> how to make airspace more dense without compromising safety.
My suggestion would be to make things as repeatable and consistent as possible. This would mean forcing some airports to change their practices to be consistent with everyone else, and forcing physical layout changes and construction. Unfortunately an app can't do that =( ... and the benefits are on the other side of a paradigm shift, so it's hard to make it happen naturally.
>> more dense
Large, high passenger capacity airliners have gone out of style but that would have been the best way to get passenger density up.
