Not at all. The carriers make sure the skids are greased for their flight
plans to seamlessly and automatically transfer from their host to the FAA
host. Unless someone wants to manually change a route on an air carrier
domestic flight plan, no human is even involved. It all is computed and
sent to the appropriate station and the FAA in a timely manner.


Flight data processing is done exactly the same for the carriers as any
other operator.
