National Air Traffic Services investigates technical issue impacting flights from Heathrow and Gatwick.

NATS, which provides air traffic control for 15 UK airports, confirmed the technical issue on Tuesday evening. While the system was reported as resolved around 7:30pm, NATS stated that recovery was taking longer than anticipated. Heathrow Airport announced that arrivals were suspended for the remainder of the day to ensure safety, although departures had resumed. Passengers were advised to check with their airlines for the latest information before travelling.

Flight tracker Flightradar indicated that almost 400 flights to and from London airports were cancelled, with an additional 750 delayed. Stansted, London City, and Luton airports also reported numerous delays and cancellations. Passengers described scenes of long waits on the tarmac and anxious queues for updates, with some facing overnight stays at airports.

Passengers faced lengthy delays and were stranded on aircraft due to an air traffic control system issue.

Major airlines reported substantial disruption. Ryanair stated that over 65,000 passengers were affected, with more than 50 flights cancelled. British Airways confirmed that over 100 flights were cancelled or diverted, impacting tens of thousands of customers. A spokesperson for British Airways noted that despite the system being resolved, the severity of the incident would cause significant ongoing disruption.

EasyJet also confirmed that some of its flights were unable to operate, contributing to delays across Europe. Transport Secretary Heidi Alexander stated she was seeking assurances that lessons would be learned from the incident and that aviation support systems were adequate for the task.

Previous Incidents and Future Concerns

This incident follows previous air traffic control failures. In July of the previous year, a radar-related issue caused widespread disruption, grounding flights and leading to over 160 cancellations. In August 2023, a technical glitch in NATS's flight plan processing affected hundreds of thousands of passengers.

The exact cause of Tuesday's fault remains unknown, and it is unclear how long the backlog will take to fully clear. However, the expectation is that disruption will continue into Wednesday, affecting travellers with onward journeys.
