Hey Robert, There are no flight plans included with regular hub assignments – only likely with special flight offerings, and then they’re clearly listed. Thus, you can use your favorite flight planning addon or software to generate FSX flight plans.  Once loaded into FSX, then the button on SPAACARS will automatically load the flight plan data you loaded into FSX directly into SPAACARS data fields. So for example: 

• Plan-G creates flight plan you want to fly for KTIX to KMIA with any SIDs and STARs you want to add.
• FSX loads the flight plan from Plan-G the usual way.
• SPAACARS flight-plan button loads the data from FSX into the correct SPAACARS data fields. 
• You add the flight number 2104 to SPAACARS IATA field.
• Start Log button becomes active and you can push it to start logging flight in SPAACARS
• When flight is done, if Econ Mode is set in SPAACARS then pirep uploads upon landing.
• If Econ Mode not set in SPAACARs then you push Stop Logging button and Send Log button to send PIREP.

 Let me know if you have further questions or problems.

Robert,

I do all of my flight planning with  skyvector.com/

It's great.  Gives you proper instrument departures and standard terminal arrivals.   AirNav  will give you all of your printable charts and procedures in PDF format.
