Portland International Airport (PDX) stands as the biggest airport in Oregon, handling approximately 90% of the state’s passenger air travel and more than 95% of its air cargo. Located just 12 miles northeast of downtown Portland in Multnomah County, PDX serves as a critical gateway for travelers visiting the Pacific Northwest.
Why PDX is Oregon’s Largest Airport
With nearly 20 million passengers passing through annually, Portland International Airport dwarfs every other airport in Oregon by a significant margin. In 2024, PDX served 17.5 million passengers, cementing its position as the primary aviation hub for the entire state. The airport covers an impressive 3,000 acres and operates as a hub for Alaska Airlines, providing extensive connectivity throughout the western United States and beyond.
The airport handles flights to destinations across the United States, Canada, Mexico, the United Kingdom, Netherlands, Germany, and Iceland, making it the only Oregon airport with significant international service. In July 2025 alone, over 17,000 flights took off or landed at PDX.
Award-Winning Terminal Design
Portland International Airport has earned a reputation as one of America’s most beloved airports. Travelers named PDX the best airport in the United States in Travel + Leisure’s survey, a distinction it held every year from 2013 to 2019 and again in 2021. In 2025, Conde Nast Traveler recognized PDX as one of “The World’s Most Beautiful Airports.”
The airport’s appeal stems from its thoughtful design and Pacific Northwest character. Phase one of a major terminal renovation opened in August 2024, part of the $2 billion PDX Next modernization program. This ambitious project brings Pacific Northwest-inspired architecture to the facility, featuring the first mass timber roof at any major U.S. airport. The construction is expected to complete in early 2026.
Terminal Layout and Gates
PDX operates one passenger terminal with four concourses designated B, C, D, and E, totaling 60 gates. The straightforward layout makes navigation simple compared to larger hub airports. Most travelers can reach their gates within a short walk from security, and the terminal’s design prioritizes natural light and open spaces.
The airport features an excellent selection of local restaurants and shops that reflect Portland’s unique culture. Passengers can enjoy craft beer from local breweries, artisan coffee, and farm-to-table dining options before their flights. Shopping includes Powell’s Books, Nike, and numerous locally-owned boutiques.
Airlines Serving PDX
As an Alaska Airlines hub, PDX offers extensive West Coast connectivity. In May 2025, Alaska Airlines began shifting additional connecting flights from Seattle to Portland to relieve overcrowding at Seattle-Tacoma International Airport, increasing PDX’s importance as a regional hub.
Major carriers serving Portland International Airport include:
- Alaska Airlines (hub)
- Delta Air Lines

Getting To and From PDX
Portland International Airport offers excellent ground transportation options that set it apart from many American airports:

Rideshare and Taxis: Uber and Lyft operate designated pickup zones outside the terminal. Traditional taxi service is also available curbside.

Comparing Oregon Airports
While PDX dominates Oregon aviation, the state has several smaller regional airports. Eugene Airport (EUG) serves the state’s second-largest city but handles only a fraction of PDX’s passenger volume. Redmond Municipal Airport (RDM) serves Central Oregon and Bend, while Medford’s Rogue Valley International Airport (MFR) provides service to southern Oregon.
None of these regional airports approach Portland International in size, service options, or passenger volume. For most travelers visiting or departing Oregon, PDX remains the clear choice for domestic and international flights.
Planning Your Visit
When traveling through Portland International Airport, arrive at least two hours before domestic flights and three hours before international departures. TSA PreCheck and CLEAR lanes help expedite security screening. The airport’s free Wi-Fi covers the entire terminal, and charging stations are available throughout all concourses.
Portland International Airport continues to earn its reputation as Oregon’s premier aviation facility, combining efficient operations with genuine Northwest hospitality.
