Best car seats for airplanes & travel in the US (2026): Cosco Scenera Next, WAYB Pico, Doona & CARES compared
Key facts
Short answer: the #1 all-around and budget US airplane car seat is the Cosco Scenera NEXT ($59, 6.8 lbs / 3.1 kg, 17 in wide, FAA certified for rear- and forward-facing 5–40 lbs). For toddlers 2+ (22–50 lbs), the WAYB Pico ($380, 8 lbs) folds to fit in overhead bins; for infants 0–12 months, the Doona ($550, 17.2 lbs) converts from an FAA car seat into a stroller in 2 seconds.
If you have ever tried carrying a 28-pound everyday convertible car seat through an airport terminal — only to discover it is wider than a 17-inch Boeing 737 economy seat — you already know why seasoned flying parents keep a dedicated lightweight travel car seat for flights, rental cars, and Uber/taxi rides.
To use a car seat inside a purchased airplane seat on Delta, United, American Airlines, Southwest, JetBlue, or Alaska Airlines, it must meet two strict requirements (explained in full in our FAA car seat rules on planes guide):
- It must display the red FAA aircraft certification lettering ("This restraint is certified for use in motor vehicles and aircraft") or an accepted foreign aircraft mark (CMVSS / UN ECE with TÜV sticker).
- It must fit into a window seat without blocking the aisle (the FAA recommends a base width under 16 to 17.5 inches, though raising the movable middle armrest helps).

1. Best overall & budget travel car seat (ages 0–3): Cosco Scenera NEXT ($59)
Ask any frequent-flying US parent or Child Passenger Safety Technician (CPST) for the single best airplane and travel convertible car seat, and the answer is almost universally the Cosco Scenera NEXT:
- Weight: 6.8 lbs (3.1 kg) — lighter than most loaded diaper bags! You can hang it by its top tether strap from the handlebar of a Bugaboo Butterfly 2, Joolz Aer+, or UPPAbaby Minu V2 and push it through the airport with one hand.
- Dimensions: 17 inches wide (
43.2 cm), meaning it drops cleanly between the armrests of Boeing 737 and Airbus A320 window seats on Delta, United, American, Southwest, and JetBlue. - Rear-facing & forward-facing: Covers 5 to 40 lbs (19 to 40 in) rear-facing and 22 to 40 lbs (29 to 43 in) forward-facing, satisfying mandatory rear-facing under age 2 laws in states like California, New York, and Hawaii.
- Airplane belt path tip: Because the Scenera NEXT's forward-facing belt path sits behind the thin seat pad, the airplane lap belt buckle rests behind the padding rather than pressing into your toddler's back.
- Price: $59 MSRP (Check price) — less than the cost of renting a mystery car seat from Hertz or Avis for four days!
2. Best folding travel car seat for toddlers (2+ years): WAYB Pico ($380)
Once your toddler is at least 2 years old and 22 to 50 lbs (30 to 45 inches) and riding forward-facing, the WAYB Pico Travel Car Seat is an engineering marvel:
- Weight & fold: Built from aerospace-grade aluminum framing and breathable GREENGUARD Gold certified wool-blend AstroKnit mesh (with zero chemical flame retardants), the WAYB Pico weighs just 8 lbs (3.6 kg) and folds in half to 14.5 × 11.6 × 18.9 inches (
37 × 29.5 × 48 cm). - Fits in airplane overhead bins: If you choose not to use it in the airplane seat (or if you are storing it between connecting flights), the folded WAYB Pico fits right inside standard US overhead bins or slides onto your rolling carry-on handle in its backpack carry bag.
- FAA & NHTSA certified: Carries both the red FAA aircraft approval label and NHTSA FMVSS 213 motor vehicle certification, installing in rental cars or Ubers in under 60 seconds via LATCH or lap-and-shoulder belt plus top tether.
- Price: $380 MSRP (Check price at WAYB).
3. Best 2-in-1 car seat + stroller for infants (0–12 months): Doona ($550)
For babies under 1 year old (4 to 35 lbs and up to 32 inches tall), the Doona Infant Car Seat & Stroller eliminates the need to pack both a car seat and a stroller:
- How it works on travel day: Roll your baby through the airport in stroller mode, press the release lever at the aircraft door to tuck the integrated wheels underneath the shell in two seconds, and buckle the Doona directly into your baby's purchased window seat using the airplane lap belt (or gate-check it free — at 17.2 lbs, it is under American Airlines' 20 lb gate-check limit!).
- When you land: Pop the wheels out on the jetway and roll straight to the Uber pickup zone or rental car shuttle, where it installs baseless with any vehicle seatbelt.
- Watch out: Leave the heavy LATCH/ISOFIX base at home when flying; the Doona shell alone is FAA aircraft certified and installs baseless in cars.
- Price: $550 MSRP / £349 RRP (Check price at Doona).
4. Best lightweight baseless infant carriers (US & UK/Europe): Joie, CYBEX & Maxi-Cosi
If you prefer a traditional infant bucket seat that clicks onto your travel stroller via adapters:
- Joie i-Snug 2 (
7.4 lbs / 3.35 kg,$169.99 / £105): Featherweight carrier that is effortless to carry up stairs and install baseless with a vehicle 3-point belt. - CYBEX Cloud T (
9.9 lbs / 4.5 kg,$449.95 / £199.95) & Maxi-Cosi Pebble 360 Pro² (10.4 lbs / 4.7 kg,$399.99 / £259.99): Both offer ergonomic lie-flat recline positions when clicked onto a stroller frame (so your baby isn't curled in a car seat angle during long airport layovers) and install baseless using a European belt path (where the shoulder belt wraps around the back of the shell for rock-solid taxi stability).
5. When to use the FAA AmSafe CARES Harness instead of a car seat
If you are flying with a toddler aged 1 to 4 years (22 to 44 lbs and up to 40 in tall) to a destination where you do not need a car seat on the ground — such as:
- Staying on-site at Walt Disney World using Disney buses, Monorails, Skyliner, and Minnie Vans (which already include 2 Graco car seats),
- Walking from a Harbor Blvd hotel at Disneyland California,
- Taking the LIRR train and subway in New York City, or
- Boarding a cruise ship (Disney Cruise Line or Royal Caribbean),
then the 1-pound AmSafe CARES Airplane Safety Harness gives your toddler FAA-certified 4-point upper-torso restraint on the plane and fits inside your pocket when you land. (Remember: CARES is approved for aircraft use only, never in cars, and must carry the genuine white AmSafe 14 CFR 21.8(d) label.)

FAQs
What is the lightest FAA-approved convertible car seat for flying?
The Cosco Scenera NEXT weighs just 6.8 lbs (3.1 kg), measures 17 inches wide, costs $59, and is FAA certified for both rear-facing (5–40 lbs) and forward-facing (22–40 lbs) use on airplanes and in cars.
Can the WAYB Pico car seat be used for babies under 1 year old?
No. The WAYB Pico is a forward-facing only car seat certified for children weighing 22 to 50 lbs and 30 to 45 inches tall (at least 1 year old by federal rule, and WAYB + the AAP recommend waiting until age 2+ when your child transitions from rear-facing to forward-facing).
Are rotating 360-degree US car seats FAA-approved for airplanes?
Most rotating convertible car seats sold in the US (such as the Nuna Revv or Evenflo Revolve360) are not FAA-approved for aircraft because their wide rotating base cannot be tightened properly with a 2-point airplane lap belt. Always check the shell sticker for the red FAA aircraft certification text before flying, or check your everyday seat free in a padded bag and bring a $59 Cosco Scenera NEXT for the cabin.
