in-flight wifi was not working well. also the cabin temperature was a bit hot.

Morbidly obese dude took half my seat. Sore shoulders back from being squeezed. Shame on the airline for not making this guy purchase two seats

Flight was cancelled last minute, had to change and buy another ticket to united airlines, made it 10 minutes late to my international flight and couldn’t get any reimbursement what so ever due to “Weather”, yet all other airlines except south west were running Just fine. Every single time I fly Alaska, it’s a huge delay or cancellation. My hope is that more people avoid this airlines all together until they actually improve.

Nice crew, healthy snacks and drinks available. Flight to Seattle was short and comfortable.

I like flying Alaska Airlines. I think the staff are happy, the plane is comfortable, the entertainment reasonable, the food acceptable.

The flight was good, comfort in the seat was good, drinks were good, entertainment had a large selection to choose from. I really liked the multi function of the tray tables, I hadn't seen that before. My only downside was that I wasn't able to have your snacks. Please have a wheat free option for a snack.

The flight was a disaster. It is a 40 min flight and we waited to the tarmac for well over 90 min with no updates, while the crew tried to reconcile the seating chart of people on the plane to what their phones showed. Terrible communication, systems and experience. I would do almost anything to avoid taking another Alaska flight after the experience last night.

I had a medical incident on the flight. The crew was very responsive and kind, making the situation as "good" as possible. (I believe they were overly cautious, but it's understandable.) My only complaint is that the seats are too small. I was so cramped for so many hours, that it exacerbated my medical incident. I will probably not be able to fly in coach anymore, and cannot afford otherwise, so it looks like flying is a thing of the past for me.

Experience overall was great, we didn’t land upside down like a Delta plane once did. The entertainment section didn’t apply for me, but I put excellent I think anyway.

Attentive, caring. Loved the communication in the app even before boarding and while on plane from pilots.
