From what recruiting has told me they want you to interview 2 to 3 months prior so you can get into a class when you have completed the time. You said you expect to be at 1400 in November will it take you another 2 to 3 months to get the remaining 100 hours? I guess the reasoning is your class date will be 2 to 3 months after you interview.

Really you only need 1475 hours when you start training as between ATP CTP and training for either CRJ or ERJ you will get the remaining 25 hours there.
