Frequently asked
Which side of the plane avoids the sun from ICN to SEA?
Across typical daytime departures, the sun predominantly hits the right side of the aircraft, so the left side stays shadier. Seat letters start at the left window, so choose an A seat.
Which side has the sunset views on ICN to SEA flights?
For sunrise or sunset views, sit on the side the table marks as the sun side for your departure time — that is where the light is.
How long is the flight from ICN to SEA?
The great-circle distance is 8,373 km (5,203 mi), which works out to roughly 10h 21m in the air on this northbound routing. Winds and routing move the real block time around that estimate.
Does the date or departure time change the answer?
Yes — that is why the table shows both. The sun's path shifts with the season, and a morning departure can put the glare on the opposite side compared to an evening one. For a specific flight, the calculator samples the sun along the whole route for your exact date and time.
