Are Child Safety Seats Required on Airplanes?

SafeWise experts have years of firsthand experience testing the products we recommend. Learn how we test and review

Child safety seats are not required by the Federal Aviation Administration (FAA).1 However, both the FAA and the American Academy of Pediatrics (AAP) strongly encourage the use of a car seat or other child restraint system when flying with babies or young children.2

FAA-approved child seats are safer than laps

Unfortunately, your lap isn't the safest place for a child during a flight. Your arms aren't strong enough to securely hold a baby during turbulence or other unexpected events.3 Plus, you need your hands free to put on your oxygen mask if it's deployed.

A child seat is much safer. To help parents with babies and small children travel safely, the FAA provides a guide to airline-approved car seats. Here's a quick summary:

  • Front-facing car seats with a "certified for aircraft" label are the best option. 
  • Seats less than 16 inches wide fit most airplane seats.
  • Car seats must be installed in forward-facing airplane seats, preferably in a window seat.

In addition, the FAA has approved a child safety harness that is specifically designed for air travel. Called the Child Aviation Restraint System or CARES, these harnesses can be affixed directly to the airplane seat but are not approved for use in motor vehicles.

Why the FAA doesn't require child safety seats

The FAA chose not to mandate the use of an airplane car seat because it would force parents to purchase an additional ticket for their child, which could make air travel cost prohibitive for some families.3 The additional ticket would be required to reserve a seat in which an airline-approved car seat could be installed.

Currently, airlines allow children under the age of 2 to fly without a ticket, permitting them to sit on a parent or guardian’s lap. Because flying is statistically safer than car travel, the FAA has been reluctant to add barriers to air travel for families.4

Absolutely. Small children are too heavy to hold on your lap for the duration of a flight. Most airlines allow children under 2 to fly for free, but they'll need a seat of their own for a harness or safety seat. 

Children aged 2 or older need to have their own seat on a plane. 

They can, but it's not recommended. Infants and little ones are still heavy and in the event of turbulence or an emergency, you might not be able to hold onto them securely enough. 

Yes, if it's approved for air travel. Before it's time for your trip, check your child's carseat label. If it's certified for use in aircraft, you should be able to use it on the plane.
