American AAdvantage has introduced a new way for AAdvantage members to share their expert tips about the program at the airline’s Facebook page. The Tips Tab debuted on AAdvantage’s Facebook page last month and the program invites members to share their advice and wisdom about earning and redeeming AAdvantage miles with other members. You are also welcome to post your advice about reaching elite status and program benefits. You can view tips and rate tips posted by other members at http://www.facebook.com/aadvantage – A few top tips from members include purchasing Groupon deals through the eShopping mall to earn eight miles per dollar and checking out aa.com/offers frequently to see the latest offers from the program.
