Being seated next to the engine was awful! I was nauseous the entire trip from pre-take-off, flying to landing. The engine vibration was very strong!

Being seated next to the engine was awful! I was nauseous the entire trip from pre-take-off, flying to landing. The engine vibration was very strong!

The crew was the best I’ve had the experience of flying with. A misbehaving child was making things difficult for me with bopping my tray table, taking my snack, and continually tapping or bumping me. The crew quietly and respectfully moved me to another seat, and thanked me for my patience. They couldn’t have been more kind. Their professionalism really stood out to me and I am more than happy to leave a great review for them!

I would have appreciated notification that our flight was moved to another gate LAST MINUTE so that we would not have missed it. We got no such notice and had to spend another night to catch an available flight in the morning, which was huge inconvenience. We will never fly Alaska again.

Flight was delayed 2 hours. It was too cold inside the cabin. My seat mate had no jacket so she was shivering the entire flight. The stewardess says there’s no available blanket.

The airline was way too cold. We were freezing, I don’t know if that is normal. Overall it was pretty good flight. Always flown Alaska Airlines and I am not changing.

Mediocre is best way to describe. Bare bones narrow seats, Dirty pulldown tray, unfriendly cabin crew who were in a hurry to serve tiny drinks and tiny snacks. (Compared to much better Hawaiian Airlines experience, .. no comparison!)

I wasn't impressed with the entertainment selection, and the snack sizes were small. But the entire crew was professional and did a great job. For that I would fly Alaska again.

It was really good and that's why we choose AA over other airlines.

In economy, there was actually a decent amount of legroom and it was shocking to be in a bathroom that actually had a little bit of space! It was far more spacious than Most airlines are today. It was pleasant because of that.

Seats are uncomfortable but let room was adequate. The snack is pretty weak and the staff not particularly friendly.
