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

Sitting on a child car seat can provide a more comfortable flight for young children.

If you’re going away this summer and considering bringing a baby or child car seat with you, here are the five essentials you need to know before you board that flight.


Compare all the best child car seats we’ve reviewed.


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.

But taking your child car seat on a plane can be very practical for a number of reasons.

  • 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 approved and 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 5-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.

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

But if your car seat is rearward-facing, it’s slightly different:

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

Car seats with narrow widths ideal for flights

These car seats are narrow and relatively light, so you won’t be struggling with carrying a bulky and heavy infant seat through a busy airport.

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.
