A.A.E. stands for Accredited Airport Executive. You can only achieve that title by writing and defending a report, and taking a written and oral test. Once you have completed those requirements and passed everything you receive your A.A.E. Its a pretty prestigous title to have working in the Airport side of aviation.
I believe that members of AAAE who take the test and pass can use C.M. after there name, which I think stands for certified member. You can check out there site at www.aaae.com
