Heathrow and Gatwick delays live: Hundreds of flights grounded at UK airports due to air traffic control glitch

Passengers at major UK airports including Heathrow and Gatwick faced significant travel disruptions due to a technical issue with the air traffic control system. The National Air Traffic Control Service (Nats) reported that engineers identified and resolved the problem within two hours, though it remained unclear how long it would take for operations to fully stabilize. Multiple airports across the UK, including Birmingham, Manchester, and several in Scotland and Northern Ireland, reported flight delays and cancellations affecting approximately 4% of UK flights. Experts noted that while the immediate issue was addressed, further cancellations could occur as airlines adjust schedules to manage the backlog. Airlines advised passengers to check directly with their carriers for the most up-to-date flight information.

Around 300 flights have been cancelled or delayed across major UK airports due to a technical failure in the National Air Traffic Services (NATS) system, causing widespread disruption. Passengers at Heathrow, Gatwick, Manchester, Birmingham, and other airports face hours of delays, with some flights remaining grounded well into the evening. The issue, traced to a problem in NATS’s flight processing system, has led to significant travel chaos, particularly affecting holidaymakers and business travellers. NATS confirmed that engineers had identified the problem and implemented a fix, though it warned that recovery would take time. The organisation stated that flights are still departing and airspace remains open, but the system is only beginning to stabilise. Heathrow initially reported that only departures were affected, but later confirmed that both arriving and departing flights were impacted. The airport urged passengers to check with their airlines for the latest information and to avoid heading to the airport unless their flight was confirmed. The disruption has affected more than 10 UK airports, including Heathrow, Gatwick, Manchester, Birmingham, Aberdeen, Edinburgh, Glasgow, Nottingham, Bristol, London Stansted, and London City. According to Flightradar24, approximately 4% of UK flights have been cancelled or delayed, with 352 flights from Heathrow and 281 from Gatwick affected. Manchester and Birmingham also reported significant delays, with 249 and 101 flights respectively impacted. Ryanair, which has been particularly vocal about the issue, stated that over 65,000 of its passengers have been delayed for up to eight hours, with more than 50 flights cancelled. The airline called for the resignation of NATS CEO Martin Rolfe, accusing him of overseeing a “repeated failure” of the UK’s air traffic control system. Other airlines, including Wizzair, have echoed similar criticisms, stating that NATS is “simply not fit for purpose in its current form.” The airline noted that the disruption has extended beyond the UK, with some inbound flights from continental Europe being held on the ground and affecting international connections. One passenger flying from Dublin to Malta described being informed of an “issue in London” without specific details on departure times or expected delays. Social media posts from stranded passengers highlight the frustration, with some reporting being stuck on planes at airports such as Luton and Alicante. NATS, which is 49% government-owned, has previously experienced major outages. In August 2023, a malfunction in its automated flight planning system caused widespread disruption, affecting over 700,000 passengers. The incident led to a parliamentary inquiry and increased scrutiny of the organisation’s reliability. This latest failure follows a pattern of repeated issues, prompting calls for systemic reform and leadership changes within NATS. Several UK airports have issued statements advising passengers to check with their airlines for real-time updates. Newcastle Airport noted that while some departures were delayed, the impact was less severe compared to southern airports. Meanwhile, Belfast’s two airports warned of potential disruptions, urging passengers to monitor flight statuses. Heathrow and Manchester airports have advised passengers to arrive in line with their airline’s check-in requirements and to stay in touch with their carriers for updates. The disruption has raised concerns about the stability of the UK’s air traffic control system. Transport Secretary Heidi Alexander acknowledged the frustration caused to passengers and expressed regret for the inconvenience. She reiterated that the government was aware of the situation and was working to address it. NATS has pledged to provide regular updates via its website and social media platforms, but the full extent of the disruption and the timeline for full recovery remain unclear. As the situation unfolds, airlines and passengers continue to navigate the fallout of the technical failure, with many seeking reassurance and compensation for the extensive delays and cancellations. The incident underscores the growing pressure on NATS to improve its operational reliability and ensure that such disruptions do not recur.
