HELSINKI- Industrial action by the Finnish Aviation Union is set to disrupt operations at Finnair (AY), leading to the cancellation of approximately 110 flights on 4 June 2025. The disruptions will affect thousands of travelers at Helsinki Airport (HEL), Finnair’s primary hub.
The airline expects service interruptions throughout the day, especially in ground handling and catering. Affected passengers will be rebooked on alternative flights or offered full refunds for unused tickets.
Finnair Cancels 110 Flights Amid Strike
Finnair has confirmed that the industrial action at Helsinki Airport (HEL) on 4 June 2025, led by the Finnish Aviation Union (IAU), will significantly affect its operations.
The action targets key support functions—ground handling and catering—across various work shifts, making it difficult for the airline to maintain regular flight schedules.
Approximately 110 flights have been canceled, impacting around 11,000 passengers. The cancellations are part of Finnair’s effort to manage safety and service quality during the strike.
The airline began offering rescheduling options in advance, and many customers have already adjusted their travel plans.
Affected passengers will be notified directly once their flight is canceled. Rebooking options will appear automatically in the airline’s Manage Booking portal and mobile app.
Customers can choose the proposed rerouting, modify the route within availability, or request a full refund for any unused tickets.
