A crew rest compartment (crew rest) is a section of an airliner dedicated for breaks and sleeping by crew members, usually located above or adjacent to the passenger compartment. Crew rest compartments are normally segregated, with separate compartments for the 
On long flights, crew members may sleep in crew rest compartments during off-duty periods. 
The FAA rest facility classifications from highest to lowest:
* Class 1 rest facility: This class requires access to an area physically separated from the cockpit and the passenger cabin; contain bunks or other flat areas for sleeping; have provisions for sound and lighting isolation.
* Class 2 rest facility: This class requires access to at least a lie flat seat and separation from passengers by a curtain.
* Class 3 rest facility: This class only requires a cabin seat that is able to recline and has foot support.
Crew rest design and safety considerations are similar between international regulators, for example the

Aircrew, also called flight crew, are personnel who operate an aircraft while in flight. The composition of a flight's crew depends on the type of aircraft, plus the flight's duration and purpose.

Passengers are restricted from accessing crew rest compartments by regulations; their entrances may be secured by locks and may require ascending a ladder for access.
Crew rest compartments may not normally be used during taxi, takeoff, or landing maneuvers (TT&L). In flight crew rests that contain standard seats, an exception may be made to allow seated crew during TT&L.

(FAA) defines three classes of crew rest facilities, dependent on the number of crew and the duration of the flight. Crew rest periods may be provided in higher classed rest areas than required, for example some airplanes may not have a class 2 rest facility, providing breaks in a crew rest.

(EASA) regulations for access control, communications, and signage are similar to those of the FAA's. By following such regulatory Bilateral Aviation Safety Agreements (which avoid contradictory minimum specifications), aircraft manufacturers can design crew rests to meet the requirements in many markets.
