I agree that Canada is weak/non-existent, and North Asia is pretty weak (regional flights in Korea, Japan and China), but south Asia is okay, IMHO.

In addition to the CX hub in HKG, CX also operates TPE-NRT, TPE-SEL, BKK-SIN, and SIN-CGK. Also, QF operates a "mini-hub" in SIN with intra-Asia flights to CGK, DPS, HGK and BKK. Finally, AY operates the BKK-SIN route.

If one wants to go from anywhere south of HKG to North Asia, however, it won't be a direct oneworld flight.
