Crew was outstanding. Flight was fine. Food was a joke! I didn't get the priority I paid for!! That pissed me off since I paid extra!!!

I liked the price of the 2 way tix. I hated having to pay $8.00 for Internet access. It should be free. Legroom and seats are very confining.

The one stewardess was rude about helping me put my bag in overhead….she said “ Is it heavy ?” (I am 73 yrs old)

The flight was about an hour late, and there was notable turbulence for a good part of it. But of course, that was not Alaska Air’s fault, and I think the crew did a good job of keeping it safe. Service suffered a little as a result (I wish I had been offered the option of purchasing food). Overall, it was ok, because we landed safe and sound. Thanks!

Flight was delayed 2 hours. Other than that, it was a good flight.

The flight was late getting in, so many were stressed. The snacks for a LONG flight was not enough.

The whole experience went very well except the rest rooms were a disaster

Sat on tarmac for 30 minutes despite staring at three empty gates, one of which we eventually pulled into

Everything was great. Flight was on time with no issues. It was a short connecting flight so ww didn't have food offered. The gate we got off at was very close to our connecting flight gate so that was very easy.

Pilot warned us it was going to be bumpy, which I usually like when it is, but it wasn't, so I spent most of the flight unnecessarily wondering when it was going to get rough. Just can't win sometimes. Ha!
