The hearts of BA Silvers reading that would skip a beat - in fact BAEC Silvers are OW Saphires

But no worries, that's sufficient status to get our friend into OW lounges, regardless of class of travel and carrier-imposed "lite" restrictions. But not into QR's: they like to be special, and have never quite captured the full spirit of alliance membership.

So for T1 I think that limits choice to BA and Qantas: opening hours might be the decider.
