Prince George has just seven days before he’ll be forced to be separated from Prince William and Princess Charlotte

Prince George, the eldest son of Prince William and Kate Middleton, turns 12 on 22 July. With this milestone, a long-standing royal tradition will come into effect, setting him apart from his parents and siblings.

As the heir presumptive after his father, Prince George is being gradually prepared for future royal duties. His increasing public appearances—like attending the Euros final, Trooping the Colour, and Wimbledon—highlight this transition.

The royal family is mindful that events can change quickly. Both George’s great-grandmother, Queen Elizabeth II, and great-great-grandfather, King George VI, unexpectedly assumed the throne at young ages.

To ensure the monarchy’s continuity, specific protocols are put in place for heirs. One such rule requires that two immediate heirs not travel together, aiming to protect the line of succession in case of accidents.

This means that from age 12, George will no longer be allowed to fly with his parents or siblings. It’s a precaution also taken with Prince William, who had to travel separately from age 12.

Former royal pilot Graham Laurie explained that when William reached that age, he flew separately from his family unless written permission was granted by the monarch.

Though this travel rule isn’t formally documented, it’s strongly encouraged. The tragic deaths of several royals in plane crashes—like Princess Cecilie, Prince George (Elizabeth’s uncle), and Prince William of Gloucester—have influenced this tradition.

If Prince William and George wish to fly together in the future, they must request King Charles’s approval to override the usual protocol.
