More zip has been added to the “Delta SkyMiles Cards” from American Express. Consumer and small business cardholders can now earn more bonus miles depending on the amount of purchases made during the year. Plus, “Gold” and “Business Gold” cardholders will automatically receive a $99 domestic companion certificate upon renewal and “Platinum” and “Business Platinum” cardholders will automatically receive a complimentary domestic companion certificate upon renewal. Delta and AmEx also offer “Platinum” and “Platinum Business” cardholders the ability to earn 10,000 “Medallion Qualification Miles” from $25,000 in annual spend and an additional 10,000 “MQM” for $50,000 in annual purchases. Additionally, the program offers “Always Double Miles” on every eligible dollar they spend on Delta Air Lines purchases, as well as at supermarkets, gas stations, drugstores, home improvement stores, and more, except for “Options.” For more details on the Delta/AmEx program visit “http://www.americanexpress.com”:http://www.americanexpress.com.
