I saw one A346 at HKG a week ago. It was at a gate visible from the Wing (20 something) but I didn't notice it's destination. No doubt they are part of the EQV in the schedule. Given the loads on CX these days it is hard to see what route would ever need a 346 for capacity, so they might be positioned for cargo lift. Apparently the cargo business is keeping lots of CX flights afloat.
