A little late in posting, but I managed to get a hold of a "limited edition" Sunderland International Airshow 2013 ticket earlier this week.
See attachment for a Concessionary Single purchased on 22074, a vehicle which was being utilised on airshow shuttles on 27/07/13.
I unfortunately didn't get one - had my Nexus CAT ticket that I used on the shuttle instead.
