The Portland–Seattle route
Portland–Seattle is a short US hop (129 miles, PDX to SEA). Nonstop PDX–SEA is often on the schedule, about 1.5 hours airborne over 129 miles. Ground time and bags often decide whether a cheaper nearby airport is worth it.
For PDX–SEA we show about $49 on the low end and around $90 as a more typical one-way economy total, USD, last reviewed August 2026. A $49 one-way is a sale-shaped guide, not a fare you can screenshot and demand. Taxes, bags, and seats change what you pay on the seller site.
Search PDX to SEA on Azurovia, compare airline-direct and travel-site totals on the same flights, then finish with the seller. We do not ticket. Keep their confirmation for changes.
Distance and time PDX–SEA
Great-circle distance PDX–SEA is about 129 miles. Block time on a nonstop is typically near 1.5 hours; wind, routing, and which runway you use still move the clock. Connections on the same city pair add layover time on top of that flying.
PDX and SEA typically share the same standard-time offset (America/Los_Angeles). Daylight saving can still split them for part of the year — check the local times on the itinerary, not a screenshot from last month.
When PDX–SEA has a nonstop, that is usually the cleanest product. One-stop options still appear — they are worth opening only if the USD total is materially lower after you count the extra ground time.
Airports for Portland to Seattle
Both ends are in the United States: Portland International (PDX) to Seattle-Tacoma International (SEA). This is not an international itinerary, so the usual domestic bag and ID rules apply at the seller. Alternate metro airports can still beat this pair on price.
PDX is the only origin code we list in this metro. SEA is the arrival code we treat as primary for Seattle. A cheaper nearby airport only wins if the transfer still fits your plan. Search with “include nearby airports” when you want those codes in one results list.
