I'm planning on adding some America West, American Airlines, and United Airlines traffic to my local international airport, KDSM. I also want to add realistic traffic to KDFW and KIAH (the default versions of each). I'm going to download the corresponding AI Aardvark planes and schemes, as well as the correct AFCAD files for each, but what else do I need to do? I'm sure that I have to download some flight plans as well, right? The problem is, I don't know how to incorporate the aircraft into my sim. Is there any tutorial out there that could help me, or could anyone explain? Thanks a lot in advance :)

The simplest thing to do is got to Project AI and download the auto installer and the packages for the airlines that you mentioned. You will be up and running in about 10 minutes!Good Luck.....

Awesome, I'm getting the installer right now. Thanks!

If you are getting the Aardvark aircraft, you might want to check out this place too http://www.mostrealisticai.com/main.phpIts realistic flightplans - but downside is you have to put in the aircraft manually. PAI though comes with their own (less FPS friendly) aircraft.

Just spend the money and buy Ultimate Traffic, well worth it.
