Have you ever wondered where the flight crew get some shut-eye during a long haul flight ?
Unlike the cramped economy seats, pilots are able to put their feet up in relative comfort during the red-eye. Crews on some Boeing 777 and Boeing 787 planes will even get their own beds.
From the looks of things, it's still a bit cramped but at leas they're able to stretch out and lie down. In fact, some crew members said they even bring their own pyjamas.
Some of these jets feature a secret staircase which leads crew to their own sleeping quarters.
But while they might offer a chance to rest your head, the set of windowless bedrooms in a row leave some attendants saying they feel like they're in a coffin.
Used for long haul flights, the staircase leads crew members upwards into sleeping quarters fitted with mattresses, pillows and curtains offering a small amount of privacy.
The beds are even fitted with seat belts - meaning you won't go tumbling onto a friend's mattress should you hit a patch of turbulence.
The hidden staircase is hardly ever spotted by passengers, as it's disguised behind a security-coded door.
While the size and position of the bedroom area varies on each flight, the crew's sleeping quarters are usually positioned behind the cockpit area, above first class.
Some entrances to the sleeping areas are disguised as an overhead bin.
Boeing 777's have between six and 10 beds, with each one coming with storage areas for a crew member's belongings.
Some lucky attendants might even bag themselves a TV with their bed.
A British Airways crew member spoke to the MailOnline Travel about sleeping in the onboard beds.
She said: "On the Boeing 747's it's all bunk beds and on the 777 it feels like you're in a coffin.
"They are cramped but you can make it comfortable if you get a blanket or pillow.
"I always take my own pyjamas and I make a little bed up."
