Pack earplugs and a sleep mask. An N95 mask in case you are sick and coughing a lot to protect passengers around you.

Remember to make time for passport control when going back and forth. It's after security. I was a little confused as a first time traveler.

Airline reviews

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

I had bad experience with United airline. No live rep, they only have AI that respond to customers concern

Flight and crew were great. Need more legroom and do not allow seats to recline.

We arrived to Chicago nearly 30 minutes early, which was great, but then was on the ground for over an hour because the gate was not available. The issue I had was the pilot estimation was frustrating. First he said he was informed it would be 20 minutes but he said "it will probably be more like 10 minutes". After 30 minutes he came back on the comm and said it would be another 10 minutes, maybe 20. I understand he was only giving estimates but he also layered in his own gut feel. We were never told why we didn't have a gate even after our scheduled entry.

Just sat on the run way after we arrived early

The Code Share with Air Canada was not very streamlined. I had to check in at airport (not online) on the outbound and return flights

Stored my cloth purse under seat in front off me as instructed. When I retrieved it, half of it was soaked, along with everything inside it. I don’t really know how that could have been prevented because the area did not look wet, but I was not happy about it.

Phx - ORD was nice 737 with starlink and the ORD - grr was ancient bare bones airbus with not even a power port lol

It was easy to board, and the staff was friendly and helpful. What could have been better is that I shouldn't have to pay extra for a seat that doesn't recline.

Was on the plane sitting longer than the actual flight in air was, boarded at 5:45p and didn't take off until 6:50p flight was only about 30 minutes long. Just was poor experience will booking more with American Airlines.

The couple in front of me were constantly talking over the announcement from the captain and this was annoying me.

Flight was ok but the food was poor, and the business chairs were not comfortable.

Great experience in Saga Premium. Food was tasty and felt fresh. Seat was comfortable (enough) - would have wanted a layflat seat.

The flight itself was excellent, but getting to the plane was literally an exercise in pain. My wife needs a wheelchair and can only stand/walk for short periods before having extreme pain. We had to take a bus to a loading platform and use a terrible elevator to get up to the plane. Meanwhile the rest of the bus were using the stairs. This meant the people who needed to sit down were stuck standing at the end of the line while everyone else boarded. My wife was in agony.

It was amazing. I sat in First Class as a Saga Premium member, and my service was top notch. It was wonderful. I only recently joined Saga Club since I do travel to Scandinavia often and enjoy flying through Reykjavik on Iceland Air versus other ways of travelling to Europe. This was my first trip sitting in first class, which I honestly wasn’t expecting!

There were no places to sit at the gate. Most people had to sit on the floor or stand waiting for the gate to open and board. We were told we needed passport and the person hardly looked at them. Maybe for 2 seconds. No announcement made asking to board by row or group. On a 5.5 hour flight the crew only came through the cabin 2 times offering water and buy everything else. For the price of the ticket at least offer free soda! The airliner was very comfortable

Crew was wonderful. I knew going in that the seats were not lie-flat in business class, but they reclined less than I expected. To save on waste, you have to ask for which pieces of the amenity kit you are interested in, which they will gladly give to you. Flight was fairly short, so no issues. I did have one piece of luggage not show up at terminal on landing. They were great about looking for it. Found it...it actually did make the flight and was listed as "not picked up" (?????--we stayed over an hour looking for it, including in the odd-sized baggage claim.) Since "not picked up" they will not ship to my house and I have to go back to airport, which is in another town. I probably could have pressed this issue, but headed back to airport for another flight anyway, so will pick up then.

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

Comfort of seats is not good. Like sitting on a rock for 6 hours. Also no in flight food and limited beverages unless you pay is not nice. Need flight to be dark during the “night” but attendants don’t ask for shades to be lowered..

Good. Lacking overhead bin space. No food offered but you can order online or in flight and pay for snacks.

We had to be bussed to the plane. And it was raining. Not a pleasant experience.
