Aer Lingus (United Kingdom) (EG, Belfast City) operated its final flight on March 31, 2026, and is in the process of transferring both of its A330-300s back to the parent company, Aer Lingus (EI, Dublin International).

EI-EDY (msn 1025) was reregistered in Ireland on March 13, 2026, following its last revenue flight under the UK certificate on March 2, on the Orlando International-Manchester route, then as G-EIDY. It has been operating for Aer Lingus under the Irish certificate since March 19.

The second unit of the type, G-EILA (msn 1106), continued under the British AOC until the end of March, with the last service from Orlando on March 30. It was ferried to Dublin International the next day and has remained parked since then. UK records indicate that the aircraft remains registered in the country, but an application to export it has already been filed.

Aer Lingus announced earlier this year that it would close its Manchester base at the end of March, ending its transatlantic services from the UK.

The IAG International Airlines Group-owned airline did not respond to ch-aviation's question whether it planned to retain the UK certificate for potential future use or surrender it.

Aer Lingus' fleet on the Irish certificate comprises twenty-seven A320-200s, eight A320-200Ns, eight A321-200NX(LR)s, six A321-200NY(XLR)s, three A330-200s, and eleven A330-300s (excluding G-EILA, which has yet to be transferred).
