Delta SkyMiles Platinum American Express

The short answer

The Delta SkyMiles Platinum American Express Card is an airline rewards card with a $350 annual fee. It adds a renewal companion certificate, credits and ways to earn toward Delta status. Despite the Platinum name, this Delta card does not include lounge access.

The certificate decides the answer, and only when an eligible fare is available. In Julia's example, suitable domestic tickets cost $360 each, $720 in all, or $705.60 net after a 2% card's rewards. With the certificate, a $430 primary fare plus $40 for the companion costs $470 and nets $455.90 after Platinum's miles.

That saves $249.70 and leaves $100.30 of the fee to justify. If the primary fare is $650 instead, the saving is only $36.30 and $313.70 is left.

So the card suits two people who can travel together on fares the certificate covers and who would use the other credits anyway. It suits less well a household with fixed dates and poor availability, or one that would pick a worse schedule to redeem the certificate. The Studio's verdict on fit is "Delta loyalty, when the benefits of this tier match actual use." Its Wallet Score is 70 out of 100.

What it costs

The annual fee is $350, and the Studio's rate card lists no membership cost. The certificate arrives after card renewal, so Julia would not plan to use it right after opening a new account. The Studio's test also covers a year without the biggest benefit.

For the trip, the comparison is the same tickets bought outright, with a no-fee 2% card earning $14.40 on $720. For bags, Julia also compares the lower-fee Delta Gold card, which offers bag benefits too.

What it earns

• 3 miles per dollar on eligible direct Delta and hotel purchases.
• 2 miles per dollar at restaurants and U.S. supermarkets.
• 1 mile per dollar elsewhere.

Julia values a mile at 1 cent toward travel she would otherwise buy, and the Studio's rate card uses the same 1 cent. She compares these rates with cash back and would leave everyday spending on another card where that pays more.

The card also supplies 2,500 Medallion Qualification Dollars each qualification year and earns 1 more for each $20 of eligible purchases. These measure progress toward status. You cannot spend them on a ticket, so Julia keeps them separate from spendable miles.

The credits, used honestly

• Companion certificate. It covers eligible Delta Main round trips within the U.S. and to specified destinations in Mexico, the Caribbean and Central America. It is not a free ticket: taxes and fees remain payable, and the primary fare you must buy can be higher than the fare you would otherwise choose.
• Delta Stays. Up to $150 each calendar year for qualifying prepaid hotels or vacation rentals paid with the card. Julia compares the complete price and cancellation terms with booking elsewhere, because a higher price, different rewards or lost hotel benefits can reduce the saving.
• Rideshare and Resy. After enrollment, up to $10 monthly on eligible U.S. rideshare purchases with selected providers, and a separate Resy credit of up to $10 monthly on qualifying U.S. purchases. A month without use counts as 0, and Julia would not make extra purchases to use an annual allowance.
• Bags. The first standard bag waiver can cover the cardholder and up to 8 companions on the same reservation. The newer domestic second-bag waiver is for eligible basic cardholders, not every companion. Bags already included through a fare or status add no saving.

The catch

The certificate has conditions that matter more than its advertised ticket value. You must travel together, in the same cabin and reservation, and book both tickets at the same time. Delta Basic fares do not qualify. Only certain fare classes are available, so empty seats on a flight do not mean certificate seats are available.

Most qualifying fares need advance booking and minimum or maximum stays, and the trip must be completed before the certificate expires, not merely booked before that date. The tickets must be paid with the eligible Delta Platinum card and/or permitted eCredits. Taxes and fees remain payable; for up to 4 segments, the current domestic limit is $80, with a limit of $250 for eligible international itineraries. The companion does not earn flight miles or Medallion Qualification Dollars.

Status has its own catch. Moving ordinary purchases to earn those dollars can mean giving up better rewards, so Julia first checks the remaining status requirement and the benefits she would actually use. The Studio's limitation says: "Pay With Miles cannot be combined with TakeOff 15. Lounge comfort and status progress have no assumed cash value."

Who it fits

The card works for a couple like Julia and her partner with a domestic round trip in mind, who can search their fixed dates with the certificate selected and book an eligible Main fare in advance. If the search shows a $430 primary fare, one booking saves $249.70 against the $350 fee, and other useful benefits can cover the rest.

It fits less well a household whose search shows only a $650 fare, where $313.70 of the fee is left to justify. Julia would not add an unwanted hotel night or choose a worse schedule just to redeem the certificate.

The Wallet Score of 70 gives most weight to value after costs across the same 3 household budgets, with reward flexibility, the work involved and 2 specific protection checks completing it. The certificate is a conditional advantage: an eligible fare must be available, and the taxes are still paid. Food earnings and usable credits also help. The strong grade is a reason to check your next companion booking carefully, not to assume every couple gets the same savings.

The arithmetic

Julia's domestic round trip for 2 people:

• Without the card: $360 each is $720. A no-fee 2% card earns $14.40, so the net cost is $705.60.
• With the certificate: a $430 primary fare plus $40 of taxes and fees for the companion is a $470 card charge. At 3 miles per dollar that earns 1,410 miles, worth $14.10 at 1 cent, so the net cost is $455.90.
• Saving: $705.60 less $455.90 is $249.70, leaving $100.30 of the $350 fee to justify.
• With a $650 primary fare: the same $40 companion charge makes $690, which earns 2,070 miles. The net cost is $669.30, the saving is only $36.30 and $313.70 of the fee is left.

Status, if it mattered: being 400 Medallion Qualification Dollars short would take $8,000 of eligible purchases through the card. At 1 mile per dollar and 1 cent, that earns $80 in miles, against $160 from a 2% card, so $80 is given up to close the gap. Julia then asks what the next tier would add on trips she expects to take, leaving out the bag and boarding benefits the card already supplies.

Before you apply

On the issuer's page today, check the $350 fee, the certificate rules and which fares, cabins, destinations and fare classes qualify, the taxes and fees limits, the credit amounts and the bag waiver conditions. Then search your own dates with the certificate selected before assuming it covers the fee.

The Studio's rate card carries the companion certificate at $560, the largest of the figures its tests use, and flags it for review; Julia's own example saves $249.70. It also lists the Delta Stays credit at $150, the rideshare and Resy credits at $120 each and checked bags at $240. The terms may have moved since the video, so confirm current amounts.
