-- Most airlines require children traveling alone to be at least five years of age and charge a fee (in addition to the fare) for escorting the child on and off flights.
-- For safety purposes, most airlines require information about who is bringing your child to the airport and who is meeting him or her at the final destination.
-- To ensure that your child is released to the proper person, the adult meeting your child at the final destination must show identification.
-- If your unaccompanied child is between 5 and 7 years old, most airlines allow them to fly only on nonstop flights.
-- Make sure to ask the airline for an unaccompanied minor form, as well a pin for your child to wear so that the airline staff can easily identify your child as a minor traveling.
-- Give your child a calling card or teach him or her to make a collect call so they can reach you anytime, anywhere.
