So, after reading this post Most Underserved Airports and thinking about this again I have noticed that on a lot of airports that should get a lot of traffic there is like one plane, like the guy from this post said, one solution to that could be AI flights that fly around to keep realistic amounts of traffic so that for example some huge airports are not a ghost town. This I think would improve the game a lot and especially in single player when there is no one playing with you Ai, planes could be there. Tell me what you guys think of this.
EDIT I know a simular topic exists, so now I am trying to delete this one, ummm just gotta figure out how
