In association with American Express, SkyMiles members will earn double miles on all purchases made using the Delta SkyMiles Credit Card from Oct. 15 to Nov. 30. Normally, members earn double miles when they use their card at supermarkets, home improvement stores, drug stores, gas stations, the U.S. Postal Service and when they use it to pay for wireless phone bills and Delta Air Lines tickets. During the promotion period, however, all purchase transactions qualify for the double miles bonus.

Bonus SkyMiles earned as part of this promotion are limited to 25,000 miles and balance transfers and express cash transactions are excluded.
