A technical failure within the United Kingdom's air traffic control system has resulted in the cancellation of over 2,000 flights and caused widespread disruption for a second consecutive day. The issues, attributed to a problem in the flight processing system by NATS (formerly National Air Traffic Services), have impacted 15 U.K. airports and led to significant backlogs.
Delays continued throughout Wednesday as airlines worked to rebook stranded passengers and reposition aircraft that were left at incorrect airports. The original technical issue was reportedly resolved Tuesday afternoon, but the ripple effects continued, leaving passengers facing extended waits and uncertainty.
Airlines expressed frustration over the incident, with some demanding the resignation of NATS chief executive Martin Rolfe, citing this as the second major air traffic meltdown in three years. U.K. Transport Secretary Heidi Alexander met with Rolfe and has given him one week to complete a full investigation into the cause and ensure lessons are learned. The government, which is the largest shareholder in the public-private partnership NATS with a 49% stake, stated that Rolfe retains their confidence.
Rolfe apologized for the inconvenience, emphasizing the paramount importance of safety. "Our job is also to make sure that people stay safe," he told the BBC. "We never do this lightly. We only ever do it when there is an issue that cannot be resolved quickly, and we have to take action to make (sure) those who are flying, who are in the air at that time, are safe. And when we can restore these incredibly complex systems we do so as quickly as we can."
Passengers described chaotic scenes and a lack of information. Charlie Adlard, a cartoonist traveling to Sicily, recounted attempting to reach British Airways for hours without success due to high call volumes. "Due to the lack of information, due to everything crashing now, due to the fact that apparently BA have now switched off their customer service phone number because there’s so many calls, we’re not really sure what to do," Adlard said. After losing a day of travel and incurring additional expenses for a hotel, he decided to return home, describing the journey as "wasteful."
At airports like Gatwick and Heathrow, passengers were seen sleeping on floors and gathering around information boards. Heathrow Airport advised travelers to check flight status before departing for the airport and to only travel if their flight was confirmed. The airport stated it has deployed extra staff to assist passengers while working with NATS and airline partners to restore normal operations.
