Flying with a car seat: whether to bring it and how

Deciding whether to bring your child’s car seat on a flight is one of the more complicated parts of planning family travel. It feels like a choice between safety and convenience. On one hand, a car seat is bulky and adds a major piece of gear to carry through a busy airport. On the other, it is essential for safe car travel at your destination and can provide a secure, familiar spot for your child on the plane.

This guide walks through the key considerations to help you decide what is best for your family, and offers practical tips for getting through the airport if you choose to bring it.

To bring a car seat or not?

Bringing your own car seat offers significant peace of mind. You know its history, how to install it correctly, and your child is already comfortable in it. For babies and toddlers, using an approved car seat on the plane is the safest way for them to fly. It keeps them securely in place during turbulence and can make it easier for them to sleep.

The main drawback is the effort involved. Car seats can be heavy and awkward to manage along with luggage and children. If you do not buy a separate seat for your child, you will have to check the car seat as luggage, where it could be damaged.

Considering the alternatives

Instead of bringing your own, you could rent a car seat from a car rental company or a local baby gear rental service at your destination. This saves you the trouble of transport, but you will not know the specific model, condition, or history of the seat you receive. Another option is to buy a less expensive, lightweight car seat to be used only for travel, or to purchase one upon arrival if you are staying for a long time.

Using a car seat on the plane

Using a car seat on board gives your child a safe and familiar place to sit. It is especially helpful for toddlers who may have a hard time staying in their own airplane seat with just a lap belt. To do this, you will need to purchase a ticket for your child, even for a baby who would otherwise be allowed to fly on your lap.

Checklist for using a car seat on board

Before you commit to this option, work through these practical steps:

• Look for the label. Your car seat must be approved for use in aircraft. Look for a sticker on the seat that says in red text: “This restraint is certified for use in motor vehicles and aircraft.” This wording applies to seats certified in the United States. Seats sold in Europe may not have this specific FAA label, so check with your airline about their rules for foreign-made seats.
• Check the airline’s rules. Visit your airline’s website for their specific policies on car seats. They may have rules about where the seat can be installed (usually a window seat, so it does not block another passenger’s exit) and whether it can be used rear-facing.
• Measure your seat. Note the width of your car seat. You can often find this information on the manufacturer’s website. Compare it to the airline’s seat width, which is also usually available online. If your seat is too wide for the airplane seat, the crew may require you to check it.
• Practice installation. An airplane seat belt buckle is in a different place than a car’s. Practice buckling your car seat in using only a lap belt at home to get comfortable with how it works.

Keep in mind that booster seats, both high-back and backless models, are not approved for use during takeoff and landing. They are designed for use with a shoulder belt, which airplane seats do not have. Booster seats must be checked or carried on as luggage.

Getting the car seat through the airport

Maneuvering a car seat through check-in, security, and to the gate is often the biggest challenge. A little planning can make it much smoother.

At check-in and security

If you plan to check your car seat, it is best to protect it. Placing it in its original box or a durable, padded travel bag can help prevent damage. Many airlines check car seats without an extra charge, but policies differ, so confirm this beforehand. Ask the check-in agent to label it as a fragile item.

If you are bringing the seat to the gate, either to use on board or to gate-check, you will need to send it through the X-ray scanner at the security checkpoint. It will likely need to be removed from any stroller or travel cart and put in a bin or on the belt by itself. For more details, see our guide to getting through airport security with a toddler.

Carrying the car seat

There are several ways to make carrying the seat easier:

• Use a stroller. Some travel systems allow the car seat to click directly onto the stroller, which is often the easiest method for babies. For older children in convertible seats, you might place the car seat in the stroller’s seat and have your child walk.
• Use a luggage cart. Airports provide luggage carts that you can use to transport the car seat along with your other bags.
• Use a car seat travel cart. You can find small, wheeled carts designed specifically for attaching a car seat. This turns the car seat into its own stroller, and your toddler or preschooler might even be able to ride in it.
• Use a travel strap. Some straps allow you to attach the car seat to your rolling carry-on suitcase, letting you pull both with one hand.
• Carry it in a bag. A backpack-style car seat travel bag frees up your hands, though it can be heavy.

Gate-checking your car seat

If you are not using the car seat on board but want to minimize the risk of damage, you can gate-check it. This means you carry it all the way to the gate, and airline staff take it from you on the jet bridge to load it onto the plane. It is usually returned to you at the aircraft door or with the checked bags at your destination; ask the gate agent which applies.

To gate-check, get a tag from the agent at the gate before you board. Place the seat in a protective bag to keep it clean and prevent straps from snagging. This is a good option for families who did not purchase a seat for a baby but want their own car seat for use at the destination, especially if they are planning any long car journeys with toddlers.

When to call your pediatrician

Travel can expose children to new germs and situations. While car seat safety is about preventing injury, it is always wise to be prepared for common travel illnesses or accidents.

Get help right away

In case of a serious injury or illness during your travels, call local emergency services or go to the nearest emergency department. Seek immediate medical care for any of these signs:

• Any injury to the head, especially if followed by vomiting, confusion, or unusual sleepiness.
• Trouble breathing or very rapid breathing.
• A fever in a baby under three months old.
• Signs of dehydration, such as a dry mouth, crying without tears, or significantly fewer wet diapers than usual.
• A seizure.
• Unusual drowsiness or being very difficult to wake up.

Talk to your pediatrician before you travel

It is helpful to schedule a visit with your pediatrician before an international trip or if you have any health concerns. Discuss these topics:

• Any questions about managing your child’s existing health conditions while away.
• Advice for a travel first-aid kit that is appropriate for your child’s age.
• Information about any recommended vaccines for your destination.
• A plan for what to do if your child gets a fever or other common illness.

Remember that emergency numbers and access to medical care can be very different in other countries. Before you leave, find out how to contact local medical services at your destination.
