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.
For the rules, each traveler over the age of 12 may accompany 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 internationally, 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.
