Travel Behavior - It is also very important to examine your travel behavior when trying to find the best credit card with airline miles. For example, if you tend to fly, especially on one particular airline, many times per year, these cards can certainly pay off. Infrequent travelers, however, may find the cost of the card does not make up for the reward.
Some cards also offer distinct features such as free companion airfare, or free cabin upgrades. If you have specific criteria when traveling, make sure to find a card that caters to these needs.
Spending Habits - You should also be aware that your spending habits can factor into which type of airline reward card you choose. Some of the best airline miles credit card offers issue points for every purchase you make using the card. Others issue points for certain purchases, or only at certain locations.
You should always make sure your spending habits will match the requirements of the card in order to ensure you get the very most benefit. Also, make sure there are no restrictions on the number of points you can accumulate each year, as this could end up costing more money in the long run.
