Which car seats the FAA allows on planes

The Federal Aviation Administration (FAA) permits certain car seats on commercial flights, but not all of them. A car seat must carry a label stating it is approved for use on aircraft — this label is usually on the seat itself or in the manual. The seat also has to fit in a standard airplane seat without blocking the aisle or emergency exits, and you must purchase a ticket for the child to occupy that seat.

Most major car seat brands make models with FAA approval. The approval means the seat has been tested to withstand the forces of flight and can be safely secured with an airplane seatbelt. However, approval does not mean the airline is required to let you use it — each airline sets its own policies about whether car seats are permitted in the cabin, so you should check with your specific airline before you book.

Key Takeaways

  • An FAA-approved car seat must have a label on the seat or in the manual stating it is approved for aircraft use.
  • The car seat must fit within a standard airplane seat and not block aisles or emergency exits.
  • You need to purchase a separate ticket for your child to use a car seat on the plane.
  • Airlines have different policies on car seats, so contact your airline before traveling to confirm they allow them in the cabin.
  • Car seats are not permitted in exit rows, and some airlines restrict them to certain cabin sections.

How to check if your car seat is FAA-approved

Look for a label on the car seat itself that says "This restraint is certified for use in motor vehicles and aircraft" or similar wording. The label is usually on the side or back of the seat. If you cannot find a label on the seat, check the user manual — the approval statement should appear in the first few pages or in a section about air travel.

If you have lost the manual, visit the manufacturer's website and search for your specific model number. Most manufacturers list which models are FAA-approved in a table or downloadable document. You can also contact the manufacturer's customer service line directly with your seat model and serial number, and they will tell you whether it is approved.

Do not assume a newer or more expensive car seat is approved just because it is a well-known brand. Approval is model-specific, not brand-wide. A manufacturer may make some approved models and some that are not approved for aircraft.

What happens at the airport when you bring a car seat

Arrive at the airport with your car seat in hand or in a car seat travel bag. At check-in, tell the agent you are bringing a car seat into the cabin. The agent will note this on your reservation. You do not need to show the FAA approval label at check-in, but having it visible or being able to describe it can speed things up if there is any question.

At the gate, before boarding, the gate agent may ask to see the car seat or the approval label. This is normal and happens at some airlines more than others. If the agent questions whether the seat is approved, show them the label or the manual page with the approval statement. If there is any doubt, the airline may not allow the seat on the plane, so having documentation ready prevents delays.

Once you board, you will install the car seat in the airplane seat using the airplane seatbelt, not the car's LATCH system. The seatbelt threads through the car seat's belt path, and you tighten it the same way you would in a car. Airplane seatbelts work differently from car seatbelts, so take a moment to read the airplane seat's instructions if you are unfamiliar with how they work.

Restrictions and rules that vary by airline

Some airlines do not permit car seats in the cabin at all, even if they are FAA-approved. Other airlines allow them but restrict them to certain rows — for example, not in exit rows or bulkhead rows where the seat might not fit properly. A few airlines charge a fee to use a car seat, though this is uncommon.

The safest approach is to contact your airline directly before you book or at least 48 hours before your flight. Call the airline's customer service line or use their website chat to ask: "Can I bring an FAA-approved car seat in the cabin?" Write down the name of the agent you spoke with and the date, in case there is confusion at the airport.

If you are flying with a lap child (a child under 2 years old who does not have a ticket), you cannot use a car seat in the cabin — the child must sit on your lap during flight. Some parents choose to purchase a ticket for a lap child specifically so they can use a car seat, which is permitted.

Installing a car seat on an airplane

Airplane seatbelts are simpler than car seatbelts and work in only one way. The belt has a metal buckle on one end and a slot on the other. Insert the buckle into the slot until you hear a click, then pull the loose end of the belt to tighten it. The belt should be snug across the car seat's belt path — the same path you would use in a car.

Do not use the car seat's internal harness straps to find the seat to the airplane seat. The airplane seatbelt alone is what holds the car seat in place during flight. The car seat's harness is for your child to wear while sitting in the seat, just as it would be in a car.

If the car seat does not fit in the airplane seat without blocking the aisle or armrests, or if the seatbelt does not thread through the belt path properly, the airline may ask you to gate-check the seat (store it in the cargo hold) or not allow it on the plane. Test the fit before you travel if possible, or arrive early enough at the gate to troubleshoot.

Alternatives if your car seat is not approved or does not fit

If your car seat is not FAA-approved or does not fit in the airplane seat, you have a few options. You can purchase a car seat designed specifically for air travel — these are smaller and lighter than standard car seats and are built to fit in airplane seats. Brands like CARES and some models from major manufacturers make travel-specific seats that are FAA-approved.

You can also gate-check your car seat, meaning you bring it to the gate and the airline stores it in the cargo hold during flight. The seat travels free and is returned to you when you land. This is a common option for families who want to use their regular car seat at their destination but do not want to use it on the plane itself.

If your child is old enough, you can use a booster seat instead, though booster seats have the same FAA-approval requirement as car seats. Some airlines also allow children to sit with a seatbelt extender if they are tall enough, though this is less safe than a car seat and is not recommended by child safety organizations.

What to do if the airline denies your car seat at the gate

If an airline agent tells you your car seat cannot go in the cabin, ask why — the reason matters. If it is because the seat does not fit, you can try a different seat location or ask about gate-checking it. If it is because the airline says the seat is not approved, ask to see their policy in writing and show them the FAA label on your seat.

If there is a genuine disagreement about whether the seat is approved, ask to speak with a supervisor. Bring the approval label or manual page with you. Most disagreements are resolved quickly once the label is visible, because the airline's policy is to allow FAA-approved seats.

If the airline still refuses and you believe they are wrong, you can file a complaint with the FAA after your trip. However, the fastest resolution at the airport is usually to gate-check the seat and move forward with your flight, then contact the airline's customer service afterward if you want to dispute the decision.

Frequently Asked Questions

Do I have to buy a ticket for my child to use a car seat on the plane?

Yes. A car seat takes up a full airplane seat, so your child must have their own ticket. If your child is under 2 years old and you do not purchase a ticket, the child sits on your lap and cannot use a car seat in the cabin. Some parents purchase a ticket for a lap child specifically to use a car seat.

Can I use a car seat in the exit row?

No. Exit rows have different safety requirements, and car seats are not permitted there. The airline will assign you a regular seat if you request a car seat, or you can ask for a different seat location if the one assigned is an exit row.

What if my car seat does not fit in the airplane seat?

If the seat is too wide or the seatbelt does not thread through the belt path, the airline may ask you to gate-check it. Gate-checking means the seat travels in the cargo hold and is returned to you when you land. You can also consider a travel-specific car seat, which is smaller and designed to fit in airplane seats.

Can I use a booster seat instead of a car seat on a plane?

Only if the booster seat is FAA-approved and fits in the airplane seat. Booster seats have the same approval requirements as car seats. However, child safety organizations recommend car seats over booster seats for air travel when possible.

What if the airline says my approved car seat is not allowed?

Ask the agent to explain why and request their policy in writing. Show them the FAA approval label on the seat. If there is still disagreement, ask for a supervisor. Most issues are resolved once the label is visible. If the airline continues to refuse, you can gate-check the seat and file a complaint with the FAA after your trip.
