I had this same issue after purchasing the A319 and went into GSX config, airport and set it to conveyor belt in front and cargo in rear. I still have the problem, just cargo load and no conveyor truck in front or luggage vehicle? Any ideas I can try? I did the main installer, but no effect.
I did notice that its only on the Aerosoft A319 and not on the A320 at the same airport and same gate. I know I am close.....
I hope the answer isn't the A319 doesn't load any luggage in front? Cuz now I feel stupid...
Thanks for your help.
