I'm not so sure that it's a 2-way street. When I worked for NW, I had the same priority on all flights as a mainline employee, but employees at Mesaba (a wholly-owned subsidiary of NW at the time) had a lower priority than we did, at least on mainline flights. Then again, for CO specifically you probably know the ropes better.
