Don’t pay good money and go into debt to get training the USAF is going to provide for free. Pilots are in demand. If your unit wants a PPL for you to be competitive, that’s as far as I’d go. Getting anything more is ridiculous double effort/cost and may actually make your UPT experience more difficult. Lots of civilian time and training is no guarantee of success in UPT and often means having to unlearn things in order to readjust to the USAF way.
