Dean...I"m fairly sure that you will be able to sell this at DTD when they open.
Tighty wil be taking alternates from 1.30 and if you approach someone asking then you may be able to get cash on the spot. All you would have to do then is liaise with Leigh and the cash desk BEFORE they put up the seat assignments to get the names swapped over.
Otherwise, TBH...you"ll be SOL.
Paulie.
