Most people are unaware of the fact that shopping online can help you earn valuable points on both your credit card and selected reward program. The process is simple: log in to your airline's frequent flier account, go to the mall, and start shopping! Most major airlines have over 600 retailers from which you can earn miles. In some cases, you may qualify for free shipping if you spend over $50. Depending on which retailer you select, you can earn more than 4 times the dollar amount spent in reward points.
To the point - Point 8 :
Shop online as frequently as possible through your desired airline's website so you may receive credit for your purchases.
