For most families flying with a young child, the WAYB Pico is the best travel car seat: it folds flat to roughly the size of a laptop bag, carries FAA approval for airplane use, and covers children from about 26 to 50 pounds. It isn't the only good option though: a budget-friendly convertible seat, a slim seat built for three-across seating, and a pocket-sized booster for older kids each solve a different travel problem.
This guide compares published specifications, weight and height limits, and documented user experience. None of these seats were tested hands-on for this article.
Quick summary: the WAYB Pico is the best all-around travel seat for toddlers and preschoolers. Families on a budget should look at the Cosco Scenera NEXT, and school-age kids who just need a booster are better served by the mifold.

Why FAA approval matters
An FAA-approved car seat carries a label confirming it's certified for use on an aircraft, which means it can be installed on a plane seat with a standard lap belt for takeoff and landing, not just in a car. Not every car seat carries this certification, so it's worth confirming before assuming a seat can travel in the cabin rather than the cargo hold. All five seats in this guide are documented as approved for airplane use by their manufacturers.
Foldable travel seats vs everyday convertible seats
There are two real approaches to a travel car seat. The first is a purpose-built foldable seat like the WAYB Pico, designed from the ground up to compress down for a backpack or overhead bin, at a premium price. The second is simply traveling with a lightweight everyday convertible seat, like the Cosco Scenera NEXT or Diono Radian 3RXT, which don't fold as small but cost less and double as the seat already installed in the family car. Which makes sense depends on how often the family flies: frequent flyers get more value from a dedicated folding seat, while occasional travelers may prefer not to buy a second seat at all.
WAYB Pico Travel Car Seat
Pros
- Folds flat to about the size of a laptop bag
- FAA-approved for airplane use
- Forward-facing for children roughly 26.5 to 50 pounds and 33.5 to 45 inches
Cons
- Premium price compared to a standard convertible seat
- Forward-facing only, not suitable for infants who still need rear-facing
WAYB Pico Travel Car Seat
Built specifically to travel, not adapted from an everyday seat. The fold is the smallest in this comparison, which matters most for families who fly several times a year.
Cosco Scenera NEXT Convertible Car Seat
Pros
- One of the lightest, least expensive convertible seats on the market
- FAA-approved and rear- or forward-facing depending on the child's age
- Compact footprint fits narrow airplane seats
Cons
- Fewer comfort features than premium convertible seats
- Doesn't fold flat like a dedicated travel seat
Cosco Scenera NEXT Convertible Car Seat
The seat most frequently recommended as a second car seat purely for travel, thanks to its low price and narrow shape, even though it doesn't collapse down like a purpose-built travel seat.
Diono Radian 3RXT
Pros
- Slim enough to fit three car seats across one row
- Rear- and forward-facing, built to last from infancy through the booster years
- Steel-reinforced frame documented for crash protection
Cons
- Heavier than a dedicated travel seat like the WAYB Pico
- Bulkier to carry through an airport than a folding seat
Diono Radian 3RXT
Less about the airport walk and more about a seat that keeps working for years, in the car and on the road, without needing to be replaced as the child grows.
mifold Grab-and-Go Booster Seat
Pros
- Folds down to about the size of a large book
- Fits in a backpack or large purse
- Designed for kids who have outgrown a full car seat but still need a booster
Cons
- Only suitable for children who meet backless booster height and weight requirements
- Sits lower than a high-back booster, which some kids find less comfortable
mifold Grab-and-Go Booster Seat
The obvious pick once a child has outgrown a full car seat but still legally needs a booster: it fits in a bag rather than needing its own suitcase.
Britax Car Seat Travel Bag
Pros
- Padded backpack straps for carrying a car seat hands-free through an airport
- Built-in wheels for rolling instead of carrying
- Water-resistant fabric protects the seat during gate-checking
Cons
- An extra item to pack and store when not traveling
- Doesn't reduce the seat's actual size or weight
Britax Car Seat Travel Bag
Not a seat itself, but the accessory that makes gate-checking any of the seats above less stressful, protecting the seat from the wear that gate-checked luggage takes on.
Which to buy
Buy the WAYB Pico if the family flies more than once or twice a year and the smaller fold and lighter carry are worth the higher price. Choose the Cosco Scenera NEXT if budget is the main constraint or if a second seat is only needed occasionally. Pick the Diono Radian 3RXT if three seats need to fit across one row, or if the seat needs to last from infancy through the school years rather than being travel-specific. Once a child only needs a booster, the mifold replaces a bulky high-back booster with something that fits in a backpack. Whichever seat travels, a Britax travel bag keeps it protected if it has to be gate-checked.

Frequently asked questions
Do all car seats work on airplanes?
No. Only seats labeled as FAA-approved (or approved for aircraft use in the seat's manual) are certified to be installed on a plane using the seat's lap belt. Airlines generally do not allow bassinets or seats without this certification to be used during takeoff and landing.
Is a foldable travel seat like the WAYB Pico necessary, or can families just bring their regular seat?
It depends on how often the family flies. A dedicated folding seat is lighter and easier to carry through security and onto a plane, which matters most for frequent flyers. Occasional travelers may find it simpler to bring the convertible seat already installed in the car.
At what age can a child switch from a car seat to a booster like the mifold?
This depends on the child's height and weight rather than age alone, and on the specific booster's stated minimum requirements. Most backless boosters require a child to have outgrown the weight or height limit of a forward-facing harnessed seat first.
Does gate-checking a car seat damage it?
It can, since gate-checked items go through the cargo hold and are handled like luggage. A padded travel bag with wheels significantly reduces the risk of cosmetic or structural damage during this process.
