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.

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.

Crew very lovely. Arrived an hour late due to bad weather. We were given new tickets to an other flight but it could have been organised better, so we did not have to run through the whole airport to.

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.

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

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.

Easy checkin. Things went off without a hitch. The the movie selection for the flight wasn’t great, though.

Beautifully maintained airplane, good food, professional crew, top-notch communication. I highly recommend Lufthansa for intercontinental flights between the United States and Europe.

The booking I made 2 months in advance got changed the week before with another flight and had to pay more for seats and luggage. Not to mention hours and hours on hold to make sure my flight is still booked.

The plane was over an hour late taking off... the plane was rather tired looking, seat cushion was thin and uncomfortable, the sound on my entertainment system wasn't working... crew are not friendly.

We boarded the plane and waited for 30 minutes ultimately for them to cancel the flight due to engineering issues.

Love the little chocolate bars, and consumer rights in EU regarding stepped refunds when flights are delayed.

Very good. I thought the choice of Mediterranean food such as falafel for lunch was very thoughtful considering we were flying to Cairo.

My flight from Krakow was delayed over 2hrs. Since i had connecting flight i was worrying that I will not be able to catch flight from Frankfurt to New York. NO information NO help, no one was able to help and let us know if passengers will be able to catch the next flight. Had to run through entire airport and (2) passports control hoping that maybe still be able to board the plane. When i got to the gate i was informed that plane was waiting for passengers that came from delayed planes. Flight departure an hr late. So i run throu airport almost having a heart attach just to fin out that they knew and they were waiting for us. I was just 5 minutes later after "official" boarding ended and they were still letting passengers in, and flight departure an hr. later.

Good but entertainment system was not easy and very buggy

We were delayed so long that I missed the next flight. I should’ve arrived in Catania at 4 o’clock and arrived at 1 AM. The late departure was due to a water leak due to a dirty filter, according to the flight staff, and that seems like something that should’ve been taken care of before the flight. It’s too simple of a mechanical problem to make you miss the whole day.
