There is no single "Austin airport car seat policy." Three sets of rules apply to your trip: the airline and FAA rules for the flight, TSA rules at the checkpoint, and Texas law for the ride to and from Austin-Bergstrom International Airport (AUS). Car seats usually travel free as checked or gate-checked baggage, the FAA recommends one on board for children under 2, and Texas exempts for-hire vehicles such as limousines from its child seat law. Exempt does not mean safe to skip, and the details are below.
TL;DR
- Airlines generally let you check a car seat at no charge, and AUS says car seats, strollers and bassinets are usually accepted without a fee. Confirm with your airline.
- The FAA does not require a car seat on a plane, but it advises an approved restraint for children under 2. Your seat needs a ticket for the child and a label saying it is certified for aircraft use.
- Texas law requires children under 8, unless taller than 4 feet 9 inches, to ride in a child passenger safety seat system. Vehicles for hire, including limousines, are exempt, so the seat has to be arranged by you or your provider.
- Ask for the seat type you need when you book the ride, and get the answer in writing.

What the airline and the FAA require for the flight
The FAA does not require children to ride in a car seat on a commercial flight. Children under 2 can fly as lap children at no cost on most domestic flights, according to the FAA Kids' Corner. The agency still says the safest place for a child under 2 is an approved child restraint system, not your lap, because your arms cannot hold a child securely through unexpected turbulence.
The American Academy of Pediatrics makes the same point in its child passenger safety guidance, noting that the FAA exempts children under 2 from the seat requirement.
The catch is simple. A lap child has no assigned seat, so there is nowhere to install a car seat. To use one on board, you must buy a ticket for your child. The airline is not obliged to hand you a free seat, even on a half-empty flight.
Is your seat approved for aircraft?
Check the label before you leave home. A hard-backed car seat must carry text saying it is certified for use in aircraft. The FAA also accepts harness-type CARES devices, which are certified for children 22 to 44 pounds and up to 40 inches tall. A CARES harness works only on the plane, never in a car.
A few placement rules apply once you board:
- The seat generally goes in a window seat.
- It cannot go in an exit row.
- It must not block another passenger's path out in an emergency.
Airlines differ on details such as rear-facing installation and whether a seat fits a particular aircraft's seat width. Check your airline's child policy and, if the seat is bulky, measure it first.
Car seats at the AUS checkpoint
TSA treats a car seat as ordinary baggage. Carried on, it goes through the X-ray machine like a bag. If it does not fit, an officer will screen it by hand. Plan for a few extra minutes and keep one hand free for your child.
The TSA's guidance for families notes that children 12 and under may accompany a TSA PreCheck-enrolled parent or guardian in the PreCheck lane. That can shorten the line when you are juggling a seat, a stroller and a diaper bag.
TSA Cares
If you want a specialist to walk you through screening, TSA Cares takes calls at (855) 787-2227. TSA recommends calling at least 72 hours before you fly. The City of Austin has a short explainer on using TSA Cares at AUS if you want to know what to expect.
Check it, gate-check it, or carry it on
| Option | Good for | Watch out for |
|---|---|---|
| Check at the ticket counter | Families who want free hands through the terminal | Damage risk, so use a padded travel bag |
| Gate-check | Strollers and seats you may need during a connection | Pick it up at the jet bridge or baggage claim, as your airline directs |
| Carry on and install | Children with their own ticket | Seat must be aircraft-certified and fit the seat |
AUS also suggests labeling strollers, car seats and other infant items with your name and phone number. Do it. Black car seats look alike on a baggage belt.
The Texas car seat law on the ride from AUS
The airport leg is where families get caught out. Texas Transportation Code 545.412 says a child younger than 8 must be secured in an appropriate child passenger safety seat system unless taller than 4 feet 9 inches. Children 8 and older must be in a seat belt. Texas DSHS lists fines of $25 to $250 for child restraint violations.
The seat must be installed according to the manufacturer's instructions, and the Texas Department of Public Safety stresses that following the seat manual matters more than age milestones alone.
Taxis, limos and hired shuttles
The Texas DPS child passenger safety FAQ says vehicles for hire are exempt from the child passenger safety law. That list includes taxis, limousines, hired shuttles and public transit buses. Many parents assume the opposite.
The law is a legal minimum. A crash does not check whether a vehicle was exempt. If your child is small enough to need a seat in your own car, they need one in a hired car too. Arrange it before you land, not curbside.
Rear-facing, forward-facing and boosters
The Texas Department of Transportation publishes the state's seat belt and car seat guidance. The practical rule from Texas safety experts is to keep children rear-facing until they reach the highest weight or height limit of their seat, and ideally until at least age 2. Read your manual, because the seat's limits matter more than a birthday.
When you pick a ride at AUS, ask yourself which stage your child is in: infant seat, convertible, harness, or booster. Then say so plainly when you book.
Three ways to get a seat to and from AUS
- Bring your own. You know it, it fits your child, and you know its history. The cost is hauling it through the terminal and installing it quickly in an unfamiliar vehicle.
- Rent one at your destination. Some rental companies and baby gear services deliver seats. Inspect it for an expiration date, a visible crash history and a complete manual.
- Ask your chauffeur company to supply one. Good providers can often arrange a seat by request, but this varies by company, so confirm the type, the stage and the installation before the day.
Whichever you choose, avoid the unplanned option: showing up at the curb and asking the driver to improvise.
What to ask a limo or black car company before you book
Use this list when you call or email. A professional operator will not mind a long list of questions about a child.
- Can you provide a seat for my child's age, weight and height? Give exact numbers, not just "a toddler."
- Rear-facing or forward-facing, and which brand or type? Make sure it matches your child's stage.
- Who installs it? If you install your own seat, ask whether the driver can help check it.
- Which vehicle will I get? A sedan, an SUV and a van have different seat belt and latch layouts, and rear-facing seats take room.
- How many seats and passengers in total? A family of five with two car seats and luggage needs more than a sedan.
- How will you track my flight? Delays are common with children, and a pickup tied to the real landing time saves you waiting.
- Is the price flat? Ask about extra charges for waiting time, child seats or additional stops.

Choosing the right vehicle for a family
Luggage, a stroller and one or more seats take up more space than most people expect. Our published starting hourly rates, from our fleet page, give a feel for the options:
| Vehicle | Starting rate | Best for |
|---|---|---|
| Executive Black Sedan | from $120 per hour | One child seat, two adults, light luggage |
| Luxury Black SUV | from $160 per hour | Families with a seat and a stroller |
| Executive Sprinter Van | from $175 per hour | Larger groups, multiple seats, more luggage |
| Classic Stretch Limousine | from $195 per hour | Celebrations and larger parties |
| SUV Stretch Limousine | from $275 per hour | Groups wanting space and comfort |
| Party Bus | from $350 per hour | Large events |
For most families coming through AUS with young children, an SUV or a van gives you the best room for a seat and the luggage that comes with it. Tell us your headcount and your child's seat requirements, and we will help you match the vehicle.
Our perspective: plan the ground leg like the flight
Families spend weeks sorting out a flight, then leave the ride from the airport to chance. We see the same pattern repeatedly. Parents assume a limousine or black car comes with everything a child needs, or assume the law will force someone to sort it out. Because for-hire vehicles are exempt in Texas, nobody is forced to, so the conversation has to happen at booking.
Our approach is to treat the airport transfer as a plan, not a pickup. We track your flight, build in buffer time, and use flat-rate pricing with no surge fees, so a delayed landing with a tired toddler does not turn into a pricing surprise. If your trip includes a child seat requirement, tell us when you reserve, with your child's age, weight and height, and we will confirm the arrangement with you before the day.
The seat itself is your decision: the right one is the one that fits your child and your vehicle, installed the way the manual says. A chauffeur's job is to make everything around it calm.

Getting your seat checked before you travel
A seat that is installed wrong protects less than you think. Austin Public Health offers free car seat safety inspections by appointment, in partnership with Dell Children's Medical Center. Appointments are held at neighborhood centers such as Dove Springs and South Austin. Registration typically opens on the Monday, 8:00 a.m., two weeks before the event, so book early if you are a local family getting ready for a trip.
If you are visiting and staying in a rental, ask your host about nearby stores and inspection options. Many travelers book owner-listed vacation rentals in Austin, and a short message to the owner before you arrive can tell you how far the house is from the airport and whether the driveway has room to install a seat comfortably.
A simple timeline for families flying through AUS
- Two to four weeks out: Check your seat's label and expiration date. Decide whether it flies with you or stays behind. Buy your child a ticket if you want to use a seat on board.
- One to two weeks out: Book your ground transportation and state your child's seat needs. Get confirmation in writing.
- At least 72 hours out: Call TSA Cares if you want help at the checkpoint.
- The day before: Label the seat and stroller. Pack the manual or photograph the installation pages.
- Arrival day: Meet your driver, install the seat before pulling away, and confirm the harness is snug.

FAQ
Does a toddler have to be in a car seat on a plane?
No, the FAA does not require it. A child under 2 can fly on your lap on most domestic flights, but the FAA recommends an approved restraint because arms cannot reliably hold a child through turbulence. To use a seat on board, you need to buy a ticket for your child.
Can I check a car seat for free at Austin airport?
Usually yes. AUS says airlines typically accept a car seat, stroller or bassinet without charge in addition to checked luggage, but each airline sets its own rules. Confirm with yours before the trip, and use a padded bag to protect the seat.
Does a limo in Texas have to provide a car seat?
No. Texas law exempts vehicles for hire, including limousines and taxis, from the child passenger safety law. That makes it your job to ask for a seat when booking, and to confirm the type before the day.
What are the Texas car seat rules by age?
Children younger than 8 must ride in a child safety seat system unless they are taller than 4 feet 9 inches, per Texas DSHS. Children 8 and older must use a seat belt. Fines run from $25 to $250, and the seat must be installed according to its manual.
Can a CARES harness be used in a car?
No. CARES devices are approved for aircraft only, for children 22 to 44 pounds and up to 40 inches tall. You still need a proper car seat for the ride to and from the airport.
