From what I’ve read elsewhere, things are not quite as rosy as you would have us believe between the DL and NW pilots… despite what you claim! While it has not been so acrimonious as with AAA and AWA, as has been said here before, the LOS differential was dramatically less in most cases. Further, as I recall, this seniority integration had 3 arbitrators not one and the contract had already been negotiated before the seniority integration took place so everyone knew exactly what was in store for them before hand.
It was ALPA’s structure, not clearly defined merger policy and FUD that created much of this mess… and yes it did involve the local MEC… the majority of which was made up of the give-away gang!
