It was ok but no WiFi I think I’ll fly Iceland air next time

It was ok but no WiFi I think I’ll fly Iceland air next time

I feel the service staff do not treat American customers well. I also feel there may be discrimination against minorities.

Yes avoid JFK airport at all costs. A horror to navigate.

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

1 flight cancelled Had to fly out of different city Flight at new departure city was delayed 3 hours causing us to miss connecting flights. By the time we did make it to Prague our luggage did not. Had to wait day and a half for luggage to be delivered. Customer service was not good. Agents did not arrive at gate until 5-10 minutes before boarding

Awful. Delayed flights, missed connection to Toronto. Hotel vouchers were for already booked hotels x3. Giant waste of my time

Boarding was great, and the crew were very friendly. The seats must have been a bit on the older side and you could feel some of the seat components through the padding. Also, the plugs did not work on the row's entertainment screen or charging ports. Checked bag was transferred for connecting flight, and we appreciated how early we had the connecting gate information.

Very easy ! Use the kiosk and bag drop and right to security within 10 min

Prefer not to have an almost 3 hour delay with useless communication that wasn't accurate.

Over 5 hour delay with minimal updates or ability to standby for alternative flights. During boarding and 1 hr+ wait for takeoff, seats were drenched w water from air conditioning condensation and always leftover crumbs on carpet and seats

I flew from Barcelona to Chicago on UA yesterday. The flight was on time, the pilots did a great job and the flight attendants were super nice. All of them. Also food was good, and the drinks, including wine were served a few times during our flight. I highly recommend this airline.

Boarded early, left early, arrived 40 mins early! A win win for me!

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.

We paid for saga class, which is the business class for international. My seat was broken and did not recline and my monitor for in-flight entertainment was broken.

The flight itself was fine, even with a one-hour delay leaving on the Reykjavik tarmac (the lost time was made up during flight). Our experience at the Reykjavik airport on arrival was terrible due mostly to the one hour it took for passport control. Only two stations were open for our category, and the room was full with a huge crowd.

Awful. The Iceland airport was a complete mess. Boarding was a chaotic, the seats were awful, there was a group of rowdy 20 something men in our row hooting and hollering, ordering alcoholic drink after drink. Yelling and laughing at the top of their lungs and the crew just went along with it. Passengers complained to the men, asking if they could keep it down (it was a night time flight so people wanted to sleep). They never listened crew continued to laugh with them, flirt with them and serve them more drinks. No free food or snacks, seats were horribly uncomfortable. Worst flight I've had in a long time

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

Friendly flight crew. Airplane (757) configured as a domestic flight (no lie-flat seats) & no advanced meal selection.

The Icelandair crew was so kind!!! Thank you for making my first trip to Paris a great one!

I am not going to fillo this out for each leg of my trip. My first review holds for the experience

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.

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.

Luggage transfer in Chicago was not performed in time. I received my luggage at my destination two days later.
