Rabbit- I'll go into more detail when we chat, however, I have heard mixed reviews about ATP. Most of the people I have talked with have had good experiences, however, I find some regret it after they leave ATP and go to the regionals, and fail out of the school house because they realized, "hey...maybe 410 TT isn't really enough time to prepare me to fly jets and go through 121 ground school".
Another problem I have with ATP is that the people teaching you, are also being pushed like hell by management to leave, and get on with a regional airline. So your getting instruction, but its by a guy or gal who 3 months ago barely had his PPL, and 3 months from now, wont even be there...But that all depends on if having a personal relationship with your instructor is important to you.
Listen. I'll PM you my # and we can set up a time to chat. Theres just too much to potentially talk about, and I don't feel like typing war and peace.
