To get some of them to work. Open FSX. Go to Free Flight and change the current aircraft. HIGHLIGHT the Captain Sim 767 livery you want and then select DETAILS. In the Airline call sign: select the one you want. Then change Flight number: to the number you want. e.g. Select 767-300 British Airways. Then details. Then in Airline Call Sign, select Speed bird from the list. Then in Flight number, type 763. The ones listed work.

Well, I tried it but not appears any new airlines except the originals ones from FS, i.e., Orbit, American Pacific, etc.

I agree with you it would be necessary to modify the "aircraft.cfg". And I tried it too, but Windows asked me to choose a program to open it and I don't know to do it.

How do you open the .cfg's files? If possible, step by step.

I told in my first post I'm a rookie in add-ons, and I never tried to modify the FS's .cfg files before.

Thanks a lot.
