I haven't flown CX in ages, but I used to fly LAX-HKG 2-3x per year from 2015-2017. I always flew Business as an upgrade from PEY. Looking back, I think I do notice some difference in the crews. HKG based were more attentive and less transactional.

At this day and age, what is the main benefit to CX of having overseas-based crews? I am pretty sure in the old days it was pretty common as CX hired FAs from 10 or 12 nations? I noticed on my flights that the Philippine, Thai and Singaporean crews were usually pursers and up, but none were junior crew. Does CX still hire foreign crews from around Asia?
