Passengers travelling through Manchester Airport and other major UK hubs have faced new disruption after another air traffic control problem triggered widespread delays, prompting Prime Minister Andy Burnham to describe the situation as involving “serious issues” that require full investigation.

Andy Burnham vows full probe after UK flight disruption

Fresh disruption hits Manchester and key UK airports

Flights from Manchester Airport were among those affected on Monday after National Air Traffic Services reported a technical issue at one of its Scottish centres, leading to restrictions on the flow of aircraft and knock-on disruption across the network. Published coverage indicates the problem was first reported shortly after 9:30 a.m., with delays continuing well into the day even after systems were restored.

Services at airports across northern England and Scotland were particularly impacted, alongside some routes into London. Airlines reported holding departing aircraft on the ground and diverting or delaying inbound services while air traffic controllers reduced capacity to maintain safety.

According to media reports, this is the second significant air traffic control incident within a matter of weeks, following a major outage earlier in September that led to more than 2,000 cancellations and severe disruption at hubs including Manchester, Heathrow, Gatwick and Stansted. The recurrence has intensified scrutiny of the resilience of the UK’s airspace management systems.

Passengers at Manchester described long queues, limited information and missed onward connections as airlines and airport staff attempted to rebook services and manage crowding in departure lounges. Some travelers were advised to return home or seek hotel accommodation while they waited for alternative flights.

Burnham highlights “serious issues” and orders closer scrutiny

Speaking to journalists while en route to New York for the United Nations General Assembly, Andy Burnham addressed the latest disruption and the performance of National Air Traffic Services, in which the UK government holds a significant stake. According to reports, Burnham said the situation involved “serious issues” that must be fully investigated and signalled that the transport secretary had been tasked with examining the causes and ensuring accountability.

Published coverage indicates that the head of NATS is now facing renewed calls to resign from some airline leaders and opposition figures, who argue that repeated outages are unacceptable during a busy travel period. Burnham has so far stopped short of directly backing such demands, instead emphasising the need for a thorough technical and operational review.

The renewed focus on air traffic control resilience comes as Burnham, the former mayor of Greater Manchester, seeks to demonstrate that his government can improve the reliability of critical infrastructure affecting regional economies. Manchester Airport, one of the country’s busiest outside London, is a key gateway for northern England and a major employer in the region.

Publicly available information shows that previous incidents at NATS have already prompted questions in Parliament about investment in systems, staffing and contingency arrangements. The repetition of serious faults within a short time period is likely to feature prominently in upcoming debates about funding, oversight and the balance between public and private interests in UK aviation.

Software defect blamed for earlier chaos across UK skies

The latest disruption follows closely on an internal investigation into a separate air traffic control failure on 8 September, which caused extensive delays and cancellations across the UK and affected hundreds of thousands of passengers. According to an initial report cited by broadcasters and national media, that incident was traced to a software defect in the system that allocates codes to individual aircraft flight plans.

The defect is reported to have corrupted flight data in a fraction of a second, forcing controllers to halt automatic processing and revert to manual procedures. While the technical issue was resolved within several hours, the resulting congestion cascaded through the network and left aircraft and crews out of position for the rest of the day and into the following morning.

Manchester Airport was among the airports hardest hit, with passengers facing long waits, missed holidays and rebooked trips at short notice. Airlines were required to reorganise rosters and aircraft rotations, with some carriers choosing to cancel entire rotations to restore schedules.

The proximity of the September outage to the latest issue has raised concerns among travelers, industry groups and consumer advocates about whether underlying problems have been fully addressed. Critics have argued that passengers should not bear the brunt of repeated technical failures in critical national infrastructure.

Passenger rights, compensation and what travelers can expect

Following the early September outage, the UK Civil Aviation Authority issued a statement reminding passengers and airlines of their rights and responsibilities under existing regulations. Public guidance from the regulator explains that travelers whose flights are delayed or cancelled may be entitled to care, assistance and, in some cases, financial compensation, depending on the cause and length of the disruption.

The Civil Aviation Authority notes that airlines must provide food and drink vouchers, access to communication and hotel accommodation where necessary when passengers are stranded for extended periods. Where flights are cancelled, passengers are usually entitled to a full refund or re-routing at the earliest opportunity or at a later date at the traveler’s convenience, subject to availability.

Compensation payments for delays and cancellations depend on factors including flight distance, the length of the delay on arrival and whether the cause is considered to be within the airline’s control. The regulator’s published advice stresses that technical issues at an air traffic control provider may fall outside airlines’ direct responsibility, which can affect eligibility for compensation, though basic care and assistance obligations still apply.

Travelers affected by the latest delays at Manchester and other UK airports are being advised by consumer bodies to keep detailed records of boarding passes, booking confirmations, receipts and any written communication from airlines. This documentation can support later claims for refunds, rerouting costs or compensation where applicable.

Air traffic resilience questioned as peak travel seasons approach

The succession of incidents has brought renewed scrutiny to the robustness of the UK’s air traffic control systems at a time when passenger numbers are returning to or surpassing pre-pandemic levels. Industry analysts cited in recent coverage suggest that increasing traffic, tighter airline schedules and growing dependence on complex software are combining to leave little margin for error.

For Manchester, which has invested heavily in terminal upgrades and expanded long-haul services in recent years, reliable airspace management is central to plans to attract more international routes and support tourism and business travel across the north of England. Persistent disruption risks damaging confidence among carriers and passengers choosing between regional gateways.

Burnham’s comments indicate that the government is likely to treat the latest outage not as an isolated glitch but as part of a wider pattern that must be addressed through regulatory oversight, technical investment and contingency planning. Future announcements from the Department for Transport and the Civil Aviation Authority are expected to focus on timelines for remedial work, testing regimes and the transparency of reporting around system failures.

In the meantime, airlines and airports are urging passengers to check the status of their flights before travelling, to allow extra time at terminals in case of residual delays, and to familiarise themselves with their rights in the event of further disruption. With the busy autumn and winter travel periods approaching, the performance of the UK’s air traffic system will remain under close watch from both the aviation industry and the travelling public.
