8.0 Very good

Aaron, Nov 2025

I purchased a 1st class ticket and unfortunately the main flight attendant was not the best and seemed more interested in her phone than the passengers at times. Then the plane didn’t get restocked and the only snacks for this flight were pretzels. However I would like to say that the rest of the flight crew and ground crew at the airport we’re great, especially the people that wheeled me around the airport some and then the one getting me to the plane and the automated wheelchair that wheeled me through the airport.

The small ej plane didn’t have any entertainment aside from the stuff on the Alaska website that has to be accessed from your own device. But everything else was just great.

Great, our stewardess, Christina, was wonderful.

2.0 Poor

Anonymous, Nov 2025

Last-minute flight delay in originating flight caused me to miss connection in Seattle by 10 minutes....leading to a 7-hour wait. Communication was poor. Boarding: your staff really need to do a better job of making sure that passengers board with their assigned group. I was in group C, and most of us were waiting but people just kept walking into the line, with the result that all the bin space was taken. You should check boarding group with each passenger and if they are trying to cut in early, tell them to wait.

2.0 Poor

Gaston, Nov 2025

Flight from PSP delayed ~2hs and missed connection. Terrible service providing acommodations & food (no rides - just the hotel van every 30 min, which you have to call). 12 dollars in food for a 9 hour delay. 30+ minutes to get everything sorted out.

Good, but because I fly internationally I found the food and service lousy compared to European standards. You should include a regular small mean (and not a lousy sandwich) and ear phones. People who travel from Europe are not aware of limited services.

Fine. But given how empty the flight was, I do not understand why my dog, in its carrier, could not be placed on the seat next to me (which was empty) rather than on the floor under seat. This seemed like overkill on the rule following by the flight staff.
