There are many rules and royal precedents set for senior members of the British royal family when it comes to air travel.
One of the most famous is that two heirs are not to travel in the same aeroplane should an unfortunate accident occur, to prevent leaving England without a monarch.

According to former British Airways air hostess and ex-Love Islander, Helena Ford, who assisted the royal couple before heading into the famous villa in Majorca, the royals aren't allowed to sit in the highest cabin on the flight.
She told Made in Chelsea alumni, Olivia Bentley, on the Private Parts podcast: "I think there is a thing in place where they can't fly in the highest cabin, so if there's a first class, they have to sit in business, and if there isn't a first class, they have to sit in Traveller Plus.
"So I've had Boris Johnson on a flight in Traveller Plus before. They can't sit in the highest cabin. As for the reason, Helena added: "I don't know, but they all have fake names."
Helena explained that when William and Kate were on her flight, they sat in business class, as there was a first class on that day, and that other than the royals, the rest of business class was sat in by members of their security team.

British Airways is the go-to airline the royals travel with and even has a special place in Kate's heart, as both her parents met while working for the company.
Carole is a former Air Hostess; meanwhile, Michael was working as an aircraft dispatcher.
All the details on royal travel
In an interview for HELLO!'s A Right Royal Podcast, His Majesty The King's former pilot Graham Laurie revealed that Prince William flew with his parents and brother, Prince Harry, until his 12th birthday in 1994.
"After that, he had to have a separate aircraft," Laurie remembered. The pilot also pointed out that exceptions were only made when the late Queen granted written permission for Prince William to fly with his father.
But in recent years, the Wales family have been travelling together because it isn't economical or cost-effective to use two aircraft every time they travel.

But as we've seen in recent years, the Prince and Princess of Wales do travel together with their children for tours, engagements and privately, Stacey continues. "It would not be cost-effective, practical or economically friendly for immediate family members to travel on different aircraft."
Other royal rules include all members of the family having clearly monogrammed luggage inside, which is a black outfit, in case the worst happens.
This protocol stems from when the Queen returned to the UK after hearing of her father’s death in 1952 and had to wait for staff to provide mourning attire before she left the plane.
