The plane was freezing. A few other customers mentioned how they can’t get their temperature right on their flights lately.

The plane was freezing. A few other customers mentioned how they can’t get their temperature right on their flights lately.

The food was fine, I was in economy so wasn’t expecting more. Would have liked an entree like pasta/lasagna. Entertainment/movies were ok. I have Apple TV & HBO so I was searching for new releases. But these are just my preferences for food & entertainment. The flight was good. I like the design of your seat backs/tray tables with the extra cup holder and screen holders

Flight was delayed 14 hours! We missed an entire day of our vacation and had to pay for hotel that we didn’t use

Could not check in online. Called airline twice, thinking Hawaiian Airlines could check me in during phone call. NO. In 2nd phone call, Customer Service explained that due to “transition period” of Hawaiian Airlines/Alaska Airlines merger, I could only check in at the airport. In addition, flight to Kahului was late at arrival gate; I made connection to Lihue but my bag did not, so I had to return to Lihue airport a couple hours after my arrival to retrieve the bag.

Flying on Hawaiian Airlines was good. But, getting a boarding pass was a hassle. I booked what I thought was an Alaska Airlines flight that was actually a Hawaiian Airlines flight. I couldn't check in online. I had to wait for the Hawaiian Airlines counter to open so I could get my boarding pass which was a requirement for me to get in The Club or the Centurion Lounge. (I had no check in luggage so I didn't expect to have to physically check in.) The Alaska Airlines staff blamed the FAA for the problem.

When we checked in our luggage, we had to use the tray, but include this tray is extra weight. I think you should not use the tray.

I flew from San Francisco to Honolulu on Alaska Airlines codeshare with Hawaiian Airlines, with a Hawaiian Airlines plane and crew. The flight was well organized, including boarding and deboarding. The crew was professional. Unfortunately, the charging ports at my seat and the seat next to me were broken. The Hawaiian airline terminal was a pleasant surprise compared to the rest of Honolulu airport.

Window seat and a packed plane. A very uncomfortable flight.

My flights went about as good as they could be. I’ll always take Alaska when possible.

The staff were great, no screens on the back of seats and the connection for the films on your own devices, was not great.

No charging outlets worked. Other than collecting trash attendants didn’t come around. No one could hear flight attendants announcements during the flight. Seat pads were horrible. Sitting on a board for 5 hours. What happened to Hawaiian airlines comfort, hospitality, and extras? Our pilots did an excellent job trying to minimize turbulence and incredible job in landing in windy conditions.

I could not believe that on a 5 hour plus flight we were not given a complimentary meal . That should be illegal. Or it would be nice to be informed beforehand that a complimentary meal would not be provided. The wording in the email I got about pre ordering food was phrased in a way that made the food seem like it would be free. Very misleading! Also during boarding we were informed there would be empty seats we could move to if we wanted, all we had to do was wait for an announcement, however an announcement was never made. Then when we tried to change seats ourselves we were singled out over the loud speaker and told we could not move without asking. Then the flight was about to take off , so we didn’t have time to ask . Then we were told we could not move to the exit row because you had to pay for those seats, but we were not told where we could move. Also no one was in the exit rows so , if something happened no one would be there to assist the passengers. Also people should be allowed to move there if the airline wasn’t able to sell them. One passenger asked if he could pay for the upgrade and the flight attendant said she did not have the capability to charge for the seat on her mobile device, so the airline ended up losing possible income anyways . So why not let people move there during flight if you have no way to charge them? Then the landing was bumpy and awful and many passengers complained out loud when we landed .

Most of the crew was wonderful but I had one bad experience with a crew member. When realizing my seat did not have an outlet compatible with my phone charger that I would need for transportation upon landing I asked an older, blonde heavily madeup member (I am describing her as I did not get her name) if there were chargers elsewhere I could use she said no, that not even the flight attendants had access to any. This however being my second flight of the day with Hawaiian airlines on a similar plane knew that chargers were available in extra comfort seating. I asked another passenger if I could use their plug and they agreed. She twice berated me for this and when I asked her to please stop talking to me about it she yelled that she was writing me up and ran down the aisle and did not return. I found this behavior disturbing. The other passenger was not bothered and this didn’t appear to be a safety hazard to anyone but it seemed to enrage her that used a plug that was not next to me.

They canceled our flight and reboot us for a later flight which threw off the rest of our plans

Friendly and helpful crew. But we departed 4 hours later than scheduled departure.

Wonderful flight. Food and drink were given as well as wifi. Amazing luxury!

They should have offered the headsets for sale so we could watch the entertainment. Our earbuds did not work. I thought they just did not have them. But then I called Hawaiian after and found out they were available for purchase

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

Our first experienced in Hawaiian Airlines was just okay. I traveled with my 2 year old and 5 year old and both kids are first time in Kona. We had delayed in San Francisco for 3 hours which is okay safety first. Originally our flight from sfo to maui to Kona since we had delayed the airlines re-route us from sfo to maui to Honolulu to Kona. I don’t know what to do I felt bad with my two kids they have been in 4 Airports and 4 airplanes going to Kona. I cried after we checked in at the courtyard Kona. It was a lot for my 2 year old and 5 year. Like I said I know it is safety first but the Airlines could have done better for people that traveling with kids. If you are in my shoes all what will you do? Anyhow, I tried to make my two kids as happy as possible while we are in Kona. I am not certain to fly Hawaiian Airlines again. I hope my experienced helps to improve whatever it needs to improve With all due respect, Christina Lorenzo

In flight breakfast sandwich unexpected, no charge and very good. Economical ticket price. All good.

It was a short, comfortable flight. It did leave an hour late due to the pilot having to be replaced (family emergency) but that didn’t inconvenience myself & my friend. The situation was explained, eventually.

Lost one piece of luggage even though I checked in 2.5 hours before the flight

Horrifying Almost 2 million miles. Bring your own food and drink. One coffee or drink every three hours. Have to order meals on app more than 24 hours ahead Tiny and dirty bathrooms

Older aircraft, no meal, only food was for purchase. Not impressed United.

Stuck on tarmac for two hours plus a 5.5 hour flight. Rude flight attendant. And no meals, not even for purchase!

I learned that seating towards the end of plane that a line forms for the restroom and people use your chair as a hand railing, bumping your seat consistently. I was seated in the aisle. I think that next time if I am towards the back row I would want to sit in the middle or window seat.

Boarding seemed to be organized bedlam. For what ever reason, preboarding took longer than 20 minutes. Made the plane 20 minutes late taking off. Luckily we arrived on time. Flight crew seemed very friendly. Only slight turbulence.

The personnel were professional and friendly. The Boeing 737 Max 9 is too claustrophobic and was very warm at both airport gates, and still warm in the air.

Everything was great, only problem was that flights were delayed

Crew was nice and helped. But they placed my checkin suitcase on the wrong airplane so I didn’t have my CPAP machine to use for 1 night. The United attendant at HNL informed me that it’s on the next flight from SFO to HNL and ETA is 8:18PM and that they will deliver it tonight. At 9:30 PM, I saw conflicting reports , one saying it’s on the way from the airport and the other saying it’ll be delivered after 6:45 am tomorrow. So I called UA Zbaggage Resolution Center and the agent says it’ll be delivered tomorrow by nighttime At latest.
