That's the gravy. My advice would be read and read again. The very first thread in MileBuzz will give you a pretty good idea about the current offerrings as well as some historic prospective. Good luck and welcome to Flyertalk.
I would call the CCs the fuel in the rocket. Without them you are left slugging it out by taking connections instead of direct flights and wasting time on airplanes when you can be home earning 10-100xs those miles in a fraction of the time.
