9/10/2026, 11:03:36 AM
Core Event
On September 8 2026 a technical fault in the flight-processing system of National Air Traffic Services (NATS) halted departures and arrivals at Heathrow, Gatwick, Manchester and Stansted. The outage was declared resolved by 7:30 p.m. on September 9, but a backlog of aircraft, crews and passengers extended disruption into the following day.
Data & Statistics
- Flight cancellations: reports range from 1,300 to over 2,000 flights cancelled across the two days.
- Airlines affected: British Airways, Virgin Atlantic, easyJet, Ryanair, KLM and Eurowings.
- Passenger impact: hundreds of thousands stranded, with many sleeping on airport floors or in nearby pubs, and numerous diverted flights landing at alternate cities.
Timeline
- September 8: NATS alerts a “technical issue” in its flight-processing system; cancellations begin.
- September 9: NATS announces the problem is resolved; Heathrow and Gatwick resume operations but warn of knock-on effects.
- September 9: Transport Secretary Heidi Alexander meets NATS chief Martin Rolfe and requests a full investigation.
Official Statements & Responses
- NATS spokesperson said the fault was unrelated to the 2023 system failure and pledged a full investigation.
- Gatwick Airport warned that normalisation would take time.
- British Airways called the incident “entirely out of our control” and said it had rebooked more than 60,000 customers.
- Virgin Atlantic apologised for the “widespread disruption” and thanked passengers for their patience.
Criticism & Opposition
- Ryanair COO Neal McMahon called for the removal of NATS chief Martin Rolfe, labeling the failure a “catastrophic system collapse.”
- Wizz Air’s spokesperson said NATS is “simply not fit for purpose” and urged urgent reform.
On-the-Ground Reports
Passengers described “nightmare delays” and “chaos.” Sasha, a newly-wed traveler, spent three hours in a Wetherspoons pub after her Gatwick flight to Madeira was cancelled. Others slept on airport floors, in hotel conference rooms or on tarmacs, while baggage reclaim areas were overwhelmed.
Conflicting Reports & Gaps
Sources differ on the exact scale of cancellations: CNBC cites 1,300 flights, The Guardian reports over 2,000, and The New York Times mentions 1,700. No single source provides a definitive total, and airlines have not released a consolidated figure. NATS has ruled out a cyber-attack, but the precise technical trigger remains undisclosed pending investigation.
