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

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

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.

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.

Major problems checking in at Alaska counter. They could not find our booking code because it came from Finnair.

Do not use KAYAK or Finair for future travel. Unless you purchase the tickets directly from the airline, you were going to have a difficult time checking in. Kayak canceled my flights twice and ended up causing great difficulty in me getting back from Europe because they double sold my tickets between American Airlines and Finair. The event caused significant delays and led to me having to rebook my flights.

Boarding uncomfortable. Stewardess said I would have to check my carry on as there was no room in the overhead bins. Another passenger helped me find a spot.

The boarding process seem to take longer than necessary, resulting in a 20+ minute delay

It was too cold in the plane my feet froze

Seat was hard and uncomfortable and the temperature too warm and uncomfortable.

No meals included on this long international flight. Most airlines will offer you a meal when flying internationally. Not Icelandair. Your included choices are water and coffee. Poor customer service. The airport was also very confusing.

It was good. The air plane is clean and staff were friendly.

Worst airline I’ve ever flown. Delayed 5.5 hrs, missed connecting flight, and missed an entire day of vacation. Zero customer service

The crew was wonderful at check in, the gate and on board. Felt the luggage had more room than the passengers. The seats were smaller than most domestic U.S. airlines. I'm only 5'2" and I had little legroom. There were only 2 bathrooms in coach. Needed more. The flight was very smooth but not the most comfortable.

The plane was very small and the aisle was so narrow that every time someone walked by they rubbed against me, so it was very uncomfortable.

Everything was good. Only issue comes from being vegan and flying. The food options are super limited.

Overall good for an economy fare. IMO the movie selection could be improved. Great that you can now connect bluetooth headphones to the entertainment system.

Airlines have to stop assuming passengers bring entertainment. Provide it like you used to in business class and above!! N

Great flight. One unique individual assisting in business class who should have not been there. Need more generic meals, not British centric.

There might be more food options for people who can't eat so much starch/sugar/bread/rice. Meat, cheese, walnuts/pecans for snack, maybe jerky or other kinds of meat-based snacks would be better than bread and rice and sweets. I had an extra chardonnay, which was fine. The entertainment was great.

Unfortunately, my flight was cancelled because of some sort of emergency over the Atlantic and had to return to London. While I think British Airways made every effort to mitigate the situation, I must say it was still pretty unpleasant. I do appreciate the fact, however, that British Airways put my safety first…and I think the effort to correct a bad situation was very sincere. But I think the process might be handled better in future.

Crew service was poor and very little difference between premium economy and economy. Disappointed.

My bags never made it on the flight and I now have to wait for them to arrive hopefully tomorrow. You can’t even track your bags in the app to see where they are since they didn’t arrive. You have to file a claim and then wait for them to inform you when you will receive your bag. We were already delayed for an hour due to baggage so I don’t understand how my bag didn’t make the flight.

One of the worst experience given the middle seat even asked for the change no one honored,boarded at the end and overall one of the worst experience

No WiFi working on either flight. No leg room at all, the seat in front of me left dents in my knees. If I put the tray down, it was so low it was propped up by my knees. (I’m only 182.9 cm) I’m usually cool on planes, but the planes were both hot during taxi and take-off.

It was good although our flight to the UK was cancelled and rescheduled for two days later. This was after we were already seated on the plane. We missed the first leg of our trip. BA did put us up at a hotel and paid for our meals but we lost our hotel costs in Glasgow.

The crew was very nice and pleasant. We were very reluctant to book our flight with British Airlines because we had bad experience with their flight attendants on the previous trips, they were rude and not helpful.
