Best Credit Card (US) for Mileage Hounds

"Why love only one when you can love many", a billboard for polygym read outside of Salt Lake City on a recent trip I took. Good advice in some instances. The Starwood American Express is the best for mileage hounds. You can earn points in the Starwood preferred guest program which can be transfered on a 1:1 basis to most major US and International Airline programs so your not tied to any one airlines program. Perfect when planning your next trip to Utah.
