Air traffic control systems across the United Kingdom experienced widespread technical problems on Tuesday, leading to significant disruption for thousands of travellers.
The issues were expected to persist into Wednesday as aviation operators worked to restore normal operations.
The National Air Traffic Service, which manages flight control operations for fifteen British airports, encountered the system failure that caused approximately thirteen hundred flights to and from UK airports to be cancelled.
The disruption left tens of thousands of passengers facing significant travel difficulties.
Industry observers indicated that Wednesday would bring continued problems as carriers dealt with the cascading effects of the technical malfunction.
The impact was felt at principal airports including Heathrow, Gatwick, Manchester and Stansted.
Travel expert Simon Calder suggested that Wednesday morning would see substantial cancellations, explaining that aircraft had not departed as scheduled the previous evening, meaning inbound flights would consequently be affected.
Heathrow confirmed that operations remained in a recovery phase following the incident.
The airport confirmed that services were running but acknowledged that some residual delays were likely as airlines repositioned aircraft and crew.
Passengers were advised to verify their flight status directly with their carrier before arriving at the terminal and to travel only if their booking was confirmed.
Manchester Airport indicated on Tuesday evening that it anticipated a complete flight schedule would operate on Wednesday after the technical fault was resolved by the air traffic service provider.
The facility warned, however, that increased passenger volumes could occur due to rescheduled services.
Ryanair reported that more than sixty-five thousand of its customers had experienced disruption, with the carrier cancelling more than fifty planned services as a consequence of the incident.
British Airways stated that it had been compelled to cancel or reroute more than one hundred flights on Tuesday, impacting tens of thousands of passengers.
Some travellers reported being stranded on aircraft positioned on runways for extended periods.
The chief executive of the National Air Traffic Service accepted accountability for the situation when questioned about his position.
The executive stated that as the leader of critical infrastructure, responsibility for such outcomes ultimately rested with his leadership.
The executive emphasised that safety remained the paramount concern alongside delivering the best possible service during challenging circumstances.
Attention remained focused on resolving the technical problems and assisting airline and airport partners in returning operations to normal.
The carrier faced criticism from budget airlines Wizz Air and Ryanair following the incident.
Ryanair’s chief operating officer publicly called for the air traffic service chief to resign, citing what he described as repeated failures and mismanagement.
The executive pointed to an earlier significant system failure in 2023, suggesting that inadequate improvements had been implemented and passengers continued to suffer avoidable delays of up to eight hours as a consequence of system breakdowns.
The Transport Secretary was scheduled to meet with the air traffic service chief executive on Wednesday, with the Secretary also expected to address Members of Parliament during debate on aviation legislation.
The National Air Traffic Service announced on social media that efforts would continue to support airlines and airports in recovering from Tuesday’s problems.
The organisation stated that the recovery process had proven particularly complex, creating challenges across the entire aviation network that would require time to fully resolve.
An apology was extended to affected passengers, who were advised to check directly with their airline regarding flight status.
Passengers whose journeys were disrupted may have been entitled to certain protections under UK regulations.
These included the provision of meals, refreshments, communication facilities, accommodation and transport while awaiting their destination, regardless of the delay duration or its cause.
Where airlines could not arrange assistance during significant disruption, passengers could make reasonable arrangements independently and seek reimbursement with supporting documentation.
Compensation entitlements could also apply in cases where travellers received fewer than fourteen days’ notice of cancellation.
Such payments were typically unavailable when disruption resulted from extraordinary circumstances including severe weather, industrial action at airports or air traffic control facilities, or other exceptional events.
For cancellations notified between seven and fourteen days in advance, amounts of two hundred and twenty pounds for short-haul flights, three hundred and fifty pounds for medium-haul, and five hundred and twenty pounds for long-haul routes could be payable, subject to final destination delay conditions.
For less than seven days’ notice, compensation amounts varied according to flight distance and delay length.
Affected travellers could alternatively request refunds for unused bookings or seek alternative flight arrangements.
