This means you get years of use from a single purchase, saving you money and hassle.

Buyer’s Guide: 3 Key Factors to Consider
Certification is Key
For flights, you need a car seat that is certified for aircraft use. Look for a label that says, “This restraint is certified for use in motor vehicles and aircraft.” This is often found on the seat itself and is your green light from the FAA.
Size and Weight for Portability
Consider how you’ll be moving the seat through the airport. A lighter, more compact seat is far easier to carry and install in a cramped airplane seat. Measure the seat’s width to ensure it will fit in a standard aircraft seat, which is typically about 16-18 inches wide.
Ease of Installation
You’ll be installing the seat in a tight space, potentially while managing a child. Practice at home first! Seats that use the airplane seat belt for installation (rather than a base) are often simpler. Look for features like a built-in lock-off to securely fasten the belt.
Frequently Asked Questions
Q1: Is a car seat required on an airplane?
A1: While the FAA strongly recommends using a certified car seat for children under 40 pounds, it is not legally required. You can choose to have your child as a “lap infant,” but for maximum safety during turbulence, a car seat is the best option.
Q2: Can I use any car seat on a plane?
A2: No. Only car seats that are specifically certified for aircraft use are permitted. Check your seat for a label that states it is approved for use in motor vehicles and aircraft. Seats that are too wide may also not fit in the airplane seat.
Q3: Should I buy a seat for my toddler on a flight?
A3: Yes, if it fits your budget. Purchasing a seat for your toddler and using their car seat is the safest way for them to fly. It also provides a familiar, comfortable space for them to sit and sleep, making the journey easier for everyone.
Q4: What’s the difference between a travel car seat and a regular one?
A4: Travel car seats are specifically designed for portability. They are typically lighter, more compact, and often have features like a carrying strap or backpack. Many regular car seats are also certified for flight but can be bulkier and heavier to carry through an airport.
Q5: How do I secure the car seat on the plane?
A5: You secure it using the airplane’s lap belt. Thread the seat belt through the car seat’s designated belt path (the same one you’d use in a car) and buckle it. Tighten it firmly so the car seat does not move more than an inch side-to-side.
Final Verdict: Which One Should You Buy?
Choosing the right car seat for your flight ultimately depends on balancing portability, ease of use, and your child’s comfort. For frequent flyers seeking the lightest option, the Cosco Scenera Next is unbeatable. For parents wanting a familiar, full-featured seat that doubles as a stroller, the Doona is a game-changer. Assess your primary travel needs, and you’ll ensure a smoother journey for your entire family.
