Unfortunately 4 hour 40 minute delay because of airport then one hour into flight diverted back to Kona elderly man on plane got heart attack trying to get home some how

Hawaiian Airlines, like most US-based ones, constantly provide sub-par service and pack their planes to the max with all kinds of last-minute-purchase schemes. As a result, it makes every flight so uncomfortable and generates high health risk for its passengers. In one word, GREED rules the day!

Terrible airport. It took over one hour to pass checkpoint and security gate. We stood under the sun in the long line

Reserved seats and yet did not get my original seat because someone else was seating in them and the crew member did not try to find out what was going on with the issue. My wife and I did get similar seats. This created concern and unnecessary issues.

All airlines seem to be a scam with having to pay force assignment, baggage fees, and completely garbage food. Our flight attendants now seem to have a power trip complex. It’s clear they know we have no other choice if we want to travel so they don’t care and let you know it.

Tickets we booked together in January became two different connecting flights. VERY PISSED a about this and a terrible start to our bucket list vacation

I needed more space to sleep on an overnight flight.

Very good; ohana atmosphere and taking care of customer care

Flight was delayed an hour, so that was inconvenient. But they tried to make it up in the air, which I appreciated. Crew was very nice, service was excellent. Description of food didn’t quite match what was served, but it was tasty. 👍🏽
