True, they are not going to be operating EZE
with SWISS aircraft, however they will codeshare with someone, although the other airline has not been named yet. I believe TAM would be a good candidate...they already code-share with AA
(also a oneworld member) on some US flights. In fact, if TAM were to join oneworld, it would be a good complement to LAN Chile in South America. Will we see TAM joining oneworld sometime soon? Now that the Varig/TAM merger is pretty much off (at least temporarily) it might be a possibility.
By not operating EZE
can operate the GRU
route with one aircraft. For now, it seems that GRU
will get 5 x week service, even when all 9 of the new A340's have been delivered.
