Comfort. Not good very little space after the person in front of you lay back.

Great if not for the boarding by bus at Heathrow terminal 3. Medieval disappointing time-consuming and very hard on handicapped flyers. It was awful

Positive: It was refreshingly easy and polite check-in and boarding staff. Flight was on time and Helsinki is a very well-signposted airport. Shopping was nice as well. Flight was not full and I had lots of space in economy. Flight was perfectly on time. Negative: Food and drink not very good, but that it is normal on any airline. Didn't expect anything else.

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.

Very good seat, very comfortable, good food, and good service.

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.

All reviews good because...flight from BWI to London ,economy seats was miserable. I usually book 1,step up from economy but this would have added 1500 bucks 1 way. Bit the bullet and upgraded for retun flight, otherwise all ratings would have been rock bottom.

It was okay. The airplane was a little smaller than a flight from Thailand to Helsinki.

This was an absolutely exceptional flight. The flight attendants were extremely attentive and very friendly. They seemed to go out of their way to make us comfortable and to make sure that we had everything we needed., We were in business and were very happy with the size and the details for our pods. We would definitely recommend Finnair and will definitely be flying with them again.

Excellent business class seats, service and food. No airline does it better.

The only negative thing was boarding a Copenhagen-bound flight in Toronto. The middle aged woman at the desk gave me some bad time, claiming they wouldn't allow me to board the flight, switching to russian in the process. After I asked her to speak English and explained her that I had to reroute with the airline due to flight cancelations that where beyond my contro and will be leaving the Shengen zone promptly, she told me I had to check in my small bag because the flight was full and they needed someone to give up their cabin luggage. After I refused, she told me she would have to check my bag if it fits the allowed dimensions, which it did. I understand she's not an SAS employee, I understand she needs to check the documents and also make sure there's enough room for overhead bags on a plane. What really made me mad was her hostike tone and the beyond poor communication skills. Basic politeness would go a long way.

I could make online check-in anywhere. Check-in was complicated I could use your app for and it was hard find information for check-in for airline checking in their app. After hour I had to go anyway to make check in the airport. Rest of the flight was more than good

The connection time from the flight to Stockholm and the flight out of Stockholm was too short. Due to a knee injury, I almost missed the second flight. From deplaning at E5 to boarding at F69 takes more than 40 minutes.

The stewardess was incredibly rude. The gave you only one drink with dinner.

It wasn't an AeroMexico connect but SAS, I dunno where that AeroMexico info came from. A word to the wise - do NOT get an international connecting flight into Eurooe at Copenhagen that has less than an hour layover between flights, or you'll never make it. You'll need to go thru immigration at the airport before catching your next flight, which takes some time, and then it could be a good half hour walk or more over to your next gate. Kayak lined up flights for us with only a 45-minute layover and it was literally impossible to make the nect flight ... I figured if their robots thought it woukd work it should be ok, but don't trust the robots! Had to wait for the next plane to make it to our destination.

Really good. Everything went smoothly. That's what I hope for when I'm on a long flight, especially with multiple changes. Thank you SAS.

I wish they have given us explanations for the delays. And the rebooking process in Copenhagen was too long. I had to wait about 4 hours before they assign me a hotel. From there the handling process (accommodation, transportation and meal) was excellent.

Since our earlier flight was delayed, we missed this flight and were rerouted on Lufthansa 2 days later.

really nothing ...uncomfortable seating, cramped ....no better than a US short hopper flight.. never again
