My top five reasons why iDine is one of the best ways to earn FF miles without flying:

5. I can register 5 different credit cards with 5 different airline's iDine program, and be able to add miles to each program at-will.

4. If I pay with a mileage-earning credit card, I get an additional mile/$.

3. If I register different cards with different programs, I can earn at the same restaurant twice in one month.

2. If I am Exec Plat with AA, I get a 500 mile bonus if I eat at three different places within a month.

1. I just earned 2,000 miles for dinner at a new restaurant downtown, and didn't even realize it at the time!
