Wouldn't a mix of the NB fleet throughout the bases just aid in making the operation more efficient? It's not like you have to do anything to add a 320 ATL base or 737 DTW base? I mean I get myopic looking at ATL 88 which is massive but when you look at the staffing on some of the bases it's amazing how few pilots they have to have to make it, albeit in some cases barely, work now. MEM comes to mind.
