KAYAK’s top tips for finding a cheap flight from Seattle to Portland

  • When traveling to Portland, the most convenient airport to arrive at is Portland International Airport (PDX). The airport offers several facilities designed to make your travel experience remarkable. For example, they have prayer rooms, interfaith centers, on-site restaurants, and free internet that allows you to stay connected with your loved ones.
  • Take some time to admire and get inspired by the airport's art exhibition and music performances. Portland International Airport has an art program that provides insight into the region's dynamic culture. The finest works by Portland artists are exhibited throughout the airport terminal. Forget the typical airport muzak; the airport's music program allows musicians to play live music that is pleasing and calming for travelers. In addition, you will find the Hollywood Theatre on Concourse C, which entertains passengers with films.
  • You can leave Seattle from Seattle-Tacoma International Airport (SEA), Seattle Lake Union SPB Airport, or Seattle Boeing Field Airport. Seattle-Tacoma International Airport is the primary airport serving this region but is farther from Seattle than the others.

  • Seattle-Tacoma International Airport (SEA) has convenient on-site and off-site parking options, allowing passengers to park their cars. The parking spaces offer the closest airport parking flexibility to fit your budget and needs. We recommend pre-booking to avoid inconveniences and because the airport provides discounts when you pre-book.

Some of them include The Club at SEA, The United Club, The American Express Centurion Lounge, Delta Sky Club, Alaska Lounge, and USO Center. Most of them can be found on Concourse A and offer amenities such as free Wi-Fi and complimentary snacks.
