I was wondering if anyone knows the statistics of people going through ATP and making it to a major airline.
Unfortunately the majority of grads ride off into the sunset and don’t check back in to let the school know of their success (or not). That’s one of the reasons ATP recently started their Alumni Association to try and track it but the short answer is no.
As Adam said, people do not often update ATP once they have left the fold. But those that do are featured on the Airlines Placement Page. You can filter results by airline there.
