When traveling with younger kids you will need to take all the essentials to ensure you can keep them happy and safe at your destination, and this often involves a car or road trip. Having a car seat with you when you fly can also be used in the plane cabin, so your little one can sit safe and secure. If this sounds like you and your family, then adding a car seat travel bag to your packing list is definitely a good thing. Not only does it make life easier when carrying the car seat, along with all your other luggage through the airport, it also keeps it safe and protected. Not least, if you find yourself in a position where you need to check the car seat into the hold.
