The agents were super helpful. I was traveling with my mother inlaw who needed whell chair assisstance. The help and accomodation from the checkin crew, to the boarding crew and inflight crew was excellent.

The food was terrible, worse that what you get with UA, an already one of the lowest standards to beat. How cheap one could be, providing that kind of junk food in first class. Unbelievable! The seats were not very comfortable either. And there were no screens either, not that I cared much but for you to know.

The aircraft was extremely warm the entire flight. After we landed we were stuck on the plane for another 45 minutes without a gate to deboard from. The smell of exhaust from the engines in the cabin along with the heat inside the cabin made the flight uncomfortable.

We appreciated that the flight attendant came through 3 times with drinks or water on the long flight..I was also glad that they were separating out recycling! I would have liked a 12oz sofa can instead of 7oz, but that's a minor quibble. The knee space in economy was also better than most of Alaska's competitors.

I liked the free snacks and drink. I liked the onboard entertainment. I did not like the WiFi cutting out in middle of my movie.

Same crew flew with us from Palm Springs to Bellingham, so they were great! Friendly and kind from start to finish. Great experience!

The flight was delayed and then it was very short. The crew was nice. The seats weren't as comfortable on this particular craft.

Excellent flight and on time. Will fly with Alaska again in future

I didn’t make it because Alaska schedule my flight too tight, I had to run to the other side of the airport, and no one helped me get off the plane early or held the plane for me… so I missed it and it was Alaskas bad, not mine

Flight was too short to have food or entertainment. Also, we sat on the tarmac for 30 mins waiting to take off. Busy time of day!
