Industrial action during the airline’s first quarter pushed up losses and led the Stockholm-based airline to revise its full-year prediction.
The deficit in February, March and April soared year-on-year from £40 million to £100.4 million following industrial action which saw 2,700 flights cancelled, affecting an estimated 270,000 passengers.
This was despite turnover during the period increasing year on year from £818.4 million to £840.8 million.
