It's all a crapshoot. If you want PHL you gotta be a RP 170 driver. Anything else and you'll have to wait to upgrade there. They're hiring into everything. You can always ask for a specific certificate or airplane, and you can always pass on a class date to wait for something on that certificate...but it could be dangerous. Do what you gotta do. AWAC also has a PHL base if I'm not mistaken. My friend there is pretty happy.
