I guess I was sort of thinking aloud...
There is a market for fractional shares. Its just not as huge as first imagined. The same can be said for the VLJ market, for example. So many manufacturers jumped in when the idea first presented itself.. no way they could all survive.
So, I think now we are seeing a market correction with supply more closely aligning itself with demand. The fractional model is larely suffering from the economy's affect on the used airplane market.
In terms of charter, small operations are finding it impossible to survive. Other larger players are outpricing their home-based competitors with large fleets and point-to-point pricing... basically operating like a fractional company with floating fleets spread throughout the country, but with different pricing structure for the customer. A largely fractured charter industry is being forced to consilidate.
