PBS is a computer algorithm that will optimize the schedules for the benefit of the company. Obviously, it will have to be set to respect whatever parameters may be in the contract, but this is already done with regular lines as well. Some people will be better at bidding using PBS and putting in the right options the right way into their bid, so they'll come out ahead, while others who aren't as good at programming PBS will come out behind. Everyone who has used both line bidding and PBS seems to like line bidding better. Think about it, the company isn't spending money on PBS to create better schedules for pilots, that's supposed to be the union's job. The first month or two everyone is probably going to be p1ssed off.
