Pack earplugs and a sleep mask. An N95 mask in case you are sick and coughing a lot to protect passengers around you.
TFlew with Scandinavian Airlines-May 2026
Go through passport control as early as you can. The wait was very long and people nearly missed the flight.
JdubFlew with Scandinavian Airlines-Apr 2024
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.

Amazing, crew are very friendly and they gave us blanket and sleep aids and plenty of drinks and snacks

Excellent comfort, service, boarding, deplaning. Bad meal (preselected vegetarian) but only vegan was available from a passenger cancellation. Bland and not very filling except for thin passengers.

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

We left nearly 3 hours late...so that was not a good experience. We boarded and then ended up about 1 hour stuck at the gate. Not a good experience.

I appreciate how quickly and kindly the people at the gate at DCA accommodated several of us who wanted to switch from the 6pm flight to the 5pm flight at the last minute. The flight crew was helpful to us too (dealing with luggage).

Went from a plane with free internet to a plane with paid internet. The entertainment screens didn’t work. Crammed in the back and the crew hit my knee with the cart really hard - it hurt. No apologies. I’m still limping today.

Waited on tarmac to take off for approximately 15-25 minutes. When landing, the taxi to our gate took a similar amount of time. This happened on both of my United flights.

Fine except from Chicago to moline three different gate changes and flight times

When booking, the connection times seem fine. But in reality, my two connections were cut short by the first leg being delayed due to issues at the destination (too much traffic going into SFO, ORD) and it became extremely stressful.

Promised internet. Tried for nine hours to log in, no way. I tried the free option, I tried the paid option, I tried restarting my phone.. several times! Very aggrevating as I was trying to keep up with an emregency medial issue with my dad, but could not because the promised service was not available.

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.

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

The plane is extremely cramped. Water is offered for free. It's pretty bare bones. Staff was nice

Paid for seat upgrade that didn’t happen. Large luggage charge. No food or snacks without paying extra. Tight seats - even on row 11.

Everyone at icel air just passes the buck if there's a problem which there was they don't want to know about it any company can be good if everything goes well it's what shows is when something doesn't go well how they handle it and trust me Iceland air does not know how to handle any kind of problem

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

They had a 4 hour delay and left my luggage in Iceland and it didn’t arrive in Portland until 11/1

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.

Highly disorganized company, poor customer service. Packed seats on a 737 for a trans-atlantic 9 hour flight. Greedy company policies, no meal or snack provided for 9 hour flight.

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