For the most part I like PBS though it could certainly be better. I am a junior (60%) line holder who does not commute so I am easily able to get weekends off and even get some of the layovers I like. If I commuted, I would certainly have to sacrifice my weekends in order to get a more commutable line. If your company is considering it, make sure you do not give them a blank check! It is imperative to get very clear parameters set with regard to pairings, number of reserves, adequate staffing and some percentage of uncovered pairings in open time. Get the rules in writing or you will be sorry!
