SWA's current CEO is different than Herb and Colleen in the sense that he's been tweaking the SWA model. Gary Kelly has told the company and the investors that WN needs to go into some cities that were avoided, ie LGA, BOS, MSP, etc to attract Business travelers. They've enchanced their product on Business Select, giving them the opportunity to board first, get extra credit and a drink. When they went into LGA, many questions were raised about delays, and WN stated that they have built that into their model.
Not sure what department where you work and if you are in CLT, but I can tell you that in PHX and LAS, during weather delays and cancellations, LCC is a very good customer of WN. When bad weather hits WN, it depends on the situation and the delay, but it's not unheard of them reroute customers on other carrier's, but they don't do it at the drop of hat like other carrier's do.
I think that a couple of factors hit WN in PHL. PHL did accept WN and they didn't kill LCC, but they faced limited airport space and a huge recession. They adjusted their schedule system wide, dropped 10 flights out of PHL and LCC took it as a sign of retreat. Only thing is that the airport and WN have now remodeled and added new gates to offer a better experience. They have directly chosen a overpriced route, BOS/PHL to return service. From past experience, WN schedules 10 flights per gate per day. I think that this is only the beginning of more service returning to PHL.
