Air France allows unaccompanied minors between the ages of 4 and 17 to fly alone using their Kids Solo service. Children flying alone will be accompanied by an airline staff member who is responsible for supervising them at all times. Parents must inform the airline that their child is traveling alone and complete necessary paperwork in advance or at check-in. Regulations specify that a child not accompanied by someone over 18 is considered an unaccompanied minor, even if traveling with a parent under 18, and that unaccompanied minors will not be allowed in airport lounges for supervision reasons.
