The flight was great! The flight attendants were friendly and attentive. I would definitely fly Hawaiian Aurlines again!

You have to buy the ear buds and they only offers little cup of water twice.

Flight was on time, crew was friendly and prompt with the service. The only thing that could be improved is the seat space, but that's wishful thinking

Hawaiian treats you right. They give you a little comfort pack. To watch movies or sleep. Earplugs and eye shields. I will definitely recommend and also fly with them again.

Cons: Rode a newer Airbus - had the same rattle in the panels above my seat (plastics not secure b/t lighting and panels) as the last Airbus I rode. Cabin was quite warm, borderline hot. Asked to pay for headphones. And the reason I am writing this - when we arrived it took over 20 minutes to get our door open due to nobody on the ground ready for arrival. Likes: Staff was friendly, helpful, and professional. Sandwich was quite good.

Service, cleanliness, comfort, and food were all wonderful. Hands down to JAL.

The worst flight experience I've ever had. Our flight was delayed 14 whole hours because the flight crew never showed up. We had to wait in a two hour line to get our new boarding passes, we were told we had no other option but to fly at 10pm (we didn't depart until 11:45pm). Everyone had to contact their hotels and car rental places, workplaces, etc. since we lost an entire day's worth of travel. The crew showed up at 10:15, which was past the time we were supposed to board. They were laughing and being completely smug when they boarded, and they took another hour to board us onto our flight. The flight crew never came to check in on us, we were quickly given one drink and sandwich and they turned off the lights and were negligent the rest of the trip. My mom asked three attendants for a seat belt extender, they never brought one. I was dehydrated and never received another drink. They were very rude and unfriendly, we had been up since 4am the morning of our flight and didn't land in our destination until 2am the next day (5am local time). This was unacceptable service and treatment, these flights are not cheap and we were inconvenienced out of an entire day of travel. This was 100% avoidable and was the fault of Hawaiian Airlines, and their crews inability to show up to work on time.

Loved the leg room, usb charging, outlet, food, staff. The seats were very uncomfortable for some reason and made my buttocks ache and would have liked to be seated together from the time of purchasing tickets without having to pay extra.

Usually we have a pleasant trip on HA. Not this time! All stewards were unpleasant, rude, rushed, condescending. First step onto the plane, WE greeted the crew with an “Hello!”. They greeted us with a terse smile then ignored us. Not a good start. Even over the PA announcements, they were rushed and unpleasant. One Stewart even berated a passenger in front of us when all they asked is if the purchase cart had vodka to purchase. The steward said “LIKE WE SAID OVER THE PA, THIS ONLY HAS FOOD OR BEVERAGE!” Vodka is a beverage! It was a legitimate question. Not sure why she treated the passenger this way. Taking trash was even unpleasant, No “Thank you” or at least a smile. I work in CS. I know good CS can make or break your trip. There was absolutely no “aloha” on this trip. All clearly did not want to be on this plane and felt strongly that they did not want to provide a premium service to their clients. This might be our last HA and cancellation of my HA-MC if we are treated the same way going home. We are typically treated with kindness and warmth in the past with HA. This trip was unacceptable.

Overall it was a good flight, but the food should be looked at. No options. The seat was also uncomfortable and very tight.
