Air traffic control system fails in Britain:425 flights cancelled, several airlines including British Airways and easyJet affected

A technical failure in the UK’s air traffic control system triggered widespread disruption across the country on Tuesday, forcing airlines to cancel hundreds of services and causing delays at major airports throughout Britain and Europe. According to flight-tracking platform Flightradar24, nearly 425 flights were cancelled as the issue affected the operation of departing aircraft. The disruption spread across multiple airports and airlines, leaving passengers facing delays and last-minute schedule changes. Air Traffic System Hit by Technical Problem Britain’s National Air Traffic Services (NATS) confirmed that engineers were working urgently to resolve a fault affecting flight operations. The problem primarily impacted departing flights, prompting air traffic authorities to introduce restrictions while technical teams attempted to restore normal service. Later in the day, NATS announced that a solution had been implemented. “Our flight system is starting to recover,” the organisation said in an update, while apologising to passengers and airlines for the disruption caused. However, the effects of the outage continued to be felt across the aviation network as carriers worked to reposition aircraft and clear backlogs created by the interruption. Major airports affected Several of the UK’s busiest airports reported operational difficulties linked to the air traffic control failure. In London, Heathrow, Stansted and London City Airport warned passengers that the technical issue was causing disruption to flight schedules. Airports in Manchester, Birmingham, Scotland and other parts of the UK also reported delays and operational challenges. Airport authorities urged travellers to check directly with their airlines before heading to terminals, warning that schedules could continue to change as systems recovered. Airlines face delays and cancellations Flightradar24 said the disruption affected dozens of flights operated by a range of major European carriers, including British Airways, EasyJet, KLM and Lufthansa. Budget airline EasyJet confirmed that some of its services were unable to operate because of the system failure. The airline said the technical issue had caused delays not only within the UK but also across parts of Europe, highlighting the interconnected nature of the region’s air traffic network. Airlines spent much of the day adjusting schedules and managing disrupted passenger itineraries as the effects of the outage rippled through the system. Heathrow departures among worst hit Flight information published on Heathrow Airport’s website showed significant disruption to short-haul services departing for destinations across Europe. Numerous flights scheduled to leave the airport on Tuesday were either delayed or cancelled altogether. Despite the difficulties facing outbound services, arriving flights did not appear to be significantly affected by the technical problem. The distinction suggested that the issue was primarily linked to the management of departures rather than inbound air traffic. Cause yet to be determined While operations were gradually returning to normal by Tuesday evening, authorities had not immediately disclosed the cause of the system failure. NATS did not provide details about what triggered the outage, and no timeline was given for a full technical investigation. ​
