Sallie Mae, and many other sources for flight training loans, curtailed loaning after a major flight school went bankrupt (leaving many students heavily in debt, with no training that would help them ever pay it back). As others mentioned, you can try going to an accredited school and getting a degree at the same time. This is not a bad idea, if you don't have a degree and want the education. It will cost you much, much more than straight flight school alone, but the degree might help you out down the line.
When Sallie Mae cut back on loans, our school started providing financing for students. Usually they are competitive with what Sallie Mae was offering. We're doing it because we think the economy will come back, leading to many boomers exiting the industry as their retirement accounts rebound. That's going to start the hiring process up again for new helicopter pilots. You can get info on our financing and loan program for helicopter flight training at helicopterpilotloans.com.
