Ryanair has confirmed that it expects tomorrow's planned strike by up to 100 pilots based in Dublin to go ahead.
The company has cancelled 20 flights altering the travel plans of 3,500 passengers.
Meanwhile industrial unrest is ramping up across Europe.
Reps for staff in Belguim and Sweden have announced they will strike tomorrow week, while unions for German and Dutch based pilots have suggested they'll co-ordinate their action to take place on the same day.
Elsewhere the British Airline Pilots’ Association has issued a “failure to agree notice” to Ryanair.
That's the first of several steps towards strike action in their industrial relations process
