US Airways Dividend Miles (Pre-FlightFund Merger) - Any way to find the cheapest airfares from point A to anywhere?

I'm looking for someplace to go on the cheap for Thanksgiving & returning the next day--hoping to take advantage of the least expensive fares over the holiday weekend. US Airways say there are fares from $118 R/T, but from here, I can't seem to find them. Is there any fare engine out there that will allow me to say that I want to fly out of ERI and give the the cities I can go to for the least amount of $$?

P.S. It would be nice to see a special Thanksgiving quick trip mileage award, too. If they're willing to give tickets away for travel on Thanksgiving and returning later that day or the next, then why not offer a 20K mileage award that does the same thing? As it is, for a freebie, I'd need to spend the premium miles since Thursday-Friday does not a Saturday night stay have. :(

Travelocity Dream Maps (http://dps1.travelocity.com/dreamMap.ctl?Service=TRAVELOCITY) works for fares out of a city.

A Quick search finds a bunch of cities with cheap(er) Holiday fares:

RDU (109+)
TPA
FLL
RSW
MSY
ORF
PHL
ORD
NYC

Enjoy!
