Prince William and his eldest son, Prince George, were spotted on a commercial British Airways flight to Barcelona. The two were traveling to watch Aston Villa play FC Barcelona in the Champions League. Photos and videos showed father and son dressed casually and carrying their own luggage, accompanied by unobtrusive security personnel. Instead of a private jet, the trip looked decidedly ordinary — and that is precisely what made it noteworthy.

Prince William and Prince George Flew Together to the Champions League

According to reports, passengers noticed the two royals on the flight to Spain. There was no grand entrance on board — just a low-key journey much like that of other travelers. For William, a passionate Aston Villa fan, the trip also offered a chance to spend time with his son away from official engagements. George is now 13 years old. This immediately raised a question: Were the Prince of Wales and his eldest son even allowed to be on the same plane?

Heirs to The Throne Should Travel Separately Starting at Around Age Twelve

This stems from a long-standing convention of the monarchy. According to this practice, direct heirs to the throne should, whenever possible, not travel together on the same plane. The reason is pragmatic: in the event of an accident, several future monarchs could otherwise be affected at the same time. William is next in line after King Charles III, followed by George, Princess Charlotte, and Prince Louis. The separation traditionally applies once the younger heir reaches approximately the age of twelve. George passed this milestone in July 2025.

King Charles Can Grant Exceptions For Flights

The rule is not a law, but a tradition. Exceptions can therefore be granted. Similar joint flights have occurred in the past, especially when the children were younger. In principle, King Charles could have given his approval for this trip, though no such permission has been publicly confirmed. Formally, the joint commercial flight stands out, but it does not necessarily constitute a violation of the rules.
