From the club article posted this evening:
The current sales figure means the Sky Blues already have their highest number of Season Tickets since 10 years ago, when they had 8,235 in the 2011-12 campaign. Following the move to the Ricoh Arena, from 2005 to 2011 Season Ticket sales were regularly between 9,500 and 10,000 and the Sky Blues will be hoping for similar numbers once social distancing allows capacity to reach those levels.
This goes to show that even when we averaged 20k attendances in the early days at the Ricoh, we still only had a core ST base of circa 10k. To regularly fill the Ricoh we would need maybe 18-20k ST holders?... which is a tough ask
