Any FTer who "gets it" can buy an unlimited number of US miles for about 1.05 cents each using this promo:

Same excellent award availability as CO miles (but need to call as US website is useless) and an excellent Star Alliance award chart. You can use Continental.com to find what is available then call US to book it. 99.99% of the time, US will have access to the same Star Alliance seats that Continental does.

In almost all cases, the US Airways offer is a much better deal.
Lower cost per mile and almost always less miles required with more ailrine choices and better routing options to book.
