CX actually charges the highest on this route. The cheapest on this route is usually EG (Japan Asia), but they only offer one flight a day. TG have 2 flights daily, and they charge around HK$1400 (I took TG on that route last year, not a bad flight). When you go up the list, CI, BR, KA are around HK$1500 - 1900. CX should be around HK$2000. And I agree with everyone that it is definitely cheaper to get the tickets in HK.
