The VC union, which was responsible for Ryanair's first ever pilot strike a year ago, said the two sides planned to sign a full collective labour agreement (CLA) by next March and no industrial action would be taken before then.

Ryanair, which has faced a series of strikes across Europe this year, has made significant progress in union talks in recent weeks and has said it hopes to come to agreements with unions in all its main markets before the end of March.

Europe's largest budget airline agreed a deal with a cabin crew union in Germany last month.

All pilots based in Germany will be subject to contracts under German rather than Irish law, VC said in a statement.

Germany was the last major market where Ryanair did not have an agreement with pilots.

"While it is not a full CLA (collective labour agreement) yet, this is clear progress by Ryanair and the VC union, which has been one of the more troublesome unions to date," Goodbody airlines analyst Mark Simpson said in a note.

Ryanair shares were up 0.5 percent at 11.73 euros at 0930 GMT but have lost more than a fifth of their value over the year.
