We were in first class. Food was surprisingly good. Boarding was easy. Seats were lumpy. No video screen ...really? Service was good. Phone support was good

We were in 1st Class. Excellent service. Easy boarding. No too difficult to speak with someone on the phone. Breakfast was not eatable for me. No screen to watch movies. I don't have or want a tablet. This is first class there should be screens. Even if I had a tablet there was no place to put it. There is a place to put a tablet in economy. Seats were a bit lumpy.

Everything was fine, although I expected to be given a light snack, like other airlines do, but that didn't happen. Nothing at all.

6.0 Okay

Way too warm for that length of flight!! If the pretzel bag gets any smaller, there won't even be any pretzels to eat!! Crew didn't talk. $99 just for an aisle seat is ludicrous!! Probably won't fly Alaska again.

Our big luggage never made it to Boston. Very crucial to get it ASAP as heart medication is in there.

Boarding the flight crew was super nice. They came with drinks 2 times during the 4 hour flight from San Antonio to Seattle and they gave a snack. If you wanted WIFI it was $8 and they had movies, some to purchase and some free. The way the plane was packed you would think it would be free or cheaper. Our pilot got us there before our actual arrival time l, we arrived at 9 not 930.

Had to go in the bus to board the flight. Was traveling with just a carry on, but Carry on luggage was recommended to be checked in and it took a while to come to the baggage claim.
