I'm a little curious at the assertion that Charlotte would have a signigicant net reduction in flights (we are bound to gain flights to cities such as Oklahoma City and maybe some other Midwestern and Gulf destinations...).
I have seen some people post that Americans high cost wont work with Charlotte. My question is... With Charlotte being above and beyond the cheapest airport to operate a large hub, It tells me that Charlotte would continue to be a crown jewel in a combined network. Obviously it is likely we could lose some long haul service (unless AMR has a lot of metal to play with) but other than that, I don't see us losing any net service.
I also don't buy the theory that Chicago and Dallas will steal East/West flows from Charlotte. I actually think Charlotte's East/west flow will grow in a combined entity (Again... There is NO WAY Charlotte wont get service to Oklahoma City and I'm sure some western routes would also be added), For every route that is better serviced via Dallas or Chicago, there is a route served better via Charlotte
As far as Philadelphia goes, I also see Philadelphia being "the" airport of the North. I see PHL being much more prominent than JFK/LGA. There is no way JFK could take even a fraction of what Philadelphia handles. I think Philadelphia would not lose any services to JFK. I think PHL will continue to get international destinations that JFK doesn't have. EL AL is a Star Alliance member. Why fight for the Tel Aviv market, for example, with United who has the Massive Newark hub and El Al who has a hub in Tel Aviv and Delta flyng JFK-Tel Aviv (If I'm not mistaken, which I could be) when you have a massive O&D market all to yourself, a huge 400 flight hub, more pricing power with O&D traffic VS. a Focus City with a lot of competition...
I see Charlotte, Dallas, Miami, and Philadelphia being the crown jewels of the new American. I wonder what role Tempe has in mind for Chicago. I know they don't like competition.
