I personally think that there needs to be an Airlines forum and a FFP forum (maybe by slotting the airline in the proper slot under Global Airline Alliances?)
I'm mainly in the AC forum, and there are a lot of threads about AC and not AC's FFP. To me, it would seem that the AC FFP forum is the best place to post about AC, even if it's not about the FFP. This has made the forum pretty messy, especially since AC has subcarriers such as ACX and ACR.
