Claim 0:
1. An expandable aircraft lavatory comprising:
an aircraft lavatory first footprint in an unexpanded aircraft lavatory configuration, said aircraft lavatory first footprint having a first aircraft lavatory footprint area, said first aircraft lavatory footprint bounded by at least three first aircraft lavatory footprint wall sections and a movable expandable wall-door, said movable expandable wall-door movable from a first aircraft lavatory footprint closed position to a first aircraft lavatory footprint open position, said movable expandable wall-door comprising:
a wall-door interior;
a wall-door exterior;
at least one expandable door panel, said expandable door panel in an expandable door panel stowed configuration in the aircraft lavatory first footprint, said expandable door panel configured to be extended from the expandable door panel stowed configuration into an expanded door panel deployed configuration;

an aircraft lavatory second footprint in an expanded aircraft lavatory configuration, said aircraft lavatory second footprint having an aircraft lavatory second footprint area, said aircraft lavatory second footprint bounded by at least three aircraft lavatory second footprint wall sections and the movable expandable wall-door, said movable expandable wall-door configured to be moved through a range of motion from an aircraft lavatory first footprint closed position to an aircraft lavatory second footprint closed position, said movable expandable wall-door in the aircraft lavatory second footprint configured to abut an aircraft cabin aisle;
wherein said aircraft lavatory second footprint area is greater than the aircraft lavatory first footprint area;
wherein in the unexpanded aircraft lavatory configuration and in the first aircraft lavatory footprint the movable expandable wall-door in the aircraft lavatory first footprint closed position is configured to abut an aircraft door entry area; and
wherein in the expanded aircraft lavatory configuration and in the aircraft lavatory second footprint the movable expandable wall-door in the aircraft lavatory second footprint closed position is configured to abut an aircraft aisle and is further configured to impede access to the aircraft door entry area; and
wherein the aircraft lavatory second footprint further comprises:
at least one retractable barrier wall, said at least one retractable barrier wall positioned proximate to an aircraft door bustle of an aircraft door when the expandable aircraft lavatory is in the expanded aircraft lavatory configuration, said at least one retractable barrier wall configured to engage at least two of the second aircraft lavatory footprint wall sections.
