i agree with Tristar4ever, but i highly doubt they´d fly to GRU very soon. concentrating on star hubs at the beginning is certainly a wise decision, and so i suggest YYZ, Air Canada´s main hub, instead of Varig at Sao Paulo.
well, this is just a pure guess, but i could imagine bmi serving SFO, as Tristar already mentioned, as well as JFK or EWR from MAN (and not swapping this flight to LHR if they are granted rights to fly to the US from LHR).
what about LAX, BOS, MIA?
If only pure sweetness was offered, why's this bitter taste left in my mouth.
