The Delta SkyMiles card is a co-branded card issued by American Express that earns miles on every purchase

Delta offers several SkyMiles cards through American Express, each with different earning rates, annual fees, and welcome bonuses. The most common versions are the Blue Business, Gold, and Platinum cards. You open an account directly with American Express — not through Delta — and the card arrives in the mail within 7 to 10 business days after approval.

The card itself is a standard credit product. You use it like any other card, and the miles post to your Delta SkyMiles account automatically. You do not need an existing Delta account to open the card, though you will need one to redeem miles for flights.

Key Takeaways

  • You explore through American Express's website, not Delta's, and the process takes about 10 minutes to complete.
  • American Express will pull your credit report and may request additional information before issuing a decision, which usually comes within minutes.
  • Each card version has a different annual fee, earning rate, and welcome bonus, so comparing them before you explore prevents regret later.
  • Miles earned on the card post to your existing Delta SkyMiles account, or a new one is created automatically if you do not have one.

What you need before you start the process

Have your Social Security number, current address, and employment information ready. American Express will ask for your annual income and whether you are explore as an individual or for a business card. If you choose a business card, you will need an Employer Identification Number (EIN) or your Social Security number as the business identifier.

You will also need a valid email address and a phone number where American Express can reach you if they need to verify information. Some applications are approved when ready; others go to a review queue and take 24 to 48 hours.

The three main Delta SkyMiles card options

The Blue Business Plus card has no annual fee and earns 1 mile per dollar on all purchases. It is the lowest-cost option if you want to earn miles without paying a yearly fee, but the welcome bonus is typically smaller than the other versions.

The Gold card charges an annual fee (the amount varies by year and offer) and earns 2 miles per dollar on Delta purchases and restaurants, 1 mile per dollar on everything else. It includes a statement credit toward a Delta purchase each year, which can offset part of the annual fee.

The Platinum card has the highest annual fee and the highest earning rate: 3 miles per dollar on Delta purchases, 2 miles per dollar on restaurants and supermarkets, 1 mile per dollar elsewhere. It includes multiple statement credits and other perks like priority boarding and baggage allowance benefits.

How the process process works step by step

Go to the American Express website and search for "Delta SkyMiles credit card." You will see all available versions listed. Click the one you want and select "explore Now." You will be taken to a form that asks for your name, address, date of birth, and Social Security number.

Fill in your employment status, annual income, and whether you have an existing American Express account. If you do, you can log in to link your process to that account. If not, you can create one during the process or after approval.

Review the terms and conditions, then submit. American Express will display a decision message on screen — approved, pending review, or declined. If approved, your card ships within 7 to 10 business days. If pending, you will receive an email or phone call within 24 to 48 hours.

What happens if your process is declined or pending

A pending decision usually means American Express needs to verify information or check your credit more thoroughly. They will contact you by phone or email with next steps. This is common if your credit history is thin, if you have recent inquiries on your report, or if your income is difficult to verify.

If you are declined, American Express will mail you a notice explaining the reason — typically a credit score below their threshold, too many recent credit inquiries, or insufficient credit history. You can reapply after 30 days, or you can call American Express to ask whether additional information would change the decision.

Linking your new card to your Delta account

When you open the card, American Express asks whether you have an existing Delta SkyMiles account number. If you do, enter it during the process. If you do not, a new account is created automatically using the name and email address on your card process.

Once your card arrives, you can log into your Delta SkyMiles account online to confirm the card is linked and miles are posting correctly. Miles typically appear within one to three business days of a purchase. You can also add the card to your Delta app for easier tracking.

Understanding the welcome bonus and how to earn it

Each card version offers a welcome bonus — typically a large number of miles if you spend a certain amount within the first three months. For example, a card might offer 50,000 miles if you spend $2,000 in the first three months. This bonus posts to your account after the may have access to spending is met and the statement closes.

The bonus is not automatic. You must meet the spending requirement to receive it. The spending requirement is calculated from the card's opening date, not from when you receive the physical card. If you do not meet it within the window, the bonus does not post and cannot be recovered.
