'No lessons have been learned': Airlines furious after another technical glitch cancels flights

Airlines have reacted furiously after a technical glitch in air traffic control systems led to more than 150 flight cancellations.

The National Air Traffic Service (NATS) has apologised for the IT problems - and said systems were back up and running 20 minutes after the "radar-related issue" was detected at 4.05pm.

But with thousands of passengers suffering extensive travel disruption, during one of the busiest times of the year, airline executives have warned this isn't good enough.

Ryanair's chief operating officer Neal McMahon has called for NATS chief executive Martin Rolfe to resign - and claimed Wednesday's incident was "utterly unacceptable".

He said: "It is outrageous that passengers are once again being hit with delays and disruption due to Martin Rolfe's continued mismanagement of NATS.

"It is clear that no lessons have been learnt since the August 2023 NATS system outage, and passengers continue to suffer as a result of Martin Rolfe's incompetence."

Mr McMahon was referring to a glitch that affected more than 700,000 passengers two years ago - and said that, if Mr Rolfe refuses to step down, the government should intervene.

"Heidi Alexander must act without delay to remove Martin Rolfe and deliver urgent reform of NATS' shambolic ATC service, so that airlines and passengers are no longer forced to endure these preventable delays caused by persistent NATS failures," he added.

The Department for Transport says Ms Alexander does not have any direct control over NATS - and no powers over staffing decisions at the service.

EasyJet's chief operating officer David Morgan added: "It's extremely disappointing to see an ATC failure once again causing disruption to our customers at this busy and important time of year for travel.

"While our priority today is supporting our customers, we will want to understand from NATS what steps they are taking to ensure issues don't continue."

NATS is yet to comment on the calls for Mr Rolfe's resignation - but has stressed that the glitch is not believed to be "cyber related".

"This was a radar-related issue which was resolved by quickly switching to the back-up system during which time we reduced traffic to ensure safety," a spokesperson had said.

Departures at airports across the country have now resumed - but passengers are being urged to check with their airline before heading to terminals.

John Carr, from Stourbridge, was on his way from Heathrow to Norway to help arrange his brother's wedding when he discovered his flight was cancelled after checking in.

"I'm pretty gutted," he said. "We've got loads of stuff in the suitcases to set up the venue, because we're obviously flying to Norway. We've got the wedding rehearsal to do. It's quite stressful."

Liberal Democrat leader Sir Ed Davey called for an urgent investigation and also referred to the "utterly unacceptable" disruption two years earlier.

"With thousands of families preparing to go on a well-earned break, this just isn't good enough. The public deserve to have full confidence in such a vital piece of national infrastructure."

Flights departing or arriving at a UK airport, or aircraft operated by a UK airline arriving in the EU, are subject to rules concerning delays or cancellations.

Airlines may have to provide compensation, although there are exemptions for "extraordinary circumstances", according to the UK's Civil Aviation Authority.
