Taking a flight from one side of the world to the other can be a tiring experience for a traveler, but think about what it must be like for the flight attendants and pilots, who are on-call—and often on their feet—throughout the duration of the trip. They’ve got to get some downtime, too, but where do they rest?

According to INSIDER, there are tiny bedroom compartments hidden above many first class cabins, which are accessible via a secret staircase, usually behind the cockpit (though some are accessible at the rear of the plane). The bedrooms are for the use of the flight crew only and are available on most airplanes that are built for long-haul flights, such as the Boeing 777 and 787 Dreamliner, and the Airbus A380.

Flight attendants can take a break and catch a few winks in these designated sleeping areas, which typically feature six to 10 beds with pillows and blankets in a variety of bunks or side-by-side beds, which are divided by privacy curtains. Each bunk is about six feet long and 2.5 feet wide, which isn’t exactly what you’d call “spacious.” However, some airlines offer pajamas and entertainment centers for some added relaxation.

Boeing 777 pilots might have some of the best accommodations: They have their own overhead sleeping compartments with two roomy beds, two business-class seats, and more than enough room for a closet, sink, or private lavatory, depending on the airline.
