Moms! If you plan to fly anytime in the first few months with your baby, save your carseat box! A carseat is checked for free, but in the bottom of a plane it could take quite a beating! I packed mine in its original box, padded by blankets, and even added some diapers and baby clothes, our shampoo and other things. Its like an extra checked bag for free! I packed my carseat at the airport on the sidewalk outside without an issue. :) (Don't forget to reinforce the sides and corners with tape! I used clear packing tape and it survived 2 flights, one with a layover!)
