Ryanair has accepted new pay proposals for its directly-employed pilots based in Ireland, which would see a four-year deal running to 2024. 

But it is unclear whether the Irish pilots' union Fórsa will accept the proposed Collective Labour Agreement if Ryanair presses ahead with its lawsuit against the union for €13.7m in damages. 

Ryanair claims it suffered those losses after the union threatened strike action last summer. 

At the time, Ryanair secured an injunction to halt the actual strike, but argues that the threat of disruption led to financial loss.  

That action against Fórsa and certain pilots is due back in the Commercial Court in Dublin on Friday. 

The proposals brokered by independent mediator Kieran Mulvey would see a new incremental pay scale, a change in the proportion of fixed and variable days and a continuation of a five day on, four day off roster.  

"Ryanair today confirmed that it had accepted before Christmas the recommendations of independent mediator Mr Kieran Mulvey on a four year Collective Labour Agreement (CLA) with the pilot union Forsa, to cover all Ryanair's directly employed pilots in Ireland to 2024," the airline said in a statement. 

"Ryanair will now implement the terms of this CLA, which will deliver a new pay structure along with a fixed 5/4 roster for the next four years," it said.

Ryanair employs around 5,500 pilots across its extensive network, with its Irish-based pilots accounting for fewer than 10% of them.  

However, they have been involved in numerous incidents of actual and threatened strike action over the last two-and-a-half years. 

In a statement, Fórsa said it is continuing to advise its Ryanair pilots' representatives, who are giving consideration to Mr Mulvey's recommendations.
