British Airways said the problem is “affecting the vast majority of our flights”.
Gatwick airport said it is affecting all outbound flights across the UK.
Birmingham airport said “departing flights from many UK airports have been suspended”.
Several flights scheduled to arrive at UK airports are being forced to conduct holding patterns or divert elsewhere.
More than 700,000 passengers suffered disruption when flights were grounded at UK airports on August 28 2023 when Nats suffered a technical glitch while processing a flight plan.
