This leg was much better, but we did have to have a 3 hour lay o er after coming from a very exhausting hiccup with our flight from BNA to Den

The Air hostess were very rude on my flight from Houston to Austin . Their regular communication itself felt a they are shouting at people.

Boarding was easy. The seats are small and fairly uncomfortable

The problem with the seat assignments is that there were a lot of rows in the front that were empty but my row at the back was full. Just not so pleasant.

No food or entertainment, just a quick 40 minute flight. A little bumpy due to Santa Ana winds but pilot has no control over that. Good flight and landing!

Good but I prefer choose your own seat. With the new assigned seats they should board from the back I see no advantage to this new boarding. Just like every other airline

Mediocre. Boarding is now unpleasant. The employees, once friendly and nice, are now regularly speaking sternly to passengers, badgering them to do things right so they can take off on time and gate check bags because they don't have enough overhead bin space. The pretzel snack was crushed flat and broken into even smaller pieces, which happens frequently lately. Drink service was suspended before they reached my row.

The charges were ridiculous for an hour flight and the turbulence was very scary.

3 hour delay. Had to change plans and was still delayed.

The flight crew was extremely rude and especially not helpful when our flight was delayed.

Had to buy a snack box as I am gluten free. They should be free in extra comfort. Food they provided was awful. Not enough water stops.

it was good except the too big men in my personal space.

Free WiFi was awesome. I hate the five hour delayed take off.. arrrgh!

Overall, we had a very good experience with Alaska Airlines on our flight from Honolulu to Seattle. The First Class cabin was comfortable, boarding was smooth, and the crew was friendly and attentive. The meal service was solid and the overall flight felt well organized. One thing that stood out negatively was the drink service. I was in First Class and, while quietly watching movies and not causing any issues, I was cut off after four drinks. I understand safety policies, but the cutoff felt a bit premature given the context.

Cancelled the flight cuz they sent the WRONG plane and then they promised to rebook us and let us know within the hour what our next flight was. I have heard nothing after 12 hours and can’t get ahold of anyone.

I paid for WiFi but it never really worked. That was frustrating.

I flew Hawaiian Airlines three times during my trip. Each time, when we went to baggage claim, it took about 45 minutes to an hour to receive our luggage.

The kiosk was fast. I got in and got my baggage tag right away. There was a long lines at baggaged check in But it moved fast and checked my baggage with no problem. The flight was good. The flight attendants were very helpful, friendly and always smiling.

We were very late to take off, late exit plane, and luggage took a long time.

Short trip from Honolulu to Kauai. Not a major issue. Only concern was the drop off of the luggage for departure. Only one person handling all of the passengers. She was busting her butt.

Omg the disaster at the security was on another level! “Go to this end, sorry closed now, go to that end”. Ridiculous! This took over an hour! As far as the airline was concerned although I booked nearly a year ago I couldn’t get my bag tag - stand in another 15 minute line or my seat on Hawaiian Airlines- 5 more minutes! Then my TSA status was denied. Like what the heck! Makes a person not want to travel with this amount of incompetence

The Honolulu Hub needs 2 to 3 times the amount of things to do as well as shuttles that transport to/from gates and terminals. Arriving from OCONUS locations; transferring to CONUS locations its a miserable experience. Fetching and re-checking bags, then returning to a gate across the airport take longer than any other large airport. If youre confused by what I mean, the process goes like this: Disembark plane Walk a mile to the main terminal Walk half a mile to baggage claim Wait 40 minutes for baggage Walk a mile to re-check-in baggage Wait 20 minutes for checking in those bags Fo back through the wrong TSA line because the signage is poor Almost miss the connecting flight because your gate is across the airport.

The crew were exceptionally nice and accommodating. My wife was tired after the flight from Haneda, Tokyo. They let her sleep and served her dinner later after she woke up, before we landed in PDX.

Horrible food and crew. Crew were laughing and talking loud while people were trying to sleep

I liked the Starlink WiFi but didn't like how they said they were the only airline to offer a free meal and it turns out to be just a standalone sandwich and then charge for snacks to go with it. Rather have the free snacks like Southwest, but have the option to purchase a decent meal for a 5+ hour flight.

Canceled my flight within 24 hours, causing me arriving home midnight. Will never book Hawaiian airlines anymore

I always love flying Hawaii and I have nothing to add

Flying with Hawaiian Airlines is a treat! They have the best crew, food and drinks! I’ve always enjoyed flying with Hawaiian Airlines and will continue to use them!

We decided to take our mom on vacation but we were worried how well she will do on the flight, she's a senior and required special accommodations such as transport chair since she can't stand for long periods. To our surprise my whole family was given priority boarding, my mom was given chair, we were not standing in line and were given seats in good area next to our mom. A+ experience!

Love you guys are so friendly and kind and wonderful

They told us yesterday APR21st that they were cleaning the plane and we got delayed. After that they said they didn't had any crew for the flight so they cancelled the flight till next day.

The crew was great. Very friendly and responsive. The plane was old, small and tight. We ran out of overhead space and I had to check. Middle seat was particularly tight.

The flight was delayed from take off because only one runway was operational in San Francisco.

Several missed and almost missed connections. It felt like everything was being patched together last minute without enough resources and it ended up being an extremely stressful experience that basically ruined our weekend on the west coast. What a waste.

Packed in plane small uncomfortable seats elbow to elbow nobody wants to be in that situation for the money they paid

Checking in united could not figure out my star alliance gold. Baggage did not get marked priority and didn't receive boarding passes. When got to SFO lounge personal fixed everything Immediately

Flight left on time, arrived early, pleasant staff provided water, coffee, etc. access to bathrooms was reasonable and were well maintained. blankets were available, lots of entertainment options. LUGGAGE SERVICE WAS GREAT. I got my one checked bag quickly and was able to make a bus connection for a 2 hour bus ride saving me from waiting another 1.5 hours.

Terrible, if possible won't be flying again anytime soon!

Wonderful in-seat entertainment with seatback screens and huge selection of quality movies. The ability to bluetooth connect headphones was amazing.

Overall, the flight was good. Lounge access should be with all business class tickets.
