On wide-bodied airplanes, there are hidden spaces that are off limits to passengers.

Recently, CNN dived in, giving a view into Crew Rest Compartments, or areas where crew can take breaks throughout the flight. On newer airplanes like Boeing 787s or Airbus A350s, they tend to be above the main cabin, but in older planes they’re often in the cargo hold or main cabin.

These cabins, which look similar to a capsule hotel, typically come in twos; there’s one for the pilots which sits near the cockpit, and another for cabin crew. The one for the pilots includes two bunks and a recliner seat, while the cabin crew rest compartment contains more bunks.

The hidden compartments have restrictions set by the Federal Aviation Administration that mandate the areas have little intrusive noise, odors or vibrations, so crew can rest well.
