Good article and quite interesting. However, I notice that Randy didn't mention the mileage caps that many of these cards have. I did find one that, for small business owners (or the self-employed among us) has a higher cap. The Citibank AAdvantage Business Card has a cap of 150,000 miles a year, as opposed to the 60-100K that most have. It's a pretty good deal. My good friend who has a business loves it. The application number is 1-888-66-APPLY and offers 7,500 miles as a sign-up incentive.

I wish I were 1,000 miles away
