Air travel disruption continues at UK airports after an air traffic control system issue linked to NATS leads to widespread cancellations. Reports say 177 flights scheduled for Wednesday are cancelled, following much larger knock-on effects from the previous day.

Multiple outlets describe Tuesday as the initial disruption point, when a NATS system failure contributes to around 1,300 flight cancellations affecting travel to and from the UK, including routes involving Ireland. By Wednesday, the scale of cancellations is reported as smaller but ongoing, with 177 additional flights cancelled.

The outlets broadly align on the cause and timeline: an air traffic control systems glitch, initial cancellations on Tuesday, and continued disruption into Wednesday. Their reporting emphasis differs slightly—some focus on the number of cancellations on Wednesday, while others stress the earlier day’s wider impact—but all attribute the disruption to the NATS-related technical issue and present similar figures for both days.
