What to do about flight plans ?

HowdyI need your advice. I have all the PAI auto installed schedules installed everything seems real good but of coarse many airports are quite sparse. I would like to get more airlines and schedules running but I remember the lengthy process it was pre PAI. I am currently working on a gmax scenery project and would hate to get sidetracked, devoting too much time to this but I feel I can't wait any longer for the rest of the auto-installers. So I ask, what is the best way to put it all together? Has anyone made available their PAI compatible flightplan and aircraft files for compiling ? Can it work that way ?SteveCYYZ
