Virgin Clubhouse access has been there since day 1:

Only works at true Virgin Clubhouses, not the shared facilities.
Only the people holding black coloured cards on the account can access, so no guests and no platinum supplementaries
Only applies for UK issues Centurions, beginning 3742 8

The benefit booklets are a joke, i have never received an updated one in 5 years; I got one when I first joined and that is it. Thank goodness for FT!

Thanks,
Richard
