Air traffic control issue disrupts departing flights at major UK airports
Nats said 425 flights were canceled as engineers worked to restore its flight processing system and airlines warned of more knock-on delays.
- On Tuesday, September 8, 2026, a technical fault in the flight-processing system operated by National Air Traffic Services halted departures at major UK airports, grounding hundreds of flights and causing widespread aviation chaos.
- Engineers identified the fault within the flight-processing system and implemented a fix, though NATS warned recovery would take time given the complexity of restoring service to 15 UK airports.
- Flightradar24 reported approximately 1,300 flights were cancelled on Tuesday, while Ryanair's Chief Operating Officer Neal McMahon criticized NATS CEO Martin Rolfe for "repeated mismanagement."
- Airlines continue repositioning aircraft and crews as operations gradually resume, with British Airways warning of significant knock-on impacts affecting tens of thousands of customers across its network.
- Transport Secretary Heidi Alexander is set to speak with Rolfe on Wednesday ahead of her Commons address on the Civil Aviation Bill, signalling potential legislative action to strengthen aviation infrastructure oversight.
