Yes, a little perspective can definitely go a long way. You ask how many east pilots have sat down to see how their bidding position would change with the Nic. Believe me, many have. Of course the immediate effects would be minimal, but as you yourself point out, down the road many east f/o's who would capture captain seats when us old farts retire (eventually,) will be blocked forever from that upgrade by younger, more Nic-senior west pilots. That's the rub, and it's the real future for hundreds, of east pilots.
But the real perspective that we on the east have (that the west does not...not due to any deficiency on the west pilots' part) is that old chestnut "expansion." We have been the incredibly shrinking airline for more years than we care to talk about. Think about it. How in the world do you think our geriatric seniority list got that way? Expansion? We are where we are simply because of clueless management types who promised all kinds of rosy scenarios, but delivered NONE. What's more, they usually delivered the exact opposite of what was promised. This is the perspective that the east pilots have. If there were guarantees of huge expansion, sure the effect of the Nic might be ameliorated to the point of becoming moot. But there are no guarantees of expansion no matter what we are told. Been there, done that, had enough, thank you very much. We have been in the shrink/stagnate mode for lo 20 years, and the Tempe brain trust does not seem to have a different playbook from our perspective.
