NATS software fault disrupts Amsterdam Schiphol and UK airports as over 1,000 flights are canceled

Disruption overview

A software fault in NATS' flight-plan processing system on 8 September 2026 briefly halted air traffic and triggered capacity restrictions across UK and Irish airspace, with disruption continuing into 9 September 2026. Amsterdam Schiphol Airport was especially affected, with 58 flights to and from UK airports already canceled and further departures delayed, while KLM, EasyJet, and British Airways all cut services as more than 1,000 flights were canceled across the wider network. Because the problem came from national air traffic control rather than the airlines themselves, compensation under EC 261 is unlikely in most cases, but passengers should still be offered rerouting, refunds, and care during long waits.

Disruption details

A technical fault in NATS' flight-plan processing system on 8 September 2026 briefly halted air traffic and triggered capacity restrictions across UK and Irish airspace, and the knock-on effects were still being felt on 9 September 2026. Amsterdam Schiphol Airport was one of the airports most affected because of its busy schedule of flights to the UK.

More than 1,000 flights were canceled during the height of the disruption across the wider UK-Ireland network. At Schiphol alone, 58 flights between Amsterdam and UK airports had already been canceled, and additional departures were running late, leaving many passengers to deal with sudden itinerary changes, longer waits, and busy rebooking desks.

For many travelers, this meant uncertainty long after the original fault had been fixed. A technical problem in air traffic control can spread quickly from one airport to another, especially when aircraft, crews, and connecting passengers are all moving through tightly timed schedules.

The disruption reached several major airlines. KLM was unable to operate any services to or from England while the fault persisted. EasyJet canceled about 200 flights across its domestic and European network, while British Airways canceled about 100, showing how heavily UK-linked networks were exposed.

Within the UK, London Heathrow Airport, London Gatwick Airport, Manchester Airport, and Birmingham Airport were among the main hubs operating with reduced capacity. Even after the software problem was remedied later on 8 September 2026, airlines and airports still had to work through aircraft backlogs and crew displacement, so normal schedules could not restart straight away.

For passengers, that meant the disruption continued well beyond the moment the system came back online. Airlines still needed time to reposition planes and crews, and airport operators on both sides of the North Sea expected irregular operations to continue for at least the rest of 9 September 2026.

The highest-impact sector remained flights between Amsterdam and the UK. Services from Schiphol to non-UK destinations were largely operating normally, but routes linked to England were much more exposed to delays and cancellations. That uneven recovery mattered if you were connecting through Amsterdam or trying to rebook onto another service.

If you're flying during the recovery period, a few practical steps can help:

• Check your flight status before leaving for the airport.

• Allow extra time for rebooking queues and customer service lines.

• Follow updates from your airline and airport in case departure times or gates change.

This kind of disruption is usually treated as outside the airline's control because it was triggered by a technical failure at the national air traffic control provider, not by an operational issue within the airline itself. That means compensation under EC 261 is unlikely for most affected passengers, even if the delay or cancellation was significant.

Still, you're not without support. If your flight was canceled or heavily delayed, your airline should still help with rerouting or a refund, food and refreshments during long waits, and hotel accommodation with transport if you were stranded overnight.
