Having a "close working relationship" isn't really the point, though. And I wasn't really referring to any current clients a carrier already has- I mean hey, if ya got the contract, all you CAN do is your best.
In the USA, there are a whole bunch of companies that I was hoping to find out about. Because the charter market is so huge there, if shippers have ANY sort of lead time, using a service that essentially shops around the best price for you will save you money every time.
Big companies like all the auto makers etc. use this alot, because they constantly have a need for oddball charters, and may not know the name of XYZcargo charters that flies from "Podunk international".
Thanks anyway, and FYI check these sites out:

www.cargosphere.com (mainly ground, but some air)
