While this rule has rarely been enforced strictly in recent decades, the intention remains. George, as second in line to the throne, is now viewed through a different lens within palace protocol — as someone who must be protected not only as a son, but as a future king.

A precaution rooted in history

The tradition, while not enshrined in law, is underscored by past royal tragedies. Several members of the royal family — including Prince Philip’s sister Princess Cecilie and Queen Elizabeth’s cousin Prince William of Gloucester — died in air crashes during the 20th century.

These sobering reminders reinforce the logic behind separating heirs when travelling. Though modern aviation is far safer today, the symbolism and duty of the Crown still call for such precautions.

It’s worth noting that any continued joint travel between Prince George and his father would require formal consent from King Charles III. And while the family has, at times, opted to fly together in recent years — especially when the children were younger — decisions moving forward are expected to reflect George’s new status.

For now, Prince George remains firmly in childhood, likely unaware of the logistical considerations being made on his behalf. But his 12th birthday quietly marks a shift — a subtle reminder that even for the youngest members of the royal family, duty begins early.
