Thousands of Aer Lingus customers are set to be impacted by industrial action being taken by pilots from next week.
Here's everything you need to know about the dispute and its consequences...
What's the dispute over?
Aer Lingus pilots, through their union – the Irish Air Line Pilots Association (Ialpa) – are seeking a pay increase of just under 24 per cent.
The association say the rate being sought is reflective of inflation since the last pay increase, which happened in 2019.
However, Aer Lingus has labelled the request "exorbitant, outrageous and untenable".
Negotiations between the two sides have so far proved fruitless, and a recommendation from the Labour Court, which heard the matter back in April, for a 9.25 per cent increase was rejected by Ialpa.
When is the industrial action taking place?
There are now two aspects to the pilots' industrial action – a work-to-rule and an eight-hour strike.
The work-to-rule, during which workers continue to fulfil their contractual obligations, but no more, was announced on Tuesday.
Pilots will carry out no overtime during the work-to-rule, which is due to commence on Wednesday, June 26th.
The second part of the action was announced by Ialpa on Friday, confirming its members in Aer Lingus will stage an all-out eight-hour strike on Saturday, June 29th.
How many flights have been impacted?
Both the work-to-rule and strike action have resulted in significant flight cancellations next week, with thousands of customers impacted.
In addition, some flights have also been rescheduled due to Saturday's strike to avoid further cancellations.
Following the announcement of the work-to-rule, Aer Lingus released a list of 124 flights which have been cancelled over the first five days of the planned action.
However, following the subsequent announcement of the eight-hour strike on June 29th, the airline cancelled 120 further flights which had been due to fly that day.
Information on the flights which have been cancelled and rescheduled can be found on the Aer Lingus website.
How many customers are affected?
Aer Lingus said the work-to-rule action will affect approximately 20,000 customers over the first five days of the action.
The subsequent cancellation prompted by the Saturday strike will impact around 15,000 short-haul customers, while some long-haul customers have had their flight times changed to avoid the strike period.
What should I do if I'm due to fly with Aer Lingus during the industrial action?
In a statement on Saturday, Aer Lingus said it is automatically rebooking some affected customers onto alternative flights.
Other passengers have been informed of the cancellations by email, and offered the option to change their flights or request a refund/voucher.
For those due to travel with Aer Lingus over the coming days, it is worth keeping an eye on the Aer Lingus website for any updates.
