The Alaska Airlines lounge at Portland international airport (concourse C) will leave the Priority Pass on November 1st, 2019. The Alaska Airlines lounges at Seattle–Tacoma International Airport (SEA) left the Priority Pass network on September 1st, 2019. All the Alaska lounges have had issues with over crowding and often it wasn’t possible for Priority Pass members to access these lounges anyway.
