Search the board, lots of info here. Guard/reserves is the way to go if you're already flying for a living. 10 years from wings + 1 year of UPT + AMS/OTS and breaks in between. You're looking at 11.5-12 years total. First thing you need to do is get the AFOQT and BAT(or whatever they call it now) done. Without it, you can't get very far.
