Hi everyone. Can someone clear up for me the history of how these three companies are related to each other? Here's what I've been able to find:
-Varig helped set up Rio-Sul as its regional partner in 1976.
-Transbrasil helped set up Nordeste as its regional partner in 1976.
-Rio-Sul acquired Nordeste but kept it as a separate brand in 1995, at which point Nordeste also became a regional partner (?).
If the third part is true, why would Transbrasil let its own partner go?
Many thanks in advance.
