Finnair on Sunday said it was cancelling some 100 flights departing from Helsinki Airport on Sunday 20 November and Monday 21 November following a cabin crew walkout.
The Finnish Transport Workers' Union AKT has announced a cabin crew strike starting on Sunday at 3pm and ending 24 hours later on Monday.
"Flight cancellations and rerouting of customers began on Saturday and work continues today," Finnair said in a statement on Sunday, adding that it was doing "its best to offer customers a new routing to their destination."
Passengers can check the status of their flight on Finnair's website, the company said. Finnair's list of cancelled flights is here (siirryt toiseen palveluun).
Marianne Arteva of the Finnish Cabin Crew Association (SLSY) told Yle that a few hundred cabin crew staff were walking off the job.
The association said the strike was in response to Finnair's personnel policies. These include plans to subcontract inflight service staff on its Thailand and US routes in a cost-saving effort—a move that could result in Finnair shedding 450 cabin crew jobs.
"It is sad that the labour union has chosen the path of an illegal strike instead of negotiations. Throughout the autumn we have discussed savings possibilities with the unions, but unfortunately, we have not been able to achieve a result with cabin crew. We still hope to find solutions together," Jaakko Schildt, Finnair's Chief Operating Officer, said in a company release.
Finnair said its traffic will return to normal on Monday afternoon, though the strike may still impact individual flights after Monday.
