Delta Platinum Amex pros and cons

Delta Platinum Amex welcome offer
New Delta Platinum Amex cardmembers can earn 90,000 bonus miles after spending $4,000 in eligible purchases in the first six months of card membership. This offer ends on Oct. 29.
Based on TPG’s September 2025 valuations of Delta miles at 1.15 cents each, this bonus is worth $1,035. This is the highest bonus we tend to see on this card, and was last offered in July.
However, you likely won’t be eligible for this welcome offer if you have this card or have had it before. Amex may also consider the number of American Express cards you’ve opened and closed and other factors when deciding whether you’re eligible to earn the welcome offer.
Delta’s cards are subject to American Express’s family restrictions for earning welcome bonuses, so if you’ve had a higher-tier Delta Amex card in the past, you may not be eligible to earn the welcome bonus on the Delta Amex Platinum.
Luckily, Amex will notify you if you aren’t eligible for a welcome offer, displaying a message soon after submitting your application. So, don’t ignore any messages or warnings that appear after you hit submit.

Delta Platinum Amex benefits
The Delta Platinum Amex offers many perks for Delta flyers; let’s take a closer look at all of the card’s perks and benefits. (Enrollment is required for select benefits, and terms apply.)
Elite status perks
Delta credit cards help cardmembers earn elite status with one metric: MQDs. Delta Platinum Amex cardmembers earn 1 MQD for every $20 spent, with no limit on how many MQDs can be earned through credit card spending.
They also receive an MQD boost of 2,500 MQDs at the start of each Medallion Qualification Year.
Annual companion certificate
The other primary benefit offered by the Delta Platinum Amex is an annual companion certificate. You’ll receive this perk each year after your account renewal.
The Delta companion certificate is valid for round-trip, main cabin domestic travel (booked in fare classes L, T, U, V or X). All you’ll need to pay for the companion ticket is taxes and fees. Note that this excludes the carrier’s basic economy tickets (which are booked into E fare class) and most higher-priced economy classes.
This certificate covers travel to all 50 U.S. states (including Hawaii and Alaska), the Caribbean, Central America and Mexico.
If you use this certificate for expensive flights, you can easily cover most (or all) of the card’s annual fee.
Other travel perks
The Delta Platinum Amex also offers several other benefits you may find helpful, including:
(Enrollment is required for select benefits; terms apply.)
*Enrollment in the Hertz Gold Plus Rewards Program is required; terms apply.
Fortunately, Delta ties benefits such as the checked baggage allowance and priority boarding to your Delta SkyMiles account. So, you don’t need to book flights with your Delta Platinum Amex to get access to these perks.
Additionally, cardmembers who are not SkyMiles Medallion Members are eligible to receive complimentary upgrades for Delta One (within the U.S.), first class and Delta Comfort+ after Medallion Members and Delta SkyMiles® Reserve American Express Card cardmembers.

Earning miles on the Delta Platinum Amex
You’ll earn Delta SkyMiles when you make eligible purchases with the Delta Platinum Amex. In particular, you’ll earn Delta miles with your card as follows:
- 3 miles per dollar spent on purchases made directly with Delta and hotels worldwide
- 2 miles per dollar on purchases made on dining at restaurants worldwide (including takeout and delivery in the U.S.) and at U.S. supermarkets
- 1 mile per dollar on other eligible purchases
Since TPG’s September 2025 valuations peg Delta SkyMiles miles at 1.15 cents each, you’ll get an effective return of 3.5% on purchases with Delta and at hotels, 2.3% on purchases on dining at restaurants and U.S. supermarkets, and 1.2% on other purchases.
Though a loyal Delta traveler may enjoy earning bonus SkyMiles on these purchases, none of these returns are close to the best you can do in these categories with other cards like the Chase Sapphire Reserve® (see rates and fees).

Redeeming miles on the Delta Platinum Amex
Delta’s SkyMiles program doesn’t have the best reputation among points and miles buffs. After all, Delta has devalued its miles many times over the years. And Delta doesn’t publish an official award chart, meaning award costs can be very high.
Despite that, there are still some great ways to get value from the Delta SkyMiles program.
For example, Delta has frequent flash sales. In the past, we’ve seen deals like domestic awards from 2,000 SkyMiles one-way, flights to Alaska for as little as 5,000 miles round-trip, transcontinental awards from 10,000 miles round-trip and flights to Europe from 16,000 miles round-trip.
Consider snagging some great sweet spots when using SkyMiles to fly Delta partner airlines. This includes awards on SkyTeam partners such as Air France and Korean Air, but the program also has some nonalliance partners.
Just note that some partner awards don’t show on Delta’s website, including awards on Air Tahiti Nui, Czech Airlines and Kenya Airways. As a result, you’ll want to use ExpertFlyer (owned by TPG’s parent company, Red Ventures) or another SkyTeam website like Flying Blue to find availability before calling to book awards on these partners.
TPG principal spokesperson Clint Henderson redeemed just over 73,000 SkyMiles for a flight from Mexico City to Brisbane, Australia. With this redemption, Clint secured a lie-flat Delta One seat on the leg from Los Angeles to Brisbane.

Bottom line
The Delta SkyMiles Platinum American Express Card can be a great addition to your wallet if Delta is your preferred airline. Its annual fee may seem high compared to the lower annual fee Delta Gold Amex, but you get useful benefits in return, like the annual companion certificate that can provide significant value.
However, having the card may be hard to justify if you don’t fly Delta often enough to maximize this card’s benefits.
Remember that to maximize your overall travel earning strategy, you’ll likely want to pair the Delta Platinum with another card that earns more points in bonus categories.
