True, Delta SkyMiles aren’t the greatest in the world. But, really, what do we care? It’s free travel and we’re addicted. The Suntrust is better than most other debit cards because you get 1 mile per dollar spent. It’s no longer limited to the same handful of states. With Vanilla Reload cards/prepaid/Bluebird, it’s easy for people these days to spend lots of money and earn tons of miles.
