Delta SkyMiles Blue American Express

The Delta SkyMiles Blue is the no-annual-fee entry point to Delta's program, earning 2 miles per dollar on Delta purchases and at restaurants, with no foreign transaction fee. It also gives 20% back as a statement credit on eligible Delta in-flight food and beverage purchases. The catch is that it lacks the travel perks that make airline cards worth carrying, and everything outside Delta and dining earns just 1 mile per dollar. The 10,000-mile bonus after $1,000 in spend within 6 months is small. It suits occasional Delta flyers who want to earn miles without paying a fee, but frequent flyers will get more from a card with real flying benefits.
