Why Some Airplane Seats Have a Tiny Triangle Above Them

Ever noticed a little triangle above certain airplane windows and wondered what it’s for?

You’re not imagining things — it’s real. 

That small black triangle (sometimes white or gray) seems random, but it actually serves a very specific purpose. And no, it’s not just for decoration.

In fact, if you’re sitting beneath one, you’re in a pretty important spot — and now you’ll know exactly why.

The Most Useful Seat on the Plane — According to Flight Attendants

That little triangle marks the best vantage point for checking the wings of the aircraft.

Flight attendants use it as a visual cue when they need to inspect the plane’s flaps, slats, ailerons, or even check for ice buildup.

Especially in-flight, if there’s a mechanical issue or concern, these seats provide the clearest, most direct view of the wing’s surface.

So when you’re flying and see the crew crouch by your row and look out the window — yep, they’re using your seat’s view for a safety check.

Why Do Airlines Mark These Seats?

It’s all about efficiency and safety. 

Rather than guess which window gives the best look at the wing, airlines mark those windows with a triangle. 

It saves time, especially in situations where seconds count.

And sometimes, during flight training or emergency drills, staff use those triangle seats as quick-reference spots to visually confirm what’s happening outside.

Bonus Perk: The Wing View

Ironically, some of the best “Instagram-worthy” wing shots come from these exact seats. 

So not only are you sitting in a key safety location, you’re also in a prime photo zone. Double win.

If you’re someone who loves capturing that golden hour glow bouncing off the wing, aim for the seats near the triangle.

Final Thought

Next time you fly, look up. That little triangle isn’t random — it’s a tiny symbol of how detailed aviation safety really is.

And if you find yourself sitting under one, know that you’ve got one of the most important seats on the aircraft. Quietly useful. Purposefully placed.
