Unfortunately Piedmont doesn't have a Philly base anymore. However, I live in Buffalo and plan to commute to LGA for PDT once I hit the line (hopefully in a couple weeks.) One guy I know works for Eagle and absolutely hates commuting to LGA for his trips. On the other side, I know a few people at PDT who don't mind commuting. They still have a lot of day trips but with a crashpad it isn't that bad.
