Delta Amex credit card increased offersAmex Delta credit cards give you the ability to use Delta miles in a way that non-cardholders can't.
However, Insider estimates that Delta miles are worth 1.1 cents each, on average, when booking award flights.
And if you know the best ways to use Delta miles, you can get significantly more value.
The card's main draw is the ability to earn Delta miles on every purchase: 2x miles on Delta purchases, at restaurants worldwide, and on takeout and delivery in the US, and 1 mile per dollar on everything else.
That's double the miles of the previous card bonus, which was 50,000 bonus miles and 10,000 MQMs after meeting minimum spending requirements.
