Super deals on international travel (US to SE Asia)?

I know there are crazy insider things where you can fly super inexpensively – do you know of one?

I’ve been in the US for 12 years, and I’m on a mission to go back (solo trekking style) to my home area (SE Asia) for my 30th birthday for the month of November.
There’s Stuff I need to go reconcile.

I’m hoping to find a really great deal on the tickets. I’m on search alert w Kayak, but I know there are other things out there.

Thanks for yer help!
