A couple years ago I was seriously contemplating leaving CLT for JFK AB and doing those two-day 321T trips, lines of them back to back for 24 hours pay doing one leg a day with no red-eyes. That stuff in CLT is like a 20 year wait on the FO side...
If you live in the NE and don't mind it JFK/PHL is by far the best bang for your buck seniority wise. But DFW has been getting a lot better too, it seems Charlotte is stealing it's thunder.
