LGW Vulture is correct. The business model is flawed. The biggest cost of operating a new(ish) aircraft is interest and depreciation and the low offered rates needed to generate interest for clients to actually go in a toy aeroplane does not pay for the aquisition costs.
The only way a VLJ might possibly work is if the operation was tacked on to an existing operation so the overhead is not solely borne by the VLJ operation. Until then the business model is flawed and doomed to fail
