The routes are referred to as J-routes and designated by a number for easy identification (e.g., J110). With respect to position reporting, reporting points are designated for jet route systems. Flights using jet routes will report over these points unless other-wise advised by ATC (air traffic control). Also referred to as high-level airways.
