I doubt PHL will become senior. The opening of PHL was a smart move for recruitment. It's strategic to keep PHL junior by increasing the lines and trips based on the pilot demand. If it gets senior, more lines and vacancies can be added to bring it back towards the junior side. DCA is proof of this model, it's not a big base but large enough to stay junior for captains and FOs.

For new comer planning purposes, I would assume you can get PHL shortly after training and hold it as a junior CA.
