My airports are in good shape ( all check out fine with AFCAD fault finder...parking spots are fine, etc.) but at KATL all the jets vanish after landing and going down the runway a bit. The prop planes don't do this. There's lots of available parking of the correct size. I'll probably see this at other airports too; some of them are very empty despite the fact that I have lots of flightplans for them.
This happens with my own flightplans and PAI flightplans.
