Missoula is a great airport. Desk and gate crews were very helpful and friendly

They changed the flight time from 4:00 to 1:50. We missed the flight because we did not know. We were not entitled to any sort of refund.

Honestly the bathroom cabinet under sink fell out and was completely broken. The floor or walkway was worn out and it smelled wierd. But the seats were terrible for comfort. I truly hope that my trip home in February is better.

Hadn't flown for a while the crew was wonderful! Trip was great. My only challenge is navigating the airports. Getting from one plane to the next! All on all nice trip!

Good but a boarding pass for my return flight was not sent to me.

The crew was very friendly, it was nice that my gate was not changed at the last minute.

Flying from Bzn to Sea was a pain. Almost an hour late leaving, close to missing connector.

Late out of Kalespel missed flight to LAX as the plane backed out. The same thing happened leaving LAX headed to Seattle. Connection terrible, finally arrived at Seattle (different concourse but the plane had left on time but again as we watched it leave. NO curtesy for passengers changing planes who hustled to get there. An 81 and 71 year olds in good shape. Alaska was pitiful, and OFF our radar. Never again. Please send to Alaska Air Lines. TERRIBLE.

I had a emergency and was u able to take the trip and lost all my money cause they wouldn’t refund my money.

First time travel by myself. Everyone was so helpful and kind. I recommend Alaska Airlines for everyone.

Yall need to integrate your system with Alaska more efficiently. They booted me off the first flight because of a discrepancy on your end.

Unfortunately, I was put into the middle seat in the first row of premium seating. Sounds nice right? No! that is the worst seat in the plane. I wish I was in economy rather than be in that seat! There is no seat back pocket, no tray table, no charger. Nothing! so unless you're row mates are willing to let you share their basic amenities any flyer should have, you are stuck. It was the worst experience ever! And the flight attendant forgot to take my drink order. I felt like the forgotten flyer.

Delayed and cancelled flights were hard and very stressful, both ways!

The flight was CANCELED!!! Can’t get much more “poor” than that. I had to switch to American Airlines, add another layover and got home in Honolulu 4 hours later than I was supposed to be home. One bright spot was Josh with Alaska Airlines at SFO. He got me on a United Flight that got me home a few hours before I would have. Without him I would have gotten home almost 7 hours after my originally scheduled flight.

Canceled my flight within 24 hours, causing me arriving home midnight. Will never book Hawaiian airlines anymore

The entire crew had everything handled and truly worked together. More than once, I saw them hustle down the aisle and back just to serve customers.

The flight was great. But the problem is we actually booked a flight with Hawaiian Airlines. We even received a Hawaiian Airlines confirmation number. So this made it really difficult to check in the online. So I had to call Hawaiian Airlines to get our Alaskan Airlines confirmation code to check in. Also weren’t told we were flying on Alaskan, but once we got on the plane, everything went well!

Agents talk too fast over intercom. I know it’s memorized and we’ve all heard it before. Just slow down a little. Stop charging for checked bags. I was pleased to get my bags promptly at each end of my flight.

It was clean and the crew was great. I wish the chairs could recline just a little more and you would provide small pillows for people with bad backs. My back is fused and a little support would be great.

I was on Alaska and its backup airline. I was scheduled for wheelchair service but ON ONE SHOWED UP. When I asked, desk attendant said they didn’t have any.
