A modular lower lobe passenger rest cabin includes passenger rest compartments oriented longitudinally along the roll axis and laterally along the pitch axis. Partial passenger rest compartments are defined by the modular lower lobe passenger rest cabin such that when two modular lower lobe passenger rest cabins are installed in a cargo deck of an aircraft, the partial passenger rest compartments define a single passenger rest compartment or aisle from space that would otherwise be insufficient for the purpose.

A passenger cabin monitoring system includes infrared cameras disposed in respective passenger rest compartments, a flight attendant information system including at least one display and at least one speaker, and a computing device in communication with the infrared cameras and the flight attendant information system. The computing device is configured to detect a temperature of a portion of passenger rest compartment based on one or more thermal images generated by a respective infrared camera of the passenger rest compartment. The computing device is further configured to compare the temperature of the portion of the passenger rest compartment with a predetermined critical temperature and provide an audible alert and/or a visual alert via the flight attendant information system to indicate a critical status of the passenger rest compartment when the temperature of the portion of the passenger rest compartment is above the predetermined critical temperature.

A passenger cabin area includes at least one aisle extending along a longitudinal axis of the passenger cabin area, a seating area next to the aisle in the direction of a transverse axis, perpendicular to the longitudinal axis, of the passenger cabin area and in which at least one passenger seat is provided, and a plurality of sleeping berths arranged above the seating area in the direction of a vertical axis, perpendicular to the longitudinal axis and the transverse axis, of the passenger cabin area. Each sleeping berth is accessible from the aisle of the passenger cabin area via a stairway element assigned individually to the sleeping berth.

A vehicle includes a fuselage defining an interior cabin and a bunk within the interior cabin. The bunk has a base wall and a ceiling that extend a length of the bunk from a first end wall to a second end wall. The bunk includes one or more removable partition walls that divide the bunk into multiple pet compartments between the first and second end walls. The pet compartments are configured to contain pets therein. Each of the partition walls is removably secured to both the base wall and the ceiling.

A seating arrangement includes a seat with a seating surface and a top bunk disposed adjacent to the seat. The seat and the top bunk are configurable between a first configuration and a second configuration. In the first configuration, the seat accommodates a user in a seated position and the top bunk is stowed. In the second configuration, the seat and the top bunk form a bunk bed configured to accommodate users in prone positions. In the first configuration, the seating surface is disposed at a first predetermined height. In addition, in the second configuration, the seating surface is disposed at a second predetermined height that is lower than the first predetermined height.
