As provided in the AirTran Contract of Carriage, children under the age of 12 traveling without an accompanying adult are not permitted to fly on any international flight.
In Mexico, a minor is considered any child under the age of 18.
It is recommended that minors traveling without both parents/legal guardians have a notarized affidavit (letter of permission) signed by the absent parents/legal guardians authorizing the child to travel.
Copies of both parents’/legal guardians’ identifications are recommended.
The minor’s original birth certificate or a certified copy of the birth certificate is recommended.
