Keep in mind that time is a major factor in waiver considerations. The more time you have with good behavior and honorable service, the less of an impact your "dumb kid days" will have on your package.
If the AF won't take you now, apply to another branch and then transfer later.
If you can find a recruiter that is willing to at least attempt that OTS package for you, then you could feasibly run both packages (enlistment + OTS) at the same time. If you don't get picked up after a board or two, then head off to BMT at cheery JBSA-Lackland. There are a lot of really cool enlisted jobs that also offer bonuses, and you will also pick up E-3 right out of the gate due to your degree. You can also knock out your Master's with tuition assistance over the following 3-4 years.
However, understand that the AF generally only allows one commissioning attempt per lifetime. The waiver allows you a second chance, but if you get it, that's it, kid.
If you get that waiver to commission, you got to make it happen-- don't even consider dropping out of OTS or waffling out last-minute.
It's been some time since I went through OTS, but the fundamentals are still the same, and there are a certain number of new cadets that inexplicably drop out each year after a couple of weeks. For those that understand the amount of effort that goes into a successful OTS application, it's absolutely baffling why one would go that far just to quit after two weeks of a generally unpleasant but wholly survivable experience.
Again, good luck. I hope it works out.
Stay away from the jobs requiring a TS for now
