One option to protect your miles is AwardGuard, a service offered by Frequent Flyer Services. For every year a member enrolls or renews, their membership receives a $15,000 liability. This means that any AwardGuard claims made during the membership year can be applied towards the $15,000. Should an airline go out of business, the customer should make their claim within 30 days. For further information call 800/487-8893.
