with the economy suffering and the aviation industry going into another severe slump, you should go active duty AF.
Dont listen to the stories you hear about UPT being hard. Its EASY! youre already a 121 pilot, you will breeze through the program. Youre going to want to fly heavies I presume.
Do it, its stable, and youll lay over in some of the finest Middle East tents ever built. I left active duty and joined the reserves (much better), but since your decision is time sensitive you should go active duty now and worry about getting out later
