One of the easiest ways to earn frequent flier miles is to enroll in one of the “dining for miles” programs. United, Delta and American Airlines all have “dining for miles” programs. The beauty of these programs is that you don’t have to show a card or coupon to get credit. All you do is register your credit card with program and it automatically detects each time you use the card at participating restaurants. In my area, many of the most popular restaurants participate. With American Airlines program you can earn up to 10 miles per dollar spent (off the total bill). This can really add up because you can use any credit card (even those earning miles).

One note : these programs are administered by the same company, www.rewardsnetwork.com, so you can’t register the same card for all three programs.
