Aer Lingus flight cancellations: Hundreds of flights stripped from summer schedule
Irish airline Aer Lingus has cancelled hundreds of flights from its summer schedule.
Hundreds of flights have been stripped from the Aer Lingus summer schedule, it has emerged. The Irish airline has cancelled the flights “due to mandatory maintenance on aircraft”, a spokesperson has said.
Documents seen by the Irish Independent reveal “more than 500” Aer Lingus flights are being cut. The reduced schedule could mean travel disruption for thousands of passengers travelling from Dublin, Shannon and Cork airports.
An Aer Lingus spokesperson said the changes to the schedule apply to around two percent of the airline’s overall operations. The Peak season cancellations are understood to affect domestic, European and transatlantic routes.
Most passengers will be offered alternative same-day services where possible, the airline has said. The spokesperson added: “Aer Lingus has commenced operating its planned summer schedule. A number of recent cancellations have been required due to mandatory maintenance on aircraft, along with a limited number of schedule adjustments.
“Where schedule adjustments are being made, the vast majority of customers are being reaccommodated on same-day services.”
In February, Aer Lingus' parent company International Airlines Group (IAG) said its operating profit increased by 17.3% last year to a record 5.0 billion euros (£4.4 billion). That is up from 4.3 billion euros (£3.8 billion) in 2024.
The company attributed its “record financial performance” to “long-term demand growth in our core markets and constrained supply in a consolidating industry”. IAG said its available seat kilometres – a measure of its capacity – grew by 2.4% in 2025.
IAG chief executive Luis Gallego said: “We reported another year of exceptional performance in 2025, delivering for our customers with continued improvements in on-time performance and customer satisfaction.
“This sector-leading operational performance is translating into world-class financial results, with outstanding margins and superior return on capital. Execution of our strategy and transformation programme is creating value for shareholders.”
He added: “Looking ahead, demand is strong, with research and market data indicating that travellers in our core markets within Europe and across the Atlantic remain committed to flying the same or more in 2026.”
