Airline reviews

Will not recommend SAS for business travel. Food was so-so. Service was very good. First leg was very good. Second leg from Copenhagen to Barcelona was terrible. We paid a LOT for business class and to have seats worse than most coach seats with no entertainment and no charging available for 1/3rd of the whole trip was not acceptable. Very disappointing. I thought they were coming back in the U.S. with style, NOT YET.

I do not have a problem with the airline but both my two suitcases that were supposed to go from Hawaii to Copenhagen didn’t get on the plane in Seattle. I arrive on Monday the 21st at 10:30 in the morning. I did not get my two suitcases before Friday late afternoon that is unacceptable.

Love thiscsirlibe. So civilized and kind. Good food. Good treatment. On time. Excellent communication.

Online check in of SAS is very poor. Even the kiosks at London had system problems. Either it would print boarding tickets or luggage tags. Many other customers had problems . SAS staff was good and helped.

No choice of food. Needed to pay more even for a can of coke!!!

It was great, used to fly them a lot back 20 years ago but since did KLM as my flight route changed, but very happy with my experience and will come again!

The seats were really close together and hard to get comfortable. The food was okay. The cheese was amazing! I loved the cold towels they gave us.

I really enjoyed how clean and big the aircraft was, as well as how friendly the crew was.

Painful seats for a 10 hour flight. There’s a very hard flat board in the seat that goes up to half the back and after 7 hours it gets impossible to find the right position to avoid the pain.

I love it the scandavians know hospitality travel and are very friendly peopu

Once we got in the air the pilot made up some of the time of the delay. So that was really nice.

We had a layover from YVR to Denver. We bought 4 bottles of Absolut Vodka at the YVR Duty Free for $116.20, after going through security and American Customs Pre Clearance at YVR, Vancouver. When we landed in Denver, United put us behind the American Customs as well as TSA again for some reason. We were forced to go through American Customs and TSA again. TSA confiscated our rightfully owned Duty Free Absolut Vodka bottles. Because United incorrectly forced our flight behind American border and TSA again, we missed the connecting flight. After United put us on a later flight, we eventually arrived in Chicago very late, with hardly any sleep. I am looking for compensation from United for our incorrectly confiscated Absolut Vodka bottles worth $116.20, as well as compensation for incorrectly putting us behind American Customs and TSA again, causing us to miss our connecting flight, making us arrive extremely late in Chicago.

Excellent flight. Boarding was efficient and departure was on time. Smooth flight with on time arrival. Deplaning was also efficient.

It was delayed instead of departing at 9:20pm, we departed at 11pm… putting us in Columbus after 2am! It was awful. Had I known about the delay, I could have spent some time in the United Lounge… I was starving because I started my journey in Budapest… so I was exhausted and hungry. Plus I had to make new arrangements to be picked up at the airport in Columbus, instead of midnight it was 2:30 am after getting luggage and out of airport. Not feasible. I would have just stayed in Chicago for the night and gotten a morning flight.

It was great, I’m very grateful for the pilots and crew flight attendants for everything.

Evidently, my seat had the only broken TV. I couldn’t plug it in, get it to come on, or watch anything, and of course, no one could fix it while we were on the plane. The service was good and the boarding was quick

The boarding of took of late.The presentation of the food was horrable as was the tast of the food was cold and tastless.

Delay and keep changing gates. I have to run around from B to C then to E.

I was charged for my daughters bag when I am supposed to receive two free checked bags with my United Explorer card.

The schedule to Moline changed 5 times. The gate changed 6 times. That is a pathetic way to run an airline. No wonder that no one in our company flies on United Express to or from Moline. Changes happen most of the time. I learned my lesson on this trip…never again!

Real smooth and easy, Real good leg room in coach!

There labor disputes cancelled my flight less than 24 hours before my boarding time but there customer service/website was easy enough to navigate and they rebooked me for no upcharge.

Re luggage I carried a backpack only. I did not check any bags in. However there were other passengers with carry on luggage going in the plane. My question is why are others allowed to have a carry on luggage inside the plane? Shouldn’t they have dropped it off at the gate? I’m asking because I could have brought the same thing instead of a backpack only. Please clarify for future reference. Thank you.

Like the service. Very hard to communicate or contact when have problems

Very bad, flight was cancelled due to strike and staff was unable to rebook us

They rescheduled me and I had no issues with the new flight

Air Canada is my new fave airline..I plan to use when I can. No complaints at all just rave compliments for the staff and airline.

Strike pissed me n stranded in middle of no where

Check in staff was incredibly rude and condescending. When I arrived at the gate I had been charged $125 for a checked back. I did have or check a bag. When I brought this to the attention of the staff member who checked me in, she said that she made a mistake and there was nothing she could do about it. I asked her to remove the charge and refund credit card, she said she could not and that I had to call my credit card company to contest the charge. I called Air Canada customer support, was put on hold, after 43 minutes a received a messages stating customer service was overwhelmed with calls and was then hung up on.

Refreshments and Air Hostess was good. Issues with customs in Toronto caused flight to depart and left me behind twice. Vouchers for delayed flight needs to increase.

Best smelling onboard bathrooms ever. Even after use the whole flight. Biggest overhead bins. Most legroom in economy class. Great Icelandiic music. Really nice staff. Icelandair is awesome! (Don’t fly Air Canada! During the strike they lied about no flights available (I booked this flight myself) and hid the process to get money back on their website by obscuring menu titles, then made it difficult and time consuming to fill out. I’m Canadian. Don’t trust Air Canada!

It was good. The air plane is clean and staff were friendly.

Worst airline I’ve ever flown. Delayed 5.5 hrs, missed connecting flight, and missed an entire day of vacation. Zero customer service

Everything sucked. No food, one small glass of water, a tiny coffee, 5.5 hour delay with no customer service. Would never recommend flying them.

The crew was wonderful at check in, the gate and on board. Felt the luggage had more room than the passengers. The seats were smaller than most domestic U.S. airlines. I'm only 5'2" and I had little legroom. There were only 2 bathrooms in coach. Needed more. The flight was very smooth but not the most comfortable.

There was no lounge at Boston for us to use. Typically flying first class overseas comes with lounge privileges. The seats did not recline even a little. My headset only worked on one side. I felt like I was flying on Ryan Air, not Icelandic Air.

The flight was delayed and as a consequence we missed our connecting flight. Were stuck for another 6h in Reykyavik. Appreciated that we got a generous food voucher at least. Would have liked to see more information upon arrival including a person waiting for connecting flight travellers and informing already that we will not catch the flight and directing us to the office dealing with the matter; unfortunately that didnt happen and we hence first needed to find out whether flight had indeed left already and then locate the adequate office to help us with booking us on the next connecting flight. Also my suitcase broke and it is not clear whether it is happened on the leg with Iceland Air from DC to Reykyavik or on the leg with Lufthansa from Reykyavik to Frankfurt. Finally, understood that it is a low cost company but at least provision of earplugs for free would have been nice, instead of making them buy.

Great experience on Icelandair flight from Newark to Amsterdam by way of Reykjavík. Courteous and professional staff. Food was solid. Service - outstanding. Cabin was a little warm.

Good service. No complementary food for international flight. WiFi kinda pricey. Got the job done for the right price.

Still one of my favorite airlines, but the entertainment options were a bit lacking. It didn't help that my screen didn't work on one of the legs of the trip.

Boarding was efficient and quick, crew was very attentive, seats were comfortable.

Everything was very good! I personally struggled with the heat in the cabin for the first 2 hours

Very caring crew on board. Didn’t have dinner as I was sleeping. Was seating in the emergency row so I had comfortable leg room

Had a nice little suite although I couldn’t close the door (but I didn’t ask anyone to help). 5K is a nice seat and very private (you look in on first class). Enjoyable flight and nice crew.

There was a slight delay. Otherwise, everything else was satisfactory.

Although the crew were great and the good nice, I might as well have been on Ryanair for the amount of space I had. Not good enough BA. I’d rather pay more and not feel like a human sardine.

The company that I bought my tickets through, Cheapflightsfares, failed to provide my confirmation information in a timely manner, so I was unable to check on at the country and therefore unable to make my flight. As a matter of fact, I STILL have not received the confirmation. After having read more and more reviews about the company, Cheapflightsfares appears to have scammed hundreds of hopeful travelers out of thousands of dollars. Please look into this company and, for the sake of anyone planning their next trip, stop allowing them to do business through you.

Love the A380 - loads of room. Headphone socket on my seat didn’t work. Sounds like a trivial issue? Well when flying long-haul the in-flight entertainment is what keeps you going so when it doesn’t work it’s a disaster. Pay attention to the details please BA. Spoiled what was otherwise an excellent flight with the usual brilliant crew.

Crew were fantastic can’t fault them at all. Couldn’t do enough for us

Crying baby the ENTIRE flight. Not your fault, but I paid 2700 for a premium economy ticket and it wasn't worth it. should have just stuck with coach. flight attendants very mediocre - minimal effort. Plane didn't seem very clean. Didn't have any cleansing wipes - most airlines give you this when you board. Flat screen scrolling didn't work. Toiletry case a joke - why bother at all?
