Delta SkyMiles® Blue American Express Card Review

Based on verified issuer data, the Delta SkyMiles® Blue American Express Card is the only card in Delta’s SkyMiles lineup that never charges an annual fee, not a first-year waiver like its Gold, Platinum, and Reserve siblings, but a permanent $0. Here’s the math: a $1,000/month spender across Delta purchases, dining, and everything else nets $280 in year one and $180 every year after, with zero fee to offset, ever.

That’s the short version. The longer version is that this card earns SkyMiles at a modest rate, 2x on two everyday categories and 1x on everything else, which makes it the weakest earner in the Delta lineup on paper, but the complete absence of a fee means there’s no downside cost to weigh against that.

Cardholders report the appeal here is simplicity: no fee, no break-even math, no annual review of whether the perks still justify the cost. The tradeoff is real too. SkyMiles are locked to Delta and its partners, and this card carries none of the checked-bag, lounge, or companion-certificate benefits that start at Gold.

This review walks through the sign-up bonus math, the category earning table, redemption realities, and an honest comparison against a flat 2% cash-back card, so you can see exactly where this card wins and where it doesn’t.

Who This Card Is For

Three spending profiles cover most applicants for this card.

An occasional Delta flyer who wants a no-cost way into the SkyMiles program is the clearest fit. Spend $250/month on Delta purchases and this card earns 2x miles, uncapped: 6,000 miles a year, worth $60 a year at the guaranteed 1-cent baseline used throughout this review, for a card that costs nothing to hold.

Someone who eats out often, delivery included, gets the same math on the restaurant side. $250/month at restaurants worldwide (incl. U.S. takeout/delivery) earns 2x miles, uncapped: another 6,000 miles, another $60 a year, stacking on top of the Delta-purchases category without any annual fee eating into either. For a side-by-side against cards purpose-built for dining specifically, see our best credit cards for dining roundup.

A third profile, someone whose spending sits mostly outside these two categories, say $500/month on gas, utilities, and general retail, earns just 1x miles on that portion: 6,000 miles a year, worth $60. That’s a base rate no better than plenty of other no-fee cards, and it’s the honest limit of what this card offers a reader who doesn’t shop much at Delta or restaurants.

Approval-wise, Amex doesn’t publish a numeric minimum for this card; secondary sources describe it as needing Good credit. See our what is a good credit score guide for what that means for your own approval odds.

Skip this card if you want a free checked bag, Delta Sky Club access, or a companion certificate. All three require moving up to Gold, Platinum, or Reserve. A reader who doesn’t fly Delta at all is probably better served by a flat-rate cash-back card instead. This card’s permanent $0 fee also puts it on the shortlist for our best no-annual-fee travel cards roundup, worth a look if a genuine $0-fee travel card model interests you beyond just Delta miles specifically.

The Sign-Up Bonus: Is It Worth It?

10,000 Bonus Miles after $1,000 in 6 months, about $167/month.

At the guaranteed 1-cent baseline used throughout this review, 10,000 miles is worth $100. Using the standard worked profile above ($250/month Delta purchases, $250/month restaurants worldwide, $500/month everything else), net first-year value comes out to: $100 bonus + $180 in ongoing year-one rewards – $0 fee = $280 net first-year value.

Is $1,000 in 6 months a realistic bar? Yes, plainly, and it’s an unusually easy one. About $167/month is achievable through ordinary spending in a couple of months without changing habits at all. Compared to the rest of the Delta lineup, where sign-up bonuses run tens of thousands of miles against spend requirements in the thousands of dollars, this is probably the easiest bonus to earn across all four cards, smaller in absolute size, but far less work to unlock.

The trade is honest: a $100 guaranteed value is modest next to Gold’s $800-plus bonus. But Gold asks for $2,000 in spend and carries a $150 fee starting in year two. This card asks for a fraction of that spend and never charges anything at all.

Earning Rewards: The Math

This card has the standard two-category structure: 2x on Delta purchases, 2x on restaurants worldwide, 1x on everything else.

Delta purchases and restaurants worldwide, incl. U.S. takeout and delivery, are both everyday categories rather than niche ones. A reader doesn’t need to change spending habits to hit these categories, booking a Delta flight, commuting, or grabbing dinner all count.

Neither 2x category carries an annual cap. That’s worth stating plainly, some competing no-fee cards cap their bonus categories at a few thousand dollars a year; this one doesn’t.

On the standard worked profile above, total spend is $1,000/month, $12,000/year, earning 18,000 miles a year, worth $180 a year at the 1-cent baseline.

Here’s the honest comparison: a flat 2% cash-back card on that same $12,000/year mix earns 2% x $12,000 = $240 a year, more than this card’s $180 a year on this specific profile. The $500/month “everything else” slice, earning just 1x, or 1% effective, drags the blended rate below 2%. See Cash Back vs Travel Rewards for the general framework behind that tradeoff.

The flip side matters too. A reader who concentrates more spend into Delta purchases and restaurants, and less into everything else, comes out ahead of a flat 2% card, since 2 miles at 1 cent equals 2% effective on those two categories as well. The real advantage here shows up in spending mix, not in beating a flat-2% card outright on total spend.

Unlike its Gold, Platinum, and Reserve siblings, this card carries zero annual fee to weigh against that finding. The comparison above is a pure rewards-rate trade-off, not a fee-vs-rewards one, there’s no cost on this card to offset in the first place.

Redeeming Rewards

Delta SkyMiles have no fixed cash value. Unlike a fixed-cent cash-back rate or a portal-rate redemption, the actual value of a mile depends on the specific flight, route, and date booked. The $0.01/mile figure used throughout this review is a conservative guaranteed baseline for comparison purposes, not Delta’s actual award-flight redemption value, which can run higher or lower depending on what you book.

Redemption options, in order of typical value: award flights on Delta or partner airlines are the main use case for SkyMiles and typically deliver the best value. Pay with Miles, applying miles toward a cash flight purchase, is more flexible but generally redeems at a lower value than award flights.

The redemption trap to watch for: Pay with Miles and some low-value “reward” flights redeem well under the 1-cent baseline used here. Check the cents-per-mile value before booking rather than assuming your miles are always worth at least a cent.

There are no transfer partners. SkyMiles are Delta’s own currency, not a transferable bank-points currency like Amex Membership Rewards or Chase Ultimate Rewards. Overall complexity is moderate: earning is simple, but getting full value out of redemptions takes some homework.

Fees and Costs

$0 a year, and unlike every other card in the Delta lineup, this fee never changes. It isn’t a first-year waiver that jumps to an ongoing charge, it’s permanent. There’s no break-even calculation to run here, because there’s no fee to offset in the first place, a genuine, distinctive strength against Gold, Platinum, and Reserve, all of which carry an ongoing fee after a waived first year.

19.49%–28.49%, carry a balance and the rewards disappear fast. There’s no 0% intro APR offer of any kind on this card. It also doesn’t offer balance transfers at all, Amex’s own rates-and-fees disclosure lists no balance transfer APR or fee for this product.

None, a real strength for a no-fee card. Plenty of no-annual-fee cards do charge a foreign transaction fee; this one doesn’t, on top of never charging an annual fee at all. See what is a foreign transaction fee for what that fee actually costs on a typical trip.

Beyond the fee itself, this card’s travel benefits are limited: Cardholders get a 20% statement credit on eligible Delta in-flight food and beverage purchases. Unlike Gold, Platinum, and Reserve, Blue does not include a free checked bag, Zone 5 priority boarding, Delta Sky Club access, or a companion certificate.

Pros and Cons

Pros:

• No annual fee, ever, not a first-year waiver like the rest of the Delta lineup
• Easy, low $1,000-in-6-months sign-up bonus requirement, about $167/month
• Uncapped 2x miles on Delta purchases and restaurants worldwide
• No foreign transaction fee
• 20% statement credit on eligible Delta in-flight food and beverage purchases

Cons:

• No free checked bag or priority boarding, unlike Gold, Platinum, and Reserve
• No Delta Sky Club access or companion certificate
• No 0% intro APR offer
• Does not offer balance transfers
• A flat 2% cash-back card can out-earn this card for spend concentrated outside the two bonus categories

How It Compares

The most natural in-family comparison is against the Delta SkyMiles® Gold American Express Card, the next step up in the same lineup.

Gold’s much bigger bonus and third bonus category, plus a free first checked bag, are worth the $150 ongoing fee for a frequent Delta flyer who spends meaningfully across all three categories and checks a bag. This card is the better choice for someone who wants Delta miles with zero cost and zero commitment.

Outside the Delta family entirely, the closest no-annual-fee alternative is the American Express Blue Cash Everyday Card, a no-annual-fee cash-back card rather than an airline-miles card. A reader who doesn’t fly Delta regularly gets more flexible value from straight cash back than from airline miles locked to one carrier.

A different airline occupies the identical $0-fee, modest-bonus tier as this card, just on a different program: the JetBlue-Barclays no-fee card matches Blue’s $0 annual fee and near-identical 10,000-point sign-up bonus, but earns 3x on JetBlue purchases and 2x on dining and groceries against Blue’s flatter 2x on Delta and dining. Between the two, the choice comes down to which airline you actually fly, not which card earns more.

Another entry-level single-airline co-brand worth weighing: the Southwest® Rapid Rewards® Plus Credit Card charges $99 every year against this card’s genuine $0 fee, but its 50,000-point sign-up bonus is five times bigger, and it adds a 10,000-point Companion Pass qualifying-point boost every account anniversary, real value this card has no equivalent for. This card remains the better choice for a reader who wants a zero-cost way into an airline program and doesn’t care which one; Southwest Plus makes sense specifically for a Southwest-loyal flyer willing to pay for the bonus and the Companion Pass progress.

One-line verdict: this card is worth it specifically for someone who already flies Delta and wants a free way into SkyMiles. A no-fee cash-back card is the better default for everyone else.

Nick’s Verdict

Based on verified issuer data, this card makes sense for a specific reader: an occasional-to-regular Delta flyer who wants a zero-cost way to earn SkyMiles and doesn’t need lounge access or a checked-bag benefit.

For a $1,000/month spender in the mix used throughout this review, this card returns $280 net in year one and $180 net every year after, with no annual fee to offset, ever.

Skip it if you’re an infrequent flyer, want a free checked bag or lounge access, both of which start at Gold and above, or would rather hold a flexible cash-back card instead of miles locked to one airline.

The fee structure alone makes this an easy card to hold indefinitely. There’s no annual review of whether the perks still justify a fee, because there isn’t one.
