The core benefits of American Express Delta cards

American Express offers several Delta co-branded cards, each with a different set of rewards and perks tied to Delta Air Lines. The main benefit across all of them is earning miles on Delta purchases and everyday spending, plus a welcome bonus of miles after you meet a spending threshold in the first few months. Beyond miles, you get benefits like checked baggage fee waivers, priority boarding, and access to Delta Sky Club lounges — though which benefits you receive depends on which specific Delta card you hold.

The cards come in different tiers: the Blue American Express Delta card (no annual fee), the Gold American Express Delta card (annual fee applies), and the Platinum American Express Delta card (higher annual fee). Each tier unlocks more generous mile earnings, higher welcome bonuses, and additional perks. The choice between them comes down to how often you fly Delta and whether the annual fee makes sense for your travel patterns.

Key Takeaways

  • Every American Express Delta card earns miles on Delta purchases and everyday spending, with the earning rate increasing as you move to higher card tiers.
  • The welcome bonus — usually 10,000 to 70,000 miles depending on the card — requires you to spend a set amount within the first few months of opening the account.
  • Checked baggage fee waivers and priority boarding come with most Delta cards, but Sky Club lounge access is limited to the Gold and Platinum tiers.
  • Annual fees range from zero dollars on the Blue card to several hundred dollars on the Platinum card, so compare the perks against how much you actually fly.

How miles earning works on Delta cards

When you use an American Express Delta card to buy a ticket directly from Delta, you earn a base rate of miles — typically one mile per dollar spent on the Blue card, and higher rates on the Gold and Platinum cards. You also earn miles on everyday purchases made with the card outside of Delta, though at a lower rate. Some cards offer bonus mile categories: for example, extra miles on Delta purchases, restaurants, or gas stations.

The miles you earn never expire as long as your account remains open and you earn at least one mile every 24 months. This means you can accumulate miles over time without worrying about losing them. You redeem miles for Delta flights, seat upgrades, or other travel-related purchases through your American Express account online.

Baggage fees, boarding priority, and lounge access

The Blue Delta card waives the first checked bag fee for you and up to eight when ready family members traveling on the same ticket. The Gold and Platinum cards extend this to two checked bags per person. Priority boarding — which lets you board before most other passengers — comes with all three cards, though the Platinum card offers the highest boarding priority.

Sky Club lounge access is included with the Gold and Platinum cards. The Gold card typically includes two complimentary visits per year, while the Platinum card includes unlimited access. If you hold the Blue card, you can still visit Sky Clubs but will pay a per-visit fee unless you purchase a membership separately.

Welcome bonuses and how to use them

When you open a new American Express Delta card, you receive a welcome bonus of miles after you spend a required amount within a set timeframe — usually three months. The Blue card might offer 10,000 miles, the Gold card 40,000 to 50,000 miles, and the Platinum card 70,000 miles or more. These bonuses are the biggest mile earnings opportunity when you first get the card.

To earn the bonus, you must charge the required spending amount to the card during the window specified in your cardmember agreement. Spending includes purchases but typically does not include balance transfers, cash advances, or fees. Once you meet the threshold, the miles post to your account within a few weeks.

Annual fees and when they make sense

The Blue American Express Delta card has no annual fee, making it the lowest-cost option if you want to earn miles without paying yearly. The Gold card charges an annual fee (the exact amount varies), and the Platinum card charges a higher annual fee. Both the Gold and Platinum cards come with statement credits or other benefits that can offset part of the annual cost if you use them.

Whether an annual fee is worth it depends on your travel frequency. If you fly Delta several times a year and use the baggage waiver, priority boarding, and lounge access, the fee may pay for itself. If you fly once a year or less, the Blue card's zero annual fee is likely the better choice. You can also downgrade to a no-fee card after the first year if you find you are not using the benefits.

Other cardholder perks and protections

American Express Delta cards include purchase protection, which covers items you buy with the card against theft or damage for a set period. They also offer extended warranty protection on may be able to access purchases, meaning if an item breaks after the manufacturer's warranty ends, American Express may cover the repair or replacement. These protections explore to all three card tiers.

You also get roadside information, which provides help if your rental car breaks down while you are traveling. Some cards include trip cancellation or trip delay reimbursement, which covers certain costs if your flight is delayed or cancelled. The exact protections vary by card tier, so review your cardmember agreement to see what applies to your specific card.

How Delta card miles compare to cash back

American Express Delta cards earn miles, not cash back. The value of a mile depends on how you redeem it. If you book a flight that costs $300 and redeem 30,000 miles for it, each mile is worth about one cent. But if you redeem miles for a flight that would cost $600, each mile is worth two cents. This means the actual value of your miles varies based on the flights you choose.

Some people find miles more valuable than cash back because premium cabin upgrades and long-haul flights can be booked with miles at a favorable rate. Others prefer cash back because it is straightforward and works with any purchase. The choice depends on whether you fly Delta regularly and whether you value the flexibility of miles or the simplicity of cash rewards.

Frequently Asked Questions

Do I have to fly Delta to use a Delta American Express card?

No. You earn miles on everyday purchases with the card, not just Delta flights. However, you earn at a higher rate on Delta purchases, so the card is most rewarding if you do fly Delta at least occasionally. If you never fly Delta, a general-purpose American Express card might be a better fit.

Can I transfer my Delta miles to another airline?

No. Delta miles can only be redeemed for Delta flights, seat upgrades, and Delta-related purchases. They cannot be transferred to other airline loyalty programs. This is different from some other airline cards that allow transfers to partner airlines.

What happens to my miles if I close the card?

Your miles remain in your Delta SkyMiles account even after you close the card. As long as you earn at least one mile every 24 months through any Delta activity — flying, using another Delta card, or shopping through Delta's partners — your miles will not expire. If your account becomes inactive, miles can expire after 24 months of no activity.

Can I get the welcome bonus again if I had a Delta card before?

American Express has rules about how often you can receive a welcome bonus on the same card. Generally, you must wait a certain period after closing a card before you are may be able to access for another bonus on that card. Check your cardmember agreement or contact American Express for the specific rules that explore to you.

Are there other ways to earn Delta miles besides the credit card?

Yes. You earn miles by flying Delta, staying at partner hotels, renting cars through Delta partners, and shopping through the Delta SkyMiles shopping portal. Some credit cards from other issuers also earn Delta miles. The American Express Delta card is just one way to accumulate miles, though it is often the fastest for frequent Delta travelers.
