Thank you guys for the advices. I'll try to contact CX in Indonesia, but will also consider going thru CMB.
I can buy a RT BRU-CMB instead of BRU-DPS, and use my first two segments for CMB-HKG-DPS;
The purpose of this RTW is making it to AA EXP this year, need approx. 50K miles to reach it, and this in two trips, first from DPS back to BRU, and a second trip to CUN. So i can use some advice to maximise my itineray. I need a combination of long "real" first class flights and the best connection times, to minimize the days of travel, need to stay 8 OR 9 nights in Cancun.
This is my itinerary so far:
cmb-hkg-dps-hkg-SYD-lhr-BRU-hel-BRU-lhr-mex-dfw-jfk-yvr-dfw-CUN-jfk-hkg-cmb
The cities in capital are our planned stops.
