International travel

Some airlines automatically apply the unaccompanied-minor procedures to kids through age 17 on international flights,
and charge the standard unaccompanied-minor fee if applicable. Children must usually have the same passport, visa
or other international entry documentation required of adults.
In addition, certain countries require children leaving that country without both parents or a legal guardian to have a letter of consent,
in some cases notarized. Check with the embassy or consulate in the U.S. of the destination country for its requirements.
Airlines and travel agents are not responsible for ensuring that your child has the required international travel documents,
but they sometimes can provide useful information.
