Several airports in southern England, including Heathrow and Gatwick, experienced disruptions due to a technical problem with air traffic control provider Nats. Departures were initially paused at Heathrow, leading to intermittent delays throughout the afternoon, while incoming flights continued to operate normally.
Travelers should stay updated on flight statuses and potential delays as Nats works to resolve the air traffic control issue. Monitor airline communications and consider alternative travel plans if necessary, especially for flights departing from affected airports.
