Can minors fly alone in Delta?

Definitely, minors can fly alone on  Delta flights although age determines the applicable rules and regulations. Children between 5 and 14 years old need to use the Delta Unaccompanied Minor service to receive supervision from start to finish of their journey. Teens between 15 and 17 years old can choose to fly independently, but their parents have the choice to use the service if they believe it is needed.
