I did this year's Seattle to Portland ride on a rental. I brought my own seat but not my Vision 40 wheels. I didn't really miss the wheels - I don't think it would have been worth the hassle.
One thing I did hit: I brought my saddle bag with tools, flat repair, etc. No problems on the way out, TSA in Portland on the way back took my CO2 cartridges, as apparently they are verboten. So, either bring a mini-pump or plan on donating a few CO2 cartridges in one or more airports...
