Search FlightsFlying from Portland International Airport (PDX) to Seattle-Tacoma International Airport (SEA) is one of the shortest yet most frequent hops in the Pacific Northwest, perfect for business commuters and weekend adventurers alike. This 130-mile journey typically takes less than an hour in the air, offering breathtaking aerial views of the Cascade Range, including the snow-capped peaks of Mount St. Helens and Mount Rainier on clear days. Whether you are connecting to an international flight in Seattle or visiting for a Mariners game, choosing a flight over the Interstate 5 drive saves hours of potential traffic congestion near Olympia and Tacoma, providing a much more predictable and relaxing travel schedule for busy itineraries.
Travel Tips
First, check-in via your airline's mobile app and use TSA PreCheck if available, as security lines at PDX can fluctuate significantly during early morning business peaks. Second, sit on the right side of the aircraft when flying north for the best views of the Cascade volcanoes, or choose the left side to potentially spot the Olympic Peninsula and the Puget Sound coastline. Third, consider using the Link Light Rail once you land at SEA; it is an affordable and efficient way to reach downtown Seattle or the University District without paying for expensive rideshare surges. Finally, pack a light jacket regardless of the season, as the microclimates between the Willamette Valley and the Puget Sound often lead to unexpected temperature shifts or misty conditions upon arrival.
