In one week, a time-honored royal tradition will quietly change Prince George’s life—separating him from his siblings and parents as he steps further into his future role as heir.

A Royal Rule to Protect the Line of Succession

When Prince George turns 12 on July 22, a long-standing royal protocol will take effect: the young heir will no longer be permitted to travel on the same aircraft as his parents or younger siblings without explicit permission from the reigning monarch. The practice ensures that at least one direct heir remains safe in the event of an unforeseen tragedy—maintaining stability for the monarchy.

This tradition mirrors what happened with his father, Prince William, who was also required to fly separately from Prince Charles and Prince Harry after his 12th birthday.

A Young Heir in the Public Eye

In recent months, George has been seen more frequently alongside his family. He attended the Euro 2024 final with William, watched Spain defeat England, and joined Kate Middleton for her annual Christmas carol concert. He appeared on Buckingham Palace’s balcony during Trooping the Colour and met World War II veterans with his father. Just days ago, he sat in the royal box at Wimbledon with Princess Charlotte and his parents, watching Jannik Sinner triumph over Carlos Alcaraz.

These appearances hint at a gradual, intentional preparation for his future responsibilities.

A Practice Rooted in Royal History

The rule of separating heirs has precedent. King Charles’s former pilot, Graham Laurie, once explained:

“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.”

This safeguard has long been part of royal planning, ensuring continuity even during uncertain times.

The Monarch’s Discretion

While the tradition is respected, it is not absolute. The reigning monarch—currently King Charles III—may grant exceptions if necessary. Should William and George wish to travel together on the same flight, they must first seek his approval.

This measure, though rarely discussed publicly, underscores the monarchy’s commitment to protecting the line of succession. It’s a quiet reminder that even in moments of family closeness, royal duty—and the future of the crown—remains paramount.
