Not in the least. bmi gives 50% miles on many cheaper fares and 25% on the web-only specials. All those fares would get 100% on LH's M&M card, and that's with 1000 minimum miles (so clearly UA is definitely not for BD flights).
However, if you will be on economy fares mostly, then the bmi card's for you. BD*S/G will get more OpUps than other *S/Gs, needless to say.
Use your Cathay card at
www.ukstatus.co.uk for a match to either LH or BD *Silver - that gets you (more than)half way there.
Your choice is then simple - LH is much more rewarding, but it's much harder to get *G on LH. So only join M&M, instead of BD DC, if you intend a lot of C flying.
Your trips to the far east and LAX will get you BD*G even in Y, but not necessarily so with LH, as you'll only need another 38k on top of your newly comped BD*S.
