Don't know the details on this but this brings up some interesting questions. I'm pretty sure the 3 NYC airports are the most "avoided" airports known to PBS and as a RES I can confirm that it's a close race between Chicago and NYC for the most pilots who always seem to come down with optical anal disorder whenever I'm on call (guys always seem to trooper through those 34 hour CHOs though...). So if they made this change, the guys who are bypassing seniority to commute to NYC will now just pawn off their garbage on the surrounding bases basically giving them a double bump in seniority. Take this a step even further, if NYC becomes commutable at the expense of a significantly larger portion of NYC layovers in other bases, will NYC remain the mecca of junior opportunity that it is right now? Sure, it will still be junior due to all the other reasons everybody knows about -- but as an ATL guy I'd consider commuting up there if I knew I'd be able to reliably fly double commutable trips whereas in the current state it's not even on the RADAR, and I'm sure I'm not alone.
