I have heard so many pilots here bragging about intentionally timing out to have the last legs removed from their trip. If you want high time productive trips, you have to be mature enough to actually fly them, unless delays that are out of your control cause you to go over the limits. I am VERY confident that those on this board compaining about the loss of productivity would fall into that same group...
In addition, I think it is common knowledge that the company is trying to IROP proof the pairings by not having them built up near FAR limits. While we have lost considerable productivity (which sucks), we are not (yet) dramatically behind the productivity of other narrow body pilots, other than SW that is.
One of my personal top priorities for a CBA is a strong 5.5-6+ hr min day. That will help pay us for our time away from home.
