You will need eighty hours total time prior to starting the Airline Career Pilot Program with credit for private. If a student does not have that time, they will need to purchase the extra time in advance.
I really do not understand your issue with only having one start date per month available. As I mentioned before, this is a high complex program that involves a huge amount of logistical planning. ATP cannot simply start people whenever the student feels like it. Students have to fit into the flow of ground school for CFIs, FAA check rides, etc. Furthermore, most colleges only start students twice per year. You were offered a class date that was only two months out into the future and you aren’t even ready to join the program yet anyways, I am having a hard time understanding the issue here.
