Just so everyone knows,my original Ultimate Traffic didn't come with American Airlines. I couldn't figure out how to install the A^A update,so I installed Project AI
's - works great! The planes actually look better than UT's . I also installed National (Las Vegas based one). Since they are out of business , UT doesn't have them,but Project AI
did. As long as you don't install 2 of the same airlines it works fine.
