When I travel for business I don't check bags, I bring on board a "legal" rollaboard and, as my personal item, my computer bag.

When I travel for leisure, I usually take a Lowepro Minitrekker backpack (you can see one here: http://www.mobileplanet.com/product.asp?code=131904, along with my Tumi computer bag with wheels http://www.tumi.com/business_laptop_...?modelid=57431.

I've always considered that my one item plus small personal item, and wind up checking a garment bag or rollaboard for my clothes. In a recent thread on FT, however, I read that both the FAA and TSA will allow a camera bag IN ADDITION to the "one carryon and one personal item." Is this correct, or did I misunderstand the poster? I would love to be able to bring on board my rollaboard, my smaller Tumi laptop case (not the wheeled one above) and my Minitrekker backpack.

I'm not interested in a debate on carryon versus checking. I'm only interested in whether FAA and TSA rules will permit "one plus one plus camera bag," and, if so, whether the airlines permit it as well.
