UK flights resume but airports warn of ongoing disruption from air traffic outage

LONDON, Sept 9 (Reuters) – Flights from British airports resumed early on Wednesday after a major air traffic control failure, but hubs warned ​that it would take time for operations ‌to return to normal after disruption left aircraft in the wrong places.

The hours-long shutdown on Tuesday, which resulted in the cancellation of more than 1,000 flights and left ‌hundreds ​of thousands of passengers stranded, ⁠has ramped up pressure ⁠on air traffic control provider NATS and its boss Martin Rolfe.

Ryanair, Europe’s biggest airline, had already called for him to resign for his role ​in the last system meltdown in August 2023, when cancelled flights cost operators £100 million ($135 million).

As ⁠operations restarted, Heathrow Airport, near ⁠London, said passengers should check with ​their airline before heading to the airport as schedules ​would have changed due to the problems ‌on Tuesday.

“We are expecting knock-on impacts as aircraft and crew reposition,” the UK’s busiest hub said in a statement.

“We know how frustrating this situation is ⁠and … are working closely with our local NATS team and airline partners to recover normal operations as quickly ⁠as possible.”

London ‌Gatwick, Britain’s second busiest airport, also ⁠advised passengers to check with their airline ​first.

Ryanair ‌said around 150,000 of its passengers ​had been ⁠affected by the outage after it cancelled more than 200 flights, while British Airways said it had cancelled or diverted 100 flights with tens of thousands impacted.
