Prince George is to be seperated from Prince William when he turns 12 this month due to one royal tradition.
The rule is in place to protect the British monarchy and reads that Princess Charlotte and Prince George will no longer be allowed to travel together.
It prohibits Prince George from sharing the same aircraft as Prince William or his sister, unless under very specific circumstances or with permission from King Charles III.
This rule has been in place for decades in order to protect the line of succession if an accident was to happen.
The same rule is in place for Prince William and his father, King Charles III who only travelled together in William’s childhood.
Graham Laurie, a former royal pilot for King Charles, said: “We flew all four: the Prince, the Princess, Prince William, and Prince Harry, up until Prince William was 12 years old.
“After that, he had to have a separate aircraft, and we could only fly all four together when they were young with the written permission of Her Majesty.”
