I went Premium otherwise it would have been a long wait. On board I only asked for a cup of hot water and got lukewarm. Cabin crew have poor to no service. But great flight; it went smooth.

I went Premium otherwise it would have been a long wait. On board I only asked for a cup of hot water and got lukewarm. Cabin crew have poor to no service. But great flight; it went smooth.

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

Great flight Pilot was friendly and kept us informed when small delay to de ice plane

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
