Depends--At the end of the long(er) range goal: Do you want to work full time? Know that it may not be possible when the time comes as a pilot in an ANG unit. If not, part time? Don't know what your other career goals are so giving advice is difficult. Active duty flying has many pitfalls too. I suspect that you need to build a lot of time to compete for an airline job right? If I am correct being in the Guard or Reserve is better assuming you can fly enough and can work enough there or elsewhere to feed yourself.

In the ANG, UPT may not be possible at all either, but if so, I would think getting their "only" slot (most probably singular) easier from a unit you are already a part of.

Another possiblity is to get into ROTC and take the Active duty job/UPT. I think commitments for UPT on active duty are back to 8 years, but not sure. They might still be 10! Keep in mind too that it doesn't include UPT time of 1 year so it's really 9 or 11 years.

Trying to give you tastes of routing since I don't really have enough info to help more. Let me know...Philly
