Is it possible to fly the same flight more than one time?  I am interested in flying the exact route multiple times over several months.  Can flights in history be "reloaded" back to the aircraft to fly the same route multiple times?

Not from the history. You can set up way point missions to repeat a route multiple times.

LITCHI is the way, you have saved missions that you can recall and repeat as much as you like

Hi Sky2PIC, rent is absolutely right, please create the mission in Waypoint then you can repeat a route multiple times.

Thanks for the responses!
