I just cancelled my trip 26 feb to 1 march HEL - HKG and back
Very helpfull customer service I must say.
I did not want to rebook for a flight within the 3 months window they gave as I believe the virus will not be over by may (this is only me thinking)
I never flew Finnair Biz class so I was so much looking forward, but I am sure there will be more opportunities.
