Pretty much all the "expensive" items cram into a Tamrac Expedition 8x pack, while the non-essential items will go in the duffel bag.  The camera bag when loaded up weighs about 45 pounds and (barely) fits in an overhead compartment.  I will likely use all of this at some point, though hopefully not the rain cover!

Out of all this gear, the one item that TSA usually stops me for is the monopod. I would have guessed the remote triggers.  Now where's my passport??
