After many horrible recent experiences with connecting through PHL (to and from PIT), I will not connect through there willingly ever again. I have waited for later flights when offered earlier options that connect through PHL. I will fly any other airline to avoid PHL (and do so more often than not)
Also, after many recent trips paying extremely high prices for short RJ trips and trips with inconvenient connections (also at high prices), I have booked for next week PIT/MCI, outbound on United with a convenient ORD connection, and return on Midwest NONSTOP....WOW!! And the topper is, it's the lowest price I have paid in many years for any ticket. Better service and connections, nonstops and lower prices on other airlines....maybe the other FF's here are on to something.
Lastly, as Jimmy references above-the responses from management where we hear you but don't really care, that's basically the same response I got when I emailed Executive Management very recently.
