Credit cards with air miles are a great way to earn air miles and redeem them for travel flights, seat upgrades, hotel discounts, and even car rentals. That's what travel hacking is all about - flying further, for less. 

What are Air Miles? 
Air miles, also known as frequent flyer miles, serve as a customer loyalty program for airline passengers. Airlines reward you with points each time fly with them, and you eventually build up enough points that you can redeem for incentives, such as free or discounted tickets or ticket upgrades. Besides, some credit cards also offer Air Miles rewards so that you can accumulate miles based on how much you spend on your credit card.

How to choose the best Air Miles Credit Card? 
The best credit card for air miles rewards would depend on your spending patterns and the benefits offered by the credit cards provider. For instance, a card may offer higher air miles points on dining spend. If you eat out frequently, that would be a good fit. Similarly, there is a wide range of categories that will earn you more air miles. These include online shopping, entertainment, petrol, golfing and overseas spend.
