Airlines are demanding immediate action and accountability following a fresh technical failure within the UK’s air traffic control network, which triggered a second wave of flight disruptions in less than a fortnight. The outage, which stemmed from a connectivity issue at the National Air Traffic Services (Nats) control centre in Prestwick, Scotland, caused significant delays and cancellations across airports in Scotland, northern England, and Northern Ireland on Monday morning.
While the fault was resolved by approximately 10.30am, the impact was severe. Analysts at Cirium project that at least 200 flights will be cancelled by the end of the day. A Nats spokesperson apologised for the disruption and confirmed they had been working to lift air traffic regulations as quickly as possible, noting that this specific incident was unrelated to the system failure that occurred two weeks ago.
Transport Secretary Heidi Alexander acknowledged the frustration caused by the outage, noting on social media shortly after the fix that while systems were resetting, some lingering delays were expected. Alexander has previously commissioned the Civil Aviation Authority (CAA) to conduct an independent review of Nats, specifically to examine the findings of an initial report into the 8 September breakdown. She stressed that the government must urgently understand why these systemic issues are not being identified and mitigated before they result in widespread travel chaos.
For many travelers, the reality of the disruption was immediate. Passengers at Glasgow Airport were left stranded, including a couple who were forced to rebook their wedding travel to Las Vegas after their British Airways flight to Heathrow was cancelled. The bride-to-be, Barbara Ann Stoddart, expressed deep concern that missing their connection would now jeopardise their wedding ceremony scheduled for Saturday.
The CAA has indicated that while airlines must continue to care for affected passengers, they are unlikely to be liable for compensation claims. A spokesperson stated that the technical failure at the Prestwick centre is likely to be categorised as an extraordinary circumstance under current passenger rights regulations, absolving carriers of financial responsibility for the cancellations.
The aviation industry remains highly critical of the situation. Ryanair has led calls for Nats chief executive Martin Rolfe to resign, with the airline’s chief operations officer, Neal McMahon, noting that the system failed just three days after the company claimed it had implemented robust mitigation plans. Ryanair reported that more than 25,000 of its passengers were affected, with over 140 flights delayed.
Other major carriers echoed these frustrations. EasyJet labelled the incident a failure of system resilience, while British Airways described the recurring faults as deeply disappointing. Jet2 chief executive Steve Heapy asserted that the current level of service for critical national infrastructure is unacceptable, insisting that the industry requires genuine accountability and long-term technical stability.
This latest incident increases pressure on Rolfe, who earned £1.4m last year including bonuses. The company has faced three major high-profile failures in just over three years. These include a “rogue flight plan” in August 2023 that stranded over 700,000 passengers, and a radar-related failure in July 2025 that led to more than 160 cancellations. Although Rolfe has apologised and accepted responsibility, Nats maintains that these individual incidents are not connected. The report also notes that there may be some delays as things reset.”. The report also notes that and I’ve got to be there three days in advance … If there’s any hiccups I might not be getting married on Saturday now.”, i have still to go to the county court in Vegas to go and get the marriage licence. The report also notes that “We consider that disruption caused by the technical issue at Nats Prestwick centre in Scotland on 21 September is likely to be considered the result of ‘extraordinary circumstances’ under passenger rights rules.
