got curious and decided to compare, i know there are a lot of possible combinations with destinations, time of travel, time of purchase, capability of agent, etc... so take those into account but this was my experience. Note that i placed the call today, July 17, 2018.
Round trip business class, CX, YYZ-MNL, Dec 26, 2018-Jan10,2019- CAD$6,525 vs from Cathay Website - CAD$6,575 ($50 bucks wow)
Also note that the agent i spoke with did not seem knowledgeable enough to navigate their offerings and wanted me to specify which airline i wanted and that it is not necessarily the cheapest.. if we wanted we could check each airline to find out.. so this is probably a system bottle neck too...
