# FlightSide — Which Side of the Plane Gets the Sun?

Find your perfect window seat before you book. FlightSide tells you which
side of the plane gets direct sun and which stays shaded.

Enter a departure airport, arrival airport, and departure date/time.
FlightSide calculates how the sun moves along the route and shows which
side of the plane gets more direct sunlight and which side stays in cabin
shade, plus the day/night split for the whole flight.
