628AU,
You either misunderstood me or misunderstand the rolling hub concept. I never said we should become a LUV clone. I did say that an efficient hub of the future will look a lot like LUV in BWI, etc. A steadier flow of flights than we have at PHL, but not necessarily spread out evenly throughout the day. And definitely not becoming point to point with PHL, CLT, or PIT happening to be one of those points. Depeaking has nothing to do with O/D traffic, it is meant to decrease the time your planes sit on the ground not producing revenue. If you could get one more segment per day from each plane, the CASM for those segments would be dramatically reduced since the only additional cost is DOC.
If you'll read my statement carefully. see the "while needed in some markets"? Yes, the aircraft needs to be matched to the market. Cost per segment does matter. However, it is also true that RJ's have a higher CASM than larger aircraft. So if the market will support larger aircraft, it is foolish to use RJ's.
