See the secret airplane bedrooms where flight attendants sleep on long-haul flights

Flight attendants are humans too, and just like everyone else, they need to sleep on long-haul flights.

But where do they do it?

Most Boeing 777 and 787 airliners have a secret stairway that leads to a tiny set of windowless bedrooms for the cabin crew — and few people know they even exist.

See what the secret cabins look like.

An earlier version of this story was written by Jim Edwards.

It depends on the plane, but usually crew rest areas are hidden behind the cockpit, above first class, like on this Boeing 777.

Secret stairs lead up to the bedrooms where the cabin crew sleeps.

The steps are hidden behind an inconspicuous door that's usually near the cockpit. Usually, a code or key is needed to open it.

But some cabins are entered through a secret hatch that looks like a typical overhead bin. This is on American Airline's Boeing 773.

A sign divulges what's behind these doors (eight crew member bunks), though you've probably never read it that closely.
