Flight attendant finally reveals what it means if your plane seat has a black triangle next to it

If you’re a frequent flyer - or just a very observant one - you might have noticed that some plane seats are different to others.

You might have bagged a window seat, only to discover that above the window is a small black triangle.

It’s one of those things that we tend to just accept without ever finding out what it means but one flight attendant has lifted the lid on the hidden meaning behind the symbol.

A cabin crew member for Philippines-based airline, Cebu Pacific, has shared the “secrets” of aircrafts, revealing what the black triangle means.

Henny Joyce Lim posted a video on her TikTok page, @_hennylim_, detailing little-known information.

In the clip, she said: “Number one. Passengers sitting next to the triangles get the best view of the wings.

“If flight crew need to check the wings, these triangles let them know the best vantage points for the slats and flaps outside.

“If you are flying an airline that allows you to choose your own seat, look for one of the triangles in the cabin. Anybody who loves taking window shots or videos will get the best view of the wings from these seats.”

Lim went on to explain that “those triangle-marked seats are either at number 10 or at 18, but it still depends on the type of aircraft one is traveling in”.

The flight attendant ended the video by wishing everyone a safe flight.

This revelation was a shock to a lot of people who took to the comment section to share their reactions.

One user asked: “When there is no seat available, can you sit anywhere? Or when checking in, do they give you a seat like that?”

Lim replied, saying: “Aircraft transferring on seats is not allowed unless authorized by cabin crew.”

Another person posted: “I'm always in the window seat near the wings, same as in the video, but I don't notice the triangle.”

A third wrote: “Who wants to get the best view of the wings? Definitely not me.”

A fourth user added: “Also mainly used for break in points, right?”

Lim responded with: “Yes correct also.”

The TikToker isn’t the first flight attendant to shed some light on the secrets of aircrafts, with another cabin crew member sharing why planes are always so cold.

Jay Robert, a senior international cabin crew member and creator of A Fly Guy’s Cabin Crew Lounge, said: “We know it’s cold … but we also know what happens when the cabin is too warm, and that is a lot harder to manage than a cold cabin.

“I used to work on the largest commercial aircraft in the world that seated over 600 passengers, and one of the things I regularly checked was that the temperature did not exceed 73 degrees (Fahrenheit).

“Sometimes, I would have two or three faintings on a flight, and I would call the front to check the temperature — it was 75 (Fahrenheit) or higher every time.”
