Having a private jet isn't cheap, and of course using any airport will incur some fees, but I don't think it's that much, since the last thing an airport wants to do is turn away the customers that keep it open. The thing with private jets is that they usually are not based in, or fly from, large international airports. Usually, they are hangared at small airports. Those airports simply wouldn't exist without those private jets, other private planes, and helicopters.
