I'll give rick a break from his usual speech and summarize it for you:
Go to school in something else you want to do (ANYTHING...even underwater basket weaving). Pay for that. Get a job after graduation and pay your way at a local part 61 school getting your certs and ratings part time. Then get a CFI gig to start building hours. Only THEN should you apply for airlines. You go into a subpoverty level job with no debt which is better than going into said subpoverty level job with 45,000 in debt.
Sorry rick if it wasn't as eloquent as you
I've only said it a few times.
Regardless, unless you have mommy and daddy backing you financially you might not even make enough when you graduate as a CFI to pay your INTEREST payments.
