Portland International Airport (PDX) shorthand and local usage

Portland International Airport, commonly abbreviated PDX, has the mailing address listed here and serves as the primary air hub for the Portland metropolitan area. The three-letter airport code 'PDX' is widely used in local business names, event titles, and casual speech around the city. That ubiquity of 'PDX' has become a recurring, tongue-in-cheek shorthand in local jokes and branding about everything from coffee to clothing.
