From what I hear SWA is not holding back expansion plans in PHL. It looks like in Sept Delta will be moving to another terminal in PHL & SWA will be getting 4 more gates in the E Concourse. Also right now the 2 gates in the D Concourse are for terminators & originators, but within the month they will be used throughout the day. The airport is trying to work out an agreement where NWA takes over these D gates & SWA takes over NWA's gates in the E Concourse. As I said don't plan on SWA not to grow in PHL.
