This really isn't very exciting. There are numerous ways to buy UA points for less than .72 cents/mile now. I can think of a REALLY EASY way to buy them for .52 cents/mile, and a slightly more complicated way to buy them for under .2 cents/mile. All these methods are completely public, on FT and (definitely) on the blogs.

If this post were talking about a way to buy AA miles for .72 cents/mile then I'd be more interested.
