Forget about access rules, just trying to find a lounge - anywhere in (domestic) Brazil - is more the challenge. Have low expectations and you might be pleasantly surprised
I am curious, at which airports can you have access to either the TAM or LAN lounges for Domestic flights? I will be touching base at these airports:
GRU
GIG
FOR
NAT
I think GRU and GIG should have at least a lounge for domestic?
Was not able to find this info anywhere not even on TAM's own website.
Cheers!
