Could anyone share some insight on how the line improvement window works? I understand it happens after the initial bid is awarded, but I'm not clear on what is being "traded". Does the company intentionally hold trips out of the initial bid and put them in "open time" so that people have something to trade with during that LIW, or is it something else entirely. And are these trades happening in "real time", with people adding and dropping constantly while the window is open (meaning the pool of available trips to trade is constantly changing)? I've seen posts where people say "I was awarded a line with 12 days off and 95 hours, but during ILW I traded to 19 days off and 65 hours" (or something along those lines). Is it fairly easy to get more days off during the ILW, even if your junior? I know you may lose hours, but I'm more concerned with getting a better schedule (more days off, more commutable, etc.). I know it's probably too complex to spell out completely on a message board, but some general insight into how it works at XJT (and how well it works) would be a good start. Thanks in advance for any input!
