The amount of flight time you get will depend on your platform, deployment schedule, training needs, and money. You'll get enough flight time before and after you get your wings.
As an example, during my last home cycle, I was averaging about 15-20 hours per month, some way less, but none too much more. I think my low time month was 7 or 8 hours, but there was leave thrown in there and some other things. I think my high month for the summer was about 22 or 23 hours... I'd have to look at my log book.
While deployed last year, I flew A LOT more than that... 50 to 70 hours per month. I've only done one deployment, and that Expeditionary, so I don't know how that compares to the normal boat cruise. I'm getting less flight time this deployment, but I'm in a different theatre and its a different war.
I'd also have to look at my logbook to see how that compares to flight school.
After IFS, all the time you'll log in the aircraft will be Special Crew Time. Yes, during T-6 phases, you will get to actually fly the aircraft. The first few flights, you're in the front with your IP in the back. After those flights, you sit in the back, but your IP may let you take the controls. I got to fly the T-6 quite a few times after my initial flights. Even on those flights, you won't log any pilot time... all special crew time.
