I have to disagree. At AF the clock starts on your account the moment you walk in the door. If you are there for 2 hours but only did 1.5 ground guess what you get charged. This is how it was in DFW at least. I would not suggest them in any way. I hated the CFI course there. Cost me more than double the qoute, and I wasn't out of practice or anything. I did my first flight for my CFI with an instructor there and he said he would sign me off. Two weeks later when I had my checkride he went back on his word because "AF policy is that signoffs are no longer valid after 2 weeks!!!" What about 90 days as issued by the FAA. It is just another way for them to get your money. New instructor everyday, and half the time the instructor had just gotten his license. On more than one occasion we ended up teaching the instructor a thing or two. As for all the ground school, well that just means there will be an instructor somewhere in the building for you in case you need him. We got about 20 hours of instruction, and spent the other 100 teaching eachother lesson plans over and over. GO SOMEWHERE ELSE!!!! PLEASE, unless you have about 7 grand and two months, don't take the 3 grand 30 day course at AF.
