Of all the flights to threaten to cut if US doesn't get the gates to themselves, isn't it stupid to suggest that they will move the PHL-China flight? Can US even switch from PHL to CLT or PHX? I thought that the China route awards were more restricted (and conditional - could the DOT take the award away from US if they try to switch PHL-Beijing to CLT-Beijing?)? To me this seems like US is pointing a gun to its own head and saying: "If you don't do as I say I'm going to shoot myself!" IMHO it would be better to threaten to move some of the Europe routes to CLT (or PHX) since EU is more or less open skies. Regardless, I think the city of PHL has the upper hand here, I think they know that there is no chance US is dropping/switching the PHL-China route.
