You may want to look into it but I believe you can't use the GI Bill to pay for your PPL, just certificates after that. Also, you may want to consider the fact that come August 2013 you will be required to have 1500 hrs and an ATP to get into the regional airlines as a first officer. However, if you have a aviation 4 year degree you will only need 1000 hours. It took me 8 years to get a 4 year degree because I worked full-time and did my flight training at the same time. The regionals don't require a college degree and everything is based on senority number. The sooner you get in the better off you will be. If you are totally focused on being an airline pilot I would hold off on college and try to get in by August 2013. While you are a regional pilot you can work on your degree on-line. Good luck.
