Super easy on both flights. Alaska is my go to airline!

Super easy on both flights. Alaska is my go to airline!

I appreciated the check-in at SEATAC - a knowledgeable person was available. I found it easy to ask questions as I went along. I hadn't been at SEATAC for a year and was not that familiar. Parking was fine at Sacramento

My baggage arrived at the airport on an earlier flight. It would have been nice if I would have gotten a text. I waited until all the luggage had arrived before Ivwent to the baggage counter!

I had to check-in my small carry-on at the gate which was inconvenient. According to the people at the gate at SEATAC, there wasn't anymore room in the overhead bins. I obliged. But, when I got inside the aircraft, there was plenty of room EVERYWHERE! It was either miscommunication or incompetence among the Alaska personnel.

Bad. The fight was late and they gave a ridiculous $12 stipend. Better give something or nothing. $12 is ridiculous.

It was a good flight . It wasn’t a full flight so we had space to move around

Great as always. Alaska is my top airline when flying to/from the Pacific NW. I was a bit anxious when I found out I was in a 737 Max, but it went well for us.

1. Stop cancelling flights 2. More overhead luggage space 3. Get rid of the cardboard cups for drinks

The SeaTac tsa process is the dumbest in the land. Slow for no reason. Alaska was fine. We made good time but had no where to park so we sat at the gate for 30 mins.

It was the usual. The entertainment did not work on my iPad but worked on my phone
