On these personal trips, as Catherine is on Mustique, they are paid for by the Duchy of Cornwall estate. It depends on how well the estate is doing financially to facilitate flying first on holiday. The profit is now spread between William and family Harry and wife and Charles and Camilla. With two new people joining the outgoings this past few months, I suspect areas are needed to cut back on.
