As a result, she has an array of tips and tricks up her sleeve when it comes to flying.
One thing she is particularly renowned for is her impeccable style, always looking her best no matter where in the world she is.
However, it seems a lot of thought goes into ensuring not a hair is out of place.
Alongside travelling with her own stylist and hairdresser, she also has a strict set of fashion rules when jetting off.
Royal travel: Kate Middleton has strict fashion rules when travelling
While the average traveller may simply fold their clothes into a suitcase, things are a little different for the wife of Prince William.
When travelling with her many high-end dresses, each item is packed within its own garment bag.
These are often transported on board by hand.
In some situations, it has even been reported each dress is not packed into the hold but instead given its own VIP seat onboard the aeroplane.
She says she has “been on a plane where Kate’s dresses had their own seat to make sure they were kept flat”.
The journalist continued: “They are not going to be shoved in the hole just to be squashed by everyone else’s.”
In another interview, Ms Andrews explained this happens most often on private jets.
The cost of transporting the Royal Family
“When it’s small charter planes and there is space, her clothes do have their own row,” the expert said.
“This happened on a private plane we took in India to Kasaranga National Park.
“Natasha Archer [Kate’s stylist] brought all her dresses on and laid them over an entire row.”
However, this is not necessarily the case when Kate travels commercially due to limited space.
For the clothes which do end up being packed, Kate also has a handy trick up her sleeve when her wardrobe does need to be tucked into a suitcase.
The solution comes in the form of “wrinkle-free” fabrics.
“All the Duchess or her ‘people’ have to do is familiarise themselves with the best wrinkle-free fabrics,” former creative director of Mulberry, Scott Henshall, told MailOnline.
“Typically synthetic fabrics such as polyester, nylon, acrylic and olefin have a natural resistance to wrinkles and a greater stability since they do not absorb water as efficiently.”
