The Avianca unaccompanied minor policy applies to children aged 5 to 11 who travel domestically or abroad without their parents or legal guardians. You can make a reservation for this service at the Airlines sales office, through the Contact Centres, or with your travel companies. On the day of departure, passengers can also make a reservation for an unaccompanied minor. However, unless absolutely required, it is advised against making a last-minute minor reservation. It can depend on availability.
