Regarding the above comment:

"I current use American Express Memebership Rewards and you can transfer to most airlines, but not necessarily all. I assume that the points from the CC go into the Starwood program, and from there you can transfer them to most airlines."

It's actually not that simple and MR is NOT Starpoints, which allows 20k pts to 25k miles!
