I support a sub-forum for Premium Fares, simply because the current thread is unwieldy and impossible to concentrate a discussion on a single fare. We tend to have discussions in the thread about a particular fare and the actual premium fares get lost amongst those discussions and leads to a lot of moderator intervention.
A good analogy is the desk of a messy person. He likes it that way because he actually knows where every little thing is on his desk. But, most just find the desk cluttered and barely usable. If someone were to clean the desk, most will find it far better, but that messy person will be upset because now his system has been ruined and he can't find anything.
We need a clean de-cluttered forum for it to really be useable.
