My limited experience flying the HKG route is that there are a higher proportion of non-HK people on BA compared to CX. Additionally the Chinese on these flights are more likely to be HK people rather than other asians since BA doesn’t have connecting traffic from China like CX does. HK people generally speak English so there’s not such a demand for Cantonese speaking crew.
erm. no. there are bus-loads of chinese from southern china who is on the back of the a-bus. cuz canlhr flies on silly hours.
on the good side BA may get rid of these low-yielding pax.
