Just did a quick scan of the category lists. (this is all FO thoughts).

NY is much, much more junior than anything else (obviously). DTW and ATL are at comparable seniority. I thought that DTW would be more junior. The 330 compares with the 767-400 in ATL, but the DTW 757 is much more senior than the 7ER in ATL. 320 is more senior than the -88. If DAL-N people want to get senior quick...go to NY! You could easily be 50% on the ER, 50% on the 73, and 25% on the 88.
