Was looking at Air Canada's PDF timetable, and I was surprised to see Air Canada has begun code-sharing with VARIG via Sao Paulo to Santiago de Chile, Buenos Aires, Rio, Porto Alegre, Salvador de Bahia.

I'm wondering that why didn't Air Canada made a special news release about this? In the past, Air Canada has been released some news about their newest code-share routes, like the recent NRT-BKK.
