Hello VVingLess,
I see you live in the United States so your question is quite easy to answer. In the United States to fly for the big airlines like Delta America etc. you need atleast a 4 Year Degree. Even if the airlines don't specify it they do prefer it. There are many ways you can train..
1. Go to Flight School get all your ratings (CFI aswell), when you are done attend a college and instruct on your free time.
2. Go to a College with a Proff Pilot Program and get a degree at the same time.
3. Go to College, get a degree in a non aviation field and then attend a Full time Flight School.
The First one I think is the best because you will get your foot into the business early. Its up to you...
Any questions feel free to private message me.
Good Luck!!!
