What I'm really hoping to clarify here - as the Diamond Club agent I got on the phone was totally useless - is whether W on SQ will qualify for any points in Diamond Club. I can certainly make use of just 15,000 in KrisFlyer (one-way within Asia for example), so I'm happy to join a third scheme rather than lose the points altogether.
By-the-way: W on BMI longhaul accrues at 100% she told me.
I don't want to advertise my own thread here that much

but have a look
here and you will find links to all major *Alliance airlines and which class earns how many points in each FF program. For BMI use
this link and you will see that SQ in W class earns 100% miles. Hope that helps...
