Tickets we booked together in January became two different connecting flights. VERY PISSED a about this and a terrible start to our bucket list vacation

Could not check in online - had to get boarding passes at the ticket counter and our daughter got bumped off our connecting flight. NOT OK!

I needed more space to sleep on an overnight flight.

Our flight time was drastically changed which caused us to lose a day of vacation

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.
