either way, your not going to get bumped up a few months... MAYBE a few weeks at best, but still not worth it. Your family will never see you at vance with their 12 hour days anyways, versus at corpus you do with your time what you want. I got in A-pool mid- june, by the time i did all my initial check in things the first few weeks, i started IFS the next week, then i had 3 weeks off between IFS and starting API, and 2 of those we were all gone during the hurricanne.
So if you wanna volunteer for AF, go for it, save another poor soul, but i dont think its really gonna save you that much time, especially with the AF 12 hour workdays.
