Distance and time PDX–ICN
Portland and Seoul sit about 5,276 miles apart. If a nonstop is missing from PDX, timed itineraries near 11 hours of flying usually mean one long-haul plus a shorter feeder — not two equal hops.
Seoul is about 17 hours ahead of Portland on standard time (America/Los_Angeles vs Asia/Seoul). Arrival clocks on ICN are local. That matters more on this pair than on a same-zone hop.
Most Portland–Seoul journeys connect rather than fly nonstop from PDX. Timed one-stop itineraries often bank at Los Angeles International (LAX), San Francisco International (SFO), Seattle-Tacoma International (SEA). That is a pattern, not a promise for your dates. On results, sort by fastest if you care about layover pain, or cheapest if you do not.
