First off, no.
Secondly, you didn't read my post carefully, or just didn't understand what I was trying to say. You and I are in total agreement.
How it works now is: When a vacancy opens up, there are no displacements. For instance if 10 captain slots open up in ATL, you might have 10 ATL guys upgrade. But more likely you have a few direct upgrades and a few IAD captains bidding over. They move to ATL and consequently their spots open up in IAD. Then a few people who have their bid for IAD upgrade up there (instead of ATL). The most junior IAD captain moves up, or at worst stays the most junior captain. The same goes for the most junior ATL captain. No matter which way you slice it no one gets displaced during a vacancy. A vacancy only causes upward movement. Only in a reduction do people get displaced.
Now that being said they could possibly come out with a bid say, 10 IAD reductions and 10 EWR vacancies. This will end up in a displacement of some sort unless you want to move bases. However, I think this is very unlikely when we first merge because that will guarantee a lot of training costs. Also, since we have 2 fleet types they can't just mix and match them. An IAD base with 10 CRJs and 10 ERJs just doesn't make financial sense.
The bottom line is if we are a 100% merged company with a single seniority list and a single operating certificate we should operate as a single entity--pilots included. It will be to the benefit of the vast majority of pilots for no fences. Unless there is a massive reduction you stay in your current seat and domicile. When Delta or whoever hires 100 people, we have 100 vacancies, and 100 people bid up. Just bid what you want and want what you bid.
