I point o my own example up thread on denied Lounge access as I was accruing to TG (Silver), despite being NZ Elite...? Other *A carriers have no issue with this. Indeed AirNZ used to allow it until 2014-ish when they changed the Airpoints T&C.

As nzkarit pointed out, there is no *A additional carry-on entitlement across the alliance based on status - so (devil's advocate question) why would a LH*G pax, on a SQ ticketed flight, under an SQ codeshare (NZ metal), get this non-*A benefit?

I do think this should be clarified and the text improved.
