We have a winner? Puulleeaasseee. Trying to convince anyone that the -9s are not going away is just ludicrous. They are, what's worse, there are now. So, yes, that matters with regard to the jobs that NWA pilots bring to the table. It is not YOUR seniority, it is OUR--collective--seniority, and it must be distributed fairly. Part of it will be that NWa pilots take a hit for the loss of these airframes.
As for the -80s going away "someday", so will the 777s as well as the 787s. Unfortunately, none of these dates are specific like they are with the -9s. You are grasping at straws like your buddy Occam.
As for replacement aircraft for them, and NWA not being proactive, indeed they have been proactive--replacing them with Rjs. Unfortunately for NWA pilots, that was the plan over there, and does not bode well for the jobs brought to the table. That is what counts, not whos fault it is or isn't. NWA pilots aren't to blame, yet they are indeed victims of the circumstance, which directly corresponds to jobs, which cuts into the seniority arbitration.
Trying to leverage your DC-9 pilots away due to the drawdown of the aircraft is EXACTLY what is relevant in this arbitration.
..and superpilot thinks we have a winner. Grow up little boys.
