This is a great article with an overview of various car seats and other tools to make traveling by plane easier.
I wanted to share in case it could be helpful for travel planning.
I was a volunteer CPST (Child Passenger Safety Technician) for over a decade before “retiring” my certification, but I still pay attention to updates and recommendations. The Car Seat Blog site has been around a long time and is a well respected source of information in the child passenger safety field.
