My biggest recurring disappointment is that I buy a pre-assihned seat while pucrhasing the ticket and then when checking in it disappeared and I have to buy it again. That's very disappointing and actually a reason I will actively avoid SAS in the future

My biggest recurring disappointment is that I buy a pre-assihned seat while pucrhasing the ticket and then when checking in it disappeared and I have to buy it again. That's very disappointing and actually a reason I will actively avoid SAS in the future

SAS cancelled my flight SK910 on Sep. 21,2026 because a construction crew from New Jersey Transit accidentally cut through a fiber optic cable which enabled the control tower at Newark Intl. Airport to communicate with all flights. Over 600 flights were cancelled including mine. My boarding code was B2WJMJ, I demand a refund of all monies spent toward this reservation!

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

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

The first leg of my trip the Republic Airlines aircraft was late due to a maintenance problem. Then I called United to reroute. Their reroute airline lost my bag but found it and returned it two days later. Hopefully my return trip home is better.

There was not even a single time where united airlines from lga has made to the gate straight , 1 hr if delay today

Flight from Munich to O’Hare was great but it was on Lufthansa, a UA partner. It had more legroom than United, seat slid forward to make reclining more comfortable, they offered free drinks. United offered none of this. Oh and the food was superior to United’s which honestly, sucked.

Requested for warm or hot water because of throat pain, it was denied. The entertainment system was hung, requested the crew to turn it off, instead of turning it off they rebooted the device. It was stuck again, no one bothered to check.

Horrible on the chicago end. They change hates then there is a plane at the new gate so we can’t pull in. Then that plane has mechanical issue and needs to be pulled back to the gate but we can’t get to another new gate due the other plane being in the way. Horrible gate management which will cause many customers to miss connections.

Fantastic experience once again flying with United! There was great communication from the cockpit and one of the flight attendants went out of her way to get my two little kids some special treats which elevated our travel experience coming home.

The employees seemed impatient with their guests. It seemed like they were giving us orders, instead of easily assisting. Our flight was delayed waiting on a flight attendant. It was alright.

Liked the excellent United crew, the food selection, the comfortable cabin and the excellent movie and tv shows selection. The interface on the screen is also excellent and gives the option to let the crew know to wake you up for meals, or not. I disliked the onboarding experience at the Brussels airport. The process is convoluted and was not explained to any passengers. I also don't understand why thee is an additional security screening when getting off the plane from Africa, when there was none when getting off the plane from the US.

It was a good flight. The entertainment could be better.

roomiest flight in economy I've taken in years. Excellent experience!

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. To my surprise, upon arriving at Chicago Airport, I observed numerous international travelers boarding with cabin bags that were significantly larger than mine. This experience left me extremely disappointed and led me to decide against using United Airlines for future international travel, a sentiment I have also shared with friends and family. 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.

I want to highlight the crew members and their excellent work and professionalism. They work hard to make a long trip the most comfortable as possible, the food and drinks they offer are pretty good. And they are always asking if you need something else. I have had experiences with other airlines where you have to basically beg for a bottle of water. This is not the case. Highly recommended!!!

the blanket was great and pillow helped. really need a toothpick packed with meals

Very comfortable plane. The food was very good (for airplane food). The crew was great

The legroom was lacking and the entertainment system lacked adequate selection of older films. Modern films are generally not very good.

Perfect airline, super friendly, great service, tasty food. Would fly again.

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
