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

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

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.

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

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.

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.

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

Wish that everyone would board the back of the plane first. Also let kids on first. The gate wasn’t open at arrival and we waited 45 minutes to takeoff. They made up for time in the air.

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.

They lost my luggage and can’t find it. My trip is ruined. Online tracking of lost luggage doesn’t work

No free Wi-Fi. I have SkyMiles but not a high status, having an account has been enough for Wi-Fi on other flights, but this one was going to charge me to use it. Also turbulence was really bad toward the end, but I didn't count this in my ratings since I know Delta cannot control the weather - it's 2026 and lack of WiFi alone is enough for a poor rating.

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

Cancelled flight, wasn't refunded paid selected seats. Poor customer service. Called airline and they didn't realize the flight was cancelled until several hours after the email notice was sent.

The worst with the trip was the space in economy, my knees are still hurting. There was no way to control personal air by turning a knob above you, it was way to hot on both rides. During the night flight they allowed 2 people from across the aile which was narrow to sit and talk for 7 hours while also using tablets and the flashlight from their phones pointing into the row where I sat at times. They allowed people with way too large baggage to bring onboard. I paid way too much for the ticket ($1,364} for economy. Kayak misinformed me to get cancellation insurance that was only valid for a very short time (less than 12 hours) and was over one hundred dollars. Hotel booking was incorrect, I had the room booked myself at the hotel, only double or larger rooms available which I paid over 400 dollars for. I will never fly with SAS again unless there is no other alternative.

Crew members were excellent. The seat wasn’t the best as well as a food options.

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.

5 of my 7 pieces of luggage are missing and they cant call to find out where it is. I have to fill out a form and wait for them to mail it to me in several days (if they find it). That does not work for my travel itinerary. I need my full ticket cost refunded please.

Fantastic. The only thing - out of my six luggage one was lost in Copenhagen, however it was delivered Home 3 Days later so all great..

The crew was friendly, the flight was pleasant. Thank you for your service!

Boarding process was chaotic. Confusion over Boarding gates: gate 55 or gate 56 ???. Unnecessary standing in long lines to board. Better to call out Boarding groups one at a time and everyone else to sit. Airline only has 2 Boarding groups 1-3 and 4-9. That causes over crowding and chaos

Lady next to me was coughing profusely the entire flight, other lady moved seats because of it, 8 hours of that during an overnight flight is a bit much.

The flight was ok. The seats are so small. The free wifi for members was not an option on this flight. The one flight attendant, older woman with straight white/grey hair, was very rude. The gentleman next to me asked about the wifi since he was a member as well. He stated, accurately, that the option to enter the idea number was not available. Her response was, "I don't know what to tell you" and walked away from him. The rest of the staff was wonderful. I asked another flight attendant about the wifi, she said the free wifi was not enabled on that flight (true or not- at least she was friendly). It was also pretty dirty. When I opened the tray table it had mushed crumbs and there was a dirty used pair of ear buds in my seat pocket. Lastly the air vent above my head was working but stuck so I was unable to move it to face me when it got warm. I fly American often but this really was not a great flight.

My luggage was lost at the airport but American Airlines contacted me and got it to me the next day.

24 hour delays aren’t even heard in 3rd world countries with archaic transportation systems. I’m never flying American Airlines again.

3.5 hr delay leaving Pittsburgh, notifications for which were incomplete and untimely. Connecting flight was automatically switched to one requiring more than a 30 hour layover! After waiting in a long queue, customer service reduced layover to 11 hours and also set up an earlier standby. The standby had empty seats, but the gate agent couldn't change our tickets! On top of all that my luggage was lost and has yet to even be located, much less returned 5 (FIVE!) days later. Too bad there's no rating below poor.

Canceled flight late London to Florence. Help at airport very poor. Treated poorly. Had to sleep in the airport. Lost bags- still do not have them. Horrible. I should be reimbursed!

The seats are extra cramped if you are taller than 5’8! Spring for the extra legroom seats for sure if you have a long flight!

Very disappointed with British Airways. It has been over 24 hours and I still have not received my checked baggage or any proper update. Customer support has been unresponsive, making the situation even more frustrating. Poor baggage handling and lack of communication seriously impacted my travel experience.

All the above categories was great. Seats entirely too cramped.
