Delta allows eligible Medallion members to request Regional and Global Upgrade Certificates online during booking on Delta.com and in the Fly Delta app, though the exact outcome depends on route, cabin, and upgrade inventory.
Let’s take a closer look at what these certificates are and how to use them properly.
What is a Delta Global Upgrade Certificate?
In essence, this certificate is a prized asset for SkyMiles members, enabling them to upgrade to a superior cabin class from what they initially reserved, subject to seat availability. Upgrade certificates can be used to upgrade to the next class above the one purchased. On flights where both Delta Premium Select and Delta One are available, a passenger who has booked a seat in Main Cabin or Delta Comfort may initially be assigned a seat in Premium Select and then be placed on the waitlist for Delta One, where they will be eligible for an upgrade 24 hours before departure. Additionally, Diamond and Platinum Medallion members benefit from increased upgrade opportunities. A vital note is that these upgrades might not clear immediately, as Delta often waits until the last minute to confirm certificate upgrades based on a variety of factors, including Medallion status and purchased class of service.
Delta Airlines historically lagged in offering digital ease for redeeming upgrade certificates. These certificates, granted as choice benefits for Platinum and Diamond Medallion members, offer significant travel advantages, including priority boarding, complimentary seat upgrades, and additional baggage allowances. Members can also earn and redeem miles more efficiently, maximizing the benefits of their elite status.
- Platinum Medallion members receive 4 Regional Upgrade Certificates, redeemable only on domestic flights.
- Diamond Medallion members have the option of selecting 4 Global Upgrade Certificates, 8 Regional Upgrade Certificates, or a mix of 2 Global and 4 Regional Upgrade Certificates, available for both domestic and international flights. Additionally, members can use these certificates for premium cabin selections or to secure companion upgrades. Note that each upgrade certificate is valid for a one-way flight only, including layovers, meaning round-trip flights would require two certificates.
Fundamental Differences Between Delta Regional Upgrade and Delta Global Upgrade Certificates
Delta Regional Upgrade Certificates (RUCs) and Global Upgrade Certificates (GUCs) differ in eligibility and scope.
RUCs are available to Platinum and Diamond Medallion members and are valid on the same routes as Medallion Complimentary Upgrades.
GUCs are available only to Diamond Medallion members and can be used on Delta domestic and international flights, plus select flights on KLM, Air France, Virgin Atlantic, Korean Air, and Aeromexico.
Both certificate types have higher priority than complimentary upgrades and must be booked and flown by the end of the Medallion Year tied to the Choice Benefit selection. In general, Delta treats Upgrade Certificates as valid for a one-cabin upgrade above the purchased cabin, though the exact result depends on the route, aircraft, cabin structure, and upgrade inventory.
| Feature | Regional Upgrade Certificates (RUCs) | Global Upgrade Certificates (GUCs) |
|---|---|---|
| Who can choose them | Platinum Medallion members can choose 4 RUCs as a Choice Benefit. Diamond Medallion members can also choose RUCs as part of their Choice Benefit selection. | Diamond Medallion members only. They can choose 4 GUCs, 8 RUCs, or 2 GUCs + 4 RUCs as a Choice Benefit. |

| If Delta Premium Select and Delta One are both on the aircraft | A traveler booked in Main Cabin or Delta Comfort may clear first into Premium Select, then be waitlisted for Delta One, which can start clearing 24 hours before departure. | Same rule applies.

How to Use Delta Upgrade Certificate Online
The old process forced Medallion members to make flight bookings online and later contact Delta directly to apply their upgrade certificates. Delta has now overhauled its booking platform, allowing members to include these certificates during the checkout process. This upgrade not only simplifies the booking experience but also enhances the ability to select preferred seats and cabins, ensuring a more comfortable and efficient travel experience for all members.
The steps to employ a Delta upgrade certificate on your reservation have been simplified to an all-time ease, allowing members to quickly apply their certificates for complimentary upgrades, select preferred seats in premium cabins, and enjoy the full range of elite benefits without additional hassle:
- Navigate to Delta.com and log in to your Delta SkyMiles account.
- Search for flights.
- During checkout, look for Upgrade Certificate Request.
- Choose the flight segment and certificate type to apply the upgrade certificate — each leg of the journey requires a separate certificate (round-trips need two certificates).
- Complete booking and check whether the upgrade clears immediately or is waitlisted.
- Check your email or the Fly Delta App notifications for confirmation of your upgrade certificate or addition to the waitlist for an opportunity for a seat upgrade. Bear in mind that applying an upgrade does not always result in an immediate upgrade; the availability might influence whether you’re successful or put on standby.
Details About Upgrade Certificates
Delta’s upgrade certificates provide versatility, as they are valid not only on Delta-operated flights but also on routes covered by partner airlines such as AeroMexico, Air France, KLM, Korean Air, and Virgin Atlantic. This global network ensures that members can utilize their certificates for a wide range of domestic and international flights. It’s crucial to remember, though, that seats are subject to availability, and using an upgrade certificate doesn’t assure immediate seating upgrades. Each certificate covers a one-way trip, including layovers. If an upgrade does not clear for all legs, the certificate is still considered used, emphasizing the importance of strategic planning when booking tickets.
For those booking through Delta Vacations, the process for applying Delta upgrade certificates remains offline, requiring direct assistance from Delta staff. Members holding a Delta credit card or those with elite status can access additional benefits and personalized support to ensure their travel plans include the desired upgrades and premium services.
What is the validity period of the Upgrade Certificates?
Upgrade Certificates expire at the end of the Medallion Year associated with the Choice Benefit selection. For example, if you earn Diamond on August 1, 2026 and select certificates for 2027 status, they are valid until January 31, 2028.
Can Upgrade Certificates be used on partner airlines?
Yes, Global Upgrade certificates can also be used on select flights operated by KLM, Air France, Virgin Atlantic, Korean Air, and Aeromexico; however, the terms and conditions for using these certificates vary by partner airline. We recommend reviewing the specific guidelines for each partner airline before booking.
Are Upgrade Certificates transferable to other passengers?
Upgrade Certificates can be applied to companions traveling on the same reservation or linked reservations as the certificate holder. Each companion requires their own certificate for an upgrade. To link reservations, contact Delta's customer service.
What happens if my upgrade doesn’t clear?
If an upgrade does not clear, the outcome depends on how the certificate was applied and the itinerary involved. Members should monitor the reservation and review Delta’s current Upgrade Certificate terms rather than assume automatic redeposit in every case.
Can Upgrade Certificates be used on award tickets?
Yes, Upgrade Certificates can be applied to Award Travel tickets, Miles + Cash tickets, Pay with Miles tickets, Companion Certificates, and tickets booked as part of a Delta Vacations package. Basic Economy fares are excluded from eligibility.
Bottom Line
Delta’s online/app certificate request tool is now an established part of the booking flow, not a new launch. Today, it’s truly important to understand which routes are covered by this program, how the in-flight upgrade system works—when upgrades happen instantly and when they’re subject to a waitlist—and how the rules for partner and award tickets differ from standard paid Delta flights.
