An interior configuration for an aircraft, comprising: a first passageway extending along a longitudinal axis of a fuselage of the aircraft; a second passageway extending along the longitudinal axis; and a transitional region disposed between the first passageway and the second passageway; wherein the transitional region extends perpendicularly to the longitudinal axis, between first and second sides of the fuselage (38, 40), the first and second sides being disposed on opposite sides of the longitudinal axis; wherein the transitional region is configurable from at least a first configuration to at least a second configuration; the first passageway and the second passageway are offset from one another in a lateral direction, perpendicular to the longitudinal axis; the transitional region defines at least a third passageway, disposed at an angle to the longitudinal axis, connecting the first passageway to the second passageway; wherein the transitional region comprises: a first stowage area disposed adjacent to the first side of the fuselage; a second stowage area disposed adjacent to the second side of the fuselage; a first table stowable in the first stowable area; and a second table stowable in the second stowable area; wherein deployment of the first table establishes a first conference table in the transitional space; wherein deployment of the second table establishes a second conference table in the transitional space; and wherein the first table and the second table meet to form a continuous conference table extending from the first side to the second side of the fuselage, thereby obstructing the third passageway. a first passageway extending along a longitudinal axis of a fuselage of the aircraft; a second passageway extending along the longitudinal axis; and a transitional region disposed between the first passageway and the second passageway; wherein the transitional region extends perpendicularly to the longitudinal axis, between first and second sides of the fuselage (38, 40), the first and second sides being disposed on opposite sides of the longitudinal axis; wherein the transitional region is configurable from at least a first configuration to at least a second configuration; the first passageway and the second passageway are offset from one another in a lateral direction, perpendicular to the longitudinal axis; the transitional region defines at least a third passageway, disposed at an angle to the longitudinal axis, connecting the first passageway to the second passageway; wherein the transitional region comprises: a first stowage area disposed adjacent to the first side of the fuselage; a second stowage area disposed adjacent to the second side of the fuselage; a first table stowable in the first stowable area; and a second table stowable in the second stowable area; wherein deployment of the first table establishes a first conference table in the transitional space; wherein deployment of the second table establishes a second conference table in the transitional space; and wherein the first table and the second table meet to form a continuous conference table extending from the first side to the second side of the fuselage, thereby obstructing the third passageway. a first stowage area disposed adjacent to the first side of the fuselage; a second stowage area disposed adjacent to the second side of the fuselage; a first table stowable in the first stowable area; and a second table stowable in the second stowable area; wherein deployment of the first table establishes a first conference table in the transitional space; wherein deployment of the second table establishes a second conference table in the transitional space; and wherein the first table and the second table meet to form a continuous conference table extending from the first side to the second side of the fuselage, thereby obstructing the third passageway.
