French minors under 18 years of age must travel with: (i) a valid passport or (ii) a valid National ID (in the event that their destination countries do not require passports).
The family register is NOT a valid identity document for French citizens who are minors. Therefore, minors are not permitted to fly on planes, even within continental France, without a National ID.
From January 15, for international flights and with a valid French ID Card for international travelers or valid French Passport, any unaccompanied minor must carry a travel permit. This document should be signed by both parents or legal guardians and be supported by a photocopy of a valid ID (or one that has been expired for less than 5 years) of said parents or legal guardians. For further information, contact the local French authority responsible.
