Are car seats required on airplanes?

No, car seats are not federally required on airplanes for children over age 2. Children under 2 can travel as lap infants without a separate seat. However, the FAA strongly recommends all children be secured in an FAA-approved car seat or aircraft-approved restraint during takeoff, landing, and turbulence. Turbulence is the leading cause of injuries to children on aircraft, and unrestrained children become projectiles during unexpected severe turbulence. For children under 40 pounds, a car seat provides significantly better protection than lap belts alone.

How do I know if my car seat is FAA-approved?

All car seats approved for aircraft use have a label stating: "This restraint is certified for use in motor vehicles and aircraft." This label is typically on the side or back of the car seat near the manufacturing date. If your seat doesn't have this specific label, it is NOT FAA-approved for use on aircraft. Most convertible and forward-facing car seats sold in the US are FAA-approved, but always verify before traveling. Booster seats are NOT approved for aircraft use as they require shoulder belts that airplanes don't have.

Do airlines charge for bringing a car seat?

No, airlines in the United States cannot charge fees for checking or carrying on FAA-approved car seats or strollers. This is federal regulation. Car seats can be: 1) Used on the aircraft in a purchased seat at no extra charge beyond the ticket, 2) Gate-checked free of charge, 3) Checked at the ticket counter free of charge. Airlines also allow one stroller to be gate-checked per child at no charge. Note: While free, gate-checked and checked car seats are not guaranteed to arrive undamaged.

Should I gate-check or check my car seat?

Gate-checking is generally preferred over checking at the ticket counter. When you gate-check, your car seat stays with you until you board, reducing handling and potential damage. Gate-checked items are typically treated more carefully than luggage checked at the counter. However, gate-checking means carrying the car seat through security and the airport. If you have a dedicated travel car seat or protective bag, checking at the counter may be easier. Never check your child's primary car seat if you can avoid it - damage may not be visible but can compromise safety.

How do I install a car seat on an airplane?

Installing a car seat on an airplane follows similar principles to vehicle installation: 1) Use the airplane seat's lap belt only (no LATCH on aircraft), 2) Route the lap belt through the forward-facing belt path on your car seat, 3) Buckle and tighten until the seat moves less than 1 inch, 4) Ensure the car seat doesn't block any passenger's access to the aisle. Window seats are preferred for car seat installation so they don't block other passengers. Bulkhead rows often have fixed armrests that can prevent proper car seat installation - avoid these rows if possible.

Flying with a Car Seat 2026: FAA-Approved Guide & Tips

Air travel with children presents unique challenges for safety-conscious parents. While children under 2 can legally travel as “lap infants,” the FAA and safety experts strongly recommend securing children in FAA-approved car seats during all phases of flight.

Here’s what we’ll cover: FAA approval requirements, installation procedures, airline policies, and the best travel-friendly car seats available in 2026.

Why Use a Car Seat on an Airplane?

Turbulence Protection

Turbulence is the leading cause of injuries to children on aircraft. During unexpected severe turbulence, unrestrained children can become projectiles, suffering serious injuries. A properly installed car seat keeps your child secure during these unpredictable events.

Takeoff and Landing Protection

The most dangerous phases of flight are takeoff and landing. Car seats provide crash protection during aborted takeoffs, hard landings, and runway incidents - events where lap-held children face severe injury risks.

Peace of Mind

Travel is stressful enough without worrying about your child’s safety. A familiar car seat provides consistency and security in an unfamiliar environment.

FAA Regulations and Requirements

Here’s how the regulatory landscape breaks down. The FAA allows children under 2 to travel as lap infants, but strongly recommends car seats for optimal protection. Any seat used on board must bear the FAA approval label confirming aircraft certification. The AAP goes further, recommending car seats on aircraft through age 4 and 40 pounds. NHTSA data backs this up — children under 40 pounds should be restrained whenever possible. One thing that catches parents off guard: the FAA doesn’t require car seats for children over 2, but airlines can’t charge you for bringing an approved one.

FAA certification label on car seat confirming approval for aircraft use

FAA Approval: What You Need to Know

The Approval Label

Every car seat approved for aircraft use carries a specific label stating:

“This restraint is certified for use in motor vehicles and aircraft.”

This label is typically found on the side or back of the seat, near the manufacturing date.

Which Seats Are Approved?

Approved:

Most convertible car seats
Most forward-facing seats with harness
Travel-specific car seats (WAYB Pico, etc.)

NOT Approved:

Booster seats (require shoulder belts airplanes don’t have)
Vest-style restraints like the Ride Safer Travel Vest (unless specifically aircraft-approved)
Car beds (special medical devices only)

Booster Seats on Airplanes

Booster seats cannot be used on aircraft because they require lap-and-shoulder belts. Airplane seats only have lap belts. Children who normally use booster seats should either:

Use an FAA-approved 5-point harness seat on the plane
Use the airplane lap belt properly adjusted
Use a CARES harness (Child Aviation Restraint System)

Airline-Specific Policies

FAA regulations set the baseline, but individual airlines can add their own policies on top. Most domestic carriers allow FAA-approved car seats in any purchased seat, though some restrict usage to window seats. Budget carriers may have more restrictive policies regarding dimensions and placement. Some international airlines won’t recognise certain foreign-approved seats at all. Always contact your specific airline before travel to confirm their current policies — don’t assume what worked on one airline will fly (literally) with another.

Installation on Aircraft

Step-by-Step Installation

Raise the airplane seat armrest (if movable)
Position the car seat rear-facing or forward-facing as appropriate
Route the lap belt through the car seat’s belt path
Buckle and tighten until the seat moves less than 1 inch
Test the installation by pushing and pulling at the belt path

Differences from Vehicle Installation

No LATCH system: Aircraft don’t have lower anchors
Lap belts only: No shoulder belts to work with
Narrower seats: Some car seats may not fit
Different seat angles: May affect recline positions

Troubleshooting

Seat is too loose:

Ask a flight attendant for a seat belt extender
Try a different aircraft seat
Consider your car seat may be too wide

Seat doesn’t fit:

Some aircraft seats are narrower than 16 inches
Bulkhead seats often have fixed armrests
Try moving to a different row

Gate-Checking Safety

Gate-checking your car seat? A few steps protect it from damage. Use a protective travel bag designed for car seats — rough handling is the norm, not the exception. Remove any loose attachments or accessories before checking. Label the seat clearly with your name and contact information.

When you get it back, inspect it carefully. Cracks, stress marks, or damaged padding mean you shouldn’t use the seat. Any damage could compromise safety, and you won’t always be able to see internal issues. If something looks off, don’t risk it.

Gate-Checking vs. Checking at Counter

Gate-Checking Advantages

Reduced handling (less damage risk)
Access to seat until boarding
Typically loaded last/unloaded first
More careful treatment by ground crew

Counter-Checking Advantages

Don’t carry through airport
Can use stroller/cart until check-in
Less to manage at security

Damage Risks

Checked car seats face significant damage risks:

Rough baggage handling
Compression damage in cargo holds
Exposure to weather/extreme temperatures
Loss or misrouting

Recommendation: If you must check a car seat, use a protective bag and consider it “damaged until proven otherwise.” Inspect thoroughly before use.

International Travel Considerations

International travel adds a layer of complexity. Your FAA-approved seat will be recognised by most international carriers, but “most” isn’t “all.” Some foreign airlines won’t accept non-local-approved seats, and European carriers often have stricter policies regarding dimensions and placement than US domestic flights.

Research your destination country’s car seat laws for ground transportation — some nations require children to use locally approved seats in vehicles, which could catch you out. Bring documentation proving your seat’s approval status. And don’t assume the rules are the same in both directions; the airline you fly out on may have different policies than the one bringing you home.

Alternative Restraint Options

CARES Harness

For children 22-44 pounds who have outgrown car seats but still need restraint, the CARES harness is an FAA-approved alternative:

Weighs just 1 pound
Attaches to the airplane seat directly
Approved for all phases of flight
NOT for use in vehicles

For older children who’ve outgrown car seats but still benefit from extra restraint, the CARES harness is a solid alternative. It wraps around the airplane seat back and connects to the lap belt, creating a four-point restraint system. Unlike boosters, it works with airplane lap belts alone — and it carries its own separate FAA approval specifically for aviation use.

Lap Belt Use

Children over 40 pounds — typically those who’ve transitioned to a booster seat on the ground — can use the airplane lap belt alone. That said, the AAP recommends car seats on aircraft through age 4 and 40 pounds for optimal protection, so consider the CARES harness if your child falls near that boundary.
