Passengers are facing delays this Monday morning, 21 September 2026, following further air traffic control issues affecting several airports across the UK. National Air Traffic Services (Nats) is investigating a technical issue at its Prestwick centre in Scotland.
Airlines have advised customers to anticipate disruption. To ensure safety, air traffic regulations have been implemented to manage demand. Engineers are currently on site working to resolve the problem.
Airports reportedly affected by this issue include Manchester Airport, Belfast City Airport, Belfast International Airport, Glasgow Airport, and Aberdeen Airport. Nats has stated that this current issue is unrelated to the technical problems experienced earlier this month.
