getting rid of default commercial traffic

[ciuwilliam]

I know this question has been asked before, but I'm noy sure where to find the answer. I recently downloaded project ai and added some flight packages to it like US air and American Air. How do i get rid of default commercial traffic like orbitz, landmark, etc and see more of ai traffic. I downloaded something from project ai that said it would remove default commerical traffic, but so far it hasn't worked. Can anyone give me some good advice. I am new at this.
