Wonderful respectful staff for a short flight late at night...lots of considerations all met!

Flight was delayed which led to missed connection, but rebooked on a more direct flight at the last minute and arrived in Juneau on time with all our luggage. Little stressful and our family seating got split, but it all worked out in the end.

Only issue was the 2 hr delay after an 8 hr layover. Very long day.

Very bad, terrible food and late by 2 hours. Then no to open aircraft doors

Flying on Hawaiian Airlines was good. But, getting a boarding pass was a hassle. I booked what I thought was an Alaska Airlines flight that was actually a Hawaiian Airlines flight. I couldn't check in online. I had to wait for the Hawaiian Airlines counter to open so I could get my boarding pass which was a requirement for me to get in The Club or the Centurion Lounge. (I had no check in luggage so I didn't expect to have to physically check in.) The Alaska Airlines staff blamed the FAA for the problem.

Terrible check in experience, and they ended up losing our bag.

they didn't fix a plane and we were delayed travelling an extra 12 hours.

This flight was how a flight should be. The flight from Hawaii to Seattle was terrible

Our big luggage never made it to Boston. Very crucial to get it ASAP as heart medication is in there.

Wish I got An email stating that I needed to check in at hawaiian even if I made my ticket thru alaska. I had to walk to terminal A from Terminal B.
