In order to preserve the line of succession, two direct heirs — like Prince William and Prince George — in line for the throne are technically not allowed to travel by plane together.
In the UK, it is against the royal protocol that two heirs to the throne travel together, and this is a rule that all royal households across Europe also follow to preserve the survival of the monarchy. However, some British royals have been spotted breaking this rule in the past.
He told The Sun: "There is a strong constitutional reason that William and Harry do not fly together - and that is to do with the line of succession.
This includes an Airbus Voyager of the Royal Air Force (RAF), No. 10 Squadron, and the King's Helicopter Flight, which forms part of the royal household. Civil aircraft and scheduled commercial flights are also utilised.
The royal family uses the RAF VIP Voyager jet to travel around the world in an official capacity. The specially designed plane is available to the royal family and British government officials. While off-duty, members of the royal family have been known to use both private planes and budget airlines.
Finally, Prince Charles was able to start his jet flying on 19 March 1971 and Sir Richard remembers the time as being quite an easy job as the Prince was so competent.
Once Prince George turns 12, the Queen can no longer override protocol, and he and Prince William literally won't be able to travel in a plane together—no exceptions. This is also the case for William and Prince Charles, who travel separately, as well as Charles and his mother the Queen.
Because Harry arrived late – and without wife Meghan Markle – some reports speculated that ongoing tension with the royal family prompted the Duke of Sussex to travel solo. However, sources told Page Six that Charles, 73, specifically asked William, 40, to fly up early and attend the Privy Council meeting in his place.
"Unwilling to waste more time, William ordered the RAF jet to take off at 2.39 pm. Harry was left to hire his own plane and make the journey alone.
Unless you're a head of state, no, there are unlikely to be any extra flights.
But until 2011, any daughter born to the Duke and Duchess of Cambridge would not have enjoyed an equal right to inherit the British throne. Rules dating back centuries decree that the crown passes to the eldest son and is only bestowed on a daughter when there are no sons.
According to UK media, Queen Elizabeth has overridden the rule for children while they are young. However, once Prince George turns 12 years old, the Queen will not be able to make exceptions and he must travel separately from his father.
It has been reported that the Queen and Prince Phillip didn't share a bed because of a tradition followed by the upper classes. Not only did the monarch and her husband not share a bed, but it's also believed that they each had separate bedrooms altogether.
Perhaps the most oft-transgressed maxim is touching a member of the royal family in a manner that goes beyond a formal handshake—a guideline that likely dates back to the Middle Ages, when, as the British historian Kate Williams has noted, “monarchs were divinely appointed to rule by God, so they were kind of seen as ...
As an old tradition dictates, royal couples never share the same bed or bedroom, allowing them to move freely while asleep.
Prince Harry has described how he “can't ever get out” of the royal family, but he does not believe it will ever be possible for him and the Duchess of Sussex to return to the UK as working royals.
For Prince Harry to inherit the throne, he would have to move to first position in the line of succession. This line is the formal order in which members of the royal family will inherit the throne and is determined by blood proximity to the monarch.
That toxic dynamic, according to Harry, catalyzed their departure: The Sussexes were crumbling under incessant negative media coverage that included an intimate letter between Meghan and her estranged father published in The Daily Mail. (The duchess even began to have suicidal thoughts.)
And, there's one more big rule they must follow as well, and that is to avoid ever flying on the same plane together. As Business Insider reported, it is an unwritten rule that the senior members of the royal family should avoid all traveling together in one plane in the extreme off-chance that tragedy strikes.
William is a skilled pilot, completing his Royal Air Force training in 2010 and later going on to serve as a search and rescue pilot for years, often flying in harsh weather conditions.
While Prince George and Prince Louis are likely to receive dukedoms when they are older, there's a royal rule which means that Princess Charlotte won't receive a Duchess title from the monarch.
Harry later qualified as an Apache helicopter commander in 2013 after three years of training. While on a five-month tour in Afghanistan, he served as a co-pilot gunner - sharing flying duties and taking control of the weapons of the two-man Apache.
5 The Airbus A320-232 Used TO Hold 180 People But Now Accommodates Around 26 People. King Charles spends the most money on his travel by far, and the private jet that he prefers is truly fit for a king. When King Charles and Camilla traveled to the states, they relaxed on the Airbus A320-232.
In April 2008, William graduated from Royal Air Force College Cranwell, joining the RAF Search and Rescue Force in early 2009. He served as a full-time pilot with the East Anglian Air Ambulance for two years, starting in July 2015.
