Yes, American Airlines permits minors to travel alone. However, as per their policies, solo children who are between 5 and 14 years old are required to use American Airlines Unaccompanied Minor service. Moreover, this service provides continuous assistance to the kids, starting from check-in until they reach their destination. Other than that, young flyers between 15-17 can travel independently yet parents have the choice to obtain UM service for the safe journey.
