I have flown a fair amount (but not like you all!), and been a lurker on this forum a bit too. I'm particularily intrigued by you "mileage runners". And I don't usually fly America, but my friend convinced me to sign up for a few credit card deals, so that's why I was looking back at my old AA miles.
But I signed up for the AA and United credit cards, so I should have a bunch of miles on the way!
Thanks for the warm welcome...
