As Brownslave688 said before, FT employees can transfer in Local 688 without losing seniority for an area wide bid.
The other way would be to ask for a 4th move giveaway. 1st moves are area wide bids, 2nd and 3rd bids are in center bids and the 4th move is a giveaway (ask from top and force from bottom of the unassigned). He can ask the company to allow the 4th giveaway move. They are not contractually required to allow the giveaway transfer. After the 1st move it must be classification only too (package>package, feeder>feeder and Art. 22>Art. 22). This would be the only way to get a decent route with 12 years in.
