According to a
Financial Times report, it seems Air Canada is seeing the benefits of new U.S. transit policy. AC is seeing a surge in non-Canadian origination traffic for flights to Brasil. The volume trebled between Jan.-Nov. 2004 compared to the same period a year earlier.
AC hopes to capitalise on BA's suspension of flights to CCS and BOG (flying AA through MIA or CO through IAH isn't a good option).
