We got $500 rates from Boston leaving Feb 13 and coming back on the 20th on AA. We were able to save a good deal of money with 2 things:

* An overnight layover in Charlotte on the way down (fine with us, it means we get to MBJ in the morning on the 14th, less lines?). Plus I'd rather go through customs on the way back pretty much anywhere in the US than Logan Airport after a total fiasco last winter)
* Leaving on a Tuesday.

18 sleeps!
