Friendly flight attendants and reasonable good food. Quick service throughout the trip.

I WAS CANCELLED ! I thought entire flight was canceled but it was still ongoing and I was only canceled as a passenger and one day before my flight with really poor "choice" of next flights that completely ruined my family event. Absolutely disappointed by SAS. Will be avoiding this airline now

The flight was pleasant with landing and take off being very smooth. Toilets were a bit busy at times but crew was very accommodating. Food service was quick and hot. The connecting short flight was full and there was not room for hand luggage.

Flight crew was very kind and polite. They had to deal with an unnamed issue right beside me, and did so with respect.

No crying babies the whole flight would be nice. Impossible to sleep. No free snacks , only the main meal

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

Seat was lumpier than I’ve ever remembered it to be although comfortable when tilted back. I don’t recall being that hungry after being served food from SAS before. Flight attendant on the second flight to Aalborg seemed to be having a bad day.

On this shorter leg and with an older plane, just mediocre. On the connecting long haul (Chicago to Copenhagen) everything was great.

My outbound flight was incredible... Milan to Chicago. The crew worked so well together. Each passenger felt spoiled and incredibly valued. The crew on this flight was fine. Nothing to complain specifically about but could not give top rating only because of the superior crew, hospitality, warmth we felt on the first flight. Unfortunately. You managed to lose my luggage ..my only piece checked in. Lost in Copenhagen so I had the added stress, time wasted to file the report. To make things worse, Italian rail decided to strike that Sunday so I could not take the train as planned back to Switzerland. Horrible waiting time and poor communication for boarding substitution bus. The substition bus to the town of Stabio did not run on time and was late about 40 minutes.

The flight was cancelled early on and messed up the whole vacation and hard to get a refund from Kayak as they owned the ticket and of course they did not believe that SAS cancelled the ticket. Definite bad side to third party. SAS had rescheduled but overlapped the connecting flights. That did not work. Flight was cancelled long ago but Kayak still has it. Like it was taken? Bad IT ? Or all assumptions and no follow up which is the whole IT world. It needs to wake up and be more efficient. Especially as the world is going, there will be no freedom to do anything. And we will be living like the Middle Ages. Yeah, go read up on that while you still can.

I especially enjoyed having a lightly packed flight which enabled me and my wife to occupy a three seat area with nobody in the middle seat.

The seats are very small, that is all the staff did a good job.

It was great. The staff is always helpful and polite. The app is great and makes the whole trip and process so easy. They even offer a step to step guide to your correct terminal. And they keep all the information you'll need updated. Anything you can think of! Great experience.

Perfect. On time and the weather was perfect so we came in a few minutes early.

On time. Carry on and personal bag was accommodated on the plane. Entertainment was accessible without bringing own device. Whole can of juice was provided rather than a pour.

Price was crazy watch it if you Chan he your flight

On time, easy boarding. Anytime you sit in an economy seat, it’s uncomfortable. New plane and the bathrooms were in the galley at the back of the plane which seemed odd.

Terrible service - they don’t want to be there and bad food. Entertainment system in economy from the 2000s

No drink service but there was no N/A as an option to choose. Seats were extremely tight. I am under 5.5 and I bumped my knees have no idea how taller people could manage.

Flight delayed, last seat on the plane, no arrival Gate available due to the plane departing late

We did not fly on American Airlines from Chicago to London. We were rebooked on British Airways (by American Airlines) and our luggage was left behind. A full day delay and lost luggage.

I have posted the comments in the first flight leg.

First class snacks - stewardess gave out multiples to everyone until there was almost no selection left when she got back to me last in first class cabin. Nothing left that I would eat.

My feedback from the trip to Columbia to Chicago was meant for Chicago to Denver.

The WiFi was out gr entire flight. Had to Diane for almost 1 hour to wait for a gate to open up for plane to dock. Very bad experience.

After boarding, the AC was shut off on the flight. At business class, I really could not breathe. I was absolutely dripping sweat. I was told by the FA that there was nothing they could do but I could stand by the door until departure. So, that's what I did. I was clearly in the way while the FAs were trying to do their work, but I had to be able to breathe. After that, of course, I had sweated up a lot so was very uncomfortable for the six hour flight.

DELAYED AGAIN and AGAIN and AGAIN - not only that, you delay in 20 minute increments for hours and hours instead of having an accurate delay understanding.

AA was fine....the overall experience was subpar, but not due to the airline due to broader issues

No ground air conditioner for the plane. Very hot and humid prior to take off which was an uncomfortable period of time.

Check-in process was poor, very poor, only one person to check-in all passengers, so if one passenger had a check-in issue, all other passengers were delayed. All check-ins should have two airline staff to check-in passengers.

Movies were old and third rate. Very poor on a seven hour flight. Food was OK but not business class caliber

We got to the runway and had to go back to terminal to have plane worked on, which is fine, but the 40 minute connecting flight was already gone because of this delay and had to wait 5 hours to get on a different flight and only got a meal voucher which I didn’t see the email until after I had already ordered and paid for food. I feel I should be compensated.

Horrible. My dad was recently hospitalized and diagnosed with lymphoma and Icelandair refused to refund flight even though I had a letter from his physician.

I paid for our seats and when we boarded and went to our seats it was the last row. I would have never paid for my seats knowing I’m sitting in the last row. The airline must have moved our seats and I didn’t realize it when we checked in.

Iceland air transfer was bad. They lost my luggage and I just received it 11/1

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

Everything sucked. No food, one small glass of water, a tiny coffee, 5.5 hour delay with no customer service. Would never recommend flying them.

Our three ski bags did not arrive and are still not delivered, one full day later. With one ski bag not traceable at all. I would not fly Iceland Air again.

Great crew, bumpy landings, two-hour wait for baggage with no communication or explanation. Will not fly again!

Decent service - nice seats. Crew were not overly attentive but can’t complain overall for the money

It was a safe and smooth flight. Members of the crew at the second level, business could have been more polite and engaging.

I was booked to travel from Dallas to Nairobi via Chicago and Brussels and had been issued boarding passes for all three segments of my journey. At the boarding gate in Dallas, I was required to check my carry-on luggage due to limited cabin space. Despite my attempts to explain that I was traveling internationally and would not have access to the bag during transit, my concerns were not considered. I also informed the staff that I did not have a padlock to secure the luggage, but this was disregarded. Consequently, I had to hastily transfer essential items from my carry-on into my handbag. Unfortunately, the onboard experience on the Chicago to Brussels flight further reinforced my dissatisfaction. The cabin crew appeared disengaged, indifferent, and lacking in attentiveness, resulting in a service experience that fell well below my expectations.

Flight was on time and got us to destination quicker than scheduled.

I have very bad experience with United because Vince two weeks that I did not receive my luggage yet

It was okay. Mothers with rowdy children should be invited to sit in front of them.

Good food, overall very comfy. The flight was full so obviously not optimal, but it is what it is.

Flight was delayed by several hours and then cancelled due to weather. But Staff was very helpful getting me on a different flight. United should offer food coupons and tooth brush and paste for stranded passengers

I had a good comfortable seat. There was nearly an hour delay. There was an accident with the champagne, but I was well compensated. These things happen sometimes.

We missed our flight. There was not enough time built into the layover to get through immigration, customs, bagclaim, bag rechecking, and the long trip to another terminal and gate. Kayak really screwed up. We took the bus up to Wisconsin and then were picked up in Brookfield by private car. It was lucky we didnt miss the last bus out.

I tried both on line and by calling the Customer Service line to arrange for a special meal as i have food intolerances. I was under the impression from your service representative that I was successful. I was not. I cannot eat spicy foods and get very ill if i eat bell peppers. I could not eat either menu choice and no special meal was actually ordered. ( your representative tried to order it for a flight that did not have meal service!!! - found this out later). Your wonderful cabin crew managed to put together a fruit, salad, roll and cheese tray for me so I had something to eat. WHY WOULD YOU SERVE SPICY FOOD, WITH NO MILDER OPTION,ON AN INTERNATIONAL FLIGHT???
