The telescoping joints (110,114) of an articulating aircraft passenger boarding bridge are sealed airtight by an expandable seal (202) in the overlapping and concentric portion between the outer circumference of an internal structure (106) and the interior circumference of an external structure (108). The preferred embodiment is an inflatable bladder (202) with an air outlet (412) and an air inlet (406) to accept compressed air. The bladder (202) expands to seal the gap between the concentric structures when the telescoping structures are immobilized and deflate to allow movement of the telescoping structures. The embodiment may be comprised of a plurality of expandable seals geometrically shaped to form a whole seal.
