Best Lightweight Car Seats for Traveling
Updated November 2022
It’s the travel season once again, and for many families with small children that includes flying somewhere. Since so many carseats are heavy and bulky, it makes sense in some cases to invest in a lightweight carseat just for traveling. Plus, this spares you the hassle of re-installing your main carseat when you get back to your own car, weary from traveling.
Ideally, a spare travel carseat should be lightweight (under 15 lbs), easy to install with the lap belt on an airplane seat and narrow enough to fit in a typical coach/economy seat.
With those criteria in mind, here are our favorite travel carseats:
Infant carseats – no need to buy anything new as long as your current infant seat can be installed without the base. I guess it’s possible to drag the base with you on your trip but that’s just making life harder than it needs to be. As long as your infant seat allows installation without the base (most do but there are some exceptions so make sure you know for sure), it’s easy to install the carrier rear-facing with the lap-only belt on the plane.
If you’re leaving the base at home – make sure you practice baseless installation a few times so when you arrive at your destination you know how to install the carseat properly in the car, using a typical lap/shoulder belt. We have a VIDEO HERE that demonstrates my technique for quick and easy installations of an infant carseat without the base.
Please Note: Using a wrap, sling, front pack or any type of babywearing device is NOT a safe alternative for your baby or toddler because they aren’t engineered to restrain your child in any event that can be measured in g forces. Plus, you technically aren’t allowed to wear your child during take-offs or landings when the risks are highest. If you would like more info on why slings and infant carriers are not a safe alternative to using a carseat on a plane, please see this information from the NTSB website.
Also, please stay clear of gimmicky products like baby vests that attach to your seatbelt, baby hammocks, and whatever this belly band thing is… ??? These products are not FAA-approved and you’re just wasting your money. Save your hard-earned dollars for some inflight prosecco once your baby falls asleep… in their safe and familiar carseat.
If you plan to install the convertible seat rear-facing on the plane then you’ll be best served by a seat that is fairly compact which will increase your chances of the seat actually fitting rear-facing in the space you have to work with.
Rear-facing 5-40 lbs., or up to 40″ tall. Forward-facing 22-40 lbs., or up to 40″ tall
Rear-facing 5-40 lbs., or up to 37″ tall. Forward-facing 22-40 lbs., or up to 40″ tall
Rear-facing 5-40 lbs. Forward-facing 22-65 lbs., or up to 49″ tall.
No matter which seat you decide to take on the plane for your child – you will want to know where the FAA approval is located, in case one of the flight attendants asks to see proof that your carseat is certified for use in an aircraft. Look for RED lettering on one of the sticker labels. The FAA language is required to be written in red but the sticker label placement will vary from seat to seat. The language can vary slightly but in general, this is what you’re looking for:
For forward-facing kids, you’ll be best served by a seat that’s lightweight, fairly narrow, with tall top harness slots and a weight limit of 50 lbs. or more. Keep in mind that combination seats (aka harness/booster) can only be used on the plane in harnessed mode. Booster seats (or combination seats used without the 5-pt harness in booster mode) are not FAA certified and cannot be used on an airplane because all booster seats require a lap/shoulder belt, which airplanes don’t have.
Forward-facing only for kids at least 2 years old. With 5-point harness from 22-50 lbs., up to 50″ tall
Rear-facing 5-40 lbs., or up to 40″ tall. Forward-facing for children at least 2 years old, 22-65 lbs., up to 50″ tall
Rear-facing 5-40 lbs., Forward-facing for children at least 1-year-old, 22-65 lbs., or up to 49″ tall. *Forward-facing beltpath is behind the back of the shell. This unique design means your FF child won’t have the metal latchplate of the airplane seatbelt in their back during the flight.
Rear-facing 5-40 lbs., or up to 40″ tall. Forward-facing for children at least 1-year-old, 22-65 lbs., up to 43″ tall. Ditch the optional cup holders for the flight because they just take up space.
Niche folding travel seat. Expensive. Forward-facing only for kids at least 2 years old. 22-50 lbs., 30-45″ tall. We have a review of the WAYB Pico.
A unique product for kids over 1-year-old who weigh between 22-44 lbs., and are under 40″ tall. *CARES harness is certified for use ONLY on the plane. It cannot be used in vehicles. It’s very useful for situations where you don’t need a carseat to use on the ground when you arrive at your destination. We have a review of the CARES Harness.
If you want to travel with your usual carseat, there are many products that can help you transport it through the airport. Some are just generic luggage carts. Some products, like the inexpensive Traveling Toddler Strap, are made specifically for a carseat. There are also carseat travel bags with wheels but obviously, you can’t put your kid inside it too. Remember, the whole point is to use your carseat on the plane so you don’t need an expensive travel bag to protect your carseat. You just need to find a convenient way to get it from your car to the plane and back.
Britax makes a folding travel cart accessory specifically for Britax carseats but there is no reason why it shouldn’t work for other brands of car seats too.
Remember, only carseats with an internal harness can be used on a plane. You cannot use a booster seat on an airplane because booster seats require a lap/shoulder belt and airplanes only have lap belts. If your child rides in a booster seat and you are bringing it with you, you can gate check it or bring it on the plane and put it in the overhead bin (if it fits).
