Great if it’s not a long flight in coach.

Flight was delayed about 40 minutes by a mechanical problem. This made a long day even longer. Otherwise good.

Much better experience than at SeaTac. No one yelled….all nice The microphone was working for boarding….unlike SeaTac BIGGEST BUMMER….GOT SEATED BACK BY THE BATHROOMS AND YOU IT SMELLED THE WHOLE TRIP. A BLESSING….is they … Left the lights and air on until we were unloaded….UNLIKE SEATAC TO ST. LOUIS….THEY TURNED THE LIGHTS AND AIR OFF IN ALMOST 100 degree weather…IT SUCKED!

After we boarded there was quite a long time before we actually took off, and there were no announcements from crew about why we were delayed. Later when they did make announcements they were largely inaudible. There was no food (other than for purchase) on the flight and no entertainment. Thats not a complaint, just explaining my ratings in those categories. The flight was smooth. Baggage claim was rapid.

Flight attendant missed us first pass with beverage. We had to ask for water on second pass as we were going to be missed again.

I read online that flights longer than 2500 miles also got a complimentary snack pack which did not happen. It just helps break up the long flight when you get a snack here and there. Apreciated the coke and coffee though. Everything was on time and I feel like we maybe arrived earlier than expected as well. I cannot complain.

Jammed up security line. Security personnel excellent but facility is really cramped and lines long. Alaska Airlines was excellent.

We were flying 1st class for a special occasion. This was a Hawaiian airlines flight. It was exceptional. Very comfortable seats and space. Extremely attentive crew. Food was great for airline food. They provided tablets to watch and full headphones to listen. This was the best airline experience I have had in decades.

you could have gotten me there on the day I was supposed to be there, not a day later. Paid for 3 nights at a VRBO and got to spend only 2 nights there.

I requested wheelchair assistance in Seattle transferring gates and in Anchorage to get to baggage claim. No assistance was provided at all.
