Song was Leo's brilliant idea, and I would say it could be done (although very differntly) even with a contract. The difference would be it would have had to run similar to the shuttle or express, all on one bidsheet and one seniority list (obtain Song quals and bid those lines) .
So if iam reading you correctly, A contract wouldn't have prevented Song as a WHOLE, BUT it
would have protected F/A's in those bases. They couldn't Divide the F/A group if we had/have
a contract.
