Costa Rica in $360s-$490s RT

This is Flight Finder Kristi:

Kristi is sad because she didn't book her flights to Liberia the last time they dropped in price, and then Kristi had to pay $1200 RT per flight instead of $400.

Don't be like Kristi. 

_{**True story, so if you are even entertaining the thought of visiting Costa Rica's tropical slothy paradise this winter, I encourage you to figure out your travel plans stat. Because I would bet my second born child that they won't be going any lower than this!!}
