PAY OFF THAT DEBT! You're already only flying once a week so just keep doing that while you pay the debt. Cut the fat out of your monthly budget, things like eating out add up really quick, and throw that extra money at the debt.

If you are planning on making this a career it's best to start on first year pay without any debt, it will help you in the long run. Think long term, by flying 2-3 times a week you are essentially financing your flight training in the form of the interest you pay on your debt. Flying once a week is a small sacrifice to make in the long term to pay off this debt. Once the debt is gone you will be amazed at how much more freedom you have with your personal finances and you can probably fly 3-4 times a week. Just my $0.02, probably worth more than the $0.02 in your pocket right now
