American Airlines told me that I have 3 other flights in which I did not book! They told me to check with you kayak - cheap flights, my travel agent. Upon calling the person told me “ not to worry “ about these flights in my name?!?!? I never booked any of these other flights. I will not ever use this site again because of putting flights in my name that I didn’t book.

Business class should have free wi-fi. Food was horrible

Will never fly American Airlines business class again. Medicore service and very old aircraft.

Staff went above and beyond with their care for us. Flight attendants were very attentive to our needs. Food seemed too rich and too salty. Flight was fine, even with turbulence at points.

It all went very smoothly, love the new planes and cabin crew upbeat and friendly Food ok, but that is the hardest part of it all

Finnair was ok. But some things were pretty bad: 1. Crew was not friendly, especially a crew member named, Maria. She woke me up while I was deep asleep by force just to let me know that 2 people can’t be on the same seat (my toddler and me) for sleeping. 2. There was no vegetarian option in the menu so I had to eat bread for one meal 3. They didn’t have an option for child meal

The food was delicious. There has been a major improvement here in the last few years. Excellent, friendly service. An enjoyable experience.

Awful. Delayed for unknown reason. Boarded late, part of a Tight connection ands had to go through customs and immigration. And they lost my bags.

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.

It was listed on my ticket as Finnair but there was no indication that the flight was Finnair. In fact the number was even different. There were no employees there until exactly 2 hours before so we had to wait in line at Iberia and hope

Some of the rudest flight crew I have encountered in over 40 years of flying. Despite pre-ordering a vegetarian meal, the only options provided included meat, with no other choices or substitutes offered. Additionally, the sound on the entertainment system was not working. With flight delays had only 20 minutes to make it to next boarding gate and after running most of the way made it to flight with 2 minutes to spare Will never fly SAS again and I am looking for partial refund for false advertisement.

I feel SAS is the only airline that does not let you choose your seats when you're checking in, and so we were forced into two middle seats and it was quite uncomfortable. There are not enough new and quality movies available on the entertainment system. After our inbound SAS flight being canceled with less than 12 hours til departure, the whole experience flyign with SAS wasn't great.

Didn't care much for the food but maybe that's just because I'm American and the food was very European. Would have liked a second alcoholic beverage service in a 7-8 hour flight. I was offered two wines to have with dinner though and should have accepted both. I didn't realize they would only offer alcohol once. Lights were never turned off in the cabin for sleeping. Flight was delayed several hours with zero explanation from SAS. However, the flight attendants were fantastic. We were traveling with a friend who needed oxygen and they were very attentive and helped him throughout the flight. That was greatly appreciated. The pillows and blankets are great. Gift bags with toothbrush etc so nice! This was our first time traveling Premium so alot of perks we were used to getting! The flight was smooth and I loved watching the planes location on the seat screen and being able to watch movies etc. overall it was great I would definitely recommend SAS to anyone and hope to fly with you again sometime.

My daughter always gets sick when we order the gluten free meal option. Internet didn’t work as advertised.

The flight was very cold, and the seats were rather uncomfortable. The food has been better on our other SAS experiences. Most significantly, the luggage with most of my wife's personal items and clothes didn't make the flight. Hoping for a quick resolution, but no real opportunity to speak with a Human has us concerned.

It was so hot on the plane. No air jets above the seats

Please see my comments for the flight from Chicago to Copenhagen

We were sitting in SAS plus. Super friendly, service that went above and beyond on a Full Flight too! Meals were deliscious and trays were cleared promptly. Generous drinks offered throughout the flight. Would like to suggest better movies on offer to watch.... In all genres and maybe more cooking shows? There was only 1, Nadia's Everyday Baking... Thank you

This was my first time flying SAS and used them for 4 flights. The crews, flight and communication was outstanding. I flew premium economy and was extremely impressed by their SAS lounges. I will 100% ise SAS again. Everyone was so pleasant!

little entertainment choices. Seat/bed too firm an no sleeping mat
