Just a little factoid, there is an 18% FET on chartered flights, so a typical $20,000+ round trip from TEB to MIA incorporates about $1000 for Uncle Sam, include the roughly $2.00 on 1200 gallons of JetA for the r/t= $2400.

So yeah, there are user fees, they are called taxes in this case, but the net for the gov't is $3400 for 1 airplane going to MIA and back to TEB.
