I'm not sure how to respond to this, your answers lack detail or arguments to respond to. What difference does chartered Vs private make for emissions? It's the same types of jets, just changes who actually owns them. It also makes no difference to the entire tax subsidized argument either.
As to "how many times", as I said above I haven't found a clear answer, but different sources claim between 10x and ~40x, even assuming the very low end of 10x, that's a big difference. I assume the per passenger emission is hard to measure since the number of passengers on a plane make a big difference.
Either way, I believe I made my points in detail several times now, and as I said your responses don't really raise points or include much detail to further things, so I'm going to leave it here.
