depends on whether you are restricted to weekends

I'm not seeing much out of DFW for 12/6-7 or 12/13-14

12/15 there's DFW-AUS-DFW-OKC-DFW for just under $200 a.i., nets 2000 EQM with the 500-mi min. per segment that's about to go away for non-elites.

hint: on AA.com try Multi-City, starting at 8am DFW-AUS, Morning dep. for AUS-OKC, Afternoon for OKC-DFW. You even get a couple of hours in OKC, enough for late lunch.
