Have you ever been so caught up in daily life that you miss something right in front of you? I can definitely relate. There have been times when I’ve searched for my phone while it was in my hand. Recently, after a flight, I came across some fascinating information about airplane features that I never even knew existed: the triangle stickers above your seat.
The Curious Question That Sparked the Discovery

It all started when my brother casually asked where I had sat on the plane. This simple question set me on a journey of discovery, as I realized something I’d overlooked during my many flights—the black or red triangle stickers above the windows. I’d never really paid attention to them, but once I noticed, I became curious about their significance.
What Do the Triangle Stickers Actually Mean?
My curiosity led me to some online research, and I soon discovered that these triangle stickers have an important purpose. Though most passengers overlook them, they are actually useful tools for pilots and flight attendants. These stickers are carefully positioned to align with the airplane’s wings, with one pointing to the front and the other to the back. They are essential when it comes to wing inspections, as they help the crew quickly identify the correct location for checking the moving parts of the wing, like flaps and slats.
How These Stickers Help Passengers Too

It turns out that these stickers have an added benefit for passengers. If you’re someone who experiences motion sickness, sitting near the wings can help reduce the sensation of movement. The wings represent the center of gravity on the plane, much like sitting in the middle of a seesaw, where the motion is least noticeable. So, if you spot one of these triangles, choosing a seat nearby could offer a smoother, less turbulent flight.
Next Time You Fly, Pay Attention to the Triangles
Next time you board a plane and spot one of these triangle stickers above your seat, you’ll know exactly what they signify. They’re not just decoration—they’re there to guide flight crew and, in turn, to make the flight experience smoother and safer for passengers as well. Have you ever noticed them before?
