American Airlines says it will charge a $150 fee each way for minors between 12 and 14 who fly alone. The change starts Sept. 3. Currently, American charges a fee on top of the regular fare for unaccompanied minors between 5 and 11.
Young adults may travel alone on American Airlines, though they are required to use the unaccompanied minor service if they are younger than 15 years old. A young adult who is at least 15 may be booked as an unaccompanied minor, but you also can book him as a regular passenger. You cannot buy a young adult a ticket without an adult if their travel requires a connection to another airline.
