Usually for each family we have thread to post the flight line. Do you want just to combine them into one?
In the first place I was thinking about the few posts in this thread. I did not realize there is a specific A330 Flight Line Thread, probably because that thread has not been used since April 2019. A thread for A380 is pretty useless nowadays. For the A320 family I can only find a thread "Production Line" but I guess that can remain in place, a "Flight Line" is quite something else
