NATS technical fault at Prestwick disrupts flights across northern UK
Published · Updated
What happened
NATS reported that a technical issue at its Prestwick centre on 21 September 2026 required traffic regulations that disrupted flights across parts of Scotland, Northern Ireland and northern England. NATS later said the fault had been fixed.
Why it matters
Air traffic restrictions at a UK control centre can delay passenger flights, cargo movements, crew rotations and airport operations within hours. A repeat systems failure also raises scrutiny of operational resilience, fallback arrangements and the cost exposure for airlines and transport operators.
National Air Traffic Services said on 21 September 2026 that a technical issue at its Prestwick centre led it to impose traffic regulations affecting airspace over parts of Scotland, Northern Ireland and northern England before the fault was fixed. The disruption affected airlines, airports and passengers on a live operating day rather than as a forecast risk. For UK ministers and business leaders, the incident revives questions about redundancy, incident response and public confidence in transport infrastructure after another air traffic control failure.
