Ryanair's Spanish cabin crew union USO called on its members to strike every week between August 8 and January 7 from Monday to Thursday to press demands for higher pay and better working conditions, a union spokesperson said on Wednesday.

Spanish cabin crew working for the airline walked out for several days in July, mainly on weekends, causing disruption at many Spanish airports.

Spokespeople for Ryanair in Spain were not immediately available for comment. (Reporting by Inti Landauro and Christina Thykjaer; editing by John Stonestreet)
