What the Delta American Express card is and who it's for

The Delta American Express card is a co-branded credit card issued by American Express and Delta Air Lines. It's designed for people who fly Delta regularly or want to earn rewards on everyday purchases that convert to Delta miles. Unlike a standard cash-back card, every dollar you spend earns miles toward free flights, seat upgrades, and other Delta benefits — but the card charges an annual fee and the value of those miles depends on how you use them.

This card makes sense if you fly Delta at least a few times a year and would use the miles before they expire. It's less useful if you rarely fly, prefer other airlines, or want straightforward cash rewards instead of miles.

Key Takeaways

  • The Delta American Express card charges an annual fee (the amount varies by card tier) and earns miles on purchases, but those miles are only valuable if you actually book Delta flights.
  • You earn a sign-up bonus of miles after you spend a certain amount in the first few months, but this bonus only pays off if you plan to use the miles.
  • The card offers perks like checked baggage waivers and priority boarding, which save money only if you would otherwise pay for those services.
  • Miles expire after three years of account inactivity, so you need to use the card or take a Delta flight regularly to keep them.
  • American Express requires you to pay your full statement balance each month — you cannot carry a balance like you can with most other credit cards.

How much the card costs and what you get for that cost

The Delta American Express card comes in several versions, each with a different annual fee. The basic version charges an annual fee (the exact amount changes periodically, so check American Express directly for the current figure). Higher-tier versions cost more but include additional perks like extra miles, higher statement credits, and lounge access.

The card pays for itself only if you use the perks and miles regularly. For example, if the annual fee is $95 and you earn a checked baggage waiver worth $30 per round trip, you need to take at least four round trips per year to break even on the fee alone. Add in the miles you earn on everyday spending, and the math often works — but only if those miles actually become flights you take.

When you first open the card, American Express offers a sign-up bonus: a large number of miles if you spend a certain amount within the first few months. This bonus is the biggest when ready value, but it only matters if you plan to use those miles. If you earn 70,000 miles and never book a flight, the bonus is worthless.

How you earn miles and what they're worth

You earn miles in two ways: on purchases you make with the card, and on flights you book directly with Delta. The earning rate varies by card tier and by what you're buying. For example, you might earn 2 miles per dollar on Delta purchases and 1 mile per dollar on everything else. Some categories like restaurants or gas stations offer bonus earning rates on certain card tiers.

The value of a mile is not fixed. One mile might be worth less than one cent on a short domestic flight or more than one cent on a long international flight, depending on demand and availability. This is why miles-based cards are harder to evaluate than cash-back cards: you can't straightforward multiply miles earned by a fixed dollar value. A 70,000-mile sign-up bonus might be worth $700 on one flight and $500 on another.

You redeem miles by booking flights on Delta's website or by calling Delta directly. You can also use miles for seat upgrades, checked baggage fees, or other Delta services, though these redemptions often give you less value per mile than booking a full flight.

The perks that come with the card

Beyond miles, the Delta American Express card includes several benefits. Most versions waive the first checked baggage fee on Delta flights, which saves $30 to $40 per round trip if you check a bag. The card also gives you priority boarding, which means you board earlier and can find overhead bin space more easily.

Higher-tier versions include access to Delta Sky Club lounges, where you can eat, drink, and work in a quieter space before your flight. Some versions also offer a statement credit toward a Delta purchase each year, which can offset part of the annual fee if you use it.

These perks have real value only if you use them. If you never check bags and don't care about boarding order, the baggage waiver and priority boarding mean nothing to you. If you fly once a year, the lounge access sits unused. Read the specific benefits for the card tier you're considering and honestly assess which ones you'd actually use.

How American Express works differently from other credit cards

American Express cards require you to pay your full statement balance each month. You cannot carry a balance and pay interest like you can with Visa or Mastercard. This means if you charge $2,000 to the card, you must pay the full $2,000 by the due date — you cannot pay $500 and owe interest on the rest.

This is both an advantage and a constraint. The advantage is that you cannot accidentally rack up high-interest debt. The constraint is that you need enough cash flow to pay the full balance monthly. If you're used to carrying a balance on other cards, the Delta American Express card won't work for you.

American Express also has stricter approval standards than Visa or Mastercard issuers. You typically need a good credit score (usually 670 or higher) and a solid income history to be approved.

When the Delta card makes financial sense

The card is worth the annual fee if all of these are true: you fly Delta at least three or four times per year, you pay your full balance monthly without exception, you have a good credit score, and you're comfortable with the fact that miles are worth different amounts depending on when and where you fly.

The card is not worth it if you fly infrequently, prefer other airlines, want to carry a balance, or would rather have straightforward cash rewards. In those cases, a standard cash-back card from Visa or Mastercard will serve you better.

If you're on the fence, calculate your actual Delta spending for the past year. How many flights did you take? How much would the baggage waiver have saved? How much would you have earned in miles, and what would those miles have been worth? If the math doesn't clearly favor the card, skip it.

What happens to your miles and account

Delta miles expire three years after your last account activity. Activity includes taking a Delta flight, redeeming miles, or even just earning miles on a purchase. If you don't fly Delta or use the card for three years, your miles vanish. This is why the card only makes sense if you plan to use it regularly.

If you close the card, your miles remain in your Delta SkyMiles account as long as you have account activity elsewhere. But if you close the card and don't fly Delta or earn miles any other way, your miles will eventually expire. Some people keep the card open just to maintain their miles balance, which means paying the annual fee even if they're not actively using the card.

Frequently Asked Questions

Can I use Delta miles on other airlines?

No. Delta miles can only be redeemed on Delta flights or Delta-related services like baggage fees and seat upgrades. You cannot transfer them to other airlines or use them for non-travel purchases. This is why the card only works if you actually want to fly Delta.

What's the difference between the different Delta American Express cards?

Delta offers several versions at different annual fee levels. The basic version has the lowest fee and basic perks. Higher tiers cost more but include extra miles, statement credits, lounge access, and other benefits. Choose the tier based on how much you fly and which perks you'd actually use.

Do I need good credit to get approved?

American Express typically requires a credit score of 670 or higher and a solid income history. If your score is lower or your income is unstable, you may be denied. You can check your credit score for free through many banks and credit card issuers before you explore.

What if I don't spend enough to earn the sign-up bonus?

You won't receive the bonus miles. The bonus is only paid once you hit the spending threshold within the time window. If you can't reach that spending naturally, don't open the card just to chase the bonus — the annual fee will cost you more than the bonus is worth.

Can I use the card for business purchases?

American Express offers separate business versions of the Delta card. If you own a business and want to earn miles on business expenses, ask about the business version. Personal and business versions have separate accounts and separate annual fees.
