Who tells the pilots where and when to turn?

Commercial pilots fly prescribed routes and general aviation pilots also fly prescribed routes as well as visual flight procedures (VFR) to and from Dallas Love Field as instructed by air traffic controllers. The FAA is responsible for managing our airspace and for ensuring the safe and expeditious flow of traffic. The City of Dallas is responsible for operating and maintaining airport facilities and for ensuring that runways (and taxiways and other facilities) are in good working conditions, meet FAA regulations and are available for use.
