Hello, and welcome FT.

Being located on one of the coasts will definitely help. I'm a full time student, and have made plat for the last 2 years (and scheduled to make it this year). My break up is usually 16,000 miles international for ~$750, and 34,000 domestic (not sure of costs), most of which is transcontinental, and heavily uses 500 mile minimum bonuses and additional layovers to maximize mileage.
