The seats are very uncomfortable. They never have tomato juice. Usually late

Finnair was not able to get our luggage on a connecting flight and there was a substantial delay of two days to obtain our lugguage. They did not communicate well, and we had to travel a significant distance to finally get our luggage. It has been a very negative experience.

On a more than 8 hours flight was only one meal included, which I have never experienced before. Always two meals on the overseas flight. It was very weird.

Business seating is soooo uncomfortable. You can sit straight up or lay down. You need pillows behind you because the back doesn’t lay down. Those are need to “prop” you up. The chair has no padding whatsoever. Food was gross. I’ve eaten on Finnair before and the food was exceptional. This time it gave 2 people in our party diarrhea. It was the chicken dish. I took 2 bites and didn’t eat anything more. The flight attendants were nice. You needed an additional lounge in Terminal D at DFW Airport. After waiting 40 minutes to enter, we finally gave up and went to a bar across from the club doors. I’m unsure if I’ll ever book a Finnair flight again.

It was a good flight, very comfortable seats for sleeping in business class. Probably the most comfortable business class seat I've ever had (20+ times in business class on various airlines). Service was good, but the only downside is my screen didn't work and it had to be reset multiple times to get it to shut off. I had to block my eyes because the screen was white almost the entire flight and I wore an eye mask when I slept. But when eating and reading in my seat, my eyes hurt because the only way to turn the screen off was reset it and the screen would only be off for a few minutes at a time.

Everything was wonderful! AirBus seats are more comfortable to sleep in as compared to the Boeing planes.

Great. It was awesome to have boarding from the front and back of the plane as it made the process go very quickly

We had an excellent trip with Finnair. This was our first time and we’re very pleased. The only issue was with the boarding - it was a little bit confusing and needs a little bit of streamlining.

Flight delayed over an hour. They said they would hold our connection but then did not.

The staff were all particularly great. The plane was clean and fresh. The bassinet worked great. It was all very nice.

Both of our Business Class seats were broken. I'm sure they didn't just break before we boarded but were broken prior. They would not recline. We could sit up straight or lie down, nothing that would allow us to sit back and relax on a 12 hour flight. Totally unacceptable. Very expensive and a waste or money.

It was very good excitement. We Enjoy everything except the food

I really enjoyed the food, only bad part on one of my flights my screen was a bit buggy but it wasn't a big deal it was one of their older planes so I understand that happens

No customer service. Non educated staff members with no will to support or service the passenger.

The segment bkk ist was ok. The segment ist to yul the boarding was chaotic with 5 control before get in the plain, in addition to normal control by scanner and metal detector during transfert

Very good, it took a little too long for the food to come out on a service that left after midnight but everything was great.

Business class in Turkish airlines is like none other. They separate themselves and highly recommend it

I will avoid this airline as much as possible. Service was rude, and I don’t think the crew knew how to answer a CALL LIGHT. I pushed my call light on the ohare to Istanbul and the Istanbul to Thailand flight because I was very very thirsty. NO ONE CAME. I pushed it twice! NO ONE CAME! Why have a call light when no one will come? My experience was the WORSE AND I WILL NEVER EVER FLY WITH THIS AIRLINE AGAIN. The cabin crew needs to learn MANNERS AND BE RETRAINED on their jobs on how to be helpful and kind instead of being short with their customers and ANSWER CALL LIGHTS! I honestly wouldn’t be suprised this airline goes out of business.

Flight attendants were harsh, food could be better, took way too long to pick up food trays, were stuck with the crying babies the entire to and from trip. Restrictions of 8 kg for cabin luggage is ridiculous that’s barely 2 pairs of pants, shirts, shoes. There shouldn’t be any restrictions on the carry on luggage size except the checked in luggage. Attendants don’t even help with putting luggage in cabin space. Attendant picked up food tray and spilled cherry juice all over my husband and has the nerve to come back to ask why he hadn’t changed his clothes.

Business Class Service was unacceptable. 7 flight time changes and delays
