That's one of the reasons why we (DAL) went with our vendor (Navtech). No globalization, and the system merely estimates the number of lines it will create--the system is not bound to create a certain hard number. It will not create more lines if it takes seniority violations to do so.

For those wondering, in this case a seniority violation-centric sytem, if you will, would take a desirable higher time trip off a senior guy's tentative line so as to give it to a junior guy and give the junior guy a just-legal line; at DAL we would rather the junior guy get a reserve line than the senior guy not get what his seniority allowed him to get, all in the interest of "creating more lines."

Okay, I am not an AS or AA guy, so I will bow out of this thread.
