Thread: Need Brazil Visa as a transit passenger-only if non-rev? What about dependents?

Hope someone can answer this question- I'm taking the family to S. Africa, flying into JNB.
Most routes direct from the US & via Europe are over-sold but hard to tell on Zed site.
GRU is pretty open, but from what I'm reading we would need visas?
Is this true? Even for transit-only?
Any help is appreciated!

This trip came up fast, so we don't have time to hop down to LAX to get visas.
And if anyone has any other routing recommends, please suggest away.

Travel begins at SEA-TAC, onward to either ATL (then non-stop to JNB ) or EWR on to various possible transfers, then JNB.
I've looked at LHR, FRA, CDG & ORY, AMS and even TLV or NBO!
Obviously looking to transfer to KLM or Delta if we can't get on SAA either.
Any ideas?
