Earning frequent flier miles can be a great way to get free or cheap plane tickets to fly anywhere you want in the world, and I’ve got a great tip that will earn you miles without flying all over the place. When you are shopping for things you were going to buy anyway, do it through an airline's website. Many airlines link to a huge variety of stores, including Barnes and Noble, Land's End, and Staples. Shopping through the airline's link can actually earn you as much as ten miles per dollar you spend. Just buy things you would have purchased anyway in a store or by directly going to the store's website through an airline link, and start earning frequent flier miles immediately. It's good for the airline, it's good for the store, and it's great for you.
