In airline terminology, a child traveling without an accompanying adult is called an unaccompanied minor, often abbreviated UMNR. This is the standard term used to identify a passenger who requires special supervision from check-in to arrival, with staff guiding them through security, boarding, and the handoff to a designated guardian at the destination. Using a precise, official term ensures everyone involved understands the exact procedures that must be followed.

The other phrases aren’t standard industry terms, so they wouldn’t signal the airline’s required UMNR handling or readiness to provide the appropriate supervision. That’s why this term is the best choice.
