I know the resale window was open as I tried to BUY tickets during it,
I think it was either January or February and the whole ticket site crashed, in the end sales of tickets were suspended but they were buying tickets back if you no longer wanted them.
I can’t find the specific reference to June just now but think it was in 1 of my confirmation e mails from the open session recently
This was in one though ……………
Ticket resale
If you are no longer able to use any Olympic Games or Paralympic Games tickets you have been allocated, you will have the opportunity to resell your tickets at face value through the official London 2012 ticket resale programme in 2012. This will be the only authorised way to sell any tickets you are unable to use or buy tickets from people offering tickets for resale.
Tickets are strictly non-transferable and must not be sold or advertised for sale on the internet, in newspapers or anywhere else other than via the official London 2012 ticket resale programme. Please read Terms and conditions of ticket purchase at http://www.tickets.london2012.com/purchaseterms.html for full details about the transfer, resale and use of tickets.
