The family were on their way to Balmoral Castle to join the King for the traditional Royal summer break. Princess Catherine's low-key choice of an economy class flight to Inverness Airport, rather than a private jet or helicopter, highlighted her hands-on parenting style as she retrieved her daughter's iPad during the flight.

Another passenger discreetly documented the trip, sharing that the atmosphere on board was calm despite the excitement of having the Royals on board. Upon arrival Princess Catherine was seen holding Charlotte's hand, while Louis followed, both children carrying overnight bags.

The trip was particularly meaningful for Princess Catherine, who is currently facing a number of health challenges that have forced her to step back from most royal duties. The Balmoral gathering is seen as a chance for recovery for Princess Catherine and her family, especially after a challenging year of personal and family struggles.

The estate holds deep sentimental value for Prince William and Princess Catherine, as it is where their love blossomed during their college years. There is also ongoing speculation about a potential visit by Prince Harry and Meghan Markle.

The trip could provide a rare opportunity for a Royal reconciliation. Overall, the trip represents a moment of reflection, healing and quality time for the royal family amid changing tides.
