what programs can convert US Airways miles to points?

[disneyberry]

hi guys, i'm starting to get antsy about US Airways... and they were my favorite airline and i've accrued thousands of miles with them. if they go bust, all those miles are gone i think.

so... i was thinking about converting my miles to points somewhere.
i would pour them into Hilton HHonors (working towards Disney PH Passes, heh), except US Airways doesn't participate w/ Hilton.

i saw some program called Milepoint.com for 2 cents every mile.

but can anyone help me out? are there other better programs for this purpose?
