A network fault at NATS’ Prestwick centre disrupted flights across parts of the United Kingdom on Monday. The operator says the fault is fixed, but passengers still face delays and cancellations.

Britain’s air traffic control provider said it restricted traffic after a technical problem at its Scottish centre early on September 21. In its public statement, NATS described a connectivity fault affecting part of the network supporting its Scotland operation.
The operator said engineers had resolved the issue and staff were working with airports and airlines to lift the remaining restrictions safely. It advised passengers to obtain the latest flight information directly from their airline.
Restoring the control system does not mean every affected flight immediately returns to schedule. The Associated Press reported disruption across Scotland, Northern Ireland and northern England, with consequences expected to continue after the technical repair. Manchester, Belfast International, Edinburgh and George Best Belfast City were among the airports experiencing the most disruption, according to aviation data provider Cirium, cited by AP.
A separate failure from the earlier outage
NATS said Monday’s connectivity problem was unrelated to the incident earlier this month. Reuters reported that the earlier software failure caused about 2,000 flight cancellations. The distinction matters: Monday’s disruption should not be described as a recurrence of the same confirmed defect.
Reuters also reported cancellations by easyJet and warnings of disruption from British Airways. Those airline responses underscore the practical difference between fixing infrastructure and recovering a disrupted timetable.
What passengers can check now
The clearest immediate step is to check the operating airline’s flight-status information before travelling to the airport. An announcement that the NATS fault is fixed is not confirmation that an individual departure is operating normally.
The next operational milestone is the removal of the remaining traffic restrictions and recovery of airline schedules. NATS’ statement did not provide a universal time at which every affected service would return to normal.
