What to Look for in The Best Travel Car Seat for 3 Year Old 

Here are some of the most important things to look at before you choose the right car seat for your toddler:

1. Using a Car Seat Overseas in Cars

Best car seat on plane for 3 year old

One of the most important things to check out for when you travel overseas with a toddler car seat is to find out what type of anchoring system is required in the country that you going to. Yes, not every country has the same way of installing the car seat. 

Some of the countries, such as Italy, have a two-point anchoring system at the base of the seat, whilst countries like Australia, have only one anchor point at the back of the seat. Choosing the right seat for the destination that you are going to can and will save you money.

Although the alternative option of hiring a car seat together with the car hire is there, the daily car seat hire price can add up and very quickly exceed the price of a brand new car seat in the first place. Something to think about here.

2. Using a Car Seat on a Plane

Does a 3 year old need a car seat on a plane? The answer is yes, and it also needs to be the right car seat! With all the different options out there, it is important to know exactly what you need to look for in the best and safest car seat for 3-year-old airplane travelers.

First of all, any toddler car seat on plane travel needs to be FAA certified. Once you find a seat with this rating, you will need to make sure it is compact, slim and lightweight. The best car seat on plane for 3 year old passengers will need to be easy to carry on board, and slim enough to comfortably fit on the seat.

From our extensive reviews of the best car seat for travel, we have found the ideal product for use on a plane with 3 year olds.

3. What to Look Out For

Here are some of the most important things to look out for:

Compact and Slim Design

When you are flying with your 3 year old and you plan to take a car seat that is best suitable for her/his weight and height, there are also other things to consider, such as the size of the actual travel car seat.

If you do your research, plane seats can vary in size from around 16″ to 22″, whilst most are around the 17 or 18″. Saying that, make sure to check out the sizes of the seats on the plane that you are flying on.

You can check to see if your plane is on a list on the SeatGuru seat chart table to see what size your seat will be ahead of time.  

Lightweight and Easy to Carry

Choosing a car seat that is both; easy-to-carry around and lightweight is very important.

This will save you a lot of hustle along the way. Most of the lightweight toddler car seats for a 3-year-old are around 15 lbs.

Suitable for Toddler Weight and Height 

Make sure to find a car seat that is best suitable for both; your toddler’s height and weight:

  • The average weight for a 3-year-old is around 31 lb and by 4 years of age, they could be around 36 lb.
  • The average height for a 3-year-old is around 37.5″ and by 4 years of age, they could be around 40.3″.

Comfort and Durability

Many of us always tend to go with only manufacturers’ recommendations, and it is easy to forget, what is the actual comfort level of the car seat and how durable it is for upcoming travel.

Saying that always make sure to look at what are the features of the car seat, or booster that you are buying. Although our 3 year old traveler can make traveling much easier, it is important to check out the padding, harness system and what positions can the seat be adjusted to. 

When it comes to durability. It is obvious here. When you purchase the travel car seat for your 3 year old, the seat needs to be quite sturdy and well built.

This is important for both; the safety of your child, of course, and for how well it will perform in transit during all of the travel you will be doing.

Alternatives to Traveling with a Car Seat on Airplane for 3 Year Old Kids

What are the alternatives to traveling with a car seat on plane for 3 year old toddlers? On our travels, we have used the Newroutes Child Airplane Safety Travel harness, which has proven itself many times.

Please note that this CARES Child Safety Device is the only FAA-approved harness restraint for children weighing between 22 and 44 lbs (kids 1-year and older).

One of the positives of traveling with a harness is that it can fold into a 6″ stuff-sack and be put away into your backpack with ease. Weighing only 1 lbs does not add to your luggage weight allowance, and it is far easier to travel with than the car seat.

The only issue I have is that the harness does not allow for comfortable sleeping. The harness will keep your toddler upright at all times. 

Although we do love the harness now that she is older, I do prefer a car seat for 3 year olds.
