EasyJet cabin staff based in Spain are planning to strike for nine days in July – just as the peak summer travel season gets under way.
They will walk out in three phases across the month – between the 1st and 3rd, between the 15th and 17th, and finally between the 29th and 31st.
They are protesting against low wages, Miguel Galan from the USO union told reporters.
The airline’s flight attendants in Spain are demanding a 40% increase to their basic salaries, Mr Galan said.
“The company underestimated the outlook, was more pessimistic and conservative and is not ready for the demand…
this generates a domino effect on us.”
Still, the union, which says it represents 80% of the 450 staff based in Spain, still hopes an agreement can be reached to
avoid the strike during a meeting with management on Tuesday.
The news from Spain comes shortly after the low-fare carrier announced plans to cut more UK flights over the busy summer period.
It is thought that up to 10,000 of 160,000 flights on sale for July, August and September may no longer go ahead.
However, chief executive Johan Lundgren said the airline had not yet decided how many cancellations there might be during those months.
The airline has blamed staff shortages in ground handling and at airports, as well as air traffic control delays for increased turnaround times, delayed flights and cancellations.
