A technical issue at an air traffic control center in Prestwick, Scotland, led to cancellations and delays for UK flights on Monday morning. National Air Traffic Services (NATS) reported disruptions mainly affecting flights between London and cities in northern England and Scotland. Ryanair estimated over 25,000 passengers would be impacted, while EasyJet criticized NATS' system resilience following a similar incident two weeks prior.

Story summary
On Monday, Nats, Britain's air traffic control provider, faced renewed criticism after a "connectivity issue" at its Prestwick center in Scotland caused delays and disruptions to flights across Scotland and northern England. This incident is the second major disruption within two weeks, following a software fault on September 8 that canceled over 2,000 flights and affected hundreds of thousands of passengers.
Ryanair estimated that more than 25,000 of its passengers were impacted by Monday's delays, with around 140 flights delayed. The company's chief operations officer, Neal McMahon, called for the resignation of Nats CEO Martin Rolfe, accusing him of presiding over repeated system failures and passenger disruption.
EasyJet also criticized the resilience of Nats' systems, stating that the latest incident "calls into question" their reliability. Meanwhile, Airlines UK CEO Tim Alderslade emphasized the need for ATC infrastructure to be resilient enough to keep people moving, calling the recent failure a significant issue affecting both passengers and airlines.
Despite growing calls for Rolfe's resignation, Prime Minister Rishi Sunak did not publicly back Rolfe but stated that it was initially up to the Transport Secretary to investigate the cause of these recurring issues.
