My bag was gate checked in Seattle and I was told it would be at the end of the walkway when I arrived in Idaho. It was not and I had to get it from baggage claim. Southwest Airlines will gate check a bag even if they have room for it in the cabin. I like that a lot. Seattle Airport is not that easy to maneuver. Indianapolis is one of the easiest airports to navigate.

Truly, everything was professional, and extremely friendly with lots of smiles from all the staff. My only complaint is that both coming and going from San Francisco to Seattle and back the public announcement system on the airplane when I was sitting in the exit row was so loud that it hurt my ears, and I was not the only one I did report it to one of the stewardesses who thanked me and apologized, but truly Alaska Airlines is my favorite domestic Airlines by a far shot

Cheeseburger was good, but other sides were awful. Attendents were great! Flight was good, except for changing gates 4 times and flight being delayed over an hour..

Boarded a little late as they fixed a toilet, but still landed on time. Alaska drop bags process is a little like a cattle drive or bus process in Seattle, but the rest of the travel experience was great.

Flight was early and boarding the plane was flawless. The temperature on the flight was warm and my vent didnt work for air blowing. I only had a biscuit as a snack.

Uneventful, which is perfection in airline travel. Everything happened as it should and when it should. Flight was short so no food. I could have used the App to watch something but took a nap.

Was OK but my seat was way in the back(on a premium economy itinerary)

Alaska did a great job of accommodating my needs and treating me fairly. I appreciate their willingness to smile and be caring.

Flight was way over-booked and the turn over too fast from the last flight to the next. We had delays both ways due to storms -- not our trip but the one the plane had taken before us. Just seemed like poor time management. Shouldn't there be a slight buffer built into the schedule? And every seat was full to the detriment of loading.

Delayed 2-3 hours. We boarded one plane, then had to deplane, and board another. Got to Houston 2 hours after the scheduled time at 2 am CST.

Movies were old and third rate. Very poor on a seven hour flight. Food was OK but not business class caliber

Although the flight from JFK to Keflavik is not inexpensive, Iceland Air offers nothing but water, no soft drinks, to passengers without a charge. The seats are uncomfortable, there is no leg room, and there was no available internet to purchase.

Was hard to sleep, but other then that everything was good.

I had no idea that my ticket only paid for my right to get on the plane. They charged me $130 for my carry-on bag because it was 1 inch too big she claimed but it wasn’t! Then they wanted another fee for everything. I had no idea that Icelandair had changed to such a bargain basement airline. I was very disappointed.

The staff was kind and helpful. There was no food, and you needed to bring your own earphones to use the entertainment, which I didn’t know.

Seat was hard and uncomfortable and the temperature too warm and uncomfortable.

Everything was good. Only issue comes from being vegan and flying. The food options are super limited.

Overall good for an economy fare. IMO the movie selection could be improved. Great that you can now connect bluetooth headphones to the entertainment system.

7 hours 15 min flight from SEA to Iceland with no inflight entertainment and no power to charge your own devices, also no meal service, not even any snacks/cookies. You have to buy food and the options are extremely limited (i.e. ham and cheese sandwich and spicy cup noodles). I didn't think Iceland air was a budget airline, maybe I was wrong, the cost of the ticket didn't feel like it though.

Very nice flight, easy connections in Keflavík, and friendly crew.
