In my case I have the SAS livery for the -600 model. The text file that contains the needed addition for the aircraft.cfg was located in FS2002aircraftPMDG737-600 and was called "SK Add me to config file.txt". You

Found it. Thanks. These old eyes of mine don't work so great anymore:)George

I found the Southwest livery text in the .....FS2002aircraftPMDG737-700-Winglets folder. It is a simple text file and you can copy and past the entire contents to the aircraft.cfg file in that same folder and apply the correct number to the fltsim.x in he aircraft.cfg file.Hope this help's.Steve ParkKSDF

In the instructions for the add on livery that is available, it says to copy/paste the XX_ADD_TO_AIRCRAFT_CONFIG_FILE.TXT to the aircraft config. Where is the XX_ADD_TO_AIRCRAFT_CONFIG_FILE.TXT?Guess I'm an idiot (or been up too long enjoying this fantastic new addition) Thanks,George

You should note that just copy and pasting the config stuff from the file only adds a 2D option for that livery. If you need VC, VC+Stairs, or any of the other options, you will need to change the model= and the panel= lines :)
