At the prices quoted for travel and tickets, and based on the complications of purchase, the probable need for accommodation, and just the general feck about, the demographic of this will almost entirely be single fans aged 18-30 and older men, with nothing else to spend their money on.
I suspect there will be very few families, single ladies or older couples. I also don't believe for one moment there will be huge take up from Supporters Clubs as they have always prospered on cheap hassle free easy travel with tickets provided. In effect, you got your arse wiped for you! Many SC members, when faced with sorting this for themselves, will just say "Now where did I put the remote control?"
This really is hard core, and based on that alone I believe this probably won't sell out even with members getting their chance, as by then flights will have increased yet again.
