Cheap flights!!!

SRR

I need two tickets to Texas on March 27th but all the prices I've found are $350+. I just recently found out that I have to be there, and air fare ain't cheap. Any ideas on cheap flights? I've searched Everywhere and I'm hoping you guys have some ideas I haven't tried.

**update**

Still searching, but if I can't find one then I just won't go. It was an important trip, but I can't afford to drop $600+ just to make it out there.
