I have a flight this summer departing from CLT; almost definitely on USAir. I've never departed or arrived CLT, but I've transferred at CLT countless times, so I'm well aware that once you're airside, you can get to any gate.

According to tsastatus.net, the C checkpoint is safe.

Question: when I check in for my flight, I will obviously intentionally seek out the C checkpoint. How far might I have to walk to do this? And will the TDC care if my BP shows my departure gate in a concourse other than C?

Thanks!

(Second question: I also have a departure from PHL this summer, and apparently, D is the only safe checkpoint. If my flight check-in is in another terminal, can I walk, landside, from check-in to terminal D without going outside?)
