Food and roominess were better on other international flights I’ve been on.

Food and roominess were better on other international flights I’ve been on.

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

The flight was cold. The entire time, the food was nothing more than a cheese hot pocket. They wanted to sell everything else midway during the flight. They said that we were landing in a half hour and then added that we had to return to Honolulu, but gave no reason why. I was so scared I was crying. I didn’t know until we landed that it was because of an unruly passenger that we had to turn around. The crew was very cold about it, and we had to wait in the airport where they gave us snacks, which was nothing more than a bag of pretzels and a fruit juice

It was great with the exception of a rude desk member on the way back. And a terrible sandwich on the way back.

One of the best flights Ive had in a long time

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

My flight was canceled minutes before boarding started. It took three hours to get rebooked and it was on another airline overnight with another stop added. All I got was two $15 food coupons.

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.
