I'm a senior in high school living on the east coast about to attend college on the west coast and I'd like to find the best program for my situation. I'll probably be flying round trip from San Francisco to Dulles (or another airport if its cheaper) at least 4 times each year for the next four years in economy. I noticed virgin america typically has the cheapest flights, but their program is rated poorly. What would be the ideal program?

Also, I'm trying to establish residency in California for tuition purposes and I'll need a new bank account; which bank and which credit cards would benefit me most? My expenses will mostly be food, books, entertainment, etc....

Thanks in advance
