Car seat bag for traveling?

Anyone have a recommendation for a car seat bag for traveling? Last time we flew somewhere, my son’s car seat was damaged in the cargo hold, really want to avoid that

? We used the car seat on the plane, or is your child young enough to sit on your lap? Not sure if “Fragile: handle with care” labels would help.

It really is best for your child to use the carseat on the plane, checking a car seat can really damage them in ways you shouldnt use them at all after.
