Living in London, I would like a status match with BA. Problem is - they don't match. HOWEVER, and here is the interesting bit (and I hope this experiment works - I'll keep you all posted).

BD Diamond Club is matching one level lower than AF/KL FlyingBlue. If I understand it correctly, my FB Plat will become Diamond Gold.

THEN:
Some time ago, BD shut their routes from LHR to TLV. BA, very cheekily, is matching BD status for people flying on this route (ie ME) like for like (BD Gold to BAEC Gold).

Anyone try this before?
