Yes, many car seats can be used on airplanes, but they must be explicitly certified by the Federal Aviation (FAA). The easiest way to check is to look for a label on the car seat that states, "This restraint is certified for use in motor vehicles and aircraft" in red lettering. This is your guarantee of FAA approval. Seats that are only certified for motor vehicle use (with a sticker that says FMVSS 213) are not permitted for air travel.
Using an FAA-approved car seat is widely considered the safest way for a young child to fly. It provides a familiar, secure restraint system that is designed to protect them in the event of turbulence, which is far more common than a severe incident. Airlines typically require that the car seat be installed in a window seat so it doesn’t block other passengers' escape routes in an emergency.
When selecting a seat, consider the physical dimensions. Car seats must fit within the aircraft seat, which is typically 16-18 inches wide. Most infant car seats (rear-facing-only carriers) and convertible car seats fit this requirement, but wider models, like some all-in-ones or booster seats, may not. It's also important to note that booster seats, which use the vehicle's seat belt rather than a harness, are not approved for use during takeoff, landing, or taxiing because they require a lap and shoulder belt, which planes do not have.
| Factor | Requirement | Notes |
|---|---|---|
| Certification Label | Must have specific red FAA label for aircraft use. | Labels stating only FMVSS 213 are not sufficient. |
| Seat Type - Approved | Infant Car Seats, Convertible Car Seats (forward or rear-facing). | Must be installed with the aircraft's lap belt. |
| Seat Type - Not Approved | Booster Seats (backless or high-back). | Not allowed during taxi, takeoff, or landing. |
| Aircraft Seat Placement | Must be installed in a window seat. | Cannot be placed in an exit row or an aisle seat. |
| Child's Ticket | You must purchase a separate airline ticket for the child. | The car seat must be secured in its own purchased seat. |
Always check with your specific airline for any additional policies and inform them you will be using a car seat when you book your flight.

As a mom who’s flown cross-country with a toddler, my top tip is to look for the words "for use in aircraft" on the seat's label. If it’s there, you’re good to go. We used our standard convertible car seat—the one we use every day. It was a lifesaver because our kid was comfortable in his own familiar seat, and we knew he was safe. Just make sure it fits in the airplane seat; most do. Leave the bulky booster seat at home, though; they won’t let you use it.

The core rule is simple: the car seat must be labeled as certified for aircraft use. This FAA certification is separate from its motor vehicle certification. Approved types include infant seats and harness-based convertible seats. Booster seats, which on a vehicle's lap-shoulder belt system, are not permitted on planes. The seat must be secured in a window seat using the aircraft's lap belt. Always confirm with your airline ahead of your flight.

I always tell my friends to stick with their infant carrier or their convertible seat for the plane. Brands like Graco, Britax, and Chicco typically have models that are FAA-approved—just double-check the label. The key is that the seat has its own five-point harness. That’s what the FAA wants to see. It’s safer for the kid and gives you peace of mind. The airline staff will help you get the lap belt tightened correctly around it.

From my experience, using an FAA-approved car seat is less about the rules and more about practicality. It gives your child a dedicated space that’s familiar, which can help them sleep on a long flight. You’ll need to book them their own ticket and install it at the window. The flight attendants are used to it and can assist. The biggest mistake I see is parents bringing a booster seat, which isn't allowed. Stick with a harnessed seat, and your travel day will be much smoother.
