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.

Only issue was the 2 hr delay after an 8 hr layover. Very long day.

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

Awful. We got the last seats and they don't recline. We've been on this horrible journey since 6am and won't get to our destination almost a full day later. Oh and no food, either. Never again.

We were amazed by the amazing food, comfort and service received in our coach seats. Pleasantly surprised we received breakfast and great beverages for no charge. Bag check fee was on $35. The crew was so kind and helpful. Highly recommend!

We purchased tickets and were last to board while standby passengers were boarding before us. The WiFi wasn't working and the same thing happened on our last Alaska flight. The snack provided was vegan I wasn't going to chance eating that on a 6 hour flight incase it didn't agree with me.

The ground crew stocking the plane should have put some water on the plane at the very least. The cabin crew made no attempt to remediate the freezing interior for 5 hours. They had the temerity to tell passengers that they( the crew) liked the coldness of the 5 hour flight.

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.

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.

The flight from HON to Hilo caused a few problems, but we were helped by the checking agent at Hawaiian Airlines with tech assistance. My wife & I are in our 70's and not QR code savvy. But we are learning.

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.
