This idiom comes from the early days of aviation. Aircraft initially had few navigation aids and flying was accomplished by means of the pilot's judgment. As the plane responded to the pilots actions at the controls, the pilot could feel that response at the largest point of contact between himself and the plane: the seat of his pants. The term emerged in the 1930s and was first widely used in reports of Douglas Corrigan's flight from the USA to Ireland in 1938.
