Air Miles automatically deposits reward miles in a user's account 60 days after he makes an eligible purchase, while bonus miles may take as long as 120 days to appear. Eligible purchases include most made with a participating American Express or Bank of Montreal card.
In addition to offering reward miles for purchases made with certain credit cards, Air Miles offers reward miles to account holders who make purchases from participating businesses. Air Miles account holders can also purchase miles directly from Air Miles and use them to redeem rewards through the service. Air Miles assesses a $10 service fee for purchased reward miles, as of 2015. In all cases, Air Miles automatically assigns reward miles to the account holder who has made the purchase.
Air Miles provides its account holders with a reporting form for missing reward miles. If an eligible transaction does not add reward miles to the appropriate account, the account holder is responsible for contacting Air Miles and asking the company to check the status of the reward miles in question. Users with inactive accounts can reinstate their miles at a cost of $.15 per mile. Reactivated reward miles expire five years after the reactivation date.
