Tanker Driver pretty much hit it on the head.

Another thing to consider is if you want to just fly or get into the "well rounded" officer mentality that ususally means a staff tour, deployment and other non-flying duties that will get in the way of being a pilot. The Guard and Reserves are a much better way to go if you want to get more flying experience and less "leadership opportunities" in that you usually have more control over your life, unless your unit gets activated.

I'm getting ready to retire after 24 years of combined enlisted, academy cadet and officer life and can tell you that if you do go active duty, your promotion will depend on many factors other than how good a pilot you are. If you just want to do a "touch and go" with the AF and get training and flying experience while in pursuit of a civilian job, I think you should stay away from the active duty ranks and go Guard/Reserve, you'll have a much better chance of being a "line swine" pilot (like I wish I was ).

Either way though, it's not a bad way to go, just make sure you go in with your eyes open and ask a LOT of questions before you sign on the dotted line.

Good Luck to you.
