Room is great! Excellent value. Boarding & service extremely good. Food was the worst I’ve ever had on a plane.

Room is great! Excellent value. Boarding & service extremely good. Food was the worst I’ve ever had on a plane.

They lost my bag and 24 hours later have yet to find it

3 of the 4 legs of our trip the crews were awesome! 1 leg the trip attendants were rude & dismissive, didn't even greet us when boarding even though both myself & my husband said hello directly to them when we boarded.

There was an issue with the plane and it was late getting in. This caused me to miss my connecting flight from PDX to BOI. I had to ask if they would provide me with a food voucher and they did but didn’t seem to concerned about my delay.

I didn’t go, and can’t use a no refundable ticket.

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.

The staff was so kind and friendly! Boarding was efficient and communication was timely. I would seek out flying with Alaska Airlines in the future.

They closed boarding too early. They made me pay extra to continue flying with them. Their customer service is non-responsive. I used to love Alaska Airlines, but they've definitely regressed.

The vibe and energy of the Alaska staff on ground in Redmond is some of the best we’ve seen!

It was a good flight, short so there was no food or water service
