The Delta SkyMiles Platinum American Express Card is running its best public welcome offer in its history: up to 100,000 bonus miles for new cardholders. The offer expires July 15, 2026, giving you just a few days left to apply.
Delta has now refreshed all three of its personal SkyMiles Amex cards this cycle, and the Platinum sits squarely in the middle: bigger bonus and stronger ongoing benefits than the Gold, without the Reserve’s $650 annual fee. Here is exactly how the offer works, what the card delivers year over year, and whether the middle tier is actually the right one for you.
The 100K Welcome Offer: How It Works
The bonus is split into two tiers rather than a single lump sum:
- 80,000 SkyMiles after spending $4,000 in purchases in the first 6 months
- 20,000 SkyMiles after spending an additional $2,000 in purchases in the same 6-month window (total $6,000 required)
You do not need to track the two thresholds separately. The second 20,000-mile bonus posts automatically once your total spend crosses $6,000 within the first six months.
$1,000 a month for six months clears the full requirement for most applicants who put regular bills, groceries, and a couple of larger purchases on the card. It is a meaningfully higher bar than the Gold card’s $5,000 combined requirement, but well short of the Reserve’s $9,000 ask.
Offer deadline: July 15, 2026. You need to apply and be approved before that date to lock in the 100K offer. Applying after July 15 gets you whatever the standard public offer is at that time, which has historically been lower.
What 100,000 Delta Miles Are Worth
Delta prices SkyMiles awards dynamically, so the exact value of your balance depends on the route, cabin, and how far in advance you book. Realistic ranges:
Domestic economy (one-way): 5,000 to 25,000 miles depending on distance and demand. 100K miles can cover 4 to 20 one-way domestic flights at the lower end of that range.
Transatlantic economy (round-trip): Off-peak fares start around 30,000 to 45,000 miles round-trip; peak summer and holiday dates run considerably higher.
Transatlantic business class (round-trip): Typically 120,000 to 250,000+ miles. A 100K balance gets you close on a well-priced route but usually needs a top-up unless you catch a saver-level award.
The most realistic sweet spot for a 100K balance is one or two round-trip domestic economy flights plus a smaller redemption, or a single well-priced transatlantic economy round-trip. Business-class international awards are within reach but not guaranteed at this balance alone.
Card Benefits That Offset the $350 Annual Fee
The welcome bonus gets you in the door. Here is what keeps the card in your wallet after year one:
- Earning rate: 3x miles on purchases made directly with Delta and on eligible hotel purchases; 2x at restaurants worldwide (plus U.S. takeout and delivery); 2x at U.S. supermarkets; 1x on everything else.
- Companion Certificate: One Main Cabin round-trip companion certificate each year after card renewal, valid on domestic, Caribbean, and Central American routes. You still pay taxes and fees, typically $22 to $250 depending on the itinerary.
- Rideshare credit: Up to $10 back per month (up to $120 per year) on Uber, Lyft, Curb, and Alto rides. Requires enrollment and does not roll over month to month.
- Resy dining credit: Up to $10 back per month (up to $120 per year) at Resy-participating restaurants. Also requires enrollment.
- Delta Stays credit: Up to $150 back per year on prepaid Delta Stays hotel bookings made through delta.com.
- Global Entry or TSA PreCheck credit: Up to $120 for Global Entry or up to $85 for TSA PreCheck (not both), once every 4 to 4.5 years.
- Medallion Qualification Dollar (MQD) Headstart: $2,500 in MQDs credited annually toward Medallion status, plus $1 in MQDs for every $20 in card purchases, with no cap.
- Sky Club access: A set number of one-time Delta Sky Club guest passes each year (not the Reserve’s unlimited access), plus standard Delta boarding and baggage perks like the first checked bag free for you and up to eight companions on the same reservation.
Add up the rideshare ($120), Resy ($120), and Delta Stays ($150) credits and you are looking at up to $390 a year in credits alone, more than covering the $350 annual fee for cardholders who actually enroll and use all three. The catch, as with most credit-heavy premium cards, is that each one requires an active enrollment step. Skip the enrollment and the credit does not exist.
Gold vs. Platinum vs. Reserve: Which Delta Amex Tier Fits You
| Card | Welcome Offer | Annual Fee | Best For |
|---|---|---|---|
| Delta SkyMiles Gold | 90,000 miles ($5,000 spend) | $0 intro, then $150 | Occasional Delta flyers who want a low-fee foothold in the ecosystem |
| Delta SkyMiles Platinum | 100,000 miles ($6,000 spend) | $350 | Regular Delta travelers who want MQD Headstart and companion-certificate value without a $650 fee |
| Delta SkyMiles Reserve | 125,000 miles ($9,000 spend) | $650 | Frequent Delta flyers who want unlimited Sky Club access and Centurion Lounge on same-day Delta flights |
The Platinum makes the most sense if you fly Delta a few times a year, care about building Medallion status through the MQD Headstart, and will actually use the companion certificate at least once. If you rarely fly Delta, the Gold’s lower fee is the safer bet. If you fly Delta frequently enough to want unlimited lounge access and a same-day standby priority, the Reserve’s higher fee pays for itself faster.
Who This Card Is Not For
Skip the Platinum if you fly Delta only once or twice a year. Casual flyers rarely have $6,000 in normal spending to redirect to the card in six months, and the $350 fee is hard to justify without using the companion certificate and at least two of the three statement credits. It is also not the right pick if you want a card for other airlines and hotels; Delta miles are only useful within the Delta and SkyTeam network, and the earning rates here reward Delta ecosystem spend specifically, not general travel spend the way a flexible transferable-points card would.
Bottom Line
The Delta SkyMiles Platinum Amex is offering 100,000 miles through July 15, 2026, its highest welcome bonus on record, alongside up to $390 a year in statement credits that can more than offset the $350 fee. Apply before the deadline if you fly Delta regularly, will use the companion certificate, and are ready to enroll in the rideshare, Resy, and Delta Stays credits rather than let them go unused.

FAQ
Q: How much do I need to spend to earn the full 100,000-mile bonus? A: You need to spend $6,000 total in the first 6 months after account opening: $4,000 to earn 80,000 miles and an additional $2,000 to earn the final 20,000 miles.
Q: Is the Delta SkyMiles Platinum worth it over the Gold card? A: It depends on how often you fly Delta. The Platinum’s companion certificate, MQD Headstart, and higher statement-credit total are worth more than the $200 fee difference if you fly Delta at least a few times a year and use the credits. Occasional flyers are usually better served by the Gold’s lower fee.
Q: Does the companion certificate work for international flights? A: No. It is valid for domestic, Caribbean, and Central American round-trip flights in Main Cabin only. You still pay government taxes and fees, typically $22 to $250.
Q: Do the rideshare and Resy credits roll over if I do not use them? A: No. Both are use-it-or-lose-it monthly credits capped at $10 each per month. Unused amounts do not carry into the following month.
Q: How does the MQD Headstart help me reach Medallion status? A: The card credits $2,500 in Medallion Qualification Dollars automatically each year, plus $1 in MQDs for every $20 you spend on the card. This can meaningfully shorten the spend needed to reach Silver or Gold Medallion status if you are close to a threshold.
