Flying With a Toddler and a Car Seat: What Parents Need to Know

Traveling with a toddler already requires a surprising amount of stuff. Add a car seat to the equation and suddenly you are trying to figure out how to move a bulky piece of child safety equipment through an airport while also managing luggage, snacks, boarding passes, and an energetic toddler.

The first decision is whether you want to use your toddler's car seat on the airplane, check it with your luggage, gate-check it, or arrange another appropriate seat at your destination.

There is no single answer that is best for every family. Your child's age and size, the type of car seat you own, your destination transportation plans, and the airline you are flying all matter.

For general flight preparation, read our complete guide to flying with a toddler. You can also use our toddler carry-on packing checklist before you leave.

Should You Bring a Car Seat on the Airplane?

Many parents choose to use an appropriate approved child restraint in their toddler's airplane seat. Others prefer to check the seat and have their toddler sit directly in the airplane seat when permitted.

The right choice depends partly on whether your child has their own purchased seat and whether your particular car seat is approved for aircraft use.

Why Some Parents Use the Car Seat During the Flight

One major advantage is familiarity. Your toddler already knows how it feels to sit in that seat.

For some children, being buckled into their regular car seat clearly communicates that it is time to stay seated, much like a normal car ride.

It can also give a smaller child a more supportive seating position than the standard airplane seat.

The Disadvantages of Using a Car Seat Onboard

The biggest disadvantage is getting it onto the airplane.

Car seats are bulky. You may have to carry one through security, down the concourse, through the jet bridge, and down a narrow airplane aisle.

You also need enough room to install it properly in the assigned seat.

If you decide to use a car seat onboard, allow yourself additional time during boarding.

Make Sure Your Car Seat Is Approved for Aircraft Use

Do not assume that every child restraint can be used on an airplane.

Check the labeling on your particular seat and the manufacturer's instructions before the trip.

If you cannot tell whether the seat is appropriate for aircraft use, contact the manufacturer before traveling rather than trying to figure it out while boarding.

Check the Width of Your Car Seat

Airplane seats can be narrower than the seats in your vehicle.

Before deciding that you will use your car seat onboard, look up the dimensions of your particular seat and compare them with any seat-width information available for your aircraft or airline.

A relatively narrow travel-friendly car seat can be considerably easier to manage than a large, heavily padded everyday model.

Where Can the Car Seat Be Installed?

Airlines and aircraft have rules about where child restraints may be placed, especially when an installation could interfere with another passenger's ability to exit the row.

Do not assume you can install your car seat in any seat you choose.

Check with the airline in advance and follow the crew's instructions onboard.

Can a Rear-Facing Car Seat Be Used on an Airplane?

This depends on the specific child restraint, the child's size, the seat's instructions, and applicable airline rules.

Use the restraint only in a configuration allowed by its manufacturer and accepted for your flight.

This is another reason to review the instruction manual before arriving at the airport.

Practice Installing the Seat Before Your Trip

You do not want the first time you use an airplane seat belt with the car seat to be while a line of passengers waits behind you.

Read the manufacturer's aircraft installation instructions before the trip.

Knowing where the belt goes and how the seat tightens can make boarding much less stressful.

How Do You Carry a Car Seat Through the Airport?

This is one of the least glamorous parts of flying with small children.

You have several options.

Carry It

This works for lightweight seats and short airport walks, but it becomes tiring quickly.

Use a Car Seat Travel Bag

A travel bag gives you straps or handles and helps keep the seat contained while you are moving through the airport.

Use a Rolling Car Seat Cart

Some families attach the car seat to a small travel cart so they can roll it through the terminal instead of carrying it.

Attach It to Your Luggage

Some travel straps are designed to secure a compatible car seat to rolling luggage.

Test any system at home first. Something that looks easy in a product photo may feel completely different once your suitcase is packed.

What About Checking the Car Seat?

Checking the car seat can make traveling through the airport considerably easier because you no longer have to carry it to the gate.

The tradeoff is that the seat leaves your possession and is handled as checked baggage.

If you plan to check your car seat, look at your airline's current rules before the trip so you know where to take it and whether any special procedures apply.

Should You Put a Checked Car Seat in a Bag?

A travel bag can help keep straps contained and protect the seat from dirt and grime during handling.

Some bags also make the seat easier to carry through the terminal before you turn it over.

Remember that a thin fabric bag does not make a car seat immune from rough baggage handling.

What Is Gate-Checking?

Gate-checking generally means taking the item through the airport with you and turning it over near the aircraft rather than at the main baggage counter.

Whether and how a car seat can be gate-checked depends on the airline and flight.

If this is your plan, confirm the airline's current policy instead of assuming the process will be the same as it was on another trip.

Do You Need a Car Seat at Your Destination?

This question should be answered before you decide whether bringing your own seat is worth the hassle.

Think through every part of the trip:

• Rental car
• Taxi or rideshare
• Hotel transportation
• Airport shuttle
• Trips with family or friends
• Excursions
• Return trip to the airport

You may discover that you need a child restraint immediately after leaving baggage claim.

What About Renting a Car Seat?

Some rental-car companies offer child restraints, which can eliminate the need to carry your own through the airport.

The obvious advantage is convenience.

The disadvantage is that you may not know exactly which model you will receive until you arrive, and availability can vary.

If you are considering a rental seat, research the company's current policies, availability, and reservation procedures before deciding to leave yours at home.

A Lightweight Travel Car Seat Can Make a Big Difference

If your everyday car seat is extremely heavy, families who fly frequently sometimes choose a separate travel seat that is easier to carry while still meeting their child's needs and applicable safety requirements.

That can be much easier than hauling a very large seat through several airports.

Car Seat or Stroller: Which Should You Prioritize?

Fortunately, this does not always have to be an either-or decision, but carrying both can make an airport trip considerably more complicated.

A stroller can be extremely useful for getting a toddler through a large airport. A car seat may be essential once you reach the destination.

Think about which items you will use during each stage of the trip rather than simply bringing everything by default.

Keep the Car Seat Free of Extra Items During the Flight

Use the seat according to its manufacturer's instructions.

A flight is not the place to start adding unapproved cushions, positioning devices, accessories, or improvised padding.

Do Not Put Important Travel Items in the Car Seat Bag

If you check your car seat, avoid treating the car seat bag as a place to stash important things you may need during the journey.

Anything essential should remain in your normal carry-on.

That includes:

• Medication
• Diapers
• Extra clothing
• Travel documents
• Essential feeding supplies
• Your toddler's favorite comfort item

Use our complete toddler carry-on checklist for the things that should stay with you.

Take a Photo of Your Car Seat Before Checking It

If you decide to check the car seat, taking a quick photo before handing it over gives you a record of its condition before the flight.

You can also photograph identifying information or labels that might be useful if the item becomes separated from the rest of your luggage.

Label the Car Seat or Travel Bag

Make sure your contact information is attached securely.

A simple luggage tag on the travel bag can help distinguish your seat from another similar-looking bag.

Give Yourself More Time at the Airport

Everything takes a little longer when you are traveling with a toddler and a car seat.

You may need additional time to:

• Check the seat or carry it through security
• Move through the terminal
• Speak with the gate agent
• Get down the jet bridge
• Carry the seat through the airplane
• Install the seat
• Get your toddler settled

Arriving with a reasonable time cushion makes all of those steps easier.

Boarding Earlier Can Help

If your airline offers an opportunity for families with young children to board before general boarding, that extra time can be useful when installing a car seat.

On the other hand, some parents prefer to keep an energetic toddler outside the airplane as long as possible while another adult boards first with the equipment.

If two adults are traveling, dividing the jobs can work very well.

A Two-Adult Strategy

When possible, one adult can board with the car seat and carry-ons while the other stays in the terminal with the toddler for a few extra minutes.

The first adult can install the seat and organize the bags without simultaneously trying to entertain a child in the aisle.

Whether this works will depend on the airline's boarding process, but it can make the experience much smoother when available.

If You Are Traveling Alone With a Toddler

The logistics are harder, so simplify aggressively.

Try to avoid carrying unnecessary bags. Use luggage that rolls easily. Consider a car seat carrying solution that leaves your hands available to manage your child.

Before leaving home, imagine the moment when you have to move your toddler, car seat, carry-on, and personal item from the terminal onto the airplane. If the plan sounds physically impossible, reduce what you are bringing.

What to Check Before Leaving Home

Final Thoughts

Flying with a toddler and a car seat sounds intimidating because there are a lot of logistics involved, but most of the stress can be eliminated by deciding exactly what you are going to do before arriving at the airport.

Know whether the seat is coming onboard or being checked. Know how you are going to carry it. Know what transportation you will use at your destination. And make sure you have reviewed the instructions and current airline requirements before travel day.

Once those decisions are made, the car seat becomes just another part of the travel plan rather than something you are trying to figure out at the gate.
