They offer the only direct flight from Seattle to Pittsburgh.

Seattle airport is a mess. New bag tag system has potential, but you need more signage to guide passengers through the process as to where to go next. Told to go in one direction and then met with a very rude agent when we did. He blamed his attitude on all the folks flying over labor day that were paying his salary. Gate area for D3 is a mess compared to the North terminal. Overall Alaska is number 1 in my book.

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.

The airline staff was great! The best safety review ive ever had!

Agent boarding us in San Diego lectured me on showing up on time for the flight, and said that if I had been three minutes later, he would have denied myself and my wife boarding. Our trusted traveler numbers were not in the system, even though I entered them when I bought the tickets. Our food orders were not in the system, even though I entered them prior to the flight. My wife requires a wheelchair, and that was delayed on both flights.

Why was I charged for a glass of wine on one flight and not on another? Why no movie or TVs? It was a long flight.

I liked that it didn't take 10 hours to drive here. Super short trip!

Wheelchair assistance was provided in Seattle and was very gratefully accepted. Thank you to the Alaska staff.

I payed for a window seat and was assigned the middle seat. The window seat just so happened to be open. Which made the ride alot more comfortable. I think I should get what I pay for without having to buy extra fight protection. If I pay for it first that should be the end of that seats history because it's now spoken for. That alone might make me think twice about using this again

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.

Everything was great except having to check in at Alaska. That was a surprise and took extra time and effort. Should have been explained somewhere maybe on the HA electronic ticket.

It was clean and the crew was great. I wish the chairs could recline just a little more and you would provide small pillows for people with bad backs. My back is fused and a little support would be great.

I accidentally made this purchase and they wouldn’t refund me even though I called immediately to cancel it.

The flight was delayed and they didn’t have a pilot for the flight. Seemed very unorganized and took way longer than expected.

You. Changed my AIRLINE, CONFIRMATION CODE, TERMINAL. AND GATE COMM N CATION. WAS POOR AND SUBOPTITMUM AND RIDICULOUS MY AIRLINE WAS HAWAIIN. ,THEN SUDDENLY. YOU SAY IT WAS ALASKA Give me a break,,Black is not White I could not check in over the phone...all I received was Error. And info from Hawaiian air agent saying tooooo many people were trying to check in causing the problem On the other hand I am alive

Hawaiian airlines has awful customer service. Told me to keep a flight I wasn’t boarding, instead of rebooking me under two separate reservations, which caused my whole reservation to be canceled. Major issues with leadership and management. The staff at Hilo was reluctant to give me a refund, so I had to by a first class ticket in order to get on a flight the same time as my partner. The blame was pointed at me without sincere apology until the supervisor came out, who also apparently had no authority to refund me. Still waiting on correspondence from the airline days later.

I could not believe that on a 5 hour plus flight we were not given a complimentary meal . That should be illegal. Or it would be nice to be informed beforehand that a complimentary meal would not be provided. The wording in the email I got about pre ordering food was phrased in a way that made the food seem like it would be free. Very misleading! Also during boarding we were informed there would be empty seats we could move to if we wanted, all we had to do was wait for an announcement, however an announcement was never made. Then when we tried to change seats ourselves we were singled out over the loud speaker and told we could not move without asking. Then the flight was about to take off , so we didn’t have time to ask . Then we were told we could not move to the exit row because you had to pay for those seats, but we were not told where we could move. Also no one was in the exit rows so , if something happened no one would be there to assist the passengers. Also people should be allowed to move there if the airline wasn’t able to sell them. One passenger asked if he could pay for the upgrade and the flight attendant said she did not have the capability to charge for the seat on her mobile device, so the airline ended up losing possible income anyways . So why not let people move there during flight if you have no way to charge them? Then the landing was bumpy and awful and many passengers complained out loud when we landed .

I like that you have eliminated plastic cups, bottles and straws. The crew was conscientious about separating the used paper cups from the trash. This change to paper is a great move and makes me want to choose Alaska when I fly.

Boarding was fine, but once on we waited for 45 minutes to take off. This caused me to almost miss my connection. Once the second flight was boarded we waited again for 20-30 minutes to take off.

Attendants seemed un-engaged and indifferent when asked for assistance.
