Finnair warns of major flight disruptions due to union action

Finnair announced that industrial action by the Finnish Aviation Union at Helsinki Airport will cause extensive disruptions to its flight operations on June 4. The announcement was made on X.

According to Finnair, the Finnish Aviation Union (IAU) has declared industrial action at Helsinki Airport scheduled for June 4, resulting in significant operational challenges for the airline. The strike affects essential ground services such as baggage handling, aircraft towing, and refueling—services that Finnair depends on to maintain daily operations. Customers are advised to monitor their flight status and consider rebooking options provided by the airline.

As reported by Yle News, the industrial action is part of coordinated demonstrations against the Finnish government’s labor market reforms, involving multiple unions. The IAU’s participation directly affects airport logistics, and Helsinki Airport is expected to operate with severely limited ground crew capacity. This disruption will impact not only Finnair but also broader airport operations throughout the day.
