What the club might do, as other Premier League clubs have already done, is to either abolish age / senior concessionary ticket prices altogether, or to limit concessionary price admission to particular areas of the stadium - in West Ham's case, to the less popular and less accessible areas.
Can't imagine them doing that here if we're relegated - but who knows and what effect would that have on season ticket renewals? - but if we do manage to stay up I can very much see that happening.
But anyway, I've already decided not to renew without there being drastic boardroom / management changes, none of which will happen
