I certainly agree nobody likes the drop off - I don't but have paid it a few times.
The airport did run with minimal services and survived whilst doing so. The difference now is that MAG take the profits from the industrial estate directly into their coffers, thus preventing that contributing to bournemouth's profits and they also expect pay back of the money invested in the terminal etcetera
So- do they cut their losses or continue to subsidise the aviation side?
My understanding is ( and admittedly it's at least second hand) that the airport has been told to sink or swim on it's own and it now has a very large financial black hole to fill.
