Fresh calls for UK air traffic chief to quit after new chaos

Britain’s top air traffic controller is under mounting pressure to resign after a second technical failure in two weeks caused widespread flight disruption across Scotland, Northern Ireland and northern England, leaving airlines furious and tens of thousands of passengers facing delays and cancellations.

Second major glitch in two weeks hits UK airspace

The latest disruption unfolded on Monday, 21 September 2026, when the UK’s national air traffic control provider NATS reported a technical issue at its Prestwick centre in Scotland. According to published coverage, the problem affected air traffic management for routes covering Scotland, Northern Ireland and large parts of northern England, forcing restrictions on airspace and prompting airlines to delay or cancel services.

Reports indicate that at least 200 flights were cancelled over the course of the day, with further knock-on delays across the network as aircraft and crews were left out of position. Services to and from airports including Glasgow, Edinburgh, Belfast International, Belfast City, Newcastle and Manchester were among those affected, with some short-haul European links also disrupted as aircraft transited UK-controlled airspace.

NATS stated that the specific fault at Prestwick was fixed later the same day, but the impact on the flight schedule continued into the evening as airlines attempted to recover normal operations. Aviation data cited in news reports showed a sharp spike in delays, particularly during the morning and early afternoon peak, before gradually easing once traffic flow restrictions were lifted.

The incident comes less than two weeks after another system issue forced significant restrictions on UK airspace, with that earlier glitch prompting cancellations and delays for hundreds of flights and affecting an estimated hundreds of thousands of travellers. Together, the two events have raised acute questions about the resilience of Britain’s air traffic control technology.

Airlines demand accountability from NATS leadership

The twin disruptions have triggered an intense backlash from airlines, which argue that repeated technical failures at NATS are inflicting avoidable costs on carriers and chaos on passengers. Published reports describe a particularly strong response from low cost giant Ryanair, which has said more than 25,000 of its passengers were affected by the latest glitch and has renewed demands for NATS chief executive Martin Rolfe to step down.

Ryanair and other carriers have publicly questioned the robustness of NATS systems, pointing to the recent sequence of incidents, including a separate software-related failure that severely disrupted flights during a summer holiday peak in 2023. Airline representatives have highlighted the costs of diversions, crew displacement and passenger care obligations whenever UK airspace capacity is suddenly curtailed by technical problems.

British carrier easyJet has also been critical, with its public statements reported as questioning the resilience of NATS technology and calling for firm measures to prevent further failures. Industry groups have urged the government to take a close look at both the technical architecture and governance of the air traffic provider, noting that airlines and passengers ultimately absorb the financial and operational fallout when systems go down.

The calls for accountability have been sharpened by recent coverage of NATS executive pay. Reports indicate that Martin Rolfe has received bonus packages worth around 2 million pounds in recent years, even as previous system outages led to thousands of cancellations and extensive disruption at major hubs including Heathrow, Gatwick, Manchester and Stansted. That contrast between performance issues and remuneration has become a focal point for critics arguing his position is increasingly untenable.

Government scrutiny and investigations into system resilience

The UK government has already ordered detailed investigations into earlier outages, including the high profile August 2023 incident that was ultimately traced to a defect in flight data processing software handling certain types of flight plans. Following that event, NATS said it had implemented mitigation measures while a permanent fix was designed and tested, stressing that safety was never compromised and that the fault related to capacity and system availability rather than direct control of aircraft.

In the wake of the latest glitches, attention is turning to whether those mitigation steps went far enough and whether additional vulnerabilities remain in the wider air traffic control network. Transport Secretary Heidi Alexander has previously required NATS to provide full technical explanations for recent incidents and to demonstrate how lessons are being applied throughout the organisation’s infrastructure.

Commentary in British media notes that although UK ministers have in past cases described individual failures as isolated incidents, the emergence of multiple problems within a relatively short period makes that reassurance more difficult to sustain. Analysts point out that air traffic control relies on complex, interlinked systems, and that faults in one centre can have disproportionate effects across the wider network if contingency capacity is limited.

For travellers, the immediate concern is how quickly flight schedules can be restored and whether additional disruption will follow. While operations largely normalised a day after the earlier September fault, the recurrence of issues so soon afterwards has prompted fresh questions about the risk of future outages during busy travel periods such as school holidays and the year end peak.

Travellers face cancellations, diversions and long waits

For passengers caught up in the latest disruption, the experience has been familiar: early morning notices of air traffic restrictions, followed by waves of flight cancellations, rolling departure boards and crowded terminals as airlines worked through revised schedules. Reports from affected airports describe passengers being advised to check with their airline before travelling, and in some cases urged to postpone journeys where possible.

Data from flight tracking services cited in news coverage shows that, in addition to outright cancellations, many flights operated with significant delays as traffic flow rates into constrained airspace were reduced. Some long haul arrivals were held in airborne holding patterns or diverted to alternative airports, further complicating airline efforts to get aircraft and crews back into the right place for later rotations.

Under UK and European air passenger rights regulations, travellers whose flights were cancelled or severely delayed due to the NATS failures are generally entitled to rebooking or refunds, as well as care such as meals and accommodation in certain circumstances. However, whether additional compensation is due can depend on legal assessments of whether the outages were considered extraordinary circumstances beyond the control of airlines, an issue that has been contested after previous system glitches.

Consumer advocates quoted in recent coverage have urged passengers to keep detailed records of boarding passes, receipts and communications from airlines in order to support any later claims. They also advise checking airline apps and official airport communications regularly, as schedules can shift rapidly during the recovery phase after large scale airspace restrictions.

What comes next for NATS and UK aviation

The mounting criticism has left Martin Rolfe facing some of the most intense scrutiny of his tenure as NATS chief executive. While he has previously stated that he accepts full responsibility when systems fail, he has resisted earlier calls to resign and has argued that the organisation is investing heavily in modernising Britain’s air traffic infrastructure and improving resilience.

Sector analysts suggest that the government now faces a difficult balancing act. On one hand, it relies on NATS as a critical national infrastructure provider responsible for the safe management of UK airspace. On the other, repeated disruptions risk damaging confidence among airlines and passengers, and could undermine the country’s reputation as a reliable aviation hub if not convincingly addressed.

In the short term, attention will focus on the technical root cause analysis of the latest Prestwick incident and whether further interim safeguards can be put in place ahead of any long term system upgrades. Industry observers will also watch closely for any changes in NATS leadership or governance, particularly if political pressure continues to build.

For now, travellers planning to fly to or through the UK over the coming weeks are being advised in public guidance and media reports to monitor airline updates closely, allow extra time at airports and be prepared for schedule adjustments, even as operations return to normal after the most recent disruption.
