The American Express Delta SkyMiles Blue American Express Card is a no annual fee airline credit card designed for occasional flyers of Delta Air Lines who want to earn SkyMiles without committing to a premium travel card. Ideal for budget-conscious travelers and beginners building airline loyalty, this card offers 20% back on Delta in-flight purchases, no foreign transaction fees, and no fee for additional cardholders—making it a simple, low-cost option for earning miles on everyday spending. While most purchases earn just 1x miles, cardholders still receive valuable protections such as purchase protection and extended warranty coverage (up to $10,000 per item and $50,000 per calendar year), along with car rental loss and damage insurance. The Delta SkyMiles Blue American Express Card is best suited for infrequent Delta travelers who want a straightforward way to earn rewards and enjoy basic travel perks without paying an annual fee.
