Here's what I mean, short story, just look at Net Additional Airplanes, Lost Jobs and Pay Difference. Option B is 717s as pure growth and Option C says not so fast, 717s/CRJ-900s replace MD88s.
I hid a bunch of the other options for clarity. FWIW, the 739s are in there as a 1:1 replacement with the 100 oldest 320s, 763s and 757s and so it takes into account the hits with ASMs there and parking the CRJ-200s.
