A royal protocol will require Prince George to travel separately from his sister, Princess Charlotte, and their father, Prince William, once he turns 12 next July. This rule, aimed at safeguarding the monarchy's line of succession, reflects similar restrictions that Prince William experienced at the same age. The rationale behind the protocol is to mitigate risks associated with travel, ensuring that key heirs do not travel together in case of an accident. King Charles's former pilot, Graham Laurie, highlighted that after Prince William turned 12, he had to fly separately, and this practice may soon be enforced for George. If the family wishes to travel together, they will need permission from King Charles as the monarch. Although plane crashes are rare, historical incidents have raised concern about the potential loss of multiple heirs in a single accident.
