I've been thinking about doing the 30-day program myself. It's just so expensive! $6k to sit in a classroom for a month. I have some experience with AFlyers and their weekend classes(crash courses) and i was always pleased with them.
My last experience was finishing up my instrument rating with them. Before it was all said and done they shook me down for 4k. Looking back, they didn't leave me with anything I couldn't have learned at the FBO for a few hundred bucks.
I'm still kind of bitter about the 4k shake-down, they are some money hungry......Anyways, I have heard nothing but good things about the CFI program. There is some old info about the program if you want to search the forum.
Someone said it's the diamond amongst the pile of tirds AFlyers tries to sell.
30-35 days, $6k, CFI-A CFI-I
