I don't believe that DC *G means anything to bmi anymore. I think they will be forced to retrench by *A to allow *G customers into their lounges on any fare basis, but refuse entry to their own, just like UA and the RCC.

Unless you need the upgrade vouchers, I'd go for SEN. You'll still have a silver card to open the lounge doors, which your SEN gets you into.

I've just made BD*G for another year, whilst resting my SEN miles for a year. Next year I'll be looking at keeping SEN and stuffing BD, unless there's a change in attitude at the airline.
