It has been my understanding that everything goes in the Cargo area. You can mark your box with anything you wish, but It still goes in one of those big metal containers that is stuffed in the cargo hold. Plus, I do mark my box according to IATA standards. If you don't these days, you could have problems shipping into Florida or California.
