I went inside the secret airplane compartment where flight attendants sleep on long-haul flights and was shocked by its size

The flight attendants on long-haul flights don't have the luxury seats as their passengers.

Hidden compartments at the back of planes contain bunks that can be used by flight attendants as a place to rest.

The cabin crew rest areas have no windows or entertainment and are located in tight quarters.

As airliners fly further and more, airlines are continually raising the standards for comfort and luxury for passengers.

However, while passengers enjoy luxury business class and economy seats on certain airlines, flight attendants don't get the same benefits.

The small compartments where flight attendants spend their time are hidden behind wide-body aircraft. These are the crew rest areas, which are appropriately named and where flight attendants go to take a break from their duties or other responsibilities.

These areas are off limits to passengers. Even their entryways are discreetly embedded in the aircraft's architecture to protect against unwanted visitors.

I was on a recent Airbus A350-900 XWB tour and went up to the crew rest area in order to observe how cabin crews spend their time. Here's how it looked.

Cabin crew rest areas are usually located at the back of the economy cabin. It was easy to see how a passenger could walk past the small ladder or doorway marked "crew only".

Because it is hidden from passengers, in an area that is not often used by passengers, its location makes sense. I have never seen a flight attendant climb into the bunks in all my years of travel.

It took me just a few steps to realize that I was actually on an airplane. There were no windows or passenger seats in the space. It was just bunks.

The crew rest area consisted of six bunks and was very small.

The storage space is very limited.

There was also space for items to be stored in pockets along the main aisle.

Every bunk was equipped with a blanket and pillow kit, all wrapped in a seatbelt. It was similar to the one economy passengers get in the cabin below.

In case of turbulence, seatbelts must be worn in the bunks. Even flight attendants must follow the seatbelt sign.

The bunks had no entertainment other than a reading lamp, blanket, or pillow. In the crew rest area, the in-flight entertainment screens that graced cabins below were absent.

This is because airlines want their employees to use the space for rest. It would be distracting to watch TV or movies.

It doesn't prevent flight attendants using their phones. However, a curtain allows for privacy in each bunk.

Although I was unable to get down on one of the bunks, it was difficult to imagine how cramped these quarters would feel. It is, however, a better option than, for example, the last row of economy class.

The commute is easy and requires only a few steps back to the galley. An intercom system in the rest area allows flight attendants to communicate with other crew members.

The compartment looked a lot like the living room of a futuristic spaceship. Moving around in this space would have been easier if there was zero gravity.

Pilots can also have their own areas to rest near the cockpit. It's not much more difficult for them than for flight attendants.

These rest areas are required by law to make long-haul flights possible. Flights between Singapore and the USA can take up to 18 hours. This is why flight attendants must work shifts in order to serve the cabin.

Although it is not as luxurious as a business class lie-flat seat, the setting offers privacy and a short respite from work.

However, those who are afraid of tight spaces should consider the rest area when considering a career as long-haul flight attendant.
