Hundreds of flights from airports across the United Kingdom are experiencing disruption due to problems with air traffic control. Airports affected include Heathrow, Gatwick, Manchester, and Stansted. British media reported the issues Tuesday evening, attributing them to technical difficulties with NATS, the air traffic control operator. Passengers are facing cancelled flights and significant delays as a result of the technical problems. NATS reported that the situation began to slowly improve after 6:00 PM Central European Time. The disruptions are causing widespread travel chaos for those departing from British airports. Further updates are expected as NATS works to fully resolve the technical issues.
