If we can believe what ir has said on conversations in the past, my post makes since but isn't to be relied on of course. I say this because ir has told a couple of us here in the past that if A (concession imo) happens, then B (c class shares imo) can be possibly negotiated and happen, and finally C (revs and pps appreciation imo) can happen. In other words A+B=C. I guess we will just have to wait and see.
