UPDATE: Airlines want action amid another UK air traffic control issue

Airlines have demanded urgent action after a second air traffic control issue in the UK in less than two weeks caused further flight disruption.

Flights have been delayed in Scotland, Northern Ireland and northern England amid an air traffic control issue on Monday, National Air Traffic Services, Nats, said.

The company said the issue was unrelated to a software fault at Nats on September 8, which caused more than 2,000 flights to be cancelled, disrupting hundreds of thousands of passengers.

Airports in Edinburgh, Belfast and Manchester were registering delayed flights and urged passengers to check with their airlines.

A Nats spokesperson said Monday's incident had been caused by an issue at its Prestwick centre in Scotland, which has since been fixed.

Airlines including Ryanair Holdings PLC have previously called for the resignation of Nats Chief Executive Martin Rolfe after the flight chaos earlier this month.

easyJet PLC has said the latest flight disruption "calls into question the resilience of Nats' systems", and Jet2 PLC said customers and airlines need "action, accountability and proper resilience".

"This, once again, calls into question the resilience of Nats' systems and demonstrates the need for firm actions to prevent these repeated failures," easyJet said on Monday.

"We will do all we can to minimise the impact of this for our customers and advise anyone due to fly today to check our flight tracker for the latest information."

Jet2 Chief Executive Steve Heapy said: "This morning's disruption comes days after Nats published a report into its latest major failure and it is simply not good enough for this critical national infrastructure to keep letting customers down.

"Customers work hard to look forward to their holidays and airlines work hard to deliver those holidays. They should not be repeatedly exposed to delays and disruption because the UK's air traffic control systems cannot be relied upon.

"There have been too many incidents, too many reports and too many promises of lessons being learned.

"What customers and airlines need now is action, accountability and proper resilience, and we need it urgently."

He added: "Make no mistake, we are counting the cost of this disruption and will be sending another bill to Nats."

British Airways said it was "disappointing" that some customers may experience disruption after "yet another technical fault with Nats".

Nats said airports south of Manchester had been "broadly unaffected" on Monday, but that flights heading north and departing from Scottish airports had been experiencing some delays.

"Passengers should check with their airlines. This is unrelated to the issue two weeks ago. We apologise for the disruption," Nats said.

Transport Secretary Heidi Alexander said in a post on X that engineers had "fixed the problem and systems are resuming", but some delays may continue during the reset.

A Nats spokesperson said: "The issue in our Prestwick centre is now fixed. We are working with airports and airlines to safely lift air traffic regulations as quickly as we can to minimise any further disruption.

"Passengers should still check the status of their flight with their airline. We apologise for the disruption."

Nats is the UK's leading provider of air traffic control services and handles about 2.5 million flights per year.
