I have never personally known of anybody getting an off-the-street OTS Pilot Slot without a PPL (I'm sure there are a few)...but OTS also used to be a much larger pipeline until it was cut in half in 2005. 10 years ago you wanted to have a Commercial to be competitive. Prior Enlisted kids do get slots without PPL, but there was no reason to put-off your PPL before applying out of college.

Really, I am blown away that in this day of ultra-limited OTS slots that some one would tell you you were super competitive without a PPL.

However, like everybody is saying keep fighting. It took an extra 2 years and fighting with the Flight Surgeon world to get my medical, so I also had a long road to UPT and it was worth it.
