You usually hear "cleared via xxxxx direct" when requesting clearance. A controller will tell a pilot, "cleared to Teterborro via FAILS, Victor 522, Erie, Jamestown, direct..." for example. What that means is the pilot is first to fly to the FAILS intersection, then via a "victor airway" numbered 522 to the Erie VOR. Next he/she should procede to the Jamestown VOR and then direct to Teterborro. Keep in mind this is just an example of a real route from the Cleveland, OH area to Teterborro, NY.
Victor Airways are basically highways in the sky, as are Jet airways like the J20 and J68 that you mentioned. They sometimes connect two VOR's and sometimes strings of VOR's (navigational beacons) and where two of them intersect, you will find "intersections" which are really nothing more than points in space. Intersections are different from NDB's and VOR's in that they do not broadcast any signal, and really aren't tangible objects at all. GPS systems, FMC's and VOR crosschecks are some of the ways to fly to an intersection.
I hope this hasn't been too complicated, I'm no CFI so my teaching skills aren't too hot.
