Delta SkyMiles Platinum Card Review: Is the $350 Fee Worth It?

The Delta SkyMiles Platinum American Express Card sits in the middle of Delta’s personal card lineup — well above the no-fee Blue card, but a step below the lounge-access-focused Reserve. At $350 a year, it’s built around one recurring perk that does most of the heavy lifting: an annual companion certificate.

The Numbers: Is the $350 Fee Worth It?

The companion certificate, issued automatically each year on card renewal, is good for a round-trip Main Cabin ticket (you still pay taxes and fees) on Delta flights within the U.S. or to Mexico, the Caribbean, or Central America. On even a modestly priced domestic route, that can easily be worth $150–$400+, which by itself can cover most or all of the annual fee. Stack that with the free first checked bag (plus a free second bag on domestic flights) for the cardholder and up to eight companions on the same reservation, and the Global Entry or TSA PreCheck application fee credit every 4 years, and the fee clears easily for anyone who flies Delta a handful of times a year.

There’s also a status angle: cardholders earn $1 in Medallion Qualification Dollars (MQD) for every $20 spent on the card, plus a $2,500 MQD Headstart each Medallion Qualification Year — a real, if modest, boost toward elite status for frequent flyers trying to requalify or climb a tier.

Welcome Bonus: Can You Realistically Earn It?

The current offer (as of Oct 2026) is 90,000 bonus miles plus a $300 statement credit after spending $4,000 in the first 6 months, running through November 4, 2026. At a conservative 1.2¢/mile, the miles alone are worth roughly $1,080, plus the $300 credit — a strong combined return for a $4,000 spend requirement that’s spread over a generous 6-month window (about $667/month).

Standard Amex rules apply: this card is subject to American Express’s “once per lifetime” bonus rule, so you won’t qualify again if you’ve already held this exact card and received its welcome offer.

• Annual companion certificate — a round-trip Main Cabin ticket for a companion (you pay taxes/fees) on domestic or Mexico/Caribbean/Central America Delta flights, issued automatically each year on renewal.
• Free first checked bag worldwide, plus a free second bag on domestic flights, for the cardholder and up to 8 companions on the same reservation.
• Global Entry or TSA PreCheck credit (up to $120 or $85 respectively) every 4 years.
• $1 MQD per $20 spent toward Medallion status, plus a $2,500 MQD Headstart each Medallion Qualification Year.
• Discounted Sky Club day passes and standard Amex travel/purchase protections.

How It Compares to Delta’s Other Personal Cards

Platinum sits squarely in the middle of a four-card ladder:

Dropping to Gold saves $200/year but gives up the companion certificate entirely — a reasonable trade if you almost always fly solo. Stepping up to Reserve adds Sky Club access for $300/year more, which is worth it specifically for flyers who’d otherwise be paying for lounge visits or a standalone membership — see our Delta Sky Club access guide for who actually gets in and when.

Who Should Get This Card

The Platinum card fits Delta flyers who travel with a companion at least once a year and check bags — the companion certificate alone usually covers the fee for anyone using it on a reasonably priced route. It’s a weaker fit if you almost always fly solo, rarely check bags, or don’t care about MQD progress — in that case, the no-fee Blue card captures basic Delta earning without the commitment.

Bottom Line

The companion certificate is the single benefit that makes or breaks this card’s value — use it on a reasonably priced route even once a year, and the $350 fee is easy to justify. Skip the certificate entirely, and you’re paying a premium fee for earning rates that a no-fee or lower-fee card can often match.
