Core Event
On September 8, 2026, a technical fault in the flight-processing system of National Air Traffic Services (NATS) triggered stop-start disruptions to departing flights at a large number of UK airports. Departures were paused at Heathrow around lunchtime, briefly resumed, and then faced further delays in the afternoon. Arrivals continued to land normally.
Background & Context
NATS provides air-traffic control services to 15 UK airports. The provider has previously experienced major outages, notably a radar-related failure in July 2023 and a “technical glitch” in August 2023 that grounded flights and affected roughly 700,000 passengers. Those incidents highlighted resilience concerns for the national air-traffic infrastructure.
Airports Affected
The fault impacted departures at the country’s busiest hubs and regional facilities, including:
- Heathrow, Gatwick, Stansted, London City, East Midlands, Manchester, Birmingham, Bristol, Aberdeen, Edinburgh, Belfast City, and several others in England, Scotland, and Northern Ireland.
Airlines such as British Airways, easyJet, Ryanair and others reported cancellations or delays, and passengers were repeatedly urged to check with their carriers.
