I took your advice and have made the changes you suggested. Thank you so much.
Mixed results. Some realtime traffic shows up with actual livery and some shows as A320 neo.
I will have to do some comparison on the liveries I have. Delta, Alaska are fine. But AAL, SWA are generic neos! United was always there even without the changes. Have not tried non-US airports yet.
Any suggestions? I do have SWA and AAL in my community folder BTW.
Just to add my current experience to my prior post:
I changed most of the aircraft.cfg with isaitrafffic=1 and now most if not all live flights use the liveries, albeit they are all airbus 320s, but so much better to see a live traffic plane displaying the same livery!!
Thanks to our friends here for guiding me in the right direction…
