Airports in Multnomah County, Oregon
Multnomah County is home to Portland International Airport (PDX), Oregon's primary commercial air hub and one of the most celebrated airports in the Pacific Northwest. Located at 7000 NE Airport Way, Portland, OR 97218, PDX sits just 6 miles northeast of downtown Portland, making it one of the most conveniently positioned major airports in the United States.

In 2025, Condé Nast Traveler named PDX one of the most beautiful airports in the world, recognizing its distinctive design and passenger experience.
The terminal at PDX is organized around four concourses — B, C, D, and E — offering travelers a wide range of gates and amenities spread across a well-connected facility. The airport operates two primary runways: Runway 10R/28L stretches 11,000 feet, accommodating the largest widebody aircraft in commercial service, while Runway 10L/28R measures 9,825 feet, providing full capacity for all domestic and most international operations. This runway infrastructure supports the airport's diverse traffic mix, from regional turboprops to transoceanic widebody jets.
PDX serves 85 destinations in total — 75 domestic and 10 international — connecting Multnomah County residents and visitors to cities across North America, Europe, and Asia. Alaska Airlines is the dominant carrier at PDX, operating 41 routes that span the continental United States, Alaska, Hawaii, and select international markets. Southwest Airlines, Delta Air Lines, United Airlines, and American Airlines all maintain strong domestic networks from Portland. For international travelers, British Airways connects PDX to London Heathrow, Cathay Pacific provides service to Hong Kong, KLM offers flights to Amsterdam, and Icelandair links Portland to Reykjavik with onward connections to European destinations.
A landmark moment in PDX's recent history came on August 14, 2024, when the airport officially opened its major new terminal expansion. This project significantly increased the airport's capacity, modernized the passenger experience, and added new concourse space to accommodate growing demand. The expansion project was one of the largest infrastructure investments in Portland's history and reflects the Port of Portland's commitment to keeping PDX competitive as a West Coast international gateway.
Beyond passenger operations, PDX handles a substantial volume of air cargo. Its location on the Columbia River corridor and proximity to major logistics hubs makes it an important freight facility for the Pacific Northwest, supporting e-commerce, agricultural exports, and time-sensitive shipments moving through the region.
