Since the continent is huge and you didnt share with us as to where you would like to go, i will assume Sao Paulo, Buenos Aires and Santiago will be in the mix as well. In addition to CM, TA, LR, JJ and AV, you also can fly TK on GRU-GIG and AC EZE-SCL. Be forewarned that aeroplan.com can be buggy with intra-South America awards and that if you want Machu Picchu in the mix, CUZ must be your POT since its only served from LIM with TA.
