Domestic Travel: One child, less than 24 months of age, may travel free of charge within the U.S. when accompanied by an adult. Federal regulations permit adult passengers to hold an infant in their laps (under 24 months of age). If you do not want your child to sit on your lap for the duration of the flight or prefer the use of a car seat, you will need to book a separate airline ticket. In addition, the airlines permit only one lap child per adult traveler. You'll need to book an airline seat for each infant exceeding the number of adult travelers.

International Travel: When traveling internationally, all children and infants must have an airline ticket even if they will be sitting on an adult's lap. Airlines prefer children to remain properly secured in their seats during the flight. All passengers, including children and infants, are required to secure passports in their own names. (Because of our specially negotiated low airfares, Hotwire does not sell discount infant or child airfares.)

Hotwire does not offer any discount child fares. In many cases, the airfares we show you are lower than a standard discount airline ticket.
