About Info on airlines and being a flight attendant

Okay so when i graduate high school i really want to become a flight attendant. (But i want an actual career in psychology. ) soo i WILL be attending college DURING my flight attendent career. i heard that is possible. can i still get my degrees as fast as everyone else if i take alot of online classes and dedicate myself to keeping up with classes? Also i am not sure what airline i should choose? i currently live in California around san luis obispo and the nearst large airports are LAX and San Jose. So i would probably have to relocate wouldnt i? I can do that thats not a big problem but i do want to pick an airline that travels internationally. prefably to places like france because i am currently studying that language and i do want to someday move to france for a few years. What airline does that? LAX would be the best base for me because i do want to stay in california but its so expensive down there! so now that you know my situation if you have any better ideas or suggestions pleeeaase let me know!!!!
