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.

Flight Path
Portland to Seoul is 5,275 miles (8,490 km), a flight of about 12 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.
