Delta allows unaccompanied minors to travel alone to any national or international destination only if they are booked under the Delta Airlines Unaccompanied Minor policy. This policy is mandatorily applicable to children between the age of 4 to 14 years and optional for youngsters above 15 years. The parents or guardian must provide the name of the unaccompanied minor exactly as occurs on the official ID of the child. The tickets can be booked by calling Delta Airlines executives for the travel. However, an extra fee will be applicable under this policy as additional services are also provided to unaccompanied minors.
