Airlines have criticised the UK’s air traffic control system after a second technical problem in two weeks caused major disruption to UK flights
EasyJet said Monday’s incident “once again calls into question the resilience” of how the service works, while Wizz Air said there was a “national confidence crisis” in National Air Traffic Services (Nats), which runs the UK’s air traffic.
The technical problem at Prestwick caused disruption at airports across Scotland, Northern Ireland and northern England, with around 150 flights cancelled.
Nats said a “connectivity issue” was to blame for the disruption, and that it had “nothing to do” with a separate software defect at Swanwick that led to the cancellation of 2,000 flights earlier in September.
The underlying issue causing Monday’s disruption has since been resolved, with Nats saying it was running at “full capacity” although officials warned of knock-on effects.
A spokesperson said they were now “focused on working with our customers to recover their residual delays and help get their operations back to normal”.
Easyjet was the worst affected airline, with 47 of its 670 scheduled departures cancelled, while British Airways has seen 12 cancellations from its 513 scheduled departures.
The UK Civil Aviation Authority (CAA) said passengers who had flights disrupted were “unlikely” to be entitled to compensation.
It said the technical issue is “likely to be considered the result of ‘extraordinary circumstances’ under passenger rights rules”, meaning that “although passengers should be looked after by airlines, they are unlikely to be entitled to compensation for delays or cancellations that were directly caused by the incident”.
An independent review by the CAA into the resilience of the UK’s air traffic control system is under way and the results will be published “within six months”, it said.
