Best Airline Miles Card

I do not understand how it works. I know some companies have restrictions on airline miles. Can someone tell me the experience of the credit card is best to use. I want a company that gives the best deal on their airline miles and / or is flexible on their miles (where you can travel, etc..). Thank you.

If you're only going for miles and live near an airport hub, it would be preferable to obtain a card offered by an airline. They often have special offers, for example, I think America still have their offer of 30,000 miles after the first $ 250 spent, a mile for every $ 1 thereafter, and a bonus of 20,000 after the first year.
