Ya I agree with the above posts as a "retired" to airlines CFI. The biggest problem with part timers is many of them take alot more hours of training due to the fact that they have less scheduled flight with longer time in between flights. Even if this works for you, you have less flights per week meaning a cancellation or some weather may cancel you straight out for an entire week or longer. My .02 cents was always to try and just save as much as you can, then do your flight training in a manner so that you could fly about 3-4 times a week. Good luck its a blast!
