Nice post. Not everyone is adept at using the search feature. How do you know the OP didn't already try that?

To the OP: There are others here that are more experienced than I, but I think you'll find it hard (impossible) to consolidate your miles without taking a heavy hit.

Do you have time to earn enough miles through other means? Credit card sign-up bonuses, I-Dine (or whatever they call it now), cc purchases, etc.
I don't know about the other programs but with AA you can get reduced fare tickets with 15K miles. Maybe that's an option for you? Only 8K to go.

Good luck.
