Yes, a minor can travel internationally without parents, but they must carry extensive documentation to satisfy both airlines and immigration officials. The most critical document is a Child Travel Consent Form (also known as a Letter of Consent), which must be signed by both parents or legal guardians and ideally notarized. This form outlines the child's travel details, the identity of the person supervising them (or a note if they are traveling alone as an "Unaccompanied Minor"), and contact information for the parents. Additionally, the minor must have their own valid passport and, in many cases, a copy of their birth certificate to prove their relationship to the consenting adults. If a child is traveling with only one parent, the non-traveling parent's consent is usually required to prevent international parental abduction. Airlines have specific Unaccompanied Minor (UM) programs for children typically aged 5 to 14, where a fee is paid for a staff member to escort the child from gate to gate, but these services must be booked in advance.
