Viable Model?
Skyman - I have no way of knowing whether this is a viable model or not, as I am not on the inside. As I have said before, being prepared to lose flights does not strike me as a sensible move, but one can only assume that it costs more than you earn OR the move isn't sensible.
As for a future without IT flights and whether that is viable - that entirely depends on whether there is enough profit in the non-passenger sector. You would hope someone has done their sums and figured out the answer is 'yes'.
In all honesty; none of us know what is going on. But I am clear that the future has to be different to the past and DTVA has to be a differentiated or niche product to survive and prosper. It would have been nice to think we could have achieved this difference and niche WITH charter flights however....
