They're teasing you, buddy.
There have been many discussions about a global map for DCS but that ain't gonna happen.
There are many technical complications like who's gonna detail the whole world, lower performance, a big modification to the graphics engine... etc
And at the end of the day, DCS is a military sim and it's better off with specific conflict maps like all the other military sims in the past.
If you want ferry flight, you might want to navigate in P3D and when you land either in Nevada or Caucasus, close the sim and start DCS in those maps
