The Duke and Duchess of Cambridge are reportedly visiting Queen Elizabeth at Balmoral

William, Kate, and their brood flew onboard an economy FlyBe plane. The Cambridges’ budget-friendly travel comes in the wake of criticism Meghan Markle and Prince Harry have faced for taking four private plane flights in less than two weeks. The Duke and Duchess of Sussex are not expected to join their family at the Scottish retreat this weekend because Harry has an engagement on Saturday to attend the Rugby League Challenge Cup Final at Wembley Stadium. Members of the British royal family traditionally visit Balmoral during the summer months. Princess Eugenie has previously revealed that her "Granny" is "the most happy" in the Highlands.

Prior to their trip to Scotland, the Duke and Duchess of Cambridge, who have been visiting Balmoral since their university days, spent time earlier this summer vacationing in Mustique. Prince George rang in his sixth birthday on the private Caribbean island with his parents, siblings and maternal grandparents—Carole and Michael Middleton. With a no-fly zone enforced over Mustique, and the discretion of other guests, the royals are able to relax away from the public eye.
