A palace spokesperson told OK! Online that they were on a "private family holiday".
It is believed they are visiting Kate's relatives, the Daily Mail reports.
The Cessna Citation X jet is thought to be the same one they borrowed in March for their ski holiday in Courchevel, when they took their children on their first family holiday.
Earlier this year, it was reported that one luxury hotel in France told Kate Middleton, Prince William and Prince Harry that there was no room at the inn (literally) when they tried to book rooms.
The three royals were travelling to France for the 100th anniversary of the Battle of the Somme on 30 June and wanted to stay at the Hotel Marotte - the only five-star hotel in the Amiens area.
Speaking to The Local, a hotel receptionist said: "Unfortunately it is true. We have to decline many many people for the 30 June."
