What about the guys that would be holding that position but can't because the sub 1000/100 guys are still in the position? Will they just overstaff that position until they can effectively displace them or will the guys not flying their awarded position receive bypass pay?

IMO, this is yet another thing upper management didn't even think about when all this went down. I'm sure they'll choose to put these pilots in the LAST training class possible hoping they make it to the 1000/100 mark. Tough to do when you're starting with some of these guys in the mid-200 to low 300s in total time, though.
