With TAM getting out of *A soon, i would like to know from the experts what would be my best bet for OW in south america? I am not much familiar with OW FFPrograms but I hear that LANPass is really bad. My home airport is POA but I use SaoPaulo-GRU very often. I fly 50k per year usually with *A carriers, normally economy.
Also, would any OW airline match my *G status?

Thanks a lot.
