Hundreds of UK flights delayed, cancelled due to Heathrow Airport air traffic control technical issue
NATS, the provider of air traffic control services at Heathrow, first reported the problem around 9 a.m. ET and resolved the issue hours later.
Flights at London's Heathrow Airport faced significant disruptions on Tuesday due to an air traffic control technical issue. The problem at the air traffic service provider, NATS, caused delays and cancellations of hundreds of flights entering and leaving Heathrow. The situation affected not just UK flights, but also resulted in cancellations at Toronto Pearson International Airport for some passengers traveling from and to Heathrow.
The issue was first flagged around 9 a.m. ET, with NATS stating on X that they were investigating a technical problem causing flight disruptions. By the afternoon, NATS confirmed that both arriving and departing flights were impacted, urging travelers to verify their flights with airlines before heading to the airport. Heathrow Airport and NATS apologized for the inconvenience caused by the prolonged technical glitch, which was eventually resolved around 2:30 p.m. ET.
The air traffic control service acknowledged the extended resolution time but assured ongoing efforts to clear the flight backlog.
