Systems for storing an on-board-wheelchair on-board an aircraft are provided. In order to provide a stowage possibility for an on-board-wheelchair that requires less valuable space, an aircraft cabin is provided that comprises an on-board space unit and at least one stowage compartment for an on-board-wheelchair. The on-board space unit provides an on-board function, and is surrounded by a housing wall structure. The stowage compartment provides space to accommodate an on-board-wheelchair. The stowage compartment is at least partly surrounded by an enclosure structure. At least a part of the enclosure structure is provided by the housing wall structure.
