The Bournemouth picture is a very common one. When an airport is quiet, GA is welcomed with open arms. The moment an airport gets even one scheduled flight operating it sees itself as another Heathrow and GA is beneath its dignity.
Bournemouth has gone down the path of attracting scheduled and large jet aircraft, so GA will be discouraged and have to find a new home. I don't like it much but we are stuck with it.
Bye bye Bournemouth.
