Yes, a minor can travel on their own, but the specific rules and fees depend heavily on their age and the airline's "Unaccompanied Minor" (UM) policy. In 2026, most airlines allow children aged 5 to 11 to fly alone only if the parent pays for a mandatory UM service, where staff escort the child from check-in to the meeting party at the destination. For youths aged 12 to 17, the service is usually optional, and they may fly as "Young Passengers" without an escort. Be aware that ultra-low-cost carriers often do not offer this service at all, prohibiting anyone under 14 or 15 from flying without an adult. Documentation is rigorous: you will need a valid photo ID for the minor, a signed consent form (notarized for international travel), and the specific contact details of the person picking them up. Always check the "minimum age" requirements for your specific airline, as some international carriers mandate a companion for anyone under 16.
