The young royals have officially kicked off their 11-day tour of Canada and the US.
Greeted by the Canadian High Commissioner to the United Kingdon, the Cambridges arrived at London's Heathrow Airport to begin their first overseas tour as a married couple.
The two were all smiles as they boarded a Royal Canadian Air Force plane.
This trans-Atlantic flight is especially exciting for Kate as this is her first time travelling to North America.
The Duchess dressed for the occassion in a fitted navy dress and jacket reminiscent of the military-inspired ensemble she wore to honour Irish soldiers earlier this month.
William and Kate are scheduled to take part in the Canada Day celebrations in Ottawa soon after landing.
