The flight attendant and first class were very friendly, efficient, and wanted to make sure that service was great. Highly recommend this airline.

The crew seem untrained and uncertain no one ever checked up on us in our first class cabin. I had to ask for water four times and the lady kept saying she was busy when they weren't really doing anything. Had to walk to the back of the plane to get water for myself. Crew seem new and unexperience. You can tell this by the fumbling they kept making trying to fight. (I miss Hawaiian air.)

Terrible. Would never fly again. Took them several hours to prepare the plane and and reached my destination 4 hours late.

Our boarding was delayed due to two flat tires, but I appreciate the focus on safety. I also appreciated the additional offerings for drinks which never happened before except on Hawaiian Airlines. The hospitality is fantastic! Glad I upgraded to premium seats for the extra leg room as I was getting frustrated when the person in front of me was very restless and kept shifting. Otherwise, it was a fantastic experience.

This flight was how a flight should be. The flight from Hawaii to Seattle was terrible

The staff are friendly and happy, the check in online was easy and dropping off the bags went well with out problem.

We were delayed for 2 hrs without given reason we also need food not snack.

The pilot and crew did everything they possibly could on an airline flight to make everyone comfortable and fed and informed and both flights to and from were flawless and safe and I couldn't imagine flying on another airline when I visit the Hawaiian islands

Worst ever. Flight canceled 2 days in a row. We were stuck with no where to go. 8 hour wait time to talk with anyone when we called Alaska. I want a full refund with retribution

Likes: safety,riendly crew, cleanliness, & movies. What could have been better: crew members speak up and educate parents with toddlers.The toddler was running up and down the isles. What happens if the toddler gets hurts? Who is to blame? Customers pay good money to fly and it’s not fair that it’s ruin by stupid parents that allowed their toddlers to be at risk for injuries.. This made it stressful to watch and be on the same flight.

Comfortable seats. Nice service online. Short flight, so not a lot of time to enjoy.

The flight was done by SkyWest only WIFI no entertainment center are available on the CRJ

My flight was delayed by 4 hours in 30 minute increments. The gate agents were amazing but the communication was not. We were told that there was a maintenance issue but they didn't know what it was. That didn't inspire confidence. Then they said they found it and it was fixed and the pilot just needed to sign off. Then the pilot needed to talk to the other pilot from the arriving flight and we'd be fine. Then we were waiting for the pilot to call back. Then the maintenance issue wasn't fixed. Then they decided we were getting a new plane (why didn't they decide this earlier??). Fine. But then they announced we were changing gates AND terminals. And we were boarding in 20 minutes. So we all had to run to the new terminal gate. We could have taken off at that time, but we then had to wait for all the people who rebooked on a different flight to book this flight again. That took 30+ minutes because there was only one gate agent. When everyone ditched this flight, I saw it as an opportunity to upgrade to comfort. Delta, the greedy jerks they are, charged me $121. After their delay, their fault, their issues, couldn't even discount an upgrade. They only handed out $12 meal vouchers for the delay. I can't even get a snack from starbucks for that.

Love me some Delta. One of the few airlines to recognize and support veterans. Easy boarding, flight was on time and arrived early and the flight attendants were excellent on this flight.

We sat on the runway for over an hour before departure. That was unwelcome.

Crew was nice, meal was good. Entertainment had to be rebooted 3 times and still did not work. Turns out there was residue on screen, it needed to be cleaned to prevent the touchscreen buttons from continuously activating. I had entertainment for the last 45 minutes of a 5 hour 45 minute flight. Really unacceptable for first class. Flight attendent indicated your cleaning solution creates this problem. Seems as if this is widely known, you should be using a different product or cleaning better. Really really disappointing which simply added to the wi fi on your planes with reliably never ever works.

Snacks and included beverages were appreciated. Boarding went smoothly. Plenty of overhead bin space. Seats get very uncomfortable after a couple of hours. After waiting 10 painful minutes for my walker, a very nice Delta guest agent pushed me in a wheelchair to the gate. It was finally delivered to me after another 15 minutes . Our checked bag was on the carousel long b4 I was able to retrieve it. Fortunately it was still there but somewhere along the way the straps we used to secure it were removed and and were not reattached. Wish I had made note of the agents name.

The cabin temperature was nice and cool. The wifi was not working.

First class and monitors weren’t working for mine & my husbands. Eventually fixed, but quite annoyed as we bought first class. Also, No foot rests.

The plane from SNA wouldn’t start after 5 tries. The team gave me an option of flying direct from LAX and giving me a Lyft ride there! Perfect!

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.

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

Cons: Rode a newer Airbus - had the same rattle in the panels above my seat (plastics not secure b/t lighting and panels) as the last Airbus I rode. Cabin was quite warm, borderline hot. Asked to pay for headphones. And the reason I am writing this - when we arrived it took over 20 minutes to get our door open due to nobody on the ground ready for arrival. Likes: Staff was friendly, helpful, and professional. Sandwich was quite good.

We boarded an hour and a half late because a coffee maker leaked in the plane. Then we had to wait for awhile to get off the plane because another plane was in our spot at the terminal. I had plans when I landed that I had to skip so it was pretty disappointing.

Flight crew was great! It’s very special having native Hawaiians as flight attendants. I only fly Hawaiian Airlines when going to the Aloha states. Flight crew with other airlines don’t come close to your employees. Having a breakfast sandwich included on the flight was a treat and delicious. I pack a carry on only because of the extra baggage fee. I wish I didn’t have to haul even that around. I’d check baggage ( eliminate carry on completely)if it was lowered from $30 to $20. $10 is $10, and the extra fee (all airlines have) defeats the joy of finding a good round trip rate, Keep up the good work in knowing the personal qualities and people skills you want for personel you hire.

The check in went smoothly as did the boarding. The seats could be more comfortable for long distance flights. The seating space was better than some flights.

Hello, Bag drop off was cumbersome taking quite long. This should be a much faster process IMO. In flight, there was some disconnect with understanding the beverage cart schedule. we had no return service past the mid point. my seat mate asked for a coffee, was told they would come back later with the coffee, but never returned. The "items for sale" cart was not explained clearly and we missed out on taking part of that service. also the flight attendant moved through quite quickly giving us no time to react. I was happy with the selection of beverages etc. but not knowing or having clear understanding of what and when was troubling.
