Delta SkyMiles Platinum Amex Review: Worth $350 in 2026?

Key Points

  • The Delta SkyMiles Platinum Amex earns its $350 annual fee for regular Delta flyers who use the annual Companion Certificate and free first checked bag.
  • Best for travelers who fly Delta two to four times a year, mostly in domestic main cabin, and want a modest push toward Medallion status without paying $650 for the Reserve.
  • The card is outclassed for non-Delta travelers and for heavy Delta flyers who would benefit more from the Reserve's Sky Club access and larger Status Boost.

Introduction

If you fly Delta a few times a year and you've been wondering whether the Delta SkyMiles Platinum American Express Card is worth $350 in 2026, the short answer is: it depends almost entirely on whether you'll use the annual Companion Certificate. That single benefit can pay the fee twice over on one trip. Skip the certificate and the math changes fast. This Delta SkyMiles Platinum Amex review walks through the earning structure, the perks that actually move the needle, the perks that look bigger than they are, and which Delta flyer this card is built for in 2026.

Quick Summary

Best For: Delta loyalists who fly two to four domestic round-trips a year and travel with a partner. Standout Benefit: Annual Companion Certificate (one domestic round-trip in main cabin, you cover taxes and fees). Biggest Drawback: No Sky Club access, no Priority Pass, no real lounge benefit at all. Annual Fee: $350.

Card Overview

The Delta SkyMiles Platinum American Express Card sits in the middle of Delta's co-branded Amex lineup. Below it: the Delta Gold ($150) and the entry-level Delta Blue ($0). Above it: the Delta Reserve ($650), which is the one with Sky Club access. The Platinum is the version Delta and Amex aim at the regular flyer who isn't quite ready for a $650 commitment but wants more than the Gold's basics.

The fee climbed to $350 in the 2024 refresh and stayed there through 2026. That's the number you have to clear with the perks for this card to be worth carrying.

Earning Structure

The card earns:

  • 3x SkyMiles on eligible Delta purchases.
  • 3x on hotel stays booked directly with the hotel.
  • 2x at restaurants worldwide, including takeout and delivery in the U.S.
  • 2x at U.S. supermarkets.
  • 1x on everything else.

Two things to call out. First, "hotels booked directly" means the hotel's own website or front desk, not Expedia or Booking.com. Miss that and the rate drops to 1x. Second, "U.S. supermarkets" excludes Walmart, Target, and warehouse clubs like Costco. The merchant coding follows Amex's standard rules, which means superstores don't count.

If you're carrying the Amex Gold (4x at U.S. supermarkets, capped at $25,000 a year) or the Blue Cash Preferred (6% at U.S. supermarkets up to $6,000), you'll keep using those for groceries. Same goes for dining if you have the Gold's 4x there. The Delta Platinum's 2x and 3x rates aren't class-leading; they're decent backup rates on a card you're already carrying for the Delta-specific perks.

SkyMiles are worth roughly 1.2 cents each on average in 2026, depending on the redemption. Not the strongest currency in the points world, but solid for domestic Delta flights when the cash price is high.

The Companion Certificate

This is the headline. Renew the card each year and you get a Companion Certificate good for one round-trip in domestic main cabin (with some Caribbean and Central American destinations included as of recent updates). You pay the taxes and fees, which typically run $80 to $150 depending on the route. Your companion flies for the cost of those taxes.

A round-trip from New York to Los Angeles in main cabin runs $400 to $600 most of the year. A round-trip to Seattle or Denver lands in similar territory. Use the certificate on a flight where the cash price is $450, and you've covered the $350 fee plus an extra $100 in the first year alone.

The catch: you have to actually use it. The certificate is single-use and doesn't roll over. You also have to book it on Delta-operated, Delta-marketed flights, and codeshares with partners don't count. The seats also have to be available in the relevant fare class, which on peak holiday weeks can be a problem. Plan a few weeks out and you'll usually find what you need.

If you and a partner take one Delta trip together a year, the certificate alone justifies the card. If neither of you flies Delta with regularity, the certificate is a perk you'll forget to use.

Free First Checked Bag

You and up to eight people on your reservation get the first checked bag free on Delta-operated flights. At $35 per bag each way, that's $70 per person on a round-trip. Two travelers, two trips a year: $280 in bag fees avoided. Four travelers, two trips: $560.

This is the perk that quietly makes the card worth carrying for families. It also stacks with the Companion Certificate, so on one trip you can save the cash fare for your companion and the bag fees for both of you.

Priority Boarding and 20% Inflight Savings

Sky Priority boarding (Delta's branded version of priority boarding) is a real perk for anyone who carries on. You get on early, your bag goes overhead in your row, you're not gate-checking. Worth it if you fly enough to value it.

The 20% savings on inflight purchases (food, drinks, headphones) comes back as a statement credit. Not a major perk, but it's something. If you spend $30 on a flight, you save $6.

Status Boost and the Path to Medallion

Delta restructured Medallion qualification in 2024 to use Medallion Qualification Dollars (MQDs) only. MQMs are gone. The Platinum card gives you a one-time-per-year Status Boost: spend $25,000 on the card in a calendar year and earn 2,500 MQDs.

For context, Silver Medallion in 2026 requires 5,000 MQDs, Gold requires 10,000, Platinum requires 15,000, and Diamond requires 28,000. Delta has adjusted these thresholds in recent years, so check the current numbers if you're tracking toward a tier.

That 2,500 MQD boost gets you halfway to Silver if you're starting from zero. If you're already flying enough to be near a status threshold, it can push you over. If you're not flying Delta much at all, $25,000 in spend for 2,500 MQDs isn't a strong return. You'd earn more value running that spend through a card with a stronger general earn rate.

Pros and Cons

Pros

  • Companion Certificate alone can offset the $350 fee with one trip.
  • Free first checked bag for cardholder plus eight companions on the same reservation.
  • Sky Priority boarding on every Delta flight.
  • 3x on Delta and direct hotel bookings is competitive for a co-branded airline card.
  • Status Boost gives a small but real path toward Silver Medallion.

Cons

  • $350 annual fee is real money if the certificate goes unused.
  • No Sky Club access (that's Reserve territory).
  • No Global Entry / TSA PreCheck credit (the Amex Platinum personal card has this; the Delta Platinum does not, as of 2026).
  • 1x earning on most non-bonus categories is weak for a $350 card.
  • Status Boost requires $25,000 in spend, which is a lot for a 2,500 MQD return.

How It Compares

vs. Delta SkyMiles Gold ($150)

The Gold earns the same 2x on dining and U.S. supermarkets, the same 3x on Delta purchases, and includes the free first checked bag and priority boarding. What it doesn't include: the Companion Certificate or the Status Boost. If you don't use the certificate, the Delta SkyMiles Gold does most of what the Platinum does for $200 less. The Companion Certificate is the only reason to step up.

vs. Delta SkyMiles Reserve ($650)

The Reserve adds Sky Club access (Delta's lounges, not Priority Pass), a much larger Status Boost, and a Companion Certificate that includes premium-cabin upgrades on some fare classes. If you fly Delta enough to use the Sky Club five or more times a year (typical day-pass cost is $50 each), the Reserve's lounge access alone offsets most of the gap. For lighter Delta flyers, the Delta SkyMiles Reserve is overkill. For heavier flyers, the Platinum is undersized.

vs. Chase Sapphire Preferred ($95)

This is the comparison that matters for anyone who isn't married to Delta. The Chase Sapphire Preferred earns 2x to 5x on travel and dining, has a $95 fee, and its Ultimate Rewards points transfer to 11+ airline and hotel partners (including Air France/KLM, which can book Delta flights at often-better rates than SkyMiles). If you fly multiple airlines, the Sapphire Preferred is the more flexible card. The Delta Platinum only wins when you specifically want Delta perks: the certificate, the bag, the priority boarding.

Who Should Get the Delta Platinum Amex

Great Fit For

  • Regular Delta flyers (two to four round-trips a year) who travel with a partner and will use the Companion Certificate.
  • Families who fly Delta and would otherwise pay multiple checked-bag fees per trip.
  • Travelers chasing modest Medallion status who fly Delta enough that the Status Boost matters at the margins.

Not Ideal For

  • Anyone who flies Delta once a year or less. The certificate goes unused, and the fee outweighs the perks.
  • Heavy Delta flyers who want lounge access. Step up to the Reserve.
  • Travelers who fly multiple airlines. A flexible-points card like the Chase Sapphire Preferred or Capital One Venture X is the better core card.
  • Anyone who books most hotel stays through OTAs. The 3x hotel rate only applies to direct bookings.

The Annual Fee Math

Here's how to size it up before you apply:

  • $350 annual fee.
  • One Companion Certificate used on a $450 round-trip = $350 in value (you pay roughly $100 in taxes/fees).
  • Free first checked bag: two trips, two people = $140 saved.
  • Priority boarding, 20% inflight savings, 3x earning on Delta = bonus value, hard to quantify but real if you fly Delta with any regularity.

If you'll use the certificate, you're at break-even before the bag fees and earnings come in. If the certificate goes unused, you're starting at -$350 and trying to claw it back with bag fees and 3x miles, which is harder than it looks.

Final Verdict

The Delta SkyMiles Platinum Amex is a good card for the specific reader it's built for: someone who flies Delta a handful of times a year, books mostly in main cabin, and travels with a partner who'd benefit from the Companion Certificate. For that reader, the $350 fee is easy to justify in the first year and continues to earn its keep as long as the travel pattern holds.

For everyone else (occasional Delta flyers, heavy Delta flyers who'd get more from the Reserve, multi-airline travelers who want flexibility) the math doesn't work, and there are stronger options.
