At least 244 Aer Lingus flights are now cancelled next week due to pilots’ industrial action, the airline has confirmed.

Earlier this week the Irish Airline Pilots Association (IALPA) served notice of an indefinite work-to-rule from Wednesday 26 June as part of an ongoing pay dispute.

On Friday IALPA members at Aer Lingus said they now plan to strike on Saturday 29 June from 05:00-13:00 BST.

Aer Lingus said 120 flights have been cancelled on 29 June due to the strike action, impacting 15,000 passengers.

Irish broadcaster RTÉ reported that the number of cancelled flights could increase under the pilots’ indefinite work-to-rule.

Overall, the industrial action will affect more than 40,000 passengers due to fly with the airline from 26 June and 2 July.

Aer Lingus said the cancellations would enable it to “protect as many services as possible for as many of our customers as possible”.

However, regional services to and from Belfast and Great Britain during this period “will not be affected by any industrial relations action and will operate as scheduled,” the airline said.

On Friday, Aer Lingus said in a statement that it is “appalled that IALPA would further escalate this industrial action, following the insidious action previously announced.”

It said the strike is “clearly designed to inflict maximum damage on passengers’ travel plans”.

Aer Lingus said it will work to minimise disruption to passengers.

On Thursday the airline announced that it would have to cancel between 10% and 20% of flights over the first five days of the action.
