Korean Air that flies to thrice weekly from Seoul to Sao Paulo via Los Angeles has launched a frequent flier partnership with GOL.
Korean Air Skypass members (and must apply for GOL Smiles members as well) are able to both earn and redeem miles for flights on GOL.
You can access Korean Air web page for GOL here.

It is good that most paid fares earn full 100% redeemable miles when credited to Skypass. I don’t think that the burning chart for GOL is as good.
I couldn’t find an English page from GOL Smiles for this partnership, although their frequent flier program members should be able to use their miles for flights on Korean Air.
