A jump seat (or jumpseat), in aviation refers to an auxiliary seat for individuals—other than normal passengers—who are not operating the aircraft.[1] 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 United States c. 1860 for a movable carriage seat.[citation needed]
