I think splitting things up further would create more confusion than it would solve. And, although there is some discussion "about" the fares (rather than just posting the good deals) in the existing thread, I don't think there's so much of it that a new forum is needed.
Remember, if a new forum is created, then every single fare will need its own thread. That seems like overkill, especially when lots of these fares generate only 1 or 2 posts.
