We’ve detailed many of the lesser-known perks of Delta elite status, including same-day confirmed changes, gate-to-gate Porsche transfers and flexibility with flight plans when bad weather strikes. Still, there’s one perk that sits above all others when it comes to chasing status: the allure of a free seat upgrade.
There’s nothing quite as magical in commercial air travel than paying for one class of service and being upgraded into a superior cabin, be it premium economy, business or first. Upgrades, however, remain shrouded in mystery. This guide is meant to demystify the process, explaining how Delta’s upgrade process works across every possible avenue. From complimentary Medallion upgrades to SkyMiles upgrades, Global and Regional Upgrade Certificates to understanding upgrade priority, it’s all covered below.
Unlike certain carriers (we’re looking at you, American Airlines), Delta makes all tiers of Medallion members eligible for unlimited complimentary upgrades to first class and Delta Comfort+ seating on a wide array of routes. Since April 1, 2018, all Medallion members are eligible for day-of-departure unlimited complimentary upgrades to the Delta One experience on flights within the US 50 (and yes, that includes flights to Hawaii!).
Below are the Delta products that are eligible for complimentary upgrades, including paid tickets, SkyMiles award tickets, Pay with Miles tickets and SkyMiles Companion Certificates.
- Delta Comfort+ (all Delta-operated flights)
- First Class (all Delta-operated domestic flights and select short-haul international flights)
- Delta One (all Delta-operated domestic flights, including Hawaii and Alaska)
Of course, Delta’s top-tier Medallions (Diamond) get preference over lower-tier Medallions, and timing is everything. Diamond and Platinum Medallion members can clear from Main Cabin into Comfort+ immediately upon booking if space is available, while Gold members must wait until 72 hours prior to departure to clear into Comfort+, and Silver members must wait until 24 hours prior to departure. For flights with heavy loads, such as those between Atlanta (ATL) and San Francisco (SFO), the Comfort+ cabin is typically full by the time Gold and Silver Medallions are eligible to clear, though last-minute upgrades at the gate can happen.
For Delta One U.S. 50 upgrades, Medallion Members will clear on the day of departure following the same clearance priority hierarchy as First Class Upgrades, subject to upgrade availability.
It’s important to remember that complimentary upgrades might not always clear in advance when your eligibility window opens if there are no upgrades available at that time. Delta keeps a lid on that inventory, but generally speaking, inventory is tighter on popular routes between its largest hubs and also tends to be lower during popular times for business travel.
Even if you don’t clear in advance, you may still clear at the gate. If an upgrade is still not confirmed at your window and still isn’t confirmed when you check in, your pending upgrade request will be automatically added to the airport standby list for a potential upgrade at the gate before you board. You may view your spot on the standby list in My Trips, in the Fly Delta App upon check-in and on the Gate Information Display screens at the airport.
Complimentary upgrade hierarchy
Here’s how Delta will determine your spot on the upgrade list:
- Medallion Status
- Fare Class Groupings: higher-priced fares are ranked above lower-priced fare per the following order — B, M, H, Q, K, L, U, T, X, V, then SkyMiles award tickets, then Pay with Miles.
- Delta Reserve credit cardholders
- Delta Corporate Travelers (ticket must include your employer’s Corporate Ticket Designator)
- Card Members who earned the Medallion Qualification Dollars (MQD) Waiver in the current calendar year
- Date and time of upgrade request
The only notable exception here is with full Y coach fares; all Medallion members with Y class tickets are eligible for instant upgrades and will appear ahead of all other complimentary upgrade requests. Typically, passengers do not book Y tickets unless it’s very last minute or demand is unusually high, such as the last available seat on a weekend flight into the Super Bowl host city.
If two members are identical at a given level, it goes down the above list until the tie is broken. For instance, if two Platinum Medallion members are traveling on K fare tickets and one has a Delta Reserve credit card and the other does not, the card-holding passenger will be prioritized.
It’s also worth noting that upgrade certificates (RUCs and GUCs) and upgrades with miles are prioritized ahead of these complimentary upgrades; we’ll cover these wrinkles in sections below.
Exclusions and fine print
- Basic Economy (E) fares are not eligible for paid or Medallion complimentary upgrades, regardless of Medallion or other elite status.
- Delta Premium Select is not eligible for a complimentary Medallion upgrade
- Delta One seats on flights that start or end outside of the United States are not eligible for a complimentary Medallion upgrade
- Complimentary upgrades are not available for selection by any passenger while aboard the aircraft regardless of status or fare class.
- For Companion Upgrades, both passengers must be ticketed, and upgrades must be requested at least three hours before the scheduled departure of the flight.
- Except for eligible Pay with Miles tickets and eligible Award Travel tickets, Complimentary Upgrades are not eligible on fares that do not earn miles.
- Companions who change their itinerary and are no longer traveling with the higher-tiered Medallion Member after the change are not eligible for a Complimentary Upgrade at the higher-tiered member’s clearance window. If an upgrade was confirmed prior to the itinerary change, a reservation for a companion without Medallion status will be changed to reflect the original class of service for the new itinerary and they will no longer be eligible for a complimentary upgrade. If the companion is a Medallion Member, the reservation will be changed to reflect the original class of service and will continue to be eligible for an upgrade at his/her own clearance priority. If the Medallion or partner airline elite member is no longer traveling on their original reservation, the companion traveling on the original reservation will no longer be eligible for complimentary Delta Comfort+ seating, and their Delta Comfort+ seat assignment may be removed.
Improving your chances
Beyond racing for a higher tier of Delta’s Medallion status, you can better your chances of receiving a complimentary upgrade by opening a Delta Reserve credit card (which also nets you complimentary access to Delta’s global network of Sky Club airport lounges).
- Delta Reserve® Credit Card from American Express ($450 annual fee; (See Rates & Fees) 40,000-mile welcome bonus plus 10,000 Medallion Qualification Miles after you spend $3,000 in purchases on your new card in your first 3 months).
- Delta Reserve for Business Credit Card ($450 annual fee; (See Rates & Fees) 40,000-mile welcome bonus plus 10,000 Medallion Qualification Miles after you spend $3,000 in purchases on your new card in your first 3 months)
If possible, consider booking a corporate ticket through your employer. Also, if you’re a Platinum/Diamond Medallion with free same-day change abilities, you can sniff around and change to a less popular routing on your day of departure. ExpertFlyer is a great tool for searching flights, as you can use the Flight Availability functionality to get an idea of how many seats remain open/unsold.
Speaking of, you’ll do better if you avoid peak business travel periods. This enables you to compete with fewer frequent flyers. We’d recommend flying early in the day on Saturday or in the middle of the day on Tuesday — two periods where business travel tends to be quieter. Whatever you do, avoid flying Sunday night, Monday morning and pretty much all day Friday if you want to sidestep top-tier business travelers.
If you’re searching for the crème de la crème of Delta upgrades — the FastPass of seating — look no further. Delta offers two types of dedicated upgrade certificates known as GUCs and RUCs, and the only way to get them is to become a Platinum or Diamond Medallion and select them using your Choice Benefits. In other words, they’re hyper-exclusive and thus extremely powerful. Upgrade Certificates have a higher priority than Medallion Complimentary Upgrades and may be requested and, subject to availability, cleared when you book your ticket.
Global Upgrade Certificates, available exclusively for Diamond Medallion Members, offer upgrades on both international and domestic flights with Delta along with select flights with KLM, Air France, Virgin Atlantic, Korean Air and Aeromexico. Regional Upgrade Certificates, available for Diamond and Platinum Medallion Members, offer upgrades on the same routes as Medallion Complimentary Upgrades, including all flights with First Class and the domestic Delta One experience.
As a Choice Benefit selection, Diamond Medallion Members may choose any of the following three options as one of their selected benefits:
- Four (4) Global Upgrades
- Eight (8) Regional Upgrades
- Two (2) Global Upgrades and four (4) Regional Upgrades
Platinum Medallion Members may choose four (4) Regional Upgrades as their single Choice Benefit.
In other words, if you want one of the coveted Global Upgrade Certificates, you’ll need to first achieve Delta’s highest published Medallion tier of Diamond.
Important notes about Global and Regional Upgrade Certificates
Of course, these certificates have a number of quirks and nuances of which you need to be aware. For starters, each RUC/GUC is for one-way travel, so you’d need to burn four to take you and a guest on a round-trip itinerary. You can apply a RUC or GUC to a paid ticket, a Pay with Miles ticket and a Companion ticket. Crucially, you cannot apply a RUC nor a GUC to a SkyMiles award ticket nor a Basic Economy (E fare) ticket regardless of your Medallion status level.
While these certificates are not fully transferable to others, Delta will allow you to apply your RUC or GUC to a guest’s ticket so long as that person is traveling on the same flight with you. Even if you’re booked on separate reservations (e.g. your company books your economy ticket and you book your spouse’s economy ticket later), you can use your Upgrade Certificates for both passengers.
Each GUC/RUC expires one year from the date it’s issued. This is vital, as the certificate must be burned on a flight that is completed by that one-year mark, not just ticketed! To maximize your time to use the certificate, we recommend setting a reminder for Jan. 31, and selecting your RUC/GUC Choice Benefit on the last possible day of the Medallion year.
Each certificate may be used to upgrade on Delta Air Lines or certain Delta Connection operated flights on published retail fares booked in P, A, G, W, Y, B, M, H, Q, K, L, U, T, X or V class and upgrade into RY/OY class, and may also be used to upgrade on Pay with Miles tickets and Companion Certificates.
For travel on KLM-operated, Delta-marketed flights this certificate may be used to upgrade on published fares booked in Y, B, M, H, Q, K, L, U, T, X or V class and all fare classes upgrade into Z class. For travel on KLM-operated flights marketed by either Delta or Air France, this certificate may be used to upgrade on published fares booked in Y, B, or M class. Fares booked in B or M are eligible to upgrade into O class, while fares booked in Y are eligible to upgrade into Z class.
For Air France-operated flights marketed by either Delta, KLM, or Air France, Y, B, or M fare can upgrade into A class (Premium Voyageur class). In addition, customers booked in an Air France-marketed and operated W or S class as well as customers booked in an Air France-operated, Delta-marketed P, A, or G class can upgrade to O class (Affaires or Business Class).
For travel on Aeromexico operated, Delta marketed flights this certificate may be used to upgrade on Delta’s published fares booked in W, Y, B, M, H, Q, K, L, U, T, X or V class and all fare classes upgrade into Aeromexico’s O class. Valid on Delta-marketed, Virgin Atlantic-operated flights for use globally on published Economy Cabin fares booked in W, Y, B, M, H, Q, K, L, U, T, X or V class to Upper Class. Valid on Delta-marketed, Korean Air-operated flights for use globally on Delta’s published fares booked in Y or B class to Korean Air’s Z class, or booked in M class to Korean Air’s O class.
Here are some final, nitty-gritty aspects of these certificates:
- Finding flights: Upgrade Certificates can be used on any Delta-operated flight, and select partner-operated flights with KLM, Air France, Virgin Atlantic, Korean Air and Aeromexico.
- Enjoying priority: Upgrade Certificates will clear off the waitlist in order of Medallion Tier then the day and time your request was added to the list. If you’re on the Airport Standby List, Upgrade Certificates receive higher priority than Medallion Complimentary Upgrade requests.
- Ticket eligibility: Upgrade Certificates can be used on most paid tickets, Pay with Miles tickets, and Companion Certificates. They cannot be used on Award Travel or tickets booked in Basic Economy (E).
- Redemption period: Certificates expire a year after they are selected. Certificates must be used on flights flown within the 12-month period — otherwise, the certificates will expire.
- Flexibility: If you have to change or cancel a reservation where an Upgrade Certificate has already been applied and confirmed, you will not lose the certificate. You can either call reservations to apply the Upgrade Certificate to your new flight, or it will automatically be reopened in your account within 2-3 weeks.
- Application: You can waitlist for multiple flights days, weeks or even months apart with the same certificate; this is important because time of upgrade request is a tiebreaker. If the earlier flight doesn’t clear, you still have the originally requested date on the second flight (though if first flight does clear, you’ll need to re-request an upgrade on the second flight with a new certificate/request date).
How to use an Upgrade Certificate
It’s a pain (and Delta knows it), but as of now you still have to call Delta to use a GUC/RUC — they cannot be applied online or via the Fly Delta app. You’ll need to dial the phone number given with your associated Medallion tier or the general hotline at 800-323-2323 and make the request. Be sure to call at least 3 hours prior to departure to apply your certificate, though 24 hours prior to departure is strongly recommended. The earlier the better, and remember that you have to do this over the phone; gate agents cannot apply upgrade certificates at the airport.
We generally recommend calling in when you’re first looking to book and playing around with potential booking dates until the Delta agent finds a date where your upgrade certificate will clear immediately. If you can avoid waitlisting, do so. Waitlists are not guaranteed to clear, and on particular routes — such as west coast gateways to Hawaii — they’re known to rarely, if ever, clear.
On itineraries with connections, be sure to ask the Delta agent to place upgrade priority on the leg that matters most to you. If you don’t clarify this, upgrades can clear on relatively unimportant/short legs, while you remain waitlisted on the long leg. If you don’t place priority on the hard-to-get leg, and the upgrade clears on any other leg, your upgrade certificate is considered used. For example, you don’t want to burn a valuable Global Upgrade Certificate on a 45-minute domestic positioning leg when the leg that matters is the long-haul ride from the US to Europe, Asia, Oceania, etc. Remember, there’s no way to “undo” an upgrade clearing. Once it’s burned, it’s burned.
While it’s possible for upgrade requests on the waitlist to be cleared before you get to the gate, it is more likely that they will be cleared at the gate prior to departure. If your certificate doesn’t clear, it will be automatically reissued to your account.
SkyMiles Mileage Upgrades
While we at TPG typically recommend storing up SkyMiles until you’re able to exchange them for a complete free ticket (like a 100,000-mile one-way business class flight from the US to the Maldives, which would otherwise cost upwards of $5,000!), that’s not always practical for infrequent flyers. Delta allows its passengers to upgrade their existing tickets with SkyMiles regardless of status, with two methods of doing so.
Upgrade with Miles
The first is Upgrade with Miles, which occurs during the booking process. You can use SkyMiles to upgrade to Delta One, Delta Premium Select, First Class or Delta Comfort+ for eligible flights within the United States while you’re purchasing an original ticket either at delta.com or with Delta phone reservations. If your reservation is eligible for an upgrade, you’ll see the option to upgrade in your Trip Summary.
Delta typically prices mileage upgrades by placing a value of 1 cent on each SkyMile — that’s a fairly terrible redemption. In other words, if Delta is charging $60 for a particular seat upgrade, it’ll also allow you to part ways with 6,000 SkyMiles to achieve the same upgrade.
We typically recommend that you try to book award tickets with an outsized value of 3 to 5 cents per SkyMile. While it’s convenient to just exchange a bundle of miles for a cabin upgrade, remember that in doing so you aren’t extracting maximum value from your SkyMiles balance.
Mileage Upgrade Awards
It’s easy to confuse this process with the aforementioned Upgrade with Miles due to the similar naming conventions, but of the two, this is the best one for squeezing maximum value from your miles. Mileage Upgrade Awards can only occur after booking is complete and, for now at least, only over the phone. Unfortunately, as of February 2019, MUAs are no longer available on Delta-operated flights in the Americas.
Mileage Upgrade Awards allow you to use miles to upgrade on certain Virgin Atlantic-operated, Air France/KLM-operated and Aeromexico-operated flights. The marketing carrier is determined by the two letter airline code in the flight number. For example, DL2368 is marketed by Delta and VS18 is marketed by Virgin Atlantic. Delta-ticketed flights feature ticket numbers that begin with “006”. Any flight purchased through delta.com is ticketed by Delta; other airlines have their own unique ticket numbers. For example, Virgin Atlantic-ticketed flights feature ticket numbers that begin with “932”, even if Delta is the airline actually operating the flight.
Mileage Upgrade Awards may be redeemed for fixed mileage amounts according to area of travel and are only valid with certain fare classes. The upgrade transaction can be completed up to 24 hours prior to departure and must be booked through a phone reservations specialist.
While the rates are fixed rather than dynamic, Delta does not publish a rate chart. Based on anecdotal evidence, you should expect one-way upgrades to start at 15,000 SkyMiles per passenger and climb to upwards of 80,000 depending on how cheap your original fare was and how exclusive the upgrade. For instance, full-fare Y class economy tickets will require fewer miles than discounted T class tickets.
You’ll need to call to inquire on price, and if a specific route shows as unavailable for an upgrade you can request to be added to the waitlist. These can clear up to three hours prior to departure, so be sure to keep a healthy balance of SkyMiles in your account in the event that it does clear. Of note, these do not carry over to the airport standby waitlist.
What regions and tickets are eligible?
- As of February 2019, MUAs are not available on Delta-operated flights in the Americas.
- SkyMiles Award Tickets are not eligible for Mileage Upgrade Awards.
- For International markets, Mileage Upgrade Awards on Delta-marketed and operated flights may be used to upgrade on the following paid fare classes: Y, B, M, H, Q, or K.
- For flights marketed and/or operated by Air France/KLM, Mileage Upgrade Awards may be used for a one-class upgrade when the paid fare class is Y, B, or M.
- For Air France-operated flights, Mileage Upgrade Awards are available from Economy to Premium Economy to Business only on transatlantic Joint Venture flights between U.S. cities and Paris (CDG and ORY).
- For Delta-marketed flights operated by Virgin Atlantic, Mileage Upgrade Awards are available from Economy to Premium Economy or Upper Class, as well as Premium Economy to Upper Class. Mileage Upgrade Awards are available from Y, B, M, H, Q, and K paid fare classes from Economy Cabin and P, A, and G paid fare classes from Premium Economy.
- For Delta-marketed flights operated by Aeromexico, Mileage Upgrade Awards are available on Delta’s published fare classes in Y, B, M, H, Q, K, L, U or T for travel between the United States and Mexico.
Getting upgraded for free is a glorious thing, and you can better your chances by flying Delta more often (and in turn, climbing its Medallion elite ranks) and by carrying a Delta Reserve Credit Card or Delta Reserve for Business Credit Card. You’ll also be wise to choose flights that aren’t during peak business travel periods, and if there’s a connection involved, avoid Delta’s largest hubs like Atlanta (ATL), Minneapolis (MSP), New York-JFK and Los Angeles (LAX).
Using a stash of SkyMiles to upgrade can be a great way to boost your flight experience, but you’ll want to think carefully before using Upgrade with Miles — Delta will only allow you to extract 1 cent per SkyMile via this method. Mileage Upgrade Awards can be a more valuable route, but it’s also more cumbersome and demands more patience.
Where things really get exciting are upgrade certificates, but you’ll need to reach Platinum or Diamond to secure them. If you’re fortunate enough to have a few in your account, you can strategically plan a dream trip, pay cash for an economy seat and fly there in business class.
