As I'm about to embark on my first trip of the year I need to decide where to bank my *A miles.

I have both TG*G and BD*G. My BD*G is comped while my TG*G is earned. I am in the 1st year of a new 2 year period of being TG*G. I also have a comped LH*S but that seems irrelevant.

I'll be based in DEL and flying mostly within Asia/ANZ and mostly on TG metal. I will also be flying to the US once or twice and plan to do that on AA/OW.

All of my flights are in Y, mostly on cheaper tickets. I sometimes find myself on TG V class tickets which don't even earn miles on TG. Each time I did a standby upgrade on TG it was on V class tickets so no points.

If I bank this year with Thai I can extend my gold status by another 2 years beyond 2011. I also earn another Gold Upgrade.

What are my benefits with regards to re-qualifying with BD? Is there any value to doing so in order to stage myself to have LH*G assuming they merge DC into M&M?

Suggestions? Other options I'm not looking at?
