Portland International Airport, or just Airport on station signage, is a light rail station in Portland, Oregon, United States, served by TriMet as part of the MAX Light Rail system. It serves Portland International Airport as the eastern terminus of the Red Line, which connects travelers to downtown Portland and Beaverton. The station is attached to ground floor of the main passenger terminal, near the southern end of the arrivals hall and baggage claim area. It features a wedge-shaped island platform, just beyond which both tracks join because the section approaching the terminal is single-tracked.
