Thousands of holidaymakers at Heathrow and Gatwick airports are facing significant delays and cancellations to their flights. The disruption stems from a technical issue affecting National Air Traffic Services' (NATS) flight processing system. Passengers have been left stranded as flights were grounded at London's two busiest airports, with knock-on effects reported at airports across the UK.

NATS confirmed the problem lies with its 'flight processing system' and stated that teams are working to resolve the issue. While flights are still departing and airspace remains open, the organisation warned that recovery would take time. Scores of flights have already been delayed and cancelled from both Gatwick and Heathrow, with disruptions anticipated to persist until at least 9pm.
