The Prince and Princess of Wales broke the rules around royal travel when their eldest children, Prince George and Princess Charlotte, joined them on their overseas tours.
It’s long been an unwritten rule that two heirs shouldn’t travel on the same flight but Prince William and Prince George travelled together to Australia in 2014, Canada in 2016 and Germany and Poland in 2017.
William reportedly asked permission from the late Queen for George to accompany him and Kate on their visit to Australia and New Zealand.

But the rules could be about to change for 11-year-old George in the next year, and he may no longer travel with his parents and younger siblings, Princess Charlotte, nine, and Prince Louis, six.
Former royal pilot Graham Laurie confirmed on an episode of HELLO!’s A Right Royal Podcast last year when William turned 12, he began travelling in a different aircraft to his family.
Speaking about transporting Charles, Diana, William and Harry on family trips, Graham recalled: “The ones I did [holiday flights] mainly were the ones when the Wales’ went to the Mediterranean.
“But interestingly, we flew all four: the Prince, the Princess, Prince William and Prince Harry, up until when 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.
“Nowadays, for instance, the King can’t fly with the Prince of Wales.”
