Easyjet's cabin crews based in Spain will go on strike this month to demand higher wages, just as the summer season gets underway.

For three days beginning on June 25, the airline's staff will strike to bring their working conditions and salaries in line with those of their colleagues in other European bases, the Spain's Worker's Union, USO, said on Tuesday.

In its statement, the union said 657 flight attendants who are based in Alicante, Barcelona, Malaga and Palma de Mallorca, could be involved in the action.

EasyJet cabin crews earn much less in Spain than in other countries, according to the union.

The airline intends to operate normally during those days, a spokesperson said, adding the company would do everything possible to minimise the impact.
