Where do you live? In most cities of reasonable size in the US, AAdvantage Dining may be the most reliable way. It works with any credit or debit card that you already have. (AAdvantage Shopping works from "everywhere", but not all shopping purchases reliably post AA miles, plus even when they do it can take forever and lots of followup.)
