Flight attendant reveals the true reason behind the missing 13th row on airplanes

A flight attendant has revealed the reason why some airlines exclude the 13th row in the cabin. 

Henny Lim, an air hostess with the Philippines-based airline Cebu Pacific, is known for sharing lesser-known plane secrets. 

In a now-viral TikTok video, she said 'in many cultures, number 13 is associated with bad luck'. 

'That is why most airlines prefer to avoid igniting the superstitions of their customers and have opted to remove the number from the seating plans,' she said.

In the clip, Ms Lim shows how the row numbers jump from 12 to 14 on both sides in the airplane. 

Ms Lim said this is a practice many global airlines follow to 'acknowledge the unlucky superstitions surrounding the number'. 

'The irrational fear of the number is known as "triskaidekaphobia",' she added. 

Lucky and unlucky numbers differ between cultures - for instance number seven is considered lucky in western countries but is considered unlucky in China, Vietnam and Thailand. 

Often the number 17 is deemed unlucky in some countries such as Italy. 

In another video Henny shared the real reason behind the tiny black triangles often seen on plane walls. 

She said the stickers above the middle windows offer the best view of the wings for passengers - but also let flight attendants know the 'best vantage points for the slats and flaps outside'.  

The short clip has since amassed more than 304,000 views, with many admitting they had never noticed the small sticker before.

'Passengers sitting next to the triangles get the best view of the wings,' Henny wrote in the video while recording the inside of an empty plane.
