Lufthansa Unaccompanied Minor Fee:- There are many differences in airline policies regarding the minimum age for children flying alone and escort services for unaccompanied minors. Nearly all other airlines, excluding the major low-cost carriers, provide a special service to look after kids traveling alone. Assisting with boarding, keeping an eye on your child during the flight, and having airline personnel wait for you to pick up your child at the destination airport are all included in this.
