In the United States, Canada and Mexico, children under age two are allowed to fly for free on the lap of their parents. But it is strongly recommended that parents consider buying a separate seat for their child for safety reasons. But in the U.S., you can't just bring any car seat. it must be a seat that has been approved for travel by the Federal Aviation Administration (FAA).

It must also be able to be fastened to the aircraft seat by a two-point harness. Parents must advise the airline when purchasing a ticket about carrying a car seat. 
  2. Air Canada: Car seats must have a label stating "This child restraint system conforms to all applicable Canadian Motor Vehicle Safety Standards", or have a National Safety Mark, which indicates the number of the standard(s) to which the restraint device conforms.

American Airlines: The Fort Worth, Texas-based carrier requires car seats to have a solid back and seat, restraint straps installed to securely hold the child and a label indicating approval for use on an aircraft.

Tips for Using a Car Seat During a Flight

  • To be able to use your car seat you will be looking for a label that states: "This restraint is certified for use in motor vehicles and aircraft." 
  • Check the width of the car seat. In the U.S., the FAA mentions 16 inches as the maximum width so that it will fit most airline seats.
  • Some airlines offer discounted airfares for infants occupying a seat, but not all. For airlines that do offer discounted airfares for infants, discounts tend to range from 10-50 percent less than an adult's airfare.
  • If you do not purchase a seat for your child under two, the airline is not required to give you an empty seat. Mid-week and late morning or early afternoon flights often give you a better chance at extra empty seats on an aircraft. And you can always ask at the gate.
