Inspired by the Kentucky colonels and other honorary title designations, Smith decided to make particularly valued passengers "admirals" of the "Flagship fleet" (AA called its aircraft "Flagships" at the time). The list of Admirals included many celebrities, politicians, and other VIPs, as well as more "ordinary" customers who had been particularly loyal to the airline.
