Bushy nails it with his comment about the difficulty of selling all instead of individual seats. I think that the trend over the last few years, of enforcing an essentially draconian requirement, has seen the demise of this section of the industry. God, charter ops used to be the life-bloood of the north and I cannot recall one single incident where pax safety was threatened because a 'charter operator' sold seats individually. And my recollection goes back to the earlies when the old tarmac opposite the 36 THOLD in Darwin was chokkas with aircraft belonging to 'charter operators'. If anyone can enlighten me to the contrary, I'd be interested.
Bloody sad.
