A jet bridge (also termed jetway, jetwalk, airgate, gangway, aerobridge/airbridge, skybridge, airtube, or its official industry name passenger boarding bridge (PBB)) is an enclosed, movable connector which most commonly extends from an airport terminal gate to an airplane, and in some instances from a port to a boat or ship, allowing passengers to board and disembark without going outside and being exposed to harsh weather. Depending on building design, sill heights, fueling positions, and operational requirements, a jet bridge may be fixed or movable, swinging radially, and/or extending in length.
The jetway was invented by Frank Der Yuen.
