If this is meant to be a suggestion specifically for the UA forum, you might want to contact the mods there and see how they react to the idea.

If it's a more general suggestion that many of the airline fora on TB should be reorganized, maybe it would be useful to clarify the vision of how various airline fora should be organized. For example, is this meant to apply only to USA legacy carriers, all major airlines/programs, or every airline forum, including airlines of India, airlines of Russia, other North and South American, other Asian, etc.

The AF/KLM forum is already somewhat organized this way in that it is divided to three subfora: the FB FF program, AF, and KLM.
