What makes a car seat approved for airplane use
An aircraft-approved car seat is one that meets Federal Aviation Administration (FAA) standards and carries a label stating it is approved for use during flight. The FAA does not certify car seats itself — instead, manufacturers test their seats against FAA requirements and label them if they pass. You are looking for a sticker or tag on the seat that says "This restraint is certified for use in motor vehicles and aircraft" or similar language.
The seat must be installed in a window seat (never the middle or aisle seat) and must be secured with the airplane's seat belt, not the LATCH system you use in your car. Not all car seats that are safe in vehicles meet the width and installation requirements for aircraft cabins, which is why the manufacturer's label matters — it tells you the seat has been tested for both environments.
You will need to purchase a ticket for your child to occupy the seat on the plane. The FAA recommends but does not require that children under 2 years old be restrained during flight, though many airlines now require it. Infants can also travel in a bassinet provided by the airline if your seat is approved for that use.
Key Takeaways
- An aircraft-approved car seat must have a manufacturer's label stating FAA approval — this label is your proof the seat meets airplane safety standards.
- The seat installs using the airplane's seat belt only, not the LATCH connectors you use in your car, and must go in a window seat.
- Your child needs a paid ticket to use the car seat on the plane; you cannot use it in a lap-held position.
- Width and depth matter: the seat must fit between the airplane armrests and not block the aisle or emergency exits.
- Many popular car seats are approved for aircraft use, but some are not, so check the manufacturer's label before booking your flight.
How to check if your current car seat is approved
Look for a label on the back, side, or bottom of your car seat. The label will state approval for aircraft use explicitly. If you cannot find a label or are unsure, check the manufacturer's website or the instruction manual that came with the seat — both usually list which models are FAA-approved. You can also contact the manufacturer's customer service with your seat's model number.
Do not assume a seat is approved because it is new or expensive. Some well-known brands make both approved and non-approved models. The only reliable source is the manufacturer's documentation or label on the seat itself. If you are buying a used seat, inspect it carefully for the label and ask the seller for the original manual if possible.
Which car seats are commonly approved for aircraft
Convertible car seats and forward-facing seats are more likely to be approved than rear-facing infant seats, though some infant carriers do have approval. Popular brands with approved models include Graco, Chicco, Britax, and Evenflo, but within each brand, only certain models carry the FAA label. Booster seats are generally not approved for aircraft use because they are designed to work with a vehicle's seat belt in a specific way that does not transfer to airplane seating.
Width is the limiting factor for many seats. Airplane seats are narrower than car seats, and the car seat must fit between the armrests without blocking the aisle or emergency exit row. Even if a seat is approved, it may not fit in every airplane seat due to the aircraft's specific dimensions. Some airlines provide seat width information on their websites, and you can measure your car seat to compare before you travel.
How to install an approved car seat on an airplane
First, book a window seat for your child and purchase a ticket in that seat. When you board, locate the window seat and check that the armrests can be raised or moved — some newer aircraft have fixed armrests that will prevent installation. If the armrests cannot move, ask the flight attendant to move you to a different window seat.
Thread the airplane's seat belt through the car seat's belt path, following the path marked in your car seat's manual for airplane use. This path is usually different from the vehicle installation path. Fasten the airplane seat belt and tighten it so the car seat does not move side to side or forward and backward. The car seat should be snug but not so tight that you cannot remove it if needed.
Do not use the car seat's LATCH connectors on the airplane — they are not designed for aircraft seats and will not find the seat properly. Once the seat is installed, have a flight attendant inspect it before takeoff. Many airlines require this, and the attendant can catch installation errors that you might miss.
Traveling with a car seat you do not own
If you are renting a car at your destination, you may want to rent a car seat from the rental company rather than travel with your own. Car rental agencies offer infant and child seats, though availability varies and you should reserve one when you book the car. These rental seats are typically not approved for aircraft use, so you will still need to bring your own approved seat if you plan to use one on the plane.
Some families purchase a lightweight, compact car seat specifically for travel that is approved for both vehicles and aircraft. These seats are designed to be easier to carry through airports and fit in overhead bins or under seats when not in use. If you travel frequently with a child, this may be worth the investment, but for occasional trips, using your existing approved seat is usually the simpler choice.
What airlines need to know before you board
Contact your airline before your flight to confirm their specific rules about car seats. Most major U.S. airlines allow approved car seats, but policies on where they can be installed, whether they are required, and how they are handled during boarding vary. Some airlines have restrictions on certain seat types or require advance notice.
Ask the airline whether they provide seat belt extenders if your car seat's belt path requires extra length, and whether they can confirm that your specific aircraft has movable armrests in the window seats. Having this information before you arrive at the airport prevents delays and confusion at the gate. If you are traveling internationally, check the destination country's rules as well — some countries have different requirements for child restraints on aircraft.
Alternatives if your car seat is not approved
If your car seat does not have an FAA approval label, you have a few options. You can purchase an approved car seat before your trip — many retailers offer them, and you may be able to find one secondhand if cost is a concern. You can also check whether your airline offers loaner car seats, though this is rare and usually requires advance booking.
Another option is to have your child sit in a regular airplane seat without a car seat. The FAA recommends but does not require restraint for children over 2 years old, and many families choose this route. For infants under 2, you can hold them in your lap during flight, though the FAA recommends against this and suggests using an approved seat or bassinet instead. If you choose not to use a car seat, your child will still need a ticket to have their own seat.
Frequently Asked Questions
Can I use a car seat in the middle or aisle seat on a plane?
No. FAA rules require that car seats be installed only in window seats. Middle and aisle seats do not provide the structural support needed for safe installation, and a car seat in those positions would block the aisle or emergency exits. Always book a window seat if you plan to use a car seat.
Do I have to pay for a ticket if my child sits in a car seat?
Yes. Your child needs a paid ticket to occupy a seat on the plane, whether they are in a car seat or sitting alone. Infants under 2 can travel on a parent's lap without a ticket, but if you want to use a car seat for an infant, you must purchase a ticket for that seat.
What happens if the car seat does not fit in the airplane seat?
If the seat is too wide or does not fit between the armrests, you will not be able to use it on that aircraft. You can ask the flight attendant to move you to a different window seat, or you can choose not to use the car seat for that flight. Measure your car seat's width before you travel and compare it to the airline's seat dimensions if possible.
Can I gate-check my car seat if I am not using it on the plane?
Yes. Most airlines allow you to gate-check a car seat at no charge, meaning you can bring it to the gate and check it with your stroller or other items rather than carrying it onto the plane. This is useful if you are renting a car at your destination and want to use your own seat there but not on the flight.
Are booster seats approved for airplane use?
No. Booster seats are not approved for aircraft use because they are designed to work with a vehicle's lap and shoulder belt in a way that does not transfer to airplane seating. If your child uses a booster seat in the car, you will need to use a different approved car seat or forward-facing seat on the plane.
