Travel by air presents a number of challenges where unaccompanied children are concerned. One reason is that so many more children travel solo by plane than by any other means. Another is that, while there are age guidelines and restrictions, maturity levels can differ dramatically among children. It is not just whether a child likes to fly. Some children are fearful of not being with their parents. Others may not want to travel to the place where they happen to be going. The Independent Traveler, Inc., an organization that provides travel advice, reported on its website the case of an 11-year-old boy whose father saw him board the plane that was to take him to his grandparents’ home. After the father left, the boy got off the plane, left the airport, and walked 30 miles back to his house. Clearly he did not want to take this trip. Yet his behavior is surprising in view of his age.
