Higher is stronger
The headline uses 'tens of thousands' which is supported by airline statements, but the overall tone is measured.
Lower is better
On Tuesday, NATS confirmed that a technical problem in its flight‑processing system triggered the cancellation of 425 flights to and from UK airports by 5 pm, according to flight‑tracking data. The disruption hit Heathrow and Gatwick most severely, leaving thousands of travellers stranded.
Technical fault in NATS system
Gatwick Airport runway closed due to departing aircraft issue
Flights were suspended and some diverted as a technical problem with a plane halted operations.
NATS issued a statement saying the issue lay within its central processing software, which stopped the normal flow of flight plans. The provider added that a fix had been applied and the system was beginning to recover. The agency apologised to passengers and urged them to check with their airlines for updated information.
Airlines' operational response
Ryanair told the Press Association that more than 65,000 of its customers were impacted and that it had cancelled more than 50 scheduled services. British Airways announced that it had to cancel or divert over 100 flights, describing the situation as "entirely out of our control" and "incredibly frustrating for our customers and colleagues". EasyJet confirmed that a number of its flights could not operate, adding that the glitch caused delays across Europe.

Effect on London travellers
Heathrow and Gatwick serve the capital’s commuter belt, so the cancellations disrupted business trips, holiday plans and airport‑link services for residents of Barnet and surrounding boroughs. Passengers reported long queues, last‑minute gate changes and, in some cases, overnight stays at the airports while awaiting re‑booking.
