The north of England on Monday, the latest embarrassment to afflict the U.K. national air traffic controller.
Although NATS, formerly known as National Air Traffic Services, said the issue at its Prestwick center in Scotland has been fixed, the repercussions would likely continue through the day at the very least, with flights canceled or delayed.
“We are working with airports and airlines to safely lift air traffic regulations as quickly as we can to minimize any further disruption,” it said in a statement. “We apologize
for the disruption.” NATS said airports south of Manchester, including those in and out of London, are “broadly unaffected."
Manchester, Belfast International, Edinburgh and George Best Belfast City airports have seen the most disruption, according to aviation analytics company Cirium.
NATS said the disruption is unconnected with the software glitch that led to the cancellation of over 2,000 flights in and out of the United Kingdom two weeks ago. The chaos prompted mounting calls for its chief executive Martin Rolfe to stand down.
