In the battle of Delta vs. JetBlue, Delta's the clear winner. Sure JetBlue has lower fees, but credit card selection and redemption options put Delta ahead.
Review: Is the Delta Reserve credit card the best card for you?
American Express issues seven personal and small-business Delta credit cards to suit every type of traveler. The Delta SkyMiles® Reserve American Express Card is the most premium of the personal cards and currently offers a substantial welcome bonus: Earn 80,000 bonus miles and 20,000 MQMs after you spend $5,000 in purchases in the first 3 months from account opening.
You ll earn 3x miles on Delta purchases, but just 1 mile per dollar on everything else there are no other bonus categories. If your objective is to earn more Delta miles on your everyday spending, you ll want to look at other Delta cards or cards that earn American Express Membership Rewards points like the American Express® Gold Card
