So in my journey to understand NC, i've come to the conslusion that the only point to utilizing NC is to potentially get a few extra dollars after they assign you a trip that is not permitted by the PWA. My second crew assist report that was closed, came back with "the departure time was after the first 2 hours so it was not a violation". So if anyone is thinking going NC will keep them from dropping a trip on you inside the first 2 hours, it really is a non-functioning provision as everyone in CS'ing interprets it differently than it's written. Not surprised either, just sayin'.
