About 2,000 flights were cancelled across key UK airports on September 8, 2026, with 1,750 cancellations on Tuesday alone and an additional 291 on Wednesday. More than 330,000 passengers were affected by the disruptions at Heathrow, Gatwick, Stansted and Manchester airports.
Air Traffic Control System Failure Confirmed
The cancellations resulted from a system issue at National Air Traffic Services (NATS), the UK’s air traffic control provider. NATS confirmed the cause as a technical failure and issued an apology to passengers, airlines and airports. Operations stabilized on September 9, 2026, as efforts to recover continued. UK authorities ruled out cyberattack as a cause and said a full
investigation would be conducted.
Airline Impact and Financial Losses
Ryanair cancelled over 50 flights on September 8, disrupting approximately 65,000 passengers and suffering immediate losses estimated at $4.06 million (£3 million). British Airways cancelled more than 190 flights due to the outage. Other airlines such as Air India and Qatar Airways also reported delays, diversions and cancellations affecting flights to and from UK airports.
Government Response and Accountability Demands
UK Transport Secretary Heidi Alexander met with NATS CEO Martin Rolfe on September 9, expressing “significant concerns at the scale of disruption” and requesting a thorough investigation of the failure. Ryanair’s COO Neal McMahon called for Rolfe’s resignation, citing repeated failures
by NATS that have disrupted UK travellers in recent years. Rolfe apologized for the outage but defended NATS as fit for purpose.
Passenger Experience and Stranded Travellers
Thousands of travellers faced long delays and cancellations amid chaotic airport conditions. Healthcare worker Josie Donoghue described her experience stuck for three hours on a Gatwick runway before her Ryanair flight to Ireland was cancelled, calling it “an absolute nightmare.” A family travelling from Santorini to Connecticut was stranded overnight at Heathrow after nearby hotels were fully booked, forcing them to sleep on the airport floor. British Airways offered some passengers replacement itineraries requiring multiple connecting flights for
short journeys.
Context of Recent UK Airport Disruptions
This incident follows a pattern of major outages across UK airports in recent years, including a significant NATS technical glitch in August 2023 that led to hundreds of cancellations and a major power outage at Heathrow in 2024. NATS continues to cooperate with airlines and airports to restore normal operations while investigating the root cause of the latest failure.
