Frequently asked
Which side of the plane avoids the sun from SEA to HNL?
Across typical daytime departures, the sun predominantly hits the left side of the aircraft, so the right side stays shadier. Seat letters start at the left window, so choose the highest window letter (F on narrowbodies, K on many widebodies).
Which side has the sunset views on SEA to HNL flights?
For sunset views, flip the advice: on evening departures the sun sits on the right side of this route, so that is the side with the show.
How long is the flight from SEA to HNL?
The great-circle distance is 4,308 km (2,677 mi), which works out to roughly 5h 34m in the air on this westbound 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.
