The optimization of the pairings is the root of the problem. I am not blaming the SIG. Crappy trips make crappy lines.
Somebody already gave you a good rundown of the problems in this bidpack. The company produced these pairings to control costs related to the contract I would assume. If the cost savings are realized, then I am sure these lines will be the new status quo.
I would urge everyone to express their feelings (yes -for or against) to the SIG, so that they can provide this direct feedback to the company reps. At least give them something to show the company that the displeasure is real.
