US Airways Dividend Miles (Pre-FlightFund Merger) - Any cheap mileage runs from CLE or BUF?

I need to do a cheap (hopefully) mileage run from CLE or BUF to make about 2500 miles for a challenge to keep CP until 2005--ideally to somplace warm with no Saturday night stay requirement, but realistically anywhere that would get this done for not too much money. Ideas?

P.S. Does anyone know if premium cabin class of service bonus miles count towards a challenge? (i.e., is it "preferred qualifying miles" that count, or just "actual" flight miles?)

IAH $118 no min stay! Act QUICK! E-mail me if you book one, I need to book one soon...
