The seats were comfortable, the overhead bins were ample, the staff was helpful, attentive, and friendly. I enjoyed free texting. However, I much prefer Southwest no reserved seats (take any unoccupied seat) and their policy of two checked bags free, and ability to freely change flights. The Alaska airplane was nicer and newer than the Southwest one. Overall, my Alaska Airlines flying experience was a very positive one.

The seats were comfortable, the overhead bins were ample, the staff was helpful, attentive, and friendly. I enjoyed free texting. However, I much prefer Southwest no reserved seats (take any unoccupied seat) and their policy of two checked bags free, and ability to freely change flights. The Alaska airplane was nicer and newer than the Southwest one. Overall, my Alaska Airlines flying experience was a very positive one.

We boarded the flight just fine. After an hour of not moving people started asking what was going on. Finally after 1 hr and 40 minutes of being in this plane which was no longer fresh but hot due to all the bodies and the 114 degrees outside. They decided to open the door back up and asked whom ever wanted to deplane could and we would be boarding 15 minutes after. That did not happen. Was over a 3 hr delay and had to run to work it connecting flight once we landed in Seattle.

The flight was delayed by more than 2 hours which delayed all our plans.

Flying isn’t always fun but my flight was good and that’s saying alot

This is where things were a bit upsetting first the wheelchair assistance person not only was playing games at first leaving us to wonder. When I did get another person to help she took me to the gate the Alaska Airlines person Alex was rude. I didn't have a seat assigned which was not helping my travel anxiety, he honestly didn't seem to care when he step away I came to another agent named John who was very empathetic and kind. He looked in his computer and gave me a seat realizing my situation.

Friendly staff on the ground and in the air. On time performance. Comfortable seats and friendly flight attendants.

Everything was good except the flight out of Pasco was delayed so long we almost missed our connection in Seattle - had to literally run from one gate to the next!

No leg room but flight is smooth flying. Pretzels really?

The pilots were great. Service was good. Wish I had more room in the seating area because I was seated next to the only other large person. He took up a little of my seat as well. Very nice man. Wish the crew could have done a small shuffle to make it better for both of us. Still, it was a good trip both ways. Thank you

I didn’t know that food needed to be ordered ahead. Please include this in the reservation information. Overall, very good experience.
