It cost $.0125 per mile transferred when you transfer American AAdvantage miles to another member. So transferring 1,000 miles will cost $12.50.
Note that there is a $20 per transaction processing charge. Also, AAdvantage accounts less than 30 days old are not permitted to share or receive miles. Each AAdvantage member is limited to sharing or receiving, in a calendar year, a combined total of no more than two-hundred thousand (200,000) AAdvantage miles. Also note, the miles transferred with the Share Miles program do not count towards AAdvantage Gold, AAdvantage Platinum, AAdvantage Executive Platinum or AAdvantage Million MilerSM status qualification.
