Big delay of over 7 hours on next leg of trip with Alaska. Would have been nice to have food or something

We were late so that was what was worst part

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.

Great, overall. Thicker seat cushion would be nice. My butt hurt the whole flight.

Thicker seat cushion would be nice. My butt hurt the whole flight.

All good! No entertainment on this new plane yet but ok for this short flight. Great on time flight! Thanks

No non-alcoholic drinks available except water and small apple juice cans.

The flight was delayed over two and a half hours thus causing me to miss my best friend’s funeral. All because the flight crew had to get more rest. That was the reason stated. I understand however very unfortunate. Glad everyone is well rested and resting in peace.

All good except both the outbound and return flights were delayed about 1 1/2 hrs.

Not great. My flight was canceled due to a mechanical problem and I could not get rebooked for the same day. I needed to get to my destination yesterday, not today. I was able to book with another airline but it was a layover and ultimately a 1 hour flight took me 12 hours. Normally I like Alaska much more than Southwest, but Southwest came through with a not terrible price for same day.
