If you are hoping to fly to or from Spain from the Irish Airports of Dublin, Shannon or Cork today you might have to change your plans due to strike action by air traffic controllers.
The action will have quite an impact as Dublin airport is the headquarters of AerLingus and Ryanair, and Shannon is an important stopover for passengers travelling to the USA.
The dispute is about overdue pay raises and 15 controllers being suspended for refusing to adopt the new work practices.
Ryanair has been forced to axe 52 flights which will affect 6000 passengers, but they are offering travellers the opportunity to re-book their tickets or claim a full refund. The routes most affected are flights from Dublin to Alicante Airport and Murcia Airport.
