I'm considering ATP as well. I would likely either attend Denver or Ogden if I decide on ATP. I would go in with a private as I am almost finished. I have talked to a few different people at ATP and they say they do "guarantee" a CFI job. One told me they no longer make you answer phones waiting for a CFI job to open up. You may not get your desired location as a CFI. It seems like there is so much negativity towards ATP. However, two experienced airline pilots and my CFI (retired) recommend that I go to ATP to complete my ratings and be a CFI with ATP.
I fall in the career change category. I have a bachelors degree and was in law enforcement for about 15 years. Soon to be 40.
ATP sounds nice but I'm still unsure at this point.
