Both "overhead airplane" style bags fit in and there is some space in between them where a computer bag can fit. And on top of them, we threw coats and a map, the video camera bag and some other stuff we wanted to get without opening up clothing bags.

So, bottom line, you may want to consider other more easily obtained bags. Just search for those sizes...
