Ryanair has been granted permission by the High Court to seek an order to prevent industrial action next week.
The application for an injunction to stop some of the airline's Irish based pilots from going on strike, will be heard on Monday morning.
Directly-employed Ryanair pilots based in Ireland, who are members of the Irish Air Line Pilots' Association (IALPA), are to strike for 48 hours from midnight on 22 August.
Earlier this week, Fórsa, the parent trade union of IALPA, served the company with notice of industrial action next Thursday and Friday, over a dispute about pay and conditions.
Around 180 of Ryanair's Irish based pilots are represented by IALPA and Fórsa,
94% of the pilots who took part in a recent ballot, voted in favour of industrial action.
Yesterday, Ryanair accused Fórsa of collapsing mediation talks aimed at resolving a number of issues between the two sides.
Counsel for Ryanair told the High Court today that the trade union had not allowed the mediation process, under Kieran Mulvey, to be completed before serving the notice of strike action and he said the planned work stoppage is in breach of an agreement reached between the parties last year.
Martin Hayden SC also told the court that the strike was designed to cause "maximum disruption" for customers.
Following a short hearing this afternoon, Ms Justice Carmel Stewart gave the airline permission to serve short notice of the injunctions proceedings against the union.
The matter will be heard in then High Court at 11am on Monday.
