Double Miles on Delta and Northwest Through End of Year for Co-branded Amex Cardholders

Delta and Northwest are offering double miles on all flights through the end of the year for Delta Amex cardholders. Registration is required no later than September 30.

There’s no limit to the bonus, and you don’t have to buy your tickets with the card. Travel date is what’s relevant, the bonus applies to tickets purchased earlier in the year provided that you register and travel during the July 1 through December 31 promotion period.

  1. Very Nice! I also got an e-mail last week where I get 10k additional miles for every flight flown up to 100k. I think that’s a targeted promotion though.
    That basically means every flight to California I will be getting 25k+ miles. Well worth it to me.
