Aer Lingus has cancelled another 80 flights next week as a result of an ongoing work-to-rule by pilots.
The services affected are from Thursday July 11th to Sunday July 14th.
The majority of cancelled flights are from Dublin with a number from Cork - as well as a transatlantic service each day.
It comes as both the airline and the Irish Air Line Pilots' Association (IALPA) wait for a Labour Court recommendation to resolve the pay row.
Since pilots began their work-to-rule last Wednesday in a dispute over pay, 548 flights have been cancelled by Aer Lingus up to Sunday July 14th.
That also includes flights impacted by an eight-hour stoppage last Saturday.
The Labour Court is considering a recommendation in a bid to resolve the pay row with pilots looking for a 24% increase.
In a statement Aer Lingus criticised IALPA's "highly disruptive" industrial action.
"Implementing these cancellations is to enable us to protect as many services as possible for as many of our customers as possible," it said.
"These cancellations will be implemented today, and details will be communicated to impacted customers.
"Aer Lingus fully understands the anxiety being experienced by customers given the uncertainty caused by IALPA's industrial action and is giving impacted customers as many options as possible," the carrier added.
Customers impacted will be given the option to change their flights for free. They will also be able to claim a refund or voucher.
