We were longtime SWA fans, but have moved on. There are few, if any, non-stop flights from PHL, and its been that way for a while. We finally just gave up. We have been booking with American instead (happy to have an alternative). The fares were comparable, but I don’t want to spend a good part of my vacation time making connections when a viable non-stop option is available. We use our AA credit card to book, so there are no baggage charges. And the seats were a tad more comfortable (subjective, I know, but I’ve always preferred Airbus planes over Boeing). I would love to know why SWA seems to consider PHL an after-thought these days….the terminal was always busy and the flights were packed. We last used them in January 2020 for a WDW trip and managed to get non-stop flights (the times weren’t optimal, but you can’t have everything….).
