What is in this guide
If you have ever lugged a car seat down a jet bridge with a toddler on your hip, you have probably wondered whether there is a smaller way to keep your child safe in their airplane seat. There is, and it is called the CARES harness. It is the only FAA-approved airplane harness for toddlers, it weighs about a pound, and it packs down into a pouch smaller than a water bottle. This guide explains exactly what it is, how it works, and when it makes sense to bring it instead of hauling a full car seat on board.
One honest note first: we have not personally flown with this specific harness, so this is a research post built on what owners, testers, and the manufacturer report, plus what we know from flying with our own gear. When we point to a car seat as the alternative, that is gear we have used first-hand.
What is the CARES harness?
CARES stands for Child Aviation Restraint System, made by AmSafe. It is the first and only FAA-approved harness-type child aviation restraint, certified for use during taxi, takeoff, turbulence, and landing. In plain terms: it is the only belt-and-strap device the FAA lets you use in place of a car seat to keep a small child secured in an airplane seat.
It is built for children who weigh 22 to 44 pounds, are about one year and older, are up to 40 inches tall, and can sit upright on their own in a forward-facing seat. Below 22 pounds, a child still needs an FAA-approved car seat on board.
Here is the part that trips people up, so I will say it plainly: the CARES harness is not a car seat. It is approved for airline use only. You cannot use it in a car, a taxi, or a rental. It works only on a forward-facing airplane seat, and only in the air.
How the CARES harness works
Setup takes a few minutes. The harness loops around the back of the airplane seat and connects to an adjustable strap that tightens across the seat back. The airplane’s own lap belt then threads through the harness, and a shoulder-harness system comes over your child’s shoulders and clips into that lap belt. The result is an upper-body restraint, using the plane’s existing seat belt as the anchor.
Because it relies on the seat back and the lap belt, it works on standard forward-facing airline seats. It is not designed for side-facing or lie-flat business seats, and airline crews will confirm it is installed correctly. At about one pound, it lives in your personal item instead of eating a checked-bag slot.

When to use the CARES harness instead of a car seat
The harness shines in one very specific situation: your child is 22 to 44 pounds, and you have ground transportation covered at your destination without needing your own seat. Think a trip where you are met by family who already have a car seat, or a Disney trip where you rely on airport transfers and park transport rather than driving a rental. In that case, dragging a full car seat through the airport just to strap it in for a two-hour flight is a lot of effort for a device you will not touch again all week.
Bring a car seat instead when you will be driving at your destination, when your child is under 22 pounds, or when you want one familiar device that covers both the plane and the car. If that is you, look at a light, inexpensive, FAA-approved seat like the one in our Cosco Scenera Next review, and see the full field in our best travel car seat guide.
Pros and cons of the CARES harness
Pros owners report:
- Feather-light at about one pound and packs into a 6-inch sack.
- The only FAA-approved airplane harness for toddlers, so it is legal for all phases of flight.
- No wrestling a bulky seat down the aisle or gate-checking anything.
- Keeps a squirmy toddler upright and contained better than a lap belt alone.
Cons to weigh:
- Plane only. It does nothing for you in a car, so you may still need a car seat at your destination.
- Forward-facing standard airline seats only.
- Only for children 22 to 44 pounds who can sit upright.
- Costs about as much as a budget car seat, despite doing less.
FAQ
Is the CARES harness really FAA-approved, and can I use it during takeoff and landing?
Yes. CARES is FAA-certified as a child aviation restraint for all phases of flight, including taxi, takeoff, turbulence, and landing. It carries the required approval label. It is approved for aircraft use only, not for cars.
Can I use the CARES harness in a car or taxi?
No. This is the single most important thing to understand. It is not a car seat and has no vehicle approval. If you will be driving at your destination, you still need a proper car seat.
What if my child is under 22 pounds?
Then the harness is not for you yet. Children under 22 pounds should fly in an FAA-approved car seat installed in their own airline seat.
Do I still need to buy a seat for my toddler to use it?
Yes. The harness attaches to an airplane seat, so your child must have their own purchased seat. It does not work if your child is a lap infant.
The verdict
The CARES harness is a brilliant answer to one specific problem: keeping a 22-to-44-pound toddler safely upright in an airplane seat without dragging a car seat through the terminal. If your destination transport is already handled, it is a pound of packed-down peace of mind. If you will be driving once you land, or your child is still under 22 pounds, a light FAA-approved car seat like the Cosco Scenera Next does double duty for not much more money. Just remember it is a plane-only device, never a car seat.
