Child car seats on planes: five things you need to know before you fly

Find out if your car seat is allowed on the plane and more tips to travel safely

Now that pandemic-related restrictions are lifting and families can fly abroad this summer, you may be considering whether to bring your baby or child car seat with you when flying.

Sitting on a child car seat can provide a more comfortable flight for young children, but is it worth bringing your car seat with you?

Here are the five essentials you need to know before you board that flight.

1. Pros and cons of bringing your car seat


  • Taking a child car seat on a plane is more expensive as it will require you to purchase a seat for your child - generally children under two don't need to pay for a seat.
  • If you have a young baby it's also worth bearing in mind that experts recommend staying in a child car seat for no longer than two hours as they can experience breathing problems (no longer than 30 minutes is recommended in the first four weeks of a baby's life). A flatter position is considered the best position for babies to travel in, especially those who are premature, newborn and young - not only for comfort, but also to help their breathing.


  • Older children can sleep in it.
  • Being properly secured for take-off and landing will help to avoid preventable injuries as opposed to your little one sitting in your lap.
  • It means your child is safely secured in the event of turbulence.
  • You can use it travelling to the airport and when you get to the other end of your journey in a hire car or taxi - as long as you can legally use the car seat in the country you are visiting.
  • In all countries within the European Union you can use a UK car seat as long as it's approved to ECE R44.04 or UN R129 (check the label).

2. Will the airline let your car seat on?

Some child car seats are TUV approvedand will have a sticker that says 'Certified For Use in Aircraft', but that's not a mandatory requirement for taking a car seat on a plane.

Typically the car seat must:

  • Be designed to be secured by means of a lap belt
  • Have a restraining harness (some require a three-point harness)
  • Not exceed the dimensions of the aircraft seat
  • Remain secured to the airplane seat at all times during the flight
  • Must not require the use of a three-point harness to secure it to the aircraft seat

Some airlines have their own child car seats you can hire for the duration of the flight if you want to use a car seat but don't want to carry your own, however you must pre-book them in advance.

Check with your airline before you fly.

3. Will your car seat fit the aeroplane seat?

All major airlines publish the width of the narrowest and widest seats in each class so it's vital to check your car seat is compatible with the aeroplane seat before you fly.

If your car seat doesn't have airline approval or is too big for the airline's restrictions, you may be asked to check it as baggage and won't be able to use it on the flight.

Below are the narrowest seat widths of the economy seats for the most popular airlines, so you can compare at a glance to see if your car seat is suitable.

3. Speak to your airline before booking

Not all airlines will allow you to use a child car seat on the plane, even if the seat is approved for use in an aircraft, and some airlines don't allow rear-facing car seats.

It's essential to speak to your airline before you fly, and it's worth confirming the make and model of your car seat too.

Try to email ahead of time and get something in writing so you can show airline staff if queried at the gate.

4. How to install your car seat in an aeroplane

Whether your car seat is forward or rear-facing, it's essential that it's placed next to a window, so that in the event of an emergency all passengers can evacuate quickly and easily.

How to in a forward-facing child car seat on a plane

Here's our step-by-step guide to setting up a forward-facing child car seat on an aeroplane seat:

  1. Position the car seat by the window, or in the middle seat of a central row on larger planes
  2. Recline the plane seat back and place the car seat forward facing onto the plane seat
  3. Thread the plan lap belt through the holes at either side of your child's car seat
  4. Buckle the release flap towards the back of the plane seat, pull the loose end taut and raise the airplane seat back.

How to in a rear-facing child car seat on a plane

But if your car seat is rearward-facing, it's slightly different. Here's our step-by-step guide to setting up a rear-facing child car seat on an aeroplane seat:

  1. Put the car seat by the window facing the backrest
  2. Thread the belt under the guides of the car seat
  3. Buckle it and pull the loose end taut.

5. Which car seats are certified for use in aircraft?

Below are three child car seats from the full list of those that are TUV approved. Thismeans they are compatible with most aeroplane seats.

Can I also take my child's buggy on our flight?

As well as a car seat, many airlines also allow you to bring a pushchair on a plane.

Some strollers are small enough to be taken into the cabin with you, while larger buggies will need to be checked into the hold.

Find out more about airlines' pushchair policies and what pushchairs we'd recommend for flights in our guide to taking pushchairs on planes.
