Airline reviews

I loved the food. The veggie option was delicious. I also appreciate the sense of sustainability with Airline's choice of packaging. Hosteses were super friendly and courtous. I also appreciate that checked luggage was included with the airfare. The entertainment portal could see some improvements. The touch screen responsiveness in Solitaire game was poor and it doesn't seem to be hardware related as other screen functions were just fine. It was hard to move cards between piles and system skipped cards from the deck. Also, there was no option for winnable vs random draw. Sudoku was cumbersome regarding touch screen, too. In addition, the difference between medium and difficult levels in Sudoku was huge. Medium was actually too easy.

This was my return flight and it was 100% different than my out bound. Better seats and great food for sure. As i was disappointed last time but this time they made up for it

Copenhaguen airport is not very efficient, signs are not clear enough. Too much walking.

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

Like the fact that the boarding was expedited. But the delay and chaos around the onboarding was not appreciated.

Seats are complete BS for 10 hrs. The guy at counter canceled our return flight from europe. Lufthansa on the way back made United look like a trailer park gathering. If given the opportunity, I will never fly united again. Lufthansa seats werent much better to be fair but the service was a 10 out of 10. Incant express how difficult umited made my trip.

It was a great experience to fly with ANA, the sit is very comfortable.

What would be infinitely better if for Kayak to not offer this flight as if it was completely different airlines rather than United and then filtering me through some creepy discount site.

In general, flight attendants were not very welcoming. Because of delays in departure and luggage handling, we missed our connecting flight. Offered a later flight on standby but available seats were then taken by 4 or 5 airline crew so slept at airport and got home next day. I am a frequent traveler, and this experience was the worst.

The flight was excellent. The crew was great. The food offerings were very good.

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.

Worst and most inattentive in-flight service I've ever had.

The 787 Dreamliner was probably the smoothest aircraft I have ever flown on. Made for a lovely trip

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

How can the airline deploy the oldest 757-200 with a broken down entertainment system and no WiFi for a cross Atlantic 7:50 hr torture chamber experience?? My seat 3A couldn’t be reclined. The footrest was flimsy and useless. And there’s no leg support unlike their newer 737-Max which they lavish on intra-Europe routes. Shame!!

Only drinks included in economy class was water and coffee seat on the 737 were hard as rock. The landing and passport control in Iceland are the worst I have ever seen. 2 hours to clear customs ???? 3 attendants at pass port control out of more than a dozen closed. I” ll never fly to Iceland or transfer through this airport again.

We had a great experience with Icelandair. Boarding was efficient and easy. The flight crew was friendly and helpful. We’ll travel with Icelandair again anytime.

The ticket was reserved in my name but not paid for by underpricer. Alaska airlines was unable to issue my ticket (could not connect the ticket with the PNR) due to an error with underpricer and I spent the better part of 2 hours at the ticket counter trying to rectify.

Terrible way of boarding in Reykjavik. Seats comfortable. Meal was good.

Unlike my prior three connections on this latest journey, this flight was fairly good. Only issue was boarding as it was once again one of those Icelandic issues of bunch up, walk in the rain to a bus that then has you run up three flights of stairs to board the plain. I was in Saga class but the bus scramble eliminates any chance you get on first and have to then find a place to squeeze your carry on into an overhead that the people in economy populate so they can grab it on their way out up front. But unlike other Icelandic flights this journey I did find more the of the business class like accommodations then the other air segments. This one found a pillow and blanket waiting for me and I actually received a small cup of sparkling wine and had a bottle of water in place. Service was attentive and the flight departed and arrived on time. Received a menu and had choices of a hot or cold meal. I choose the hot which was cod and it was good. Decent size portion, salad and a choice of dinner rolls. Beverage menu was a selection of wines, beer and soft drinks. Desert was a small Tiramisu. Overall the six hour flight was a good experience for the price point.

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.

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

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.
