As industrial action will cause significant disruption to flight operations, Finnair will have to cancel approximately 143 flights on Tuesday, 17 June. Flight cancellations are expected to affect approximately 6,500 Finnair customers.
Flight cancellations due to industrial action have congested Finnair's customer service, resulting in longer than usual wait times. Finnair previously allowed customers scheduled to travel on strike days to reschedule their flights, helping them avoid disruptions.
The industrial action may cause disruptions, for example, in baggage handling at Helsinki Airport on Tuesday. Customers traveling on Tuesday are encouraged to check in advance, arrive at the airport on time, and pack essential items, such as medicines, in their carry-on baggage.
The IAU has also announced similar industrial action on Thursday, 19 June 2025. Finnair is still assessing the exact effects of the industrial action on that day's traffic, but it is likely that, if it takes place, it will cause disruptions that day as well. Finnair will announce possible flight cancellations for Thursday, 19 June, on Tuesday, 17 June.
