Also the other point I was alluding to is nothing is stopping the local operators from getting together and forming some agreements with the airlines. Ie, not to do training in RPT arrival times, run an awareness program with locals to avoid peak times, where not to fly and so on. Why?, because if the locals can sort out some sort of sharing of the airspace and coordinate it's capacity it may ensure they don't end up with an enforced restrictive system that bludgeons GA out of the airspace when RPT is near. Its not always the sole responsibility of the powers that be to dictate what has to be done, which inevitably will not favor private or training flights.
