Why are you moving to PHL and attempting to get a new job not necessarily based in PHL?

Commuting is absolutely horrible. Commuting out of PHL is downright torturous. It is one of the worst airports I can imagine commuting through. Not to mention trying to do this while a reserve probationary regional FO. Life is going to suck for you.

Get hired somewhere and pick a base that seems stable and that you could live at. Move there. Don't commute.
