I agree with the other poster --secondary screening at PHL may mean a quicker trip to the lines.

I've been "disabled" for the last month or so and always get the special security treatment. Although I must say the PHL folks are getting much more lax with their screening of me... I guess they figure after checking me out 3-4x/day, they're sure I'm not some terrorist. But even before they slacked off, I and the other SSSS's were rushed through the lines/process there.
