Prince William: Future King always travels with this particular item of luggage

It’s understood Prince George, seven, and Princess Charlotte, five, also have a miniature version of the suitcase.

However, William’s brother Prince Harry, 35, and his wife Meghan Markle, 38, are not known to favour the luggage company.

The royals keep their luggage separate by labelling them with coloured luggage tags.

Prince William has a red luggage tag, while Kate has a yellow one.
