Everything from the time I booked my flight through to the end when I got home was smooth and wonderful. Service was great, the flight attendants were attentive and there were no outstanding delays.

Delayed and no entertainment? I also forgot my headphones and immediately reported it and have not heard back yet.

The crew was very friendly. Boarding was quick and efficient.

You need categories to note when food and entertainment are not available. Alaska's system would not update flight info on the board for this flight, so there was some confusion after deplaning from the previous flight as to which gate and depart time were accurate for this flight.

we waited for 50 minutes to check a bag and missed a flight. do better.

The flight crew was very professional and pleasant. Our flight was delayed 3 hours, but Kayak informed me in advance

Before I even boarded this old white man , a fat Samoan lady, and a short brown guy were at the desk. They asked if we could have 15 volunteers to get free checked bags cause it was a full flight. I waited in line, I got up to the short brown guy and he asked for my boarding pass and I showed him, he said that he can’t check my bag because I wasn’t given a seat yet. So he had me go to the next line with the old white guy, but before I switched lines I asked him, well if I go to that line, will I be able to check my bag so I waited in line and he said yeah, it doesn’t matter , I’m good. So I switch lines and wait in the line of the old white man, with every guest before me he was very sweet , making small talk, smiling and had great eye contact( all of the people he was talking to was white) I come up and he doesn’t look at me , then says I’ll be right with you, I wait for him to initiate and when he does he’s like what’s up? I was like the man next to you told me I needed to get checked in before I can check my bag. He’s like what’s your last name and I say Valenzuela , and he said we’re not there yet, all while not smiling, no eye contact like he was with the other guests. He said we’re will call you when I get to you. So I go sit down and I’m sitting down for less than a minute and he calls me and someone else. I go up and say Valenzuela and he’s like who are you and I’m like Valenzuela , he’s like hmm and says don’t go anywhere and calls someone else. I finally get my seat and I go back to the short brown man and ask if I can check my bag and he said there isn’t any room available and I was like? Wait you told me and then the fat Samoan lady said yeah we don’t need anymore bags thank you. I was dumbfounded and just walked away. So rude. Terrible experience and terrible communication on their end.

The flight was delayed, but once it arrived everything moved right along.

Coke zero offered...good. The proptness of flight was late. This has been a everytime thing for my last 9 flights. And is putting alot of pressure on my connecting flights. Not a bit punctual. I am always early, but Ak. Airlines is not. And people i happen fly beside, parrot the same thing. The baggage delivery to baggage claim, is not prompt. Its slowwwww. The seats are poorly padded, very crowd. We need more room, not padding the airlines bottom line. Its like a cattle car. More leg room, more side to side room. And attendants need upgrade of verbal skills. I have been faithful to Ak. A., but it will change if changes are not made. Not the only planes in the sky.

Everything was great except for one piece of our luggage was severely damaged and crushed. There were no agents available at baggage claim and the hold time on the phone was over 3 hours. So therefore we were unable to file a complaint. We will be speaking to Alaska Airlines about replacing our luggage when we check in for our return flight.

All good except once again bags took an hour at Midway Airport Happens all the time. Ridiculous

Everything went smoothly and we even arrived a little bit early.

Great vacation. Can't wait till next year for another one.

Great flight but super high price. Glad it was a business trip and not personal

On time. Friendly staff. Took to long to pre bord all the specialty groups. Cramped small plane

The seats were comfortable, and the boarding process was pretty smooth.

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

The staff was very friendly, professional, and courteous. The overall flight was a great experience.

The crew canceled the complementary snack and drink in anticipation of turbulence that never materialized. I was counting on the drink (water) to take the the doses of medication - prescribed for my heart condition - that were due during the flight. Since no snack or meal was served on this flight, I cannot rate the food quality. Otherwise, this flight was excellent.

Departure was delayed more than 1/2 hour while we waited for luggage (only) transfer from another flight/plane. Once approved for takeoff, the flight was excellent.

The crew at Hawaiian Airlines was fantastic. Kind and hard working. The pilots were great with giving us all the updates to make sure we were informed.

Very good. Nice plane and we sat in economy plus - bigger seats, more room. They served a meal and snacks, and the meal was an apple stuffed pancake that was very good! The snack for us was a hummus sandwich - also very good. The flight attendants were helpful and nice. They have plenty of movies and shows to watch. My only negative -- they changed our flights around and did not adjust the layovers, so we ended up with a very long and unnecessary layover in Honolulu.

Flight scheduled to take off at 5.55pm but it did not take off until 7pm due to some food delivery delay.

The crew was quite good, they came by often with drinks or to collect trash. But what wasn't nice was the flight was over weigh and several people had to be rebooked. I was questioned whether I should have a seat when I was getting to it. The in-flight entertainment kept buffering and interrupting. And the route took the airplane through high winds which caused us a longer flight

Wasn’t on the flight due to Alaska cancellation…also after all the rerouting, I was going to be on a later flight that left SFO at 7:47pm, which meant an almost 6 hour layover. That same Hawaiian flight was delayed for another 2hours.

I always love flying Hawaii and I have nothing to add

Everything was great and smooth. Given the short flight there was no entertainment but the rating does not give this option. My first flight with Hawaiian was a success all around.

comfortable but the food is horrible. I have flown Hawaiian several times now and no matter what they say the food is its the same squashed bread with melted goop inside. Tastes fake and isnt what they represent, its quite nasty. What happend to real food? And there is NO entertainment!! so not sure why they are asking for a review on that.

I was very, very cold and a stranger loaned me her sweater next to me. I didn’t wanna buy a blanket just for a four hour trip when I did not need the pillow or the earphones. I don’t mind purchasing a blanket, but I only needed that not all of it accessories. Cold air pretty much blew the entire trip. Two people in front of me both bought the blanket packages. Maybe that’s the idea. The crew was exceptionally nice and passed through multiple times.. the restrooms were very clean and usually accessible.

3 hour wait on customer service after flight was cancelled. Was bumped to a flight where I wouldnt have gotten to my destination for another 2 days. Had to fully refund flight and book a new one the following morning. Paid twice the amount for the flight than I had originally booked. Very disappointed I was not offered any sort of discount or points for all of the frustration, in fact the airline profited twice as much off of me by cancelling my flight and and changing my entire trip.
