The latest info that I heard was that they expect to drain the pool by around January next year. There are already a fair amount of pilots that have done the meet-n-greet that haven't been interviewed and that depending on when they did the MNG they could expect interviews also in early 2007. As for meet-n-greets, there might be a window again before the end of 06, but if I were a betting man, I might say after peak...ie in '07.
I suspect that it depends on how many they have in the "to be called for an interview" pool.
Nothing concrete here, but generally, I think that you'll see things start moving after peak.
