I've been using MSFS since version 4, but I've never really added much on to
it. Now that I've bought 2004 I'd like to add authentic AI traffic to my
default location (Saskatoon, Saskatchewan).

Does anyone know the best way to do this? As far as I can tell I need to
have the correct types of AI planes, in the correct liveries (Air Canada,
WestJet, etc.), and then somehow make them follow a realistic schedule.

Any help would be appreciated.

Cheers!

Jeff
