The Finnish Aviation Union (IAU) will conduct a fresh round of industrial action on June 17 and 19, 2025, resulting in large-scale disruption to operations at Helsinki Airport.
This comes after a rather turbulent month for the Finnish carrier, as it was forced to cancel hundreds of flights due to industrial action by the IAU at its main hub.
According to IAU, new four-hour strikes will affect different work shifts. Finnair - the largest airline operating at Helsinki Airport – said the industrial action will impact all essential ground services related to the airline’s flights.
The airline said it expects the effects of the industrial action to be “more significant” than those of previous strikes. Finnair is expecting to operate over 600 flights across the days that strike action has been called.
“If the strike goes ahead, a majority of these flights will likely be cancelled. Also, flights on days surrounding the strikes could be affected,” the carrier said in a statement.
Finnair will start cancelling flights on the strike days two days before the departure date of the flight, once it has a “clearer picture” of the available resources
The IAU has also announced industrial action for June 11, 2025, however the airline stated that the effects on this day’s flights are minor, with Finnair aiming to operate its flights on the day as scheduled.
