What subtitle? There's no subtitle at the top of the forum page that lists thread titles, nor is there a subtitle in the forum jump drop down menu at the bottom of FT pages. How often do people actually look at the sticky threads and announcements about what a forum should contain?

IMO it's counterintuitive to expect folks to figure out that budget airlines and LCCs should not be discussed in the first major section of FT that's devoted to airlines and their FF programs. It's even worse that a few such airlines, such as Southwest, do have their own dedicated fora, which appear in the list of all the other airline programs. Nothing says "airlines except for LCCs and budget airlines."

Changing the title of Budget Travel to stress clearly in the title that this forum includes budget airlines and LCCs (ideally as a sub forum) would be better than nothing, but IMO the logical structure of how FT is organized demands that (any) budget and low cost airline be discussed somewhere within the airlines/FFPs main section of FT.
