Count me as a recent convert. My wife and I travel 4-5 times per year. We finally got sick of flying coach with the masses and are determined to accumulate enough miles any way we can to earn more upgrades. This site has also taught me how to get cheap hotel rates too which has saved my over $2,000 in the last few months.
Of course, she thinks I've gone off the deep end when I talk about Mileage Runs, but that's why I love coming here!
I'm here to learn...and thank you all for your great dedication and insight.
