A jump seat (or jumpseat), in aviation refers to an auxiliary seat for individuals—other than normal passengers—who are not operating the aircraft. In general, the term 'jump seat' can also refer to a seat in any type of vehicle which can fold up out of the way; vehicles include carriages, automobiles, vans, buses, fire tenders, and taxicabs. The term originated in the USA c. 1860 for a movable carriage seat.
