Graduate first, that's the goal. Then when you get back from 130 training, your squadron will probably want you full-time for a while. Do it. Get every flight you can. Go on every XC and local you can. The time will come if you are always willing to fly. Realistically? 8 years or so out of UPT seems to be the number as far as how long it takes to be competitive for a job at a major.
