An aircraft cart retention system may include at least one aircraft cart retention device. The at least one aircraft cart retention device may be configured to retain an aircraft cart in a position proximate to an exterior surface of the structure with at least two combined points of contact during non-taxi, takeoff, or landing (non-TTL) stages of flight when the at least one aircraft cart retention device is in at least one deployed position. The at least one aircraft cart retention device may be configured to allow the aircraft cart to be removed from the position proximate to the exterior surface of the structure when the at least one aircraft cart retention device is in the stowed position.
