All flights were on time. No crowded and had empty seats. All flight attendents were great.

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.

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.

Good leg room, no problem with overhead storage and the staff was super helpful.

Good experience, although it was a little cramped being a tall person. Otherwise everything went smoothly and professionally though

The registration was chaotic. The kiosks didn't work for most people, and most had to do registration and receive boarding slips with a person. It took about an hour to get through he process, and I was worrying that I will be late to the flight. However, the personnel was great - courteous, professional, and was able to work through the problems.

The boarding was easy, the crew was amazing, i just wish the onboard entertainment selection would have been better for such a long flight.

This flight had mechanical issues. I changed flights, which Alaska Customer Service handled beautifully. Then that flight was an hour late. I was originally supposed to land in San Diego at 730pm and I landed at midnight,

more time in layover in seattle because security for passport is a very long line

Crew was outstanding. Flight was fine. Food was a joke! I didn't get the priority I paid for!! That pissed me off since I paid extra!!!
