Air Travel Guidelines for Children
We're here to help you prepare to fly with your children. Here's how it works.
Booking a child's ticket
You'll need to buy a separate ticket if:
· You book an international flight.
· Your child is 2 years old or older at takeoff.
· Your child is a baby sitting in his or her own seat.
In some cases, children can fly for free. If everything below is true, you won't need to buy your child a separate ticket:
· You book a domestic（国内） flight.
· Your child is a baby（less than 2 years old）, at takeoff.
· Your baby sits on the legs of a traveler over the age of 12.
· No more than 1 baby is seated on the legs of a traveler.
Now for the rules, each traveler over the age of 12 may accompany（陪伴） up to 2 babies, each seated in their own seat.
Documents a child will need
The airlines determine what documents you'll need to travel. In short, if you're flying domestically, each child might need a photo ID. If you're flying intemationally, each child will need a passport. Additionally, children under 18 traveling to Mexico need to provide proved documentation and letters of permission. For more information, please visit the US Embassy（大使馆） website.
Unaccompanied children on flights
· Some airlines may charge a fee for unaccompanied child service.
· Children under 5 and over 17 might be unfit for unaccompanied child service.
· Both the adult dropping the child off at the airport and the adult picking the child up are required to show identification.
Contact your airline to ask about more information.
