40 mil pax a year...doesn't matter if it's o&d or xfer, the airport still has operate like one of the big boys to accomodate that volume of traffic...I just don't understand why all you airline superboys hate CLT so much, it has been a poven hub for US and may continue to be, if down the road it does not continue to be a viable hub then that will benefit the flying public with lower fares...
I doubt that anyone here hates CLT. I'm impressed that Jerry Orr and US have built CLT into one of the world's busiest hubs despite its medium-sized metro area population and fairly low percentage of local (O&D) traffic. Discussing the obvious - that most legacy hubs in cities the size of CLT have been downsized/dehubbed over the past 10-15 years - does not equal "hating" CLT. And despite the relatively low percentage of local traffic, US has managed to squeeze some pretty high yields out of those too-few local passengers.
The US Airways mantra from Parker and his fanbois for the last few years has been that AA really needed a Southeast conncting hub to enable AA to compete with UA and DL. Even if that's true, connecting the NE to SE domestic passenger (or even Jamie Baker's hypothetical RIC-JAX passenger) does not require a mega-hub with 600 flights a day. Of course, if it's downsized, its efficiencies probably diminish and would enable competitors to grab more of the local traffic. As you pointed out, that would bring down fares, further hurting the hub. All in all, no easy answers. But as hubs go, CLT is hugely overserved, even compared to the other overserved hubs.
