In the main fsx menu there us a airlines.cfg file. Just type them into that and it works

That's very interesting. I tried that with mine and it didn't work. By not working I mean that the ATC doesn't use the ailine call sign. It lists it but no ATC spoken call sign.

Example: I have Pan Am typed in my Airlines.cfg, but the ATC will only refer to my Pan Am flight as flight "721" not "Pan AM 721". I'm referring to the 727-100 Pan Am livery as an example because I did a flight in the CS727-100 Pan Am livery yesterday and noticed it wasn't saying "Pan Am".

Listing the airline in the airline.cfg does work if you class it as allowing you to select it as the airline for the plane in the Details section as described in my earlier post.

I did look through the FSX SDK, but I didn't find much info on this subject. I will try a few things that I have thought of that might get it working. But....
