As the Executor of an estate for someone with AAdvantage miles I contacted Customer Service by phone and explained that I wanted to transfer the miles to one of the beneficiaries. Within 10 minutes i received an email with the Affidavit Form and instructions. I completed the form then scanned the form and death certificate to Custom Service as requested. This all happened on Friday. The following Tuesday the miles were transferred. Talk about service and ease. Just furnishing this as one anecdotal occurrence.
