Not sure about the booking history bit, you'll need to chat with the ticket office about that. However, you will not be able to book tickets for any game, so far in advance.
Well at the moment it's on sale to Supporters with a booking history at any time, which I admit is strangely early. But regardless my category far succeeds this.
Actually, forget that, I think the ticket office has done a cock up as it says:
Sale Dates
Currently: On sale to 2010/11 Season Card Holders*
Friday February 18: On sale to supporters who attended 5+ Home fixtures in the 2010/11 season*
Monday February 28: On sale to supporters who attended 3+ Home fixtures in the 2010/11 season*
Friday March 4: On sale to supporters with AVFC Booking History in the 2010/11 season*
...but if its currently on sale to season card holders why would it according to this be available to supporters with AVFC booking history this season...
Sorry folks, appears as if the website has made a mistake. Will ring ticket office tomorrow.
Friday March 11: On sale to all supporters with AVFC Booking History
