Prince William and Princess Catherine have yet to abide by this regulation concerning the future king, but this could alter as the young royal reaches 12 years of age on July 22, 2025.
You might be wondering why this change is anticipated.
Well, at the age of 12, Prince William himself commenced flying independently from his father, King Charles.
The rationale behind this protocol is primarily centered on security concerns.
The preservation of the royal lineage in case of unforeseen events is a paramount consideration.
A correspondent from Hello!
magazine, Danielle Stacey, shed light on the origin of this protocol, which dates back several decades when air travel was notably less reliable.
It has become customary for Prince William and Kate Middleton to journey with their three children – Prince George (10), Princess Charlotte (8), and Prince Louis (5).
Nonetheless, it is anticipated that family excursions via airplane will soon undergo a transformation in about two years.
The royal protocol discourages the simultaneous presence of two heirs on the same flight.
Consequently, it is expected that Prince William and his eldest son, Prince George, will undertake separate travels.
Despite the existing practice, which suggests that Prince William and Prince George may not travel together once the latter turns 12, any deviation from this guideline would not mark the first instance of the royal family flouting protocol.
Undoubtedly, one thing remains evident: Prince George is swiftly maturing.
