I'm in the same boat/city and I think that right now the best route to try is AUS-SAN for about $100.00 AUS is located on the way to Austin so if you take I- 10 west and connect to SH-71 W you will go right past AUS.
I have contemplated taking a mileage run AUS-IAH-SAN-IAH-RDU/TPA/MCO/??? and back. That way you get the full transcon and a cheap seat with the double miles...
My 2c hope it helps.
