Anyone know how many more flights could be added in CLT with the current gate space if the need to dehub PIT becomes reality? It would open up a lot more conx possibilities if many of the PIT flights were moved to CLT with some for NE conx moved to PHL. I know at one time there was talk of building CLT up to be much bigger. Maybe now would be the time to try continual hubbing there with many of the PIT flights moved there. With the code share thing going now too, how hard would it be to do some non US hub flying such as ERI-ORD or TOL-IAD with code share offerings on routes not currently served by UA express flights?
