Traveling with a 2 years old

Emily

Sorry this isn't a question about pregnancy. But I'm thinking someone else will have experience in traveling with a little one.

A month from now my little family will be flying to Louisiana to visit my in-laws and I'm starting to wonder how in he world to get his car seat down there. We'll be flying southwest and I'd prefer to check it like a piece of other luggage but how do you pack it or wrap it for protection?

Thanks everyone!
