Portugal's National Union of Civil Aviation Cabin Crew called the five-day walkout beginning Wednesday to protest what it alleges is Ryanair's non-compliance with Portuguese labor laws, including holiday pay and days off.
The airline switched many passengers to other flights before the strike, and the Portuguese government enacted a law forcing the cabin crew to work on a stipulated number of flights because the walkout came during the busy summer vacation period and could have caused chaos.
Ryanair pilots based in Britain plan a walkout Thursday over pay and benefits, and Spanish cabin crew are due to hold a 10-day strike in September over job cuts.
