RYANAIR cabin crew and pilots are to go on strike in five countries across Europe this month.
Earlier this week pilots voted overwhelmingly for 24-hour strike action, beginning at 1am next Thursday, July 12.
Staff claim conditions have not improved sufficiently since Ryanair recognised unions in December.
Although only pilots in the Republic voted to strike, it will lead to widespread disruption to the plans of thousands of holidaymakers, including many from the north travelling through Dublin.
Ryanair has urged unions to call off the strike - describing it as unnecessary - but the Irish Airline Pilots' Association has said the disruption will only be avoided if agreement is reached on key demands.
The airline has said it will notify affected customers of possible disruption by Tuesday, just two days before the planned strike.
Meanwhile, there will be a 24-hour walkout by cabin crew in Italy - Ryanair's second largest market - on Wednesday July 25.
Cabin crew in Portugal, Spain and Belgium will strike for two days on July 25 and 26.
