Would like to see more consideration of older people. I have issues with being on my feet and walking too far. You put me in the last seat on the plane. Way in the back. Other than that everything was vey good.

Would like to see more consideration of older people. I have issues with being on my feet and walking too far. You put me in the last seat on the plane. Way in the back. Other than that everything was vey good.

Portland reservationist required me to check bag… tho always been ok as carryon before this experience. She didn’t ask my name or destination, seat number; only looked at boarding pass. She then sent my bag to wrong destination: Idaho Falls instead of Bzn, Mt. I spent 1 hr in Bzn trying to get this straightened out and locating where my bag might be? The Bozeman customer service was great and figured out the error that occurred in Seattle. They were wonderful, filed a claim and located my bag. They also offered me compensation for my problem which was helpful. Missed my meds last nite and following morning. Hope this will be resolved later today. 🙁

The app is very bugy, did not work well. Other than that it was ok.

Excellent gate to gate delivery by wheelchair staff. Really appreciate it!

The flight was delayed an hour and it was not disclosed to the passengers until it was time to board. There was no in-flight WiFI available and such poor communication overall. Unfortunate that I was going to miss my connecting flight with poor communication on alternatives.

My flight was cancelled last minute with zero acceptable options and reimbursement. I called Alaska and was told I had to pay for my own flight home so I bought a ticket for $500, I missed work worth $450. I had no babysitter for my child and her father missed work for another $480. I have diabetes and health conditions that require medication and proper diet which was extremely difficult with only $48 of vouchers and not enough medication for the extra 24 hour to 48 hour delays home. I understand things happen but the support Alaska gave wasn’t responsive enough to compensate or reimburse for the inconvenience. It took several hours to get a hotel for the night as Alaskas link was incorrect, vouchers were used and had no more rooms, people were walking the airport 10x to be told their next flights weren’t accurate home. If someone was disabled I don’t know how they even got support.

I liked The generous baggage allowance. I did not like No meals onboard.

The crew forced all group F passengers to check bags because they said there wasn't enough overhead space, but when we boarded there was TONS of space. I was pretty annoyed by that.

Flight was delayed because overhead bin didn’t close. The most insanely stupid thing I’ve ever heard.

I didn’t make it because Alaska schedule my flight too tight, I had to run to the other side of the airport, and no one helped me get off the plane early or held the plane for me… so I missed it and it was Alaskas bad, not mine
