Unions and management at Ryanair are set to meet today in an effort to break the deadlock over tomorrow's planned pilot strike.
The two sides will have talks at Dublin Airport around lunchtime.
However, Thursday's strike action by up to 100 pilots based in Dublin is set to go ahead.
The airline claims only flights to the UK will be affected and says passengers that have not been of informed of cancellations can assume their flight will go ahead.
Kenny Jacobs, the spokesperson for Ryanair, said: "What we've done is cancel flights on high-frequency routes to London and UK regional airports where we have got a lot of flights where customers can easily transfer to another flight."
