If a minor is traveling without their parents (alone, in a group, with other relatives, etc.), they will need a Minor Travel Consent Form. These forms grant parental permission for the minor to travel.

A child consent form for Delta (and most international carriers) is a legal document used when a minor is traveling with only one parent, a guardian, or another adult who is not their legal parent. While Delta doesn't have a proprietary form, they require a notarized letter of consent signed by the non-traveling parent(s). This letter must include the child's name, the travel dates, the destination, and the contact information for the absent parent. This is particularly critical for international travel, where foreign border officials (such as those in South Africa or Mexico) may demand proof of custody or consent to prevent international parental child abduction. For children traveling alone, Delta has a formal Unaccompanied Minor (UMNR) Program for ages 5–14, which requires a specific "service form" to be completed during booking and check-in, identifying exactly who will be dropping off and picking up the child with a valid government-issued photo ID.
