• Nearly 300 flights cancelled across major UK airports.
• Technical issue linked to the air traffic control provider NATS.
• Airlines advise passengers to check flight statuses due to ongoing disruptions.

On September 8, technical problems in the air traffic control system caused significant disruptions at several major UK airports, including Heathrow, Gatwick, and Manchester. Nearly 300 flights were cancelled, and hundreds more were delayed as the National Air Traffic Services (NATS) addressed the issue in its flight processing system. While the airspace remains open, NATS indicated recovery from the incident would take time, according to Reuters and India Times.

Airports such as Edinburgh and Dublin also experienced impacts due to the disruptions, with Edinburgh warning that its operations might be affected. According to NATS, “Flights are still departing and airspace is open, but recovery will take some time.” Advancing through the day, Heathrow and Gatwick continued to face pausing and resuming departures, leading to a cautionary message for passengers to contact their airlines for updates, as reported by BBC and Reuters.

The extent of the disruptions prompted multiple airlines, including British Airways and Ryanair, to inform travelers that the situation was out of their control and to stay in contact for further information. Data reported by FlightAware revealed that Heathrow had cancelled around 100 flights while approximately 250 flights at Gatwick were delayed, influencing a significant part of operations at these airports, according to India Times.

NATS had faced prior scrutiny regarding its contingency plans after a similar system failure in the past had resulted in chaos across British airports, leading to £100 million in costs for airlines in refunds and compensation as indicated by Reuters and India Times.
