What is the air to the throne?

The "air to the throne" refers to the individual who is first in line to inherit a monarchy's throne. This position is typically held by the monarch's eldest child or closest relative, depending on the rules of succession in a particular royal family. The heir often undergoes training and preparation to assume royal duties and responsibilities once they inherit the crown. The title signifies not only a claim to power but also the expectations and obligations associated with being a future leader.
