Through December 31, 2003, American Airlines offers platinum Mastercards for individuals and for businesses that have no annual fee for the first six months and give 10,000 miles with first purchase, plus other goodies. After the free six months the fees for the individual and business cards are $85 and $75 per year, respectively.
