The worst part about traveling with kids, especially when flying, is carrying all their stuff. Even if you take the bare minimum of entertainment and snacks, you’re stills stuck with all the necessities, “what ifs” and worst of all: car seats.
Because it’s not safe to rent a car seat, and it’s not advised to check a car seat (even gateside) for risk of it getting lost or damaged, and all kids require some form of safety device getting to and from the airport if riding in a car, that leaves most parents schlepping car seats on and off the airplane. And often multiple seats if there are multiple kids involved!
