How to Use a Car Seat on a Plane
You can bring a car seat on board if it is FAA-approved and you have purchased a separate seat for your child. Check the label on the side of your seat for the 'Certified for use in aircraft' stamp before you head to the airport.

Step by step
Verify FAA approval
Look for the red text on your car seat's label stating 'This restraint is certified for use in motor vehicles and aircraft.' If your seat doesn't have this, it cannot be used on board.
Book a separate seat
A car seat cannot be used in a lap-infant scenario. You must purchase a ticket for the child and ensure the car seat fits within the airline's seat width dimensions.
Select a window seat
FAA regulations require child safety seats to be placed in a window seat so they do not block the escape path to the aisle. Do not book an exit row; car seats are strictly prohibited there.
Install the seat correctly
Raise the armrests. Place the car seat forward-facing, route the airplane seatbelt through the belt path, pull it tight until the seat doesn't budge more than an inch, and buckle it.
Questions people ask
Can I use a booster seat on the plane?
No. Booster seats that require shoulder belts are not permitted during takeoff and landing because airplane seats only have lap belts.
What if my car seat is too wide for the airplane seat?
If it doesn't fit, you must gate-check it. Always check your car seat's width against your airline's specific seat dimensions—usually 16 to 17 inches—before you fly.
Do I need to inform the airline?
It is good practice to call ahead and add a note to your reservation that you are bringing a car seat, though it is not strictly required by most domestic carriers.
Budget
Bringing a car seat is free if it's your child's carry-on or checked item. If you choose to use it on the plane, the cost is the price of the extra airline seat required for the child.
