I don't get it? If you want a sky full of AI planes, fly offline. If you are flying VATSIM, turn AI traffic off completely, otherwise you just have planes flying their own agenda's, getting in the way of VATSIM controlled airspace. It will just create total confusion for you....

You don't have AI traffic on multiplayer (AFAIK). Every plane is a RW user. What the packages add are liveries for real world and virtual airlines so that you see those other user planes as they are supposed to be seen, not as a generic paint. If you install FSInn, it builds a database of plane liveries based on what planes you have installed yourself. I can't speak for anything else as I've only used FSInn but assume they all work similarly. Just install FSInn and see for yourself how it works.
