This will vary depending on the type of credit card you have, as well as your credit limit. As an example, you can earn around 3,000 Air Miles, plus any additional bonus Air Miles reward miles you receive, each year if you have a credit limit of $5,000 per month. You can likely fly from Vancouver to Toronto with around 3,600 miles. As another example, for Air Miles World Elite cardholders who have a monthly credit limit of $10,000, you can earn up to 12,000 miles a year, plus any bonus miles. With this amount, you could fly from Calgary to Sydney, Australia, and still have miles left over.
