Interline connection was terrible. Boarding pass from American didn’t work even though it was valid. Gate agent not present to straighten out the mess until the next to the last boarding group was called.

It was great, I just wish the seats were more comfortable

Talk about boarding with ALOHA. The attendants at the counter and the flight crew were so cheerful and happy, it was good to go home with that little bit of friendly aloha I seem to not get on other flights. I have not flown Hawaiian Airlines for quite some time, but this was better than most of my flights back to the islands. I loved the comfortable seats, the updated videos that were so culturally integrated with necessary information. For example, how many times do you have to watch a flight attendant give the same ol spiel on how to use your seat buckle. Instead their modern video of actual flight attendants on a beach talking about how you should you operate your buckle. Or how about the kane dancing hula in the loi'i patches and talking about where the exits are on the plane. It was fantastic and entertaining. I also liked the fact that I was offered a breakfast sandwich that was quite tasty. Nowadays you have to spend $10 on anything inflight and it just gets so ridiculous with prices it was nice not to have to pay for a snack. I also liked the fact that for a nice sugar rush, Honolulu Cookie Company cookies were given. How is that for advertising? Love, love, and loved it even more. As a local I sure felt the spirit of Aloha on this trip coming home and I would never say no to flying Hawaiian Airlines again.

This was my first flight on Alaska Airlines and will probably be my last. I was in group F and was seated in the very last row against the bulkhead, and so could not recline my seat for the duration of the trip. I am 88 years old and as a result I deplaned with with a very painful stiff neck and upper back.

Everything was very good. Alaska Air can’t help the airport delay

The steward on my flight went above and beyond in hospitality. So friendly and helpful. If I could give him more stars I would. I was so impressed I plan to use Alaska whenever possible and will praise highly to family and friends. (Ive already told my daughter and I’n-laws)

Overall good. Good communication from the captain on delay, cozy seats, nice staff, and a perfect landing.

The plane was clean. The flight crew was friendly and helpful. The flight was smooth and the pilots kept everyone informed of our status, etc. It was my first flight on Alaska Airlines and it was great. I'll be choosing them again in the future.

Good but a boarding pass for my return flight was not sent to me.

I really wish there were TV monitors. I don’t have a mastery of computers, so I was left with a six hour flight, and no entertainment.
