I need to do a business trip in CW to BNE first week in June 1st-5th and spotted on ITA the routing it suggested MAD-LHR-HKG-BNE BNE-SIN-LHR-MAD (£2.8k)would net me 740 points including the positioning flights but I need 830 to reach Gold before my TP end of year which is the 8 June so very close.

Does anyone have any ideas on any alternates that would work I've looked at OSL, AMS, DUB, BER which are attractive especially on the QF/Emirates code share which hopefully still nets TP's. However price is also important as I need to justify any weird routing with a price benefit over ~£3k direct from LHR. If anyone has some good options I'd appreciate them as long as they are flat bed for the long haul legs. I couldn't work out how to do the complex multi-hops on ITA. So any hints on how to do that would be appreciated I thought I'd understood the various guides but it is a behemoth to manoeuvre round when you only use it occasionally.

Thanks in advance.
