R U talking about All ATPs? If so, I just got my ATP certificate through their 2-day course in the Piper Seminole. Instructor had a great attitude and was pretty smart.....but very young/inexperienced (350TT). It was a big boy prgm....study the aircraft systems b4 you go, 2-flts and grnd training on day 1. Check on day 2.
I passed, but had a terrible Designated Pilot Examiner, so if you go to Addison, Tx, hit me up n I'll give u the name to avoid...although ATP told me they would never use him again after I blasted an email to the company leadership.
