Hi All.

I'm just about to book a DONE4 and thought there would probably be some sage advice to be gleaned from around these parts before I hit the "buy" button.

I am BAEC silver and will be putting all tier Points and miles into that account (unless someone advises me otherwise). I should hit gold somewhere around my GRU-LHR leg

Plan is as follows:
TPE(JL)NRT(CX)HKG(QF)MEL(QF)SYD(QF*)SCL(LA)EZE(LA) GRU(BA)LHR(BA*)HEL(BA)LHR(BA)MXP(BA)LHR(BA)HKG(CX) TPE

This all seems to work. The on-line booking tool looks OK and has given me a pricing, but I just wondered if anyone could offer any advice to allow me to:
- Save cost.
- increase miles and Tier Point revenue.
- improve my flying experience (never flown JAL. Prefer BA/CX. Happy with LA and QF. Prefer to avoid AA)

I have been through the stickys and done some searching and most advice seems to indicate booking through AA to save fuel penalties BUT I'm not going anywhere in the US. Would I be better off adding a TP run and going via LAX or similar for little (or no) extra cost?

My secretary has been pulling her hair out today with the OW booking engine, so I really didn't want to add more insult to injury and ask her to stay even later to look at other options

Thanks in advance for all the great advice.
