I'm hoping for the 737 or 320 as a NH. I'd like to be based in ATL but I may have to commute to LAX, NYC, or DTW for awhile until I get awarded ATL. All three of those bases would be a 2-hop for me (OKC). I know DTW doesn't have co-terminals, but what is the co-terminal situation like in LAX and NYC for those aircraft? Any tips for commuting in to a base and sitting reserve for multiple airports? Which aircraft/base would be the least stressful? Are reserves being used or are pilots sitting around in hotels and crashpads on short call?

Thanks,
