Aer Lingus will start notifying customers today ahead of pilots’ planned industrial action.
Aer Lingus pilots will start work-to-rule action from Wednesday, meaning they will decline overtime working or any out-of-hours duties.
As a result, the airline expects to cancel up to 20% of flights.
The work to rule action could potentially impact up to 8,000 passengers a day.
It represents over 40 flights a day scrapped.
The airline operates an average of 220 flights a day during the summer season.
Donal Moriarty, chief corporate affairs officer said: “Impacted passengers will be contacted and advised of cancellations and given their options in terms of refund, re-accommodation or voucher.”
Pilots are taking action over a requested pay increase of nearly 24%.
The airline has offered just over half of this.
The pilots’ union say their demand is the equivalent of real terms inflation since they last had a pay rise in 2019.
The airline’s short-haul Europe schedule is likely to be most at risk.
