UK Air Traffic Control (NATS) Issue ‐ 09 September 2026

We continue to manage the impact of the technical issue that affected UK air traffic control (NATS) systems on 8 September 2026, which caused disruption to a number of Aer Lingus flights across the UK and Europe.

While the technical issue is now resolved, some Aer Lingus flights to and from UK airports, as well as a number of European services, continue to be affected.

Our teams are doing everything possible to minimise disruption and are contacting affected customers directly with the latest information on their travel options.

We sincerely thank our customers for their patience and understanding as we recover from this issue, which was outside of Aer Lingus' control.
