Which type of passenger is an unaccompanied minor?

An unaccompanied minor refers specifically to a child who is traveling alone without any adult supervision. This classification is important for airlines as they have special procedures and regulations in place to ensure the safety and well-being of these young travelers.

In contrast, a child traveling with one parent, a grandparent, or who is under the age of two does not meet the criteria for being classified as an unaccompanied minor. These situations typically involve an adult who is responsible for the child during the journey, which negates the need for special protocols designed for unaccompanied minors. Thus, the correct identification of an unaccompanied minor is a child traveling alone.
