I don't consider myself an authority on the subject but this is my appreciation from what I've read.
It is my understanding that eventually, Avianca Brazil will become a part of AviancaTaca, ergo the rebranding of OceanAir in 2010 (they use the brand for free) however, it may be a complex process to fully integrate it into AviancaTaca given that the owner of AV
Brasil is Synergy and AviancaTaca is Synergy + Kingston (Kriete Family from TACA).
The same thing happens with Avianca Ecuardor (Formerly VIP) whose owner is Synergy.
At the very end, German Efromovich's intention apparently is to fully integrate those airlines into Avianca and increase competition for LATAM for a big/strong latin american brand. His strategy seems to be paying off as far as I'm concerned.
I'm happy with this change. TA
is a great airline I've flown a few times, but that's the way the cookie crumbles in the airline world I guess...
