What is the procedure for unaccompanied minors on Lufthansa? According to Lufthansa Unaccompanied Minor Policy , children between the ages of 5 and 11 are permitted to travel unaccompanied. Unaccompanied minors must have all required documentation in both their destination and origin cities.

The exception would be made if the planned flight was the only one departing from the beginning point or connecting point.
