I think the scepticism comes from the history of people setting up operations with no experience in commercial private ops, tend to have a poor track record of being successful. (lets start a list - Gregg Air...Air Victoria to start)
I see that Blink are going to become an aircraft leasing company, who knows if they will make money, but understand this. Pilots and passengers want to know that the aircraft are being operated properly, not that the responsibility of safe operations can be purchased in the form of umbrella operations.
If my aircraft are run unsafely it is my responsibility. If Blinks aircraft run unsafely the guy from TAG goes to prison. Superior BA crew or not, I know which aircraft I would want to put my familly in. Also it makes stupid business sense to have the most key part of your operation not under your control.
Incidentally, most operators get weekly calls from people offering City Funding, just no-one wants it.
