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

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

My tray was broken and instead of being moved I was provided blue tape.

Terrible. Unfriendly, couldn’t care less crew. Left lights on entire time for 10 hour flight Departed at 5pm local time. Captain made one announcement entire time. No information given and clearly not interested in letting anyone sleep with lights up. Food served was poor. Entertainment was poor. No WiFi choices on screen backs was dated and cheap. Seats and amenities were dated and barren. Hawaiian used to get by on their service/aloha, but that’s been out the window. Even for local interisland I fly only southwest as they are far superior. Very disappoint in Hawaiian and this flight.

One hour delay. No Wi-Fi. Old aircraft. Nasty food

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

Increased effort to keep family members (purchasing multiple tickets in the same transaction) sitting together. Additionally, when faced with choosing seats at the automated check-in kiosk, only exit row seats charging an additional $9 were available, but if you decline to choose seats, it picks seats that are NOT exit row. How does that work, Hawaiian?

It was wonderful. I have never flown Hawaiian Airlines, but I would definitely do it again. They were wonderful.

Zero leg room. No entertainment screen. USB ports which are way outdated. The plane landed and stopped in the domestic terminal and we had to go to the international terminal to find our luggage.

I finished with my medical appointment early on Oahu and the Hawaiian airlines staff helped me get an earlier flight back to the big island. It was a great experience. There was no food or entertainment that is why I gave it a good

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

Do not like the feeling of being in the basic economy. Everyone should feel good no matter what.

Our original business class flight was cancelled so we not only downgraded but we were also spread out across the plane not sitting together in separate middle seats. My poor kids were scared and couldn’t see me on the flight and the crew wasn’t sensitive to the situation and what the airlines did to us. Very dissatisfied with United airlines.

The WiFi didn’t work and the seats are too close together. Very uncomfortable.

So so. Terrible aircraft choice for that leg of the flight.

delay several times and wait extra long to board. no entertainment service because there are problem for some rows. always encounter some delays for the last flight of the day.

On time every leg of the journey and exceptional staff at counter, gate, and on board. I haven’t travelled in US for a long time and was genuinely surprised how pleasant this was.

This was a Lufthansa flight. Disappointing main meal. Very rough over Canada and arrival at FRA. IFE was almost unusable.

Too many fees (but that seems to apply to all airlines nowadays)

For a 22 minute flight all you expect is for it to be safe and comfortable
