Where a direction shows “—” we track it as an operating nonstop but hold no schedule sample for it — we would rather show nothing than guess.

Aircraft assignments change by season and by time of day.
On a long east–west route like this one the two directions do not take the same time. Aircraft flying eastbound ride the mid-latitude jet stream and typically arrive earlier than the westbound leg, which flies into it. The difference is commonly 30 to 90 minutes on transatlantic and transpacific flights, and it varies by season. The estimate above does not model wind — treat it as a midpoint and check the airline's own timetable for the block time on your date.
The distance between Ronald Reagan Washington National Airport and Portland International Airport is 2,345 miles, or 3,774 kilometres.

Measured airport to airport. The actual track is longer — aircraft follow airways, avoid restricted airspace and route around weather.
Yes. Alaska Airlines flies the route nonstop, with about 7 departures a week across both directions. The route is in our live nonstop dataset, last seeded 2026-07-07.
About 5h 06m in the air. That is a great-circle estimate from the 2,345-mile distance, not a scheduled block time — an airline's published time will differ by roughly 15 to 45 minutes depending on routing, winds and taxi.
