We moved from the international terminal to a new location. I think there are still some bugs to work out . We didn’t receive check in notification and had to scramble to find it but i think it will work out

We moved from the international terminal to a new location. I think there are still some bugs to work out . We didn’t receive check in notification and had to scramble to find it but i think it will work out

Not so good. The takeoff was aborted after reaching 100 knots due to a problem with the front tires. I do commend the pilot for a quick decision and preventing a potential disaster. We returned to the gate to put fresh tires on the front. Our flight was delayed for over 3 hours. The rest of the flight was okay. We were reimbursed by Hawaiian Airlines for only $50. Not too generous

Arrived at the gate with no seats assigned. Was told by gate agent the flight was full and we would not be on it. I asked the gate agent how could I be sold tickets when the flight was full. She replied, “Thats just how they do it.” I was able to get seats once I arrived at the gate. The flight itself was great. I’ll never purchase tickets without seat assignments from kayak or anyone again. Shame on kayak or Hawaiian airlines or all of you.

A cold sandwich would be much better than the warm gummy croissant.

Liked the crew. Seats were uncomfortable during the last few hours of the 11 hour flight. Better selection of movies .

They cancelled our flight and one after and then crammed everyone on a late flight. Refused to give us a meal voucher because the delay was less than 3 hours. In the end the delay was 4 hours. No reason was ever given for the cancelled flights. Fly Southwest!

The temperature on the plane was too cold and the food was not very good. Everything else was good.

There was mention of a complimentary magazine but none were in the seat pockets. The flight is short so understandable not having food or a snack.

Flight delayed. Then left much later than new time. 88 year old dad waiting at Kona airport for ages.

This is my first time flying Hawaiian. It was so disorganized and poorly coordinated, resulting in the most unacceptable delay
