Join the Air Miles Reward Program, if you live in the United Kingdom, Canada, Spain or The Netherlands. The program is not available to U.S. residents. When you sign up for the program on the company's website, you will be given a collector number that you will use during future purchases.
Apply for an American Express credit card through the Air Miles program. This is a good way to double up on your Air Miles; you earn some miles for using your card, and then more miles for making purchases through partnering businesses.
Use the Air Miles website to search for businesses that partner with Air Miles. Some of the businesses include Apple, Old Navy, Barnes and Noble, Babies R Us, Expedia and many more. If you find a product you are interested in purchasing, enter in your collector number during the purchasing process. You will earn an air miles credit for the purchase.
Keep track of bonus mile offers on the Air Miles website. The company often has special offers that give you extra miles for specific products. You can find these by going to the "Offers" page of the Air Miles website. Depending on the purchase, you can often earn thousands of extra air miles.
