Somewhat unrelated but still related - how do domestic connections work in Brazil? Seems like it shouldn't be too hard, as all the airlines sell them. Reason I ask if we may buy a roundtrip GRU-MAO-GRU then immediately connect GRU-GIG - seems like it would be a hell of a lot cheaper this way. TAM's fares have gone sort of bonkers. Would TAM check our bags through within b=Brazil even if on separate tickets? Apologies for the n00b question - we've never been to Brazil - so not sure how easy it is to make connections there or if its like India.
