British Airways cancels hundreds of flights following UK air traffic control outage
British Airways has cancelled hundreds of flights across two days following a critical NATS technical failure that disrupted UK airspace.
British Airways has cancelled hundreds of flights following a major air traffic control technical failure across the UK, leaving tens of thousands of passengers stranded and spilling over into a second day of heavy disruption.
The travel chaos erupted after a technical issue struck NATS, the public-private company that oversees air traffic control in Britain from its facility in Swanwick, Hampshire. The NATS Swanwick operations room manages en-route airspace over England and Wales up to the Scottish border, alongside lower-altitude traffic connecting to London airports. According to Business Insider Africa, the meltdown grounded thousands of flights worldwide and left terminal waiting areas congested as aircraft were held at departure gates or forced to divert.

British Airways said it scrapped about 550 flights across the affected days, affecting more than 85,000 passengers. Because the British flagship carrier runs a large long-haul schedule primarily out of London Heathrow Airport, its recovery timeline has been significantly more complex than those of its competitors. Aircraft stuck across Europe and beyond found it difficult to return due to a lack of ad-hoc landing slots, compounding schedule pressures.
The scale of disruption varied widely across carriers and airports, as illustrated in the operational breakdown below:
| Airline / Airport | Cancellations & Impact (Day One) | Cancellations & Impact (Day Two) |
|---|---|---|
| British Airways | Over 100 flights cancelled or diverted | About 200 flights cancelled |
| Ryanair | Over 50 flights cancelled; 65,000+ passengers disrupted | Zero cancellations reported by carrier |
| EasyJet | Widespread schedule delays and cancellations | About 30 cancellations reported |
| London Heathrow | Hundreds of flights grounded; arrivals temporarily restricted | Ongoing knock-on delays and repositioning bottlenecks |
Government figures moved swiftly to address the systemic failures. Transport Secretary Heidi Alexander summoned NATS chief executive Martin Rolfe to discuss the IT failure and deliver a strict one-week deadline for a comprehensive investigation. While the government ruled out a cyberattack, aviation executives expressed furious opposition. Ryanair chief executive Michael O'Leary labelled Rolfe an overpaid failure, while Wizz Air managing director Yvonne Moynihan questioned the long-term resilience of the national infrastructure after multiple high-profile breakdowns in recent years.
Defending his record during interviews, Rolfe stated that investigators had ruled out external malicious activity and insisted that the UK maintains one of the safest and most advanced air traffic networks in the world. He noted that engineers successfully implemented a system fix, allowing airspace to reopen and controllers to focus on clearing the massive backlog of delayed services.
Airlines and airports continue to urge all affected travellers to verify their flight statuses directly with operators before traveling to terminals. Passengers experiencing prolonged waits are entitled to statutory care provisions under aviation rules, including refreshments, meals, and overnight hotel accommodations where necessary, while industry regulators monitor the slow return to normal operating schedules.
