Our gate agent was absolutely amazing. Personable, kind, and helpful. She alone makes me want to return to use Alaska Airlines.

Our gate agent was absolutely amazing. Personable, kind, and helpful. She alone makes me want to return to use Alaska Airlines.

Don’t fly with Alaska if you have a layover in Seattle. Guaranteed to screw you over. We waited at terminal S3 &were >2 hours delayed(mechanical issues)and told to change terminals to a different plane that required riding 3 shuttles to get to new terminal N14. Then they delayed the flight even further and changed gates again. when I went to the customer service in terminal N, the manager turned me away without apologizing & refused to assist me but mandated I leave her alone as her shift is nearly finished and insisted I totake another 2 shuttles to terminal C so I can just talk to another service rep while dragging my family of 4/ kids in tow.

Everything was good. Please have a wheat free option for snacks in the future.

Not delay for a few passengers. That was uncalled for. If idiots can't make the flight on time thats their fault. Why should I be punished for them? No more holding the plane for one or two people

How can I review what was denied to me. Instead of offering to let me pay for the ticket I got booted of my flight with no way home and no choice but to purchase another ticket for 12 hours later. Filing a complaint with the DOT

I like them since I live in Alaska and I don't have much choice

Coke zero offered...good. The proptness of flight was late. This has been a everytime thing for my last 9 flights. And is putting alot of pressure on my connecting flights. Not a bit punctual. I am always early, but Ak. Airlines is not. And people i happen fly beside, parrot the same thing. The baggage delivery to baggage claim, is not prompt. Its slowwwww. The seats are poorly padded, very crowd. We need more room, not padding the airlines bottom line. Its like a cattle car. More leg room, more side to side room. And attendants need upgrade of verbal skills. I have been faithful to Ak. A., but it will change if changes are not made. Not the only planes in the sky.

We were very late to take off, late exit plane, and luggage took a long time.

Great if it’s not a long flight in coach.

we booked with Alaska but the flight was operated by AA, and this meant we were unable to check in online. We arrived at the airport to check in over 3 hours before the scheduled flight time, but were not able to be seated together (2 people on the same booking). So we had middle seats solo on a 11 hour flight which sucked

The layovers / connections were too short and too long. I SPRINTED to make the connection from OSL-JFK and then SAT for over 6 hours from JFK-BUF. I don’t mind a longer layover more than I want to RUN to make my next connection

Our vacation started with horribly, 48hr prior to departure SAS airline cancelled our return flight giving us little to no alternative options.

The layover was very long. Other than that, great trip so far

Elderly traveler with disability was bumped from extra legroom to economy with little legroom. He couldn’t bend his knee to fit in the seat. Very uncomfortable for a 7 hour flight and will be reported to DOT. Then the food was disgusting. Boiled chicken with boiled rice and steamed veggies. 3 slices of carrot and one broccoli. We couldn’t eat it. No salt or pepper provided. Disgusting.

Payed $140 xtra for seat arrangement Did not get the preselected seats neiter outbound nor inbound. Absolutely not worth the xtra money

Gate agent in Atlanta refused to let me take my carry-on on the plane even though I met weight and size requirements and the plane was half empty. My ticket clearly stated that I was entitled to one carry-on and one personal item. Will not fly this airline again.

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.

When we arrived in Bergen and opened our suitcases, we were shocked! We checked 2 of 3 suitcases and the contents of these 2 suitcases was completely wet!!! It was raining in Oslo and Bergen, but not a hard rain. It seems that someone had gone through our suitcases. There was even sand in the suitcase such that everything had to be laundered when we got to Bergen! We had plastic bags in our suitcases and they had been opened and the interiors of the bags were wet!!! Our valuables were all in our carry-on so nothing was actually stolen. What happened here was unacceptable! There is someone working for Scandinavian Airlines who is not honest and really messed things up for us. Not so sure I would fly SAS again… Marna Skaar

Flight was delayed slightly but was very smooth. It was a short flight but comfortable.

Little space and no pad provide for lie flat seats in business, Movies were limited and grouping very strange.

The flight itself was excellent, but getting to the plane was literally an exercise in pain. My wife needs a wheelchair and can only stand/walk for short periods before having extreme pain. We had to take a bus to a loading platform and use a terrible elevator to get up to the plane. Meanwhile the rest of the bus were using the stairs. This meant the people who needed to sit down were stuck standing at the end of the line while everyone else boarded. My wife was in agony.

It was amazing. I sat in First Class as a Saga Premium member, and my service was top notch. It was wonderful. I only recently joined Saga Club since I do travel to Scandinavia often and enjoy flying through Reykjavik on Iceland Air versus other ways of travelling to Europe. This was my first trip sitting in first class, which I honestly wasn’t expecting!

There were no places to sit at the gate. Most people had to sit on the floor or stand waiting for the gate to open and board. We were told we needed passport and the person hardly looked at them. Maybe for 2 seconds. No announcement made asking to board by row or group. On a 5.5 hour flight the crew only came through the cabin 2 times offering water and buy everything else. For the price of the ticket at least offer free soda! The airliner was very comfortable

Let's just say I won't do it again.

1. No food on a 8 hr flight is a travesty! The fare was not that low. 2. The entertainment was pretty bad and you had to buy headphones!!! 3. Only 2 toilets for the whole Economy section!!

If there was a disclaimer regarding food service or lack thereof, l missed it. If l had known l would have prepared better. Same with transferring at Reykjavik. No information about disembarking via stairs into rain, slush and puddles deep enough to swallow a foot. After being treated to haute cuisine restaurants and warm inviting environment during the flight, the airport is, let’s be kind, disappointing. Plane was comfortable, Airbus, staff were welcoming enough. I would likely try the route again. Maybe have a night and day in Iceland. Maybe not.

For an economy lite experience, it's by far the best I've had. New planes, clean, great destinations. Very happy to have discovered Iceland Air.

Smooth efficient airline. Think they should have their own bag drop as the queue took 30mins to bmscan and drop

did internet check in but still had to get checked in at the counter and this was not the first time. Bummer!

Paying $75 for my bag is disgusting. Got off ground late so I missed my connections. Kept us waiting for passengers in the cold. Will not use them again.
