Flying with your car seat

Last updated July 2019.

Flying with your child?  Here’s how to deal with car seats, in order of preference:

1) Buy a ticket for your baby. A ticketed child, regardless of age, is allowed to use a car seat on board the air craft (nearly all seats for sale in Canada and bearing the National Safety Mark are certified for use on an air craft).  Safer for your child, safer for other passengers (your child won’t be a projectile), and safer for your car seat.  Use a rolling, folding luggage cart to roll through the airport.  Have more than one seat? Bungee them together! Click here to read the Child Passenger Safety Association of Canada‘s position statement on the need for all passengers to be safely seated on flights.

2) Arrange to have a seat at your destination, either borrowing from a trusted source or buying a new one (ordering online and shipping to your destination is a possibility).

***You still don’t want your child to be a projectile though. Consider using a CARES harness on board the aircraft, which restrains your child using the lap belt on the plane.  They’re for use with children between 22 lbs and 44 lbs, and up to 40″ tall, but please note there’s no crotch buckle so smaller kids can squirm out. After 40 lbs or so the plane’s lap belt is usually sufficient.  Click to see where to buy a CARES harness.  They cost around $100, and are lightweight and small, so can easily be stowed in a carry on bag for boarding.  Please, however, disregard CARES’ advice to ‘check your car seat and use a CARES harness instead.’

3) Box your car seat, in the original box if possible, and well-padded with pillows or clothes. Check it as special luggage.  It may be free if in the original box.


Much less desirable options from our perspective:

  • Gate check your car seat.  Walk it down the jet way, leave it at the door to the plane, and hope it’s there at your destination. No guarantees it won’t get battered in the hold, or it won’t accidentally get loaded onto the conveyors with the rest of the luggage. Inspect it carefully at your destination, removing the cover and looking for damage in any foam, plastic, or webbing.
  • Rent a car seat from a car rental place. You have NO IDEA how it’s been treated – dropped? – crashed? – harness washed or disinfected? – peed/pooped/vomited in? Is the manual there? Is it missing any parts?  Is it appropriate for your child or is your infant being given a booster seat?
  • Check your car seat as luggage. It’s free. Lot’s of people do it. It might get destroyed or lost though. Inspect it carefully at your destination, removing the cover and looking for damage in any foam, plastic, or webbing.


Watch the video below to see how car seats are treated when checked. Notice he’s just tossing the car seats on the runway. Car seats aren’t meant to be dropped, let alone tossed onto pavement.
