I am United Premier and I believe I will be losing my status (and therefore * silver) soon. Are there any airlines that I can status match to for free or a way to keep the star alliance preferred?

I don't want to do a "buy a fast track deal" as the only airline I anticipate flying on over the next 5 months are either United or US Airways. Just wondering if there is something I can do besides having to earn Preferred status on US Airways and * alliance from scratch this year.
