lets give it time i for one think brexit will be what the country needs in the long run but lets leave politics out of it and see where we are in 12 months. The fact FR flights are after the based aircraft are away seems like a very good way of keeping all partys happy and keeping the airport busy in what would normally be a quiet period and lets not forget there is faster growing demand for bucket and spade routes with the ever growing problems that has shut down routes like SSH/NBE and likely further reductions in BJV/AYT/DLM with the decline in Turkey. Those people will be looking to holiday still.
I also think if FR really wanted to trash the place they would of came in heavy handed 3 or so years ago , Just my two cents.
