Finnair flights could be paralysed by a strike which threatens to cause disruption from tomorrow (Friday).

Last-ditch talks are still ongoing and the airline is hoping to reach an agreement and avoid the strike.

But the carrier has already had to cancel many flights to avoid congestion at Helsinki airport in the event of a strike.

The Finnish Flight Attendants’ Association (SLSY) and The Finnish Aviation Union (IAU) both plan industrial action until November 23.

“The planned industrial action would take place during the period November 15 to November 23,” Finnair said. “The strikes scheduled for alternate days would paralyse Finnair’s traffic almost completely.”

The unions have also issued an additional warning of industrial action for the period of November 27-30.

Finnair said it was “currently analysing the situation regarding these days”.

The airline urged passengers with cancelled flights not to travel to the airport and follow instructions being regularly updated on the Finnair website at finnair.fi/en/info
