travel chaos and losses estimated in the hundreds of millions of pounds. The repeated nature of these incidents underlines
ongoing challenges in UK air traffic control infrastructure.
