Argonaut, you'll probably have more success getting information here if you mention the desired class of service.

(I used cxleverage.com -- not .ca -- to get a r/t quote to TPE in Business for you. It came to US$3211.40. But that's not a special CXLeverage fare, according to the system. I think perhaps the cxleverage.com fares require origination in a US city, so I tried originating in SEA which yielded a fare of US$2153.90. Presumably cxleverage.ca could help you get a better fare, but I don't have access to its discounts -- have no cxleverage.ca account.)
