Aer Lingus has announced it has cancelled a number of flights to European destinations due to poor demand from customers.
The routes have been cancelled for the remainder of 2021.
The company has not given exact details of the destinations affected, but said all customers that had booked have been contacted and offered a refund.
The airlines said additional capacity will now be added to routes where demand is greatest.
It said it plans to fly as full a schedule as possible after 19 July, but it was not possible to accurately predict where the demand would be.
