This is a very good question and one that will have a large affect on the relative seniority of all of us. I would guess, that if DTW and CVG are closed or downsized:

ATL M88 will start going much senior, many of the CVG guys will choose this over NYC

ATL 76 ( all platforms) again more senior as the CVG guys move south

NYC ER will have some of the senior CVG guys going over there, probably only those who hold pretty senior lines. This of course, will push down those on the lower part of the NYC ER category.

NW and DELTA pilots changing bases? I would guess that LAX fills up quickly with NW guys who live in California.

If we get to keep CVG or DTW than those guys will likely cross over to the other bases.

This is just my guess. I really hope it works out for all of us!
