Has the Federal Government, which funds construction and maintenance of the movement areas at Las Vegas airports and which provides airport ATC, decided that they want ANY fees, paid on any basis, to repay their costs? No they have not, so regardless of how other governments may structure fees to provide a return on their road and parking infrastructure investments, in relation to landing fees in Las Vegas this is just a discussion of how Clark County is collecting a return on an investment they didn’t make, contrary to the direction of those who made it.
Clark County can justifiably charge for FBO services outside of the movement area, provided by FBOs that they have built and run with local investment, but they cannot justify opportunistic charges for using airports funded by Federal taxpayers.
