Aer Lingus will end operations on its UK air operator certificate on 31 March 2026, transferring its two A330-300s from Belfast City back to Dublin. In parallel, the airline has cancelled several Summer 2026 flights—citing required maintenance and operational challenges—including disruption expected across UK and Europe, with IALPA pointing to pilot shortages rather than fuel costs. Ireland is also seeking SAF tax relief after Aer Lingus cancelled 500 flights amid rising fuel pressure.
