We have a Citi Bank-American Airlines credit card (see photo above) As you may have guessed, we chose it for the "miles" as our favorite destination is on the AA system.  We use it frequently enough so that the accumulated miles are not forfeited over time.  

It works for us, but I wonder...are we missing out?  Are there better deals out there?  Are we too restricted?

You're never too old to learn and we're open to suggestions.  Thanks!
