They changed our flight to Kalispel and we ended up getting there close to midnight. The return flight got changed as well by a few hours. Then of course some issues with the plane and we were even later. First time flying Alaska, may be my last.

They changed our flight to Kalispel and we ended up getting there close to midnight. The return flight got changed as well by a few hours. Then of course some issues with the plane and we were even later. First time flying Alaska, may be my last.

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

The flight was delayed out of BIL so many times that I was not able to make my connection. I was rebooked for the next day, losing a full day of my trip. I still have not been compensated as promised.

2 hour delay. Then some luggage was unloaded at 1baggage claim #7 then without notice the baggage claim was changed to #12. No one informed the passengers they were changing baggage claim turnstile. Several of us waited for 90 minutes after the 1st turnstile stopped and changed to other flights luggage.

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.

Easy check-in. Good customer service. Had to check carry-on due to lack of overhead space. Wish the airplane was configured with more overhead area so this doesn't usually happen.

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.

We sat on the tarmac for so long when we got to SeaTac that half the plane missed their connections.

Poor, no one with Alaska Airlines is in a hurry to do anything. Slow, lack of intent, inconsistent.

The flight ran out of snacks before any was offered to me. Otherwise the flight was good.
