How Prince William is breaking a royal rule by flying with son George

Prince William has drawn scrutiny for travelling on the same aircraft as his 13-year-old son, Prince George, despite a long-standing royal convention that heirs to the British throne should fly separately to protect the line of succession. The two reportedly took the same British Airways flight to Barcelona last week and travelled together on the return journey as well.The Prince of Wales and his eldest son reportedly flew together on a scheduled British Airways flight to Barcelona last week during George's half-term break from Eton College.

The two also travelled on the same aircraft on their return journey, according to a report by the Daily Mail.The father and son were in Spain to watch a Champions League match between Barcelona and their favourite team, Aston Villa, at the Spotify Camp Nou stadium. Their decision to take a commercial flight rather than a private jet reportedly drew attention from fellow passengers.However, the concern centres on the royal convention that senior members of the line of succession should avoid travelling together.
