From Feb. 1 through March 31, 2009, American AAdvantage members can earn 1,500 bonus miles for every 5,000 miles purchased through the buyAAmiles program. If you’re just short of an award ticket, this is certainly a good time to buy miles to make up the difference. Members may earn up to 12,000 bonus miles with this offer. Members may buy or give up to 40,000 miles per AAdvantage account per calendar year. Visit http://www.aa.com/buyAAmiles for details.
