I have to travel from BNE to several US points next month. These are (in this order) SFO/SJC, DFW, ORD. I want to travel in J/D and will be personally paying the difference between the economy class fare my employer will pay and whatever J/D fare I decide upon.

Originally I was planning a DCIR22 going BNE-LAX-DFW-ORD-YVR-HKG-BNE. Then I found I also need to hit SFO or SJC and that won't fit into 22,000 miles and still allow me to to hit DFW and ORD and use CX over the north Pacific. I could go ORD-NRT-BNE, but that is less attractive to me.

So I am thinking that the difference in price from DCIR22 to DONE4 is not that great, and I can definately requalify QF WP status in this one trip.

An additional consideration is to include as many QF flight numbers as I can (codeshares ok), since our corporate discount on the OneWorld fares is greater when more miles are flown on QF flight numbers. I have to weigh this up with maximising QF Status Credits (more important to me than miles) and the fact the difference from a BNE-LAX-SJC-DFW-ORD-LAX-BNE economy fare (porbably B class) will be coming from me.

If I do go for a DONE4, then I will also spend a day in FRA (business). But I don't want to spend too many extra days getting home from ORD, so things like adding an extra LHR-DXB-LHR are not going to fly for this trip. I will have some weekends in the USA to spend flying if that helps the goal. But don't want to add to the travel days with touring over Europe and Asia.

I would also like to maximise my chances of flights with the new QF Skybeds (so BNE-LAX, FRA-SIN, SIN-SYD on QF6, SIN-BNE, HKG-BNE etc are out).

So far I am looking at this routing (1300 SC's, 85,000 QFF points, 36,800 miles flown, 15 sectors):

BNE-SYD-LAX-SFO-DFW-ANC-ORD-BOS-SFO-LHR-FRA-LHR-SIN-MEL-SYD-BNE

Another option is:

BNE-SYD-LAX-SFO-DFW-ANC-ORD-LAX-JFK-LHR-FRA-LHR-SIN-MEL-SYD-BNE

This is less FF points and less SC's, but I can do ORD-LAX-JFK on QF flight numbers which will bring the cost down.

The LHR-SIN-MEL-SYD will all be the same QF10 services, but on separate coupons to maximse SC's. Another thought was to take the daytime departure QF32 from LHR to SIN, then CX up to HKG and QF128 overnight HKG-SYD, allowing me to spend some of the day/evening in the CX Wing lounge.

Any other suggestions of options to consider? How to best use the additonal 5 sectors without adding to the days to get from ORD back to BNE. I don't mind overnight flights if they are earning me lots of SC's (like DFW-ANC-ORD).
