The APL MDA pilots were on the AAA main list so they were in Nicolau's purview by default...
ALPA's biggest dilemma that they have ever faced is that they have to come up with enough money to payoff "Junior" pilots to hose themselves.
Yes. ALPA represented the MDA pilots. That is obvious. That is part of the point.
MDA pilots had a dispute with ALPA concerning their status as Mainline. However, MDA pilots did NOT submit to Nicolau with respect to arbitrating that dispute between them and ALPA. ALPA has a conflict of interest and CANNOT submit the MDA pilots for arbitration of that dispute as a subordinate issue to be subsumed by the merger process arbitration.
If ALPA presumed to submit the MDA pilots for that purpose then they are culpable and Nicolau's ruling is invalidated, if his award included a determination of that dispute.
On the other hand, if ALPA agrees that MDA pilots are in fact Mainline (as they have done previously on numerous occasions) and maintains that they told Nicolau as much, then they are forced to observe that Nicolau failed to adhere to the facts as presented by ALPA and that his award is invalid.
Regardless of how ALPA wants to try to step out of the line of fire... No matter what decision ALPA takes to defend themselves... their action will by definition oppose the Nicolau award.
The easiest way out for ALPA is to payoff the MDA pilots to agree that they never were Mainline pilots. But that presents ALPA with a problem they have not faced before.
This most interesting dilemma was already mentioned by EMBFA. The most junior pilots, who have been sold down the river many times by the senior, now appear to have the most sure legal footing to stop Nicolau's award.
The East pilots are adamant that Nicolau's award will not be established so it is in their interest to support the position of the MDA pilots. But even if they opposed the MDA pilots, you can't payoff the senior pilots to hose the junior pilots, because in this situation ALPA must payoff the Junior pilots to agree to their own hosing.
ALPA's biggest dilemma that they have ever faced is that they have to come up with enough money to payoff "Junior" pilots to hose themselves.
My understanding from the AWA MEC chairman is that the arbitrator chose amongst several, if not many lists.
If true, that might require revision of the quoted statement by you.
Does ALPA agree that they presented "several if not many lists" to Nicolau, and that they pledged to accept Nicolau's ruling on which seniority lists was the "real" ones from which he would then decide how to join the two?
Did MDA pilots agree to have Nicolau arbitrate their dispute with ALPA concerning their status as Mainline USAir pilots?
