"At least three from corporate and as many as 20 from the schoolhouse" If this quote is accurate then the lost of seniority associated with delaying the transfer to the line could easily be a lot more than 2-3 positions if most of the 23 professionals/corporates decide to come to the line. Giving away 15-20 seniority positions could be a crucial deciding factor in future aircraft bids, upgrades, vacation, monthly bids, etc. If they don't come to the line on time, are they still covered by the original contract or do they sign a new one? Tough decision but I think I would come to the line and get on the seniority list unless I had some really solid intell saying it was a bad deal. The fact one pro has already declined to come to the line suggests this may have already happened and the intell was not favorable. I don't know how he/she could have made an educated decision since our Union, CP, Mgt and VPs haven't shared anything of substance about 2009 crew manning, other then a potential excess bid. JMHO
