There are bases you can move to that make it easier to work with. If you were living in CVG for example you could move to CVG and stay there you're entire career once you could hold lower 48 on the 747. MIA and ANC are the same way. HSV, LAX, and JFK you never really see your base after maybe day 1. PAE is sort of a mix. IAH is very Senior and the stuff you'd hold being junior would spit you out immediately and you may never see IAH on your trip. Reserve is quickly converted into a trip most of the time so that doesn't help much. That's if you were planning on staying at Atlas.

If you're planning on leaving anyways then you'll probably be gone 19 days a month because of the commutes on day 0 and 18 to ANC.
