I've only traveled before with car seats that we've actually used on the plane. If we're bringing a booster seat with a back on it (which I know we can't use on the plane), do I have to pay to check it in & pay for it as luggage? I know I could bring my son's toddler seat & either have him sit on it on the plane or gate check it but it is much heavier so I would prefer to just bring the booster. But of course I don't really want to pay $25 to check it in.
Thanks!
Thanks!
