Hello, In my experience with Alaska Airlines at Minneapolis–Saint Paul International Airport, I flew from Terminal 1. I found the terminal easy to locate and well organized. The check-in process was quick and the staff were helpful. Security lines moved well, so I didn’t feel rushed. There were food places and shops nearby while I waited. If you’re asking, What terminal is Alaska Airlines at MSP, the answer is Terminal 1, and this helped me avoid confusion on travel day.
