I used to work for Flyers. Even though I have a lot of affection for the good times and lessons learned, I left because I felt that there were so many things that needed to change and the CEO was a barrier to positive change. I continue to have a lot of respect for the President and the owners; I have zero respect for the CEO. I honestly believe that AF used to be an outstanding flight school, and many aspects at most of their schools remain excellent. For example, my instrument training was fantastic.
I have a passion for excellence. Many of the current managers and chief pilots that are still there do too. Some really amazing people still work there. Unfortunately, there are just a couple of bad apples that are either lazy, or are more interested in short term gain than long term excellence. That's probably why some people like Yacko have stories about getting burned by AF.
The upside? If the individual school actually trains and manages the student the way the program is designed, then the students receive excellent, expedient, deep training that is worth every penny. I agree Flyers is very expensive - but the program is awesome if implemented properly.
At most other flight schools, training is an unmanaged free-for-all. The instructors often do what is in their interest - at the expense of the student.

Whatever school you choose, make sure that you know what you are supposed to do for each certificate and rating that you work on. Know the requirements and the standards. Stay objective, stay teachable, and keep seeking advice here on this forum and from any aviation professionals that have earned your respect. Then you have a better shot of not getting milked for flight hours and tho$and$ of dollar$!!

Good luck.
