Congrats and welcom!
After almost 10 years of active duty AF one thing I would strongly recommend is for you to look very close into the Air Guard. A few of my bodies, all pilots, started in maintenance and had an advantage into becoming AF pilots in their Guard unit. The Guard is more a family and very close net than active duty. If I were to do it all over again I will definitely go Guard. In addition, many Guard units can waive the degree and providing you are with in a year from completing your college degree you could be selected for AMS and onto UPT. Having your pilot ratings makes you very competitive and you will definitely have an opportunity for being interview by a board.
If you are thinking active duty your sole job is AF, nothing else. And unless you have a 0700 - 1700 job schedule (Admin) it will at the very least take the first 2 years working on being qualify to do your job. This is one info the recruiters won’t tell you. The AF policy is for you as an enlisted to be able to get the 100% tuition free you have to get your supervisor's approval. So technically after BTC, tech school, OJT and obtaining your 5 level, which typically make you qualified in your field, it can take about half of your first enlistment. And as I mentioned AF comes first. So by this time you have not even started on your college education. On top of all these, you have to consider deployments. And believe me, it is not common that supervisors will not approve tuition assistance because if they do and you get deployed they have to explain the reasons why you had to drop your courses. After all that fiasco, it may very well take you two enlistments to get your degree and as it was mentioned before, you will sacrifice a lot and will have to be very discipline to put your education first. To get selected for OTS following an UPT slot in active duty, well good luck. Not to sound negative but I saw so many well qualified folks, troops that were consider superb airmen on-and-off duty and unfortunately leadership overlooked their potential and were not selected. Most of them worked their best for 2 enlistments and at the end separated due to the disappointment. I am not saying this will be the case with you but at the same time I am not going to paint a pretty picture of the system. Again recruiters will not tell you this.
Also, consider your age. Let’s say you are 20. Considering it will take 2 enlistments to complete your degree and even if it takes you 6 years to do so, you will be about 26-27. You at this point have about 3 years to be selected for a pilot slot. Once you turn 30, you are done! for UPT.
In the Guard, considering our current state as a nation at war, you will most probably be activated, however, if not activated your time will be sole concentrated on getting your college degree. You mentioned one of your interests to join was college money, well as it was mentioned most states have great deals with money for college and even paying some of your old student loans, depending on the career field. Again, I will not disregard the Guard and at the very leas do your self a favor and talk to a Guard recruiter to explore those opportunities as well.
If you are set for active duty I will also recommend calling your college AFROTC and obtaining information and my advice will be for you to get your college degree first and join your college AFROTC. Currently most folks that work hard both academically and ROTC training will almost have a chance to be selected for a pilot slot out of college. If you are set to shine an do above an beyond, your ROTC commander will definitely see your potential. As an active duty airmen, your recommendations initially come from your supervisors. By the time your commander is presented with your paper work, your name in paper has passed down so many desk, from the enlisted side. Well, you can only imagine the long process.
Lastly, depending on how hard you work on your degree you can be done in 4 years or less if you already have some college credits.
Ultimately you will make your own decision. I wish you luck on your endeavors.
Happy Holidays
