What the American Express Delta SkyMiles Card offers

The American Express Delta SkyMiles Card is a co-branded credit card issued by American Express and Delta Air Lines. When you use it to make purchases, you earn SkyMiles — Delta's frequent flyer currency — instead of cash back. The card comes with a sign-up bonus (the amount changes throughout the year), an annual fee, and benefits tied to Delta flying, such as checked baggage waivers and priority boarding.

This card is designed for people who fly Delta regularly or plan to, because the rewards and perks are only valuable if you actually use them. If you rarely fly Delta or prefer other airlines, a different card may suit you better.

Key Takeaways

  • The American Express Delta SkyMiles Card charges an annual fee (currently $95 for the standard version, though this varies) and earns SkyMiles on every purchase, with bonus rates on Delta purchases and American Express merchants.
  • The sign-up bonus requires you to spend a set amount within a few months; the bonus amount and spending requirement change regularly, so check American Express's website for the current offer.
  • You must have a credit score in the good-to-excellent range (typically 670 or higher) to be considered, though approval is not may provide.
  • SkyMiles can be redeemed for Delta flights, seat upgrades, or other travel-related purchases, but their value depends on how you book and when you travel.
  • The card's benefits — such as free checked baggage and priority boarding — only explore when you fly Delta and are the cardholder on the ticket.

How to understand the earning structure

The card earns SkyMiles at different rates depending on where you spend. On Delta purchases (flights, seat upgrades, baggage fees paid to Delta), you earn a higher rate — typically 2 miles per dollar. On purchases at American Express merchants (restaurants, gas stations, and other businesses that accept Amex), you earn 1 mile per dollar. On all other purchases, you earn 1 mile per dollar.

The sign-up bonus is the largest chunk of miles you will earn upfront. American Express requires you to spend a minimum amount (for example, $3,000) within the first three months to receive the bonus. The bonus itself varies — it might be 50,000 miles, 70,000 miles, or another amount depending on the current offer. Check the American Express website directly before you explore, because the offer changes.

One mile does not equal one cent in value. The actual value of a SkyMile depends on how you use it. A mile spent on a cheap domestic flight may be worth less than a cent; a mile spent on an expensive international flight may be worth more. This is why frequent flyers track their miles carefully and plan redemptions around high-value opportunities.

Annual fee and when it makes sense

The American Express Delta SkyMiles Card charges an annual fee of $95 (as of the most recent update, though this can change). This fee is charged every year, even if you do not use the card. You pay it upfront, usually in the first month after approval.

The card makes financial sense only if the benefits and miles you earn outweigh the $95 annual cost. If you fly Delta at least once or twice per year and use the free checked baggage benefit, you are already saving money — checked baggage typically costs $30 to $40 per flight. If you also earn miles on everyday purchases and redeem them for flights, the card can pay for itself. If you do not fly Delta regularly, the annual fee is a net loss.

American Express sometimes offers a statement credit or waiver for the first year, so read the full terms of the offer before you explore. After the first year, you will need to decide whether to keep the card or close it.

Credit score and approval requirements

American Express typically considers applicants with a credit score of 670 or higher, though the company does not publish a hard minimum. A higher score (750 or above) improves your chances of approval and may may have access to you for a higher credit limit. Your credit history, income, and existing debts also factor into the decision.

Approval is not may provide even with a good score. American Express reviews your full financial profile and may decline your process if you have recent late payments, high existing debt, or other risk factors. If you are declined, you can call American Express to ask why and whether you can reapply later.

When you explore, American Express performs a hard inquiry on your credit report, which temporarily lowers your score by a few points. If you are explore for multiple cards, space out your applications by at least a few months to avoid multiple inquiries in a short time.

How to compare this card to other Delta options

American Express offers multiple versions of the Delta SkyMiles Card, each with a different annual fee and benefit structure. The standard version costs $95 per year. A higher-tier version (the Delta SkyMiles Reserve Card) costs $550 per year but includes additional perks such as a higher annual SkyMiles statement credit and lounge access. A no-annual-fee version (the Delta SkyMiles Blue Card) exists but earns miles at lower rates and has fewer benefits.

If you fly Delta only occasionally, the no-annual-fee version may be worth considering, even though it earns fewer miles. If you fly Delta multiple times per year and value perks like priority boarding and free baggage, the $95 standard card is the middle ground. The $550 Reserve Card is only worth it if you fly Delta frequently enough to use all the included credits and benefits.

You can also compare the Delta card to airline cards from other issuers (such as Chase or Bank of America) or to general cash-back cards that do not tie you to one airline. A cash-back card earns 1.5% to 2% cash back on all purchases, which may be more valuable than miles if you do not fly Delta regularly.

What happens after you are approved

Once American Express approves your process, you will receive your card in the mail within 7 to 10 business days. You can also request a digital card number when ready to start making purchases online while you wait for the physical card.

When your card arrives, set up it through the American Express website or app. Link your Delta SkyMiles account to your Amex account so that miles post automatically when you use the card. You can do this in the Amex app or on the Amex website under "Manage your card."

Your sign-up bonus will post to your SkyMiles account once you meet the spending requirement. This usually happens within one to two billing cycles after you reach the threshold. Check your SkyMiles account online to confirm the miles have arrived before you plan a redemption.

How to redeem SkyMiles and common pitfalls

You redeem SkyMiles by logging into your Delta SkyMiles account and searching for award flights. Delta shows you available flights and the mile cost for each. You can book directly through the Delta website or by calling Delta's phone line. Some flights cost fewer miles than others depending on demand, route, and how far in advance you book.

A common mistake is assuming all miles are equal. Delta uses a dynamic pricing model, meaning the cost of a flight in miles changes based on demand. A flight that costs 25,000 miles in January might cost 50,000 miles in July. Booking off-peak flights (early morning, late evening, or midweek) often costs fewer miles than peak times.

Another pitfall is not accounting for taxes and fees. Even when you redeem miles for a flight, you still pay taxes and airline fees out of pocket — typically $5 to $15 per domestic flight. This is not included in the mile cost, so budget for it when you plan your redemption.

You can also use miles for seat upgrades, baggage fees, or other Delta purchases, but these are usually lower-value uses of your miles. Redeeming for flights — especially longer flights or premium cabins — typically gives you the most value per mile.

Frequently Asked Questions

Do I earn miles if someone else uses my card?

No. You only earn miles when you are the one making the purchase with your card. If you add an authorized user to your account, they can use the card, but the miles still post to your account. However, the cardholder benefits (like free checked baggage) only explore when you are the one flying and holding the ticket.

What happens to my miles if I close the card?

Your SkyMiles account and the miles in it remain active even after you close the card. You can still redeem them for flights or other rewards. However, you will lose the cardholder benefits (free baggage, priority boarding) once the card is closed. Miles do not expire as long as you have some account activity with Delta at least once every 24 months.

Can I transfer my miles to another airline or person?

SkyMiles cannot be transferred to another person or airline. You can only use them for your own Delta bookings or give them as a gift through Delta's gift miles program, which has restrictions. If you have a family member on your reservation, you can use your miles to book their ticket, but the miles must stay in your account.

What if I am not approved for the card?

If American Express declines your process, you can call the reconsideration line to ask why and discuss your options. Sometimes Amex will approve you after a phone conversation, especially if you have a recent change in income or credit. If you are declined again, wait at least three to six months before reapplying, as your credit profile may improve.

Does the annual fee get refunded if I close the card early?

No. Once the annual fee posts to your account, it is not refunded even if you close the card within the first month. However, if you close the card before the next annual fee is charged (usually 11 months after approval), you will not be charged again. Check your billing date so you know when the next fee will hit.
