Since only the army guy actually provided a suggestion to our Young Grasshopper, look into consulting firms, like accenture, kmpg, deloitte, etc. Many of their young people travel every week. It is not glamorous. I have had friends traveling to the same second or third tier city for months on end, but the points and miles rack up. If you do that on top of the CC bonuses and other things that are suggested throughout this blog, it will get you pretty far. The consulting firms also hire young folks right out of college. Good luck.
