Best Answer: if they are lap children (sitting on your lap for entire flight) they have to be 2yo and under and its free... if you they occupy a seat regardless of age you pretty much pay for full adult price, few airlines do give #% discount, but not that much, maybe 10% or 15%... You pay for a childs seat at age 2 or older. Federal Aviation Regulations state that any person older than 2 y/o must OCCUPY a Seat in the cabin. Most airlines offer a discounts for children and infants.
When it comes to traveling with kids in the U.S., children in their own seats will pay the same fare as adults no matter how old (or young) they are. Lap children, on the other hand, pay nothing but they must be under 2 years of age. If they turn 2 in the middle of a trip, you will have to pay for a return ticket.
