Can You Bring a Car Seat on a Plane? Yes, Often Free

Yes, car seats are allowed on planes. You can use a car seat in the aircraft cabin for your child, or check it in the hold. Most airlines allow parents to gate-check a car seat for free, even on carriers that normally charge for checked baggage. Here is what you need to know before you fly.

Gate-Checking: The Most Common Approach

Gate-checking is the standard practice for car seats. It works like this: you keep the car seat with you through the airport, use it in the terminal and during boarding, then fold it up at the aircraft door and hand it to ground staff. It travels in the cargo hold and is returned to you at the jet bridge when you land — you collect it before reaching the terminal, not at the baggage carousel.

Most airlines allow gate-checking a car seat at no charge, even if they ordinarily charge for hold baggage. This includes many budget carriers that otherwise have strict bag fee policies. The free gate-check policy is widely applied because car seats are considered essential safety equipment for infants and young children.

Always verify the specific policy with your airline before travel, as it varies. Call ahead or check the airline's website under family travel or special items.

Using a Car Seat in the Cabin

If you have purchased a seat for your child on the aircraft, you can bring an approved car seat into the cabin and use it during the flight.

Certification matters. In the US, the car seat must be FAA-approved. The easiest way to check: look for the label that reads "This restraint is certified for use in motor vehicles and aircraft." If your car seat has that label, it is approved for use on US-registered aircraft. In the UK and EU, the equivalent certification is EASA approval.

Not all car seats are aircraft-certified. Some infant seats and budget car seats only carry road-use certification. If your seat does not have the aircraft certification label, you cannot use it in the cabin — but you can still gate-check it and use it at your destination.

Positioning in the cabin. Car seats must be placed at a window seat. They cannot be placed at an aisle seat (to keep the aisle clear for evacuation) and cannot be placed in an exit row. The car seat must face the correct direction for your child's age and weight — rear-facing for infants, forward-facing for older children where the seat allows.

Booster Seats

Booster seats present a complication. Most booster seats are not FAA-approved for use in aircraft because they lack the structural support to protect a child in turbulence or impact at the forces experienced in an aircraft environment. Check your specific booster seat for the FAA certification label.

If your booster seat is not aircraft-certified, gate-check it and have your child use the aircraft seatbelt. Children who have outgrown a car seat and are using a booster for road travel generally meet the weight and age requirements to use an aircraft lap belt safely.

The CARES Harness: A Practical Alternative

The CARES (Child Aviation Restraint System) harness is a FAA-approved aviation-specific harness for children weighing between 22 and 44 lbs (approximately 10 to 20 kg). It is a small, lightweight harness that attaches to the aircraft seat back and provides equivalent protection to a car seat on board.

The CARES harness is about the size of a small bag and weighs under 500g. Many families who travel frequently use it instead of bringing a full car seat onto the aircraft. At the destination, you use a rental car seat or a car seat provided by family. The CARES harness is sold directly by Kids Fly Safe and is widely available online.

Airline-Specific Policies

Ryanair and easyJet both allow one collapsible car seat per infant as a free check item at the aircraft door. The seat must be collapsible. Check current Ryanair and easyJet family travel pages before flying, as these policies are occasionally updated.

US carriers (United, American, Delta, Southwest) all allow gate-checking a car seat for free. Southwest's generous bag policy extends to car seats as well.

Long-haul airlines generally have the most accommodating policies and will often allow car seats both as cabin items and as free checked items.

Protecting Your Car Seat in the Hold

Car seats in the hold can be damaged by baggage handling equipment. If your car seat has value and you are checking it:

• Attach a luggage tag with your name and contact details
• Use a dedicated travel bag for car seats — these are inexpensive and protect against grease, dirt, and impact from baggage handling
• Consider marking the car seat with a bright ribbon or tape so you can identify it easily and confirm it has not been damaged

If a car seat is visibly damaged in transit, report it to the airline at the baggage desk before leaving the airport. Airline liability for checked items applies.
