Max unshackling- Alaska already has that...it is called no unstacking.

Trade to zero - Alaska has this also.

Maybe you meant drop to zero maybe? If this is NOT dependent on some coverage formula/staffing chart then it is a benefit. If not, than it will turn out to be not very useful. Right now I can technically drop to 75 but none of my trips are droppable. I think it would help the senior guys get not only weekends but weekdays off too. It won’t help the guys on the bottom of the list at all.
