US Airways Dividend Miles (Pre-FlightFund Merger) - US Airways mileage run from RDU?

I'm a GP with 42,000 Preferred Miles for the year, and I have the following flights coming up:

RDU-CLT-MCO-CLT-RDU = 2,000 miles
RDU-PHL-BGM-PHL-RDU = 2,000 miles
RDU-CLT-ORD-PIT-RDU = ~2,200 miles

I don't think that there are any promos/bonuses for those flights. So, by my calcs I will end up about 1,800 miles short of GP status for next year. Any suggestions on a suitable mileage run from RDU? Is there another way to get about 2,000 Preferred Miles?

Thanks

I got an RDU-CLT-TPA round trip to price out at $118.50. RDU-CLT-BWI was slightly more.

A 14 day advance purchase RDU-CLT-JAX, base fare $110.00. No overnight stay requirement.
Down and back in the same day; fare basis VRA14QN1.

JAX-CLT-RDU is our favorite mileage/segment run. Less than 6 hours round trip and no worries about missing your return as the same equipment turns around. Even Mrs. AtlanticBeach understands this Mileage Run and will do it without being in her customary seat (2C).
