There will never be anything to "point to" in ANY public offering regarding pricing and how much of each fare is bought by whom - that is very closely guarded by the airline.
That said, I can say having worked for an airline for nearly 10 years (not anymore of course) is that it certainly ain't Joe and Jane taking the kiddos to Disney World that the airlines covet unless they are filthy rich and paying full fare F to get there. Business travelers - those who pay for the higher fares for flexibility - very much drive the revenue of most airlines in the US (even Southwest).
