Hey tyler,
I am a Delta employee as well, you can only take a personal leave after 3 yrs of continuous service, for up to 2 years. I dont think you should have to leave though. I am going to flight school in KFFC and attend online courses. You have many choices in ATL as well, GSU, GA tech you name it that you can stay local. I am planning on taking a leave when I find a flying gig wherever it might come from. The beautiful think about leaving Delta is that even if you quit completely you always keep your employee number. I am assuming you are prolly in ACS?
Check out,

At one point GSU had a flight program but I think they took it away a couple of years ago.
Just some ideas from a DL colleague on the same path.
