The thing is that under your scenario Buck in SEA the 330's would be moved to other bases. IE displacements. The only way for them to bid back is for there to be an opening on the 7ER after SOE.
Lots of stuff will scatter as we try to realize all the potential of this merger. When and where we go is of not much consequence to the masters. It is now about the bottom dollar. We agreed to our compensation and now we are good to see how they use us.
Like I have stated it is possible that bases would be opened up. It is a lot of money to DH crews out to SEA for Two years. It is easier to pay for a one time move. (They may be betting on the fact that many will not move)
