ATL would be an easy commute to MEM or to deadhead anywhere on the east coast with the Delta hub. As far as the week on week off, that seems to be the norm for commuters since it cuts down on the amount of commuting each month. I commute and I love the week on week off schedules. There are lines that have a variety of trips that are shorter than a week but it would certainly be tougher on a commuter. It's your choice. That's the great thing about this company, you have a wide range of choices to choose from. As a junior pilot you will not have much of a choice of reserve lines and some of those are over a week long at a stretch, but in return you will have a lot of days off at a stretch. Just like anywhere else, quality of life comes with seniority. Hope that helps and good luck.
