High ST sales… all good news?

I remember last season there being a fair amount of chatter about the number of empty seats at home games, some of which was attributed to ST holders not showing up.

Genuine question… Is there a scheme that allows ST holders to transfer their tickets to others?

I’m just wondering whether high ST sales is a good thing across the board… Both based on the risk of empty seats, and also the fact that it necessarily means that such a high number of seats were fairly heavily discounted.

Passing it over to those who know more about these things than I!
