Safe standing is not currently permitted. I think what City might do is design an area in it which could be converted to safe-standing if legislation is changed.Safe standing gives additional seats in the same area than normal seating. Not sure what the ratio is. Basically it means more seats are squeezed into the same area. Meaning City can make more money, depending on what they price the safe standing seats at. Hence why I'm bulking at the £580 quoted in the email. There's no reason why City can't pitch the safe standing season tickets at £299, which is the same as the cheapest season tickets currently on offer.
For me the main issue is getting singers into the safe standing area, rather than people who just want to go in there because the safe standing seats could be cheaper, but won't bother singing. If this happens then the NS safe standing section will be nothing more than a safe standing South Stand level 1.
It is possible to have 2 standing to 1 seating with rail seats, and they do this for league games in Germany and that would increase the capacity. I'd be in favour if it was 2 for 1 otherwise we might as well just stand in the seats.
