Try CX online ticketing. i bought one before in June, it's only 1,400+ tax = 1,780. with 35kg luggage. and can change anytime without charge.
For my helper, i only get her air tix to Jatarta and not to her home town. I pay extra $500 to her as pocket money (actually for her 9hours bus to home town). She is very very happy. If buy a ticket to her home town, i need to have 3,280+tax .... no way!!
