Just for curiosity, I looked at what we had spent for our round-trip, first class, tickets for this year's SXM trip, and how much we had earned on credit card cash back awards last year. Our cash back awards more than paid for those tickets. And since we charge those tickets to the AAdvantage Executive World Elite Master Card, we earn 4 miles for every dollar spent on those, as well as the miles for the flights. Hopefully one day, we'll acctually be able to use those miles, lol.
