When booking an unaccompanied minor service with United Airlines, the United Airline Unaccompanied Minor Fee is, of course, applicable. An unaccompanied minor travelling alone is charged $150 (one-way) by the airline, regardless of the destination. For a one-way trip, you must pay US$300, and for a roundtrip for four unaccompanied minors, you must pay US$600. Additionally, parents and guardians have the option to pay the service charge at the time of booking or prior to departure at the airport.
