I think both analyses are right. Swiss in their A 333 has 8 FC seats and they make two available per flight from NYC to Zurich. I followed this for weeks and knew the exact day it would become available and actually snagged the tickets at 2 AM - yes, I'm as crazy as the rest of you.

But the economics of the whole FF thing is amazing to me. Yes, some airlines make more money selling miles than they do flying airplanes so they have no choice but to make some seats available, but I always feel like I "stepped in it" when I manage to get those FC seats for miles.
