I am planning a trip to Asia and Sydney and Brisbane for Feb/March 2005.

I will be traveling in J

My expected routing woulde be LAX/HKG/SIN (WITH POSSIBLE HKG/TPE/HKG IN THERE ALSO- ALL ON CX

THEN SIN/BKK ON CX

THEN BKK/SYD ON QF( STOP OFF IN SYD- CAN i DO THIS FOR 2 DAYS OR DO I ONLY HAVE 24 HOURS??
THEN SYD/BNE ON QF
THEN BNE/SYD/LAX)NO STOP OFF IN SYD-ONLY ROUTING THIS WAY TO GET NEW SLEEPER SEATS IN J AS BNE/LAX NON STOP NOT FITTED AT THIS TIME.

Questions:

Who do I call to get this ticketed? Can I call AA? or do I have to call CX?

Is adding in HKG/TPE/HKG possible?

Can I go through SYD twice (stopping off only once) or does this break some rules?

Is this trip based on mileage alone. Anyone know approx cost? I suspect that it is a lot less than the $8k approx for regular booking.

Any assistance would be appreciated

Tks
