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 USB ports which are way outdated.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

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

I was not able to buy food in the flight. They refer to include your Credit card in the APP, and if you are not from USA (i have a credit card form Canada) it is not possible

Over two hours wait to get wheelchair assistance from arrival to the departure gate for LA was unreasonable even though there appreared to be heavy demand.

Airline did not explain reasons why flight was delayed two hours. Explanations were badly needed and rarely provided. Problem seemed to clearly be the airline’s fault and not the fault of the weather or airport.

I was delighted that we were able to get on the 4:40 pm flight rather than our original booking at 6:55 pm!! Other than that, the flight was comfortable and landed early😊

The flight and crew were fine. The entertainment- the sound was so bad through the headphones I could barely understand it and it was a show I had seen before. The food might have been fine but having to have an account with united in order to access the app in order to pay for the food was rage inducing. I had entered my credit card info at home and logged in as guest but that wouldn’t allow the “wallet” tab to open in the app. And then the wifi was so bad that it took about 45 minutes to fully log in and get all the info working at which time I missed the food. You shouldn’t have to give your address, email and phone number in order to get a hamburger.

The control panel for the seat back screen did not work at all after takeoff.
