Matthew,
I am anticipating on leaving for ATP in January. I'm waiting for an answer from the FAA and should know this week.
As far as attending ATP, I have done the math and the research and have come up with the same conclusion every time; you get "more" for your $ @ ATP than you would at any other flight academy, school or in my opinion...FBO. Now I'm sure there are some that will take issue with that, however, ATP is my choice.
The "more" that I'm speaking of is the amount of multi-engine time that you get for the money. Granted, I'm 45 and really don't have the luxury of time, if you will, that someone like yourself has being only 16 yrs of age. Use your time constructively & wisely. Try to avoid from dilly dallying around and stay focused and determined. Steady Eddie wins the race.
All the best. Blue skies.
