When I got into Maui I had a layover but there was a flight to Honolulu earlier. I asked the gate agent to see if I could get on the earlier flight to get home sooner. Ke'van is so great! He was very helpful and friendly and I appreciate him very much

When I got into Maui I had a layover but there was a flight to Honolulu earlier. I asked the gate agent to see if I could get on the earlier flight to get home sooner. Ke'van is so great! He was very helpful and friendly and I appreciate him very much

This flight was delayed approximately 4 hours due to bad weather in HNL.

Flight delayed then cancelled then gate changed two times then baggage lost.

The plane is extremely loud and there’s no place to charge devices.

Not great to be very honest. Our flight was delayed after we sat at the airport until 15 minutes after we were supposed to leave . We were then notified the plane was being worked on “and the parts were out in the ground and still not finished .” Even though the work started the evening before and they knew it wasn’t fixed. . Then we were told it would be a 1:15 pm boarding time so we waited then at 1:45pm we were told it would be an 11:15pm boarding . It was changed to and 3:55am boarding the next morning . We lost out on a day in Hawaii and a night of our VRBO rental.

Safety record impeccable and important since flying many hours and thousands of miles over ocean.

Love the food service and attentiveness of the crew. Could have wi-if on flight

Seats on second leg from Hawaii to Tokyo would not recline. 9 hrs is long in total upright position.

Apparently the computer systems were down, so I wasn’t able to check in 24 hours in advance, despite multiple times on the app, the website, and by calling. Then I arrived at the airport and wasn’t assigned a seat right away. I had to wait until I was at the gate and waited about another hour for an agent. She was nice to give me a “free upgrade.“.

The crew worked to help us find standby seats and we were able to arrive at our destination early which was great. Only drawback is airport at Kona which is in need of update - waiting at gate passengers exposed to jet fumes, there’s only one restaurant with minimal choices, etc
