9 Hidden Airplane Features You Had No Idea Existed
Keep an eye out for these airplane features on your next flight.
Hidden airplane features
When you travel on an airplane (or if you’re feeling fancy, an aeroplane), your main focus is most likely getting to your destination and being comfortable enough to sleep. But if you take a look around, you might notice a few airplane features that you never knew were there. There’s a purpose to everything when it comes to air travel, including the roundness of airplane windows and the existence of rear-facing airplane seats. And let’s not get even get started on what happens when you flush an airplane toilet. Read on to discover where these airplane features hide and the purpose they serve.
The magic button for extra room
Did you manage to snag an aisle seat? Not only can you get up without crawling over people, but you can also make your seat extra roomy at the push of a button, thanks to one of the coolest secret airplane features. Reach under the armrest closest to the aisle and feel around near the hinge. You should find a button, which will instantly let you swing the armrest up when you push it. Once it’s in line with your seat back, it won’t dig into your side anymore, and you can move your legs around without hitting anything. Since it’s always so cold on airplanes, this will even give you more room to wrap yourself up in a blanket.
The hidden handrail
We’re willing to bet you hate it when people aggressively grab your seat on the way to the bathroom. Once it’s your turn to make your way down the aisle, though, you realize you have no choice but to follow suit—or do you? Flight attendants don’t just touch the ceiling for fun when they walk; the bottom of the overhead compartment has a scalloped area that provides a better grip when walking down a moving airplane. Next time you need to get up, reach above for balance, and don’t make these other airplane travel mistakes.
The secret sleeping area
A long-haul flight is hard enough on passengers, but imagine being a pilot or flight attendant trying to make it through a 14-hour workday. It’s an exhausting job, so some planes, like Boeing 777 and 787 planes, have secret passageways that let staff get some decent shut-eye, according to Insider. A locked door near the front of the plane or a door posing as an overhead bin hides the entrance to a set of beds, kept private with thick curtains.
The hooks on the wings
If you peek out the window to an Airbus’s wing, you can spot yellow bumps with holes in the middle on an otherwise smooth, white surface. If there’s an emergency water landing, the wings will be very slippery for passengers trying to get to the inflatable slide that will have deployed. To help travelers get off without falling, these easy-to-miss airplane features let the cabin crew slip a rope through one hook and fasten it to the next, according to pilot and YouTuber “Captain” Joe. Passengers could hold on to the rope while on the wing to make it away from the plane safely. Next, find out how high airplanes really fly.
The triangle above the window
Scan the wall of your plane; above four windows, you’ll see a black triangle. Each one lines up with the edge of the airplane’s wing, according to “Captain” Joe. If flight attendants need to check the airplane’s slats or flaps—the moving parts on a wing—they’ll know exactly where to go for the best view. If you’re getting motion sick on a plane, you might want to see if you can move to a seat between the triangles. The wings are the plane’s center of gravity, so sitting between them would give you the smoothest ride. For more information about airplane features, learn how in-flight Wi-Fi works.
The holes in the windows
Look closely at an airplane window, and you’ll spot something weird: a little hole in the bottom. Take an even closer look, and you’ll realize that, unlike other windows, this one is made of three panes, and the hole is in the middle one. The quirk is there to protect against the pressure drop of flying high into the atmosphere. As a plane ascends, the pressure outside drops massively, but the cabin is designed to stay at a comfortable pressure. That leaves a big difference in pressure inside and outside the plane. The outside window takes on most of that pressure, and the hole in the middle pane helps balance the pressure difference. The inner window is just to protect the middle one.
The ashtrays in the bathrooms
The ashtrays in the bathroom aren’t really hidden, but if you’ve seen them, you’ve probably wondered why planes (including newer planes) still have them. Even though smoking is banned when you’re on an airplane, it’s still common practice to install them. In the event that a smoker breaks the rules and decides to smoke in the bathroom, they will dispose of their cigarette in the ashtray rather than throwing it in the trash and potentially causing a fire. Snuffing out your cigarette before you board is just one rule to follow. Another: Turn your phone on airplane mode.
The hidden handcuffs
If passengers are getting unruly, flight attendants have the right to restrain them. They might use typical cop-style cuffs, but most will use plastic restraints similar to zip ties, according to Express.

The outside-bathroom locks
The bathroom isn’t as private as it may seem. Even though you lock the door from the inside, there is a button located underneath the “lavatory” sign outside the bathroom door. This button will allow flight attendants to unlock the door from the outside in case of an emergency. For more airplane trivia, learn what those weird noises on airplanes are all about.
