Can anyone explain in a concise way that's easy for new guy to understand how this "new" 756 bid for SFO/ORD is supposed to work? I read it to mean UA needs 30 more positions on top of what they already have staffed in the 76T at each of those locations...but I guess it's more complicated than that.

More specifically I mean, aren't all the 76T folks just going to be converted to the 756 in general? I guess it has something to do with only 50% can be forced to and the rest need to bid 756 if they want to stay there? IF that's the case, then this vacancy bid could possibly, in effect, have no vacancies at all since 30 current 76T people could just bid over to the 756? And then there would be no back-fills to the 76T since it is "closed." Some 76T folks are showing up on the 756 bid on snap 1. This just seems to skew the numbers and I'm thoroughly confused...which is easy to do I guess.
