Did you try pricing HKG - CEB on Cebu Pacific? In the Denver - Manila thread, somebody mentioned that you have to go landside to checkin on Cebu Pacific in HKG, so take that into consideration. edit: It was this thread, in the post from BangkokTraveler.

An hour connection is risky. Does it work better if you take the OZ flight out of LAX? What about the return?
