My wife and I flew to PHL on 4/22 and returned to ATL today--in fact, we're onboard right now. We were both upgraded in both directions, and in both cases the boarding process seemed smooth and easy. No cattle call, in fact, not much different than previously. On the flight from ATL, they called FC before saying Zone 1. On the flight from PHL, they just called Zone 1, but it didn't seem any different than the flight from ATL. I will say that we tend to be "in line" before the fact so we typically are among the very first onboard, but so far this hasn't been a big deal to us--even though I still think the system should be modified to board FC before everyone else.
