I agree with DLax that the vacancy bid makes sense. Especially since the MEM 757 is not being 4A2b'd in the same fashion as the rest of the fleet. Those folks are already flying A LOT and with a growing fleet and more airplanes to fly they are going to have to put more bodies there. I mean unless the company finds a way to put 40 days per month on a calendar.
I think the bid is coming... and sooner rather than later.
