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

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

All went smoothly. That's what I want on a long flight.

I expected more, but they will nickel and dime you for everything. I did not enjoy flying with this airline.

Curious and efficient service ! First time flying with SAS and very pleased!

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.

Our trip plan from Kayak stated we were flying SAS. That was not true. The first leg was a Delta flight. We wasted 25 minutes before finding out to check in with the correct airline. Then our SAS flight for the second leg arrived 25 minutes late, and our third leg flight with SAS closed the gate knowing the flight delay was SAS’s fault, and that this flight would only be backed up 5 minutes. The final kicker was that between Delta and SAS, they lost all our checked luggage.

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

Scandinavian Airlines is terrible. Flight was late. Lost luggage. Rude flight attendants. Terrible experience.

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.

Ancient aircraft (busted armrests, poor cabin temperature with no option for passenger control). Garbage everywhere. Risible checking of safely conditions on landing. Also, late.

O’hsre taxi and deboarding took 40 minutes. Needed 20 minutes extra time between connecting flights to avoid running through terminal.

Flight crew was super friendly and helpful. Food was frequent and honestly pretty good. Plenty of on-board entertainment. Economy seats are super cramped for such a long flight, but the crew allowed people to get up and stretch, and kids could wander with their parents, so we all made it work. Overall a very good experience.

Standard flight with a drinks and a snack- overall very quick flight. The flight attendants were very strict, bordered on rude.

Starlink is great Crew was polite Business class didn’t get a welcome drink just water and snacks were ok

Delayed - weather wasn't bad at either end. Also sat on tarmac in ORD.

very average service no complimentary alcoholics drinks unlike other airlines such as Porter airlines No decent seats available during check-in time the day before

boarded early to only find out that flight would sit at gate for 45 min to an hour. Landed in chicago and sat on runway for over an hour before got to gate. Total delay was extensive for a 45 min flight door to door.

The flight was significantly delayed. The inbound flight from EWR was delayed departing because of mechanical problems. My original departure from CLT was 5:28 pm but due to the delay of the inbound flight, after arrival, deplaning, cleaning, boarding, we did not push back from the gate until 9:00 pm. Once in the air, the flight was smooth and what was originally supposed to be an arrival in ORD at 7:30 pm local time turned out to be 9:35 pm.

The flight I was supposed to be on was supposed to take off at 1:50 from State College. It was delayed over and over and over again until somehow I had to rebook on a flight that was supposed to have left State College at 8 am that morning but didn't end up taking off until almost 6 pm. Not only was this completely unacceptable, the "token from United" was a 15 dollar meal voucher that has to be used by today. I would personally like some miles added to my account for this inconvenience. I was in transit for 8 hours from the time I arrive at State College Aiport to when I got home. I was supposed to be home at 3 pm and I returned at 8 pm. Unacceptable. I have not been on an on Time united flight in nearly 5 years.

newer aircraft, ability to connect my headset via blue tooth for entertainment.

WE didint profit of food , but for the other think all was good

Spacious and clean aircraft. Good food. Economy will always be squeezed but thankfully I had an aisle seat for stretching exercises. Good selection of movies, particularly Spike Lee joint.

Unfriendly, 8 hours delayed, no lounge access even flying business. Don’t fly Brussels

Flight from London was delayed so missed the connecting flight. Taking 2 days to get to destination which should have only taken a few hours.

Too cramped up for the better seats I paid for.

I didn’t like my seat in my return flight from Montreal to Orlando at all; considering I paid extra for better seats. That middle seat was cramped up way too much.

Suitcase didn’t arrive to Stockholm. Chairs y comfy and not even water is offered

Bad baggage and people management at boarding forcing me to dispatch my bad despite being the perfect size and respecting everything perfectly, whereas many did not and many free empty spots on the plane as usual… making me loose time and my planned bus at arrival to go to Geneva. Costing me 100 euros extra! So Brussels airlines needs to refund me

I never board the flight. My visa was delayed and when I tried calling Kayak, no one answer and I still have not heard from anyone.

All great. Very efficient. Good emails that kept us in the know

At least one soda free, felt like I was nickeled to death.

On-time arrivals and departures. Crew helpful and friendly. Yet everything costs extra: seat selection, food, even airphones!

Friendly flight crew. Airplane (757) configured as a domestic flight (no lie-flat seats) & no advanced meal selection.

The Icelandair crew was so kind!!! Thank you for making my first trip to Paris a great one!

I am not going to fillo this out for each leg of my trip. My first review holds for the experience

I’m considering never flying with Iceland Air again. The seats in economy are torture. Now you only get water, coffee and tea for free- really? No food, not a single peanut. The passport line was insane, everyone was worried about catching their connecting flight. This was the third time I’ve barely made my connection, had to run. It can’t be that my choice is to use the bathroom (during the 50 minutes between flights) or make my flight. SO stressful! Ugh.

The most uncomfortable seat i’ve ever had on a flight

Waiting area on top of stairs before Boarding the bus wasn’t great. Took a long time to load the bus to gate.

The real reason why the flying experience with Icelandair ---was mediocre was because of not being able to enter DC airspace yesterday evening. This obviously was out of your control and do realize this is a safety issue. I did notice---that everything was being done to get us to Washington Dulles and we did arrive at Dulles SAFELY with just a 4 hour delay. Thank you!

The staff was kind and helpful. There was no food, and you needed to bring your own earphones to use the entertainment, which I didn’t know.

Everything could have been better. What needed to be wrong with United went wrong

It was good. The seats in economy weren’t bad

Very good. Comfortable and I felt well taken care of from start to finish

We were in premium economy seats that appeared to be locked in plae, No reclining. My aching back.

I don’t understand how they charge as much as they do for such a poor experience

I wish the plane had pod seating for business class. I had a window seat (8K) and I had to climb over the person sitting on the aisle when I needed to get up. Also there is no partition between the seats for privacy when sleeping. The Asian airlines have much nicer business class seating. Their seats are wider for better comfort when sleeping.

The seat space seemed small especially when the person ahead reclined but other than that, very good.

Luggage transfer in Chicago was not performed in time. I received my luggage at my destination two days later.

Food was poor quality and the screens for entertainment didn’t work properly

It was a short flight, everything was good with it.
