Just wanted to pass on my thanks as well. As a newbie, this is a great introductory. I've been lurking for awhile, and am quickly learning a wealth of tips about using FF miles to the maximum benefit.
I'll continue reading to learn more about mileage strategies and perhaps post again when I have a more defined goal, but just wanted to say how appreciative I am to have information like this rather than having everyone assume that Newbies should come in knowing all the information already! Thanks again!
