Irish holidaymakers could face travel chaos as Spanish air traffic controllers call a series of partial strikes over a four day period.
The controllers will strike on June 8, 10, 12 and 14, for two hours each morning, and two hours each afternoon, across the country.
They are disputing a series of fines and suspensions, decided on by the country's airports operator, resulting from an industrial dispute in 2010.
The action comes as Spain starts its lucrative summer tourism season, which accounts for over 10pc of its economic output.
The Irish Travel Agents Association (ITAA) said that customers who are concerned about their holiday plans should contact their travel agent.
