Aer Lingus has cancelled a number of flights to European destinations ahead of EU travel reopening in the coming weeks.
The airline has said that lack of demand was behind the decision with flights to places in Italy and France among those pulled from the schedule.
The company has offered refunds to those hit by the change.
An airline spokesperson said: "Aer Lingus plans to fly as full a schedule as possible, driven by demand, following the easing of travel restrictions on 19 July. Given the situation with international travel prior to the recent Government announcement, it was not possible for Aer Lingus to accurately predict where the demand would be.
"Destinations that were not attracting enough demand from customers have now been cancelled for the remainder of 2021. This will allow Aer Lingus to focus its capacity on routes where there is the greatest demand.
"Aer Lingus sought to provide customers with as much notice of cancellations as possible and in every instance a full refund has been offered to those impacted. Aer Lingus regrets any inconvenience caused."
