You may at some point have been sat on a long haul flight wondering - perhaps as you try to drift off yourself - how the crew members manage to stay awake through flights that can sometimes extend to almost a full day.
Well, you'll be glad to learn that they don't have to - they simply head to a part of the plane that you're not allowed to go into and get their heads down for a short while.
Now, a travel enthusiast called Zach Griff - who is an analyst for travel website The Points Guy - has offered passengers a glimpse behind the scenes of modern aircraft and shown where this secret breakout bedroom is hidden.
On his Instagram, he shared a clip from the inside of an American Airlines 787 Dreamliner that has an upstairs area for the crew to head to on their time off.
It's pretty poky, but it's got some beds on the floor and a few other creature comforts, too.
Zach says that he's travelled to 55 countries and racked up more than 200,000 air miles during his career - he describes himself as a full-time traveller - so he's well placed to know the inner workings of an aeroplane.
As we've mentioned, this place is off limits to us common folks, so you'd never even know that it existed if it wasn't shown to us here.
Speaking to the Metro, Zach explained: "The largest airline in the world, American Airlines, just introduced a brand-new Boeing 787-8 Dreamliner to its fleet.
"Before the plane started flying passengers, I got a behind-the-scenes tour of the entire aircraft, from the cockpit all the way to the crew rest.
"The crew rest is easily the coolest part of the entire plane. It's completely off-limits to passengers, and only certain crew can use it during flight.
"It's also really interesting that it's located one level above passengers - so no one really knows about it.
"I thought the variety of items in the crew rest area was fascinating. There are smoke detectors, fire extinguishers, flashlights and portable oxygen containers for use in an emergency.
"There are also comfort items, such as power outlets, a small mirror, coat hooks and a phone to call the other flight attendant stations."
He added: "One thing to note is that it's a really tight squeeze up there.
"There's very little room to move around and I almost hit my head multiple times! But the good news is that the beds are actually quite comfortable."
There you have it. While you're snoozing away on your next flight - whenever that might actually be - there could be a member of staff getting some shut-eye right above your head.
