Starting class next month. Currently live in Pittsburgh and debating between DCA or PHL. Want the option of international so that's why lga is out of the question. Plus I need a break from NYC as I'm based there with my current airline.

Wanted to get some advice/opinions on either phl or DCA qol and trips. Driving isn't really an option unless in a pinch(3.5 to DCA and 4:20 to phl) and phl has mainline which allows to reserve the js if need.
