ATL is senior, some 2008 DOH's on RES. DTW is middle ground most JR line holder is 2008 DOH, IAD is junior, most JR line holder is 2011 DOH (I think even a few 2012 DOH's held a line). But with DFW in play now... hard to say but I think you all will fill the bottom of all 4 bases. I am an 2008 DOH and I'm on the upper 1/2 of the FO list in IAD, I'd barely hold a line in ATL/DTW. Your question would be better answered after we bid DFW.
