Flight attendants were kind. Until the plane arrived and had a slow taxi. I was on the tail end of the plane and informed the attendants I had a connecting flight. They didn't do anything to help me get off in a more timely manner. Nor did they contact my connecting flight to let them know I was on my way. By the time it was our rows turn my connecting flight across the terminal D gate to C gate was already boarding. I had to run the whole way through the terminal and hope I caught a train inntime. They were calling my name last call by the time arrived at the gate. Then my connecting flight ticket would not work and a new ticket had to be issued requiring presenting my ID again

Flew first class. No headrest screens on either flight and the one flight had no foot rests either.

We tried for days to use online Alaska Airline app we needed to know what Gate to depart from . When we got there we were given a paper boarding ticket with the wrong gate on it . We almost missed this flight . It caused great stress and caused a health side effect. The previous flights April 24 started hour late mechanical issues . We were not allowed to depart plane in time to get correct gate and missed our flight .

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.

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.

Alaska Airlines has horrible customer service. After sitting in a packed airplane for over an hour, they decided to cancel our flight and had us deplane. Instead of helping us nearby, we had to ride two trains (in Seattle Airport), from the S-Gates to the C-Gates; only to stand in a line for 3 and a half hours. Throughout the 3 hours, there was often 1 agent at the customer service counter to help the passengers trying to get information and accommodation on a flight that they cancelled. Do better!

Confusing now Hawaiian and Alaskan have merged, hard to check in - they need to uncomplicated things.

The stewards were too loud and chatty with each other

If the flight from Seattle to Eugene hadn’t been delayed for mechanical reasons we never would have made it. 45 minutes is not enough time to deplane and get clear across a big airport like SeaTac.

This was a smooth ride all the way with plenty of space in main cabin for my 6 foot frame over 5.5 hours. The stewards were pleasant and attentive. We bought the tapas box which proved to adequate for us on this flight. It was pretty hard to find restaurant food to go that is vegan for us in Kona Airport so buying this helped lots.

Delayed and cancelled flights were hard and very stressful, both ways!

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

Our flight was delayed, which I know things can happen. The bathrooms were dirty and a mess. It took over an hour to get our bags after the plane landed. Every flight was on the same 2 baggage claims. You would thing if we spent over 5 hours on a flight we would get more then a tiny bag of pretzels. The movie and tv choices were mid.

The flight was very smooth and the landing was AMAZING! I have flight anxiety and it didnt peak once! :) Thank you to the pilots and crew!!

Pillows and blankets were nice since it was an overnight flight, but the seats should be larger and there should be more space between rows so we have more leg room.

If I knew I would be on Alaska Airlines flying back, I never would have bought the ticket. My flight kept getting delayed and Alaska always seems to be late which is why I don’t fly on them.

When I scheduled using Kayak I couldn’t I couldn’t select my own seats and the seats I got were undesirable. I’ll choose to schedule with the carrier directly in the future if I choose Hawaii Air in the future. The Staff was excellent under the circumstances.

We enjoyed our first flight through Hawaiian Airlines. Very smooth landing. Mahalo

Extremely frustrated that I followed all directions and Hawaiian Airlines made me leave my surfboard at the airport and refused to let me check it.

- Zero leg room. - No way to enjoy the VERY limited entertainment due to the lack of headphones / outlets - No Wifi - No charging outlet - No complimentary light snacks like pretzels - No masks to handout when the flight is full of sick - people (me and my son got sick upon our return) smh
