SeaTac airport hottible No signage to tell you where to go Took one and half hour to make to gate after being dropped at airport HORRIBLE LOTS OF yelling at patrons EXTREMELY HORRIBLE AND SCARY!

Late boarding, but the flight was smooth and the crew was accommodating.

The flight was delayed almost an hour. No wifi on flight.

Flight was OK, landing not good, boarding was ridiculous. Flight was to load at gate n11 25 minutes before boarding time it was changed to s5 which is 3 tram connections on the other side of the airport, I'm handicapped and even getting a sky cap took 10 minutes needless to say just made it to boarding only because it was delayed. I did learn a valuable lesson don't show up for flight 2 hours early.

Leg room was quite OK. Customer service from the crew was spot on.

The Alaska airlines flight attendants were great. Boarding went smoothly. The cabin was comfortable intitially, and seemed stuffy later. I tried to open the vents but they were not very powerful to cool our seating down. Ride was smooth. They left the gate early and arrived early. The pubic address used by attendants was scratchy. No, it wasn’t their voices it was their system.

I was trying to switch from a middle seat to an aisle seat which usually I am able to. They did not want to switch seats for me and we're trying to charge me $80. I was sitting next to a bunch of kids that were really loud. Thankfully, I was seating between two very kind people.

service was good. flight attendants were friendly. flight was smooth.

Great. They got us on an earlier flight. Really appreciated that

The flight was bumpy and hard landing. No in-flight entertainment onboard couldn't connect to wifi.
