UK airports face chaos as Nats system failure disrupts thousands of flights

Airports across the United Kingdom experienced significant operational disruption after a technical failure in the national air traffic control system. More than 2,000 flights were cancelled following the incident, which originated on Tuesday. Although Nats, the air traffic control provider, stated that the problem was resolved within hours, the aftermath continued to affect hundreds of thousands of passengers on Wednesday through further delays and cancellations. Martin Rolfe, the chief executive of Nats, has been instructed to submit a report detailing the causes of the failure within one week.

Travellers affected by the two-day disruption have described severe difficulties, ranging from prolonged waits on aircraft to sleeping on airport floors. Daniel Garrick, a 32-year-old software engineer, was scheduled to depart Heathrow for Austin, Texas, on Tuesday. He reported spending seven hours on the tarmac before being released from the plane into what he described as absolute chaos. Garrick stated that his baggage was lost and that British Airways staff were difficult to locate. He noted that passengers were sleeping on every available surface in arrivals and security areas. Baggage reclaim was described as pandemonium, with screens indicating the area was closed and no information available regarding luggage locations. Garrick eventually discovered, with the help of other passengers, that his bags remained on the aircraft. An announcement indicated that staff would not finish removing bags that night, leaving passengers to depart without their luggage. At the time of reporting, Garrick had not yet retrieved his case, which contained a week’s worth of clothing. British Airways sent a mass email apology on Tuesday evening and automatically rebooked him for a flight the following morning, 48 hours after his original departure. He incurred additional costs for transport to accommodation in Surrey.

Melanie Thompson, a 71-year-old artist, was returning from Tokyo with her son when her flight was diverted to Edinburgh due to IT problems at Heathrow. The pilot informed passengers approximately 40 minutes before arrival that they would have to divert. Initially, there was hope to refuel and continue to Heathrow, but this was not possible. Thompson and her son were left to arrange their own travel and accommodation in Edinburgh. They found that hotels and short-term rentals were fully booked and eventually secured a flat for £500 for the night. Thompson spoke to the Guardian while travelling by train from Edinburgh to London on Wednesday, as no flights were available.

Thomas Reilly, a 55-year-old freelance geopolitical adviser, was due to fly from Marrakech to Gatwick and then to Marseille. He was informed of the cancellation only upon arriving at the airport, stating he received no prior information from British Airways. Although airport staff were described as helpful, Reilly was left to book a hotel for two additional nights at his own expense. He reported difficulties contacting British Airways customer services, with phone lines busy and chatbots unable to assist. Reilly stated that the airline would not refund his ticket for the cancelled leg of the journey. He has arranged alternative travel for Thursday, 10 September, but is seeking a refund before paying for the replacement flight.

Keith Sessions, a 74-year-old computer engineer, and his wife were due to fly from Heathrow to Tahiti via Los Angeles. They were on a Virgin Atlantic flight for the first leg when the pilot announced delays. After five and a half hours on the tarmac, the flight was cancelled. Sessions stated that the couple were offered only water, soft drinks, and snacks during the wait. They returned home by taxi and had their flights automatically rebooked for Thursday. The new itinerary includes an 11-hour stopover in Los Angeles, with arrival in Tahiti at 05:30 on Friday. Sessions noted the loss of two days of their trip and additional costs of £340 for transport and seat reservations. He described communication from Virgin Atlantic as poor.

British Airways said it had rebooked more than 60,000 customers on alternative flights and was operating almost 80% of its schedule. The airline apologised for the disruption, attributing it to an issue entirely out of its control. Virgin Atlantic also issued a sincere apology to customers for the widespread disruption and acknowledged the frustration caused by delays and changes to travel plans.
