Unfortunately, the month and year doesn't go back so I can write a review on my first time flying with Finnair but will add it here as well.
April 2019 / AY0912
First time travelling with Finnair and I didn't expect much as it was my first time. But it was fairly a good trip, though some things could have been better.
PROS: easy check-in, comfy enough seats, good entertainment, good service from cabin crew, extra check-in luggage can be bought online (as long as it's Finnair is the one operating the whole trip)
CONS: Food could be better, leg-room seats are not worth if people are just going to hang around in front you. For some reason, people like to stand there and look out the small window and toilet queue can be exaggerated. When checking in on return flight, treatment was unfair for those who were "non-Korean". I could see they were not strict with Koreans when checking their hand-carriers but for us, they had to be weighed in consistency. Also, the attitude of the check-in clerks were not good!

Second time travelling and still no expectations from my side, as I already knew how travelling with Finnair was.
PROS: still easy check-in, can still buy extra luggage online (this is good when you have done too much shopping), still good service by cabin crew, good entertainment. Leg-room seats were good this time (make sure the flight from Helsinki is during the night, so after lift-off, the lights are turned off and it's sleeping time - to avoid people hanging in front of you).
CONS: food can still be better
During our return trip from Hong Kong, there was an ongoing strike in Finnair and it affected our flight. Luckily, Finnair was really fast in booking us in a new flight on the same, only a couple of hours in difference.
CONS: it was a bit messy to check-in the extra luggage we had bought online because Finnair could not transfer this data to Cathay's system. We went back and forth between Finnair and Cathay's customer desk, which could have been avoided if they just called each other and confirm the payment we had done for the extra luggage. Unfortunately, you need to pay for the extra luggage again if you have been re-booked with a different airline. None-the-less, things were fixed and check-in was easy from there.
PROS: Getting the refund back for the extra payment on the luggage, was easy. Fill out the form online and it took about 1 week before the money was transferred.
Overall, it has been good travelling with Finnair. Some minor unpleasant experiences but hopefully those can be improved.
