The nice part about going to an FBO (Like California Airways) is you can do your training as fast (or as slow) as you would like. They say a typical full time student could take a year. If you flew twice a day like you would at ATP, you could finish your licenses/ratings at California Airways in 90 days too. It is all in your pace. ATP doesn't have this magic training program. They just fly you hard and fly you often. You could do the same thing at any FBO.
I really hope you decide against ATP. It is the exact same training you can get anywhere else but for the bargain price of an extra $20,000 over any other school. Oh well, if you have all that extra money, it is yours to spend!!
