Flight-Approved Car Seats: What the FAA Actually Requires

A car seat is safe to bring on a plane if it meets one of two FAA standards: it bears a label stating it is approved for aircraft use, or it is a model the FAA has tested and listed on its official database. The label is the easiest route — manufacturers print it directly on seats that pass FAA crash testing. If your seat has no label, you can check the FAA's list of approved models by manufacturer and model number on its website. The airline does not decide whether your seat is safe; the FAA does, and that decision does not change from one airline to another.

You do not need to buy a special airplane car seat. Most standard car seats sold in the United States meet FAA standards already. The confusion arises because the label is small, often on the back or bottom of the seat, and many parents never see it. If you own a car seat made in the last ten years by a major manufacturer, it is very likely approved — but you should verify before you book, because you cannot use an unapproved seat on the plane, and the airline will not let you gate-check it as luggage.

Key Takeaways

  • An FAA-approved car seat must have a label stating it is approved for aircraft use, or be listed on the FAA's official database of tested models.
  • You can bring an approved car seat on the plane and use it in your assigned seat, but you must purchase a ticket for the child — the seat cannot occupy a seat for free.
  • If your car seat is not approved, you cannot use it during flight, and most airlines will not allow you to check it as luggage because it may be damaged in handling.
  • The FAA maintains a searchable list of approved car seats by manufacturer and model number on its website, updated as new models are tested.
  • Booster seats and backless boosters are generally not approved for aircraft use; only forward-facing and rear-facing car seats with harnesses meet FAA standards.

How to learn about Your Specific Car Seat Is Approved

Start by looking for the approval label on your car seat itself. Manufacturers place it in different locations — check the back of the seat, underneath, along the side, or on the instruction manual. The label will say "This restraint is certified for use in motor vehicles and aircraft" or similar language. If you find this label, your seat is approved and you are done.

If there is no label or you cannot locate it, visit the FAA's website and search their database of approved child restraint devices. You will need the manufacturer name and the exact model number. The model number is usually on a sticker or tag attached to the seat frame. Search results will tell you whether that specific model passed FAA testing. The database is free and does not require registration.

If your seat does not appear in the database and has no label, it is not approved for aircraft use. This is common with older seats, seats made outside the United States, and some budget models. In this case, you have two options: purchase an approved seat before your trip, or plan to hold your child in your lap during flight (which is legal but not recommended by safety experts).

What Happens When You Bring an Approved Seat to the Airport

You must purchase a ticket for your child in order to use the car seat on the plane. The seat occupies a full passenger seat, so the child cannot sit in your lap while the seat is installed. Airlines do not charge extra for the seat itself, but you pay the standard child fare for that seat. If you are flying with a lap child and decide to use the car seat instead, you will need to buy an additional ticket at the gate or online before departure.

At the airport, inform the airline staff at check-in or the gate that you are traveling with an approved car seat. They will note it in your reservation. When you board, install the seat in the assigned row using the airplane seat belt or the LATCH system if the airplane seat has LATCH connectors (most do not). The seat must be installed in a forward-facing position; rear-facing seats are not permitted on aircraft because they obstruct the aisle or other passengers' legroom.

After landing, you can either gate-check the seat or carry it off the plane. Gate-checking means the airline takes it at the door and loads it into the cargo hold for the flight, then returns it to you at baggage claim. This protects the seat from damage during regular baggage handling. If you carry it on, you are responsible for any damage that occurs during flight.

Booster Seats and Why They Are Not Approved

Booster seats — both high-back and backless models — are not approved for aircraft use by the FAA. A booster seat works by lifting the child so the airplane seat belt fits correctly across the chest and lap. On an airplane, the seat belt is designed to work with the airplane's own restraint system, and a booster seat interferes with that fit. The FAA has not tested booster seats for aircraft safety and does not permit them.

If your child uses a booster seat in the car but is old enough to sit without one on a plane, you can use the airplane seat belt alone during flight. The FAA allows children to use the standard airplane seat belt if they are at least 2 years old and weigh at least 40 pounds. If your child does not meet those thresholds, you must use a forward-facing car seat with a harness, or hold them in your lap.

Checking Your Seat Before You Travel

Before you arrive at the airport, inspect your car seat for damage. Look for cracks in the plastic shell, bent metal parts, or torn fabric. If the seat has been in a car accident, even a minor one, it should not be used on a plane — the impact may have compromised its structure in ways you cannot see. The same applies if the seat has been dropped from a height or sat on heavily.

Test the seat belt or LATCH attachment to make sure it works smoothly. On the plane, you will need to install the seat quickly, and a stuck or broken mechanism will delay boarding. If you have not used the seat in several months, practice installing it at home using your car's seat belt, so you know how it works before you are at the gate.

Check the expiration date on the seat if it has one. Most car seats do not expire, but some manufacturers print an expiration date on the label. If your seat has passed its expiration date, it is no longer approved for aircraft use, even if it appears to be in good condition.

What to Do If Your Seat Is Not Approved

If you discover your seat is not on the FAA list and has no approval label, you have several options. The fastest is to purchase an approved seat before your trip. Many approved models cost between $100 and $300 and are available at major retailers. If you are traveling soon and cannot buy a new seat, you can hold your child in your lap during flight, which is legal for children under 2 years old. For children 2 and older, holding them is not recommended by safety experts, but it is permitted.

Some parents rent a car seat at their destination instead of traveling with one. Car rental companies and third-party rental services offer approved seats for a daily fee, usually $10 to $15 per day. This works if you need a seat only for ground transportation at your destination and do not need one on the plane itself.

Do not attempt to use an unapproved seat on the plane. Flight attendants are trained to spot unapproved seats, and the airline will ask you to remove it. If you refuse, you may be denied boarding. The seat cannot be gate-checked or placed in the overhead bin as a workaround — it must either be used correctly or left behind.

Frequently Asked Questions

Can I use a car seat I bought outside the United States?

Only if it appears on the FAA's approved list. Car seats sold in other countries may not meet FAA standards, even if they meet European or other safety standards. Check the FAA database before you travel. If your seat is not listed, you cannot use it on a U.S. flight.

Do I have to buy a ticket for my lap child if I want to use a car seat?

Yes. The car seat occupies a full passenger seat, so you must purchase a ticket for that seat. You cannot use the car seat and keep the child in your lap at the same time. If you are flying with a lap child and decide to use the seat, you will need to buy an additional ticket.

What if the airplane seat does not have a seat belt?

All commercial airplane seats have seat belts. If you cannot find it, ask a flight attendant — it may be tucked into the seat cushion or under the armrest. The seat belt is required to install the car seat, so do not board without locating it first.

Can I use a car seat in the bulkhead row or exit row?

Most airlines do not permit car seats in exit rows because they may obstruct evacuation. Some airlines also restrict them in bulkhead rows because the seat may not fit properly or may block the flight attendant's work area. Check your airline's policy when you book, or call ahead to confirm where you can install the seat.

What happens if my car seat gets damaged on the plane?

If you gate-check the seat and it is damaged by the airline, you can file a claim with the airline's baggage department. If you carry it on and it is damaged during flight or boarding, the airline is usually not liable because you chose to keep it with you. Gate-checking is the safer option if you want to protect your seat from damage.
