CX RTW's
 

Does anyone know what rtw fares CX has in effect for travel originating in U.S. or Canada.

The ones I could find are the UA/CX fare and the oneworld fares.

Are there any others?

from "biz traveller aisa pac edition",
there are ex-hkg fares for cx/twa, cx/ac, cx/dl, cx/kml/nw. i guess ex-NA also exist, call these partners to find out the fares (fares about the same for all these, some 15% below cx/ua fare, with cx/ac lowest)

There is a CX/NW/KL fare.

If you can bear flying business class with KLM/NW for one segment(they don't offer first class), then the CX/NW/KL first class fare is a good deal.

Sample Itinerary:
YVR-JFK CX First (A class waitlist, confirm D)
JFK-AMS KL Business Class
AMS-HKG CX First
HKG-YVR CX First

Only for about CAD 5900 (better deal than round trip fare between YVR-HKG of CAD 6600 from a Chinatown consolidator, or CAD 8186 direct from CX)
