The Jepperson/Carmen system will be seniority based in the way it constructs rosters. The look and way crew will bid will be totally different but it will expand options for crew and will quite possibly actually give a better quality bid run still based on strict seniority.
the only way that the FAAA elected officials will negotiate changes to the system will be if the majority of crew on the current system (part 1) by a greater than 50% margin petition or vote for change.
I find it difficult to believe that those criteria would be met. It doesnt however stop the company from creating mischief with flight attendants by stirring them up and suggesting that there are better options available.
