The line to get in took 2 hours. When I finally got to the gate they had a computer issue and could not read my boarding pass which for once (never again) I had not printed out. Despite the fact that I had checked in the night before and had my confirmation they would not let me board. No assistance from Alaska whatsoever I was forced to walk back to the agent, wait in a huge line and miss my flight. They were not able to get me on another flight until 10 hours later. I received a $10 food voucher which barely got me a cup of coffee.
