I'm trying to read the wiki to get better understanding. I found this in the wiki section.

The only awards that do not break at HKG are intra-Asia or North American ones. For instance, Australia-Europe/Middle East/Asia outside of HKG will be two awards (breaking at HKG). The AS website can be misleading about this.

Does that mean I could use HKG as a stopover on DFW-SYD? (In order to take CX, I will probably have to do something like DFW-SEA-LAX to take CX flight).
