FAA Approved Car Seats for Flying: What Parents Need to Know

If you're planning to fly with a young child, you may have heard the term "FAA approved car seat" and wondered what it actually means — and whether your existing car seat qualifies. Here's how the approval system works, what to look for, and why the answer isn't always straightforward.

What "FAA Approved" Actually Means for Car Seats

The FAA doesn't issue a separate aviation certification for car seats. Instead, the agency allows certain existing car seats — those already certified for use in motor vehicles — to be used on aircraft, provided they meet specific labeling and design requirements.

The key label to look for is:

"This restraint is certified for use in motor vehicles and aircraft."

If a car seat carries this exact language, the FAA permits it on commercial flights. Seats that say "certified for use in motor vehicles only" are not permitted on planes, even if they're otherwise high-quality seats.

This distinction matters because car seat manufacturers choose whether to certify their products for aircraft use. Not every seat makes the cut, and the labeling varies slightly across brands and model years.

Which Types of Car Seats Are Generally Permitted

Most rear-facing infant seats, convertible car seats, and forward-facing harnessed seats that carry the correct FAA label are allowed on aircraft. There are some important carve-outs:

• Booster seats (backless or high-back boosters that rely on the vehicle's seat belt) are not permitted on aircraft. The aircraft seat belt geometry is different from a car's, and boosters are not designed for that environment.
• CARES harness (Child Aviation Restraint System): This is a separate FAA-approved harness designed specifically for aircraft use, not for cars. It works for children roughly 22–44 lbs and is a popular travel option because it's lightweight and packable.
• Belt-positioning devices and other add-ons that aren't standalone car seats are generally not FAA-approved for aircraft.

How to Check Your Specific Car Seat ✈️

The label check is the most reliable method. Look on the side panel or back of the seat's shell — not the instruction manual — for the certification language. The exact phrasing matters.

If you're unsure:

• Check the manufacturer's website for your seat's model and production year
• Contact the manufacturer directly — most have customer support lines
• Review the seat's instruction manual, which often lists aircraft use eligibility

Keep in mind that older car seats may predate current FAA language standards. Even if a seat is structurally similar to an approved model, it needs to carry the correct labeling to be used on a plane.

Why Airlines May Have Additional Rules

The FAA sets minimum requirements, but individual airlines may impose additional restrictions. Some airlines require that the seat fit within the aircraft seat — typically no wider than 16 inches — to qualify for use. Wide-bodied convertible seats sometimes don't fit in economy class seating on narrower aircraft.

Airlines also generally require that:

• The car seat be placed in a window seat so it doesn't block aisle evacuation
• The child occupy a ticketed seat with the car seat installed (lap children using a parent's car seat isn't typically allowed)

It's worth verifying your airline's specific policy before you fly, since these rules aren't uniform across carriers.

Variables That Affect Whether Your Seat Will Work on a Plane

Why You Might Use a Car Seat on a Plane at All

The FAA and the American Academy of Pediatrics both recommend that children — especially those under 2 — use an appropriate restraint system on aircraft rather than sitting as a lap child. Turbulence is the most common cause of in-flight injuries, and a properly installed car seat provides real protection.

That said, using a car seat on a plane requires a purchased seat for the child, which adds cost. Families weigh that expense against the safety benefit differently depending on the length of the flight, the child's age, and their budget.

The Pieces That Are Specific to Your Situation

Whether your car seat is approved for flight comes down to that label — but whether it will work on your specific flight depends on your airline's rules, your aircraft type, your seat assignment, and how your child fits in the seat at their current size. 🧒

A seat that works perfectly on one carrier's wide-body international route may not fit in a regional jet's economy seat. A seat that was approved when purchased may be past its expiration date by the time you travel. Those specifics — your seat, your airline, your route — are the variables only you can verify before you fly.
