A flexible canopy extendable from an aircraft passenger transfer vehicle for mating with passenger airplanes having different fuselage airfoil shaped configurations. The gangway includes a rigid upright frame which carries a pivotal bow frame from its upright sides and includes a lower frame having a threshold plate which is extendable from the gangway. The lower frame includes a crossbar which is connected to the upper bow frame and includes bumpers which encircle the doorway opening in the aircraft. The frames stretch a flexible bellows around the gangway to keep out wind and weather.
