Sit on the Right side of the plane for the best views on flights from Portland to Seoul. While takeoff offers dramatic Cascade views, the landing approach into Incheon provides more sustained visual interest—the Han River estuary, reclaimed-land airport islands, and the transition from ocean to continental landmass are more visually distinctive than the departure climb. Right seats capture this sequence better.

During takeoff from Portland International (PDX), sit on the Left side for the best views. PDX typically departs runways 28L/R or 10L/R depending on wind. Left seats on northbound departures (runway 28) capture the Cascade Range immediately, with Mount Hood dominating the eastern horizon. On westbound initial headings, you'll see the Willamette River valley and Portland's urban grid before climbing over the Cascades. Notable sights include: Mount Hood (11,240 ft, ~50 miles east), Cascade Range spine, Willamette River valley floor, Portland metro area grid.

When landing at Incheon International (ICN), sit on the Right side for the best views. Incheon lies west of Seoul on the Yellow Sea coast. Approaching from the east (typical for trans-Pacific arrivals), right-side seats capture the Korean peninsula's western coastline, the Han River estuary, and Incheon's reclaimed land airport complex. You'll see the dramatic transition from mountains to coastal plains. Notable sights include: Han River estuary and delta, Incheon International Airport's artificial islands, Seoul metropolitan area sprawl to the east, Korean peninsula's western mountain ridges.

The flight from Portland International (PDX) to Incheon International (ICN) takes Approximately 11.5 to 12.5 hours.

The flight path crosses the North Pacific, passing north of the Hawaiian Islands (typically 200+ miles north of Oahu). You'll cross the International Date Line around 8-9 hours into flight. The Pacific crossing offers minimal visual landmarks—open ocean, occasional weather systems, and at high altitude the curvature of Earth becomes apparent. Approaching the Asian continent, you'll see the Japanese archipelago (Honshu) off the right wing roughly 1-2 hours before Incheon, followed by the Korean peninsula's mountainous spine and eventual descent toward the Yellow Sea coast.
